Do you know that?/You know what? Do you know that?/You know what? In addition to Aisin domestic cars, these 8 brands of 6AT transmissions are also in use.

In China, if a car is equipped with Aisin 6AT transmission, the domestic media can directly write a press release about the test drive without even a test drive, which shows Aisin 6AT's position in China. But let's put aside the subjective impression and directly find several different models of 6AT transmission. Can you really tell which one is equipped with Aisin transmission? In fact, there are many brands of 6AT transmission, and even domestic cars are equipped with as many as 8 kinds, and their performance is different. Today, let's take a look at other brands of 6AT transmissions besides Aisin domestic cars.

ZF 6AT transmission

ZF is the first manufacturer to develop 6AT for passenger cars, and their 6AT is also a very old slave product. Its 6HP series 6AT has gone through two generations, the first generation was from 2000 to 2007, and the second generation was developed after 2007. It is the first 6AT in China that adopts Rapala strapdown mechanism. It applies technologies such as dynamic pressure balance of oil cylinder, counteracting centrifugal pressure and canceling one-way clutch. 6AT unveiled the multi-speed process of the automatic transmission of passenger cars, and also established the important position of RepalaCzech in 6AT.

However, there are not many models equipped with this transmission in China, mainly because it has not opened the gap between quality and price with Aisin, a star product. However, Aisin's marketing is very successful, so ZF did not do more homework on the 6-speed transmission, but expanded the 8AT and 9AT transmissions upward, forming a difference with Aisin.

Sara 6AT transmission

The earliest prototype of Sara 6AT transmission is Australian DSI? The 6AT gearbox was later acquired by Geely and re-developed. At that time, it was installed on a series of models such as Global Hawk and Emgrand, including the 6AT gearbox used by Borui and Job. Although this gearbox was developed by Australians, it can also be said to be the earliest homemade 6AT gearbox.

And the performance of this gearbox can only be said to be quite satisfactory, because it is DSI after all? Very early products, Geely itself has no ability to make better improvements. The high fuel consumption of the old AT gearbox was well inherited by this gearbox. Now Geely has sold 6 1% equity of DSI to Sara Group, which shows that Li Shufu is not satisfied with the performance of this gearbox.

Now Sara 6AT will not only provide Geely with some AT transmissions, but also provide some other car companies with small production. And most Geely cars have chosen to carry powershift.

Hyundai Wotai 6AT Transmission

Although Korean cars have never been world-class, most of them are independently developed. In this regard, there are really only a handful of car companies in the world that can do this. Many people don't understand modern times, and even have never heard of Paavotai, but in fact, Paavotai 6AT transmission is not worse than Aisin 6AT, because the product promotion is not recognized by domestic consumers.

Korean cars still have a special liking for Pavotai 6AT transmission, such as Sonata, Mingtu, Elantra, K3, K4, K5 and other models, which can all see the shadow of 6AT transmission. Compared with Korean cars equipped with dual clutches, the models equipped with AT transmission have good durability, high stability, clearer gears and smooth shifting.

In terms of independent brands, Great Wall, BYD and other car companies are also using modern 6AT transmissions, but the 6AT transmissions of Korean cars are all developed according to their own road conditions and matched with their own engines. Therefore, in terms of hardware matching, it is difficult for the self-owned brand models equipped with Paiwotai 6AT gearbox to achieve the same matching degree as Korean models. At the same time, I lack the relevant experience of software calibration, so the final performance is different from that of Korean models.

Bangzhi 6AT transmission

Bangzhi gearbox comes from France. 20 12 Belgian PUNCH group acquired the Strasbourg factory of general motors automatic transmission and changed its name to PUNCH? Powerglide, Chinese name is Bangzhi transmission.

Bangzhi's main product in China is 6AT transmission with vertical platform. At present, there are not many models supporting this transmission in the domestic market. The earliest match of Bangzhi 6AT gearbox was SAIC Chase D90, but with the change of D90, the gearbox was changed to ZF 8AT.

In recent years, Bangzhi's 6AT transmission has been installed on pickup trucks. One is Taku Suzuki of Isuzu, Jiangxi, which provides automatic transmission models, and the 2.5T diesel engine matches Bangzhi 6AT. The other is Changan Kaicheng F70, and its automatic transmission model will be equipped with Mitsubishi 2.4T engine and Bangzhi 6AT powertrain, which has not yet been listed. There is also a very small ZTE 20 19 Highlander pickup truck, and its diesel automatic transmission model is also a Bangzhi 6AT transmission, but it seems to have been discontinued at present.

