Abstract

Se proporciona una zapata de freno (48, 50) para un freno de tambor (40) que mejora la dirección de las fuerzas de accionamiento del freno para reducir la tensión, mejorar la eficiencia y permitir forros de freno más gruesos. La zapata de freno (48, 50) tiene una banda (68) que tiene primero (74) y segundo (78) extremos con el primer extremo (74) configurado para acoplarse de forma pivotante a una cruceta de freno asociada (44). Una mesa de freno está soportada en la banda. El segundo extremo (78) de la banda está configurado para acoplar un seguidor de leva asociado (58, 60) que hace que la zapata de freno (48, 50) se mueva entre posiciones de acoplamiento y desacoplamiento con una superficie de frenado asociada en cualquiera de primera y segunda posiciones radialmente desplazadas en el segundo extremo de la banda, de tal modo que los seguidores de leva puedan acoplar dos zapatas de freno (48, 50) en el freno en posiciones desplazadas y mejoren la dirección de los vectores de fuerza.
