Abstract

L'invention concerne une unité d'actionnement de frein (1, 1', 1") pour un système de freinage de véhicule automobile comprenant un amplificateur de force de freinage à dépression (2) et un groupe pompe-moteur (3) destiné à produire une dépression, comportant une pompe reliée à l'amplificateur de force de freinage à dépression (2) et un moteur électrique entraînant la pompe. Selon l'invention, l'unité d'actionnement de frein comporte un élément insonorisant supplémentaire (4, 4', 4'') dans la liaison entre l'amplificateur de force de freinage à dépression (2) et la pompe pour abaisser le niveau de pression sonore dans l'habitacle.
