Abstract

Die Erfindung betrifft ein hydrostatisches Antriebssystem (1) mit mindestens einem an eine Pumpe angeschlossenen Verbraucher, wobei zur Steuerung des Verbrauchers eine mittels eines Ansteuersignals betätigbare Steuerventileinrichtung (3; 4; 5; 6) vorgesehen ist und eine Förderstromregeleinrichtung (11) von einem Lastdrucksignal des Verbrauchers beaufschlagbar ist und wobei das Antriebssystem eine Sicherheitseinrichtung (20) aufweist, mittels der die Beaufschlagung der Steuerventileinrichtung (3; 4; 5; 6) mit dem Ansteuersignal und die Beaufschlagung der Förderstromregeleinrichtung (11) mit dem Lastdrucksignal steuerbar ist, wobei die Sicherheitseinrichtung (20) eine Funktionsstellung (21b) aufweist, in der das Ansteuersignal an die Steuerventileinrichtung (3; 4; 5; 6) und das Lastdrucksignal an die Förderstromregeleinrichtung (11) geführt ist, und eine Sicherheitsstellung (21a) aufweist, in der die Steuerventileinrichtung (3; 4; 5; 6) von dem Ansteuersignal und die Förderstromregeleinrichtung von dem Lastdrucksignal entlastet ist. Hinsichtlich der verbesserten Handhabung und eines einfachen An- bzw. Abkoppelns der Verbraucher wird vorgeschlagen, dass die Sicherheitseinrichtung (20) mit einer Entlastungstellung (21c) versehen ist, in der die Verbindung der Steuerventileinrichtung (3; 4; 5; 6) mit dem Verbraucher entlastbar ist.
