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.Disclosed is a hydraulic circuit (6) for a multi-surface cylinder (2). Its piston (4) has two return surfaces (A2, A3) and an extension surface (A1). About a swing-through hydraulic machine (14), the piston of the multi-cylinder can be retracted and extended. For switching between a rapid traverse and a force passage of a piston control valves (58,64) are provided. The control valves are arranged such that for the rapid traverse a first retraction surface and the extension surface in regeneration are switchable. Furthermore, the control valves are arranged such that both retraction surfaces can be interconnected for the force passage.

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.

Furthermore, a hydraulic axle is disclosed, which is designed as a compact unit. Here, a control block (8) is provided, in which a hydraulic circuit and the hydraulic machine are arranged. To the control block then the multi-surface cylinder and a drive unit (10) are flanged for the hydraulic machine. The compact unit of the hydraulic axle can form a closed hydraulic circuit.
