Abstract

LA INVENCION SE REFIERE A UN SERVOMOTOR NEUMATICO DE ASISTENCIA A LA FRENADA, QUE LLEVA UNA ENVOLTURA (10) QUE POSEE UN EJE DE SIMETRIA (X-X''), SEPARADA DE MANERA ESTANCA POR UNA ESTRUCTURA DE PARED MOVIL (12) EN UNA CAMARA DELANTERA (14) CONECTADA PERMANENTEMENTE A UNA FUENTE DE BAJA PRESION, Y UNA CAMARA TRASERA (16) CONECTADA SELECTIVAMENTE A LA CAMARA DELANTERA (14) O A UNA FUENTE DE ALTA PRESION POR UNA VALVULA DE TRES VIAS (36) ACCIONADA POR UNA VARILLA DE CONTROL (28) QUE PENETRA, POR LA CARA FRONTAL DE UN BUZO (26), CON LA CARA TRASERA DE UNA VARILLA DE EMPUJE (82) SOLIDARIA A UNA PLACA DE REACCION (80). UN ALOJAMIENTO AUXILIAR (32) SOLIDARIO A DICHA PARED MOVIL (12) SE PROYECTA DENTRO DE LA CAMARA DELANTERA (14). UN PISTON AUXILIAR (34) DIVIDE DE MANERA ESTANCA EL INTERIOR DEL ALOJAMIENTO AUXILIAR INTERNO (32) EN UN VOLUMEN DELANTERO (36) Y UN VOLUMEN TRASERO (38, ESTANDO EL PISTON AUXILIAR (34) MONTADO FIJAMENTE RESPECTO A LA ENVOLTURA (10), ESTANDO EL VOLUMEN DELANTERO (36) PERMANENTEMENTE CONECTADO A LA CAMARA TRASERA (16) Y ESTANDO EL VOLUMEN TRASERO (38) PERMANENTEMENTE CONECTADO A LA CAMARA DELANTERA (14). DE ACUERDO CON LA INVENCION, EL SERVOMOTOR LLEVA ADEMAS AL MENOS UN ELEMENTO SOLIDARIO A LAS PAREDES DELANTERA (42) Y TRASERA (44) DE LA ENVOLTURA (10) PARA TRANSMITIR LA FUERZA DE REACCION (50, 100) QUE PASA A TRAVES DE LA ENVOLTURA AL EJE DE SIMETRIA (X-X'') DE DICHO SERVOMOTOR.
