A direct-drive wheel bogie drive systems and applications of the system

The present invention relates to a direct-drive wheel bogie drive systems and applications of the system, including a drive motor, the axle, the two wheels disposed on either side of the axle, a bearing assembly are provided on both sides of the drive motor, a bearing assembly and an inner side is provided with a cap seal ring, the other side of the bearing assembly is provided with a closure and an outer ring, the inner ring seal connecting cap, the sealing cap sealingly connected to the outer ring, the fixed cover and the cover connector, the housing cover is fixedly connected to the drive motor. The present invention achieves a direct motor drive wheel pair, without having to install gear and coupling, greatly reducing the weight of the drive system, to improve the energy use efficiency and reduce the noise under the car. By providing locating bearing and a floating bearing, a stator, and the release of the lateral movement of the rotor, reduces stress between the rotor and the stator, to ensure that the direct drive motor performance. Of the sealing structure of the bearing, the bearing has a better sealing effect.
