Abrégé
(DE)

Bei einem Getriebe mit zwei umlaufenden Getriebegliedern, die jeweils zumindest eine Lauffläche für ein umlaufendes Koppelglied aufweisen, wobei wenigstens eine Lauffläche wenigstens zwei Laufbahnen für das Koppelglied mit unterschiedlichen Laufradien aufweist und wobei die beiden Getriebeglieder über eine Verspanneinrichtung unter Einbeziehung des Koppelgliedes verspannt sind, welche die beiden Getriebeglieder mit einer variablen Anpresskraft an das Koppelglied presst, umfasst die Verspanneinrichtung eine mit einem Federelement in Reihe geschaltete Anpresseinrichtung.

(EN)

The gear system, with two conical rotating elements (4, 5) coupled by a friction ring (7), comprises a thruster unit (8) with a spring element pressing, with a variable force, the running surface of the element (4) against the friction ring.
