1 主离合器系统液压系统(图1)常见故障是结合、分离动作不灵,主要原因及排除方法如下: (1) 液压泵供油不足,造成压力上不去,使液压推力减小,不能使离合器正常结合、分离,且伴有较强的噪声。原因是主离合器壳内油位太低,使泵吸空,供油不足。只要向主离合器壳内加足液压油即可解决。(2) 安全阀过早打开。一般情况下,安全阀的开启压力应是3.92MPa。但由于弹簧过软,压力不足就开启了,不能形成足够的推力
1 main clutch system hydraulic system (Figure 1) common fault is a combination of separation action is not working, the main reason and troubleshooting are as follows: (1) insufficient supply of hydraulic pump, resulting in increased pressure to reduce the hydraulic thrust can not be Clutch normal combination, separation, and accompanied by strong noise. The reason is the main clutch oil level is too low shell, so that the pump suction empty, insufficient oil supply. Just add enough hydraulic oil to the main clutch housing. (2) The safety valve opens prematurely. Under normal circumstances, the relief valve opening pressure should be 3.92MPa. However, due to the spring is too soft, the pressure is insufficient to open, can not form enough thrust
