Force measuring cell, contact force measuring device and method for measuring the contact force between a current collector and a current supply line

摘要

the kraftmesszelle (6) with at least one wall (63), with a paragraph (66) ground floor (62) and one with an opening (67), its lid (64) oversight. this is a stabfu00f6rmiges kraftu00fcbertragungsmittel (37) through the opening (67) to (66) erstreckbar.further, a tension in the kraftu00fcbertragungsmittel (37) between (66) and a lid (64) by means of a befestigungsmittels (65) erzeugbar and used (65) within the kraftmesszelle (6) on kraftu00fcbertragungsmittel (37) that is appropriatefrom that it used (65) in the direction of the longitudinal axis of the kraftu00fcbertragungsmittels (37) on the lid (64) ausu00fcbbar.moreover, the (66) with at least one dehnungssensor (61), in the kraftu00fcbertragungsmittel (37) outgoing krafteinfluss is compressed, and the at least one wall (63) with at least one dehnungssensor (61), in the kraftu00fcbertragungsmittel (37) outgoing kraftei nfluss is stretched, accident.the kontaktkraftmesseinrichtung a pantograph (3) has at least one schleifleiste (310) and a wippenrahmen (33).it includes at least one than dehnungssensor trained load sensor (41) for fast kraftu00e4nderungen, at least one erfindungsgemu00e4u00dfe kraftmesszelle (6) for static forces between schleifleiste (310) and wippenrahmen (33) and an evaluation unit for determining a common me sssignals.in the process, the analog measured values are digitized and the digital by means of a complementary filterpaar filtered and exported to a common messsignal added.
