　　Cartography: Cheng Can

　　"If there is an afterlife, do you want to be a girl or a boy?" When Wang Wenjuan, the head of the UU White Shell Project, raised this question in the public welfare class of a mountain school in Liangshan Yi Autonomous Prefecture, Sichuan Province, few people raised their hands "wanting to be a girl" on the grounds that they felt dirty and troublesome and disliked. "I want to ask this question to understand their gender identity." Wang Wenjuan said.

　　Although this public welfare class of adolescent physiological health knowledge is only for girls, the initial atmosphere is a bit embarrassing. When hearing the words "menstruation", some girls buried their heads in their arms shyly, and some blushed and rubbed their hands. Until they found that the physical and health supplies sent by Wang Wenjuan were exactly what they usually lacked; Many of the physiological coping methods mentioned are not taught by my mother or sister. The confusion about the physiological period in their hearts has been solved little by little. One, two, three … … Girls began to raise their hands to ask questions and interact, and the atmosphere gradually warmed up.

　　When Wang Wenjuan left, everyone blocked this warm-hearted little sister at the door of the classroom and hugged her. A girl insisted on sending her to the school gate and kept saying "Annigu" (Yi meaning: I love you — — Reporter’s note). A girl later wrote to tell her: "The sanitary towel you sent is like a care. I didn’t expect that I could get such meticulous care from others. I know how to protect myself in the future."

　　After entering adolescence, there are always many "question marks" in my heart.

　　During the first physiological period, Xiaofen (a pseudonym), a left-behind girl from a single-parent family in niujie Middle School, Weishan County, Yunnan Province, was not particularly panicked. She remembered what the biology teacher had said and bought sanitary napkins by herself. She didn’t feel well for a few days, but she didn’t tell her grandmother and her father who worked outside the home because she was shy. For the physiological period, she knows nothing about other precautions except that she strictly abides by her classmates’ "Don’t touch cold water and eat popsicles".

　　It was not until the social worker of the "Spring Willow" left-behind girl care project came to the school that Xiaofen participated in the accompanying activities of the "Spring Willow" class and knew how to use sanitary napkins and how to wash underwear during the physiological period.

　　Lu Ying, the director of "Spring Willow" project, and his team visited some mountainous areas in Yunnan and found that "menstrual poverty" is a common phenomenon. Some girls go to the nearest store to buy sanitary napkins, and they have to walk more than ten kilometers, and the types available are very limited; Influenced by their elders, some girls will still use traditional methods, such as toilet paper and menstrual belt, to cope with the physiological period, and social workers will learn to use sanitary napkins after repeated explanations.

　　Like Lu Ying, Ma Yali, project director of Yicang Charity Service Center in Linxia Hui Autonomous Prefecture, Gansu Province, has also discovered the problem of "menstrual poverty" of many girls in rural areas since she participated in charity activities to help poor girls in 2018.

　　When delivering "Xiao Ya Bao" including sanitary products and underwear, Ma Yali talked with local rural girls and learned that they were discovered by their mother only after the second physiological period or even the fourth or fifth time.

　　Ma Yali also learned that many rural girls generally choose "what to buy cheaply" for physical hygiene products, and even some girls don’t change sanitary napkins often during the physiological period in order to save money, and there are also cases of gynecological bacterial infections.

　　"Many girls always have a lot in their hearts after they enter adolescence ‘ Question mark ’ " In the past seven years, in order to help girls in rural areas correctly understand the knowledge of physical health, Ouyang Chenxi, co-founder of Lingmei Public Welfare Organization, has carried out related projects in Sichuan, Zhejiang and other places to help girls aged 11-19 to grow physically and mentally. When she once held an activity in Liangshan Prefecture, she found that some local girls didn’t know why their buttocks were bleeding, why they had a stomachache during their physiological period, and why they couldn’t control their emotions for a few days.

　　"Without sanitary napkins, many rural left-behind girls can’t say it ‘ Pain ’ 。” Wang Wenjuan has been doing public welfare for more than five years, and many remote mountainous areas in Yunnan and Tibet are places that he often goes to. In addition to financial difficulties, she found that local girls still have a strong sense of "menstrual shame". This sense of shame also comes from the outside world.

