The invention relates to the technical field of railway vehicles, and provides a framework, a bogie and a railway vehicle. The framework comprises a top plate, two web plates, two side plates and a bottom plate. The top plate is recessed from the two ends to the central axis. The two webs are connected to the two sides of the top plate in the width direction respectively, the upper surfaces of the webs are matched with the top plate, and the middles of the lower surfaces of the webs extend in the direction away from the top plate to form extending sections. The two side plates are connected to the two sides of the top plate in the length direction respectively and connected with the lower surfaces of the two web plates respectively, bending parts are constructed at the positions, at the extending sections, of the side plates, and the bending parts are connected with the extending sections. And the bottom plate is connected with the two web plates and the two side plates. The Y-shaped framework is formed in the mode, the structure of the framework is more compact, the occupied space is smaller, meanwhile, use of structural parts such as plates and beams is reduced, and the weight of the framework is greatly reduced.
本发明涉及轨道车辆技术领域,提供一种构架、转向架及轨道车辆。该构架包括顶板、两个腹板、两个侧板和底板。顶板由两端至中轴线的方向下凹。两个腹板分别连接于顶板宽度方向的两侧,腹板的上表面与顶板相适配,腹板下表面的中部朝远离顶板的方向延伸,并形成有延伸段。两个侧板分别连接于顶板长度方向的两侧,且两个侧板分别与两个腹板的下表面相连,侧板在延伸段的位置处构造有折弯部,折弯部与延伸段相连。底板与两个腹板和两个侧板相连。通过上述方式形成“Y”字形的构架形式,使构架的结构更加紧凑、占用空间更小,同时减少板、梁等结构件的使用,极大地降低了构架的重量。
