Abstract

DISPOSITIVO CONTROLADOR DE FRICCION, CAPAZ DE REDUCIR LAS FUERZAS DE FRICCION POR APLICACION DE VIBRACION ULTRASONICA. CONSTA DE UN MIEMBRO MOVIL O DISCO (1) UNIDO A LA RUEDA; UN MIEMBRO DE FRICCION O ZAPATA DE FRENO (2); UN SENSOR (3) MONITOR DE LA VELOCIDAD ANGULAR DE LA RUEDA; UN GENERADOR ULTRASONICO (4) Y UN TTRANSDUCTOR MAGNETO-ESTRICTIVO (8). DURANTE LA APLICACION DEL FRENADO, CUANDO EL SENSOR TRANSMITE UNA SEÑAL AL GENERADOR ULTRASONICO, ESTE ENVIA ENERGIA A LA BOBINA (7), EXCITANDOSE COMO CONSECUENCIA EL TRANSDUCTOR MAGNETO-ESTRICTIVO. DE ESTE MODO SE APLICA UNA VIBRACION ULTRASONICA A LA ZAPATA DE FRENO, REDUCIENDOSE LA FUERZA DE FRICCION ENTRE LA ZAPATA Y EL DISCO, CON LO QUE LA RUEDA RECUPERA VELOCIDAD. EN ESTE PUNTO EL SENSOR DEJA DE APLICAR LA SEÑAL AL GENERADOR ULTRASONICO Y ES REAPLICADA LA FUERZA NORMAL DE FRENADO. ESTA SECUENCIA DE OPERACIONES ES REPETITIVA MIENTRAS LA RUEDA TENGA TENDENCIA A BLOQUEARSE. ESTE DISPOSITIVO ANTI-BLOQUEO SE USA EN LOS SISTEMAS DE FRENADO DE VEHICULOS CON FRENOS HIDRAULICOS O NEUMATICOS. C
