2. Can't get into gear after braking
Trouble phenomenon After braking, the loader (ZL40 type) suddenly cannot run. Check the variable speed pressure gauge and the pointer points to zero, but the working device and steering system work normally.
Fault analysis The loader's variable speed Control Valve is equipped with a power cut-off valve, which can realize that when the brake pedal is stepped on to brake, the gear shift clutch of the gearbox can be automatically disconnected to cut off the power transmitted to the walking part. In the non-braking state, the brake valve stem should be connected to the upper and lower oil passages under the action of the spring, and the valve stem sealing cavity is connected to the oil tank, and the pressure oil from the pressure Regulating valve enters the shift through the upper and lower oil passages. The clutch working cylinder enables the shift clutch to be engaged. If the brake valve rod is stuck or the spring cannot return, the upper and lower oil passages are blocked, the pressure oil from the pressure Regulating Valve cannot enter the shift clutch working cylinder, the shift clutch cannot be engaged, and the loader will The above phenomenon occurs. The reason for the sticking of the valve stem is generally caused by the dirty hydraulic oil or the damage of the Y-type sealing ring in the valve body; the spring cannot be returned because the spring is deformed, bent or broken.
