汽车在行驶过程中,驱动后桥不仅要承受垂直地面的载荷,而且在制动与侧滑时还会受到平行地面与轴向载荷的作用。当汽车行驶工况恶劣时,其受力变得更加复杂,而这些力都是通过轮毂轴承传递的。因此,在汽车设计中,对轮毂轴承的静态强度、动态疲劳强度、抗冲击性能、使用寿命等技术指标均提出了很高的要求。而汽车轮毂轴承的装配质量在很大程度上决定了轮毂轴承的使用性能及使用寿命。以往,我公司后桥总成的装配没有考虑到轮毂轴承的压入力
The car drives the rear axle not only to bear the load of the vertical ground, but also to act in parallel to the ground and the axial load during braking and skidding. When the vehicle driving conditions worse, the force becomes more complicated, and these forces are transmitted through the hub bearing. Therefore, in automobile design, the static strength, dynamic fatigue strength, impact resistance, service life and other technical indicators of the wheel hub bearings are all set high demands. The assembly quality of automotive wheel bearings to a large extent determines the use of wheel bearings performance and service life. In the past, the assembly of the rear axle assembly of our company did not take into account the press-in force of the hub bearing
