Abstract

The invention relates to a permanent magnet direct drive locomotive and a drive suspension damping device thereof. The damping device comprises a suspension rod assembly, a suspension arm and a flexible plate diaphragm. A first rotating shaft is arranged in a first rubber joint of the suspender assembly in a penetrating mode, a second rotating shaft is arranged in a second rubber joint in a penetrating mode, and the suspender assembly can be connected with a driving motor through the first rotating shaft and can be connected with a frame through the second rotating shaft; the suspension arm can be connected with a drive through the base and can be connected with a frame through a third rotating shaft; a transmission disc is arranged at the first end of a hollow shaft of a rotor of the driving motor, and a plurality of first disc claws extend out of the transmission disc. A force transmission disc is arranged at the second end of the hollow shaft, and a plurality of second disc claws extend out of the force transmission disc; the flexible plate membrane is used for being arranged on the side, away from the second grabbing disc, of the first disc claw, the transmission pin is arranged on the side, away from the first disc claw, of the flexible plate membrane, and the transmission pin and the first disc claw are arranged on the flexible plate membrane in a staggered mode.

Description

technical field [0001] The present disclosure relates to the technical field of railway locomotives, in particular, to a permanent magnet direct drive locomotive and a drive suspension vibration damping device thereof. Background technique [0002] Permanent magnet direct drive technology is a recognized next-generation drive technology in the railway locomotive industry. The advantages of permanent magnet synchronous motors, such as high power density, high power factor, and high overload capacity, make permanent magnet system research and development a new generation of rail transit equipment research trend. The permanent magnet direct drive traction system adopts the permanent magnet synchronous motor to directly drive the wheel set technology, and the gearbox is eliminated. This transmission mode has the advantages of simple structure, high transmission efficiency, green energy saving, etc., and is the development direction of the next generation locomotive traction drive...