　　For example, I heard that Wang Wenjuan sent sanitary napkins, and some schools declined to say that "it’s easy to publicize the farewell things, but it’s hard to tell the outside world to send this (sanitary napkin)". Although some schools accept donations, Wang Wenjuan feels that the other side has a subtle attitude of "I wish I could finish donating and leave quickly". Every time this happens, she always "talks about conditions" with the school — — Adhere to the principle of "be sure to give lectures to children" and ensure that every girl who receives hygiene products can hear physiology classes and psychological counseling classes. "I want to bring love to the children by giving away hygiene products." Wang Wenjuan said.

　　Giving away physical hygiene products is like "far from hydrolysis, near thirst"

　　In Ouyang Chenxi’s view, the "menstrual poverty" of many rural girls is closely related to family economic conditions, family members and the degree of care from the outside world. No one tells them how to deal with such a private matter as the physiological period, and they don’t have much money to buy sanitary products themselves. Some left-behind girls’ daily pocket money is only more than 10 yuan. When it comes to "unlucky days", they always blush and ask their grandparents for money to "buy that".

　　"Giving physical hygiene products to girls in remote mountainous areas is like ‘ Far hydrolysis cannot quench thirst ’ 。” Wang Wenjuan knew that "menstrual poverty" could easily lead to gynecological diseases and psychological problems of adolescent girls.

　　When she was volunteering, Wang Wenjuan learned that a girl had severe dysmenorrhea, local itching and other symptoms, but there was no one at home to accompany her to see a doctor. She tried to take the half-assed girl to the local hospital, but when she heard "going to gynecology" at the door of the hospital, the girl turned her head and ran away. Wang Wenjuan later learned that this girl was very resistant to the word "gynecology" and would rather not see a doctor than go to "that place".

　　However, Wang Wenjuan has also found some positive changes in the past two years. On one occasion, she went to three township schools in Shangrao, Jiangxi Province to give away sanitary products and give public lectures. Teachers from the county school also came to attend the lecture. After class, they also invited Wang Wenjuan to give a lecture in the county, and said, "Children in the county may not need donated sanitary products, but they need such physical hygiene classes." This recognition made Wang Wenjuan feel that the effort was worthwhile.

　　“‘ Menstrual poverty ’ It is likely to affect girls’ physical and mental health development, including schoolwork. " According to Dr. Long Di, a professor at the Institute of Psychology of the Chinese Academy of Sciences and director of the Center for the Protection of Children and Families, some girls lack physical hygiene products and the intimate care of adults around them. Coupled with the mentality of menstrual shame shaped by social culture, they will have negative emotions such as tension, anxiety and fear, and even dysmenorrhea. "It is necessary to strengthen education and support for girls’ physiological period and mental health."

　　How to strengthen the physical and mental health education and support for underage girls

　　"In addition to giving rural girls more volunteer services in terms of physical health knowledge, they must be made to identify with and love women’s identity." Ouyang Chenxi has been thinking about how to add more experiential volunteer service activities to the public welfare science popularization activities of physical health knowledge in the future, so as to better perceive girls’ emotions and stimulate their self-identity and positive growth from the inside out.

　　According to Long Di, according to the UN Convention on the Rights of the Child, to realize the best interests of children should ensure the two major needs of children’s safety and development. For the healthy growth of underage girls, she believes that parents, teachers and education departments are duty-bound, especially the education department should work with relevant experts and parents to formulate effective measures to effectively protect and care for the healthy development of underage girls’ physical health.

　　In addition, Long Di mentioned that the physical and mental health education services conducted by non-governmental public welfare organizations have been formed in recent years, and some ways have been explored. It is suggested that volunteers of public welfare activities pay special attention to respecting the living customs in underdeveloped areas, and do not have the attitude of "I am right, you are backward" and "I want to change you", but should explore with the recipients how to change the customs harmful to women’s physical and mental health, so that girls in poor areas have the opportunity to create a happy life.

