The embodiment of the invention provides a bogie frame, a bogie and a railway vehicle, a side beam upper cover plate and a side beam lower cover plate of the bogie frame protrude out of a side beam vertical plate along the transverse inner side and form a bearing connector, and the bearing connector is provided with a connecting bent plate and connected with the side beam upper cover plate, the side beam lower cover plate and the side beam vertical plate. Meanwhile, the transverse direction of the connecting bent plate and the side beam vertical plate are provided with a gap to form a double-inner-cavity structure with the side beam, so that the longitudinal rigidity of the side beam is improved, the strength of the connecting part of the side beam and the cross beam is improved, the high-speed operation requirement is met, and the safety of the framework is improved.
本申请实施例中提供了一种转向架构架、转向架及轨道车辆,转向架构架的侧梁上盖板和侧梁下盖板沿横向内侧凸出侧梁立板并形成承接接口,承接接口设有连接弯板,并分别与侧梁上盖板、侧梁下盖板和侧梁立板连接,同时连接弯板的横向与侧梁立板设有间隔与侧梁形成双内腔结构,由此以提高侧梁的纵向刚度,同时提高侧梁和横梁连接部分的强度,使其适应高速运行需求,并提高构架的安全性。