In addition to the above models, it is very rare to carry Bangzhi 6AT. Bangzhi's 6AT transmission is mainly equipped with pickups in the domestic market, which helps some pickups in their early 654.38 million yuan to launch automatic transmissions, enriching the market.

Blue belt 6AT transmission

Chongqing Blue Belt Power Transmission Machinery Co., Ltd., formerly known as Chongqing Blue Belt Industry Co., Ltd., was established on1May 8, 996. The company's main business is the research, development, production and sales of passenger car transmission gears and housings, motorcycle transmission assemblies, main and auxiliary shaft assemblies and other parts. Simply put, it is to provide parts for automobile and motorcycle enterprises. It is a well-known enterprise in the industry. It has provided parts for Geely Automobile, Chery Automobile, Lifan and Zotye Automobile, and is also a domestic listed company.

However, its 6AT product has no accurate information to determine which model it is equipped with, so it is impossible to confirm its product characteristics at present. However, it is said that there will be three series of Landay 6AT, of which 95% shafting, clutch, hydraulic system and parts are shared, which is more compatible in production and installation. In addition, core components such as hydraulic control system and planetary transmission system are compatible with 8AT and P2 mixed architecture, which is convenient for expansion. However, it is uncertain whether this 6AT can be successfully put on the market, and the product strength will be discussed later.

Wan Liyang 6AT transmission

The transmission state of Wan Liyang's 6AT is similar to that of Lauder's 6AT, which belongs to the state of only hearing its voice but not seeing its shape. However, Wan Liyang's advantage lies in his years of experience in automatic transmission research and development. But the automatic transmission can't be sold when it is developed, especially the AT transmission. When they go public, they will face world-class competitors like Aisin. Your product can't be worse than Aisin, and the price is lower than Aisin, so consumers are willing to consider buying such products, which is why it has been difficult to make progress in the domestic AT gearbox field.

It is worth mentioning that this 6AT automatic gearbox took only 268 days from product project, product design, component development to successful prototype trial production. This is a bit too hasty. Maybe Wan Liyang just used this 6AT as a training machine.

Huatai 6AT transmission

When it comes to Huatai Automobile, many people don't know it, not to mention that Huatai Automobile has a 6AT transmission. As early as 20 14, Huatai Automobile had its own six-speed automatic transmission code 6FA38. The technology of Huatai 6AT transmission comes from ZF (ZF Group), the mainstream transmission manufacturer in the world. Since 2006, Huatai Automobile has carried out close technical cooperation with German ZF, and finally successfully developed the self-developed 6AT transmission through digestion, absorption and re-innovation of imported technology. However, with the decline of Huatai Automobile, Huatai's 6AT was gradually ignored and finally disappeared into people's field of vision.

Dongan Qifa 6AT transmission

Dongan Automobile Development (DAE)6AT transmission may be the most famous domestic 6AT transmission in the industry, and its product strength can completely reach the first-class level in the world. If China wants to come up with an AT transmission to compete with Aisin, it can only be this transmission, and this 6AT transmission is also the first product with independent intellectual property rights in China.

It is precisely because of the product strength of Dongan Automobile that Aisin, which has always been indifferent, immediately responded. On the same day, Aisin joined hands with two domestic vehicle manufacturers to set up a Japanese-funded joint venture company to produce a 6-speed automatic transmission (AT) and related spare parts in China, so as to suppress its own brand transmission, which also caused a heated discussion on automobile rights protection.

This 20 17 6AT transmission naturally gathers the strength of many experts. While maintaining a small body, the ultra-long stroke torque converter, linear proportional solenoid valve and low resistance friction technology are adopted to overcome the shortcomings of traditional AT transmission, such as low transmission efficiency and high fuel consumption. What's more commendable is that this 6AT gearbox of Dongan Automobile Company is completely designed according to its own brand engine, and it also provides a full set of software calibration services. The combination of software and hardware directly makes the performance of the final product better than that of those models that only bought Aisin hardware products, forming a corner overtaking.

summary

As a transmission mechanism, the performance of gearbox directly affects the driving performance and comfort of vehicles. It is no exaggeration to say that if a car is excellent in other aspects, but the gearbox is poor, then this car must not be called a good car. For the complicated road environment in China, the strong adaptability of AT transmission is undoubtedly the best choice, and 6AT is the mainstay, which determines the driving quality of general family cars. For a long time before, Aisin became the best choice. I hope that after reading this article, you can know more about the transmission and don't limit your eyes to a single brand.
