Abstract

The invention discloses a axle end power generation structure of a railway vehicle, which comprises a bearing saddle, a guard ring and a generator, wherein the bearing saddle has a cylindrical surfacestructure, the side surface of the bearing saddle comprises an annular mounting surface, and the mounting surface is used for mounting the generator; the guard ring is disposed at a gap between the bearing saddle and the axle bearing, and the inner circle of the guard ring is matched with the outer circle clearance of the axle bearing; and the generator comprises a stator and a rotor, the statoris fixed on the mounting surface, and the rotor is fixed on the axle end. The axle end power generation structure which can be applied to the railway vehicle by using a three-piece bogie has the advantages of being high in reliability, high in protection, small in size, light in weight, maintenance-free and small in bogie change.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to an axle end power generation structure of a railway vehicle. Background technique [0002] With the increase of operating speed and load of railway vehicles, more and more electrical devices are widely used in railway vehicle systems, but limited by the structural characteristics and working environment of railway vehicles, traditional power supply methods are difficult to implement . Common power generation schemes for railway vehicles in the prior art include various power generation methods such as installing storage battery devices, shaft-end pulley drive generator generators, solar power generators, wind power generators, and bearing generators. Due to the limitation of technical level, the above power generation methods have relatively large shortcomings in terms of reliability, power generation, service life, and harsh working environment. Compared with the abov...
