Abstract

Für eine Anordnung einer Nockenwelle im Zylinderkopf einer Brennkraftmaschine, bei der die im Zylinderkopf über ein mit einem Spurlager kombiniertes Gleitlager angeordnete Nockenwelle mit einem hydraulisch gesteuerten Phasensteller ausgerüstet ist, dem über einen Wellenbund der Nockenwelle mit Umfangsnuten ein Hydraulikmedium gesteuert zugeführt ist, wird vorgeschlagen, dass der in einem geteilt ausgebildeten Gehäuse angeordnete Wellenbund ein integriert angeordnetes Gleitlager mit Spurlager umfasst mit beiderseits des Gleitlagers ausgebildeten axialen Spurlager-Anschlagflächen in gegenüber dem Gleitlager-Durchmesser größeren Ausnehmungen im Gehäuse, in die die Nockenwelle mit im Durchmesser angepassten Wellenbund-Abschnitten mit Umfangs- bzw. Radialspiel derart eingreift, dass die in den Wellenbund-Abschnitten angeordneten Umfangsnuten lediglich zur jeweiligen äußeren Stirnseite des Gehäuses hin in den Ausnehmungen abgedichtet sind.
