摘 要

在汽车工业100多年的发展史中，动力传动系的技术进步一直处于一个举足轻重的地位。车辆行驶性能的好坏，不仅取决于发动机，而且在很大程度上依赖于变速器及变速器与发动机的匹配。为了有效的提高车辆的动力性和燃油经济性，便产生了适应时代需求的自动变速技术。随着电子技术和自动控制技术的发展，自动变速技术已经越来越成熟，自动变速器的种类和形式也日益多样化。计算机与换档变速技术的结合，有力的推动了汽车工业的发展。

自动变速器的维护，由定期维护与日常维护组成。为了在维护的过程尽量的解决问题，对自动变速器应有充足的了解，而本课题则是主要介绍了典型的自动变速器以及维修维护的主要方向以及办法，因此本课题的研究具有重要的现实意义。

Abstract

Abstract：In the automobile industry history of the development of more than 100 years, ：the powertrain of the technological advances have been cited in a foot .Level position. The quality of performance vehicles, not only depends on the engine, but relies heavily on .In the transmission and matching of transmission and engine. In order to effectively improve vehicle dynamics and fuel economy, Would have had to adapt to the requirements of the times of the automatic transmission technology. With the electronic technology and automation technology, Automatic transmission technology has become increasingly mature, the type of automatic transmission and the increasing diversification of forms. Computer With variable-speed transmission technology, a powerful impetus to the development of the automobile industry. The maintenance of automatic transmission, from regular maintenance and routine maintenance components. In order to safeguard the process of problem-solving as much as possible on the automatic transmission should have sufficient understanding of this issue is mainly a typical automatic transmission, as well as repair and maintenance as well as the way to the main direction should be the subject of this research has important practical significance.

Key words: Torque converter; clutch; electronic control
