The invention provides a rear auxiliary frame assembly and a vehicle. The rear auxiliary frame assembly comprises an auxiliary frame and an electric drive assembly. The auxiliary frame comprises a front cross beam, a rear cross beam and two frame longitudinal beams, the front cross beam and the rear cross beam are distributed in the longitudinal direction of a vehicle at intervals and connected between the two frame longitudinal beams to jointly define an electric drive containing space, and at least part of each frame longitudinal beam is of an arch structure. The arch structure arches upwards, and an avoiding space is formed below the arch structure; the electric drive assembly is installed in 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 arched structure of the frame longitudinal beam can improve the strength, the electric drive assembly is installed in the electric drive containing space, the drive shaft extends to the avoiding space formed by the arched structure, the integration degree is high, and the space is saved.
本发明提出了一种后副车架总成及车辆,所述后副车架总成包括:副车架和电驱总成;所述副车架包括前横梁、后横梁和两个车架纵梁,所述前横梁和所述后横梁沿车辆纵向间隔分布且分别连接于两个所述车架纵梁之间以共同限定出电驱容纳空间,每个所述车架纵梁的至少部分构造为拱形结构,所述拱形结构朝上拱起且以在所述拱形结构的下方形成避让空间;所述电驱总成安装于所述电驱容纳空间处,且所述电驱总成动力连接有驱动轴,所述驱动轴从所述避让空间处穿设至所述电驱容纳空间外。本发明实施例的后副车架总成,车架纵梁的拱形结构可以提高强度,并且将电驱总成安装在电驱容纳空间处,驱动轴伸至拱形结构形成的避让空间处,集成度高且节省空间。
