Abstract

UN DISPOSITIVO CORRECTOR DE FRENADO PARA UN VEHICULO AUTOMOVIL PROVISTO DE UN SISTEMA DE FRENOS HIDRAULICO Y UN SISTEMA DE NIVELACION AUTOMATICA CON MUELLES NEUMATICOS INCLUYE UN DISPOSITIVO DE ACCIONAMIENTO QUE DEFINE DOS CAMARAS QUE ESTAN AMBAS DIVIDIDAS EN ESPACIOS PRIMERO Y SEGUNDO POR RESPECTIVOS DIAFRAGMAS. LOS PRIMEROS ESPACIOS DE LAS CAMARAS COMUNICAN CON RESPECTIVOS MUELLES NEUMATICOS Y LOS SEGUNDOS ESPACIOS COMUNICAN CON LA ATMOSFERA A TRAVES DE ESTRECHOS PASOS CUYAS DIMENSIONES ESTAN CALIBRADAS DE MANERA QUE SE LIMITA LA PERDIDA DE AIRE A LA ATMOSFERA EN EL CASO DE LA ROTURA DE UNO DE LOS DIAFRAGMAS. LA PERDIDA DE AIRE ORIGINA UNA VARIACION DEL COMPORTAMIENTO DEL VEHICULO Y ELLO DA LUGAR A LA ACTIVACION DEL COMPRESOR DEL SISTEMA DE NIVELACION, DE MANERA QUE SE COMPENSA LA PERDIDA.
