　　[car home Technology] powershift, in the impression of most people, is just equivalent to a swordsman with high kung fu in martial arts novels (such as seeking defeat alone? )-The evaluation we can give is: fast, fast, very fast. Moreover, this kind of transmission is direct enough and efficient enough, and it is like a master who never drags his feet … but why is it fast? Why is it efficient? What is its control principle? Is it really advanced? Want to know the answer? You don’t have to go to Baidu. car home has already opened powershift’s coat for you here-ladies and gentlemen, look for the answers you want in front of the naked transmission.

> > > Special note: 1. This paper only dissembles the DSG gearbox objectively, and does not comment on the phenomenon.

　　2. Regarding the topic of stability and fault that users are concerned about, we will explain it for you in the following follow-up articles. There is a notice at the end of the article. Please leave a message and participate in the discussion if you have any questions or faults about the dual clutch gearbox!

　　As usual, first of all, briefly introduce the protagonist of this "dedication": Volkswagen DQ200 dual-clutch gearbox-the first Volkswagen DSG gearbox made in China.

● Get familiar with DQ200 gearbox quickly? Manual gearbox? Dual clutch gearbox?

　　Before we begin, we need to form an awareness of the dual-clutch gearbox in our consciousness. If you still don’t know what the gearbox is and how the basic manual gearbox works, we have prepared the following aperitif wine for you, please taste it first.

　　After understanding the structure of the manual gearbox, it is much simpler for us to understand the dual-clutch gearbox. In principle, the dual-clutch gearbox is equivalent to the combination of two manual gearboxes, one controls the odd gear, the other controls the even gear, and the reverse gear is queued according to the situation (in the DQ200 7-speed dual-clutch gearbox, the reverse gear is regarded as a group with the even gear). Then, one set can be added to the combination of these two manual gearboxes. Hong Gong, a well-known Volkswagen engineer in the media circle, used "two manual boxes and one set of automatic dialing" to vividly compare the principle of dual-clutch gearbox. The following video will help you to understand our metaphor more intuitively, and also help you to face the various parts that will be disassembled from DQ200 more calmly.

"『DQ200 gearbox principle demonstration video-in order to save your time, it is suggested thatAfter 1 minute and 12 seconds,Start watching "

　　With regard to the origin and evolution history of the concept of "dual clutch", we also give it to you as an appetizer. Please click the link below to see the ups and downs of the dual clutch so far.

● Actual disassembly of DQ200 transmission: three modules-two "powerful" and one "calculated"

　　Metaphor is metaphor. When we really put DQ200 in front of you, you can’t really see a product that is directly combined with "two manual gearboxes and one controller". The previous section is only for everyone to understand the principle of dual-clutch gearbox.

　　Judging from the actual structure of the gearbox, the main number of members of DQ200 powershift is still "three" (of course not MT+MT+ controller …). These three modules have different division of labor, and two of them are only responsible for "hard work". They are dual clutch modules and gearbox parts, and all they have to do is to transmit power, commonly known as "force". The third part is the "source of wisdom" of the dual-clutch gearbox-the electromechanical control module, but in fact it is both mental and physical-it can be said that it is both a director and an actor. What are the specific tasks and characteristics of these three modules? We interpret it by disassembling it.

● Dual clutch module: I have a foreign ID card!

　　Let’s get to know the dual clutch module with German ID on DQ200. Since powershift took his last name, you can imagine how important this guy is.

"The dual clutch module is provided by the Luk brand of Schaeffler, Germany."

　　The dual clutch module is simply two sets of clutches+one shell. We call the clutch near one end of the engine K1 clutch, and the clutch behind it K2 clutch. The two sets of clutches K1 and K2 have their own independent driven parts (friction plate+driven plate+shock absorber+driven hub), pressing mechanism (diaphragm spring, pressure plate) and operating mechanism (only the operating arm is mentioned here).

　　The double clutch housing, the driving disc in the middle of the housing, and the butterfly diaphragm springs and pressure plates of K1 and K2 are all "best friends" of the engine, and there is no relative rotation between them. The double clutch housing is connected with the engine flywheel and rotates synchronously with the engine, and these components are called "driving parts".

　　The diaphragm spring and pressure plate which rotate together with the clutch housing play an important role. Under the lever action of the control arm, the sleeve is pressed to deform the diaphragm spring, and the resulting deformation pushes (or pulls) the pressure plate to press the friction plate. At this time, the driven plate and the aforementioned driving part become a whole. With the synchronous rotation of the engine, after the power is obtained from the clutch, the driven plate relies on the internal spline to transfer the power to the input shaft, and the power from the engine enters the gearbox.

