The invention relates to a motor direct-driving bogie comprising a framework, wherein the framework is provided with a traction device, a foundation brake device, a secondary spring and a wheel set driving system; the wheel set driving system comprises a driving motor, an axle passing through a central hole formed in the driving motor and two wheels arranged at two sides of the axle; the framework comprises side beams located at two sides and a beam fixedly connected with the side beams located at two sides, and the bottoms of the side beams are fixedly provided with supporting plates; and the foundation brake device is fixedly arranged on the supporting plates and the side beams. By using the motor direct-driving bogie, a wheel set is directly driven by the motor, and a gearbox and a shaft coupling are not needed to be mounted, so that the weight of the driving system is greatly reduced, the energy utilization efficiency is increased, and the noise under a vehicle is reduced. Due to the adoption of a fixing way of the foundation brake device, the load of the beam is reduced, and the stress of the framework is more reasonable.
