The invention relates to an auxiliary frame structure and a vehicle, the auxiliary frame structure comprises an annular frame, the annular frame comprises a front cross beam and a rear cross beam which are arranged at intervals in the front-back direction, and a left longitudinal beam and a right longitudinal beam which are arranged at intervals in the left-right direction, the left longitudinal beam is connected to the left end of the front cross beam and the left end of the rear cross beam, and the right longitudinal beam is connected to the right end of the rear cross beam; the right longitudinal beam is connected to the right ends of the front cross beam and the rear cross beam; the upper cross beam and the lower cross beam are arranged at intervals in the vertical direction, the upper cross beam is fixedly connected to the upper side wall of the left longitudinal beam and the upper side wall of the right longitudinal beam, and the lower cross beam is fixedly connected to the lower side wall of the left longitudinal beam and the lower side wall of the right longitudinal beam. Thus, when the auxiliary frame structure is installed on the vehicle, a new force transmission path can be increased through the structure of the upper cross beam and the lower cross beam, meanwhile, the load bearing capacity of the auxiliary frame structure in the front-back direction, the left-right direction and the torsion direction is improved, and therefore the strength of the auxiliary frame structure is integrally improved.
本公开涉及一种副车架结构及车辆,该副车架结构,包括:环形框架,包括在前后方向间隔设置的前横梁和后横梁,在左右方向间隔设置的左纵梁和右纵梁,所述左纵梁连接于所述前横梁和所述后横梁的左端,所述右纵梁连接于所述前横梁和所述后横梁的右端;以及上横梁和下横梁,在上下方向间隔设置,所述上横梁固定连接于所述左纵梁的上侧壁和所述右纵梁的上侧壁,所述下横梁固定连接于所述左纵梁的下侧壁和所述右纵梁的下侧壁。如此,在副车架结构安装在车辆上时,能够通过上横梁和下横梁的结构,增加新的传力路径、同时增加副车架结构在前后方向、左右方向以及扭转的承载载荷的能力,从而整体提高了副车架结构的强度。
