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,但由于为了提高其制动效能而必须加制动增力系统,使其造价较高,故轻型车一般还是使用前盘后鼓式。
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。主要设计内容包括制动器结方案分析与选择、制动器主要参数的确定与计算、盘式与鼓式制动器具体结构参数设计与强度校核。

ABSTRACT
Born on, from cars in the vehicle's safety vehicle brake plays a decisive role in. , at present, the car is almost always used brake friction type, can be divided into two categories: drum and disc. The main advantage of the disc brake at high speed, braking can quickly brake cooling effect is better than that of drum brake, braking performance of constant qualitative good. The main advantages of drum brake is brake shoe pieces wear less, low cost, convenient in maintenance, because of drum brake absolute braking force far outclass disc brakes, monly used to rear wheel drive the truck on but because in order to improve its braking performance and must add braking force system, make its increased cost is higher, so small QianPan HouGu type or monly.
This design by floating p-s-n caliper disc brake, brakes is brought by axle from hoof type drum brake. Main design content including brakes "plan analysis and choose to determine the brake, main parameters and calculation, disc and drum brake specific structure parameter design and strength check.
Keywords: Light bills car,Disc brake ,drum brakes, Brake shoes, design.
