Abstract

SE PRESENTA UN SISTEMA DE FRENO DE ESTACIONAMIENTO QUE INCLUYE UNA VALVULA ACCIONADA POR SOLENOIDE DOBLE (20) COLOCADA EN SERIE RESPECTO A LA VALVULA DE CONTROL DEL FRENO DE EMERGENCIA (18) DE UN SISTEMA DE FRENO HIDRAULICAMENTE ACCIONADO. LA VALVULA DE SOLENOIDE DOBLE SE PUEDE ACCIONAR PARA QUE PASE A UNA DE DOS POSICIONES DE RETENCION MECANICAS (38) DE AL MODO QUE EL POSICIONAMIENTO DE LA VALVULA QUEDE RETENIDO EN CASO DE UNA PERDIDA DE ENERGIA. EL OPERADOR DEL VEHICULO ES EL QUE CONTROLA LA VALVULA DE SOLENOIDE DOBLE DESDE LA CONSOLA DE TRANSMISION (40) Y ELIMINA LA PRESION HIDRAULICA DE LOS FRENOS CUANDO SE ACCIONAN A UNA POSICION DE ESTACIONAMIENTO. HAY UNA UNIDAD DE CONTROL ELECTRONICA (46) PARA DETECTAR LA VELOCIDAD DEL VEHICULO Y LA PRESION DE LA LINEA HIDRAULICA A LOS FRENOS Y GENERA UNA SEÑAL DE PERMISO DE ESTACIONAMIENTO CUANDO LA VELOCIDAD DEL VEHICULO ES MENOR A UNA CANTIDAD PREDETERMINADA. CUANDO SE SELECCIONA UNA MARCHA EN LA CONSOLA, LA VALVULA DE SOLENOIDE DOBLE SE ACCIONAA UNA POSICION QUE PERMITE QUE LA PRESION HIDRAULICA SEA APLICADA A LOS FRENOS Y DEVUELVE DE FORMA EFECTIVA EL CONTROL DE LOS FRENOS AL DISPOSITIVO DE CONTROL DE LOS FRENOS DE EMERGENCIA. EN LA LINEA (16) A LOS FRENOS HAY UN DETECTOR DE LA PRESION (48) Y SE UTILIZAR PARA PROPORCIONAR UNA REALIMENTACION AL CONDUCTOR Y PARA CONTROLAR EL CAMBIO DE TRANSMISION.
