Abstract
Freno de zapata para vehiculos ferroviarios con una zapata de freno (6) sujetada en el bastidor del vagón en forra que se puede mover aproximadamente radialmente con respecto al eje de una rueda de vagón (9) a frenar, a través de al menos una pieza intermedia (3, 10) y de forma que puede girar alrededor de un eje de rotación (5) aproximadamente paralelo al eje de la rueda, estándo el eje de rotación (5) distanciado del centro de gravedad (S) de ]a zapata de freno (6), con un dispositivo de ajuste de la zapata de freno que actúa entre la pieza intermedia (3, 10) y la zapata de freno (6), que en una de las partes, es decir en la zapata de freno (6) ó en la zapata intermedia (3, 10) presenta al menos un taco de fricción (20) sujeto en forma desplazable, que está presionado por fuerza de resorte una superficie de fricción (28, 29) de la otra parte, es decir de la pieza intermedia (3, 10) o de la zapata de freno (6), impidiéndose por fricción, debido a los desplazamientos relativos entre el tacode fricción (20) y la superficie de fricción (28, 29), los giros relativos entre la pieza intermedia (3, 10) y la zapata de freno (6) alrededor del eje de giro caracterizado porque la superficie de fricción (28, 29) se ha configurado cono superficie en cuña que, cuando la zapata de freno (6) gira alrededor del eje de rotación (5), por efecto de la fuerza de gravedad, empuja hacia atrás al taco de fricción (20) en contra de su carga de resorte (18, 24) como superficie curvilínea en forma de arco alrededor del eje de giro (5).
