Abstract

LA INVENCION SE REFIERE A UN SERVOFRENO ACCIONADO POR VACIO QUE PRESENTA UN ELEMENTO DE ENTRADA (32) AL QUE LLEGA UNA FUERZA DE ACTIVACION Y UN ELEMENTO DE SALIDA (42) QUE SUMINISTRA UNA FUERZA AMPLIADA A UNA UNIDAD, TAL COMO UN CILINDRO PRINCIPAL (12), CONECTADA A CONTINUACION. DADO QUE CADA COMPONENTE DE LA UNIDAD DE SERVOFRENO (10) PRESENTA UN CIERTO GRADO DE TOLERANCIA, A LO LARGO DEL TRAYECTO DE ACTIVACION SE PRODUCEN INEVITABLEMENTE HOLGURAS LONGITUDINALES QUE TIENEN UN EFECTO INDESEADO SOBRE LAS CARACTERISTICAS DEL SISTEMA DE SERVOFRENO Y QUE DEBEN SER CONVENIENTEMENTE ELIMINADAS O AL MENOS REDUCIDAS. PARA EVITAR TENER QUE MANTENER PREPARADAS UNA SERIE DE ARANDELAS DE CONTACTO (36) Y ARANDELAS DISTANCIADORAS (62) DE DIFERENTES GROSORES PARA EQUILIBRAR LA LONGITUD, LA INVENCION PROPONE CALIBRAR LA LONGITUD DEL ELEMENTO DE ENTRADA (32) Y/O DEL ELEMENTO DE SALIDA (42) MEDIANTE CONFORMACION A PRESION A UNA LONGITUD TEORICA CALCULADA COMPARANDO UN VALOR REAL CON UN VALOR DE REFERENCIA ANTES DE SER MONTADA EN LA UNIDAD DE SERVOFRENO (10).
