In recent years, with innovative features of modern broadcasting technology, competitive contests, diverse, innovative technology of automatic transmission in the development of the global automotive industry is a wonderful Marketin Landschaft.AT past 20 years, the global automotive automatic transmission to the AT technology, products, changing market rapidly, despite its complex structure, size, quality too much weight, fuel economy and prices ever higher, maintenance costs , etc. are subject to the AMT, CVT, DCT and other advanced automatic transmission a serious challenge, but the reliability of automatic transmission and natural functioning of the market is still too general acknowledged. To improve the inherent lack of AT, especially on fuel consumption and comfort to improve gradually from 3 gearbox, 4-course development with 5-speeds. For each additional forward, it is of reasonable size are likely to increase, quality is linked to erhöhen.Im 2001, the German company ZF introduced the first rear wheel drive six-speed 6HP26 AT type, the first use these facilities, the type 6HP26 5HP24 6-speed AT model than the previous generation 5-speed AT was reduced by 30% of the parts, quality and reduction of 12%, performance 600Nm of torque, weighs only 85kg, size is also 50mm shorter than the previous acceleration performance and fuel economy has also improved significantly. Since then, a subsidiary of Aisin AW Toyota, Nissan unit Jatco companies have started a 6-speed AT. Mercedes-Benz Motor Company in 2003, seven-speed 7G-Tronic AT type introduced. General Motors and Ford Motor Company will not transfer technology, reduce competition, need to catch up in 2003, an unprecedented collaboration and cooperation, joint development of six-speed Aisin AW AT.2006 introduced the world’s first eight-speed Tiptronic smart electronic control ECT-i, 2007 5 Nian Yue ZF has announced that it has successfully developed a new 8-speed plans on the market before 2008, and said, fuel economy Eight speed, and now 6 six-speed AT can reduce% from the original 5-speed of about 14% compared to the reduction of werden.1998 GM and Shanghai Automotive Group, a joint venture Shanghai General Motors Company, the production of 4-speed AT Pudong in 1999 while Honda Automobile and Dongfeng Motor Corporation, a joint venture Dongfeng Honda Engine Co., Ltd. Guangzhou, the production of four-speed and five-speed AT; June 2004 Nian ZF joint venture with Shanghai Automotive Group in Shanghai companies ZF 5HP Shanghai Anting-19 production standard 5-speed AT was created and began in 2006 product type 6HP 6-speed AT, 2004 Nian 11 , a joint venture of Japanese Aisin AW with China FAW Group Corporation, Tianjin, Ada automatic transmission, co-production six-speed AT, 2006 Nian Yue 3 Honda in China, Foshan, Nanhai, Guangdong Province, to establish wholly-owned Honda Auto Parts Manufacturing Co., Ltd., plans 240,000 automatic transmissions in 2006, with Getrag Ford close cooperative relationship with the founding of the Jiangxi Jiangling Motors Getrag to produce transport company wants cars with the AMT and produzieren . Allerdings MT objectively pointed out, the new 6AT, 7AT 8AT only in the field of car emissions of premium luxury show its advantages in the automotive market, an ordinary and small cars, and no use in this area, the traditional progressively more advanced CVT and DCT Trends.CVT alternative market group Bosch Netherlands Van Doorne’s CVT gearbox is a steel manufacturers and suppliers, a belt CVT is the one of the most important, while innovation in business Van Doom CVT push-belt use its patented technology to protect the privileges and monopoly in the world. The first company band generation seven-speed CVT has been hit 200 kW, 400 Nm of torque from the 20th Century Kraftübertragung.Das in the late 80s, the success of CVT in Japan, and gradually especially in Jatco company, formed a predecessor post-training, CVT-type spectra of different issues, all this has vigorously promoted the cause of the rapid development of CVT in Japan. Currently, Nissan Japan, Mitsubishi, Toyota, Fuji Heavy Industries Ltd. and other automakers the choice of models on their own, and actively proceed with the CVT transmission with Nissan X-CVT Jatco Company TRONIC fitted the couple already qualified maximum of 350Nm, and intends to further grow the company in 2007 Belastbarkeit.Jatco China, Guangzhou Science City, the establishment of a special production of cars for the precursor of the single company with the band-type CVT, production annual 14 million units, the company private in May 2007 was planned established in 2009, officially began operations genommen.Luk 2007 Shanghai Science and Technology Day said provided for the A8 sedan AU -di, a pair of continuously variable transmission wear new 450nm have been developed and are available in the second half. In recent years, 80 years of experience in the attitude of the industry, Japan’s JTEKT Corporation has announced global automotive manufacturers began to accelerate the transition from traditional development pattern of the United States of CVT be included in a contest teeth steel manufacturing efficient and silent chain. JTEKT Corporation in May 2007 and the Netherlands pinion Industry (Dutch business companies Gear Chain Industrial BV, has signed called GCI), a highly efficient CVT with a steel chain, a manufacturing agreement to exclusively license the company JTEKT planning in 2008 on the market, and in 2012 a turnover of 100 billion yen. Is reported to take steel chain J-IC high torque with a metal band was twice as large as the transmission capacity of the belt today limits the type of metal torque CVT 400 nm, while the steel chain J-IC, the possible range torque transfer has twice