Abstract

L'invention concerne un procédé de variation d'une pression dans un maître-cylindre (9) en sortie d'un engrenage comportant un planétaire intérieur (1) en entrée de l'engrenage entraîné par un moteur (5) et un ensemble d'au moins deux satellites (2) rattachés à un porte satellite (3) formant une sortie de l'engrenage de type planétaire et un planétaire extérieur (4). Il est exercé un frottement sur le planétaire extérieur (4) régulé selon une pression en sortie de l'engrenage représentative du couple délivré par l'engrenage de type planétaire, une variation du frottement entraînant une variation de couple en sortie de l'engrenage de type planétaire, le frottement exercé diminuant avec une augmentation de la pression en sortie de l'engrenage de type planétaire.
