Abstract

Bloc hydraulique de servofrein électromécanique comprenant un module hydraulique (200) entraîné par un moteur électrique pour alimenter le circuit de freinage et ayant un cylindre (1, 2) recevant un piston (3) guidé en translation et bloqué en rotation pour comprimer le liquide de frein dans la chambre (11) et une transmission à vis (4) entraînée par le moteur électrique et activant le piston (3). Le cylindre (1, 2) est formé d'une tête (1) délimitant la chambre (11) et, d'un manchon de guidage (2) solidarisé à la tête (1) et dont la surface intérieure a de rainures de guidage (21) parallèles à l'axe (XX) du cylindre. Le piston (3) est muni près de son extrémité ouverte, opposée au fond (32), d'une couronne dentée (31) de forme homologue à celle des rainures (21) du manchon (2) pour être guidé en translation et bloqué en rotation.
