The invention discloses a vehicle lower cross beam assembly and a railway vehicle, the vehicle lower cross beam assembly comprises two vehicle lower cross beam bodies, the vehicle lower cross beam bodies at least comprise cross beam vertical plates, a first display plate and a second display plate, the number of the vehicle lower cross beam bodies is two, the cross beam vertical plates of the two vehicle lower cross beam bodies are attached and welded, and the end parts of the cross beam vertical plates are used for being welded to boundary beams of a vehicle chassis; at least one of the two vehicle lower cross beam bodies is used for being connected with equipment to be hoisted, and the reinforcing piece is connected to the vehicle lower cross beam hoisting body and connected with the first display board and the second display board of the vehicle lower cross beam hoisting body. The vehicle lower cross beam assembly is provided with the two vehicle lower cross beam bodies, and the two vehicle lower cross beam bodies are arranged back to back, so that the cross beam vertical plates of the two vehicle lower cross beam bodies are attached to each other and fixed through welding, the two vehicle lower cross beam bodies are connected into a whole, and the strength and rigidity of the vehicle lower cross beam assembly are improved to a great extent. And the hoisting point is forcefully reinforced through the reinforcing piece, so that the hoisting risk is reduced.

    本申请公开了一种车下横梁组件及轨道车辆,包括:车下横梁体,车下横梁体至少包括横梁立板以及第一展板和第二展板,车下横梁体为两个,两个车下横梁体的横梁立板贴合并焊接,横梁立板的端部用于焊接于车辆底架的边梁;补强件,两个车下横梁体中的至少一者用于与待吊装设备连接,补强件连接于车下横梁吊装体上,且分别与车下横梁吊装体的第一展板和第二展板连接。本申请具有两个车下横梁体,并将两个车下横梁体背对背设置,使得两个车下横梁体的横梁立板相贴合,并通过焊接进行固定,使得两个车下横梁体被连接为一体,很大程度上增加了车下横梁组件的强度和刚度。通过补强件强有力地对吊点处进行了增强,降低了吊装风险。
