The invention discloses an inner axle box bogie for a railway vehicle, which comprises a framework, a wheel set, a foundation brake device, a traction device, a secondary suspension device and a primary suspension device, and is characterized in that the framework comprises two groups of cross beams and a group of longitudinal beams for connecting the two groups of cross beams; the cross beams arearranged over the axle, and the longitudinal beam is connected between the middles of the two cross beams. The two ends of each cross beam are each provided with a small longitudinal beam, and the small longitudinal beams are installation parts and connectors for primary suspension. The primary suspension device comprises an axle box, a primary spring and a primary vertical shock absorber; wherein the two groups of wheel sets comprise an axle and two wheels; a secondary steel spring assembly, a secondary vertical shock absorber and two sets of anti-side-rolling torsion bars are arranged in the middle of the longitudinal beam. The bogie has the characteristics that all parts of the bogie except for wheel disc braking can be placed on the inner side of the wheel set, so that the purpose ofremarkably reducing the weight of the bogie is achieved, and the running performance of the whole bogie is improved.
