PAGE PAGE \* MERGEFORMAT II 摘　　要 汽车动力总成是汽车的核心部分。他的工作是将发动机功率的转换，功率有效地传递到驱动轮上和经济上适应，以满足汽车的需求。传输是一个重要的组成部分完成的动力总成的任务，而且关键部件，以确定车辆的性能之一。设计这款车的动力性，燃油经济性，可靠性和可移植性切换操作，稳定性和传输效率等的传输水平有直接的影响。随着汽车工业，汽车越来越多传动设计的发展趋势权力移交重量转移重量和需要传输具有更小的体积和良好的性能。 本文介绍了发动机的选择，程序确定的传输，传输设计，变速器同步设计，变速箱的设计。捷达在给定的发动机输出扭矩，速度和最大速度，最大爬坡能力条件。在齿轮轴等结构尺寸的设计计算的结构参数 关键词：变速器；齿轮；同步器；设计；结构 ABSTRACT Automotive Powertrain is the core of the car. His job is to convert the engine power, the power effectively transmitted to the drive wheels and economically adapt to meet the demand for cars. Power transmission is an important part of the completion of assembly mission, but the key component to determine the performance of the vehicle. Have a direct impact on the design of this cars power, fuel economy, reliability and portability switching operation, stability and transmission efficiency of the transmission level. With the auto industry, more and more cars drive design trends devolution weight and weight transfer required transmission with a smaller footprint and a good performance. This article describes the engine choice, the program determines the transmission, transmission design, transmission synchronous design, the gearbox design. Jetta at a given engine output torque, speed and the maximum speed, maximum gradeability condition.
