Abstract

EL IMPULSOR DE FRENO HIDRAULICO (12) DEL PRESENTE INVENTO COMPRENDE UN IMPULSOR DE FRENO HIDRAULICO A TODA POTENCIA (12) QUE EFECTUA UN RECORRIDO FALSO DURANTE LA OPERACION A TODA POTENCIA E INDICADOR DE PEDAL MEJORADO DURANTE LA OPERACION MANUAL. EL IMPULSOR (10) POSEE UNA CAJA (24) CON UN CONJUNTO DE MANGUITO DESLIZABLE (60) EN SU INTERIOR, ALBERGANDO EL CONJUNTO (60) UN ELEMENTO DE MANGUITO (98) QUE ES DESPLAZADO POR PRESION DE FLUIDO ACUMULADOR CONTRA UNA CAJA DE ANILLO DE GUIA (78) UN ELEMENTO DE ANILLO DE GUIA MOVIL (79) LOCALIZADO ALREDEDOR DE UN ELEMENTO DE ENTRADA (94). EL ELEMENTO DE MANGUITO (98) DESPLAZA EL ELEMENTO DE ANILLO DE GUIA MOVIL (79) CONTRA UN ELEMENTO ELASTICO (77) CUANDO EL ELEMENTO DE MANGUITO (8) SE DESPLAZA POR PRESION DE FLUIDO HIDRAULICO DESDE EL ACUMULADOR (14), EN AUSENCIA DE PRESION DEL FLUIDO HIDRAULICO, EL ELEMENTO DE MUELLE (77) DESPLAZA EL ELEMENTO DE ANILLO DE GUIA MOVIL (79) CONTRA EL ELEMENTO DE MANGUITO (98) DE MODO QUE EL ELEMENTO DE ANILLO DE GUIAMOVIL (79) ESTE ATRAPADO FIJAMENTE ENTRE LA CAJA DE ANILLO DE GUIA (78) Y EL ELEMENTO DE ENTRADA (94) PARA ACOPLAR EL ELEMENTO DE ENTRADA (94) CON EL ELEMENTO DE MANGUITO (60) PARA MOVIMIENTO CONJUNTO EN EL ORIFICIO DE ACOGIDA DE IMPULSOR (26).
