ZF自动变速器传动系统分析
摘要：变速器是汽车的重要组成部分之一，它是发动机传递动力的桥梁，变速器的好坏直接影响到汽车的燃油性能、汽车行驶过程中换挡的平顺性，更是汽车稳定性的重要保障之一。传统的变速器一般为手动变速器，它是机械操作的，随着科技的进步，自动变速器的出现，像现在比较普及的AT、AMT、CVT、DSG等自动变速器，它们的出现解决的驾驶汽车时换挡的操作步骤，换挡的操作步骤被自动变速器所取代，大大减少了驾驶汽车时的工作。同时变速器的好坏也决定了汽车行驶平顺性、燃油经济性、整车稳定性等多方面，所以变速器成为汽车研究除发动机外最重要的构件，现代计算机技术的普及与发展，使得我们在研究变速器方面更加能合理优化，运用现代的计算机仿真技术，合理的优化变速器结构，使其达到我们理想要求，并在未来的汽车上我们将安装更加高效稳定的变速器。

Analysis of transmission system of ZF automatic transmission
Abstract：Transmission is one of the important parts of the automobile engine, it is a bridge to transfer power, transmission directly affects the performance of fuel cars, driving the process shift smoothness, is one of the important guarantee of the stability. General manual gearbox for a conventional gearbox, it is mechanical operation, with the progress of science and technology, automatic transmission, as it is now more popular AT, AMT, CVT, DSG automatic transmission, which appears to solve the car shift operation steps, operation steps shift is replaced by automatic transmission, greatly reduces the driving time of work. At the same time, the transmission quality also determines vehicle ride comfort, fuel economy, vehicle stability and other aspects, so the transmission become the most important component in engine research, development and popularization of modern computer technology, allows us to study the transmission more reasonable optimization, the use of computer simulation technology in modern times. Optimization of transmission structure reasonable, so as to meet the requirements of our ideals, and in the car of the future we will install the transmission more efficient and stable.
Keywords: The transmission ；efficiency of transmission .
