The invention relates to a bogie wheel set driving system and a bogie with the same. The bogie 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, wherein two sides of the driving motor are respectively provided with a bearing assembly, one of the bearing assemblies is used as a locating bearing, and the other bearing assembly is used as a floating bearing. By using the bogie wheel set driving system, 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 arrangement of the locating bearing and the floating bearing, the horizontal movement of a stator and a rotor is released, the stress between the rotor and the stator is reduced, and the performance of a direct-driving motor is ensured. Due to the adoption of sealing structures of the bearings, the bearings have better sealing effects.
