Abstract

L'invention concerne une direction assistée électrique pouvant supprimer les vibrations, lesquelles peuvent sinon être transmises depuis un moteur électrique jusqu'à une unité ECU, tout à fait régulière dans le cas où l'unité ECU et le moteur électrique sont disposés à côté l'un de l'autre. Dans un réducteur (4) est montée une unité de commande (19) qui inclut une carte de commande (25), une carte d'un module de puissance (23) et un carter de protection (26). La carte du module de puissance (23) est montée directement sur une face de montage (20a) de l'unité de commande du réducteur, et les bornes de connexion d'un moteur électrique (5) sont reliées directement à l'unité de commande (19). Sur le profil de surface maximale du carter de protection (26), en outre, est monté un élément de prévention contre les vibrations (26a), qui agit comme mécanisme de prévention contre les vibrations afin d'empêcher l'unité de commande (19) de résonner avec les vibrations provenant du moteur électrique (5).
