L'invention concerne un amortisseur de vibrations en torsion, en particulier un volant d'inertie divisé, qui présente au moins deux masses d'inertie (2, 3) qui peuvent tourner en opposition à la résistance d'au moins deux éléments déformables (7, 8) d'accumulation d'énergie, en particulier des ressorts hélicoïdaux de compression accouplés l'un à l'autre par au moins un dispositif d'accouplement (24), qui, lorsqu'un premier élément (7) d'accumulation d'énergie se déforme et en particulier est détendu, a pour effet un entraînement contrôlé d'un deuxième élément (8) d'accumulation d'énergie et qui présente au moins un premier et un deuxième dispositifs d'entraînement (27, 28). Pour éviter des secousses indésirables lors du fonctionnement d'un véhicule automobile équipé de l'amortisseur de vibrations en torsion, le premier dispositif d'entraînement (27) est accouplé au premier élément coulissant d'accouplement (32) qui lui-même est accouplé au premier élément (7) d'accumulation d'énergie, et le deuxième dispositif d'entraînement (28) est accouplé à un deuxième élément coulissant d'accouplement (32) qui lui-même est accouplé au deuxième élément (8) d'accumulation d'énergie.
