Abstract

pneumático que compreende uma armadura de topo constituída por duas camadas de topo de trabalho (4) de elementos de reforço, e por pelo menos uma camada (43) de elementos de reforço circunferenciais. de acordo com a invenção, as duas camadas de topo de trabalho (41, 42) e a dita pelo menos uma camada (43) de elementos de reforço circunferenciais estão sozinhas presentes para constituir a armadura de topo em pelo menos 40 % da largura da banda de rodagem, o valor absoluto da diferença entre os valores absolutos dos ângulos a2 e a1 sendo superior a 12º, a2 sendo maior do que a1 em valor absoluto, o ângulo médio a satisfazendo a relação 14 + 131 * exp(-l/100) < a < 28 + 110 * exp(-l/100), e a razão de utilização do potencial de ruptura f2/fr2 da camada de trabalho (42) que é radialmente a mais exterior sendo inferior a 1/6.
