Abstract

LA INVENCION SE REFIERE A UN MANDO HIDRAULICO DE, POR EJEMPLO, UNA EXCAVADORA SOBRE NEUMATICOS, QUE CONSTA DE DOS MOTORES (4, 6) QUE SE CONECTAN AL LADO DE ENTRADA DE UNA CAJA DE CAMBIO (8), POR MEDIO DE LA CUAL CADA MOTOR (4, 6) PUEDE APLICAR UNA FUERZA DE IMPULSION A UNA CARGA CONECTADA AL LADO DE SALIDA DE LA CAJA DE CAMBIO (8); UNO DE LOS MOTORES (6) SE PUEDE DESCONECTAR, DE MODO SELECTIVO, DEL OTRO MOTOR (4) POR MEDIO DE UN EMBRAGUE (10). UN SISTEMA DE CONTROL PARA EFECTUAR LA REFERIDA DESCONEXION COMPRENDE: UNA BOMBA HIDRAULICA (20) IMPULSADA POR LA CAJA DE CAMBIO (8) PARA QUE GIRE A UNA VELOCIDAD PROPORCIONAL A LA DEL OTRO MOTOR (4), UN SENSOR DE PRESIONES (24) PARA DETECTAR LA PRESION DEL FLUIDO DESPLAZADO POR LA BOMBA (20) Y UNOS CONTROLES (28) PARA LOGRAR LA ACTUACION SELECTIVA DEL EMBRAGUE (10), DE MODO QUE, CUANDO EL SENSOR (24) DETECTE LA PRESION ASOCIADA CON UNA VELOCIDAD PREFIJADA DEL OTRO MOTOR (4), A LA QUE LA IMPULSION DEL PRIMER MOTOR (6) RESULTA SUPERFLUA, LOS CONTROLES(28) FUNCIONAN Y DESCONECTAN EL PRIMER MOTOR DE LA CAJA DE CAMBIO (8).
