Abstract

L'invention concerne un amortisseur électromagnétique utilisant un moteur électrique amélioré utilisant un engrenage planétaire, comprenant un amortisseur hydraulique à ressort reliant une carrosserie de véhicule (10) à des roues (11), un engrenage amortisseur (14) situé sur un essieu (12) de la roue (11), une crémaillère d'engrenage (13) s'engrenant avec l'engrenage amortisseur (14) pour la transmission et reliée de manière fixe sur la carrosserie de véhicule, et un moteur électrique amélioré utilisant un engrenage planétaire pour entraîner l'engrenage amortisseur (14) en rotation. La présente invention utilise le moteur électrique amélioré utilisant un engrenage planétaire pour entraîner l'engrenage amortisseur à s'engrener avec la crémaillère d'engrenage pour la transmission et pour générer une contre-force opposée à celle des roues de façon à contrebalancer la vibration des roues. L'invention présente une vitesse de réponse rapide et un effet d'amortissement favorable.
