Abstract

DISPOSICION DE SERVODIRECCION HIDROSTATICA. DOS RUEDAS ORIENTABLES (30, 31) ESTAN ACOPLADAS POR UN ENLACE DE VARILLAS (26) Y SON HECHAS FUNCIONAR POR ACTUADORES HIDRAULICOS (12 Y 13) CON CAMARAS DE CABEZA CONECTADAS A UNA VALVULA DE CONTROL DIRECCIONAL (38) QUE CONTROLA EL SUMINISTRO DE FLUIDO HIDRAULICO DESDE UNA BOMBA (34). LA VALVULA (38) ES SITUADA EN POSICION DE ACUERDO CON LA DIFERENCIA DE PRESION ENTRE CONDUCCIONES DE CONTROL (48, 49) CONECTADAS A UNA BOMBA DE DOSIFICACION (50) DE FUNCIONAMIENTO MANUAL. UNAS CAMARAS DE REALIMENTACION EN LOS LADOS DE LOS EMBOLOS (14, 15) CORRESPONDIENTES A LOS VASTAGOS EN LOS ACTUADORES (12, 13) ESTAN CONECTADAS A LAS CONDUCCIONES DE CONTROL (48, 49) QUE LO ESTAN A SU VEZ MEDIANTE UNA VALVULA DE COMPENSACION (54).
