通过对汽车制动系中制动器、驻车制动器、制动传动装置及制动力分配调节装置的组成,工作原理技术状况检测的分析,深入讨论汽车制动系的检测方法及其日常的维护,汽车制动系常见故障的维修。伴随着节能和清洁能源汽车的研究开发,汽车动力系统发生了很大的改变,出现了很多新的结构型式和功能形式。新型动力系统的出现也要求制动系统结构型式和功能形式发生相应的改变。 By analyzing the composition and working principle of brakes, parking brakes, brake actuators and braking force distribution devices in the automobile braking system, the paper deeply discusses the testing methods of the braking system of the automobile and its routine maintenance. Brake system maintenance of common faults. With the research and development of energy-saving and clean energy vehicles, the automobile power system has undergone great changes, and many new structural types and functional forms have emerged. The emergence of new power system also requires braking system structure and function of the corresponding changes.
