The invention relates to a rear auxiliary frame and a vehicle, the rear auxiliary frame comprises a front cross beam used for installing a rear suspension system, and the front cross beam comprises a front cross beam upper plate; the two front cross beam side plates are connected to the front side and the rear side of the front cross beam upper plate correspondingly and used for installing a first control arm, and the bottoms of the two front cross beam side plates are in lap joint so that the front cross beam upper plate and the two front cross beam side plates can define a circumferentially-closed frame-shaped structure; the two front cross beam lower plates are arranged below the left end and the right end of the front cross beam upper plate respectively, the front cross beam lower plates are in lap joint with the front cross beam upper plate and the two front cross beam side plates respectively, the front cross beam lower plates and the two front cross beam side plates form receding holes for a first control arm to move, and the front cross beam lower plates and the front cross beam upper plate define a frame-shaped structure which is closed in the circumferential direction. Therefore, by reasonably splitting the front cross beam, a closed section structure within the full width range of the front cross beam is realized to the greatest extent while avoiding the movement of the first control arm, and the rigidity and the bearing capacity of the rear auxiliary frame are greatly improved.
本公开涉及一种后副车架和车辆,后副车架包括用于安装后悬架系统的前横梁,前横梁包括:前横梁上板;两块前横梁侧板,分别连接在前横梁上板的前后两侧,用于安装第一控制臂,两块前横梁侧板的底部相互搭接,以使得前横梁上板与两块前横梁侧板围成周向封闭的框形结构;以及两块前横梁下板,分别设置在前横梁上板的左右两端的下方,前横梁下板分别与前横梁上板和两块前横梁侧板搭接,其中,前横梁下板与两块前横梁侧板形成用于供第一控制臂运动的避让孔,并与前横梁上板围成周向封闭的框形结构。这样,通过合理拆分前横梁,在避让第一控制臂运动的同时,最大限度地实现前横梁全宽范围内的封闭式断面结构,大幅提升后副车架的刚度和承载能力。