● What you don’t know about DQ200(1)
-The working principle of the clutch is the same as that of the manual gearbox, but it works in the opposite way!

　　Speaking of butterfly diaphragm spring, I have to say that this DQ200 dry dual clutch is very interesting in control mode and principle. It is consistent with the familiar manual gearbox principle, which also relies on extrusion and friction to realize the continuous transmission of power, and also uses the lever principle to squeeze the sleeve to deform the diaphragm spring. However, the diaphragm spring works in the opposite way to the diaphragm spring in the manual transmission clutch (see the dynamic diagram above). In the single-chip clutch structure of manual transmission, when the diaphragm spring is squeezed, the clutch pressure plate will be released and the power transmission will be interrupted; In DQ200 gearbox, the function of diaphragm spring when it is squeezed is actually to press the clutch to turn on the power! To put it bluntly, the clutch of the manual gearbox is-You give an external force, it separates,The clutch of this DQ200 dual-clutch gearbox is just the opposite.You give an external force, it will engage!The "disengaging bearing" and "disengaging lever" in the traditional clutch should be renamed as "engaging" XX here. …

● Gear box: double MT combined body

　　After the power enters the gearbox from the input shaft, it will begin to travel between gears. The gear camp in the box is very easy to divide-like two sets of manual gearboxes-two input shafts and two output shafts, and then a set of parking locking mechanism and a differential to transmit power to the wheel axle are added. In this way, you will find that the dual-clutch gearbox is actually just a few more shafts than the traditional manual gearbox. As we have previewed before, the shifting principle of DQ200 and manual gearbox is completely consistent, and the shifting fork pushes the engaging gear sleeve to complete the combination or separation of gears (shifting gears).

　　The two input shafts are respectively connected with the K1 clutch and the K2 clutch, and the internal and external coupling mode is adopted. The first input shaft is equipped with a 1357th gear, and the second input shaft is equipped with a 246R gear. When the two clutches work alternately, the power can be connected between the odd gear and the even gear. Take a closer look at the input shaft, and you will find another interesting thing. On the first input shaft, the gears corresponding to the 1357th gear are independent, while the second input shaft corresponding to the 246R gear has only two gears. The 4th gear and the 6th gear share one input shaft gear, and the 2nd gear and the R gear (reverse gear) share one input shaft gear. Perhaps the purpose of this design is to ensure that the hollow second input shaft can have enough strength and ensure the gearbox.

● What you don’t know about DQ200 gearbox (2)
-What’s the difference between the "N" gear (neutral gear) of the dual clutch gearbox and the manual gearbox?

　　Many netizens want to know the difference between the "N" gear of the dual clutch gearbox and the neutral gear of the manual gearbox. Take the DQ200 gearbox we disassembled as an example. Its logic in the "N" gear is indeed different from the "neutral" of our usual manual gearbox. Simply put,The "neutral" of the dual clutch gearbox is equivalent to the state that the manual gearbox is "engaged in 1st gear and engaged"., so that the speed will be faster when the power is engaged. Moreover, in the D-range mode, when the brake is stepped on for a long time, the clutch will also be automatically disconnected, and the gear engaging sleeve is still engaged with the 1st gear.

　　In addition to various shafts and gears, the gearbox body also has a part that we can’t ignore-the parking control module, that is, the "P" gear control mechanism of our vehicle. The parking gear is integrated on the third output shaft, coaxial with the reverse gear, and it is the only gear with internal splines (synchronized with the output shaft).

　　The parking control mechanism is the only one physically connected with the gear lever on the DQ200 gearbox (all other controls are transmitted by electrical signals). When we put the gear lever into the "P" gear, the gear lever is controlled by the cable, and the connecting ball pin is pulled to make the pawl buckle the parking gear, thus locking the output shaft and achieving the purpose of parking locking.

● Electromechanical control module, with developed "six limbs" and not simple mind.

　　The hardest part of the three is naturally the electromechanical control module, which is "both output and calculation". This way of working is simply a typical "IT migrant worker".

　　From the structural point of view, its composition is not complicated. The sensor, arithmetic/control chip, hydraulic unit and actuator are just four pieces of content, which is also a simple number. The electromechanical control module relies on these components to complete the whole process of obtaining information-judgment/decision-making-execution. Among them, the hydraulic pump and pressure storage tank composed of gear pump are the source of all power for the electromechanical control module, and if human organs are used as an analogy, this is the heart.

