Abstract

Die Erfindung betrifft eine Arbeitsmaschine, insbesondere für Tiefbauarbeiten, mit einem auswechselbaren, druckmittelangetriebenen Werkzeug (4), bei der für die Auswechslung des Werkzeugs (4) ein Schnellwechsel-Kupplungssystem (1) angeordnet ist, welches eine mechanische Kupplung (2) und wenigstens eine Fluidkupplung (3;5) aufweist, wobei an der maschinenseitigen Kupplung einerseits und am Werkzeug (4) andererseits je eine Kupplungskomponente (31,32; 51,52) der wenigstens einen Fluidkupplung (3;5) in einer derartigen Relativstellung angeordnet sind, daß sie bei eingerasteter mechanischer Kupplung (2) einander in vorbestimmtem Abstand gegenüber liegen, und wobei wenigstens eine der Kupplungskomponenten in Richtung auf die andere Kupplungskomponente zur Erzielung der Schließstellung der Kupplung (3;5) bewegbar ist. Hierbei zeichnet sich die Arbeitsmaschine dadurch aus, daß jeder Einzelanschluß der Fluidkupplung (3;5) separat betätigbar ist, und daß die Kupplungskomponenten (31,32; 51,52) zum Ausgleich von Fluchtungsfehlern insbesondere durch Gelenklager lageeinstellbar gehalten sind. Damit wird eine vollautomatische und zuverlässige Ankopplung auch bei Fluchtungs- oder Toleranzfehlern der Kupplungskomponenten möglich.
