某型轮式装载机在日常使用中,其制动系统中的加力器经常出现内漏和外漏故障,导致整机制动性能降低或无制动,给设备的安全使用带来较大风险。1加力器工作原理图1所示为该型装载机制动系统加力器的结构示意图。制动时,踩下制动踏板,由气制动总阀出来的高压气体从进气口A进入加力器气室2,气室1内的空气由呼吸器(图1中未画出)排出,气室活塞1压缩回位弹簧3带动推杆4向右运动,进而推动液压总泵活塞10向右运动,将制动液从出油口B排出,从而使钳盘制动器的制动
A certain type of wheel loader in daily use, the brake system of the booster often leakage and leakage problems, resulting in reduced braking performance or no brake, the use of the device to bring greater safety risk. 1 booster works Figure 1 shows the structure of the loader brake system structure diagram. When braking, depressing the brake pedal, the high-pressure gas coming out of the main valve of the air brake enters the booster chamber 2 through the air inlet A, and the air in the chamber 1 is exhausted by the breathing apparatus (not shown in FIG. 1) Discharge, the gas chamber piston 1 compression return spring 3 drives the push rod 4 to the right, and then push the hydraulic master cylinder piston 10 to the right, the brake fluid discharged from the port B, so that the brake caliper brake
