Due to its close proximity to the ground and high temperature brake discs and other parts, hub bearings need to adapt to a variety of complex road conditions and harsh environments. Therefore, the bearing seal must have good heat resistance, mud and sewage resistance
The third generation of wheel bearings generally use the self-locking semi-inner ring of the swaging technology. During the rolling process, an axial load is applied to the hub end with a flange to deform the semi-inner ring. Compared with the traditional nut tightening, this wheel shaft end rolling method has several advantages. For example, the third-generation hub bearing (for non-driving wheels) in Figure 2 helps reduce size and weight while reducing costs. The third-generation hub bearing (for driving wheels) in Figure 3 is pre-loaded before being assembled into the car, so the step of adjusting the position of internal components is eliminated. The third-generation wheel hub bearing adopting the rolling technology has the above advantages whether it is used for driving wheels or non-driving wheels.
The latest technology
Increasing environmental awareness around the world has prompted automakers to reduce vehicle fuel consumption to reduce their environmental impact. NSK helps automakers achieve this goal by reducing the weight, volume and frictional torque of wheel bearings.
Wheel bearings reduce axle weight by increasing integration. The second-generation hub bearing has reduced weight by 180g compared to the first-generation hub bearing, while the third-generation hub bearing has reduced weight by 120g.
3.1.2 Finite element analysis
The finite element analysis (FEM) was performed during the design of the second and third generation hub bearings to ensure that the flange is sufficiently rigid while further reducing its weight. Figure 4 is an example of the finite element analysis of HUBK. The thickness can be reduced to ensure the optimal design of the flange while maintaining the stiffness.
