The invention relates to the technical field of manufacturing and production of automobiles and auxiliary frames, in particular to a new energy large-bend side beam rear auxiliary frame. The pipe body longitudinal camber beam of the pipe type structure is easy to manufacture and does not need to be welded, and the number of parts can be reduced and the cost can be reduced by combining the metal plate front beam which is spliced vertically front and back. Comprising a front cross beam front plate and a front cross beam rear plate, the front cross beam front plate and the front cross beam rear plate are spliced and welded into a whole in a front-back mode, the interior of the front cross beam front plate is hollow, the two sides of the front cross beam rear plate are open, and the front cross beam front plate and the front cross beam rear plate are arranged beside the rear cross beam and the left longitudinal beam in a left-right sleeving mode; the rear cross beam comprises a rear cross beam upper plate and a rear cross beam lower plate which are vertically spliced and welded into a whole, the rear cross beam is hollow, two sides of the rear cross beam are open, and the rear cross beam and the left longitudinal beam side are sleeved with the rear cross beam left and right; a swallow-shaped bottom plate is further arranged at the bottom of the rear cross beam, an upper side turning piece is arranged in the center of the swallow-shaped bottom plate, the upper side turning piece is arranged on the outer wall of a lower plate of the rear cross beam in a sleeved and attached mode and is welded and fixed, and the head side and the tail side of the swallow-shaped bottom plate are bent forwards and connected to the bottom of the rear cross beam or the bottom of the left longitudinal beam in a lap joint mode.

    本发明涉及汽车、副车架制造和生产技术领域,具体为一种新能源大弯侧梁后副车架。管型结构的管体纵弯梁,不仅制作简单而且不用焊接,结合竖向前后拼合的钣金前梁两能对比的减少零件降低成本。包括由前横梁、后横梁、左纵梁、右纵梁组成井字或框体车架结构,其中:所述前横梁包括前横梁前板和前横梁后板,两者前后拼接焊合为一体,内部中空,两侧开口,并左右套入后横梁和左纵梁侧旁;所述后横梁,包括后横梁上板和后横梁下板两者上下拼合并焊接为一体,内部中空,两侧开口,并左右套入后横梁和左纵梁侧旁;且后横梁底部还设置燕形底板,燕形底板的中央设置上侧翻片,上侧翻片套贴设置在后横梁下板外壁上并焊接固定,且燕形底板的头尾两侧向前弯折,并搭接在后横梁或左纵梁的底部。