　　"There are too many girls who need sanitary napkins, and there are too many lists received, which are all backlogged, but the fundraising can’t keep up." At present, Wang Wenjuan is facing a lot of pressure to raise funds. She said: "Donating physical hygiene products is just a way. Wherever you donate, you should talk about the course. I hope that the needs and difficulties of poor girls can be well-intentioned and gently protected, and don’t let ‘ Menstrual poverty ’ Happened to children. " (Reporter Jiao Minlong)

"I am an engineer myself. I have done both hardware and software. Therefore, our zero run will definitely have the culture of engineers. " The founder of Zero Run once said this.

The Science and Technology Man Created by The Big Bang Theory

Zhu Jiangming and his zero-run car really have a "science and technology man" temperament. Everything is "technology is king" and independent research and development are highly respected. Judging from the S01, the first mass production car with zero running, all the core components should be self-researched, and there is already the strength of "no madness and no survival".

The industry is not the first to build such a "science man". Nowadays, the zero-running car is very much like the first electric car enterprise in China. Zhu Jiangming’s engineer temperament is also reminiscent (known as "the boatman").

BYD started its electric layout at the end of its own brand, and it caught up with the best time of electric car in China. Soon after the zero-run car started, can the running method of "self-research"+"self-construction" still win?

The tactics of technical men: super learning ability

Zhu Jiangming, founder of Zero Run Car, and Wang Chuanfu, president of BYD Co., Ltd.

"We started with the enterprise dispatching machine in 1993 and transformed the security equipment in 2001. We have experienced two successful entrepreneurial processes from 0 to 1." Zhu Jiangming recalled and said.

In 1993, 26-year-old Zhu Jiangming and Fu Liquan, the current chairman of Dahua Co., Ltd., pooled 5,000 yuan to set up Dahua in a primary school in Hangzhou and started their business. Zhu Jiangming, who graduated from Zhejiang University majoring in telecommunications, is good at embedded algorithm and chip-level combination of software and hardware at the bottom of the computer, and Dahua originally used this embedded technology for enterprise dispatching machines.

In 2001, Dahua’s main business turned to security, which made Zhu Jiangming completely a layman. By studying and studying, Zhu Jiangming led the team to develop 8-channel embedded DVR in 2002. This technical breakthrough in the security industry has enabled Dahua to enter a period of rapid development, laying a foundation for the future development of Dahua.

Zhu Jiangming, who once couldn’t tell all the camera parameters, became an expert in video security technology. HDCVI (high definition composite video interface) video transmission technology invented by Zhu Jiangming was officially released by Dahua in 2012, which triggered a technical earthquake in the field of video transmission.

As a coaxial high-definition transmission technology, HDCVI can realize the transmission of megapixel video over 500 meters, breaking through the bottleneck of resolution of traditional analog technology. In 2013, the international HDcctv Alliance announced the acceptance of HDCVI as an international standard, and HDCVI technology became the first technical specification in China security industry to be included in the international standard. In December 2014, HDCVI technology and standards were included in GA/T1211-2014 "Technical Requirements for Security and Prevention of HD Video Surveillance System".

With the invention of HDCVI alone, Zhu Jiangming opened the door to wealth and freedom. "Every year, relying on HDCVI, Zhu Jiangming can receive a lot of patent fees from all over the world." Insiders said. However, Zhu Jiangming is still not satisfied. In 2015, he decided to create a zero-running car and wanted to realize the third "0 to 1" change in his life.

Boatman: You can make everything yourself.

Wang Chuanfu, a fellow science and engineering man, is one year older than Zhu Jiangming. The advanced story of "Brother Boatman" has long been a household name in China. Comparing the two, "science and engineering men" seem to like to do the challenge of "nothing can be done".

Wang Chuanfu likes to manage enterprises by means of management technology. "Technology is king and innovation is the foundation" is the fundamental development concept of BYD put forward by Wang Chuanfu. Wang Chuanfu does not impose restrictions on BYD. He thinks that everything can be made by himself, and what is made is more useful than what is bought at a high price. He thinks that technology patents are all’ paper tigers’. The remarks that "20 engineers support a mechanical arm" and "cars are just a pile of steel" make "science man" Wang Chuanfu look simple, arbitrary and conceited. He enthusiastically pursues technological innovation. He uses strong creativity and indigenous methods to break the technical blockade. He despises unreasonable business order and game rules. His growth mode is simple and direct: if you don’t help me, I will do it myself.

