Abstract

Un tambor de construccion de neumatico, expansible, que tiene segmentos alternantes fijos (226, 326, 426) y de expansion (228, 328, 428) (por ejemplo, 24 de cada uno) en una seccion central (220, 320, 420) del tambor. Los segmentos de expansion se extienden axialmente y estan espaciados circunferencialmente entre si, y estan contorneados (tienen rebajos o ranuras) para alojar componentes de neumaticos tales como insertos de pared lateral. Dos mecanismos diferentes para expansion de la seccion central, se describen. Un primer mecanismo incluye dos elementos de cuna (358), que son moviles axialmente alejados entre si para expander la seccion central. Elementos de rampa (348) asociados con los segmentos de expansion (328), de esta manera puede moverse radialmente hacia afuera. Bandas; de hule o ligas (358) proporcionan una fuerza de restauracion para aplastar la seccion central. Un segundo mecanismo incluye dos anillos guia que son moviles axialmente entre si para expansion de la seccion central y lejos entre si para aplastar la seccion central. Articulaciones superpuestas (462, 464) se proporcionan entre los anillos guia y un elemento de soporte (448) que sostiene los segmentos de expansion (428).
