Abstract

L'invention concerne un ensemble embrayage permettant d'accoupler un arbre d'entrée, en particulier un vilebrequin d'un moteur de véhicule automobile, à au moins un arbre de sortie, en particulier un arbre d'entrée de boîte d'une boîte de vitesses de véhicule automobile. Ledit ensemble embrayage comporte au moins un embrayage, l'embrayage comportant un plateau de pression mobile dans la direction axiale par rapport à un contre-plateau et destiné à serrer par friction un disque d'embrayage entre le plateau de pression et le contre-plateau. Un couvercle d'embrayage destiné à recouvrir au moins en partie l'embrayage est relié au contre-plateau. De plus, un élément d'entraînement, en particulier un disque entraîneur, destiné à être relié à l'arbre d'entrée, est relié au contre-plateau. Selon l'invention, le couvercle d'embrayage et/ou l'élément d'entraînement sont centrés avec le contre-plateau au moyen d'au moins un ergot de centrage formé sur eux et introduit dans une ouverture de centrage correspondante. Il n'est ainsi pas nécessaire d'introduire une goupille d'assemblage dans des ouvertures de centrage superposées, ce qui simplifie la structure et le montage de l'ensemble embrayage.
