文档介绍：摘要
汽车的设计与生产涉及到许多的领域,其独有的安全性、经济性、舒适性等众多指标,也对设计提出了更高的要求。汽车制动系统是汽车行驶的一个重要主动安全系统,其性能的好坏对汽车的行驶安全有着重要影响。随着汽车的行驶速度和路面情况复杂程度的提高,更加需要高性能,长寿命的制动系统。
鉴于制动系统的重要性,本次设计的主要内容是轿车制动器结构设计。本文从制动系的功用及设计的要求出发,依据给定的设计参数,进行了方案论证,对各种形式制动器的优缺点进行了比较后,在前盘后鼓的基础上改为前后均为盘式制动器。在此基础上选择了简单液压驱动机构和双管路系统,选用了间隙自动调节装置,采用比例阀作为制动力的调节装置。仿真结果表明,轿车制动器结构的设计保持了制动力分配系数的稳定,改善了汽车的制动稳定性,简化了汽车的制动装置,减轻了整车质量,从而提高了汽车在行驶过程中的安全性与稳定性。

ABSTRACT
Automobile design and production are involved in many fields, its unique safety, economy, comfort and so many indicators, also raised taller requirement to the design. Automobile braking system is an important vehicle active safety system, and its performance depends on car has an important influence on road safety. As the vehicle of the speed and pavement situation plex degree rise, more require high-performance, long life of brake system.
In view of the importance of brake system, the design of the main content is a transport vehicles, the brake from brake system function and design, according to the requirement of design parameters, given the parison. On all forms of brake their advantages and disadvantages are discussed, based on HouGu have in QianPan instead of before and after are disc brakes, maintain braking force distribution coefficient, improves the stability of the braking stability and simplify the automobile braking device, reduce the vehicle quality, thereby improving the car while driving in the process of security and stability. Choose a simple hydraulic driving mechanism and double pipeline system, chose clearance automatic adjusting device, proportional valve as brake force adjusting device
Keywords: brake disc, Brake wheel cylinder, Brake caliper, Braking facings formulations

1、引言
汽车制动系概述
使行驶中的汽车减速甚至停车,使下坡行驶的汽车的速度保持稳定,以及使已经停驶的汽车保持不动,这些作用统称为汽车制动。
对汽车起到制动作用的是作用在汽车上,其方向与汽车行驶方向相反的外力。作用在行驶汽车上的滚动阻力,上坡阻力,空气阻力都能对汽车起制动作用,但这外力的大小是随机的,不可控制的。因此,汽车上必须设一系列专门装置,以便驾驶员能根据道路和交通等情况,借以使外界在汽车上某些部分施加一定的力,对汽车进行一定程度的强制制动。这种可控制的对汽车进行制动的外力