　　We humans move through four limbs. The electromechanical control module of DQ200 has six limbs, which control the operating arms of K1 and K2 clutches respectively, and the other four limbs are used to control the shift fork. Four independent fork control levers control five forks (six gears and reverse gears are two forks sharing a fork control lever), and it is the existence of independent control levers that makes it possible to engage adjacent gears in advance.

　　The "brain" that gives action instructions to limbs is provided by Continental, Germany. This brain judges the driving state of the vehicle and the driver’s intention through the engine speed sensor, the output shaft speed sensor and the operation made by the driver on the gearbox control lever, and shares a series of information on the CANBUS bus, such as vehicle speed, wheel speed, accelerator pedal position, steering angle sensor, lateral acceleration sensor and so on, and makes a response. Sensors located at the fork and clutch actuator always remind the German brain of the clutch that the gearbox is currently working and the gear that is currently combined. At the same time, according to the oil temperature sensor and oil pressure sensor in the electromechanical control module, whether the working state of the gearbox is normal or not can be monitored in time. We can imagine that this information processing ability is hopeful to challenge the popular dual-core smart phone …

● What you don’t know about DQ200 gearbox (3)
-even without a double clutch, it can be fast!

　　The reason why the dual clutch gearbox is fast enough is not only because it is as simple as a "dual clutch module", but also largely due to its independent shift control lever. Do you know what "independence" means? This means that even if there is no double clutch, since DQ200 adopts the design that the interval gears share a joint sleeve (as mentioned above), the joint sleeves of adjacent gears can operate independently, and theoretically, "the joint sleeves of one gear can be disengaged while the joint sleeves of adjacent gears are engaged!" Do you know what is the core system of Lamborghini’s ISR gearbox (the gearbox with a shift time of 50 milliseconds)? In fact, it is a number of forks that can be controlled independently!

"The reason why Lamborghini’s ISR gearbox dares to challenge the serial gearboxes of the previous supercars.
It is also because it adopts an independently controlled shift fork.

　　(This paragraph is purely for discussion, and fans are welcome to speak enthusiastically.) The effect of this independent control is more flexible than that of the mechanical multi-fork synchronous action mode relying on the "shift drum" of the sequential gearbox, especially in the case of "trip stop" (except for odd-numbered trip stop …), while the shift drum mechanism can quickly switch between adjacent gears by relying on the servo motor with quick response, but when multiple gears are shifted up or down (for example,

● DQ200(4 you don’t know (4)
-the gearbox needs to use two kinds of oil at the same time!

　　Most automatic gearboxes and even dual-clutch gearboxes only use one kind of oil, which not only needs to realize the functions of lubrication, heat dissipation and torque transmission, but also needs to provide the hydraulic pressure required by hydraulic control components. DQ200 dual-clutch gearbox adopts independent dual-oil circuit design, and different oils are applied in the two oil circuits. In the gearbox, the gear oil of model G052171 is used, which is consistent with the gear oil used in the domestic Volkswagen MQ250 manual gearbox, while the hydraulic oil of model G004000 is used in the electromechanical control module. The two oils can better play their own functions in their independent oil circuit circulation, so that the gearbox has better low-temperature working characteristics.

　　Moreover, the total oil consumption of DQ200 is only 2.7L (1.7L of gear oil and 1L of hydraulic oil), which is nearly half of that of traditional automatic gearbox and wet dual-clutch gearbox. Needless to say, DQ200 is a maintenance-free design, even if it needs maintenance later, it has obvious advantages in cost. (It is said that the oil consumption of DQ250 wet dual clutch gearbox is more than 6L, and the total oil consumption of DQ200 is less than half.)

● DQ200(5 you don’t know (5)
-What’s the difference between DQ200 (7-speed dry dual clutch) and DQ250(6-speed wet dual clutch)?

　　I believe everyone knows the most obvious difference between DQ200 and DQ250, that is, the difference between "wet and dry" clutches. DQ250 uses a wet clutch, and the control method of the clutch is completely different. DQ200 relies on hydraulic pressure to push the control arm and presses the clutch plate by the diaphragm spring, while the clutch engagement of DQ250 is completely controlled by hydraulic pressure. DQ250 designed with a wet clutch uses a single oil, because of its large consumption. Therefore, the oil tank is designed, and it has pressure oil filter, oil cooler and oil pump driven by crankshaft power, which DQ200 does not have.

　　In addition, due to the different number of forward gears, the 7-speed DQ200 has three output shafts, the reverse gear and the parking gear alone occupy one output shaft, while the DQ250 has only two, and the parking gear of DQ250 is integrated on the differential.

