The invention relates to a direct-drive wheel set driving system and a bogie using the same. The direct-drive wheel set driving system comprises a driving motor, an axle and two wheels arranged on two sides of the axle, wherein a bearing component is arranged at each of two sides of the driving motor; an end cover and an inner sealing ring are arranged on one side of each bearing component; a sealing cover and an outer sealing ring are arranged on the other side of each bearing component; the end cover is connected with the inner sealing ring in a sealed mode; the sealing cover is connected with the outer sealing ring in a sealed mode; the sealing cover is fixedly connected with the end cover; and the end cover is fixedly connected with a shell of the driving motor. According to the system disclosed by the invention, the wheel set is directly driven by the motor, a gearbox and a coupling do not need to be installed, the weight of the driving system is greatly reduced, the energy utilization efficiency is improved, and the noise under the vehicle is reduced. According to a location bearing and a floating bearing, transverse movement of the stator and the rotor is released, the stress between the rotor and the stator is reduced, and the performance of the direct drive motor is guaranteed. According to the sealing structures of the bearings, the bearings have excellent sealing effects.
