Abstract
(DE)
Die Erfindung betrifft einen Riemenscheibenentkoppler (1) für einen Kraftfahrzeugantriebsstrang, mit einer Nabe (2), einer eine Zugmittelaufnahmekontur (3) aufweisenden, relativ zu der Nabe (2) um eine Drehachse (4) verdrehbar aufgenommenen Zugmittelscheibe (5), mehreren die Zugmittelscheibe (5) relativ zu der Nabe (2) in einer Drehrichtung abstützenden Bogenfedern (6, 7), wobei zumindest eine erste Bogenfeder (6) in einer axialen Richtung und/oder einer radialen Richtung der Drehachse (4) versetzt zu einer parallel zu der ersten Bogenfeder (6) wirkenden, zweiten Bogenfeder (7) angeordnet ist, sowie einer mittels eines Trägers (8) drehfest mit der Nabe (2) verbundenen, auf einem hülsenförmigen Aufnahmebereich (9) des Trägers (8) aufgenommenen Schwingungstilgereinrichtung (10), wobei der Aufnahmebereich (9) des Trägers (8) einen die Zugmittelaufnahmekontur (3) unmittelbar mit ausbildenden, in der axialen Richtung verlaufenden Drehmomentübertragungsbereich (11) der Zugmittelscheibe (5) sowie zumindest eine der Bogenfedern (6, 7) in der axialen Richtung zumindest teilweise überragt.
