Contact wire for urban traffic facility

TLDR: In this paper, the contact wire of a collector shoe is suspended by a track girder through contact wire supporter 2-4 and a vibration absorber 6 is provided between a bracket 4 and the track girder 1, so that the movement of contact wire 5 to the direction of the track gate is restrained, and the contact wires does not tilt to the dead load direction.

Abstract: PURPOSE:To support the contact wire without tilting it or decreasing its damping effect, by constructing the support in the pressing direction of a collector shoe with a vibration absorbing material having a small spring constant, as well as constructing the support in the pressing direction of the tare and the support in the pressing direction of the collector shoe in the separate structure. CONSTITUTION:The contact wire 5, which is movable to the pressing direction by the collector shoe, is suspended byh a track girder 1 through contact wire supporter 2-4. A vibration absorber 6 is provided between a bracket 4 and the track girder 1, so that the movement of the contact wire 5 to the direction of the track girder 1 is restrained, and the contact wire 5 does not tilt to the dead load direction. Besides, the vibration of the contact wire 5 is absorbed, if vibrated by collector shoe as the wire rope 3 is provided in the member to support the contact wire 5 in its tare direction. Moreover, vibration of the contact wire 5 is absorbed by the vibration absorber 6 having a small spring constant, therefore, vibration of the contact wire 5 is prevented from propagating to the track girder 1.
