Abstract

Die Erfindung beschreibt eine vollvariable Hubventilsteuerung einer Brennkraftmaschine wobei die Hubventilsteuerung (Fig. 1) über ein Antriebsmittel (1) verfügt, welches Antriebsmittel eine Schwingbewegung mindestens eines Schwinghebel (2) um eine Lagerachse C3 bewirkt, wobei der Schwinghebel (2) mit einer Laufrolle (2b) versehen ist, welche Laufrolle (2b) mit einer Lauffläche (5d) mindestens eines Kulissenhebel (5) in Wirkverbindung steht, welcher Kulissenhebel um eine Lagerachse C4 schwenkbeweglich gelagert ist, wobei die Lauffläche (5d) des Kulissenhebel (5) aus einer Leerhubsektion (5a), über eine Anlauframpe (5b) in eine Hubsektion (5c) übergeht und der Kulissenhebel weiter mit einer Druckfläche (5e) versehen ist, wobei die Druckfläche (5e) über ein zwischengeschaltetes Übertragglied (6) auf mindestens ein Hubventil (8) einwirkt und des weiteren ein Verstellmittel (3, 4) vorgesehen ist, mit welchem Verstellmittel (3, 4) die Position der Lagerachse C4 definiert im Kreisbogen um die Lagerachse C3 veränderbar ist, und damit der Wirkanteil der Hubsektion (5c) des Kulissenhebel (5) während der Auslenkung des Schwinghebels (3) bestimmt, und damit sowohl die Öffnungsdauer, als auch die Hubhöhe des beaufschlagten Hubventil variiert werden kann.
