The invention relates to the technical field of railway vehicles, and provides an end underframe and a railway vehicle. The end underframe comprises a traction beam, a coupler mounting seat, a bufferbeam and a sleeper beam. The traction beam comprises two traction beam webs, the upper side of each traction beam web is connected with an upper flange, the lower side of each traction beam web is connected with a lower flange, and the outer side of each traction beam web is provided with a first reinforcing plate. Buffer beam connectors are formed among the first ends of the traction beam webs, the first ends of the upper turned edges, the first ends of the first reinforcing plates and the first ends of the lower flanges, sleeper beam connectors are formed among the second ends of the traction beam webs, the second ends of the lower flanges, the second ends of the first reinforcing plates and the connecting pieces, and a coupler mounting base is connected between the two traction beam webs. A buffer beam is connected with the buffer beam connectors, and a sleeper beam is connected with the sleeper beam connectors. The structure space occupied by the traction beam is reduced, and the space connector requirement of coupler installation and the space limiting area requirement of the bogie can be met at the same time.
本发明涉及轨道车辆技术领域,提供一种端部底架及轨道车辆。该端部底架包括牵引梁、车钩安装座、缓冲梁和枕梁,牵引梁包括两个牵引梁腹板,各牵引梁腹板的上侧分别连接有上翻边,各牵引梁腹板的下侧分别连接有下翻边,各牵引梁腹板的外侧分别设有第一补强板,牵引梁腹板的第一端、上翻边的第一端、第一补强板的第一端以及下翻边的第一端之间形成缓冲梁接口,牵引梁腹板的第二端、下翻边的第二端、第一补强板的第二端以及连接件之间形成枕梁接口,车钩安装座连接在两个牵引梁腹板之间,缓冲梁与缓冲梁接口相连,枕梁与枕梁接口相连。本发明减小了牵引梁所占用的结构空间,能够同时满足车钩安装的空间接口要求和转向架空间限制区域要求。
