The invention discloses a railway wagon, a bogie and a swing bolster tapered wedge assembly thereof. The swing bolster wedge assembly comprises a swing bolster and tapered wedges arranged on the two sides of the end of the swing bolster. Swing bolster inclined planes matching the tapered wedge inclined planes are arranged on two sides of the end part of the swing bolster; one of the swing bolsterinclined plane and the tapered wedge inclined plane is provided with a limiting groove, the other one of the swing bolster inclined plane and the tapered wedge inclined plane is provided with a limiting protruding edge matching the limiting groove, and the two side walls of the limiting protruding edge match the two side walls of the limiting groove in the transverse direction so that the taperedwedge can be limited to rotate around the longitudinal direction and rotate around the vertical direction relative to the swing bolster. The swing bolster tapered wedge assembly can improve the rhombus deformation resistance of the bogie. According to the swing bolster tapered wedge assembly, with the limiting protruding edges and the limiting grooves, the tapered wedges synchronously rotate in the vertical direction along with the swing bolster and cannot independently rotate in the vertical direction and the longitudinal direction, so that the rhombus deformation resistance of a bogie is improved to a large extent through the swing bolster tapered wedge assembly.

    本发明公开了一种铁路货车、转向架及其摇枕斜楔组件,摇枕斜楔组件包括摇枕和设置在摇枕的端部两侧的斜楔,摇枕的端部两侧设有与斜楔斜面配合的摇枕斜面,所述摇枕斜面和所述斜楔斜面,一者设有限位凹槽,另一者设有与所述限位凹槽适配的限位凸棱,所述限位凸棱的两侧壁与所述限位凹槽的两侧壁沿横向相互配合,以限定所述斜楔绕纵向转动和相对所述摇枕绕竖直方向转动。该摇枕斜楔组件能够提升转向架抗菱形变形的能力。该摇枕斜楔组件通过设置限位凸棱和限位凹槽,可以保证斜楔随摇枕同步绕竖直方向转动,而不会独自绕竖直方向和独自绕纵向转动,这样,可以保证摇枕斜楔组件很大程度上提升转向架的抗菱形变形能力。
