  • Patent number: 9120386
    Abstract: A sensor element for a sensor device and a carbon collector includes a sensor element, in particular for energy transfer from a contact wire to a vehicle. The sensor element is formed from a fluid-sealed tube profile which can be arranged in a longitudinal recess of a carbon collector, wherein there is at least one predetermined breaking point designed on the tube profile.

  • Patent number: 9061593
    Abstract: A sliding strip and a method for producing a sliding strip for a sliding contact device which rests in a prestressed manner against an overhead wire includes a carbon molding and at least one metallic conduction device arranged in the carbon molding. The conduction device has at least one conduction layer extending on a plane transversely with respect to a sliding direction and in a direction of a prestressing force. The conduction device is formed by a layer of a metallic conductive material arranged on at least one flank of a slot which extends transversely with respect to the sliding direction in the carbon molding.

  • Publication number: 20130048458
    Abstract: The invention relates to a sliding strip (12) and to a method for producing a sliding strip (12) for a sliding contact device (10) which rests in a prestressed manner against an overhead wire (15), in particular for supplying electrical power to rail vehicles, having a carbon moulding (17) and at least one metallic conduction device, that is arranged in the carbon moulding, in order to locally increase the electrical conductivity, wherein the conduction device has at least one conduction layer (23), which extends on a plane transversely with respect to the sliding direction (18) and in the direction of a prestressing force (19), and is formed by a layer of a metallic conductive material (21), which is arranged on at least one flank of a slot (20) which extends transversely with respect to the sliding direction in the carbon moulding.

  • Patent number: 6009987
    Abstract: A slipper for current collectors having an elongated carbon brush (1) which has a hollow space surrounded on at least three sides by the brush and a carrier (3) disposed in the hollow space for supporting the carbon brush. The slipper is constructed by providing a blank of the carrier which has a cross-section that is smaller than the cross-section of the hollow space of the carbon brush. It is inserted into the hollow space and deformed so that its cross-section expands into contact with at least a portion of the surfaces of the hollow space defined by the carbon brush. An electrically conductive layer (5) can be arranged between the blank and at least a portion of the inner surfaces of the hollow space.
