摘要

随着汽车的发展，汽车已经成为人们必不可少的交通工具。我国买车的家庭也越来越多，人们对性能的要求也越来越高。传动系作为汽车动力传动重要部分，然而它的保养被人们视为可有可无，远没有发动机车身受人重视。其实汽车的传动系，直接关系到汽车的安全性、操控性、舒适性和经济性各种关键的性能。随着现在汽车的不断发展更新，传动系的结构也越来越复杂，自动化程度也越来越高，当然传动系也将是未来汽车发展的重要组成部分。当前努力发展汽车传动系已成为各国政府和汽车行业的共识，汽车传动系的发展已成为汽车行业的热点。因此，无论从设计、研究的观点，还是从实用角度来看，社会对传动系发展的需求会越来越大。同时，汽车传动系发展对我国汽车行业是个很好的机遇，是我国汽车行业进军世界汽车竞争行业的一个重要转折点，这也说明传动系在中国有非常大的发展空间。本文主要简单的谈论汽车传动系的故障及诊断。

ABSTRACT

Abstract

With the development of automobile, the car has become the indispensable means of transport. Buy cars in China more and more families, awareness of performance requirements are also getting higher and higher. Transmission system as an important part of automobile Powertrain, it maintenance is seen as dispensable, however, is far from engine body men. Automotive transmission system, directly linked to vehicle safety, handling, comfort and economy of critical performance. With the continuous development of the auto update now, Powertrain structure more and more complex, the degree of automation is getting higher and higher, of course, transmission will also be an important element of future vehicle development. The current efforts to develop automobile Powertrain has become the consensus of the Governments and the auto industry, automotive Powertrain Development has become a hot spot in the automotive industry. Therefore, whether from the perspective of design, research, is also from a practical point of view, the growing demand of the community for Powertrain development. At the same time, automotive Powertrain Development on China's automobile industry is a very good opportunity, is competition in China's automotive industry into the world automobile industry an important turning point, it also means that development of transmission system in China has a very large space.This article simple talk fault and diagnosis of automotive transmission systems.

Key words : transmission system; fault; diagnosis
