The invention provides a rear auxiliary frame, a chassis structure and a vehicle. The rear auxiliary frame comprises rear auxiliary frame longitudinal beams arranged on the left side and the right side respectively, a rear auxiliary frame front cross beam and a rear auxiliary frame rear cross beam, the rear auxiliary frame front cross beam and the rear auxiliary frame rear cross beam are connected between the rear auxiliary frame longitudinal beams on the two sides, and a front cross beam is arranged between the front ends of the rear auxiliary frame longitudinal beams on the two sides; the front cross beam, the rear auxiliary frame front cross beam, the rear auxiliary frame rear cross beam and the rear auxiliary frame longitudinal beams on the two sides are connected to form a plurality of annular structures. Through the arrangement of the front cross beam, the structural strength of the rear auxiliary frame can be improved, the overall torsional rigidity of the rear portion of a vehicle can be improved, and good practicability is achieved.

    本发明提供了一种后副车架、底盘结构及车辆,本发明的后副车架包括分设在左右两侧的后副车架纵梁,以及连接在两侧所述后副车架纵梁之间的后副车架前横梁和后副车架后横梁,且两侧所述后副车架纵梁的前端之间设置有前部横梁;所述前部横梁、所述后副车架前横梁、所述后副车架后横梁,以及两侧所述后副车架纵梁连接形成多个环形结构。本发明通过前部横梁的设置,能够增加后副车架的结构强度,有利于车辆后部整体扭转刚度的提升,而有着很好的实用性。
