Abstract

Es wird eine hydraulische Anordnung (10) für ein Federungssystem beschrieben. Die Anordnung (10) umfasst einen Hydraulikzylinder (26), einen Hydrauliktank (20), ein Fördermittel (18), einen Hydraulikspeicher (48), ein Steuergerät (12), ein zwischen Hydraulikspeicher (48) und Hydraulikzylinder (26) angeordnete Lasthalteeinrichtung (32) und ein zwischen Hydraulikspeicher (48) und Steuergerät (12) angeordnetes Schaltventil (60). Um eine Federungsfunktion für den Hydraulikzylinder (26) zu ermöglichen und gleichzeitig eine Absicherung des Hydraulikzylinders (26) und des Hydraulikspeichers (48) gegen Druckabfall bei Rohrbruch zu gewährleisten, wird vorgeschlagen, das Schaltventil (60) und die Lasthalteeinrichtung (32) über eine Steuerdruckeinrichtung (70) synchron anzusteuern, wobei bei aktivierter Federungsfunktion die Lasthalteeinrichtung (32) aufgesteuert und das Schaltventil (60) in Schließstellung gebracht wird.
