Abstract
A central traction device for a straddling monorail train includes a traction pin and a traction beam. A central sleeve is provided at the center of the traction beam, and the traction pin is mounted in the central sleeve. An inner cavity of the central sleeve has a corset-shaped structure having large diameters on an upper end and a lower end and a small diameter at a middle part, forming double tapered bevels, and a resilient rubber bush is provided between an inner wall of the central sleeve and the traction pin. The device has a simple and compact overall structure and facilitates connection and separation between the train body and the bogie; by providing the lift assembly, the traction device is fixedly connected to the frame, thus the traction device can be wholly lifted; and operation process and environment of raising and lowering the vehicle are improved.