the band, supposedly, steel string J-IC, the unique structure of steel chain, compared to today, we can significantly reduce the steel chain and sprocket engagement, when the impact energy, pollution, noise reduction. Equipped with a steel J-channel IC CVT CVT can also more economical than the previous 4% -5%, may be the cause of CVT on the market more attractive, the CVT range of applications in the vehicle to expansion even more. J-IC industry will wait and see the future of the steel chain which Marktleistung.DCT MarketEuropäische companies like VW, ZF, GETRAG, Luk, Ricardo, Mag-neti Marrelli, GIF, etc. to maintain mechanical automatic transmission as North American, Japanese companies are harder, and has notable successes in recent years. Today, in a variety of cars, is the application of the AMT, SMG, DCT (DSG) on the most successful companies in Europe. Some gear manufacturers in Europe is a “dual-clutch automatic transmission with DCT is growing rapidly,” the anzugeben. Nach opinion show a large number of experiments with the conventional automatic level compared to the DCT wet with AT compared to 15% higher energy efficiency is more economical DCT DCT-Nasse even above 15%. Dry and wet is the future of technology’s most important DCT can not only effectively reduce fuel consumption, but also build for the hybrid powertrain, a good platform to further reduce fuel consumption. In addition, the hybrid technology also apply to enter the era of fuel cells, the company Getrag focused on developing hybrid technology and variable speed equipment, recently announced a partnership with Getrag-Bosch hybrid propulsion systems in areas DCT.9. February 2007, Getrag Corporation and Daimler – Chrysler Corporation signed a Memorandum of Understanding in North America by Getrag Corporation Daimler – Chrysler Corporation have developed and produced CSD. Getrag Corporate expansion plans on the market DCT global effort is expected by 2015 to reach the exit 2 of Getrag DCT 4 million units or more, if the global production of about 550 million DCT Einheiten.Im June 2007, Volkswagen announced that the latest version of the DCT-DQ200 type 7-speed to improve efficiency and performance, with a pair of dry clutch transmission with double clutch 6-speed home to replace wet , its compact size, the length of only 369mm, the quality can be used b
y 79 kg, a variety of vehicle models. 7-speed DCT production should be completed in late 2007 sein.BorgWarner United States (BorgWarner-ER) is the global production and supply of DCT with a known technology and products company, is the largest support team DCT Volkswagen factory. China’s Shanghai Automotive Gear Factory is the Borg Warner DualTronic products, the first five partners sein.Allerdings works DCT development costs and a huge investment in new equipment if it is not enough power, the CSD is not a very easy thing to do, even if certain market risks are changing. Power through without interruption, and Ze-roShift Technology AMT automatic transmission electron mechanical AMT has already broken transmission “broken” lethal weaknesses, Ze-roShifit clutch with a single dry plate, switching time to zero, the able to pass without interruption, this new technology in Europe, the birth of the AMT, mechanical efficiency, fuel consumption, emissions targets, the degree of comfort, especially in the cost reported more higher than the international market is the best-selling CVT and DCT, the DCT is the CVT, and has launched a challenge. In August 2002, the company founded in July 2003 ZeroShifi -2005 years in January, Zeroshift technology development, which Completed in February 2005 announced the first vehicle with an automatic walk test in September 2005 the company has provided its Zeroshift Zeroshift technology in manual transmission shifting device based on the successful implementation of 0ms time moving smoothly automatic road test results and makes the novel Branche.Dieser Zeroshift AMT benefits: (1) moving during the time difference is equal to zero, to transfer power without interruption, and (2) that further The use of single dry clutch can significantly reduce product costs, reduce the transmission quality and ensure that technically reducing the transmission of energy loss within the organization so that mechanical efficiency significantly improved, (3) conversion of parts of the original manual and the components of the increase in the more traditional components, the manufacture of light roShift Ze-force is the program that he, the transmission traditional manual is very close, but replaced by a part of the body gear synchronous simultaneous dual-slider (4). Zeroshift AMT technology, a wide range of applications, whether mini-cars, small engine displacement and traveler or a variety of vehicles, regardless of the vehicle’s power, torque, size, can so long as the original vehicle with a manual transmission, compatible applications and the automotive industry is also of the opinion mit.Einige that the potential market ZeroShifit than any other emerging technology transfer because technology transfer Zeroshift can anticipate all the different models are used, and the world can be offered, already in use, after-sales catalog is still in selling different models. Projections, should get zero Zeroshift increase of emerging technologies in its entirety to the Chinese automotive industry and vehicle driving affects young industry. In the automatic transmission technology, the rapid development of Today a diverse, the Chinese auto industry will strengthen cooperation with national and international transmission of the communication and exchange of product development for the transmission line of the Chinese automotive and control, as more qualified, or a little more.
