Comprising a front tubular beam, a rear tubular beam, a front suspension mounting bracket and a longitudinal beam, the two longitudinal beams are arranged in parallel, and the rear tubular beam and the front tubular beam are arranged at intervals and fixedly connected between the two longitudinal beams in a lap joint mode to form a frame body. The middle part of the front tubular beam is an arched straight section, and the two front suspension mounting brackets are symmetrically arranged on the arched straight section and are opposite to the arched direction; the front and back sides of the frame body can be used. According to the rear auxiliary frame with the structure, the change of the spatial position height of the motor of the SUV type and the Sedan type can be considered, meanwhile, although the rear auxiliary frame assembly is different in part number, all sub-parts of the rear auxiliary frame assembly can be universal, other sub-parts do not need to be additionally arranged, and the mold development cost is saved; and when the front tubular beam and the front mounting point sleeve are welded (because the matching difference between the SUV model and the Sedan model is 180 degrees), the welding can be carried out on the same pair of welding fixtures, and a pair of welding fixtures is saved.

    包括前管梁、后管梁、前悬置安装支架和纵梁;两个纵梁平行布置,后管梁与前管梁间隔布置,并搭接固连于两个纵梁之间形成车架主体;前管梁的中部为拱起平直段,两个前悬置安装支架对称布置在拱起平直段上,且与拱起方向相反;车架主体能够正反面使用。此结构后副车架可以兼顾SUV车型和Sedan车型的电机空间位置高度的变化,同时又使得后副车架总成虽然是不同零件号,但是其子零件全部能够通用,不需要新增加其他子零件,节省了模具开发费用;在焊接前管梁与前安装点套管时(由于SUV车型与Sedan车型这两个件配合相差180°),可以在同一副焊接夹具上进行,又节省了一副焊接夹具。