In 2003, BYD produced more lithium batteries than Sanyo, Sony and Panasonic, accounting for 60% of the global market. At that time, Japanese companies had established a highly automated battery production line, and the mechanical arm could replace a lot of labor. When representatives of Japanese enterprises visited BYD, they were amazed at the production efficiency of BYD’s semi-automatic+manual "human sea tactics". In that crazy era, Wang Chuanfu made full use of domestic low-cost human resources to subvert the monopoly position of Japanese battery industry at that time.

In 2003, BYD began to transform into the automobile industry. Wang Chuanfu’s decision inevitably met with some opposition. Wang Chuanfu said confidently, "I am determined to do it, and I believe it can be done. Judging from the road BYD has traveled, more than 98% of my decisions are correct! " "I will work as a car for the rest of my life!"

Shortly after purchasing Qinchuan Automobile, Wang Chuanfu asked his men to collect several boxes of books on automobile technology for him in bookstores in Xi ‘an and Beijing. When Wang Chuanfu invited car design expert Lian Yubo to join BYD, Lian Yubo asked, "Do you know anything about cars?"

Wang Chuanfu honestly replied, "I like cars. I have read hundreds of books."

At the beginning of BYD’s transformation, it was sung down by the capital market and its stock was badly sold. Wang Chuanfu once promised fund managers that entering the car "will bring the company 30 million profits and the production and sales of 30,000 cars one year later". As a matter of fact, in the first two years of BYD Auto, it only spent a lot of money to build a "Fleur" model.

BYD’s First Model-"Fowler"

"Fowler" is basically BYD’s "behind closed doors" product, and the dealers can’t laugh and cry when they look at the "four unlike" in front of them, so the sales volume will naturally not be ideal. In 2005, BYD’s annual report showed that BYD sold only 15,993 cars, with a loss of 91.3 million RMB.

How to build a good car in a short time? BYD adopts reverse research and development. The so-called reverse research and development is to disassemble mature cars, learn from the advantages of other people’s products and develop their own products in reverse. This is more time-saving than saving R&D funds from 0 R&D..

In 2005, BYD launched the first car that really opened the market for BYD-"F3". Even Wang Chuanfu was surprised. In 2006, Wang Chuanfu said, "The current hot sale is completely unexpected. At first, I thought it would be more satisfactory to sell 2,000 units a month. However, according to the current sales capacity, we can walk 10,000 units a month. " Why can "F3" succeed? Because F3 was almost a replica of the best-selling car Toyota Corolla at that time, and the price of F3 was only half of the former.

BYD F3, a replica of Toyota Corolla

Like making batteries, BYD has almost completely produced its own products from production line to automobile parts assembly. At that time, BYD workers said that except for glass and tires, everything on the car was made by BYD itself; It seems that BYD, who has only been in the business for two years, has accomplished an impossible task, which has greatly saved the manufacturing cost and formed a market advantage.

In 2006, BYD quickly launched F3e, an iron-lithium electric vehicle, based on F3 platform. The motor, reducer, battery components and control system of F3e are all developed and produced by BYD. Although the F3e electric vehicle was not successful at that time, it still showed Wang Chuanfu the advantages of electrification. BYD concentrated its R&D efforts on the research and development of its first-generation hybrid technology DM module. At this point, Wang Chuanfu began an all-round attack on fuel vehicles, electric vehicles and automobiles.

Today, BYD has almost become an all-round player. We can produce 2.0T in-cylinder direct injection, dual-clutch DM plug-in module that can be compared with Toyota Prius, and a three-electric technology platform including battery manufacturing, etc. In the "China Automobile Technology Development Report" released in December 2017, BYD’s patent technology is ranked first among mainland automobile enterprises.

