矿用自卸汽车的载重量大都在20t以上,为了确保其行车安全而采用了脚制动与手制动双套装置。脚制动用作行车制动,手制动主要用作停车制动。由于停车排气手制动装置安全可靠,结构简单,维修方便,因此该装置被重型自卸汽车广泛采用。手制动装置和后制动器一体作用于后桥制动臂上,由驾驶室内的手动式操纵阀控制气路,供停车时使用或当车辆正在行驶,失效时作紧急制动使用。通过长期使用和维修,感到手制动存在如下缺点: ①又细又长的气路通过多个接头连接于底
Dump trucks are mostly loaded with more than 20t, in order to ensure their driving safety and the use of foot brake and hand brake double sets of devices. Foot brake is used as service brake, hand brake is mainly used as parking brake. Due to the safety and reliability of the parking exhaust hand brake device, simple structure and convenient maintenance, the device is widely used by heavy-duty dump trucks. The handbrake and the rear brake act integrally on the rear axle brake arm and are controlled by the manual pilot valve in the driver’s cab for use when parked or when the vehicle is running and in case of failure. Through long-term use and maintenance, hand brake feel the following shortcomings: ① thin and long gas through the multiple joints connected to the end
