Electric driving device of rail transport vehicle

The utility model belongs to the technical field of railway track driving equipment, and particularly relates to a track transport vehicle electric driving device which comprises a driving unit and a braking unit which are arranged in a split mode and connected in a traction mode. Each of the driving unit and the braking unit comprises a basic driving module and a walking module; the driving unit further comprises a guide frame arranged on the bottom side of the main machine frame, and a center guide wheel is installed on the guide frame. The brake unit further comprises brake frame structures arranged at the front end and the rear end of the main machine frame. According to the electric driving device, the hydraulic motor is adopted to drive the friction driving wheel, so that the rail transport vehicle is driven through friction reaction force, and compared with a traditional mechanical transmission mode, the electric driving device has the higher energy utilization rate, and therefore energy consumption is
