The invention relates to the technical field of auxiliary frames, and discloses an auxiliary frame assembly and a vehicle, the auxiliary frame assembly comprises two cross beam bodies and at least two shock absorber mounting supports, the at least two cross beam bodies are arranged in a spaced mode in the first direction, each cross beam body is used for being connected with a frame, and the shock absorber mounting supports are arranged in the second direction. The two shock absorber installation supports are arranged in a spaced mode, each shock absorber installation support is fixedly connected between the two cross beam bodies, each shock absorber installation support is provided with an installation protrusion used for installing a shock absorber, and the first direction is perpendicular to the second direction. Therefore, integration of shock absorber installation functions is achieved on the auxiliary frame assembly, the auxiliary frame assembly is more compact, meanwhile, the anti-deformation capacity of the shock absorber installation support can be improved by arranging the installation protrusions on the shock absorber installation support, the strength and rigidity of the auxiliary frame assembly can be improved, and the service life of the auxiliary frame assembly is prolonged. Therefore, the vibration isolation performance and the NVH performance of the auxiliary frame assembly are 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:两个横梁本体和至少两个减震器安装支架,沿第一方向,至少两个横梁本体间隔设置,且每个横梁本体均用于与车架连接,沿第二方向,两个减震器安装支架间隔设置,且每个减震器安装支架均固定连接在两个横梁本体之间,其中,每个减震器安装支架均具有用于安装减震器的安装凸起,第一方向与第二方向垂直。由此,不仅在副车架总成实现了减震器安装功能的集成,而且使得副车架总成更加紧凑,同时,通过在减震器安装支架设置安装凸起可以提高减震器安装支架自身的抗变形能力,从而有利于提高副车架总成的强度和刚度,进而提高副车架总成的隔振性能和NVH性能。