Zero Run: Self-research+Self-creation

Can BYD’s "all self-produced" model still work today?

Lingpao Jinhua base welding workshop

"All car companies with a long history will eventually go to the road of" self-research "and" self-made ",and zero running is only the first to make the right choice." Zhu Jiangming said. Unlike the internet, zero running is low-key and crazy. In the 40 months since the establishment of Zero Run Automobile, we have carried out the values of "technology is king" of science and engineering men, and "the foundation for IT people to build cars-insisting on independent research and development of core technologies", which makes us seem to see the shadow of BYD in that year.

Independent research and development of automatic driving system

Different from BYD’s generation of car-making forces more than a decade ago, the focus of automobile development is on automobile mechanical technology. Vehicle design; Nowadays, the new trend of automobile electrification and intelligence has put forward new topics for the new generation of car makers.

"50%-60% of electric vehicles are actually related to electricity, and the composition of electricity is not necessarily less than that of machinery. The underlying technology will have a large number of electrical components to cooperate and interact. For the next generation of automotive hardware, especially the underlying electronic and electrical architecture technology, zero running based on Dahua technology background is completely advantageous. " Zhu Jiangming explained.

"Zero Run is the second vehicle manufacturer in the world with complete independent research and development capabilities for smart electric vehicles." Zhu Jiangming said confidently.

Different from the situation that other manufacturers rely on, Zero Run benefits from the technical advantages of Dahua Co., Ltd., and the cameras, sensors, AI autopilot chips, core software and algorithms involved in technology have been independently developed. At present, the zero-run car has achieved L2.5-level automatic driving, which can support L3-level remote upgrade. In 2020, it is planned that all models of zero-run cars will achieve L3 level through software upgrade, and in 2021, L4/L5 automatic driving test will be carried out in a small scale. After 2025, it will reach the L4/L5 level of mass production.

Comparison Table of Intelligent Driving Assist Function between Zero Run S01 and Competing Vehicles

What is the relationship between the chips in the lowest layer of intelligent vehicles? What is the embedded algorithm? Zhu Jiangming and Dahua, who have been dealing with electrical architecture technology for 20 years, have taken a fancy to the development opportunities of automobile intelligence and electrification, which is also the advantage of zero-running into the electric vehicle market. In addition, more importantly, the core technology of domestic intelligent networked automotive technology is missing, and Zero Run wants to fill the gap in automotive smart chips and intelligent algorithms. Zero-run car is jointly developing AI autopilot chip-Lingxin 01 with Dahua Co., Ltd. According to the relevant personnel of Zero Run, Lingxin 01 will have the ability of deep autonomous learning, and its computing power will reach the mainstream level in the industry, while supporting multi-chip flexible combination. At present, Lingxin 01 has entered the stage of integration verification, and it is expected to carry out real vehicle testing in the second quarter of next year.

Self-developed body platform

Different from BYD’s reverse research and development, Zero Run claimed that it had developed three body platforms-T-Platform, S-Platform and C-Platform from the beginning. The Zero Run S01 is the first mass production model based on S-Platform.

S01 is based on the design of electric vehicle platform, and the components of the whole vehicle, such as body, chassis, powertrain and battery pack, are all designed independently by zero-run. S01 curb weight is only 1240 kg, and the battery module accounts for 80% of the vehicle width. In this numerical performance, Tesla is 78%, while the average value of the electric vehicle industry is 60%. Its body-in-white weighs only 215 kg, accounting for 17% of the curb weight, while the average value of the body-in-white of electric vehicles is 20~25%.

Zero Run S01 Body-in-White

Platform S is designed with a toughened cage structure around the protection of the passenger compartment to ensure that the passenger compartment has sufficient rigidity and strength. The platform expansibility was also considered in the early stage of research and development, and the architecture can be extended from the current S01 two-door four-seat to five-door cars and models. S01 body-in-white roof adopts embracing laser welding technology to optimize the solder joints; The car body adopts a large number of processes such as thermoforming and rolling, and the proportion of thermoforming and high-strength steel is over 70%. Important anti-collision paths such as A-pillar /B-pillar/door anti-collision beam and front cabin are thermoformed, and the tensile strength reaches 1300Mpa；. The inner and outer doorsills are rolled, and the tensile strength reaches 1180Mpa.

