The invention discloses a rear cross beam structure, a frame and a vehicle, the rear cross beam structure comprises a main body piece, a connecting piece and a mounting piece, through a first side wall which is concave up and down in a first direction and a second side wall which is convex in a second direction, the reliable bearing capacity of a rear cross beam to a load on a towing hook is improved, and due to the distance between a towing part and the towing hook, the towing hook is not damaged. The first structural section and the second structural section form the effect of further improving the overall torsion resistance of the first connecting section at different heights, the reliability of supporting a towed object is improved, the torsion force applied to the main body piece in the gravity direction and the composite dynamic inertia direction on the tow hook is reduced, torsion deformation on the main body piece is further avoided, and the tow hook is more stable in performance. The thickness of the whole rear cross beam mechanism can be reduced, the good light weight effect is achieved, the structural reliability of the whole rear cross beam structure is improved, the welding difficulty requirement and the quality risk are reduced, the whole vehicle control performance is improved, and the braking distance is shortened.
本发明公开了一种后横梁结构、车架及车辆,后横梁结构包括主体件、连接件以及安装件,通过第一方向上下凹的第一侧壁,通过第二方向上凸出的第二侧壁,提升后横梁对拖钩上荷载可靠的承托能力,由于拖挂部分与拖钩之间的距离,第一结构段与第二结构段以不同高度形成进一步增加第一连接段整体的抗扭转能力的效果,提高承托拖挂物时的可靠性,降低由于拖钩上沿重力方向复合动态惯性方向上施加到主体件上的扭转力,进一步避免主体件上出现扭转形变,后横梁机构整体可以降低厚度获得很好的轻量化效果,提高后横梁结构整体的结构可靠性,降低焊接难度要求与质量风险,提升整车操控性能,降低制动距离。
