Abstract

Ein Axialkraftaufnehmer weist einen zur Krafteinleitungsachse rotationssymmetrischen, eine Messfeder bildenden Verformungskörper (1) und paarweise in Bereichen entgegengesetzt gerichteter Dehnung angeordnete, zu einer elektrischen Widerstandsbrücke geschaltete Dehnungsmessstreifen (15, 18) auf. Der Verformungskörper (1) hat eine bei Axialkraft radial gedehnte zentrische Aufnahmebohrung (8), deren Bohrungsrand (12) über eine Ringzarge (10) mit einer in axialem Abstand zur Aufnahmebohrung (8) angeordneten Verformungsscheibe (13) verbunden ist. Deren Scheibenrand (14) springt über die Ringzarge (10) radial vor. Die Dehnungsmessstreifen (15, 18) sind stirnseitig auf der Verformungsscheibe (13) paarweise innerhalb und außerhalb des Durchmessers der Ringzarge (10) appliziert.
