Abstract: The invention relates to a device for fastening a sliding element to a current collector or to a rocker mounted thereto, to draw electrical energy from an overhead contact line to an electrically driven vehicle. The device comprises a sliding element, a carrier, a carbon contact piece arranged on the carrier, and a fastening point for fastening the sliding element to the current collector is formed between the sliding element and the current collector. At each fastening point between the sliding element and the current collector, a detent assembly is arranged on the side of the sliding element and, for each detent assembly, a receptacle for the detent assembly is arranged on the side of the current collector. Each detent assembly and the receptacle associated therewith are releasably brought into engagement with each other by inserting and locking the detent assembly in the receptacle.

Abstract: Devices for discharging ground currents, more particularly in wind turbines, from electrical machines. The devices have a grounding ring mounted on a rotor of the electrical machine and a sliding contact connectable to ground and that is in contact with the grounding ring. The sliding contact element has a carbon brush with a bulk density between 1.1 and 1.4 g/cm3, and the carbon brush contains a metal inclusions composed of silver, the silver proportion being between 1 and 8%.

Abstract: The invention relates to a method for producing a connection between a carbon strip and a metal mounting of a bow contact for current collectors by means of an adhesive containing electrically conductive particles. The method is characterized in that the adhesive contains 40 to 50 parts by weight of a first adhesive component on the basis of a phenolic resin, 5 to 20 parts by weight of a second adhesive component on the basis of an epoxy resin, and 40 to 50 parts by weight of conductive particles.

Abstract: The invention relates to a sensor device for indicating wear states on contact bodies of pantographs of electrically driven vehicles, said contact bodies being fixed to metallic supports. The aim of the invention is to provide a sensor device that permits, at practically any location on the contact strip, the installation of signal transmitters that can indicate the respective wear state of the contact strip without interrupting the driving operation. To this end, the invention employs the use of a sensor device characterized in that it is comprised of blind holes (3) made in the contact bodies (2), of transmission channels (6) that are connected to the blind holes (3), and of a monitoring unit, whereby the blind holes (3) and monitoring unit are connected via the transmission channels (6).
