Abstract[German]
In einem Sperrdifferential (1) wird ein Sperrmoment durch die Verdrehung von Rampenringen (11, 12) gegeneinander eingestellt. Ein elastisches Element (15) koppelt die Rampenringe (11, 12) aneinander und bewirkt eine Rückstellkraft auf die Rampenringe (11, 12), die eine passive Selbstöffnung des Sperrdifferentials (1) unterstützt.[English]
In a locking differential (1), a locking torque is set by the rotation of ramp rings (11, 12) with respect to one another. An elastic element (15) couples the ramp rings (11, 12) to one another and exerts a restoring force on the ramp rings (11, 12), which restoring force supports passive self-opening of the locking differential (1).[French]
L'invention concerne un différentiel à verrouillage (1) dans lequel un couple de verrouillage est réglé par la rotation de bagues de rampe (11, 12) l'une par rapport à l'autre. Un élément élastique (15) accouple les bagues de rampe (11, 12) l'une à l'autre et exerce une force de rappel sur les bagues de rampe (11, 12), ladite force de rappel assistant une auto-ouverture passive du différentiel à verrouillage (1).
