The invention provides a frame cross beam assembly which comprises a cross beam body, the cross beam body is a groove-shaped beam, and the cross beam body comprises an upper wing plate, a lower wing plate and a web plate located between the upper wing plate and the lower wing plate. Main connecting plates are fixedly connected to the outer sides of the four ends of the upper wing plate and the outer sides of the four ends of the lower wing plate, and the two main connecting plates located at the same end of the upper wing plate and the lower wing plate are arranged in a mirror symmetry mode. Auxiliary connecting plates are fixedly connected to the outer sides of the two end parts of the web plate; the main connecting plate and the auxiliary connecting plate are provided with a plurality offirst mounting holes and second mounting holes respectively, wherein the first mounting holes and the second mounting holes are connected with longitudinal beams of the frame. The stress transmissioneffect of the frame cross member can be improved, the stress transmission is balanced, the stress concentration is reduced, the overall rigidity is improved, and the cracking risk of the whole frameis reduced.

    一种车架横梁总成,包括横梁本体,横梁本体为槽型梁,横梁本体包括上翼板、下翼板和位于上翼板与下翼板之间的腹板;上翼板和下翼板的四个端部外侧均固定连接有主连接板,位于上翼板和下翼板同一端的两主连接板镜像对称设置;腹板的两端部外侧均固定连接有副连接板;主连接板和副连接板上分别设置有用于与车架的纵梁连接的若干第一安装孔和第二安装孔。本发明能够改善车架横梁的应力传递效果,平衡应力传递,降低应力集中,提高整体刚度,减小整个车架的开裂风险。
