Make it small
The second generation and the third generation of hub bearing structure design should be carried out finite element analysis, in order to ensure that the flange has enough rigidity while reducing its volume and weight as far as possible, the third generation of hub bearing rigidity is the inclination Angle of the hub flange relative to the outer ring flange. The integrated and miniaturized design reduces axle weight. The second-generation hub bearing reduces the weight by 180g compared with the first-generation hub bearing, while the third-generation hub bearing further reduces the weight by 120g.
Low friction moment
An important measure to reduce automobile fuel consumption is to design hub bearing with low friction torque, and the main factors affecting the friction torque of the bearing are the type of bearing and preload, bearing seal caused by a large proportion of friction torque components. Therefore, the improved sealing design can significantly improve the performance of hub bearing by reducing the friction torque. Wheel hub bearing from the first generation to the latest fourth generation, friction torque significantly gradually reduced.
