Embodiment Construction

[0022] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0023] See figure 1 , The present invention relates to a power supply device at the shaft end of a railway express freight vehicle. As a generator, the power supply device mainly includes three parts: a stator structure, a rotor structure and an axle box end cover (7), wherein:

[0024] figure 1 and Picture 1-1 The stator structure adopts a stator with salient poles, and a stator core (6) is formed by stacking punched silicon steel sheets, and a trapezoidal coil (13) is wound on the stator core 6 to generate an induced current. The stator core 6 (that is, the silicon steel sheet group) is fixed inside the axle box end cover (7) through the stator pressure plate (14) and its screws (15), which is safe and reliable.

[0025] The rotor structure adopts an outer rotor, which is excited by permanent magnets. Its structure includes a rotor outer cylin...

Abstract

The invention discloses an axle end power device for a rapid railway freight vehicle, and aims to provide stable and reliable power for an electronic anti-skid device and an online monitoring system of a rapid freight vehicle bogie with an axle box. The axle end power device for the railway freight vehicle is designed for the structural characteristics of an axle box body of the freight vehicle bogie, and consists of two parts, i.e. a permanent magnet rotor and a stator coil. A permanent magnet excitation mode is adopted for the rotor. An outer permanent magnet rotor structure is connected with the end part of a vehicle axle through a screw. The rotor coil and an end cover of the axle box are combined into a whole. When the vehicle runs, the power device generates electric energy. The power supply power of the designed power device is 50 to 200W, so that the power consumption requirements of the electronic anti-skid device and the online monitoring system of the rapid freight vehicle are met. The axle end power device is integrally sealed in the end cover structure of the axle box, so that the power device is resistant to vibration and high in dustproof and waterproof performance; and the power device is easy to mount and convenient to disassemble.

Description

technical field [0001] The invention relates to a power supply device at the shaft end of a railway express freight vehicle, which relates to a novel power supply structure, which can provide power for an electronic anti-skid device and an on-line monitoring system of a express vehicle bogie when the vehicle is running. Background technique [0002] With the continuous development of railway freight transportation, the speed of freight trains continues to increase, and the requirements for the safety of express freight vehicles and bogies are getting higher and higher. On the one hand, components with higher safety and reliability, such as electronic anti-skid devices, Disc brake system, etc., and at the same time, it is required to provide real-time monitoring solutions in the safety monitoring of the running system to improve the prediction ability of safety accidents such as train derailment. However, due to the need for continuous dismantling and marshalling of general r...
