Abstract

L'invention concerne un dispositif de direction assistée électrique, ayant un bruit de fonctionnement réduit, obtenu à faible coût. Le dispositif de direction assistée électrique (1) est constituée d'une colonne de direction (2) recevant un arbre de direction (15) et d'un appareil électrique (35). Un matériau insonorisant est disposé sur la colonne de direction (2) et/ou l'appareil électrique (35). Le matériau insonorisant (55) est fixé par un élément de fixation (56) à un couvercle de boîtier d'engrenage (33) faisant partie de colonne de direction (2).
