The invention relates to the technical field of multi-connecting-rod rear suspension systems, in particular to a multi-connecting-rod rear suspension system and a vehicle. In order to solve the problems that the comfort of an existing multi-connecting-rod suspension system is reduced, and the impact deformability and the anti-nodding and anti-squatting performance of a suspension are reduced, the multi-connecting-rod rear suspension system comprises a steering knuckle, a lower control arm and an integrated small connecting rod; the small integrated connecting rod is located below the lower control arm, the two ends of the small integrated connecting rod are hinged to the lower control arm and the steering knuckle respectively, and the hinge points are B1 and B2 respectively; wherein the hinge point B1 is located above the hinge point B2. The integrated small connecting rod is arranged below the lower control arm, and in the height direction of the vehicle, the hinge point B1 of the integrated small connecting rod and the lower control arm is higher than the hinge point B2 of the integrated small connecting rod and the steering knuckle, so that a structure with high braking lifting resistance and acceleration rear squatting resistance is formed between the hinge point B1 and the lower control arm; and the wheel deformability when the vehicle is subjected to longitudinal impact is improved, so that the driving comfort of the vehicle is improved.
本发明涉及多连杆后悬架系统技术领域,具体提供一种多连杆后悬架系统及车辆。为解决现有多连杆悬架系统舒适性降低以及悬架冲击退让性、抗点头后蹲性能降低的问题,本发明的多连杆后悬架系统包括转向节、下控制臂和集成小连杆;集成小连杆位于下控制臂的下方,集成小连杆的两端分别与下控制臂和转向节铰接,铰接点分别为B1和B2;其中,铰接点B1位于铰接点B2的上方。本发明通过将集成小连杆置于下控制臂以下,在车辆高度方向上,集成小连杆与下控制臂的铰接点B1高于集成小连杆与转向节的铰接点B2,以使铰接点B1与下控制臂之间形成较高的抗制动举升、抗加速后蹲性能的结构,以及提高在车辆受到纵向冲击时的车轮退让性,进而增加车辆行驶时的舒适性。
