Abstract

Vorgeschlagen ist ein schaltbarer Schlepphebel (1) eines Ventiltriebs einer Brennkraftmaschine. Dieser besteht aus einem Innen- und einem diesen mit seinen Armen (2) umschließenden Außenhebel (3, 4), welche Hebel (3, 4) über längs verlagerbare Koppelmittel (6) derartig miteinander verbindbar sind, dass bei Kopplung ein großer und bei Entkopplung ein kleiner Ventilhub generiert ist. Die Hebel (3, 4) verlaufen auf einer gemeinsamen Achse (5), die, in Längsrichtung gesehen, zwischen einer Komplementärfläche (11) für ein Abstützelement am Innenhebel (3) und Anlaufflächen (12, 13) für die Hubnocken an Oberseiten der Hebel (3, 4) angeordnet ist. DOLLAR A Ein derartiger Schlepphebel (1) hat aufgrund seiner nahe am Drehpunkt liegenden Achse (5) ein nur geringes Massenträgheitsmoment um diesen Drehpunkt.
