AMT-made heavy-duty truck production,transmission core technology is still missing
The end of 2008, China Machinery Industry Federation said Zhang Xiaoyu, executive vice president, China's auto industry has made great progress though, the product continuously improve international competitiveness, but some core technologies with foreign countries there is a big gap. Automatic transmission is one of them. Since no real industrialization, the situation is still in control of others.
Not long ago, China launched its first Taiwan CNHTC AMT standard models of heavy truck HOWO-A7, and said that he would push the AMT main models, in which the AMT before the FAW Group has also been successfully developed and, apart from in addition, many domestic enterprises AMT heavy-duty transmission has also been a long road test, which seems to imply that domestic heavy truck research and development in the automatic transmission, a new breakthrough.
AMT has become a development trend of
"As early as 2005, when we went to the European study found that 20% of the European road tractors and 30% adoption of an automatic transmission, and this percentage is still an upward trend." CNHTC a technical staff briefed reporters on Road, Thus, as people driving comfort have become increasingly demanding, automatic transmission, not only in car applications occupy a large proportion of the truck automatic transmission will also be the development trend of its transmission system.
Over the years, automatic transmission, has indeed become the top priority of the domestic auto industry research and development. While many companies have already developed before its own transmission products, and conduct a long road test, but did not own the core technology and were all stuck in the threshold of industrialization. So far the market is difficult to see the mass production of own-brand automatic transmission.
"The current AMT automatic transmission assembly line and assembly workers in training long been ready soon begin volume production." China Heavy Duty Truck Transmission Technology Department Wang, Baozhong On the production plan, told reporters, "product input post-production volume per year 30000 units. "It is understood that the face of the industrialization experience of domestic automatic transmission bottlenecks in many foreign countries hold the AMT core technology companies are making a lot of excess profits. According to industry stakeholders introduction, Hunan, a Special Purpose Vehicle Purchasing a German company the cost of AMT is more than 20 million yuan each, but the same products, the company supplies other manufacturers offer only one in Europe 6000 ~ 7000 euros.
View of this, to speed up its own brand automatic transmission production in order to self-sufficiency, and has become an important issue facing the auto business is one of the FAW, China's heavy truck and other enterprises in this field progress in breaking the transmission manufacturing international brands business-to block China's enterprises of great significance.
Learned from China's heavy truck, heavy truck this year will be the main push AMT models. In addition, the FAW Group, there are a few more models have been delivered using the AMT. It is understood that Shaanxi Fast Auto Drive, big teeth, Qi and other heavy gear transmission companies road test AMT has also been a long time, about the market. "If there is no accident, then the domestic heavy truck market this year, there will be a large number of models equipped with AMT debut, the domestic heavy truck automatic transmission will truly realize industrialization, and even can be said that China-made heavy-duty truck then entered the era automatic shift." Industry analyzed.
"Independent walking difficulties" remain
It is understood that a number of domestic enterprises in the automatic transmission, supporting the development process have accepted the "foreign aid." Yuchai diesel engine in the development of new company and accept the help of the German FEV, FAW Wuxi Diesel has developed AoWei AVL helps, Hang made a developed country by the British Ricardo machine, Denso, Japan, the Netherlands TNO testing center to help and so on. Despite the acceptance of "foreign aid" in a way that helps Chinese enterprises break through technical barriers, but it also brought a lot of disadvantages for the enterprise, resulting in foreign enterprises make profits not only from the vehicle, but the import component parts, technology transfer fees also get huge profits. It is understood that large multinational R & D cost is generally a percentage of sales revenue of 4% ~ 5%, some even as high as 8%, but the Chinese are mostly accounted for only 2% to 3%.
"Although the AMT is just in ordinary manual transmission based on the installation of an electronic control system, using a computer to replace the person to shift, but its most difficult step leading to Kaner is the electronic control system development." CNHTC Technology Liu Wei, director of Development Center, said, "So in addressing the electronic control systems development this problem, we have chosen the joint development with foreign design companies. by foreign partners provide us with gearbox control unit platform, heavy truck technicians according to Chinese The traffic and the use of the environment, to modify and improve procedures. "
Thus, China's heavy truck while the success of AMT's R & D has an important significance, but still not free from "external force", from R & D to mass production, there is not have their own core technology, can get rid of these complementary businesses "embarrassed" also deposit there are many questions. The Shaanxi Fast Auto Drive, big teeth, teeth, etc. Qi highly in the industry are looking for heavy-duty transmission business from the core technology can also be controlled by others to be concerned about the situation. The lead organization in the State Development and Reform Commission set up under the R & D institutions - the fat Lian Industry Co., Ltd., FAW, SAIC, Dongfeng, China more than 10 enterprises are involved, a joint venture to contribute to development of automatic transmission of the key technologies. Although this make a lot of people in the trade a bit agitated, but the hair Union Industrial Co., Ltd. has also been with BorgWarner joint venture in hand to cooperate, which confirms the industry consortium for the emergence of this technology is likely to more than just a piece of brand, multi-path of one or more of the introduction of a joint venture platform, only guess.
"Set up in the real purpose should be issued together, through the joint development of core technology from a foreign get the current point of view, does not seem to get a good result." Network president, CHEN Wen-kai, said K-Swiss car. Beijing University of Aeronautics and Astronautics School of Traffic Science and Engineering, Xu Xiangyang, vice president also believes that the Borg Warner whether the core technology to domestic firms is unknown. Vehicle business market for technology lessons should be learned. If it is not the core technology is still controlled by BorgWarner dual-clutch module production, then most of the profits, or are Borg Warner acquisition.
View of this, whether it is China's heavy truck is still made in the newly established Union, China's automatic transmission, independent research and development, from the core technology controlled by others it seems the situation is still a long way to go.
