Abstract
EMBOLO DE TRABAJO ESPECIALMENTE PARA UN AMPLIFICADOR DEL ESFUERZO DE FRENADO, QUE DEBE ADMITIR UN CONSIDERABLE NUMERO DE ALTERNANCIAS DE CARGA, EN LAS QUE ACTUAN GRANDES FUERZAS SOBRE DICHO EMBOLO. DEBIDO A LOS ELEVADOS ESFUERZOS QUE ACTUAN EN DIRECCION AXIAL, EL EMBOLO DEBE QUEDAR BIEN ASEGURADO SOBRE EL EJE DE GUIA. POR OTRA PARTE, EL TALON DE LA GUIA CENTRAL QUE MANTIENE AL EMBOLO EN DIRECCION AXIAL PUEDE LLEVAR A CARGAS LOCALES SOBRE EL MISMO Y, CON ELLO, A FATIGAS EN EL MATERIAL, QUE DETERMINEN UN FALLO PREMATURO DEL EMBOLO. ESTO SE CONSIGUE, EN PRINCIPIO, NO SUJETANDO FIRMEMENTE YA EL CONTORNO CENTRAL DEL EMBOLO SOBRE LA GUIA CENTRAL, SINO DANDO FORMA AL EXTREMO INTERIOR Y AL APOYO DE MANERA QUE SEA POSIBLE UN MOVIMIENTO BASCULANTE DEL PLATO DE EMBOLO SIN CARGAS LOCALES POR FLEXION, CON LO QUE SE PROLONGA NOTABLEMENTE LA VIA DE DICHO EMBOLO.
