The invention discloses a rear auxiliary frame mounting seat and a vehicle, the rear auxiliary frame mounting seat is characterized in that the upper part of a first reinforcing piece is fixedly connected with a longitudinal beam and a cross beam respectively, the first reinforcing piece comprises a main reinforcing plate, the main reinforcing plate is positioned on the lower sides of the cross beam and the longitudinal beam, and the part, opposite to the longitudinal beam, of the main reinforcing plate is provided with a mounting position for mounting a rear auxiliary frame; a plurality of arch structures which are sequentially connected are formed on the front side of the first reinforcing piece, the height-width ratios of every two adjacent arch structures are different, and a part of the second reinforcing piece is located between the main reinforcing plate and the longitudinal beam, stacked with the main reinforcing plate and connected with the main reinforcing plate. And the other part of the second reinforcing piece extends between the main reinforcing plate and the longitudinal beam and is connected with the longitudinal beam. According to the rear auxiliary frame mounting seat, the mounting position used for mounting the rear auxiliary frame is arranged on the first reinforcing part, the multiple sequentially-connected arch structures are formed on the front side of the first reinforcing part, and the second reinforcing part is arranged, so that the dynamic stiffness of the mounting position can be improved, and vibration transmitted from the road surface is reduced.

    本发明公开了一种后副车架安装座和车辆,所述后副车架安装座包括:第一加强件的上部分别固定连接纵梁和横梁,第一加强件包括主加强板,主加强板位于横梁和纵梁的下侧,主加强板与纵梁相对的部分具有用于安装后副车架的安装位,第一加强件的前侧形成有依次连接的多个拱形结构,相邻两个拱形结构的高宽比不同,第二加强件的部分位于主加强板和纵梁之间且与主加强板层叠设置,并与主加强板连接,第二加强件的另一部分伸出主加强板和纵梁之间并与纵梁连接。根据本发明的后副车架安装座,通过在第一加强件上设置用于安装后副车架的安装位和在前侧形成多个依次连接的拱形结构,并设置第二加强件,可以提高安装位的动刚度,降低路面传递过来的振动。
