The invention relates to the technical field of railway vehicles, and discloses a frame, a bogie and a railway vehicle. The frame comprises a frame body, a walking wheel mounting seat and a first vibration reduction unit, the walking wheel mounting seat is used for mounting walking wheels, the frame body and the walking wheel mounting seat can rotate relatively, and the walking wheel mounting seat is connected with the first vibration reduction unit and is subjected to vibration reduction through the first vibration reduction unit. In the actual operation process of the vehicle frame, the walking wheels can be installed on the walking wheel installation bases, and therefore vibration generated by unevenness of the track beam wheel body supporting face can be attenuated through the first vibration reduction units, and the riding comfort of a railway vehicle is improved.
本发明涉及轨道车辆技术领域,公开一种车架、转向架和轨道车辆。车架包括架体、行走轮安装座及第一减振单元,所述行走轮安装座用于安装行走轮,所述架体与所述行走轮安装座能够相对转动,所述行走轮安装座与所述第一减振单元连接且通过所述第一减振单元减振。该车架在实际运行过程中,行走轮可以安装在行走轮安装座上,这样,来自轨道梁轮体支撑面的不平度产生的振动可以通过第一减振单元得到衰减,以提高轨道车辆的乘坐舒适性。
