    摘要： An axle box suspension positioning device for a railway vehicle is provided according to the present application, which includes a guide column assembly. The guide column assembly includes a fixed end connected to a frame of the railway vehicle, and a free end which is extendable and retractable from an opening of the axle box. An elastic positioning component is provided in the opening, and the elastic positioning component limits a movement of the free end along a running direction of the vehicle with respect to the frame. The arrangement of the elastic positioning component enables the axle box suspension positioning device to have a large positioning rigidity. A bogie having the axle box suspension positioning device is further provided according to the present application.

    摘要： The disclosure discloses a swing bolster, a swing bolster vibration reduction assembly and a bogie. The swing bolster includes a body, wherein a mounting cavity for mounting a friction block is formed in two ends of the body; the mounting cavity is provided with a first horizontal opening and a second horizontal opening, which are opposite to each other; and opening directions of the first horizontal opening and the second horizontal opening are perpendicular to an extending direction of the body. The friction block is not matched with the swing bolster through slopes, and a movement direction of the swing bolster is perpendicular to a movement direction of the friction block relative to the swing bolster, so that a vibration reduction effect of the bogie in an unloaded state is ensured, and using reliability of the swing bolster is ensured.

    摘要翻译： 本公开公开了一种摇摆垫，摆动减振组件和转向架。 摇摆架包括主体，其中用于安装摩擦块的安装腔形成在主体的两端; 安装腔设置有彼此相对的第一水平开口和第二水平开口; 并且第一水平开口和第二水平开口的打开方向垂直于主体的延伸方向。 摩擦块通过斜坡与摆臂不匹配，摆动摇摆的移动方向垂直于摩擦块相对于摇摆板的移动方向，从而在无负载状态下转向架的减振效果 确保摆臂的可靠性。
