The invention provides a rear suspension pull rod and a vehicle, and belongs to the technical field of automobile suspensions.The rear suspension pull rod comprises a framework and a main spring arranged in the framework, the main spring comprises a plurality of hemispheres which are sequentially connected in the Y direction, a first vibration reduction cavity is formed in each hemisphere, a middle body is arranged between every two adjacent hemispheres, and an inner core is arranged in the middle body in a penetrating mode in the Z direction. According to the rear suspension pull rod, on the premise that the rigidity and the vibration isolation capacity of the main spring in the X direction are guaranteed, the rigidity and the vibration isolation capacity of the main spring in the Z direction can be improved, and therefore vibration of a whole vehicle is reduced.
本发明提供了一种后悬置拉杆以及车辆,属于汽车悬置技术领域,包括骨架和设于骨架内的主簧,主簧包括沿Y向依次连接的多个半球体,半球体内开设有第一减振腔室,相邻半球体之间设有中间体,中间体沿Z向贯穿设置有内芯。本发明提供的一种后悬置拉杆,在保证主簧X向刚度和隔振能力的前提下,能够提升主簧Z向的刚度和隔振能力,以降低整车的震颤。
