摘 要随着高速公路的迅速进展和车速的提高以及车流密度的日益增大,为了保证行车安全、停车可靠,汽车制动系的工作可靠性显得日益重要。本说明书主要介绍了捷达轿车制动系统的设计。首先介绍了汽车制动系统的进展、结构、分类,并通过对鼓式制动器和盘式制动器的结构及优缺点进行分析。最终确定方案采纳液压双回路前盘后鼓式制动器。除此之外,它还介绍了前后制动器、制动主缸的设计计算,主要部件的参数选择及制动管路布置形式等的设计过程。关键字:制动;鼓式制动器;盘式制动器;液压AbstractWith the rapid development of Expressway and increase the speed and traffic density increasing day by day, in order to guarantee the traffic safety, parking, automotive braking system working reliability becomes more and more important. This paper mainly introduces the design of braking system of the jetta type of car. Fist of all, braking system’s development, structure and category are shown, and according to the structures, virtues and weakness of drum brake and disc brake, analysis is done. At last, the plan adopting hydroid two-backway brake with front disc and rear drum. Besides, this paper also introduces the designing process of front brake and rear brake, braking cylinder, parameter’s choice of main components braking and channel settings.Key words: braking; brake drum; brake disc; hydroid pressure 目录摘 要.....................................................................................................................IAbstract...............................................................................................................II第 1 章 绪 论.......................................................................................................11.1 制动系统绪论...........................................................................................11.2 汽车制动系应满足如下要求:...............................................................2第 2 章 制动...
