Abstract
The braking system is the most important system in car. If the brakes fail, the result can be disastrous. brakes are actually energy conversion devices, which convert the kinetic energy of the vehicle into thermal energy .when stepping on the brakes, the drivers commands a stopping force ten times as powerful as the force that puts the car in motion. the braking system can exert thousands of pounds of pressure on each of the four brakes. The disc brake is called the small dish type brake, this kind of brake radiates quickly, the weight light, the structure simple, the adjustment is convenient, specially when high load the performance is good, applies the brake the effect to be stable, moreover did not fear the spate attack, under the winter and the bad state of roads the driving, the disc type applies the brake compared to the drum type to apply the brake to stop easily in the short time the vehicle. On some disc brake disc has also opened many eyelets, accelerates to ventilate the radiation, enhances the brake efficiency. The principle of the design to the brake system. Synthesize the consideration of the effect to the brake system, the stability of the effect to the brake system, the simple and convenient of the brake cleft adjusting, the size and quantity of the brake system, the same of the brake system and so on to design the product. In this design, adhere to synchronously the coefficient selects by examinations, affect factor selects of the brake system. The calculation of the brake moment, and the selects of the important parts of the brake system , check the whole design at last. Keywords：brake system , disc brake,Synchronous coefficient

要
汽车制动系统是汽车各个系统中最为重要的。如果制动系统失灵，那么结果将会是毁 灭性的。制动器实际上是一个能量转化装置，这种转化实际上是把汽车的动能转换为汽车 的热能挥发出去，当制动器制动时，驱动程序来命令十倍于以往的力来使汽车停止下来。 制动系统可以发挥上千磅的压力来分配给四个制动器。 盘式制动器又称为碟式制动器，这种制动器散热快、重量轻、构造简单、调整方便， 特别是高负载时耐高温性能好，制动效果稳定，而且不怕泥水侵袭，在冬季和恶劣路况下 行车，盘式制动比鼓式制动更容易在较短的时间内令车停下。有些盘式制动器的制动盘上 还开了许多小孔，加速通风散热，提高制动效率。由制动器设计的一般原则，综合考虑制 动效能、制动效能稳定性、制动间隙调整简便性、制动器的尺寸和质量及噪声等诸多因素 百度文库计本产品。在设计中涉及到同步系数的选取、制动器效能因素的选取、制动力矩的计算， 以及制动器主要元件选取，最后对设计的制动器进行校核计算。 关键词 ：制动系统，盘式制动器,同步系数
