Abstract

"APARELHO DE DIREçãO DE VEìCULO PARA GIRAR RODAS DIRIGìVEIS DE UM VEìCULO". Um aparelho de direção de veículo (10) para girar rodas dirigíveis (44) de um veículo compreende uma peça de entrada manualmente rotativa (12) à qual o torque de direção é aplicado, uma peça de saída (34) rotativa para efetuar o giro das rodas dirigíveis (44) do veículo, e um motor elétrico (102) para fornecer uma força de acionamento para girar a peça de saída (34) em função do torque de direção aplicado à peça de entrada (12). O motor elétrico (102) inclui um eixo de motor (100) que possui um eixo geométrico de rotação (104). Primeira e segunda marchas de engrenamento (54 e 56) transmitem a força de acionamento do motor elétrico (102) à peça de saída (34). A primeira marcha (54) é rotativa com a peça de saída (34), e a segunda marcha (56) é rotativa com o eixo de motor (100). Um mecanismo de ajuste (86, 122) ajusta o recuo entre a primeira e a segunda marchas (54 e 56). O mecanismo de ajuste (86, 122) inclui um mecanismo de montagem (70, 108) para montar ajustavelmente o motor elétrico (102) e a segunda marcha (56) em relação à primeira marcha (54). O mecanismo de montagem (70, 108) inclui superfícies excêntricas (80, 120) para deslocar o eixo geométrico de rotação (104) do eixo de motor (100) e a segunda marcha (56) em relação à primeira marcha (54).
