The invention provides a single wheel set bogie frame, a bogie and a railway vehicle, and belongs to the technical field of railway vehicles. The single wheel set bogie frame comprises two side beams, two end beams and two longitudinal beams, and the two side beams are arranged in parallel at intervals; the two end beams are connected between the ends, on the same side, of the two side beams respectively and are arranged in parallel; the middle parts of the two end beams are sunken downwards to form sunken parts; the two longitudinal beams are parallel to the side beams and located in a space defined by the two end beams and the two side beams; and the two ends of the longitudinal beams are connected with the two end beams respectively, and the connecting portions of the two longitudinal beams and the end beams are located on the two sides of the sunken parts respectively. According to the single wheel set bogie frame provided by the invention, the overall strength of the frame is improved; the sunken parts increase a force transmission path, so that the overall stress of the end beams can be relieved, and meanwhile, a deformation space is provided for torsion and transverse and vertical bearing of the end beams; and the sunken parts can lower the center-of-gravity position of the frame, and the running stability of the vehicle is improved.

    本发明提供了一种单轮对转向架构架、转向架及轨道车辆,属于轨道车辆技术领域,包括两个侧梁、两个端梁及两个纵向梁,两个侧梁间隔且平行设置;两个端梁分别连接在两个侧梁同侧的端部之间,且相互平行设置;两个端梁的中间部位均向下凹陷形成下凹部;两个纵向梁与侧梁平行设置,并位于两个端梁以及两个侧梁围成的空间内;纵向梁的两端分别与两个端梁连接,且两个纵向梁与端梁的连接部位分别位于下凹部的两侧。本发明提供的单轮对转向架构架,提升了该构架的整体强度;下凹部增大了力的传递路径,可以减缓端梁整体受力,同时也为端梁扭转及横向竖向承载提供变形空间;下凹部还可以降低构架的重心位置,提升车辆运行平稳性能。
