Abstract

SISTEMA DE DIREÇÃO ELETROMECÂNICA DUPLA PARA UM VEÍCULO UTILITÁRIO. A presente invenção refere-se a um sistema de direção eletromecânica dupla para um veículo utilitário, com duas direções (1a, b) compreendendo respectivamente uma unidade de acionamento (4), para o acionamento de um respectivo sistema de alavancas de direção (5a, b) para rodas (6a, b, c, d) do veículo utilitário, sendo que, cada unidade de acionamento (4) apresenta um respectivo motor elétrico (7) sendo que, o sistema de direção dupla tem uma alimentação principal (8) para a alimentação dos motores elétricos (7) com energia. O sistema de direção eletromecânica dupla é caracterizado pelo fato de que a sistema de direção dupla apresenta pelo menos uma alimentação de emergência (9) para a alimentação com energia de pelo menos um motor elétrico (7), no caso de uma falha da alimentação principal (8).
