The invention relates to the technical field of railway vehicle bogies, and provides a swing bolster anti-falling device, a bogie and a railway vehicle. The swing bolster anti-disengaging device comprises an anti-disengaging lifting hanger, the anti-disengaging lifting hanger comprises a first end and a second end, and the first end is fixedly connected to a bogie frame; the anti-falling lap joint seat and the swing bolster are integrally formed, and the anti-falling lap joint seat surrounds the swing bolster to form a buffer space; the anti-disengaging lap joint seat comprises a top, the anti-disengaging lifting hanger penetrates through the top of the anti-disengaging lap joint seat, and the second end is located in the buffering space and suitable for being in lap joint with the top of the anti-disengaging lap joint seat when the swing bolster falls off. The invention further provides a bogie and a railway vehicle. The defects that in the prior art, a safety steel cable connecting base increases the overall weight of a vehicle and occupies the installation space of external equipment are overcome, the function of preventing the vehicle body from falling off is achieved, and the safety steel cable connecting base has the advantages of being light in weight, high in reliability and free of occupying the external space of the vehicle body.

    本发明涉及轨道车辆转向架的技术领域,提供一种摇枕防脱装置、转向架及轨道车辆。摇枕防脱装置包括防脱提吊,防脱提吊包括第一端部和第二端部,第一端部固定连接在转向架构架;防脱搭接座,防脱搭接座与摇枕一体成型,防脱搭接座围绕摇枕形成缓冲空间;防脱搭接座包括顶部,防脱提吊穿设防脱搭接座的顶部,第二端部位于缓冲空间,第二端部适于在摇枕脱落时与防脱搭接座的顶部搭接。本发明还提供一种转向架和轨道车辆。本发明解决了现有技术中安全钢索连接座增加车辆整体重量、挤占外部设备安装空间的缺陷,不仅实现了防止车体脱落的作用,而且具有重量轻、可靠性高以及无需占用车体外部空间的特点。
