Abstract

Der Erfindung liegt die Aufgabe zugrunde, eine Ventiltriebsanordnung für eine Brennkraftmaschine der gattungsgemäßen Art zu schaffen, mit der ein sicheres Verbinden eines Festnockens (2) mit einem drehbar auf der Nockenwelle gelagerten Nocken (3) erfolgt und mit der Fehlfunktionen vermieden werden. Erfindungsgemäß ist im Bereich des Grundkreises (14) des drehbar auf der Nockenwelle (1) gelagerten Nockens (3) eine nutförmige Führung (8) angeordnet, mit der ein in einer Sacklochbohrung (17) des Grundkreises (14) des drehfest mit der Nockenwelle (1) verbundenen Nockens (2) gelagerter und gesteuert verschiebbarer Vorverriegelungskolben (6) in und außer Eingriff bringbar ist. Die nutförmige Führung, (8) in der der Vorverriegelungskolben einrasten kann, erstreckt sich im Grundkreis (14) des drehbar gelagerten Nockens (1) um ca. 180°.
