AN EDDY CURRENT CLUTCH TO ENHANCE COOLING OF ENGINE COOLING WATER IN DIESEL ELECTRIC LOCOMOTIVES

摘要

The present invention relates to an eddy current clutch to enhance cooling of engine cooling water in diesel electric locomotives, comprising an inner rotor disposed into an outer rotor, the inner rotor rotating inside the outer rotor maintaining a small gap in-between; an engine providing mechanical power to a horizontal shaft for axial movement, the horizontal shaft having two end- bearings disposed in respective housing; the outer rotor rotating when an eddy current generated through rotation of the inner shaft maintaining said gap; a spiral bevel gear arrangement transmitting motion between the inner and the outer shaft intersecting at a 90° angle; a vertical shaft movable vertically corresponding to the axial movement of said horizontal shaft, the vertical shaft provided with a pair of tapered bearing on both sides; a radiator fan operating to cool the engine cooling water, the rotation of the radiator fan is interdependent with the vertical movement of the vertical shaft; and a slip ring enabled to provide a closed loop speed regulation by varying the clutch current, application of a direct current in the field coils of the inner rotor producing a magnetic field that determines the torque rate from the engine to be transmitted to the output rotor.
