A torsion beam rear axle is disclosed in the invention, and comprises a main beam and longitudinal arms, the longitudinal arms are welded to the two ends of the main beam, the section of the main beam is in a V shape, a stabilizing rod is installed in the main beam, the two ends of the stabilizing rod are connected with the main beam and the longitudinal arms through fixing plates respectively, and connecting plates are welded between the main beam and the longitudinal arms; an L-shaped connecting plate is welded between each longitudinal arm and the main beam, the weak link of the main beam and the longitudinal arms is transferred to the welding position of a connecting plate from the mutual welding position, and the welding area is increased, so that stress distribution is uniform, and stress concentration is not likely to happen; and fixing plates are welded to the two ends of the stabilizing rod, the fixing plates are welded to the main beam and the longitudinal arms on the two sides respectively, and the buffering performance of the torsion beam rear axle is improved while the connection reliability of the stabilizer bar is improved.
本发明公开了一种扭力梁后桥,包括主梁和纵臂,所述纵臂焊接在所述主梁两端,所述主梁截面为V型,所述主梁内安装有稳定杆,所述稳定杆两端通过固定板分别与所述主梁和纵臂连接,所述主梁和所述纵臂之间焊接有连接板;通过在纵臂和主梁之间焊接L型的连接板,将主梁与纵臂的薄弱环节由相互焊接位置转移至连接板的焊接位置,通过增大焊接的面积,使得应力分布均匀,不易发生应力集中;通过在稳定杆两端焊接固定板,通过固定板分别与主梁和两侧纵臂焊接,在提高稳定杆的连接可靠性的同时,提高扭力梁后桥的缓冲性能。