Self-developed "Three Electricity" System

"Hercules" electric drive assembly

As the core three-electricity technology of electric vehicles, zero-running is all independently developed except batteries. Zero-run S01 electric drive is code-named "Hercules". Zero-run is fully developed forward, and the lightweight design scheme of "three in one" of motor, controller and reducer and "five in one" of motor controller is adopted.

Hercules is divided into an upper part and a lower part. The upper part is a "five-in-one" motor controller, which is divided into an upper case and a lower case.
Case) section. The upper box part is DCDC (vehicle power supply), MCU (motor controller) and PDU (high voltage distribution module), and the lower box part is VCU (vehicle controller) and OBC (on-board charger). The lower part is the driving motor and reducer. The upper part and the lower part are connected by a flexible fixed damping mechanism to form a "three-in-one" system.

This set of electric drive assembly has completed the accelerated life test of 500,000 kilometers, and it is also the first one in China to complete 120,000 continuous peak power start and peak power energy recovery braking cycle life tests. At present, it has mass production capacity. Compared with the traditional design with the same performance, "Hercules" reduces the weight by 30% and the volume by 40%, and the overall mass is only 91kg, but it still achieves the maximum power of 125kw and the peak torque of 250Nm； as the electric drive assembly. The highest efficiency of the system reaches 93.6%, and the high efficiency ratio exceeds BMW i3 by 94.49%.

Comparison Table of Motor Efficiency and Electric Control Parameters between Zero Run S01 and Competing Vehicles

After the electric drive assembly, we are looking at the battery pack of S01. The power battery PACK of a zero-run car is all independently developed except the battery cells, which is "the highest degree of independent research and development of battery packs in domestic automakers except BYD, including modules, PACK, BMS hardware and software". Due to the integrated thermal management scheme of cold and heat, the charging and discharging efficiency of the system reaches 97.7%, and the discharging efficiency can still reach 92.5% in the area of -15 degrees. The four-in-one shunt is used for current detection, which makes the SOC accuracy reach 3%; Adopt single cell bipolar double insurance to reduce the risk of thermal runaway diffusion; The battery box shell adopts integrated aluminum casting process, which reduces the total weight of the box by 40%.

Comparison Table of Battery Pack Parameters between Zero Run S01 and Competing Vehicles

Although Zhu Jiangming thinks that Zero Run wants to be Huawei in the automobile industry, as far as the current measures of Zero Run are concerned, they are more like taking the old road of BYD. Zhu Jiangming may not be as fanatical as Wang Chuanfu, but the values of "science man" and "technology is king" will make them reach the same goal by different routes.

S01, the first production car with zero running.

Is it reliable for "science man" to build a car? Judging from the successful example of BYD, the hard-core ones are very reliable. However, it is not enough to drill only in technology. It is indispensable to do a good job in "humanity" and "feelings" of automobiles, and "science and technology men" also need to open their arms and embrace the world.

BYD’s success is not only due to its tireless innovation, cost reduction, hard battle, "reverse development", its ability to appeal to consumers, but also its necessity to open the market. In the past year or two, BYD’s "Dynasty Series" has sold well, not only because of the three-electric technology, 2.0T engine, dual-clutch gearbox and DM hybrid, but also because of Wolfgang’s dragon face. BYD has gone a long way from a technical expert to a product expert, and it is still on the road.

Nowadays, in terms of intelligence and electrification, traditional car companies at home and abroad have begun to display their technical reserves and launch wonderful products. It’s a long way to go to the technical master. Let’s see if he can beat his opponent. (End)

1905 movie network news Mayday’s latest film masterpiece was released on May 24, and the box office has exceeded 40 million, setting a new record for Mayday movies! "Life Unlimited Company" is still in the release, which makes happiness and touching extend infinitely.

　

Unlimited overtime of life company audience: I will also go to see Mayday in June!

