Claims

[Claims for Utility Model Registration] (1) At least one of the left and right axles, which are integrally formed through the axle, is electrically connected by interposing an insulator between the inner ring member and the outer ring member. It consists of insulated wheels, with sliding contact devices interposed in the parts of both left and right wheels that are always electrically connected to the track.
An insulating/short-circuit device for a railway working vehicle, characterized in that the two left and right sliding contact devices are electrically connected via an electric wire and an on/off switch provided on the main body of the working vehicle. (2) A sliding contact device whose base end is attached to the vehicle body and whose tip comes into contact with the vicinity of the outer periphery of a railway wheel, preferably with the outer periphery of the wheel, wherein the tip comes into contact with the base of the wheel. It is supported so as to be movable toward and away from the wheel side around the support portion on the end side, and is interposed between the member side having the tip portion supported so as to be movable toward and away from the vehicle body and the vehicle body side. The tip is configured to be pressed toward the wheel side by a spring, and a cylindrical body is provided at the tip so that the axis is approximately perpendicular to the contact surface on the wheel side. A current collector rod that comes into contact with the side is slidably inserted in the longitudinal direction of the current collector rod, and a spring having non-linear spring characteristics with the base end held on the cylindrical body side is arranged on the base end side of the current collector rod. A sliding contact device for a railway working vehicle, characterized in that the current collector rod is configured to be pressed against the wheel side.
