Abstract

ARMADURA DE TOPO DE PNEUMÁTICO CONSTITUÍDA POR DUAS CAMADAS DE TOPO DE TRABALHO E UMA CAMADA DE ELEMENTOS DE REFORÇO CIRCUNFERENCIAIS. A invenção se refere a um pneumático, que compreende uma armadura de topo (4) constituída por duas camadas de topo de trabalho (41, 42) 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 de elementos de reforço circunferenciais (43) são as únicas que estão presentes para constituir a armadura de topo (4) por pelo menos 80 % da largura da banda de rodagem (5), o valor absoluto da diferença entre os valores absolutos dos ângulos 2 e 1 sendo superior a 4°, 2 sendo maior do que 1 em valor absoluto, o ângulo médio ¿ satisfazendo a relação 14+131*exp(-L/100) < < 28+110*exp(-L/100), e a razão (R = dc-dE) / ds) sendo tal que 0.05 < R < 3.
