The reinforced rear auxiliary frame comprises a left longitudinal beam, a left middle longitudinal beam, a right middle longitudinal beam, a right longitudinal beam, a front cross beam and a rear cross beam, the front end of the left longitudinal beam is connected with the front cross beam, the right end of the rear cross beam is connected with the right longitudinal beam, the rear end of the left longitudinal beam is connected with the rear cross beam, and the front end of the right longitudinal beam is connected with the front cross beam. A left middle longitudinal beam is arranged on the right side of the left longitudinal beam, the left middle longitudinal beam and the right middle longitudinal beam are of a horn mouth structure, the lap joint structure of the left longitudinal beam, the right longitudinal beam and the front cross beam adopts the semi-lap joint characteristic, and a front upper swing arm body is welded to the joint of the front cross beam and the left longitudinal beam. According to the reinforced rear auxiliary frame, the thickness of the cross beam and the longitudinal beam during material selection is obviously reduced, the weight reduction effect is achieved, the auxiliary frame is firm in structure, swing arm installation points are arranged on accessories of the longitudinal beam and the cross beam, support can be well provided for the swing arm installation points, the effect of improving the rigidity of the swing arm points is achieved, and use is flexible.

    本发明公开了一种加强型后副车架,包括左边纵梁、左中纵梁、右中纵梁、右边纵梁、前横梁和后横梁,所述左边纵梁的前端连接有前横梁,且后横梁的右端连接有右边纵梁,所述左边纵梁的后端连接有后横梁,所述右边纵梁的前端连接有前横梁,所述左边纵梁的右侧设置有左中纵梁,所述左中纵梁与右中纵梁为喇叭口结构,所述左边纵梁与右边纵梁与前横梁搭接结构采取了半搭接特征,所述前横梁与左边纵梁的连接处焊接有前上摆臂本体。该加强型后副车架,明显降低横梁和纵梁材料选取时的厚度,起到减重的效果,并且因为副车架结构牢固,且摆臂安装点均在纵梁和横梁附件,可以很好的为摆臂安装点提供支撑,起到提高摆臂点刚度的作用,使用灵活。
