Abstract

Lineareinheit zur Erzeugung einer mechanischen Kraft durch Druckluft, die im wesentlichen aus einem kolbenstangenlosen Pneumatikzylinder (1) mit einem Gleitstück (2) besteht, das über eine Führungsschiene (3) am Zylinder (1) geführt ist und das mit einem innenliegenden Kolben des Pneumatikzylinders (1) in Verbindung steht, so dass das Gleitstück (2) in Abhängigkeit einer wechselseitigen Beaufschlagung des innenliegenden Kolbens hin- und herbewegbar ist, wobei Positioniermittel zum Stoppen der Linearbewegung des Gleitstücks (2) in zumindest einer vorbestimmten Stelle vorgesehen sind, die aus einem Positioniermodul (7) mit zumindest einem bewegbaren Halteelement (8a, 8b) bestehen, welches am Gleitstück (2) befestigt ist, wobei das mindestens eine Halteelement (8a, 8b) des Positioniermoduls (7) mit zumindest einer parallel zur Führungsschiene (3) am Pneumatikzylinder (1) angeordnete Anschlagstange (9) zusammenwirkt, wobei die Anschlagstange (9) an zumindest einem Ende mit Stoßdämpfermitteln ausgestattet ist, um die beim Stoppen der Linearbewegung des Gleitstücks (2) auftretende Stoßbeanspruchung zu absorbieren.
