The invention relates to a railway vehicle shaft end grounding device, a bogie and a railway vehicle, and belongs to the technical field of railway vehicles. The railway vehicle shaft end grounding device comprises a friction disc and a grounding body; wherein one end of the friction disc is mounted on a bogie shaft end, is fixedly connected with the bogie shaft end and rotates along with a wheel shaft; the grounding body is used for conducting current to the friction disc, and comprises a brush holder arranged above the friction disc, and a plurality of first spaces are formed in the brush holder; the end cover sleeves the center of the brush carrier and forms a second space with the brush carrier; the carbon brush is installed in the first space, one end of the carbon brush is in sliding contact with the friction disc, the other end of the carbon brush is connected with the carbon brush wire, the carbon brush wire is located in the second space, and a wire connecting device on the carbon brush wire fixedly installs the carbon brush on the end cover through a first fastening device. And the spring is located in the second space, is fixedly connected with the end cover, is in contact with the carbon brush, and is used for pressing the carbon brush and providing support for the carbon brush to move up and down. According to the railway vehicle shaft end grounding device, the mechanical structure is simplified, the safety and reliability of a product are improved, and the structure of the product is more compact.
