Abstract

CIRCUITO HIDRáULICO PARA UM SISTEMA DE DIREçãO DE COMANDO POR CABO. Diz respeito a um circuito hidráulico para um sistema de direção de comando por cabo que inclui uma bomba hidráulica, um reservatório, um atuador de direção bidirecional, um par de unidades de controle eletrónico (ECU) para gerar sinais elétricos de controle de direção em resposta a um comando de direção gerado pelo operador. Existe uma necessidade de um circuito como esse que não exija válvulas grandes e caras. O circuito hidráulico inclui um par de unidades de válvulas de controle direcional operadas por solenóide e um par de válvulas de fechamento operadas por solenóide. Cada unidade de válvula de controle direcional e uma válvula correspondente das válvulas de fechamento são conectadas em série entre a bomba, o reservatório e o atuador de direção, e são conectadas a uma respectiva das ECUs e controladas por ela. Na ausência de uma condição falha, ambas as válvulas de fechamento são abertas para que o fluxo hidráulico a favor e contra o amador seja compartilhado tanto pela primeira como pela segunda unidade de válvula de controle direcional.
