Future Development of China's transmission technology - transmission, technology, automobiles - Hardware Industry
Auto transmission is very important to a configuration, the car's handling, comfort and fuel economy have played a very important role, which accounted for 7% of the cost of automobile manufacturing. As China's automotive consumer awareness of the rise of the automobile, the transmission has started to affect consumer behavior. In the past 10 years focused on research and development of our engine technology, transmission will most likely be hot the next 10 years research and development. The transmission will become the development trend of concern to hot.
A global scale, several major automatic transmission is AMT (automated manual), AT (automatic), CVT (continuously variable) and DCT (dual clutch transmission), they have their own advantages and disadvantages. Energy saving effect of AT worse, but the comfort is good, component reliability, a long history of its production, use a wider area. CVT for small cars, AMT when the shift will be brief interruptions, comfort worse. DCT combined with manual transmission and automatic transmission, fuel economy, comfort, it is evolved from the traditional manual transmission, now represent the highest transmission technology.
The world's largest manufacturer of Germany's ZF manual transmission, the company predicts that by 2012 cars will be sold in North America only 6% of a manual transmission. Europe and the United States where there are very different. Have institutions predict that by 2013, Europe 52% of the vehicle or a manual transmission, equipped with automatic and manual transmission will account for 10%, with stepless transmission will account for 2%, with double-clutch transmission will account for 16%. Europeans advocate energy saving, environmental protection, like the opening of small cars, more pro-gaze of manual transmission fuel economy. Transmission in the Japanese market, CVT's market share According to Absolute advantage.
In China, According to a survey manual transmission in 2007 accounting for 74% of the market, accounting for a larger market share. From 2002 to 2007 automatic transmission market share from 9% to 26%, GlobalInsight company expects 2012 automatic transmission will account for 33% of the share, while the proportion of passenger cars automatic transmission may reach 44% . From 2002-2006, the female users increased from 20.3% to 30.9%, while the automatic transmission easy to use features like user groups popular among women. Another concern in the consumer survey, most auto parts, the first is the airbag, the second is the automatic transmission of the transmission, automatic transmission market in China is very optimistic. While the energy-saving manual transmission, economy and driving fun also determine its irreplaceable.
Currently, domestic enterprises on the transmission of these techniques have different levels of development, which, CVT's industrialization and scientific research leading the way, AMT is accelerating industrialization. Recently, the National Development and Reform Commission, driven by domestic vehicle for more than 10 companies and the United States Borg Warner has set up a company called "the Union Industrial Co., Ltd." The joint venture to develop dual-clutch transmission (hereinafter referred to as "DCT") of key technologies. Global master DCT technology company is Borg Warner and Schaeffler company.
Transmission for the Chinese market trends, GlobalInsight of Asia technology analyst Dr. Duan Chengwu Some described their opinions:
1, in the short term, manual transmission still occupy a major share of the automatic transmission will have more room for growth.
Second, given the complexity of the Chinese market, the long term development of transmission is not a single style trend, no one form of transmission will become the final winner.
3, in the Chinese market, from technical support, the current market share, and these devices in terms of AMT and LPG, AUTOE and gasoline, CVTE and hybrid, and the DCT and diesel are similar to it.
4, in the long run, China's local enterprises should pay more attention to DCT this product, because it has very good prospects.
