As one of the important conferences in the field of automotive transmission technology and an important publishing platform for market development, the fourth GRC transmission technology seminar was held on June 14-15, 2012 in Wujiang, Jiangsu.
2015 automatic assembly rate will exceed manual transmission
To meet the low-carbon, high-efficiency, easy-to-maneuver, and driving comfort requirements, various types of automatic transmissions such as AT, AMT, CVT, and DCT have won the favor of their respective consumer groups in the terminal market in recent years. Dr. Wu Zhixin, director of the electric vehicle research and development center of China Automotive Technology and Research Center, predicts that the automatic transmission will enter a period of sustained growth of high speed rigidity in the next few years, with a compound annual growth rate of more than 20%, and the proportion of new vehicle loading will increase from 35% to the end of 2015. 50% or even higher.
Huang Fangqing, director of power system prediction from HIS Automotive Division, analyzed the company's model and also believes that the domestic new car automatic transmission assembly rate will exceed the manual transmission in 2014 or 2015. He also pointed out that the third phase of the fuel consumption limit requirements for domestic passenger cars to be implemented, as opposed to the main engine, such as turbocharged direct injection, diesel direct injection, variable timing and engine friction reduction The fuel-saving effects of technologies such as start-stop, and dry DCT, AMT, CVT, and wet DCT in automatic transmissions have greater energy-saving capabilities.
Domestic companies should focus on breakthroughs
Compared with the domestic research and development of the engine, the automatic transmission also embodies the assembly of the automotive core technology. The research and development time in China is relatively late. According to Shi Xiaohui, director of the Chongqing Auto Parts and Testing Technology Key Laboratory and president of the Chongqing University of Technology, the Chinese auto industry’s actual weakest project is the automatic transmission. Although there is a gap between the manual transmission and the advanced level in foreign countries, the automatic transmission is not only farther apart. And it is not chasing chase. There are still problems. It has greatly affected the development of self-owned brands.
Shi Xiaohui said that at present, the research and development of China's automatic transmissions is far from the industry. From this perspective, it is too late for foreign transmissions to enter China. He said that the current main issue of automatic transmissions is how to meet the development issues. Cooperation with foreign countries is very important at this point. Similar to the aforementioned two guests, Shi Xiaohui's point is: Most Chinese cars will be equipped with automatic transmissions in the future.
In the face of technical difficulties in the hardware and software fields such as hydraulic systems, various valve bodies, steel belts, and control strategies, Wu Zhixin believes that the difficulties reflect the problems of engineering technology and require companies to calm down and use long-lasting perseverance to cope with it. He pointed out that companies need development ideas for strategic platforms, and that the methods of imitating and plagiarizing will only disrupt their own plans and will not become larger companies.
Huang Fangqing believes that the domestic manufacturers are in the process of production and technology selection of automatic transmissions. He pointed out that if companies can't concentrate on their own advantageous resources, and rationally plan according to their own strategies, models, and related technologies, what they end up with is not necessarily a mature automatic transmission, and it is likely that they will receive a dual effort and time. loss.
