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 an insulator, an end cover, a friction disc, a carbon brush assembly and an elastic piece; wherein the first end of the insulator is fixedly connected with a vehicle body; a first cavity is formed in the insulator, and two ends of the first cavity are opened; the end cover is fixedly connected to the opening of the first end of the insulator; the friction disc is mounted between the bogie shaft end and the insulator, is fixedly connected with the bogie shaft end and rotates along with the axle; the carbon brush assembly is mounted in the first cavity, and one end is in contact with the friction disc; the carbon brush assembly comprises a first carbon brush and a second carbon brush, and the first carbon brush and the second carbon brush are concentrically arranged; the elastic piece is installed in the first cavity, one end abuts against the carbon brush assembly, and the other end abuts against the end cover. And the elastic piece is matched with the carbon brush assembly. The railway vehicle shaft end grounding device can reduce the production cost, and improve the assembly efficiency and the product quality.
