DIRECT DRIVEN TRACTION MOTOR FOR UPGRADING MAINTENANCES OF RAILROAD CAR

摘要

The present invention relates to a railway vehicle traction motors directly drive enhances the maintainability and the balance at the bottom of the rail cars traction motor stator fixed to the direct drive motor provided on the towing; Is configured to include a permanent magnet rotor which is provided to directly drive the inner traction motors; Is configured to be integrated with the rotor inside the traction motor axle being formed to a predetermined length protrudes directly drive traction motor directly drives the traction motor housing; Traction motor-side coupling is fastened to the inner ends of the traction motor axle; Inside the outer bearings and axle bearings for railway vehicle is fixed to the bottom of the balance that is configured to support the outer axle and bogie axles; And is fastened to the outer ends of the axle for coupling the axle and adapted to couple to traction motor side coupling; includes According to the present invention as described above, by providing a railway vehicle bogie of the coupling between each axle and the shaft of the direct drive traction motor, from the balance wheel as is conventional, depending on the maintenance is possible to separate from the traction motor directly drives only the balance the axle, it is difficult and you need to remove the effect of both direct drive traction motor to simplify the cumbersome process of improving the maintainability. ;
