前一时期,我单位一辆解放CA141汽车制动阀发生故障,其现象是:当气压升至0.7MPa以上时踏制动踏板,后轮无制动,但前轮制动良好.经拆检制动阀通往后轮制动气室的管路,发现气压很低,但输入管路中气压却正常,说明故障出在制动阀. 1.故障分析根据上述情况,我们对制动阀进行分解检查,但未发现异常,于是便象以往解决老解放那样首先对其平衡 The previous period, a unit of my liberation CA141 car brake valve failure, the phenomenon is: When the pressure rose to 0.7MPa above riding brake pedal, the rear wheel without braking, but the front wheel brake well. Brake valve leading to the rear wheel brake chamber of the pipeline and found that the pressure is very low, but the input line pressure is normal, indicating that the fault in the brake valve. 1. Failure Analysis According to the above situation, we brake valve Decomposition inspection, but did not find abnormalities, so as in the past to solve the old liberation as the first balance
