China has become the world's largest automobile consumption country. As one of the main assemblies that embodies the power and comfort of automobiles, the automobile transmission has become a key topic that has attracted widespread attention and discussion since the engine. Since almost all domestic manufacturers of transmissions of their own brand are started from manual transmissions, the various types of automatic transmissions used in the introduction of branded models, including AT (automatic transmission) and AMT (electronically controlled mechanical automatic transmission), are currently available in the market. CVT (continuously variable transmission), DCT (dual-clutch automatic transmission) and other products, but in terms of domestic independent brand manufacturers, the automatic transmission industry is based on a weak foundation and a single type of use, has become a major factor directly affect the marketing of independent brand models.

What type of automatic transmission should be developed by domestic independent brand manufacturers? The answer to this question seems to have long been the conclusion. Because among the many companies that journalists have come into contact with, most companies including FAW and SAIC have already demonstrated that DCT will be the most valuable product in the future. At the same time, many manufacturers have also carried out different levels of development and trial production. So, is it not the case that the development direction of China's independent enterprises in the future of automatic transmission is DCT? I am afraid it is not necessary.

Understand the changes in the selection of manufacturers from the industrial background and usage habits

Although the strategy of “giving priority to the development of AMT, CVT, timely development of DCT, and moderate production of AT” proposed by the China Association of Automobile Manufacturers and the China Gear Professional Association, it seems that the development direction of the automatic transmission industry of China’s own brand has been clearly pointed out. In the specific market environment, China’s automatic transmission industry did not follow the “established route”. In particular, it is unacceptable to ordinary consumers that although a few self-owned brand models already have automatic transmission models, there is still a long way to go before the industrialization process, regardless of whether the type or level is far from the needs of consumers.

The reporter noted that due to differences in the environment and habits of use, automatic transmissions have basically formed several relatively clear preferences in the world: North America is dominated by AT forms; although the CVT form was born in Europe, it is currently used in Japan. The most popular; many models in Europe are still in the form of manual transmission, but the latest technology DCT is the first to carry forward in continental Europe.

When the reporter interviewed the Chinese transmission industry expert on this phenomenon and was currently working at the Powertrain Research Institute of the Jianghuai Automotive Technology Center, Mr. Zhi Bainian, he explained that AT, which is dominant in the United States, has a market share of over 90%. Its historical background. Since the installation of the first AT by Odysmobile of General Motors Corporation in 1937, the United States has been using AT for a full 72 years. From the development to production, assembly, loading, use and service maintenance of the AT industry in the entire country, etc. The overall industry supporting Jackie Chan is very mature. In addition, the price of refined oil in the United States has always been one of the lowest in the world. Therefore, the use of relatively fuel-efficient AT has long been a habit in the United States.

The use of CVT is inextricably linked with the continued promotion of several major car manufacturers in Japan and the famous transmission manufacturer Jatco. At present, China has adopted the CVT model Nissan Sylphy, Hacker, Qi Jun, Tianzhu, Mitsubishi Outlander, Wing God, Honda Civic (hybrid), hippocampus happy, Southeast Ling Yue, etc., but also have a puzzle with the Japanese car.

Although many people have questioned the torque transmission, dynamic response and fuel consumption levels of CVT products, especially their core technology, the monopoly of pressure steel strips, has been criticized. However, a set of data provided by the famous CVT core component supplier Bosch Co., Ltd. shows that the Honda Fit 1.5RSC VT version introduced in Japan in 2007 was 14.0% less than the manual version; in 2007, the CVT version of the Nissan Versa 1.8SL model was introduced in the United States. The manual version saves fuel by 5.1%; the Nissan 2.5CVT version introduced in China in November 2008 saved 3.1% compared to the manual version.

For domestic companies that once had several CVs researching and developing CVT, some of them have already given up and some are in a stagnant state. Shi Wei, Manager of CVT Business Department of Bosch (China) Investment Co., Ltd. said in response to a reporter that the first thing to look for is To CVT is a mature technology, it has excellent fuel economy, and also has the potential to further reduce fuel consumption, in addition it also has a benchmark in terms of weight and size.

