The invention discloses a permanent magnet direct drive bogie with built-in axle boxes, and particularly relates to the field of railway vehicle bogies. The permanent magnet direct drive bogie with the built-in axle boxes comprises a framework device integrally in an H shape, and the framework device comprises a pair of side frames arranged in parallel and a pair of transverse frames arranged on the inner sides of the side frames in parallel; traction rods are arranged between the transverse frames, axle box devices are arranged at the bottoms of the side frames, and secondary suspension devices are arranged in the middle of the side frames. Wheels are arranged at the front ends and the rear ends of the side frames respectively, axles are arranged between the wheels, hollow couplings sleeve the middle sections of the axles, axle box devices sleeve the positions, close to the two ends of the hollow couplings, of the axles respectively, the hollow couplings are fixedly connected with the axles, and the axle box devices are rotationally connected with the axles. The hollow coupler is sleeved with a permanent magnet motor and connected with the permanent magnet motor, and the permanent magnet motor is fixedly connected with the framework device. The permanent magnet direct drive bogie is compact in structure and light in self weight, meanwhile, it is guaranteed that the train has good stability and damping effect.
