Title:
ELECTRIC CONDUCTION DEVICE AND INSULATION/SHORT-CIRCUIT CONTROL DEVICE AND SHAFT MOUNTING FIXTURE FOR TRACK MAINTENANCE VEHICLE USING THE ELECTRIC CONDUCTION DEVICE
Document Type and Number:
Japanese Patent JP2019084940
Kind Code:
A
Abstract:
To provide an electric conduction device and an insulation/short-circuit control device and a shaft mounting fixture for a track maintenance vehicle using the electric conduction device which, when an electric conduction between a shaft side and a shaft support body side occurs, is hardly affected by vibrations, and which allows stable electric conduction, excellent maintainability and simple installation.SOLUTION: An electric conduction device is mounted to a shaft and a shaft support body, and causes electric current to run between the shaft side and the shaft support body side. The electric conduction device comprises: a rotating mounted member which is mounted on the outer periphery of the shaft and rotates accompanying the rotation of the shaft; and a fixed mounted member which is arranged around the outer periphery of the shaft and fixedly held by the shaft support body, and does not rotate accompanying the rotation of the shaft. The electric conduction device has conductive contact members arranged on the rotating mounted member so as to cause the current to run between the rotating mounted member and the fixed mounted member. The electric conduction device, an insulation/short-circuit control device and a shaft mounting fixture using the electric conduction device for a track maintenance vehicle are provided.SELECTED DRAWING: Figure 1
