The rear auxiliary frame assembly comprises an auxiliary frame, a front cross beam and a rear cross beam which are distributed in the longitudinal direction of the vehicle at intervals and connected between two frame longitudinal beams to jointly define an electric drive containing space, at least part of each frame longitudinal beam is of an arch structure, and the arch structures arch upwards; an avoiding space is formed below the arched structure, and a steering gear avoiding hole is formed in the rear cross beam and used for avoiding a steering gear; and the electric drive assembly is installed at the electric drive containing space, the electric drive assembly is in power connection with a drive shaft, and the drive shaft penetrates out of the electric drive containing space from the avoiding space. According to the rear auxiliary frame assembly, the overall integration degree of the rear auxiliary frame assembly can be improved, then the light weight of the whole vehicle can be improved, the endurance performance of the vehicle can be guaranteed, the use experience of a user can be improved, the structural strength and durability of the auxiliary frame can be improved, then the use safety of the rear auxiliary frame assembly can be guaranteed, and the application range is wider.

    本发明公开了一种后副车架总成和车辆,包括:副车架,前横梁和后横梁沿车辆纵向间隔分布且分别连接于两个车架纵梁之间以共同限定出电驱容纳空间,每个车架纵梁的至少部分构造为拱形结构,拱形结构朝上拱起,以在拱形结构的下方形成避让空间,后横梁形成有转向器避让孔,转向器避让孔用于避让转向器;电驱总成,电驱总成安装于电驱容纳空间处,且电驱总成动力连接有驱动轴,驱动轴从避让空间处穿设至电驱容纳空间外。本发明实施例的后副车架总成,可提高后副车架总成整体的集成度,进而可提高整车轻量化,保证车辆续航性能,提高用户使用体验,且可提高副车架的结构强度以及耐久性,进而可保证后副车架总成的使用安全性,适用范围更广。
