The reasons for the failure of the steering rack

19-05-2022

The reasons for the failure of the steering rack are:

1. The steering rack is faulty. Through inspection, if it is found that the steering rack assist oil pressure is low, it means that the steering rack is the cause of the heavy steering. At this time, professional manufacturers should be invited to repair. Generally speaking, most of the failures of the steering rack are due to the damage of the piston, the cylinder barrel, or the damage of the sealing ring on the piston, which causes the two cavities of the piston to be connected, so that the booster pressure cannot be effectively established

2. The booster pump is faulty. When it is judged through the test that the pump pressure of the booster pump cannot reach the standard value, it is obviously related to the heavy direction. First, check whether the meshing surface of the flow control valve and the valve seat and the steel ball of the safety valve are not tightly closed

3. The oil return filter in the oil storage tank is blocked. The oil return filter in the oil storage tank is not maintained or replaced for a long time, which will cause blockage, make the circulation of the booster oil not smooth, and cause the back pressure of the oil return to increase, which will also make the direction heavy.
