The invention relates to an inner axle box hinged framework bogie and a train, the bogie comprises a wheel set, a primary suspension device, a hinged framework, a secondary suspension device and a foundation brake device, the wheel set comprises wheels, axles and axle discs, the axle discs are located on the inner sides of the wheels, the primary suspension device is arranged on the inner side of the wheel set, and the secondary suspension device is arranged on the outer side of the hinged framework. The primary suspension device comprises an axle box, a primary spring rubber pad and a primary longitudinal pull rod, the hinged framework comprises a left side beam, a right side beam and a hinged cross beam device, the left side beam is connected with the right side beam through the hinged cross beam device, and the secondary suspension device comprises an air spring, an anti-side-rolling torsion bar, an anti-snaking shock absorber, a secondary transverse shock absorber, a traction pull rod and a transverse stopper. The foundation braking device comprises a plurality of shaft disc foundation braking devices, and the foundation braking devices are located on the inner side of the hinged framework in the longitudinal direction. The inner axle box hinged framework bogie is compact in overall structure and small in self weight, curve wheel rail abrasion can be effectively reduced, and curve passing performance is improved.
