Abstract

UN SERVOFRENO QUE TIENE UN PISTON ACTUADO POR FLUIDO EN FORMA DE DIAFRAGMA (5) EN EL QUE EL SUMINISTRO DE FLUIDO SE CONTROLA MEDIANTE UN MECANISMO DE VALVULA (8A,14A,17), ACTIVADO POR UN ELEMENTO DE ENTRADA DE FUERZA CONDUCTOR-OPERADO QUE ACTUA A TRAVES DE UN ELEMENTO DE REACCION (19) EN UN ELEMENTO DE SALIDA (10), PROPORCIONANDO UNA ENTRADA ASISTIDA A UN CILINDRO PRINCIPAL. EL SERVOFRENO INCLUYE UN ENSAMBLAJE DE TRANSMISION DE FUERZA (14,8) QUE PROPORCIONA SUPERFICIES A TRAVES DE LAS CUALES SE TRANSMITE LA FUERZA ENTRE LOS ELEMENTOS DE ENTRADA Y SALIDA (16,10). EL MECANISMO QUE CEDE (24) ESTA DISPUESTO PARA CEDER BAJO UNA FUERZA PREDETERMINADA Y PERMITIR UN MOVIMIENTO RELATIVO ENTRE LAS PARTES (14 Y 8), PARA CAMBIAR EL INDICE DE LAS AREAS DE SUPERFICIES OPERATIVA Y ASI INCREMENTAR EL INDICE DEL SERVOFRENO.
