The invention provides an axle end grounding device, an axle and a bogie. The shaft end grounding device comprises a sleeve, a second bearing, a frame body, a grounding ring and a second carbon brush assembly, a first mounting hole is formed in the sleeve, one side wall of the sleeve forms a first mounting wall through the first mounting hole, a second mounting hole is formed in the grounding ring, and the second mounting wall forms a second mounting wall through the second mounting hole. The second mounting hole enables one side wall of the grounding ring to form a second mounting wall, the sleeve is sleeved with an inner ring of the second bearing, the sleeve is arranged in the second mounting hole, the second mounting wall is connected with the first mounting wall in an attached mode, the outer ring of the second bearing is sleeved with the frame body, and the frame body is connected with the grounding ring in an attached mode. A collecting cavity is formed between the frame body and the grounding ring, the frame body is provided with an installation position used for installing a second carbon brush assembly, and the installation position is communicated with the collecting cavity in the radial direction. The shaft end grounding device is mounted at the end of the axle in a shaft sticking manner, so that the mounting reliability of the shaft end grounding device is improved, and the driving safety is improved.
