Abstract

pneumático (1) que compreende três camadas de trabalho; de acordo com a invenção, os elementos de reforço das duas camadas de trabalho (42, 43) que são radialmente as mais exteriores são cruzados de uma camada para a outra formando assim com a direção circunferencial ângulos compreendidos entre 20 e 45º, os ângulos, formados com a direção circunferencial, dos elementos de reforço da camada de trabalho que é radialmente a mais interior sendo compreendidos entre 15 e 20º, os elementos de reforço das duas camadas de trabalho (41) que são radialmente as mais interiores sendo orientados de acordo com a mesma direção em relação à direção circunferencial, a diferença entre os ângulos dos elementos de reforço das camadas de trabalho que são radialmente as mais interiores é superior a 10º, as larguras (l42, l43) das duas camadas de trabalho (42, 43) que são radialmente as mais exteriores sendo superiores a 0,7 vezes a largura (l5) da banda de rodagem e a largura (l41) da camada de trabalho (41) que é radialmente a mais interior sendo estritamente inferior a 0.7 vezes a largura (l) da banda de rodagem.
