"Automatic Transmission 2010 China imports amounted to 4.0 billion, the market growth of over 35%; 2010 Chinese brand passenger cars loaded automatic transmission for less than 10%, almost 100% dependent on imports." This is not long ago in held by the Shanghai Society of Automotive Engineers of China's "2011 International Seminar on Advanced Automotive Automatic Transmission", the statement referred to a representative of the Chinese automotive transmission market situation.

    In fact, the automatic transmission market conditions, while not satisfactory, but due to fuel consumption and the increasingly stringent emission regulations, the Chinese auto market, the requirements of the automatic transmission does not relax, in the past to 4AT products for the mainstream has largely met relevant laws and regulations and people can not drive the demand for low cost, low fuel consumption, more gear, high shift quality, durable and reliable, mature technology, a vast number of consumers in recent years, the desire for an ideal automatic transmission.

    The face of the needs of ordinary consumers, domestic manufacturers of technology is what kind of situation? In this seminar, reporters learned, FAW and SAIC began several years ago led to DCT automatic transmission research and development. In this regard, the FAW Group Deputy Chief Engineer and Chief Technology Center Director Dr. Li Jun introduced in the speech, FAW passenger car brands already planning a number of automatic transmission product platform, which AMT A00-class product platform for passenger cars , DT product platform for the A0-and A-level passenger cars, two DCT product platform, respectively B-and C-level for passenger cars.

    After pressure testing, calibration bench performance, parking system test, NVH test, pour the oil test, lubrication test, the vehicle on the standard, and a series of vehicle performance calibration and development, bench life test, calibration and vehicle matching bench After calibration, FAW several performance automatic transmission products, placed in front of people. Among them, Li Jun a special presentation for the A-Class 6DT-200 platforms. 6DT-200 through the chain drive connecting the two single-stage wet clutch of three-axis dual-clutch gearbox, no sleeve, the difficulty of processing is low, the equivalent of a low-cost dual-clutch transmission product solutions. Currently, 6DT-200 of the three products for the 5-speed and 6-speed, input torque, respectively 150,170 and 200 Nm of axial dimensions were only 325,347 and 353 mm, weight of only 65,67, and 70 kg respectively, . Compared with the existing 6AT products, 6DT-200 in the axial size and weight has advantages, and 1.4 l direct injection turbocharged engine matched to achieve, the stop (Start-Stop) basis functions on conditions in the NEDC cycle to achieve 147 g / km of low carbon dioxide emissions.

    Shanghai Automotive Co., Ltd. Technical Center Director Mr. Fang Weirong transmission Speaking of SAIC, introduced automatic transmission product development, SAIC has been in volume production and R & D products are included in the AMT, wet DCT, DCT and dry EDU power transmission products such as flooding, respectively, for A0 ~ C-class passenger cars and medium and small SUV. Which, AMT products are cost-effective, energy saving and environmental protection, maintenance and low cost advantages. SAIC product strategy as part of automatic transmission, AMT has a common batch of new equipment in Shanghai Sail sedan, and will continue to expand to SAIC MG3 own brand products and other products. The other two DCT products, DCT360 wet dual clutch transmission project started in 2006, has entered the later stage of production preparation, will soon put into production this year, and equipment brands in the SAIC Roewe and MG models; 2009 start The DCT250 dry dual clutch transmission projects, which were in August 2010 with the General Motors Corporation signed a joint development agreement in the future the two sides will share the intellectual property rights.

    EDU SAIC is developing electric drive automatic transmission products, using advanced transmission and motor control technology, coupled with HCU and clutch shift control, can improve fuel economy, emissions targets, while improving the dynamic and has a good change block comfort, the future will be equipped with its own brand passenger cars in the SAIC Roewe plug-in plug-in hybrid vehicles strong, over 50% saving can be realized, production in 2012.
