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

Abstract

The invention discloses a high-power permanent-magnet direct-drive bogie and a rapid passenger locomotive. The high-power permanent-magnet direct-drive bogie comprises a framework, a wheel set, a drive mechanism, a traction mechanism, a brake mechanism and a suspension mechanism. The framework is provided with a first surface and a second surface which are opposite. The framework comprises a pairof side beams, a plurality of cross beams connected between the pair of side beams and a traction beam. The driving mechanism comprises a motor, a coupler and a hanging device, wherein the motor is installed on the second surface of the framework through the hanging device, and the motor is a high-power permanent-magnet direct-drive motor. The traction mechanism comprises a traction rod, a vehiclebody traction support and a bogie traction support, wherein the vehicle body traction support and the bogie traction support are connected to the two ends of the traction rod respectively. The bogietraction support is connected to the traction beam. The brake mechanism comprises a brake and a brake disc, wherein the brake disc is installed on a wheel, and the brake is connected with the brake disc and the cross beams. The suspension mechanism comprises a primary suspension device and a secondary suspension device, wherein the primary suspension device is arranged between the wheel and a second side face, and the secondary suspension device is arranged on a first side face.

Description

technical field [0001] The invention relates to a wheel set drive system of a rail locomotive, in particular to a 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 noise, lubrication, sealing and so...
