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.The invention relates to a method for varying a pressure in a master cylinder (9) at the output of a gear comprising an internal sun gear (1) at the input of the gear driven by a motor (5) and a set of 'at least two planet wheels (2) attached to a planet carrier (3) forming an output of the planetary type gear and an outer planet gear (4). A friction is exerted on the outer planetary gear (4) regulated according to a pressure at the output of the gear representative of the torque delivered by the planetary type gear, a variation in friction causing a variation in torque at the output of the gear of planetary type, the friction exerted decreasing with an increase in the pressure at the output of the planetary type gear.
