Abstract

L'invention concerne un disque d'embrayage pour un dispositif d'embrayage à friction ainsi que le dispositif d'embrayage à friction lui-même, et une chaîne cinématique. Le disque d'embrayage (30) comprend un moyeu (32) destiné à être raccordé de manière solidaire en rotation à un arbre, un élément de friction (33) pour l'introduction d'un couple par liaison par friction dans le disque d'embrayage (30) ainsi qu'une première bride de moyeu (40) et une deuxième bride de moyeu (41), au moins la première bride de moyeu (40) étant raccordée de manière solidaire en rotation au moyeu (32), et le disque d'embrayage (30) présentant des éléments ressorts (50), entre les deux brides de moyeu, qui accouplent celles-ci mécaniquement l'une à l'autre, de telle sorte que les brides de moyeu puissent être déplacées l'une par rapport à l'autre par rotation, le disque d'embrayage (30) étant conçu de telle sorte que les deux brides de moyeu (40, 41) puissent être décalées latéralement l'une par rapport à l'autre. Grâce au disque d'embrayage selon l'invention, un décalage latéral ou radial ou un déplacement radial peuvent être compensés, tout en assurant simultanément une longue durée de vie du fait de conditions de friction réduites au niveau des ressorts d'amortissement du disque d'embrayage.
