Abstract

Offenbart ist eine Ventilanordnung zur Ansteuerung eines Hubwerks eines landwirtschaftlichen Nutzfahrzeugs mit zumindest einem Hubzylinder. Dieser hat zwei von einem Hubkolben getrennte Zylinderräume. Der erste Zylinderraum ist über eine herkömmliche und seit Jahren aus dem Stand der Technik bekannte EHR (elektronisch-hydraulische Hubwerksregelung für Traktoren) über eine erste Arbeitsleitung verbunden. Mit der EHR ist eine Druckbeaufschlagung und Druckentlastung des Hubkolbens über den ersten Zylinderraum ermöglicht, womit ein Hubwerk steuerbar ist. Zusätzlich ist der zweite Zylinderraum, insbesondere zum druckunterstützten Senken, über eine Ventilsteuerung (36) mit einem Druck beaufschlagbar.
