The invention belongs to the technical field of automobile parts, and particularly relates to a casting type rear auxiliary frame with an asymmetrical upper cross beam and an asymmetrical lower cross beam. The frame comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam which integrally combines into a trapezoid; the head ends of the left longitudinal beam and the right longitudinal beam are provided with butt-joint cylinders facing inwards along the transverse axis, a front cross beam is transversely connected between the butt-joint cylinders, the tail ends of the left longitudinal beam and the right longitudinal beam are provided with lower butt-joint cylinders facing inwards along the transverse axis, a rear cross beam is transversely connected between the lower butt-joint cylinders, the left longitudinal beam and the right longitudinal beam are of symmetrical structures, and sleeve lining cleats are arranged on the outer sides of the butt-joint cylinders, a folding corner is arranged below the sleeve lining cleat, an adapter set is arranged on the inner side of the corner intersection inside the middle frame connector, and a branch adapter is further arranged on the portion, below the stretching longitudinal beam body, of the adapter set. According to the rear auxiliary frame provided by the embodiment of the invention, the left longitudinal beam and the right longitudinal beam are of a symmetrical structure, therefore, the adapter, the right front support bracket, the branch adapter and the right lower swing arm bracket on the right front support bracket, the branch adapter and the right lower swing arm bracket can be ensured to be stably connected, and the structure mode is optimized.

    本发明属于汽车零部件技术领域,尤其涉及一种非对称上、下横梁的铸造式后副车架。包括前横梁、后横梁、左纵梁、右纵梁整体组合为梯形;所述左纵梁、右纵梁的头端朝内横轴线设置对接筒,对接筒之间横向连接设置前横梁,所述左纵梁、右纵梁的尾端端朝内横轴线设置下对接筒,下对接筒之间横向连接设置后横梁,所述左纵梁、右纵梁对称结构,对接筒的外侧设置套衬羊角,套衬羊角下方设置折口角,中架连接头内部角交内侧设置转接头组,转接头组在伸纵梁正体下方还设置分支转接头,根据发明实施例的后副车架,左纵梁、右纵梁是对称结构,所以他们上面的转接头、右前支撑支架、分支转接头和右下摆臂支架之间能保证的连接稳固,以及最优化的结构模态。
