Abstract

L'invention concerne un palier d'actionnement d'embrayage qui est actionné par une bague d'actionnement. Selon l'invention, une bride annulaire en saillie radiale vers l'extérieur est formée sur une zone terminale de la bague extérieure de roulement, ladite zone terminale étant tournée vers le dispositif embrayage en position montée. Sur cette bride annulaire, repose une section surface d'appui d'une bague d'actionnement. La bague externe de roulement est ainsi sollicitée en traction principalement dans la direction axiale.
