Abstract

PARA LA ACTIVACION DE MECANISMOS DE RETROTENSADO O DE SISTEMAS DE RETENCION CON COJIN DE AIRE EN VEHICULOS SIRVE UNA MASA (22) DE INERCIA SENSIBLE AL VEHICULO MONTADA DE FORMA GIRATORIA EN UNA CARCASA (10). UNA PIEZA (18) DE PERCUSION, MONTADA DE FORMA GIRATORIA EN LA CARCASA (10) Y SOMETIDA A LA ACCION DE UN RESORTE EN LA DIRECCION DE UN PERCUTOR (30), APOYA, A TRAVES DE UNA POLEA (24), MONTADA EN ELLA CON GIRO SUAVE, EN UNA SUPERFICIE (26) CURVA DE LA MASA (12) DE INERCIA. LA FORMA DE LA SUPERFICIE (26) CURVA, LA TRAYECTORIA DE LA POLEA (24) DURANTE UN MOVIMIENTO DE GIRO DEL PERCUTOR (18) SOMETIDO A LA ACCION DE Y UN RESORTE Y EL SENTIDO DEL MOVIMIENTO DE LA MASA (12) DE INERCIA SE COMPAGINAN DE TAL MODO ENTRE SI, QUE SE SIMULEN LOS CRITERIOS DE ACTIVACION DE UN CIRCUITO ELECTRONICO DE ACTIVACION, QUE, POR ENCIMA DE UN DETERMINADO UMBRAL, INTEGRA LOS VALORES DE RETARDO CON RELACION AL TIEMPO. CON LA UTILIZACION DE RODAMIENTOS Y CON EL CIERRE HERMETICO DE LA CARCASA PERMANECEN INVARIABLESDURANTE MUCHO TIEMPO LOS PARAMETROS DE ACTIVACION.-
