According to the rear auxiliary frame assembly and the automobile, the rear auxiliary frame assembly is integrally made of the aluminum metal material which is light in weight and good in structural strength, the interior of the rear auxiliary frame assembly is integrally cast in a hollow mode, and the tightness degree of structures on the rear auxiliary frame assembly and uniform distribution of bearing capacity of all parts are guaranteed; the rear auxiliary frame assembly comprises a rear beam frame, side beam frames and a front beam frame, the side beam frames extend outwards in the vertical direction of the two sides of the rear beam frame, the front beam frame is arranged on the sides, away from the rear beam frame, of the side beam frames, the rear beam frame, the side beam frames and the front beam frame are integrally connected and jointly form the rear auxiliary frame assembly, and the bottoms of the side beam frames extend outwards to form reinforcing frames. The two ends of the reinforcing frame are further connected with the rear beam frame and the front beam frame respectively, the bearing strength of the side beam frames can be improved through the reinforcing frame, meanwhile, the two ends of the reinforcing frame are further connected with the rear beam frame and the front beam frame respectively, and the bearing strength of the rear beam frame and the front beam frame and the structural stability are further improved.

    本发明提供一种后副车架总成及汽车,后副车架总成整体采用重量较轻且结构强度较好的铝金属材料制成,且后副车架总成内部是采用一体空心铸造,确保后副车架总成上结构之间的紧密程度以及各部位承载力的均匀分布,后副车架总成包括后梁架、沿后梁架两侧垂直方向向外延伸出的侧梁架以及设置在两侧梁架远离后梁架一侧的前梁架,其中,后梁架、侧梁架以及前梁架为一体式连接且共同组成后副车架总成,侧梁架底部向外延伸出加强架,加强架两端还分别连接后梁架和前梁架,其中通过加强架能够提高侧梁架的承载强度,同时两端还分别与后梁架和前梁架连接,达到进一步提高后梁架与前梁架的承载强度以及结构的稳定性。
