Abstract

Patente de Invenção "CONJUNTO DE SERVO-DIREçãO COM CENTRO ABERTO, E, PROCESSO PARA O CONTROLE DE UM MOTOR ELéTRICO DE ACIONAMENTO DA BOMBA DE UM CONJUNTO DE SERVO-DIREçãO''. A invenção se refere a um conjunto de servo-direção com uma servo-válvula (6) com centro aberto, para fornecimento de pressão hidráulica a um órgão e controle (1) e com uma bomba (7), acionável por um motor elétrico (13) para alimentação da servo-válvula (6) com fluido hidráulico, em que a entrada de potência do motor elétrico (13), através de uma unidade eletrónica (21), é controlável em resultado da comparação de parâmetros operacionais, controlados ou vigiados por meio de sensores, com valores, teóricos prefixados, em que se propõe a ligação dos sensores com uma unidade de controle que apresenta pelo menos um microporcessador que determina valores teóricos ou de referência na dependência de parâmetros operacionais controlados ou vigiados.
