Embodiment Construction

[0023] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] See figure 1 , figure 2 , image 3 As shown, the present invention relates to an axle-end disc type permanent magnet power generation device for railway freight cars. The power generation device mainly includes three parts: a stator structure, a rotor structure and an axle box end cover (10). The stator structure and the rotor structure are respectively a single stator, a Disc structure with single rotor, where:

[0025] Such as image 3 As shown, the stator structure adopts a stator core disk (8), which is formed by stacking punched silicon steel sheets, and a coil (9) is wound on the stator core disk to generate an induced current. The stator core plate (8) is fixed on the inner boss of the axle box end cover (10) by screws (11), which is safe and reliable.

[0026] Such as figure 1 , Picture 1-1 , figure 2 As shown, the rotor st...

Abstract

The invention discloses a railway wagon axle end disk-type permanent magnet generation device. By the aid of the structural characteristics of a rapid freight transport bogie with an axle box device, an axle end pressing plate and an axle box cover structure are changed without changing the size and the mounting mode of an existing bearing, and the permanent magnet generation device is mounted in the rapid freight transport bogie. The permanent magnet generation device is provided with a single stator-rotor disk-type structure, a permanent magnet is used for excitation, the structure is simple, an axle box is small in size, and a rotor is connected with an axle end through screws. When a wagon runs, an axle rotates, and the generation device generates electric energy. The supply power of the generation device can meet the electricity demands of an electronic anti-skid device for a disk brake of the bogie and an online monitoring system for a running gear. The axle end disk-type permanent magnet generation device is integrally sealed in an axle box end cover and is resistant to impact vibration, hermetic, dustproof and waterproof, and a stator device and a rotor device are easily arranged and conveniently mounted and dismounted.

Description

technical field [0001] The invention relates to an axle-end disc type permanent magnet power generation device for railway freight cars, and relates to a novel power source structure, which can provide electric energy for related equipment on the bogie and an on-line monitoring device when the train 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 railway fr...
