Abstract

PNEUMÁTICO COMPORTANDO UMA CAMADA DE ELEMENTOS DE REFORÇO CIRCUNFERENCIAIS. A invenção refere-se a um pneumático compreendendo uma armadura de vértice formada de, pelo menos, duas camadas de vértice de trabalho sendo, cada, formada de elementos de reforço inseridos entre duas camadas de calandragem de mistura borrachosa, cruzados de uma camada à outra fazendo, com a direção circunferencial, ?ângulos compreendidos entre 10° e 45° e a armadura de vértice comportando pelo menos uma camada de elementos de reforço circunferenciais. De acordo com a invenção, o módulo de elasticidade sob tensão a 10% de alongamento de, pelo menos, uma camada de calandragem de, pelo menos, uma camada de vértice de trabalho é inferior a 8,5 MPa e o valor máximo de tan(Delta), notado tan(Delta)max, da referida pelo menos uma camada de calandragem de, pelo menos, uma camada de vértice de trabalho inferior a 0,100.
