摘  要

汽车制动系的基本功用是使行驶中的汽车减速或停车，在下坡行驶的汽车的车速保持稳定以及使已停

驶的汽车在原地或坡道上驻留不动的机构。汽车制动系直接影响着汽车的安全性和停车的可靠性。随

着高速公路的迅速发展和车速的提高以及车流密度的日益增大，为了保证行驶安全、停车可靠，汽车

制动系的工作可靠性显得日益重要。也只有制动性能良好、制动系工作可靠的汽车才能充分发挥其动

力性能。
汽车的制动系是汽车行车安全的保证，许多制动法规对制动系提出了许多详细而具体的要求，这是我

们设计的出发点。
从制动系的功用及设计的要求出发，依据给定的设计参数，进行方案论证。对各种形式的制动器的优

缺点进行了比较后，选择了前盘后鼓的形式。这样既保证了较高的制动效能又有很好的稳性。

Abstract

     The automobile braking system basic function is causes in the travel the automobile

to decelerate or to stop, stabilizes as well as causes already the automobile in the

downhill travel automobile vehicle speed maintenance which stops trips in keeps the

motionless organization on in-situ or the slopeway. The automobile braking system

directly is affecting the reliability which the automobile security and stops. Increase

day by day along with the highway rapid development and the vehicle speed enhancement as

well as the stream of vehicles density, in order to guarantee the travel is safe, stops

reliably, the automobile braking system operational reliability appears day by day

importantly. Also only the braking quality to be good, the braking system work reliable

automobile can fully display its power performance.                        
The automobile braking system is the automobile traffic safety guarantee, many applied

the brake the laws and regulations to propose to the braking system many detailed and

concrete request, this was a starting point which we designed.
Embarks from the braking system function and the design request, the basis assigns the

design variable, carries on the plan proof. Has carried on the comparison after each

kind of form brake good and bad points, after has chosen the morning market the drum

form. Like this both had guaranteed higher applies the brake the potency and to have the

very good stability.
