PROBLEM TO BE SOLVED: To enable easy attachment to an axle without the need for winding a secondary winding to the axle which has been attached to a track maintenance vehicle.SOLUTION: A short-circuit/insulation changeover device of an insulated wheel comprises a solenoid attached to a vehicle body side, a magnetic movable body (adsorption body) which is attached to an axle side, and can rotate together with the wheel, and a changeover switch which operates when the adsorption body is sucked by the solenoid. The adsorption body can be attached to the axle while surrounding an external periphery of the axle, the solenoid is excited when being fed with power by an operation of a power feed switch, and the excitation is released when the power feed is stopped. The adsorption body is apart from the solenoid at the non-excitation of the solenoid, and when the solenoid is excited, the adsorption body is sucked to the solenoid, and approximates the solenoid, however, does not contact with the solenoid. The changeover switch can switch a short circuit and insulation of an inner ring and an outer ring by the approximation and separation of the adsorption body to/from the solenoid.SELECTED DRAWING: Figure 1

    【課題】 保線車両に取付け済みの車軸に二次巻線を巻く必要がなく、車軸に手軽に取付け可能にする。【解決手段】 車体側に取付けられるソレノイドと、車軸側に取付けられて車軸と共に回転可能な磁性可動体(吸着体)と、吸着体がソレノイドにより吸引されると作動する切替えスイッチを備え、前記吸着体は車軸の外周を囲んで車軸に取付けることができ、ソレノイドは給電スイッチの操作により給電すると励磁され、給電を停止すると励磁が解除され、吸着体はソレノイドの非励磁時はソレノイドから離れており、ソレノイドが励磁されるとソレノイドに吸引されてソレノイドに接近するが接触はせず、切替えスイッチはソレノイドへの吸着体の接近、離れにより内輪と外輪の短絡と絶縁の切替えが可能な絶縁車輪の短絡・絶縁切替え装置である。【選択図】図1
