The rear auxiliary frame comprises a first longitudinal beam, a second longitudinal beam, a first cross beam, a second cross beam and a support assembly. The support assembly comprises a first installation support and a second installation support, and the first installation support and the second installation support are symmetrically arranged on the first longitudinal beam and the second longitudinal beam respectively towards the sides deviating from the installation structure. The rear auxiliary frame further comprises a first longitudinal reinforcing piece, a second longitudinal reinforcing piece and a transverse reinforcing piece, the two ends of the transverse reinforcing piece are transversely connected with the first installation support and the second installation support respectively, and the two ends of the first longitudinal reinforcing piece are longitudinally connected with the first installation support and the first cross beam respectively. Two ends of the second longitudinal reinforcer are longitudinally connected with the second mounting bracket and the second cross beam respectively. According to the rear auxiliary frame, the dynamic stiffness of the mounting supports is improved, the first mounting supports and the second mounting supports are arranged towards the sides deviating from the mounting structure, so that the height of the transverse reinforcing pieces can be set to be relatively low, and the mounting space of a vehicle motor is enlarged.

    本申请涉及一种后副车架,包括第一纵梁、第二纵梁、第一横梁、第二横梁及支架组件。其中,支架组件包括第一安装支架及第二安装支架,第一安装支架及第二安装支架朝背离安装结构的一侧分别对称设置于第一纵梁及第二纵梁。后副车架还包括第一纵向加强件、第二纵向加强件及横向加强件,横向加强件的两端分别横向连接第一安装支架及第二安装支架,第一纵向加强件的两端分别纵向连接第一安装支架及第一横梁,第二纵向加强件的两端分别纵向连接第二安装支架及第二横梁。上述后副车架,不仅提高了安装支架的动刚度,还通过第一安装支架及第二安装支架朝背离安装结构的一侧的设置,使得横向加强件的高度能够设置得相对较低,提高了车辆电机安装空间。
