The invention discloses an independent rear suspension system of an automobile. The independent rear suspension system comprises a rear suspension body, a first auxiliary spring and a second auxiliary spring. The first auxiliary spring and the second auxiliary spring are arranged between the rear suspension main body and the vehicle body, and the upper ends are connected to the automobile body; when the wheels are in a non-jumping state, the lower end of the first auxiliary spring and the lower end of the second auxiliary spring are separated from the rear suspension body by a first preset distance and a second preset distance respectively in the vertical direction, the second preset distance is larger than the first preset distance, and the first preset distance and the second preset distance are both smaller than the limit jumping distance of the wheels. The independent rear suspension system can ensure that the automobile always has better comfort under different loads, and meets the comfort requirement of the seven-seat automobile. Besides, the structure, the arrangement form and the connection point position of the control arm assembly of the independent rear suspension system are optimally designed, the performance of the independent rear suspension system is further improved, and the arrangement space of the independent rear suspension system is reduced.

    本发明公开了一种汽车的独立后悬架系统,包括后悬架主体、第一辅助弹簧和第二辅助弹簧;第一辅助弹簧和第二辅助弹簧均布置在后悬架主体和车身之间且上端均连于车身;车轮未上跳状态下,第一辅助弹簧的下端和第二辅助弹簧的下端在垂向上分别与后悬架主体相距第一预设距离和第二预设距离,第二预设距离大于第一预设距离,且第一预设距离和第二预设距离均小于车轮的极限上跳距离。该独立后悬架系统能够保证汽车在不同载荷下始终具有较好的舒适性,满足七座汽车的舒适性需求。此外,本发明还对独立后悬架系统的控制臂组件的结构、布置形式和连接点位置进行了优化设计,进一步提升了独立后悬架系统的性能、缩小了独立后悬架系统的布置空间。
