Abstract

The invention relates to the technical field of double-track trains, and puts forward a bogie. The bogie comprises a framework and a first suspension mechanism, wherein the first suspension mechanismis installed on the framework and comprises a first mounting seat, a second mounting seat, elastic components, first stopping rods and second stopping rods; the second mounting seat is installed on the framework; the elastic components are connected between the first mounting seat and the second mounting seat; the first stopping rods are fixed on the first mounting seat and extend towards a direction of the second mounting seat; and the second stopping rods are fixed on the second mounting seat, extend towards a direction of the first mounting seat and are coaxially arranged with the first stopping rods. By use of the bogie, the elastic components perform a vibration attenuation function, and the compression degree of the elastic components is large under a situation that vibration amplitude is large, at the time, the first stopping rods and the second stopping rods are abutted, so that the elastic components prevent from being excessively compressed, and therefore, the stability of the bogie is improved.

Description

technical field [0001] The invention relates to the technical field of double-track trains, in particular to a bogie. Background technique [0002] In recent years, in order to improve system efficiency, save energy and reduce noise, a lot of research has been done on permanent magnet direct drive traction systems. In the field of rail transportation, research and exploration on permanent magnet traction systems have been launched. With the improvement of the cost performance of permanent magnet materials and the continuous improvement of control systems, permanent magnet traction systems will appear on more rail trains. [0003] At present, direct-drive bogie technology is mainly used in the fields of bullet trains, subways, intercity, low-floor, etc., with power ranging from 46.6kW to 720kW, and the single-axle power is relatively small, so it is not suitable for high-power locomotives. The unreasonable setting of the suspension mechanism leads to low stability of the bog...
