Abstract

Un entramado de carcasa (3) que está formado situando sobre un soporte toroidal (11), una primera y segunda series de secciones en forma de bandas (13, 14) cortadas a medida a partir de un elemento similar a una banda continua (2a) y comprendiendo cada una de una serie de elementos en forma yuxtapuesta (15) incorporados dentro de una capa de material elastómero (18). Las secciones (13) de la primera serie están dispuestas secuencialmente en forma circunferencial separadas entre si a una distancia dada entre si, para formar partes laterales (13a) hasta las aletas extremas de las estructuras de refuerzo (4) en que se aplican los refuerzos. Las secciones de la segunda serie (14) están interpuestas cada una entre dos secciones de la primera serie (13), en espacios definidos, con las aletas extremas respectivas solapándose con las estructuras anulares (4). Cada parte anular (4) comprende un relleno elastómero (22) aplicado a una posición exterior radial con respecto a una inserción de anclaje anular sencilla (21) formada en al menos un elemento alargado bobinado en bobinas concéntricas superpuestas radialmente (21a).
