The invention relates to an automobile front assembly which comprises a front longitudinal beam, threshold boundary beams, a front wall plate and a front wall plate lower cross beam, the front wall plate lower cross beam is fixed on the front wall plate, the front wall plate lower cross beam is fixedly connected with the front longitudinal beam, and the front wall plate lower cross beam is fixedly connected with the corresponding threshold boundary beams. According to the structure, the problem of a force transmission channel is solved, the front floor upper reinforcing longitudinal beams are additionally arranged on the two sides of the front floor on the rear portion of the front longitudinal beams, the effect of transmitting direct impact force is achieved, meanwhile, the front floor middle section is additionally arranged on the front floor structure, and the effect of transmitting the direct impact force from the middle position of the front floor is achieved; in this way, five force transmission paths are formed, the front collision force is effectively dispersed, the requirements of various power assemblies are met, and meanwhile the strict requirements of CNCAP-five stars are met.

    本发明涉及一种汽车前部总成,包括前纵梁、门槛边梁以及前围板,还包括前围板下横梁,所述前围板下横梁固定在所述前围板上,所述前围板下横梁与前纵梁固定连接,所述前围板下横梁与对应的所述门槛边梁固定连接。本发明的结构解决传力通道问题,在前纵梁后部的前地板两侧上增加了前地板上加强纵梁,起到传递正碰力的作用,同时在前地板结构上增加前地板中段,起到从前地板中部位置传动正碰力的作用,这样就形成了5条传力路径有效分散了前碰的力,不仅满足了多种动力总成的需求,同时满足CNCAP‑五星的严苛要求。
