The invention relates to the technical field of auxiliary frames, and discloses an auxiliary frame assembly and a vehicle, the auxiliary frame assembly comprises a cross beam body, a suspension support and two longitudinal beam assemblies, in the first direction, the cross beam body is fixedly connected between the two longitudinal beam assemblies, a first cavity is formed in the suspension support, the first cavity is provided with a first opening, and in the second direction, the cross beam body is fixedly connected between the two longitudinal beam assemblies; the projection of the first opening is located outside the cross beam body, the cross beam body comprises a cross beam upper plate and a cross beam lower plate, the cross beam upper plate is fixedly connected with the cross beam lower plate in a buckled mode, the suspension support is fixedly installed on the cross beam body, and in the second direction, part of the suspension support protrudes out of the cross beam lower plate; the upper beam plate, the lower beam plate and the suspension support jointly form a second cavity separated from the first cavity, and the first direction is perpendicular to the second direction. Therefore, a multi-cavity structure of the cross beam body and the suspension support is achieved, and the overall dynamic stiffness of the auxiliary frame assembly can be improved.

    本申请涉及副车架技术领域,公开了一种副车架总成及车辆,副车架总成包括:横梁本体、悬置支架和两个纵梁组件,沿第一方向,横梁本体固定连接在两个纵梁组件之间,悬置支架内形成有第一空腔,第一空腔具有第一开口,沿第二方向,第一开口的投影位于横梁本体的外部,横梁本体包括横梁上板和横梁下板,横梁上板与横梁下板扣合固定连接,悬置支架固定安装于横梁本体,且沿第二方向,悬置支架的部分凸出于横梁下板,横梁上板、横梁下板、悬置支架共同形成有与第一空腔分隔开的第二空腔,其中,第一方向与第二方向相互垂直。由此,实现了横梁本体与悬置支架的多空腔结构,有利于提高副车架总成的整体动刚度。
