The invention relates to the technical field of railway vehicles, and provides a railway vehicle bogie frame, a bogie and a railway vehicle. The railway vehicle bogie frame comprises two side beams, a first cross beam, a second cross beam and two air spring supporting seats. The two side beams are arranged in parallel, and each side beam is provided with a first mounting hole and a second mounting hole. The first cross beam and the second cross beam are arranged in parallel, the two ends of the first cross beam are arranged in the first mounting holes of the two side beams in a penetrating mode respectively and located on the outer sides of the two side beams respectively, the two ends of the second cross beam are arranged in the second mounting holes of the two side beams in a penetrating mode respectively, and the two ends of the second cross beam are located on the outer sides of the two side beams respectively. The two air spring supporting seats are arranged on the outer sides of the two side beams respectively, and each air spring supporting seat is installed between the first cross beam and the second cross beam. Wheels of the railway vehicle are suitable for being installed on the outer sides of the two side beams. And the weight of the framework is reduced, so that the framework has the advantages of light weight, strong curve trafficability and the like.

    本发明涉及轨道车辆技术领域,提供一种轨道车辆转向架构架、转向架及轨道车辆。该轨道车辆转向架构架包括两个侧梁、第一横梁、第二横梁和两个空簧支撑座。两个侧梁平行设置,各侧梁分别设置有第一安装孔和第二安装孔。第一横梁和第二横梁平行设置,第一横梁的两端分别穿设于两个侧梁的第一安装孔内,且第一横梁的两端分别位于两个侧梁的外侧,第二横梁的两端分别穿设于两个侧梁的第二安装孔内,且第二横梁的两端分别位于两个侧梁的外侧。两个空簧支撑座分别设于两个侧梁的外侧,各空簧支撑座安装于第一横梁和第二横梁之间。其中,轨道车辆的车轮适于安装于两个侧梁的外侧。减轻了构架的重量,使构架具有重量轻、曲线通过能力强等优点。
