Abstract

UN CONJUNTO (11) ACUMULADOR PARA UN SISTEMA DE FRENO ANTIBLOQUEO DE VEHICULOS RECIBE Y ALMACENA PROVISIONALMENTE FLUIDO DURANTE FASES DE REDUCCION DE PRESION DE LA OPERACION ANTIBLOQUEO Y MANTIENE EL FLUIDO ALMACENADO DENTRO, SUSTANCIALMENTE EN, O CERCA DE, PRESION CERO DURANTE LA OPERACION ANTIBLOQUEO. EL ACUMULADOR HABILITA LA PRESION DEL FLUIDO A LOS FRENOS CONTROLADOS (20A, 20B) PARA REDUCIRSE SUSTANCIALMENTE CERCA DE LA PRESION CERO. EL ACUMULADOR ESTA DESPUES OPERATIVO, DESPUES DE FRENAR EL VEHICULO, PARA APLICAR UNA PRESION PREDETERMINADA POR ENCIMA DE LA PRESION CERO AL FLUIDO DEL FRENO ALMACENADO DENTRO, FACULTANDO AL FLUIDO A QUE VUELVA AL SISTEMA DE FRENOS. EL ACUMULADOR SE UTILIZA VENTAJOSAMENTE EN UN SISTEMA ANTIBLOQUEO SIN BOMBA, QUE ESTA OPERATIVO PARA CONTROLAR LOS FRENOS DE DISCO POSTERIORES (20A, 20B) DE UNA CAMIONETA DE REPARTO.
