摘要 随着当前世界汽车技术的不断进步，人们生活水平的提高对汽车的安全性、操控性、舒适性和经济性等需求的提高。汽车的各大组成部分的维护与常见故障的诊断也显得日益重要。传动系是汽车发动机与驱动轮之间的动力传递装置。做为汽车的重要组成部分，并且直接影响到汽车的动力性和经济性。它应保证汽车具有在各种行驶条件下所必需的牵引力、车速，以及保证牵引力与车速之间协调变化等功能，使汽车具有良好的动力性和燃油经济性；还应保证汽车能倒车，以及左、右驱动轮能适应差速要求，并使动力传递能格局需要而平稳地结合或彻底、迅速地分离。 关键词：离合器、变速器、万向节传动轴、 驱动桥、主减速器、差速器、 半轴、驱动车轮 Abstract With the continuous progress of Automotive Technology in the world, peoples living standards improve on vehicle safety, handling, comfortable and economic needs to improve. The major part of the diagnosis of automobile maintenance and common fault are also becoming increasingly important. Transmission system is the engine and the drive wheels to transmit power between devices.as an important part of the vehicle, and directly affects the dynamic performance and fuel economy. It should guarantee that the vehic
