Abstract

Mit einer Vorrichtung zum Kuppeln und Entkuppeln der Anschlußenden von Druckmittelleitungen, insbesondere von Hydraulikleitungen, mit einer ortsfesten und einer auf einem beweglichen Schlitten bewegbaren Kupplungshälfte, die in Kuppel- und/oder Entkuppelstellung bewegbar ist, insbesondere an Werkzeugschnellwechseleinrichtungen von Bau- oder Landmaschinen, soll eine Sicherung der Kupplungshälften im gekuppelten Zustand gewährleistet werden, wobei Großserien-Leitungskupplungen einsetzbar sind, so daß die Vorrichtung leicht bedienbar und kostengünstig herstellbar sowie robust und verschleißarm ist.With a device for coupling and uncoupling the terminal ends of pressure medium lines, in particular hydraulic lines, with a stationary and movable on a movable carriage coupling half, which is movable in dome and / or Entkuppelstellung, especially on quick-change tooling of construction or agricultural machinery, should a Securing the coupling halves are ensured in the coupled state, with high-volume line couplings are used, so that the device is easy to use and inexpensive to manufacture and robust and low-wear.

Dies wird dadurch erreicht, daß der Schlitten (112) durch eine Kolben-/Zylindereinheit (113,114) bewegbar und in der Kupplungsstellung durch den Druckkolben (114), dessen Druck durch ein entsperrbares Druckhalteventil (119) gehalten ist, in der Verriegelungsstellung fixierbar ist.
