The invention belongs to the technical field of vehicle engineering, and particularly relates to an oil tank and rear axle integrated rear frame system which comprises an oil tank, a rear frame and a rear axle. The rear frame comprises a crumple section and a first reinforcing section which are sequentially arranged from front to back, the rear axle is mounted on the lower side of the crumple section through a rear axle suspension, and the oil tank is fixedly mounted on the lower side of the first reinforcing section; the front end of the first reinforcing section is flush with the front end of the oil tank, the rear end of the crumple section extends out of the rear end of the rear axle, the front end of the crumple section at least extends to the front end of the rear axle, a first binding face is arranged in the center of the front end of the oil tank, and two second binding faces are further arranged at the front end of the oil tank. The two second binding surfaces are symmetrically arranged on the left side and the right side of the first binding surface; the collapsing section is used for collapsing and absorbing energy when the rear end of the first reinforcing section is impacted, the first binding face is used for being attached to the rear side face of a main cross beam of the rear axle after the collapsing section collapses, and the two second binding faces are used for being attached to the rear side faces of the two rear axle suspensions after the collapsing section collapses.

    本发明属于车辆工程技术领域,具体涉及一种集成油箱和后桥的后车架系统,包括油箱、后车架和后桥;后车架包括由前向后依次设置的溃缩段和第一加强段,后桥通过后桥悬置安装在溃缩段的下侧,油箱固定安装在第一加强段的下侧;第一加强段的前端与油箱的前端平齐,溃缩段的后端伸出后桥的后端之外,溃缩段的前端至少伸出至后桥的前端,油箱的前端的中央设置有第一贴合面,油箱的前端还设置有两个第二贴合面,两个第二贴合面对称设置在第一贴合面的左右两侧;溃缩段用于在第一加强段的后端受到撞击时溃缩吸能,第一贴合面用于在溃缩段发生溃缩后与后桥的主横梁的后侧面贴合,两个第二贴合面分别用于在溃缩段发生溃缩后与两个后桥悬置的后侧面贴合。