Summary:

　　After reading the disassembly article of DQ200, I believe everyone has a deeper understanding and cognition of this 7-speed dry dual-clutch gearbox.Personally, the dual clutch gearbox is not complicated in principle or structure, and the structure based on manual gearbox is the fundamental reason for its high transmission efficiency and low fuel consumption.The design idea of DQ200 dual oil circuit and dual oil is one of its highlights. The two independent oils have more advantages in functional adaptability, and the total oil consumption of 2.7L is also a figure worth showing off.

　　Of course, all advanced and fresh technologies always need to face people’s doubts and challenges, and our users still have various questions about "dual clutch". In the next article, we will answer the hot issues of gearbox reliability, price, maintenance and so on that are concerned by the majority of riders, and present more "DQ200 dual clutch gearbox you don’t know" for you.

E-cigarette products on the shelves in Los Angeles, USA. Xinhua news agency

　　Regulatory measures against e-cigarettes have been upgraded again &mdash; &mdash; Recently, the State Tobacco Monopoly Bureau and the State Administration of Market Supervision issued a circular requesting that e-cigarettes should not be sold to minors, nor should e-cigarettes be sold through the Internet, nor should e-cigarette advertisements be published through the Internet.

　　Appear in a "healthy" appearance, but become the "first cigarette" for young people to become smokers &mdash; &mdash; For some time, electronic cigarettes, which are popular all over the world, have aroused vigilance and strict control in all countries. It is urgent to include e-cigarettes in the scope of tobacco control and prevent them from spreading to minors.

　　Not "healthy and harmless"

　　"Many friends around me are smoking. It is said that e-cigarettes are healthier, so I also tried." Zi Huan (a pseudonym), a 17-year-old high school student, came into contact with e-cigarettes for the first time because of the strong recommendation of his friends. He was originally resistant to cigarettes, but now he has become a small smoker who never leaves his hand.

　　E-cigarette is a special tobacco product, which generally consists of smoking utensils and cigarette oil. At present, the mainstream electronic cigarette in China, its cigarette oil is mainly made of nicotine, and nicotine and various additives are atomized by electronic smoking sets for consumers to smoke.

　　The reporter’s investigation found that many users of e-cigarettes said that they only "entered the hand" after seeing advertisements such as "can help quit smoking" and "healthy and harmless". The Report on E-cigarette Industry Supervision (2019) issued by Tsinghua University Public Health and Technology Supervision Research Group also points out that 95% of e-cigarette retail websites associate e-cigarettes with health and cleanliness, and 89% of online stores publicize health-related benefits.

　　This is not the case. The latest "Global Tobacco Epidemic Report 2019" released by the World Health Organization pointed out that e-cigarettes are "undoubtedly harmful", not only nicotine, but also other harmful substances, and the long-term impact on health is still unclear; There is not enough evidence that e-cigarettes help to quit smoking.

　　The relevant person in charge of the State Tobacco Monopoly Bureau also said that many e-cigarette companies mislead consumers with propaganda that goes against objective facts, such as "helping to quit smoking" and "being healthy and harmless", but most e-cigarettes are very arbitrary in raw material selection, additive use, process design and quality control, and there are serious quality and safety hazards such as unsafe ingredients, cigarette oil leakage and inferior batteries.

　　Experts point out that nicotine will seriously harm the nervous system of teenagers, and e-cigarettes "wear beautiful coats" to lure teenagers to smoke, which leads them to unconsciously become addicted to cigarettes and even have a great possibility of contacting traditional cigarettes. This trend is undoubtedly worrying.

　　Aim at young people

　　Although the notice has been issued for several days, the reporter found on Taobao, JD.COM and other e-commerce platforms that there are still many brands of e-cigarettes selling normally. Although the goods are clearly marked "E-cigarettes are forbidden for minors", the purchase process is not verified and minors can easily buy them.

　　At the same time, in the e-cigarette advertisements of the above-mentioned e-commerce platforms, there are frequent pictures of young people holding and smoking e-cigarettes, accompanied by text descriptions such as "it is good to smoke" and "natural harm reduction". In addition, these advertisements also implicitly reveal that e-cigarettes are not harmful to second-hand smoke and can improve the number of conversations among young people.

　　In this regard, the aforementioned Tsinghua University’s research report also pointed out that in advertising marketing, e-cigarettes are symbolized as consumer goods of the upper class, and represent independent personality and lifestyle. In cultural products, especially TV series and MV, e-cigarettes are associated with cheerful, relaxed and enjoyable atmosphere.

　　Relevant data is worthy of vigilance. In May 2019, the survey results released by China Center for Disease Control and Prevention showed that the people who used e-cigarettes were mainly young people, 15-mdash; The use rate of e-cigarettes in the 24-year-old group is 1.5%; The main way to obtain e-cigarettes is the internet; The proportion of people who have heard of e-cigarettes, used e-cigarettes and now use them has increased.

