The invention provides an auxiliary frame assembly and a vehicle. The auxiliary frame assembly comprises a first longitudinal beam, a second longitudinal beam, a front cross beam and a rear cross beam, wherein the front cross beam and the rear cross beam are arranged at an interval; the first longitudinal beam comprises a first longitudinal part and a first transverse part, and the first transverse part is connected between the front end of the first longitudinal part and the first end of the front cross beam; one end of the first longitudinal part away from the first transverse part is connected with the first end of the rear crossbeam; the second longitudinal beam comprises a second longitudinal part and a second transverse part; the second transverse part is connected between the front end of the second longitudinal part and the second end of the front cross beam; one end of the second longitudinal part away from the second transverse part is connected with the second end of the rear crossbeam. The section force of the auxiliary frame assembly in small offset collision is greatly improved, invasion to a passenger compartment is reduced, meanwhile, the economical efficiency and collision performance requirements of the whole vehicle are considered, and stable and effective crumple of the first longitudinal beam and the second longitudinal beam is guaranteed.

    本发明提供一种副车架总成及车辆,所述副车架总成包括第一纵梁、第二纵梁、前横梁以及与前横梁间隔设置的后横梁;第一纵梁包括第一纵向部以及第一横向部,第一横向部连接在所述第一纵向部的前端以及前横梁的第一端之间;第一纵向部远离第一横向部的一端连接后横梁的第一端;第二纵梁包括第二纵向部以及第二横向部,第二横向部连接在第二纵向部的前端以及前横梁的第二端之间;第二纵向部远离第二横向部的一端连接后横梁的第二端。本发明大大提升了副车架总成在小偏置碰中的截面力,减少了对乘员舱的侵入,同时兼顾了整车的经济性以及碰撞性能要求,也保证了第一纵梁和第二纵梁的溃缩稳定有效。
