The invention provides a torsion beam assembly and a vehicle, the torsion beam assembly comprises a torsion beam body, the torsion beam body comprises a cross beam and longitudinal arms, the longitudinal arms are connected to the two ends of the cross beam, and lower dead centers are arranged at the connecting positions of the longitudinal arms and the cross beam; the lining is connected with the longitudinal arm, one end of the lining is provided with first end face rubber and second end face rubber, the first end face rubber is arranged on the side, away from the cross beam, of the lining, and the second end face rubber is arranged on the side, away from the cross beam, of the lining; the upper end of the buffer block is arranged on the vehicle body, the lower end of the buffer block is a free end, and a buffer space is formed between the free end and the lower dead center; when the torsion beam body jumps upwards, the buffering space is gradually reduced. And under the condition that the buffering distance is zero, the free end is in contact with the lower dead center. The technical problems that the axial rigidity of a cylindrical bush is low, and the lateral rigidity of a torsion beam is low are solved.

    本发明提供了一种扭力梁总成和车辆,扭力梁总成包括:扭力梁本体,扭力梁本体包括:横梁和纵臂,纵臂连接至横梁的两端,且纵臂和横梁的连接位置设有下止点;衬套,衬套连接纵臂,衬套的一端设有第一端面橡胶和第二端面橡胶,第一端面橡胶设于衬套远离横梁的一侧,第二端面橡胶设于衬套远靠近横梁的一侧;缓冲块,缓冲块的上端设置于车身上,缓冲块的下端为自由端,自由端和下止点之间形成缓冲间距;其中,当扭力梁本体上跳时,缓冲间距逐渐减小;在缓冲间距为零的情况下,自由端和下止点接触。本发明解决圆柱形衬套轴向刚度较低,扭力梁侧向刚度较低的技术问题。
