The invention provides a rear auxiliary frame and a vehicle. The rear auxiliary frame comprises a front cross beam and a longitudinal beam, wherein the front end of the longitudinal beam is connected to the front cross beam; the top of the longitudinal beam is provided with a speed reducer installation sleeve used for installing a speed reducer, and the speed reducer installation sleeve is arranged close to the front cross beam. According to the rear auxiliary frame, the speed reducer installation sleeve used for installing the speed reducer is arranged at the position close to the connecting position of the front cross beam and the longitudinal beam, and the characteristic that the structural rigidity of the T-shaped intersection part is high can be fully utilized; the speed reducer mounting sleeve is arranged above the longitudinal beam, and is connected in a bearing manner instead of a hoisting manner, so that the connection burden between the speed reducer mounting sleeve and the longitudinal beam is reduced; and the structural stability of the reducer mounting part is improved.
本发明提供了一种后副车架及车辆。本发明的后副车架包括前横梁、以及前端连接在前横梁上的纵梁;其中,纵梁的顶部设有用于安装减速器的减速器安装套筒,而且减速器安装套筒靠近前横梁设置。本发明的后副车架,将用于安装减速器的减速器安装套筒设置在靠近前横梁和纵梁连接处的位置,可充分利用“T”形相交部位结构刚度强的特点;将减速器安装套筒设于纵梁上方,以承托而非吊装的形式连接减速器安装套筒,也利于减轻减速器安装套筒和纵梁之间的连接负担;有利于改善减速器安装部位的结构稳定性。
