Problems solved by technology
[0003] my country's railway passenger locomotives all use asynchronous motor drive technology, such as the traditional hollow shaft six-link transmission mechanism fast passenger locomotive bogie, due to the existence of asynchronous motor drive technology gearbox transmission system, there is inevitably about 2% gear transmission efficiency At the same time, it brings problems in driving noise, lubrication, sealing, etc.
At present, there is no research work on direct drive wheel sets for locomotives at home and abroad, and the locomotive bogie technology of permanent magnet direct drive drive technology is still in a blank state

A high-power permanent magnet direct drive bogie and an express passenger locomotive. The high power permanent magnet direct drive bogie includes a frame, a wheel set, a driving mechanism, a traction mechanism, a braking mechanism and a suspension mechanism. The frame has opposite first surface and second surface, and the frame includes a pair of side beams, a plurality of beams connected between the pair of side beams and a traction beam. The driving mechanism includes a motor, a coupling and a hanging device. The motor is installed on the second surface of the frame through the hanging device. The motor is a high-power permanent magnet direct drive motor. The traction mechanism includes a traction rod, a vehicle body traction support and a bogie traction support respectively connected to two ends of the traction rod, and the bogie traction support is connected with the traction beam. The brake mechanism includes a brake and a brake disc, the brake disc is installed on the wheel, and the brake is connected with the brake disc and the beam. The suspension mechanism includes a primary suspension device and a secondary suspension device, the primary suspension device is arranged between the wheel and the second side, and the secondary suspension device is arranged on the first side.
Description
technical field [0001] The invention relates to a wheel set driving system of a rail locomotive, in particular to a high-power permanent magnet direct drive transmission mechanism. Background technique [0002] In recent years, the domestic rail transit industry and related scientific research institutions have begun to conduct research on direct drive technology. Although direct drive wheel sets with motor power less than 600kw have been used in foreign subways, light rails and high-speed rails, domestic subways, Light rail is just starting to develop work on direct drive wheelsets. [0003] my country's railway passenger locomotives all use asynchronous motor drive technology, such as the traditional hollow shaft six-link transmission mechanism fast passenger locomotive bogie, due to the existence of asynchronous motor drive technology gearbox transmission system, there is inevitably about 2% gear transmission efficiency At the same time, it brings problems of driving nois...
