Abstract

Offenbart ist eine hydraulische Schaltung (6) für einen Mehrflächenzylinder (2). Dessen Kolben (4) hat zwei Rückzugsflächen (A2, A3) und eine Ausfahrfläche (A1). Über eine durchschwenkbare Hydromaschine (14) kann der Kolben des Mehrfachzylinders ein- und ausgefahren werden. Zum Umschalten zwischen einem Eilgang und einem Kraftgang eines Kolbens sind Steuerventile (58,64) vorgesehen. Die Steuerventile sind dabei derart angeordnet, dass für den Eilgang eine erste Rückzugsfläche und die Ausfahrfläche in Regeneration schaltbar sind. Des Weiteren sind die Steuerventile derart angeordnet, dass für den Kraftgang beide Rückzugsflächen zusammenschaltbar sind.
Des Weiteren ist eine hydraulische Achse offenbart, die als kompakte Baueinheit ausgebildet ist. Hierbei ist ein Steuerblock (8) vorgesehen, in dem eine hydraulische Schaltung und die Hydromaschine angeordnet sind. An den Steuerblock sind dann der Mehrflächenzylinder und eine Antriebseinheit (10) für die Hydromaschine angeflanscht. Die kompakte Baueinheit der hydraulischen Achse kann einen geschlossenen hydraulischen Kreislauf bilden.
