The invention discloses a twist beam suspension. The twist beam suspension comprises a cross beam, wherein longitudinal beams are symmetrically arranged at the two ends of the cross beam; the lower ends of the longitudinal beams are connected with longitudinal hub plates for mounting wheels; spring seats are fixedly mounted at the lower ends of the longitudinal beams connected with the cross beam; shock absorber mounting brackets are mounted on the longitudinal beams on the lower sides of the spring seats; the lower sides of the outer walls of the spring seats are also fixed together with the upper sides of the outer walls of the shock absorber mounting brackets through welding; and reinforcing rods are mounted on the inner side walls of the upper ends of the longitudinal beams. Through the adoption of the reinforcing rod structures, partial loads on bushings at the front ends of the longitudinal beams are shared by the reinforcing rods under conditions that a vehicle is turning, passing a pit and so on when the load is born on the suspension; therefore, the load of the suspension are shared at a plurality of points so that structural cracking risks at the mounting points of the bushings at the front sections of the longitudinal beams of the twist beam suspension are reduced. As the cross beam, the longitudinal beams, the spring seats, the shock absorber mounting brackets, the reinforcing rods, the hub plates and so on are reasonably assembled together, the maneuvering performance of the whole vehicle is effectively improved and the reliability and maneuverability of a chassis are enhanced.
