文档介绍：摘要
汽车是现代人们生活中重要的交通工具其是由多个系统组成的,制动系统就是其中一个重要的组成部分。它既要使行驶中的汽车减速,又要保证车辆能稳定的停驻在原地不动。因此,汽车制动系对于汽车的安全行驶起着举足轻重的作用。
在本次设计中,根据已有的普通货车制动器设计。其中对制动系统的组成、制动系统主要部件的方案论证、制动力矩的计算、鼓式制动器结构参数的设计、制动器相关部件的校核、制动主缸和制动轮缸的直径工作容积的计算、制动踏板力与踏板行程的计算等方面进行了设计分析。
设计所附的多张图纸对设计的思想、制动系统的布置设计表达的非常清晰。希望在翻阅说明书的过程中能够结合图纸,这样就可以更加有效的理解设计的思想和意图。

ABSTRACT
Automobile is the important transportation tools in the modern life. It positive by many systems. The most important parts are the brake system. The system made the autocar slowdown; what’s more, the automobile is stopped steadily. There by the brake system play an important part in security steer. In the design, which based on the data of brake system used in CA1037. pose of the brake system is designed. And the main piece applied with CA1037 is demonstrated. The braking force and the parameters of drum brake’s configuration are included in this design also. What’s more, the validating of correlation parts in the brake system and the diameter of the main crock of braking and the crock applied in brake wheel are designed . Meantime , the its stroke volume are referred to The force effected the footplate when braking and the travel of footplate and so on are analyzed .
The drawings are very detail to explain the ideas of design and the disposition for the brake system . When you thumb the annotation text, you bine the drawings, which made you understand the ideas and meaning in this design effectively.
