Abstract

PNEUMÁTICO, E, UTILIZAÇÃO DO MESMO A invenção refere-se a um pneumático comportando pelo menos uma estrutura de reforço de tipo carcaça (6, 7) formada de pelo menos uma camada de elementos de reforço paralelos entre si e formando com a direção circunferencial ângulos compreendidos entre 65° e 87°, e comportando sob a banda de rodagem uma estrutura de reforço de topo (8) constituída de pelo menos uma camada de elementos de reforço fazendo com a direção circunferencial ângulos compreendidos entre 10° e 45°, referida camada de trabalho sendo radialmente externa à estrutura de reforço de tipo carcaça. De acordo com a invenção, nos flancos, o pneumático comporta pelo menos duas porções de camadas de armadura de carcaça axialmente adjacentes, os elementos de reforço das referidas porções de camadas de armadura de carcaça sendo orientados de um lado ao outro de um plano meridiano; pelo menos ao nível do plano equatorial, os elementos de reforço da armadura de carcaça formam um ângulo com a direção circunferencial inferior a 80°, os elementos de reforço de pelo menos uma camada de trabalho são cruzados com os elementos de reforço da estrutura de reforço de tipo carcaça em um ângulo superior a 40°, e quando o pneumático comporta pelo menos duas camadas de trabalho, os elementos de reforço de duas camadas de trabalho sobrepostas são cruzados de uma camada à seguinte em um ângulo de, no máximo, 10°.
