Abstract

1. Dispositivo de mando de frenos de vehículo, particularmente de mando hidráulico de los frenos de fricción de un vehículo automóvil, del tipo que comprende, por una parte, un primer cilindro principal cuyo pistón está mandado por presión del pie del conductor sobre un pedal de freno y, por otra parte, un segundo cilindro principal independiente del primero y cuyo pistón está mandado por un medio distinto que dicha presión sobre un pedal de freno, preferentemente por soltado del pedal del acelerador, estando la salida del primer cilindro principal directamente conectada al circuito de mando hidráulico de los frenos de fricción y estando el conducto de salida del segundo cilindro principal exclusivamente conectado al primer cilindro principal, dispositivo para el cual además, por una parte, el medio distinto que la presión sobre el pedal de freno es disparable por la iniciativa del conductor en el curso de la marcha del vehículo, repetitivo, y dispuesto de manera que no engendre más que una presión hidráulica de frenado relativamente suave y, por otra parte, el conducto de salida del segundo cilindro principal está conectado al primer cilindro principal en el emplazamiento habitualmente utilizado para conectar este último a un depósito de líquido que lo alimenta, estando entonces este depósito reemplazado por este conducto de salida, caracterizado porque el primer cilindro principal es un cilindro principal tándem (26) que comprende un primer pistón (31) conectado por medio de un tirante (4) al pedal de freno y un segundo pistón (32) que divide la cavidad cilíndrica interior de este cilindro principal tándem en dos cámaras, a saber: una primera cámara (27) situada entre los dos pistones y conectada por un primer conducto de salida (61) a un primer circuito de mando hidráulico de frenado y una segunda cámara (28) situada en el extremo del cilindro y conectada por un segundo conducto de salida (62) a un segundo circuito de mando hidráulico de frenado, estando estas dos cámaras alimentadas con líquido a través, respectivamente, de dos toberas laterales (21, 22) y porque el conducto de salida (14) del segundo cilindro principal está conectado a una de estas dos toberas laterales en lugar de depósito habitual.
