Abstract

Eine Nockenwelle für eine Verbrennungskraftmaschine weist eine Trägerwelle (1) und Steuernockenbereiche (2) auf, in denen jeweils nur die exzentrische Ventilsteuerfläche (4) an einem Nockenelement (5) vorgesehen ist, nicht hingegen der Schließstellungsanschlag (3) für ein in die Schließstellung beaufschlagtes Ventilstellglied (8). Die Nockenelemente (5) stehen axial von Haltekörpern (6) ab, die auf der Trägerwelle (1) axial neben dem Steuernockenbereich (2) drehfest fixiert sind. Weiters sind Ventiltriebe mit derartigen Nockenwellen beschrieben.
