Abstract

L'invention concerne un dispositif d'actionnement, destiné à un véhicule automobile, qui comprend un actionneur électromécanique doté d'un arbre qui peut être entraîné en rotation par un moteur électrique. L'arbre peut être couplé à un dispositif de déclenchement d'un embrayage par le biais d'un engrenage qui transforme un mouvement de rotation en mouvement linéaire tout en transférant une pression et/ou une traction sur un manchon de pression. Le manchon de pression agit sur un dispositif de réglage d'embrayage par le biais d'une unité d'articulation qui bloque la rotation du manchon de pression. L'invention concerne en outre un embrayage comprenant un dispositif d'actionnement de ce type.
