Abstract

EL INVENTO SE REFIERE A UN SISTEMA DE FRENADO HIDRAULICO ASISTIDO QUE CONSTA DE: UN PEDAL DE FRENO (10) ENLAZADO A UNA VARILLA DE ACCIONAMIENTO (46); UN SERVOMOTOR NEUMATICO (14) QUE CONSTA DE UNA CAMARA DE DEPRESION DELANTERA (102) Y UNA CAMARA DE TRABAJO POSTERIOR (104) SEPARADAS POR UN TABIQUE ESTANCO MOVIL, SOLIDARIO DE LA VARILLA DE EMPUJE; UN CILINDRO-MAESTRO SENCILLO (16) CUYO PISTON ES ACCIONADO POR LA VARILLA DE EMPUJE; UNOS ELEMENTOS (12) DE CONTROL DEL SERVOMOTOR (14) QUE CONSTAN DE UN ELEMENTO DE VALVULA (34) QUE PONE EN COMUNICACION, DE FORMA SELECTIVA, UNA PRIMERA CAMARA (26) CON UNA SEGUNDA CAMARA (30) O CON LA ATMOSFERA, EN RESPUESTA AL ACCIONAMIENTO DEL PEDAL DE FRENO (10); UNA PRIMERA CANALIZACION (10) QUE HACE QUE SE COMUNIQUE LA PRIMERA CAMARA (26) DE LOS ELEMENTOS DE CONTROL (12) CON LA CAMARA DE TRABAJO (104) DEL SERVOMOTOR (14); UNA SEGUNDA CANALIZACION (112) QUE HACE QUE SE COMUNICA LA SEGUNDA CAMARA (30) DE LOS ELEMENTOS DE CONTROL (12) CON LA CAMARA DE DEPRESION (102) DEL SERVOMOTOR (14); UN SEGUNDO CILINDRO-MAESTRO (74) CUYAS SALIDAS ESTAN ENLAZADAS CON AL MENOS UN FRENO DE RUEDA. SEGUN EL INVENTO, EL SEGUNDO CILINDRO-MAESTRO (74) SE SOMETE A LA PRESION TRANSMITIDA POR LA VARILLA DE ACCIONAMIENTO (46) AUMENTADA DE LA PRESION DE ASISTENCIA CREADA POR EL CILINDRO-MAESTRO SENCILLO (16).
