Abstract

Der Nockenwellenversteller hat einen Schwenkmotor (1), der einen drehfest mit einer Nockenwelle (6) verbundenen Rotor (3) aufweist. Dieser ist relativ zu einem ihn umgebenden Stator (2) drehbar. Um den Nockenwellenversteller so auszubilden, daß bei einfachem Aufbau eine kostengünstige Montage gewährleistet ist, ohne die Funktionsfähigkeit des Nockenwellenverstellers zu beeinträchtigen, weist die Nockenwelle (6) einen Form- und/oder Kraftschlußteil auf, auf dem der Rotor (3) mit einem Grundkörper (7) drehfest sitzt. Sein Innendurchmesser ist größer als der Durchmesser eines die Nocken der Nockenwelle (6) umschreibenden Kreises. Der Schwenkmotor (1) kann axial über die Nocken hinweg auf den Form- und/oder Kraftschlußteil aufgeschoben werden. Die Nockenwelle (6) benötigt daher nur noch zwei Lagerstellen. Der Nockenwellenversteller läßt sich einfach und kostengünstig montieren und eignet sich für Kraftfahrzeuge.

Figure 00000001
The camshaft adjuster has a swivel motor (1) which has a rotor (3) connected in a rotationally fixed manner to a camshaft (6). This is rotatable relative to a surrounding stator (2). To the camshaft adjuster in such a way that with a simple construction, a cost-effective assembly is ensured without affecting the functionality of the camshaft adjuster, the camshaft (6) has a positive and / or frictional engagement on which the rotor (3) with a main body ( 7) rotatably seated. Its inside diameter is larger than the diameter of a circle circumscribing the cams of the camshaft (6). The swivel motor (1) can be pushed axially over the cams on the form and / or adhesion part. The camshaft (6) therefore requires only two bearings. The camshaft adjuster can be mounted easily and inexpensively and is suitable for motor vehicles.
