The vehicle is in normal running; the driver will encounter the steering wheel flutter; the front wheel shakes; the steering wheel is difficult to control when it is severe. The reason for the instability of the steering wheel is: the ball joint wear of the horizontal and straight tie rods is loose, the steering knuckle is the main The pin and the bushing are severely worn; the cooperation gap is too large, the front wheel bearing is loose; the meshing gap between the steering gear worm and the roller is too large, the upper and lower bearing gaps of the worm are too large, etc. If the low speed travels; the front wheel shake is not obvious; The front wheel sway while the speed is running; the steering wheel vibrates; in addition to the above reasons; there may be front rims, the tires are equipped with padding or innovative tires, the front beam is forbidden, the steel plate spring bolts are loose, front Bridge twists and turns and frame deformation. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Judging method: 1. One person changes the steering wheel; another person investigates under the car; if the steering wheel changes and the steering arm does not change; then the problem is turning to the organization itself; should look at the gap between the upper and lower bearing of the worm and the meshing gap between the worm and the roller, swinging left and right Steering wheel; according to the feeling, whether the meshing gap between the worm and the roller can be too large, push and pull the steering wheel up and down; whether the gap between the upper and lower bearings of the steering worm can be excessively determined by the feeling; if it is too large, it should be adjusted. Still need to cooperate with two people; if the steering arm is greatly changed; and the front wheel is not deflected; then check whether the steering arm and the horizontal tie rod can loosen; if necessary, adjust it. Then lift the front axle and push the tire by hand; Check if the gap between the knuckle king pin and the bushing is too large; can the front wheel bearing be loose? Check if the front rim can be arched. You can first erect the front wheel; put a stylus next to the rim (no stylus; you can also put the wire on the brick or wood); then change the wheel; move the stylus close to the rim; The degree of arching; usually does not exceed 3 to 5 mm; otherwise it should be proofread.

Damage to the traction motor bearing causes the traction system to be unstable. Repair the normal information and requirements of the bearing outer packaging. Select the bearing type and variety.