"The domestic automakers' choice of CVT cooperation methods and the development of CVT models are not ideal. They have not found a very suitable partner, so they have taken quite a few detours. They usually just buy a design from an original Japanese manufacturer. , and then imitating, and then research and development.After a few years they did find that the CVT technology is not so easy, not to rely on the copy to be fully able to produce their own, and now we have seen more and more domestic OEMs aware of this problem "For the crux of the domestic development of CVT, Shi Wei gave his answer.

AMT is likely to take the lead in forming industrialization

Although DCTs have been fitted to models on many models in China, and many independent brand manufacturers led by FAW and FAW, either jointly or independently, are also committed to the development of DCT, but domestic manufacturers independently develop DCTs from real ones. Commercialization seems to have some distance.

In fact, unlike the aggressiveness of DCT and CVT, AMT has appeared in many models on the domestic market in the absence of deliberate propaganda in the past year or so. It can be said that AMT is occupying A0. The class car market is also targeting the A-class market.

People concerned about the development of AMT should also note that AMT is not only rapidly popularized on small passenger vehicles, but also has a great momentum of development in the field of commercial vehicles. Heavy commercial vehicles such as Sinotruk and FAW Group have already begun trials of AMT products. In addition, several domestic commercial vehicle transmission manufacturers—Fast, Big Tooth, Reeds, and North Tooth—are also planning and developing their AMT products; among them, North Tooth's AMT products have been trial-produced in small batches. Special AMT commercial products may soon be available. AMT's inheritance of manual transmission products and manual transmission production lines has become a new force that can not be ignored in China's national conditions.

If the advantage of AMT is that the production line has less investment, material costs are small, and the finished product is quick, then from a more professional point of view, the small weight-to-torque ratio and high transmission efficiency may be the magic weapon that AMT can really survive.

Another thing that recently attracted reporters' attention is that Hunan Changfeng Automobile is developing AMT products, and its products will soon appear in Changfeng’s existing Yuling and other models.

In response, Dr. Wei Jun, Technical Director of Hunan Changfeng Automobile R&D Co., Ltd. introduced that the development of automatic transmission in China bears the brunt of industrial integration. There are four elements in industrial integration. The first is the industrial integration of vehicle applications. Under the drive of several other factors - the gear box should be industrial grade, the entire auxiliary machinery should be industrial grade, and the hardware and software of the control system should also be industrial grade. Dr. Wei Weijun deliberately emphasized that only under the industrial protection driven by the vehicle, the other three industrial-grade projects can ensure that the products developed can meet the requirements of the vehicle.

It is understood that the Changfeng AMT project has great ambitions, with 100,000 units in the first phase, 200,000 in the second phase, and 300,000 in the third phase. Dr Wei pointed out that the overall performance of Changfeng AMT products is currently the highest in the country; from a development point of view, it will cover all A-class models and a small number of B-class cars, as well as mini-cars and crossovers.

In addition to the above mentioned AMT has a good development situation, from the current market can see that more mature AT products have been transitioned from the "standard" 4AT to 5AT, 6AT; despite being criticized by many parties, Chery, BAIC, The southeast, hippocampus, Hafei and other manufacturers' own brand products still choose CVT as the main powertrain configuration during development; while DCT is currently only used in joint venture brand cars in China, but once formed a breakthrough of an independent manufacturer. After that, it will spring up like a mushroom.

Just as an old domestic manufacturer AMT manufacturer of the Jianghuai Tongyue Co., Ltd., an owner of the Qingshan Transmission Factory, said in an interview with reporters that China and the European market are similar, the biggest advantage is that the manual transmission has a strong industrial foundation and is easy to use. Forming AMT's supporting industries; but at the same time, the depth of the Chinese market is very large, and it will inevitably form a diversified product structure. Ultimately, the market will determine everything, not the type of technology to determine the market.

It is widely used in electronics, electroplating, food, machinery, chemical, laser, card making, medical and other industries. Because the source of its heat exchange is gas, it is equipped with a dedicated electric fan, so it is called "air cooling".
The air-cooled chiller is mainly used for plastics. It can accurately control the temperature of plastic forming molds to shorten the molding cycle and accelerate product setting. This series uses the principle of cold and heat exchange for cooling, which can quickly cool down and stabilize the temperature control. And not affected by environmental factors.
