Abstract
The present invention relates to a flexible direct-drive bogie and implements a flexible frame by using a flexible cross beam, so as to make it easy for left and right side-frames to nod relatively to adapt to a larger twist of a track. As the frame is flexible, a primary suspension of the present invention is simplified to a thin layer of rubber pad, so that the production cost is reduced. Flexible drive devices enable flexible suspension of a permanent magnetic motor, and at the same time, can transmit torque, improve transmission efficiency, and reduce a weight of a transmission mechanism.
