The invention relates to the technical field of railway vehicles, and provides a railway vehicle steering framework, a bogie and a railway vehicle, and the railway vehicle steering framework comprises two side beams, a cross beam and two air spring supporting seats. The two side beams are arranged in parallel. The cross beam is arranged between the two side beams, and a center pin installation channel used for being connected with a center pin is formed in the middle of the cross beam. The two air spring supporting seats are arranged on the sides, away from each other, of the two side beams respectively. Wheels of the railway vehicle are suitable for being installed on the outer sides of two side beams, each side beam is provided with an installation hole, a connecting piece is arranged in each installation hole in a penetrating mode, one end of each connecting piece is located on the inner side of the corresponding side beam and forms a gearbox hanging seat, and the other end of each connecting piece is located on the outer side of the corresponding side beam and is connected with a tread sweeper installation seat and a brake installation seat. The capacity of the railway vehicle passing through a small-radius curve is improved, the mass of the bogie is reduced, the running quality of the railway vehicle is improved, and the framework structure is more compact.

    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、转向架及轨道车辆,该轨道车辆转向架构包括两个侧梁、横梁和两个空簧支撑座。两个侧梁平行设置。横梁设于两个侧梁之间,横梁的中部形成有用于连接中心销的中心销安装通道。两个空簧支撑座分别设于两个侧梁远离彼此的一侧。其中,轨道车辆的车轮适于安装于两个侧梁的外侧,各侧梁分别设有安装孔,安装孔内穿设有连接件,连接件的一端位于侧梁的内侧,并形成齿轮箱吊座,连接件的另一端位于侧梁的外侧,并连接有踏面清扫器安装座和制动安装座。提升轨道车辆通过小半径曲线的能力、降低转向架的质量、改善轨道车辆运行品质、使构架结构更加紧凑。
