Abstract

Un sistema (20) de freno comprende: un cilindro (26) maestro y una bomba (12) para presionar selectivamente un cilindro o cilindros de freno asociados; un motor (14) para energizar la bomba; un circuito (16, 90) de control para modular la velocidad del motor en respuesta a una señal indicativa del esfuerzo de frenado deseado y el esfuerzo de frenado real, y una válvula (30) de control que responde a la presión del cilindro maestro para controlar el flujo de la bomba y para permitir la disminución de presión en los cilindros de freno.
