文档介绍：I 摘要随着汽车工业的发展,车用变速器的设计趋势是增大其传递功率与重量之比,并要求其具有更小的尺寸和良好的性能。本设计在给定发动机输出转矩、转速及最高车速、最大爬坡度等条件下,着重对变速器齿轮的结构参数、轴的结构尺寸等进行设计计算;并对变速器的传动方案和结构形式进行设计;同时对操纵机构和同步器的结构进行设计;从而提高汽车的整体性能。关键词: 变速器齿轮轴同步器 II Abstract Along with the development of the automobile industry,the trend of car transmission designing is to increase its transmission power and decrese its weight,and hope have smaller size and excellent performance. The design based on the FAW-Volkswagen pany , In conditions that knowing the engine output torque,speed of engine and maximum speed of vehicles, maximum degree, focus on the designing of transmission gear structural parameters, axis geometry putation; as well as the transmission and drive program structure design; Meanwhile on the structure ponents to manipulation and synchronous design; thereby enhancing the overall performance of cars.