No one is always twenty years old, but there are always people who are twenty years old. Mayday, a 22-year-old group, accompanied the fans to grow up with the most youthful music and adhered to the agreement of "being 20 years old forever". This obsession with youth attracted countless audiences to punch in at the cinema. Everyone brushed, brushed and brushed indefinitely, and actively participated in this infinite grand carnival with the most infinite enthusiasm. The cinemas all over the country changed into "concert scenes" every second, and the audience lit up their flashlights, waved light sticks, and danced, cheered and cried along with the songs of Mayday. This is an unprecedented viewing experience for all, and this is also the audience and Mayday.

On major social platforms and ticketing platforms, the audience left an emotional message: "The whole movie is full of emotion and energy. See you next time in the blue sea!" "Those songs that have long been familiar have flown through time and space and pierced their hearts, bringing fresh feelings." Countless tears filled my eyes, countless times I swallowed them. Talking about the memories with Mayday, many viewers recalled their youth: "Stubborn is a song of Class Three in Senior High School. Those years were the wealth of my life, and I miss the people who struggled together." "The graduation season with" Cheers "is very uncomfortable, and graduation is almost ten years!" "In a blink of an eye, the MV will cry every time you watch it." "It is memory, youth, laughter and tears, no regrets!" This may is about to pass, and in the next June, May Day is still waiting for you!

Life is limited, but there are infinite ways to write your autobiography. All viewers will unlock more comprehensive and surprising eggs from the special edition theme video while they are still wanting more after watching the movie!

What options do you have within the budget of 80,000 yuan?

You may like a Chanel CF handbag or Vacheron Constantin’s men’s watches, but please note that under such a budget, you can only buy their second-hand styles. Or, if you are a TV fan, 80,000 yuan may give you an 85-inch 8K Sony TV.

However, these gorgeous but slightly flashy items are not what I recommend.

What is the reason for it Because under the same budget, you can easily have a new and outstanding version of Volkswagen, which was launched on April 1. This model is not only practical, but also cost-effective. What’s more worth mentioning is that the LaVida family’s preferential policy of fully subsidizing the purchase tax in a limited time makes this classic A-class car easily enter your home at a price of less than 80,000 yuan.

　　Dual clutch gearbox, a once controversial but booming species. Twenty years ago, the dual-clutch gearbox was a rare animal. At that time, it was mainly used in the field of racing, which was far from consumers. Today, dual clutch has become a force that can not be ignored in the field of automatic transmission, and more and more new cars have begun to join this camp. In the process of popularization of dual-clutch gearbox, Volkswagen is an important promoter and practitioner, and many people’s cognition of dual-clutch begins with the letter "DSG".

　　Looking AT the product line of Volkswagen Group in China, it is not difficult to find that the dual clutch has occupied more than half of the country, and the limelight has far overshadowed AT or CVT gearboxes. At the media communication meeting held a few days ago, Aika Automobile communicated with the staff of Volkswagen College, discussed the development history and product layout of Volkswagen dual clutch technology, and obtained the latest news of electrified gearbox.

　　Volkswagen dual clutch family

　　The history of dual clutch gearbox can be traced back to the first half of last century. In 1939, Adolphe Kégresse, a Frenchman, put forward the technical concept of dual clutch, but the pessimistic economic environment at that time hindered the implementation of this idea. Rudolph Franke, a German, was the first to apply for the patent of dual-clutch gearbox in 1940, and carried out experiments on trucks, but it was not put into mass production in the end. It was not until the 1980s that the dual clutch gearbox emerged in the field of racing and entered the mass production considerations of some car companies. The large-scale promotion of dual clutch should start from the beginning of this century, and the contribution made by Volkswagen Group can never be ignored.

　　In the late 1990s, Volkswagen began to cooperate with Borg Warner on the mass production of dual-clutch gearboxes. In 2002, Volkswagen launched its first production car Golf R32 equipped with dual-clutch gearbox, and the Audi TT 3.2L model equipped with the same powertrain also went to the market the following year. Subsequently, Volkswagen gradually covered the dual clutch to golf, Touran and other models, and began to promote it on a large scale in 2007.

