汽车车制动系统设计毕业设计论文

摘要

随着社会的飞速发展，科技越来越发达，世界也变得越来越小了，造成这个现象的基本原因就是交通工具的发展和普及，尤其是汽车的应用，灵活高速的汽车给我们的生活带来了极大便利。一方面，轿车变的越来越重、动力越来越大；另一方面，人们越来越强调汽车驾乘的舒适性和安全性。因而，作为能保证汽车安全行驶的组成部分之一—制动系，有必要对它的组成构件进行设计计算。

本文系统详细的介绍了汽车制动系的结构型式及其主要构件的设计计算，阐述了制动器的两种结构型式的选择和各自的工作原理、制动系的主要参数及其选择、制动器主要零部件的结构设计和分析计算、制动驱动结构的结构型式选择与设计计算。并且通过以上的比较分析，在经济可靠的基础上选择归纳了伊兰特轿车制动系主要构件的结构与参数，予以最为合理的配置。其中重点介绍了汽车车制动系的主要构件——浮钳盘式制动器、液压双回路制动主缸的分析计算。

ABSTRACT

As the society is making great progress, scientific technology becomes more and more developed, and the world becomes smaller and smaller. The basic cause of this is the development and popularization of transportations, especially the application of automobiles, which bring great convenience to our lives. On one hand, what the car changes is heavier and heavier, motive force is greater and greater; On the other hand, people emphasize comfortableness and security that the automobile drives more and more. Therefore, as guaranteeing one of the components that the automobile goes safely--the brake system, it is necessary to carry on exhaustive designing calculation .

This text mainly introduces the structure pattern of the brake system and its designing calculation of main departments, and explains two kinds of structure patterns and choosing and one's own operation principle of the brake , main parameter of the brake system in the department and choosing, structural design and calculation of the main spare part of the brake , applying the brake urges the structure pattern of the structure to choose and design and calculate , makes the regulation device that power distributes. Through comparative analysis of the above , is it sum up Elantra apply the brake structure and parameter , department of main member to choose on the basis of the thing that economy is reliable , in order to reach and dispose best. Especially, it introduces the main member of the department of the brake system among them --Float pincers records of type brake , hydraulic pressure pairs of meeting way apply the brake analysis of master cylinder calculate with anti-lock braking system , urge slip resistance systematic theory analyse. And have checked to rubing the friction characteristic lined with slice at the end of the thesis.

Keyword: Automobile；The brake system；Disk brake；Hydraulic drive；Parking brake
