Abstract

Dispositivo de frenado asistido, que comprende un pistón principal, montado deslizante en un cilindro principal, un gato axialmente alineado con el cilindro principal, y que tiene un pistón unido al pistón de mando por medios de interconexión axialmente alineados, medios de empuje adaptados para ser accionados por un pedal, una fuente de presión hidráulica de asistencia, un distribuidor adaptado para alimentar el gato en presión hidráulica de asistencia a partir de la citada fuente, medios de palanca adaptados para accionar el distribuidor en respuesta a un desplazamiento de los medios de empuje, y medios de tope de seguridad que son activados en caso de fallo de la presión hidráulica de asistencia, para permitir que el pistón de mando sea desplazado bajo el efecto directamente ejercido por los medios de empuje, caracterizado porque los citados medios de palanca llevan un brazo, uno de cuyos extremos actúa sobre el citado distribuidor, estando el citado brazo montado basculante, por una articulación, sobre los citados medios de interconexión.
