Support the front wheel and manually rotate the front wheel, you will hear an
abnormal noise. If the bearing is in use, it can be judged by the flexibility of
rotation and the sound made during rotation. The hub bearing is one of the key
parts of the automobile. Its main function is to carry weight and provide
precise guidance for the rotation of the hub. This requires it to bear not only
the axial load but also the radial load.
Automobile plane bearings are also called pressure bearings, and they are the
most common in automobile suspension types, because the suspension is
characterized by the existence of spring shock absorbers as load-bearing struts,
and this strut combined with the steering knuckle also bears the left and right
rotation fulcrum of steering. The plane bearing is placed on the top of the
shock absorber, between the spring and the top rubber of the shock absorber. It
has to withstand the up and down pressure and also be able to rotate freely. So
for suspension, this is an important part. The following Auto Bearing
Manufacturer let's learn about the failure performance of plane bearings and how
to judge the failure of plane bearings.
The reason for the damage of the plane bearing: Generally, the ball thrust
bearing is used now. The ball thrust bearing has a shortcoming, the vertical
bearing is large, and it cannot withstand the horizontal force. When the
steering wheel is turned in place, the friction between the tire and the ground,
the ground has a horizontal torque to the tire, and this torsion makes the axle
supporting the tire tilt . The force of the shaft tilt acts on the plane
bearing, causing the bearing to receive a horizontal force.
Over time, the contact surface between the ball and the bearing frame is
deformed. This deformation is irregular, which is why the rattle sound occurs.
In addition, the quality of domestic bearing materials is not good enough, and
insufficient surface treatment hardness may also be a reason. I personally feel
that the first damage is the part in the red circle. This place is the
How to judge the failure of automobile plane bearing:
1. There is an abnormal sound of "Da Da Da Da" when steering, or turning the
steering wheel in the same position or at a low speed will make a choking
2. There will be a rattling sound at a low speed steering angle, the steering
wheel will vibrate, and the direction will become heavier.
3. Tire noise becomes noticeably louder when driving
4. Abnormal noise over speed bump
5. The vehicle runs sideways
6. The steering system is damaged
7. The suspension system is damaged.
