Abstract

SENSOR DE PRESION PARA NEUMATICO DE VEHICULOS AUTOMOVILES, QUE COMPRENDE UNA CAMARA DE PRESION (20) CON UNA ESPIGA DE CONTACTO (22), QUE COOPERA CON UNA MEMBRANA (21) CONDUCTORA DE LA ELECTRICIDAD, QUE CIERRA LA CAMARA DE PRESION DE REFERENCIA (20) HACIA EL NEUMATICO. PARA ELEVAR EL UMBRAL DE CONEXION, EN FUNCION DE LA VELOCIDAD, SE HA FIJADO LIBREMENTE UNA MASA ADICIONAL (30) SOBRE EL CENTRO DE LA MEMBRANA Y SE HA DIMENSIONADO DE TAL FORMA QUE CON RADIO R PREFIJADO DE LA MEMBRANA (21), UN RADIO R DE ROTACION PREFIJADO DE LA MEMBRANA (21) Y UNA VELOCIDAD PREFIJADA DE ROTACION Y DE LA MEMBRANA (21) SE ELEVA EL UMBRAL DE CONEXION EN UNA DIFERENCIA DE PRESION DESEADA (QP) CON RESPECTO AL UMBRAL DE CONEXION PSIO EN REPOSO. LA MASA ADICIONAL NECESARIA (M) SE DEDUCE DE LA RELACION M = F (QP, V, R, R).
