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. A hydraulic arrangement (10) for a suspension system is described. The arrangement (10) comprises a hydraulic cylinder (26), a hydraulic tank (20), a conveying means (18), a hydraulic accumulator (48), a control device (12), a load-holding device (47) arranged between the hydraulic accumulator (48) and the hydraulic cylinder (26). 32) and between hydraulic accumulator (48) and control unit (12) arranged switching valve (60). In order to enable a suspension function for the hydraulic cylinder (26) and at the same time to ensure protection of the hydraulic cylinder (26) and the hydraulic accumulator (48) against pressure drop at pipe break, it is proposed, the switching valve (60) and the load holding device (32) via a control pressure device (70) to control synchronously, wherein when the suspension function is activated, the load holding device (32) is opened and the switching valve (60) is brought into the closed position.
