The invention discloses a rear suspension assembly. The rear suspension assembly comprises a rear suspension, a lower support, an upper support, a first cantilever, a second cantilever and an output shaft. The rear suspension comprises a first bearing end, a damping cavity and a second bearing end, at least one oil seal ring is arranged in the damping cavity, and the situation of oil leakage caused by insufficient pressure in the midway is prevented. The invention also discloses a system for testing the damping performance of the rear suspension assembly. The system comprises a transportation structure, a clamping structure and an oscillation structure. A hinge point between the first cantilever and the lower support is K1, a hinge point between the first cantilever and the second cantilever is K2, the rear suspension is provided with an upper hinge end and a lower hinge end, one of the hinge ends is connected with the upper support, a joint point between the rear suspension and the upper support is K3, and the telescopic stroke of the rear suspension is K4. And the overall comfort of the rear suspension assembly to the mining dump truck is detected, so that the test accuracy is improved.

    本发明公开了一种后悬挂总成,后悬挂总成包括后悬挂、下支架、上支架、第一悬臂、第二悬臂和输出轴。后悬挂包括第一承载端、减震腔和第二承载端,阻尼腔内设置有至少一道油封圈,防止中途出现压力不足漏油的情况。本发明还公开了一种后悬挂总成减震性能测试系统,减震性能测试系统包括运输结构、夹持结构和震荡结构。第一悬臂与下支架之间的铰接点位为K1,第一悬臂与第二悬臂之间的铰接点为K2,所述后悬挂具有上下两个铰接端,其中一个铰接端与上支架连接,后悬挂与上支架之间的交接点为K3,后悬挂的伸缩行程为K4,通过测试多个铰接点的减震系数,检测后悬挂总成对矿用自卸车整体的舒适性,从而提高测试的精准性。
