Abstract

L'invention concerne un dispositif (1) de découplage de couple et de transmission d'une force axiale d'un premier élément sur un deuxième élément. Le dispositif comprend un premier coussinet (2) pour la liaison au moins indirecte au premier élément et un deuxième coussinet (3) pour la liaison au moins indirecte au deuxième élément. Au moins un élément palier de butée (4, 5) permettant le montage rotatif des deux coussinets (2, 3) est agencé dans l'espace entre les deux coussinets (2, 3). Le premier coussinet (2) peut être soumis à l'effet d'un couple et d'une force axiale, et le deuxième coussinet (3) absorbe la force axiale sensiblement sans couple.