　　The reporter found on video platforms such as bilibili that there are many e-cigarette product evaluation and fancy smoke teaching videos, and many netizens exchanged their experiences and feelings in using e-cigarettes in video comments.

　　In addition to publicity and promotion, due to the lack of standards, the quality problem of e-cigarettes is equally prominent.

　　Mao Qun An, director of the Planning Department of National Health Commission, said that many e-cigarette products contain vague labels of nicotine concentration, which may easily lead to excessive consumption by users. At the same time, there are also safety risks such as battery explosion, smoke liquid penetration, high temperature burns and so on.

　　Strengthen supervision measures

　　Last August, the State Administration of Market Supervision and the State Tobacco Monopoly Bureau jointly issued a circular explicitly prohibiting the sale of e-cigarettes to minors. The latest measures have highlighted the strict requirements for Internet sales and promotion of e-cigarettes.

　　The circular requires that all kinds of market entities should not sell e-cigarettes to minors; Enterprises or individuals producing and selling e-cigarettes are urged to close e-cigarette Internet sales websites or clients in time, e-commerce platforms close e-cigarette shops and take off e-cigarette products in time, and enterprises or individuals producing and selling e-cigarettes withdraw e-cigarette advertisements published through the Internet.

　　At present, many countries in the world have completely banned or strictly restricted the sale of e-cigarettes, and more than 40 countries or regions have explicitly legislated or officially announced the ban on the sale of e-cigarettes.

　　In China, since this year, Shenzhen, Chengdu and other places have also revised the tobacco control regulations to include e-cigarettes in the scope of tobacco control: Shenzhen has clearly expanded the concept of "smoking" to use e-cigarettes and hold other tobacco products that are ignited or heated without burning; Chengdu also explicitly includes smoking electronic cigarettes in smoking behavior, and clearly stipulates that tobacco product operators are prohibited from selling tobacco products to minors; In its rail transit passenger code, Beijing has supplemented the prohibition of smoking electronic cigarettes &hellip; &hellip;

　　After the unrestrained barbaric growth, e-cigarettes are gradually fading away from the "electronic" stunt, highlighting its "smoke" nature. Yang Tingzhong, director and professor of Tobacco Control Research Center of Zhejiang University School of Medicine, believes that e-cigarettes should not have special status, but should be included in the restrictions of ordinary tobacco, and should be restricted in advertising, marketing and consumption places.

　　In this regard, many experts in the industry have called on the state to increase the research on e-cigarettes, introduce more comprehensive and detailed regulatory measures, and strengthen the protection of minors.

　　Multi-countries strictly control electronic cigarettes

　　■ USA

　　The U.S. Centers for Disease Control and Prevention recently reported that the cumulative number of deaths from lung diseases with unknown etiology and possible association with e-cigarettes has increased to 34. At present, Massachusetts has announced that it will suspend the sale of all electronic cigarette products and electronic cigarette devices, while New York prohibits the sale of scented electronic cigarettes.

　　■ India

　　The Indian government decided that e-cigarettes have reached "popularity" among young people and issued a ban on e-cigarettes in September this year. Those who violate the ban for the first time may be fined about $1,400 or imprisoned for one year, or both, while those who violate it for many times may face up to three years’ imprisonment and a fine of nearly $7,000. The Indian government believes that e-cigarettes are harmful to health and may damage the government’s tobacco control efforts.

　　■ Japan

　　Organizers of Tokyo 2020 Olympic Games announced in February this year that this Olympic Games and Paralympic Games will bid farewell to tobacco products and its derivative substitute "e-cigarette" completely. From this summer, schools, hospitals and government agencies in Tokyo will be banned from smoking indoors; From April next year, restaurants, bars, hotels and other business places will be banned in general, and smoking areas can still be designated.

　　■ Korea

　　South Korea’s Ministry of Health and Welfare recently advised people to stop using atomized e-cigarettes and promised to determine whether the sale of e-cigarettes should be banned as soon as possible. The person in charge of the country’s health department said, "Children, teenagers, pregnant women and patients with lung diseases should never use atomized e-cigarettes." According to Korean government data, as of June this year, e-cigarettes accounted for 13% of the sales in the Korean tobacco market.

　　■ Turkey

　　Turkish President Erdogan said recently that e-cigarette enterprises are not allowed to produce in Turkey, calling on Turks to "replace cigarettes with tea". In 2013, the Turkish government banned all alcohol and tobacco products from advertising, promotion and sponsorship.
