Steering gear leaking
The main reason is the oil leakage of the upper cover (oil leakage at the small shaft connected to the ten-byte, and the dust cover at both ends of the steering gear.
Troubleshooting: Whether the high-pressure oil pipe joints are tightened, whether the joint sealing ring is aging and damaged, so as to avoid misjudgment caused by oil leakage at the high oil pipe joints.
The free stroke is too large and there is no sound
Please check and troubleshoot the following first
A. Whether the connection between the steering wheel and the steering column is loose.
Whether the connection between the B ten-byte and the steering column, and the ten-byte and the steering machine is loose.
Whether the tie rod (inner ball head) of the C direction machine is loose and whether the outer ball head is corroded.
Abnormal noise when turning is usually the mechanical part. During inspection, you can turn left and right to observe the noise part for disassembly and inspection.
The steering wheel has a serious failure
If you encounter a heavy directional landing, especially if the direction is heavy on both sides, you should find the reason from two aspects:
On the one hand, look for the reason for the mechanical part of the steering. If there is no problem with the mechanical part, then look for the reason for the steering assist.
Hydraulic steering gear failure:
Generally it is the internal cause of the steering machine (assistance failure)
In practice, the failure of turning briskly in one direction and turning heavy in the other direction often occurs. This is generally due to the leakage of the seal that is responsible for sealing the high-pressure chamber on one side.
Such as steering disc rod sealing ring, oil passage tight ring on the circumference of the piston, etc. There is also a situation that should be paid attention to, that is, the rotation is heavy, and the limit valve on one side is not tightly closed. The poorly closed may be improperly adjusted, so Most of the limit valve is in the normally open position, or the valve and the valve seat are not tightly closed. More stunned conditions are caused by the failure of the two "o"-shaped sealing rings on the limit valve.
Sometimes it happens that when turning in a certain direction, it is very light from beginning to end, and when turning in another direction, it starts to be very light. Every time you hit a certain position, the direction will suddenly become heavy. This kind of failure is generally speaking. It is due to improper adjustment of the limit valve in this direction, so that when the wheel has not reached the limit position, the limit valve opens to unload, and the direction is immediately heavy. In case of this failure, just re-cut the limit valve according to the previous section Just adjust
