Abstract

Perfeccionamientos en dispositivos de accionamiento de frenos, especialmente para un freno de tambor con zapatas internas y que comprende un cilindro de rueda de funcionamiento hidráulico que tiene por lo menos un pistón, cuyo pistón puede ser empujado hacia fuera para accionar el freno pro presión hidráulica que actúa en el cilindro de la rueda o por un conjunto de cuña que se desplaza transversal al cilindro, o por ambas cosas a la vez, cuyo conjunto de cuña tiene una cuña y rodillos que actúan entre la cuña y superficies contrarias paralelas a las superficies de la cuña, alojándose los rodillos en una jaula montada para efectuar un movimiento relativo a lo largo de la cuña y dos muelles opuestos que actúan contra la jaula para determinar una posición de referencia sin carga de la jaula sobre la cuña, caracterizados porque está previsto un tope para que, al retroceder la cuña para soltar el freno, la jaula encuentre el tope y quede retenida para comprimir uno de los muelles mientras que la cuña continúa su movimiento de retroceso.
