Abstract
Es wird eine Messeinrichtung 1 zum Messen der aktuellen axialen Position einer innerhalb eines Dämpferzylinders 2 axial bewegbar angeordneten Kolbenstange 3 eines Schwingungsdämpfers 4 vorgeschlagen. Diese zeichnet sich dadurch aus, dass die Messeinrichtung 1 eine Übersetzungsanordnung 5 mit einer rotatorisch bewegbaren Welle 6 umfasst, wobei die Übersetzungsanordnung 5 mit der Kolbenstange 3 wirkverbunden ist und eine lineare Bewegung der Kolbenstange 3 in eine rotatorische Bewegung der Welle 6 übersetzt, sodass die aktuelle axiale Position der Kolbenstange 3 aus der aktuellen Winkelposition der Welle 6 erkennbar ist.A measuring device 1 for measuring the current axial position of a piston rod 3 of a vibration damper 4 which is arranged axially movably within a damper cylinder 2 is proposed. This is characterized in that the measuring device 1 comprises a translation assembly 5 with a rotatably movable shaft 6, wherein the translation assembly 5 is operatively connected to the piston rod 3 and translates a linear movement of the piston rod 3 in a rotational movement of the shaft 6, so that the current axial position of the piston rod 3 from the current angular position of the shaft 6 can be seen.
