The invention discloses an integrated hollow cast aluminum rear auxiliary frame which comprises a front cross beam, a rear cross beam, a middle cross beam, a left transmission shaft avoiding hole and a right transmission shaft avoiding hole, and the left lower end of the front cross beam is integrally connected with a left longitudinal beam; the rear cross beam is integrally connected to the lower right end of the left longitudinal beam, and the right end of the rear cross beam is integrally connected with the right longitudinal beam. The middle cross beam is integrally connected to the middle lower ends of the left longitudinal beam and the right longitudinal beam; the cross sections of the front cross beam, the left longitudinal beam, the rear cross beam, the right longitudinal beam and the middle cross beam form an H-shaped structure; the left transmission shaft avoiding hole is formed in the upper middle end of the left longitudinal beam; and the right transmission shaft avoiding hole is formed in the upper middle end of the right longitudinal beam. According to the integrated hollow cast aluminum rear auxiliary frame, the number of parts is reduced, the mold investment is reduced, the cost is reduced, and meanwhile, a mold side core-pulling structure is adopted, so that the demolding problem at the avoiding position of a transmission shaft is solved.

    本发明公开了一种一体空心铸铝后副车架,包括前横梁、后横梁、中间横梁、左传动轴避让孔和右传动轴避让孔,前横梁的左下端一体化连接有左纵梁;所述后横梁一体化连接在左纵梁的右下端,且后横梁的右端一体化连接有右纵梁;所述中间横梁一体化连接在左纵梁与右纵梁的中下端,前横梁、左纵梁、后横梁、右纵梁以及中间横梁的横截面构成“H”字形结构;所述左传动轴避让孔开设在左纵梁的上中端内部;所述右传动轴避让孔开设在右纵梁的上中端内部。该一体空心铸铝后副车架,便于减少零件数量,减少了模具投入,降低了成本,同时采用模具侧抽芯结构,解决了传动轴避让处脱模问题。