　　The original intention of the development of dual clutch gearbox is to combine the high efficiency of manual gearbox with the convenience of automatic gearbox. In order to achieve this goal, the dual-clutch gearbox adopts a similar mechanical structure to that of a manual gearbox, and realizes rapid shift connection through two clutches. At present, the dual clutch gearbox has appeared in most models of Volkswagen Group in China. Volkswagen brand calls it DSG direct shift gearbox, while Audi brand names it S tronic.

　　Among the above gearboxes, DQ200 is the only one with dry clutch. Although the torque limit of DQ200 is not high, it is enough to meet the needs of small-displacement turbocharged engines. Almost all the transverse 1.2T and 1.4T models of Volkswagen Group are using this gearbox. As the originator of DSG mass production, DQ250 was gradually eliminated and replaced by a 7-speed gearbox that paid more attention to fuel economy. DL series vertical dual clutch gearboxes are more common in Audi models, among which DL382 and DL501 are relatively common, while DL800 is a "high-end product" for sports cars with mid-engines.

　　Evolution from DQ380 to DQ381

　　If DQ200 is an excellent partner of EA211, then DQ380/DQ381 is a tacit partner of EA888. Since entering the era of EA888 Gen3, Volkswagen has used DQ380/DQ381 7-speed dual-clutch gearbox to replace DQ250 6-speed dual-clutch gearbox on a large scale in China, and soon the European market has followed suit. Both the front and rear gearboxes adopt wet clutches, and the main purpose of increasing gears is to improve fuel economy and cope with increasingly stringent emission regulations.

　　DQ381 has taken a series of measures to reduce friction loss. The drive shaft and differential are equipped with low-friction bearings, and low-friction oil seals and low-viscosity transmission oil are used. DQ380 and DQ500 use mechanical gearbox oil pump, which consumes a lot of energy and cannot provide oil pressure continuously when the engine is stopped. DQ381 is equipped with mechanical oil pump and electronic oil pump at the same time, which reduces energy consumption on the one hand and improves the application scope and comfort of start-stop system on the other. Of course, TCU logic has also been upgraded, which is closer to consumers’ usage habits.

　　Analysis of electrified gearbox

　　In the mass product matrix, electrified gearboxes are divided into two camps: hybrid and pure electric. In China market, Volkswagen’s plug-in hybrid (PHEV) vehicles only use hybrid dual-clutch gearbox, while 48V light hybrid vehicles still use traditional dual-clutch gearbox. The DQ400e hybrid dual clutch gearbox adopts wet structure, which can bear the comprehensive torque of 400Nm, which is suitable for the high torque characteristics of PHEV system.

　　Compared with the traditional dual-clutch gearbox, the core change of DQ400e is the addition of motor and its related components. Because the motor is added to one side of the input shaft, the length of the DQ400e gearbox is increased, which increases the difficulty of spatial arrangement of the transverse power system. In order to control the size of the gearbox, the engineer sacrificed the seventh gear and adopted the sixth gear scheme. DQ400e is equipped with plug-in products such as Magotan GTE, Tanyue GTE and Tiguan L PHEV. With the promotion of Volkswagen electrification strategy, this gearbox will appear in more models.

　　Volkswagen is not a leader in the field of pure electric vehicles (BEV), but the menacing MEB platform still puts great pressure on many competing products. It is expected that by the end of this year, the ID brand products based on MEB platform will be made in China, and the new car will use APP310 power motor. The author was lucky enough to see the APP310 in kind at the communication meeting, but due to confidentiality reasons, I can’t show pictures to readers for the time being. It can be revealed that APP310 not only can provide stronger power output, but also has a more exquisite structural design, and the thickness of its electronic control device is reduced by more than half compared with APP290.

　　Editor’s comment:The development of dual clutch in China was not smooth sailing, and various stories made it controversial, but the market finally proved the existence value of dual clutch. Today, environmental protection is becoming more and more important, and the dual clutch has also derived a hybrid version, which is compatible with the motor with a compact structure. The future will eventually belong to a single-speed gearbox, and the exquisite APP310 makes people have unlimited expectations for the electric age of Volkswagen.
