The auxiliary frame assembly comprises longitudinal beams, a front cross beam, a rear cross beam and a plurality of control arm supports, the front cross beam is connected between the two opposite longitudinal beams and connected to the front ends of the longitudinal beams, the rear cross beam is connected between the two opposite longitudinal beams and connected to the rear portions of the longitudinal beams, and the control arm supports are connected to the longitudinal beams and connected to the front ends of the longitudinal beams. The joint of the longitudinal beam and the front cross beam is located on the front side of the joint of the longitudinal beam and the control arm supports, and the joint of the longitudinal beam and the rear cross beam is located on the rear side of the joint of the longitudinal beam and the control arm supports. According to the auxiliary frame assembly, the front cross beam and the rear cross beam are arranged between the longitudinal beams, the longitudinal beams, the cross beams and the control arm supports are connected with one another, and therefore the overall structural strength of the auxiliary frame assembly can be improved, the avoiding space is formed below the control arm supports, and therefore the driving structure can be conveniently installed in the auxiliary frame assembly; and the spatial arrangement requirement of the rear axle electric driving system can be met, so that the performance of the vehicle can be improved.

    本发明公开了一种副车架总成和车辆,副车架总成包括:纵梁、前横梁、后横梁和多个控制臂支架,前横梁连接于相对的两个纵梁之间且连接于纵梁的前端,后横梁连接于相对的两个纵梁之间且连接于纵梁的后部,多个控制臂支架连接于纵梁,纵梁的与前横梁的连接处位于纵梁的与多个控制臂支架的连接处的前侧,纵梁的与后横梁的连接处位于纵梁的与多个控制臂支架的连接处的后侧。通过在纵梁之间设置前横梁和后横梁,纵梁、横梁和多个控制臂支架相互连接,从而可以提升副车架总成的整体结构强度,而且多个控制臂支架的下方形成避让空间,从而便于驱动结构安装在副车架总成中,还可以满足后桥电驱动系统的空间布置需求,进而可以提升车辆的性能。
