Abstract

Frein à disque électromécanique comportant un étrier (102), des plaquettes de frein (P1, P2), un piston (111) monté mobile en translation dans l’étrier (102) le long d’un axe longitudinal (X), et un actionneur électromécanique (108) configuré pour déplacer le piston (111) contre la plaquette de frein (P1) et l’appliquer contre un disque de frein, ledit actionneur électromécanique (108) comportant un moteur électrique (M), un système de réduction (R), un système vis-écrou pour déplacer en translation au piston (111), dans lequel le système de réduction (R) comporte un porte-satellite (2) portant des satellites (4), un planétaire (1) mis en rotation par le moteur électrique, une couronne (6) fixe munie d’une denture intérieure (16), et dans lequel lesdits satellites (4) sont des satellites doubles comportant un premier pignon (4.1) engrenant le planétaire (1) et un deuxième pignon (4.2) engrenant la denture intérieure (16) de la couronne (6), lesdits premier (4.1) et deuxième (4.2) pignons étant solidaires en rotation l’un de l’autre.
