Abstract

L'invention concerne un actionneur (11) pour le blocage et/ou la libération d'un embrayage (4) d'un pignon fou agencé sur un arbre d'une boîte de vitesses manuelle. L'actionneur comprend un actionneur à rampe (13), qui est agencé entre un manchon coulissant (12) monté en rotation et l'embrayage. Le manchon coulissant porte sur sa périphérie extérieure une coulisse annulaire avec laquelle il est en contact actif au moyen d'un contour sélecteur.
