The embodiment of the invention provides a framework, a bogie and a railway vehicle, and the framework comprises side beams and cross beams; the side beam comprises a side beam upper cover plate, a side beam lower cover plate, a side beam inner vertical plate and a side beam outer vertical plate, the part, exceeding the side beam inner vertical plate, of the inner side of the side beam upper cover plate serves as a side beam upper connecting end, and the part, exceeding the side beam inner vertical plate, of the inner side of the side beam lower cover plate serves as a side beam lower connecting end; the cross beam comprises a cross beam upper cover plate, a cross beam lower cover plate and a cross beam outer vertical plate, and the parts, exceeding the cross beam upper cover plate, of the two ends of the cross beam outer vertical plate serve as cross beam connecting ends, are inserted between the side beam upper connecting ends and the side beam lower connecting ends and are connected with the side beam inner vertical plates; the cross beam upper cover plate is in butt joint with the side beam upper connecting end, and the cross beam lower cover plate is in butt joint with the side beam lower connecting end. According to the framework provided by the embodiment of the invention, the size and weight of the side beams can be reduced, and the lightweight design of the bogie can be realized.
本申请实施例提供一种构架、转向架及轨道车辆,其中,构架包括:侧梁和横梁;侧梁包括:侧梁上盖板、侧梁下盖板、侧梁内立板和侧梁外立板,侧梁上盖板的内侧超出侧梁内立板的部分作为侧梁上连接端,侧梁下盖板的内侧超出侧梁内立板的部分作为侧梁下连接端;横梁包括:横梁上盖板、横梁下盖板和横梁外立板,横梁外立板的两端超出横梁上盖板的部分作为横梁连接端,插入侧梁上连接端和侧梁下连接端之间并与侧梁内立板相连;横梁上盖板与侧梁上连接端对接相连,横梁下盖板与侧梁下连接端对接相连。本申请实施例提供的构架能减小侧梁的体积及重量,有利于实现转向架的轻量化设计。
