The invention discloses a front auxiliary frame assembly of a non-bearing type vehicle, and relates to the technical field of vehicles. An auxiliary frame is formed by integrally arranging a bottom structure and two sets of side wall structures; the auxiliary frame is of a symmetrical structure in the XZ plane direction and the YZ plane direction. A plurality of groups of vertical ribs arranged in a matrix mode are arranged on the two groups of side wall structures, a plurality of side wall mounting holes with bosses are formed in the vertical ribs, and the two groups of side wall structures are attached to the inner side of the frame longitudinal beam and are fixed with the frame longitudinal beam by bolts through the side wall mounting holes; during assembly, the auxiliary frame is selected as the positioning reference of the front-end chassis, the frame longitudinal beam is provided with the mounting holes, and the arrangement mode of the mounting holes is consistent with that of the side wall mounting holes in the side wall structure of the auxiliary frame, so that the machining error of the frame longitudinal beam can be corrected, and the mounting precision is ensured; the overall structure of the auxiliary frame is arranged on the inner side of the frame longitudinal beam, so that the overall dimension of the auxiliary frame is reduced compared with an auxiliary frame in the prior art.

    本发明公开了一种非承载式车辆的前副车架总成,涉及车辆技术领域,所述副车架由底部结构与两组侧壁结构一体化布设;所述副车架于XZ平面方向以及YZ平面方向呈对称结构;两组所述侧壁结构上均设置有若干组呈矩阵式排列的竖筋,竖筋上开设有若干带凸台的侧壁安装孔,两组侧壁结构贴合于车架纵梁内侧,并用螺栓通过侧壁安装孔与车架纵梁进行固定;本发明在装配时,选择副车架作为前端底盘的定位基准,其中车架纵梁开有安装孔,其与副车架的侧壁结构上的侧壁安装孔排列方式一致,这样可以校正车架纵梁的加工误差,从而保证安装精度;副车架整体结构设置在车架纵梁内侧,使得副车架外廓尺寸相对于现有技术的副车架减小。
