The invention discloses a railway vehicle bogie. The bogie is arranged in an internal axle box manner, and frameworks are supported on the inner sides of wheel sets, so the axle length is effectivelyshortened, the unsprung mass and dead weight of the bogie are reduced, and the curve passing performance is improved; the arrangement of downward concave sections of side beams and the connection of cross beams to the downward concave sections can effectively reduce the height of the gravity center of the bogie and reserve a high longitudinal space for a vehicle body, and web plates and cover plates can be adopted to enhance the strength of the side beams and improve the bearing capacity of the side beams; two primary positioning components are adopted for positioning, so that the axle distance of the bogie can be further reduced; and a secondary suspension device is additionally arranged to improve the vertical and transverse performances of the bogie and increase the running speed of thebogie, and secondary spri
