The invention discloses a longitudinal beam assembly for a vehicle, a vehicle body assembly and the vehicle. The longitudinal beam assembly comprises a longitudinal beam body, a first reinforcing piece, a second reinforcing piece and a connecting piece, wherein a bottom plate is formed on the longitudinal beam body; the first reinforcing piece and the second reinforcing piece are arranged on the two sides of the bottom plate, and at least one of the first reinforcing piece and the second reinforcing piece and the bottom plate are arranged in a spaced mode to form a reinforcing cavity. The connecting piece sequentially penetrates through the first reinforcing piece, the bottom plate and the second reinforcing piece, and an auxiliary frame mounting point is arranged at the end of the connecting piece. According to the longitudinal beam assembly, the auxiliary frame is connected with the longitudinal beam body through the connecting piece, the first reinforcing plate and the second reinforcing plate are arranged at the connecting point position and used for reinforcing the structural strength of the connecting point position, meanwhile, the reinforcing cavity is further formed between the first reinforcing plate and the bottom plate of the longitudinal beam body, the reinforcing cavity can avoid stress concentration, and the service life of the longitudinal beam assembly is prolonged. And the reliability of the longitudinal beam assembly is improved.
本发明公开了一种用于车辆的纵梁总成、车身总成及车辆。根据本发明的纵梁总成包括纵梁本体、第一加强件、第二加强件和连接件,所述纵梁本体上形成有底板;所述第一加强件和所述第二加强件设置于所述底板的两侧,所述第一加强件与所述第二加强件中的至少一个与所述底板间隔设置以形成加强腔体;所述连接件依次穿过所述第一加强件、所述底板和所述第二加强件,所述连接件的端部设置有副车架安装点。根据本发明的纵梁总成通过连接件将副车架与纵梁本体连接,并在连接点位设置第一加强板和第二加强板用于加强连接点位的结构强度,同时,第一加强板与纵梁本体的底板之间还形成有加强腔体,加强腔体能够避免应力集中,提高了纵梁总成的可靠性。
