Designing wheel hub bearings that reduce friction torque is an important measure to reduce fuel consumption in automobiles. Bearing seals account for a large proportion of friction torque, so improving seal design and reducing friction torque can significantly improve the performance of wheel hub bearings. By using a new type of low friction grease, the stirring resistance of grease during rotation can be significantly reduced. In addition, the geometric shape of the sealing lip of the wheel hub bearing oil seal and the condition of the sliding surface also have a significant impact on the magnitude of friction. In addition, adding concave convex treatment to the sliding surface of the sealing lip and applying low viscosity lubricating grease specifically for the sealing lip can also reduce the frictional resistance of the sealing lip
Basic information
| The first generation of hub bearings |
Mainly double row angular contact ball bearings and tapered roller bearings, the installation process is simplified by pre-set preload and built-in sealing rings |
| second generation hub bearing |
On the basis of the first generation, the assembly parts are reduced, and the design of fixing nuts and flanges makes the installation more convenient |
| third generation hub bearing unit |
integrates the ABS sensor, and the inner and outer flanges are fixed to the rim and the steering knuckle respectively for higher precision integration and connection. |
The surface of quenched products is free of oxidation and decarburization, the product surface is smooth, the metallographic structure is ideal, the hardness is uniform, it can reduce the grinding allowance, improve work efficiency, and significantly improve the service life of bearings, up to 2-5 times. The unique cold rolling and expansion technology of the bearing ring makes the metal structure of the bearing ring material denser, the metal flow lines more reasonable, greatly improving the strength of the bearing ring and extending the service life of the bearing.
