Abstract

Freilaufkupplung mit einem Kranz von in einem Ringspalt (16) aufgenommenen Klemmelementen (18) und einem Laufring (14), der den Ringspalt begrenzt und eine Klemmkontur für die Klemmelemente bildet, dadurch gekennzeichnet, dass ein die Klemmelemente (18) haltender Käfig (20) und ein koaxial zu dem Laufring (14) angeordnetes Axiallager (36) in einer gemeinsamen, im Durchmesser abgestuften Hülse (28) aufgenommen sind, die einen Abschnitt mit kleinerem Durchmesser, an deren innerem Umfang die Klemmkontur gebildet ist, und einen Abschnitt (30) mit größerem Durchmesser hat, der das Axiallager (36) aufnimmt, und dass die Klemmelemente (18) mit ihren inneren Scheiteln eine zylindrische Fläche definieren, deren Durchmesser mit dem Innendurchmesser eines Innenrings (42) des Axiallagers (36) übereinstimmt.
