Abstract

Sistema de asistencia de freno que comprende un muelle intermedio (8) que se combina con un tope de presión (81) que limita la compresión a una fuerza que es mayor que la fuerza contraria del pedal de freno en condiciones de funcionamiento normales. El muelle (8) y su tope (81) se colocan entre el émbolo buzo (2) y el émbolo de asistencia (5), para que el muelle (8) transmita el empuje del émbolo de asistencia (5) al émbolo buzo (2), el cual en condiciones de frenado normales jala el pedal de freno. El émbolo de asistencia (5) empuja al émbolo buzo (2) con el tope de presión (81) cuando la fuerza contraria del émbolo buzo (2) excede el valor umbral de presión. Un detector de contacto (9) detecta el contacto entre el émbolo de asistencia y el tope (5).
