Wheel Bearing Hub Assembly Kits China Suppliers Bearing design essentials

For those of you who are determined to enter the automobile industry, please pay attention. (Knock on the blackboard and highlight the key points)

When designing bearings, the following points are mainly considered:

●Interference and clearance design (mainly for first-generation bearings and second-generation bearings)

●Bearing strength/stiffness

●Bearing drag torque

●Bearing life

●Tight sealing

Wheel Bearing Hub Assembly Kits China Suppliers Bearing strength:

Because bearings must withstand very large radial and axial loads, strength is critical. Stress and strain analysis is generally performed through CAE, with a certain safety margin added.

Bearing stiffness:

If the stiffness of the bearing is very poor, it will cause the flange surface connecting the bearing and the brake disc to undergo large deformation when the bearing is subjected to lateral force, which will lead to problems such as eccentric wear of the friction plate.

Bearing drag moment:

The drag torque of the bearing is the resistance when the bearing rotates. Its size affects fuel consumption and, for new energy vehicles, the cruising range.

Wheel Bearing Hub Assembly Kits China Suppliers Bearing life:

Bearings are maintenance-free throughout the life of the vehicle, so their lifespan must be longer than the life of the vehicle. Its life calculation has a very complex calculation formula, which is also the Know-how of different parts suppliers.

Wheel Bearing Hub Assembly Kits China Suppliers Sealing:

It refers to the sealing ring that prevents external water/dust from entering the inside of the bearing, thereby affecting the lubrication of the steel ball and ultimately affecting the life of the steel ball.
