Abstract

"SISTEMA DE DIREçãO HIDRáULICA AUTOMOTIVA DE ALTA EFICIêNCIA". é descrito um sistema de direção com energia hidráulica para uso em um veículo para eliminar desperdício de energia quando nenhuma ajuda de energia é requerida. O sistema de direção com energia hidráulica (10, 20) inclui uma polia (12) energizada por um eixo de manivela no veículo, uma embreagem (16) operavelmente conectada à polia, uma bomba hidráulica (14) operavelmente conectada à embreagem, e dispositivos de controle (18, 34, 36) para engatar e desengatar a embreagem (16) com a polia (12) e a bomba hidráulica (14) para fornecer energia hidráulica ao sistema. Ele também inclui um acumulador hidráulico (22) para fornecer pressão de sistema por períodos curtos antes da embreagem da bomba poder engatar em resposta a uma entrada de direção.
