The solution to the steering failure of the small road roller:
1. The steering wheel cannot be returned to the center by itself, and the loss of the middle part is increased.
Cause: Broken spring.
Solution: dismantle.
2. The vibration of the working pressure continues to rise, and the steering wheel cannot even be rotated.
Reason: The pin is broken or deformed, and the opening of the interlocking shaft is broken or deformed.
Solution: Replace the shifting pin and the linkage shaft, and it is forbidden to replace it with other food.
3. The reason why the steering wheel rotates at a constant speed or shakes up and down: The rotor of the motor and the coupling are installed in the opposite direction.
Solution: A tooth on the rotating shaft solves a tooth root of the positive motor rotor.
4. When the direction of the car deviates or the steering wheel is rotated, the steering hydraulic cylinder does not move or move slowly.
Reason: double buffer valve failure, torsion spring failure, or bearing steel ball stuck by foreign objects.
