The invention relates to a vehicle cross beam assembly. Comprising a first beam plate, a second beam plate and a reinforcing beam, the second beam plate is arranged on the first beam plate, the second beam plate and the first beam plate are assembled to form a first cavity, the reinforcing beam is arranged between the first beam plate and the second beam plate, and a second cavity is formed in the reinforcing beam; according to the automobile cross beam assembly, the rigidity of the automobile cross beam assembly is improved by increasing the number of the cavities, that is, the second cavity is additionally formed in the first cavity, so that compared with a traditional automobile cross beam structure, the sectional area of the automobile cross beam assembly structure is greatly increased, and the bending rigidity and torsional rigidity of the automobile cross beam assembly to a whole automobile are improved; meanwhile, the rigidity and the strength of the vehicle cross beam assembly are enhanced; in addition, due to the fact that the closed cavity has excellent structural stability, the connecting strength and rigidity between the reinforcing beam and the second beam plate can be effectively guaranteed.

    本发明涉及一种车横梁总成;包括第一梁板、第二梁板和加强梁,第二梁板设置在第一梁板上,并与第一梁板装配形成第一空腔,加强梁设置在第一梁板和第二梁板之间,加强梁内具有第二空腔;本申请的车横梁总成,通过增加腔体数量的方式提高车横梁总成的刚度,即通过在第一空腔内增加第二空腔,使该车横梁总成结构相比传统汽车横梁结构,其截面积有较大增加,提高了车横梁总成对整车的弯曲刚度和扭转刚度,同时增强了车横梁总成的刚度和强度;此外,由于封闭腔体具有优异的结构稳定性,因此可有效保证加强梁与第二梁板间的连接强度及刚度。
