Abstract

Un conjunto de freno de tambor de rueda de vehículo incluye un conjunto accionador de freno mejorado que tiene un diseño de excéntrica y rodillo estabilizante. La excéntrica y el rodillo incluyen una superficie de centrado y guía de cooperan para evitar el movimiento relativo entre la excéntrica y los rodillos en una direccion axial que es generalmente perpendicular a una direccion de movimiento de las zapatas de freno producida por la excéntrica que mueve los rodillos. Los rodillos y las zapatas de freno están provistos de superficies de centrado y guía similares cooperantes para evitar el movimiento relativo indeseable entre las zapatas y los rodillos. Las superficies de centrado y guía incluyen paredes laterales no paralelas de tal manera que se prevea una cuña de contacto superficial. Las superficies de centrado y guía proporcionan una característica de centrado y aumentan la cantidad de contacto superficial y la cantidad de rozamiento deseable experimentado en el sistema.
