The invention discloses an automobile engine compartment longitudinal beam assembly which comprises a longitudinal beam body, an outer lining plate and an engine bracket rear mounting plate, the outer lining plate and the engine bracket rear mounting plate are arranged on the left side and the right side of the longitudinal beam body respectively, and the longitudinal beam body comprises an engine compartment edge beam rear section and a reinforcing assembly. The engine compartment edge beam rear section comprises a horizontal beam and a bent beam arranged on the front side of the horizontal beam, the bent beam is bent upwards from back to front, and the reinforcing assembly is connected with the horizontal beam and the bent beam at the same time. According to the longitudinal beam assembly of the automobile engine compartment, the bending and torsional rigidity of the longitudinal beam body can be improved, the longitudinal beam body is prevented from being broken, the vertical pendulum mode of the engine compartment is enhanced, the Z-direction dynamic rigidity of mounting points such as a cooling module, an engine suspension and a shock absorber is facilitated, and the rigidity and strength of a rear mounting plate of an engine bracket are guaranteed. And the safety and the universality can be improved.
本发明公开了一种汽车发动机舱纵梁总成,包括纵梁主体、外衬板和发动机托架后安装板,所述外衬板和所述发动机托架后安装板分别设置在所述纵梁主体的左右两侧,所述纵梁主体包括发动机舱边梁后段和加强组件,所述发动机舱边梁后段包括水平梁和设置在所述水平梁的前侧的弯曲梁,所述弯曲梁从后至前向上弯曲,所述加强组件同时与所述水平梁以及所述弯曲梁连接。本发明提供的一种汽车发动机舱纵梁总成,能够提升纵梁主体的抗弯抗扭刚度,防止纵梁主体断裂,增强发动机舱的垂摆模态,有利于冷却模块、发动机悬置以及减震器等安装点的Z向动刚度,保证发动机托架后安装板的刚强度,还能够提升安全性和通用性。
