Abstract

L'invention porte sur un appareil d'actionnement commandé par électricité pour un accouplement rotatif. Ledit appareil actionne un mécanisme de vis-écrou ou un mécanisme de came d'extrémité placé sur un axe de rotation de l'accouplement rotatif de manière à commander l'assemblage et le désassemblage de l'accouplement ainsi que la pression de l'accouplement grâce à une transmission différentielle à vitesse de rotation constituée de deux ensembles d'unité d'engrenage planétaire. Les avantages qui découlent de cette invention sont l'efficacité de la commande et la faible perte d'énergie de transmission.
