1、 - I - 摘 要 从汽车诞生时起，车辆制动系统在车辆的安全方面就起着决定性作用。汽车的制 动系统种类很多，传统的制动系统结构型式主要有机械式、气动式、液压式、气液混 合式。液压制动技术是如今最成熟、最经济的制动技术，并应用在当前绝大多数乘用 车上。 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,便于安装像ABS那样的高级电子设备。 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

2、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。 本设计为前轴制动器采用浮动钳盘式制动器，后轴制动器为领从蹄式鼓式制动 器。制动驱动形式为液压驱动形式，前后式（式）双回路制动控制系统。 关键词关键词：汽车；制动系统；制动器；设计；真空液压 - II - ABSTRACT Born from the car, the vehicle braking system on the vehicles security plays a decisive role. The vehicle brake system have many types. The traditi

3、onal type of braking system structure mainly mechanical, pneumatic, hydraulic, gas-liquid hybrid. Now hydraulic brake technology is the most mature and most economical technology, and applied to the most cars on present. Currently, almost cars are used in friction brakes that is the drum and the dis

4、c. The main advantage of disc brakes is at high speed braking rapidly, resist heat is better than drum brakes, brake performance constant, easy to install as advanced electronic devices like ABS.The main advantage of drum brakes, brake shoe wear small, low cost, easy maintenance, because the absolut

5、e braking power of drum brakes is far higher than disc brakes ,so drum brakes are widely used for rear-wheel drive truck, but because In order to improve the braking performance and increased power brake system must be added to make it cost more, so light vehicles generally or to use front disc，rear
