The invention provides a novel stamping and welding rear auxiliary frame which comprises an auxiliary frame body defined by a front cross beam (1), a rear cross beam (2), a left longitudinal beam (3) and a right longitudinal beam (4), a control arm support and spring arm supports are arranged on the auxiliary frame, and the spring arm supports comprise the left spring arm support (5) and the right spring arm support (6). The left spring arm support (5) and the right spring arm support are arranged on the inner side of the space defined by the auxiliary frame. The front cross beam further comprises a V-shaped cross beam (7), the two ends of the V-shaped cross beam (7) are connected with the left spring arm support (5) and the right spring arm support (6) respectively, the middle of the V-shaped cross beam (7) is connected with the rear cross beam (2), and a V opening formed by the V-shaped cross beam (7) faces the front cross beam (1). The size precision of the overall profile of the auxiliary frame is improved, arrangement is compact, and the requirement for arrangement space is lowered. And the durability and the rigidity are improved.
