Abstract

LOS SISTEMAS DE DIRECCION DE MODIFICACION DE RELACION VARIABLE DE TIPO PREVIO O BIEN SON DEMASIADO COMPLICADOS Y CON ELLO DEMASIADOS CAROS O FALLAN EN EL CUMPLIMIENTO DE LOS REQUERIMIENTOS DE SEGURIDAD RIGUROSOS. EL PRESENTE SISTEMA DE DIRECCION HIDRAULICA CAMBIA AUTOMATICAMENTE DE UNA A OTRA LAS RELACIONES DE DIRECCION Y DE FORMA MUY SEGURA SOBRE LA TRANSMISION A PARTIR DE LA OPERACION EN DISPOSICION DE SERVO O DE EMERGENCIA. EN EL SISTEMA DE EQUIPO DE DIRECCION, SOLO UNAS POCAS DE LAS LINEAS (13) ENLAZAN LA BOMBA (10) DOSIFICADORA A UNA DE LAS CONEXIONES (7,8) DE CILINDRO Y EN CADA UNA DE LAS OTRAS LINEAS (13'') SE DISPONE DE UNA UNIDAD (16) DE CONMUTACION QUE ENLAZA TAMBIEN LAS LINEAS (13) A LAS CONEXIONES (7,8) DE CILINDRO O A LA CONEXION (6) DE ENTREGA DEPENDIENDO DEL METODO DE OPERACION. ESTOS SISTEMAS DE EQUIPO DE DIRECCION HIDRAULICOS SON UTILIZADOS EN SISTEMAS MOVILES, EN PARTICULAR EN VEHICULOS DE CIRCULACION LENTA.
