Shaft-end permanent magnet power generation device and bogie comprising same

Abstract

The invention provides a shaft-end permanent magnet power generation device and a bogie comprising the same. The shaft-end permanent magnet power generation device comprises a stator assembly and a rotor assembly, wherein the rotor assembly is installed at the shaft end of a rotating shaft of the bogie and rotates along with the rotating shaft, the stator assembly is fixedly installed on a frame body of the bogie, a working space with an adjustable radial and / or axial distance is formed between the stator assembly and the rotor assembly, and the relative position of the stator assembly and the rotor assembly meets a corresponding requirement for generating electromagnetic induction current. The shaft-end permanent magnet power generation device of the invention has the advantages of small axial size, small volume, convenience in disassembly and assembly, low production cost, high reliability, simplicity in maintenance, strong practicability, no change of the original internal structure of an axle and the like, and realizes the purpose of converting mechanical energy into electric energy.

Description

technical field [0001] The invention relates to the technical field of power generation of railway vehicles, in particular to an axle end permanent magnet power generation device and a bogie containing the power generation device. Background technique [0002] The speed of rail trains is constantly breaking through, and the energy consumption is also increasing. In order to ensure the stable operation of the train, meet the overall power supply needs of the train, make full use of the kinetic energy of the train, and improve the transportation efficiency, a reasonable and practical bogie is designed. The shaft end power generation device is of great significance. [0003] In the prior art, the installation of the power generation device on the bogie needs to be arranged separately on the bogie, and the belt drive is used, so the bogie shaft needs to be designed separately; since the motor cannot be centrally symmetrical on the bogie, it is difficult to match its dynamic para...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the installation of the power generation device on the bogie needs to be arranged separately on the bogie, and the belt drive is used, so the bogie shaft needs to be designed separately; since the motor cannot be center-symmetrical on the bogie, it is difficult to match its dynamic parameters

At the same time, due to the increase of the sprung mass of the motor, the dynamic performance of the bogie will become worse

Moreover, the bogie with the power generation device on the bogie is generally a passenger car bogie, and its frame is an integral structure that can be fixed and installed; The bogie power generation unit cannot be installed

[0004] The patent "Axle End Disc Permanent Magnet Generating Device for Railway Freight Cars (Patent No.: 201210561240.X)" installs the generating device on the axle of the train, which solves the problem that the generating device occupies a large space on the bogie, the shaft is designed separately, and the steering of the truck However, the device covers the stator structure and rotor structure inside the axle box end cover, and is fixedly connected with the axle box bearing seat sleeved on the axle through the axle box end cover. For the installation basis, this structure makes the axle box bearing seat, stator structure, rotor structure and axle diameter need to be used together
