摘    要:自动变速器是现代汽车上一个重要的动力传递总成,对提高汽车的动力性和驾驶舒适性具有重要作用。文章介绍了目前汽车上应用的电控机械式自动变速器(AMT)、液力机械自动变速器(AT)、无级自动变速器(CVT)及双离合自动变速器(DCT),指出AMT适用于商用车和公交车,AT将大量应用于6挡以上的中高级车,CVT适用于排量在3L以下及混合动力车,DCT可广泛应用于各种车型.

关 键 词:自动变速器  电子控制  动力传递  自主研发

Modern Automotive Automatic Transmission Technology and its Application
Abstract:Automatic transmission is an important power assembly in modern automobiles. And it plays an important role in improving power performance and driving comfort. The automated mechanical transmission (AMT), hydraulic mechanical automatic transmission (AT), continuously variable transmission (CVT) and dual clutch transmission (DCT) is introduced. It is pointed that AMT is applied in commercial vehicles and buses; AT will be used in medium-grade vehicles and top-grade vehicles(6 gear or more); CVT is applied in less than 3L displacement and hybrid engine vehicles; and DCT can be widely used in all kinds of automobiles.
Keywords:Automatic transmission  Electronic control  Power transmission  Independent research and development
