The invention discloses a rear longitudinal beam assembly and a vehicle. The rear longitudinal beam assembly comprises a rear longitudinal beam body, the rear longitudinal beam body is a U-shaped groove with an opening facing the outer side and comprises a top plate, a bottom plate and a side plate connected with the top plate and the bottom plate, and a mounting protrusion extending upwards is integrally formed in the middle section of the top plate. A first mounting hole for fixing the shock absorber and a plurality of first reinforcing ribs penetrating through the top surface and the side surface of the mounting bulge are arranged on the mounting bulge; and an inwards-concave receding groove is formed in the position, corresponding to the mounting bulge, of the side plate, and a receding notch is formed in the position, corresponding to the receding groove, of the bottom plate. The problems that an existing sheet metal rear longitudinal beam is poor in manufacturability, low in structural strength and large in weight can be solved.

    本发明公开了一种后纵梁总成及车辆,包括后纵梁本体,所述后纵梁本体为开口朝向外侧的U型槽,包括顶板、底板以及连接顶板和底板的侧板,所述顶板中段一体成型有朝上延伸的安装凸起,所述安装凸起上设有用于固定减震器的第一安装孔和贯穿安装凸起顶面和侧面的多条第一加强筋;所述侧板在与安装凸起对应的位置设有朝内凹陷的避让槽,所述底板在与避让槽对应的位置设有避让缺口。其能够解决现有的钣金后纵梁工艺性差、结构强度低、重量大的问题。
