摘要
从汽车诞生时起,车辆制动器在车辆的安全方面就起着决定性作用。目前,汽车所用制动器几乎都是摩擦式的,可分为鼓式和盘式两大类。盘式制动器的主要优点是在高速刹车时能迅速制动,散热效果优于鼓式刹车,制动效能的恒定性好。鼓式制动器的主要优点是刹车蹄片磨损较少,成本较低,便于维修、由于鼓式制动器的绝对制动力远远高于盘式制动器,所以普遍用于后轮驱动的卡车上,故本次轻型载货汽车采用前盘后鼓式制动器。
本设计前轴采用浮动钳盘式制动器,后轴采用制动器为领从蹄式鼓式制动器。设计的主要内容包括:制动器的研究现状及意义、制动器方案的选择与分析、盘式制动器结构的设计、鼓式制动器结构的设计。

ABSTRACT
The brake has played a significant role in vehicular security since the car was born. In current, most of the brake is frictional, which concludes disc brake and drum brake. The chief advantages of disc brake are that it can apply the brake quickly in high-speed trig, that it has a better cooling function than drum trig, and that the application of the brake can have a long affection. While the chief advantages of drum brake are that trig hoof can have less abrasion and cost, and that it can be easily mended .As the drum brake has a higher drag force than disc brake, it use in rear wheel drive truck widely, due to these factions, We use before the disc brakes followed by the drum brake in this light shipment car.
The front axle of this design use before the floating disc brakes, and the rear axle use brought from the hoof type drum first chapter of the design instruction chiefly introduces the current state and the purport of brake, the second chapter tells the choice and the analysis of the brake project mostly, the following chapter describes the calculation and check of the disc brake structural design, and the last chapter introduces the calculation and check of the drum brake structural design.
Keywords: Light bills car,Disc brake ,drum brakes, Brake shoes, design.
