Abstract

L'invention concerne un système de direction assistée pour véhicule automobile, comprenant une pompe (1) d'alimentation en fluide hydraulique sous pression, un réservoir de fluide hydraulique (5) à basse pression, un vérin hydraulique (3) d'assistance à la direction pour l actionnement d'un train de direction du véhicule et alimenté en fluide hydraulique sous pression par la pompe (1), par l'intermédiaire d'une valve de distribution (4), reliée à la colonne de direction (7) et au pignon (12) d'engrénement de la crémaillère de direction (13), solidaire en translation du piston du vérin, et des moyens anti-vibrations adaptés pour au moins atténuer la transmission de vibrations et de bruits au volant d'actionnement (10) de la colonne de direction. Le système est caractérisé en ce que les moyens anti-vibrations (22) sont réalisés par un dispositif de restriction de la section d'écoulement du fluide hydraulique, qui est monté dans le circuit basse pression reliant la sortie basse pression (24) de la valve (4) au réservoir (5). L'invention est utilisable dans des véhicules automobiles.
