Abstract

Eine mobile Arbeitmaschine, insbesondere Flurförderzeug, weist einen Verbrennungsmotor (1) und eine davon angetriebene hydraulischen Lenkpumpe (2) zur Speisung mindestens eines Lenkaktuators (4) auf. Um die Energieverluste, die vom Lenksystem verursacht werden, zu minimieren, ist ein hydraulischer Speicher (7) an die Lenkpumpe (2) und den Lenkaktuator (4) angeschlossen und ist das spezifische Fördervolumen der Lenkpumpe (2) so bemessen, dass der Betrieb des Lenkaktuators (4) bei geringen Betriebsdrehzahlen des Verbrennungsmotors (1) das Einspeisen von Druckmittel aus der Lenkpumpe (2) und dem Speicher (7) erfordert und bei Überschreiten einer Schwellendrehzahl der Betrieb des Lenkaktuators (4) durch alleiniges Einspeisen von Druckmittel aus der Lenkpumpe (2) möglich ist. Das Volumen des Speichers (7) ist so bemessen, dass bei alleiniger Speisung des Lenkzylinders (4) durch Druckmittel aus dem vollen Speicher (7) ein mehrfaches Betätigen des Lenkaktuators (4) von Anschlag zu Anschlag möglich ist.
