The invention relates to the technical field of automobile suspensions, in particular to a balance shaft assembly and an automobile suspension system. The balance shaft assembly comprises a balance shaft support, a flexible bush and a shaft shell, a shaft part is formed on the balance shaft support, the flexible bush is arranged on the shaft part in a sleeving mode, and the shaft shell is arranged on the flexible bush in a sleeving mode. The diameter of the outer wall of the shaft part is gradually reduced from the middle to the two ends to form a first limiting matching face, the inner diameter of the inner wall of the shaft shell is gradually reduced from the middle to the two ends to form a second limiting matching face, and a third limiting matching face matched with the first limiting matching face is formed on the inner wall of the flexible lining. And a fourth limiting matching surface matched with the second limiting matching surface is formed on the outer wall of the flexible bushing. The invention provides a balance shaft assembly and an automobile suspension system, which are used for overcoming the defects that in the existing balance shaft assembly, a composite bushing possibly has the risk of sliding along a balance shaft bracket, so that the relative position between a balance shaft shell and a steel plate spring deviates, and potential safety hazards of personnel and goods are caused.
本发明涉及汽车悬架技术领域,尤其涉及一种平衡轴总成及汽车悬架系统。平衡轴总成包括:平衡轴支架、柔性衬套和轴壳,平衡轴支架上形成有轴部,柔性衬套套设于轴部,轴壳套设于柔性衬套;轴部的外壁沿中部至两端直径逐渐减小,以形成第一限位配合面,轴壳的内壁沿中部至两端内径逐渐减小,以形成第二限位配合面,柔性衬套的内壁形成有与第一限位配合面相配合的第三限位配合面,柔性衬套的外壁形成有与第二限位配合面相配合的第四限位配合面。本发明提供一种平衡轴总成及汽车悬架系统,用以解决现有平衡轴总成中,复合衬套可能出现沿平衡轴支架滑动的风险,导致平衡轴壳和钢板弹簧之间的相对位置发生偏移,造成潜在的人员和货物安全隐患的缺陷。
