The bearings for automobile wheels are composed of two sets of tapered roller bearings or ball bearings, and the installation, oiling, sealing and clearance adjustment of the bearings are carried out in the automobile production line. This structure makes it difficult to assemble, costly, and unreliable in automobile production plants, and the bearings need to be cleaned, oiled and adjusted when the car is maintained at the repair point.
The hub bearing unit is developed on the basis of standard Angular Contact Ball Bearings and tapered roller bearings, which integrates the two sets of bearings, which has good assembly performance, can omit clearance adjustment, light weight, compact structure, large load capacity, can be pre-loaded with grease for sealed bearings, omitted external hub seals and free from maintenance, etc., has been widely used in cars, and has a tendency to gradually expand its application in trucks.
In the process of use, it is affected by axial load, shock load and radial centrifugal force when rotating at high speed, in addition, because the fork thrust and the reaction force of the separation lever are not in the same straight line, a torsional moment is also formed. The clutch Release Bearing has poor working conditions, intermittently rotates at high speed and bears high-speed friction, high temperature, poor lubrication conditions, and no cooling conditions.
