The invention discloses a novel aluminum alloy auxiliary frame which comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, and the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam are all of a hollow tubular structure formed by extrusion forming of aluminum alloy sections. The auxiliary frame further comprises a left front mounting bracket, a right front mounting bracket, a left rear mounting bracket and a right rear mounting bracket; the left front mounting bracket, the right front mounting bracket, the left rear mounting bracket and the right rear mounting bracket are all formed by casting aluminum alloy. According to the novel aluminum alloy auxiliary frame, through the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam which are formed through extrusion, the weight is light, the yield is high, the cost is low, and welding is easy to control; the left front mounting bracket, the right front mounting bracket, the left rear mounting bracket and the right rear mounting bracket need to be connected with other parts of a vehicle body or a chassis, structural changes are complex, and the mechanical performance of casting parts formed through casting is improved.
本发明公开了一种新型铝合金副车架,包括前横梁、后横梁、左纵梁和右纵梁,所述前横梁、后横梁、左纵梁和右纵梁均采用铝合金型材挤压成形,形成的中空管状结构;所述副车架还包括左前安装支架、右前安装支架、左后安装支架和右后安装支架;所述左前安装支架、右前安装支架、左后安装支架和右后安装支架均采用铝合金铸造而成;本发明的一种新型铝合金副车架,通过挤压成形的前横梁、后横梁、左纵梁和右纵梁,质量轻、成品率高,成本低,焊接易于控制;而本发明的左前安装支架、右前安装支架、左后安装支架和右后安装支架需要与车身或底盘其他部位进行连接,结构变化较为复杂,通过铸造成形的铸造件,有利于提高其机械性能。
