The invention discloses a multi-connecting-rod cast aluminum rear auxiliary frame which comprises a rear beam, a front beam and a longitudinal beam which are of an integrated cast structure. The spring arm mounting point is arranged on one side of the middle of the longitudinal beam, and an inclined strut used for assisting the spring arm mounting point in use is fixed between the rear beam and the longitudinal beam; the upper cross arm support is integrally arranged on the lower portion of the outer side of the longitudinal beam, the inclined struts are symmetrically arranged on the two sides of the rear beam, the inclined struts and the rear beam are combined to form an n-shaped structure, and a frame-shaped structure is formed among the rear beam, the longitudinal beam and the inclined struts. According to the multi-connecting-rod cast aluminum rear auxiliary frame, an n-shaped structure and a frame-shaped structure are applied, the contradiction between the requirement for high rigidity of a spring arm mounting point of a suspension system and the situation that no space is arranged in the middle of the auxiliary frame is solved, and meanwhile the problem that the rigidity of an upper cross arm support is reduced due to avoidance of a steering engine is solved through C-shaped reinforcing ribs.
本发明公开了一种多连杆铸铝后副车架,包括后梁、前梁和纵梁,所述后梁、前梁和纵梁为一体铸造结构;还包括:弹簧臂安装点,所述弹簧臂安装点设置在纵梁的中部一侧,后梁与纵梁之间固定有用于辅助弹簧臂安装点使用的斜撑;上横臂支架,所述上横臂支架一体化设置在纵梁的外侧下部,所述斜撑在后梁的两侧呈对称设置,且斜撑与后梁之间组合构成п形结构,所述后梁、纵梁和斜撑之间形成框形结构。该多连杆铸铝后副车架,方案应用п形和框形结构,解决了悬架系统弹簧臂安装点的高刚度需求与副车架中部无空间布置横梁结构之间的矛盾,同时利用C形加强筋改善了上横臂支架由于转向机避让带来的刚度降低问题。
