The invention relates to the field of suspensions, in particular to a multi-connecting-rod rear suspension system and a suspension assembly.The multi-connecting-rod rear suspension system comprises a steering knuckle, and the steering knuckle is connected with a rear lower H-shaped arm, a rear upper arm and a rear pull rod; the rear lower H-shaped arm comprises a rear lower arm body, the rear lower H-shaped arm is connected with the auxiliary frame to form a first connecting point and a second connecting point, and the rear lower H-shaped arm is connected with the steering knuckle to form a third connecting point and a fourth connecting point; the first connecting point, the second connecting point, the third connecting point and the fourth connecting point are distributed in a staggered manner; according to the multi-connecting-rod rear suspension system, the integrity of lower connecting rods is guaranteed through the arrangement of rear lower H-shaped arms, the structural strength of the rear lower arms can be greatly improved, and in addition, the structural strength and rigidity of the suspension system can be improved by controlling the connecting positions of the rear lower H-shaped arms on an auxiliary frame and a steering knuckle.

    本发明涉及悬架领域,具体来说是一种多连杆后悬架系统及悬架总成,包括转向节,所述转向节连接有后下H型臂、后上臂以及后拉杆;所述后下H型臂包括后下臂本体,所述后下H型臂与副车架相连接形成第一连接点和第二连接点,所述后下H型臂与转向节相连接形成第三连接点和第四连接点;所述第一连接点、第二连接点、第三连接点以及第四连接点呈错位分布;本发明公开了一种多连杆后悬架系统,通过后下H型臂的设置,保证了下连杆的整体性,可以极大提高后下臂的结构强度,另外,本发明通过控制后下H型臂在副车架和转向节的连接位置,可以增加悬架系统的结构强度和刚度。
