Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE FRENADO ASISTIDO PARA VEHICULO DE MOTOR, QUE COMPRENDE UN CILINDRO PRINCIPAL (200) Y UN SERVOMOTOR NEUMATICO DE ASISTENCIA (100) SUSCEPTIBLE DE SER CONTROLADO POR LA APLICACION DE UNA FUERZA DE ENTRADA EN UNA VARILLA DE MANDO (26). EL SERVOMOTOR TIENE UNA CARCASA RIGIDA (10) DIVIDIDA DE MANERA ESTANCA EN AL MENOS DOS CAMARAS (12, 14) MEDIANTE AL MENOS UN TABIQUE MOVIL (16), SUSCEPTIBLE DE SER SOLICITADO POR UNA DIFERENCIA DE PRESION ENTRE LAS DOS CAMARAS (12, 14) QUE RESULTA DE LA APERTURA DE UNA VALVULA DE TRES VIAS (24). EL PISTON HIDRAULICO PRINCIPAL (30) DEL CILINDRO PRINCIPAL (200) TIENE, A SU VEZ, UN CILINDRO MOVIL (32) HUECO, QUE COMUNICA CON EL VOLUMEN INTERIOR (V) DEL CILINDRO PRINCIPAL Y EN EL INTERIOR DEL CUAL SE DESLIZA, DE MANERA ESTANCA, UN PISTON HIDRAULICO SECUNDARIO (34). EL PISTON HIDRAULICO SECUNDARIO (34) TIENE UNA VALVULA DE DOS VIAS (56) NORMALMENTE ABIERTA, SUSCEPTIBLE DE INTERRUMPIR LA COMUNICACION ENTRE EL VOLUMEN INTERIOR(V() DEL CILINDRO PRINCIPAL Y EL INTERIOR (35) DEL CILINDRO MOVIL CUANDO LA VARIACION DE LA FUERZA DE ENTRADA ES SUPERIOR A UN VALOR PREDETERMINADO. SEGUN LA INVENCION, EL PISTON HIDRAULICO SECUNDARIO (34) ES COMPUESTO, Y TIENE UNA SEGUNDA PARTE (50) TOPANDO, EN POSICION DE REPOSO, CONTRA EL CILINDRO MOVIL (32) BAJO EL EFECTO DE LOS PRIMEROS MEDIOS ELASTICOS (46) Y UNA SEGUNDA PARTE (52) SUSCEPTIBLE DE DESLIZARSE RESPECTO A LA PRIMERA PARTE (50), SEGUNDOS MEDIOS ELASTICOS (54, 92) QUE EJERCEN HACIA LA PARTE POSTERIOR UNA SEGUNDA FUERZA ELASTICA SOBRE LA SEGUNDA PARTE (52) PARA SOLICITARLA Y HACERLA CHOCAR EN POSICION DE REPOSO CONTRA LA PRIMERA PARTE (50).
