Abstract

armadura de reforço de um pneumático de turismo. a invenção visa uma boa resistência à penetração e à perfuração de seu topo por objetos estranhos, com uma arquitetura de reforço simples e leve. de acordo com a invenção, a camada de guarnecimento (71) tem uma força em ruptura por mm de largura axial de camada de guarnecimento fr pelo menos igual a 35 dan/mm e tem um módulo de extensão secante ma pelo menos igual a 250 dan/mm, para uma força aplicada f igual a 15 % da força em ruptura fr da dita camada de guarnecimento (71). a armadura de trabalho (6) compreende uma só camada de trabalho (61) da qual os reforços de trabalho formam, com a direção circunferencial (yy?), um ângulo at pelo menos igual a 30º e no máximo igual a 50º. os reforços de carcaça da pelo menos uma camada de carcaça (81) formam, com a direção circunferencial (yy?) e no plano equatorial (xz), um ângulo ac2 pelo menos igual a 55º e no máximo igual a 80º e que tem uma orientação oposta àquela do ângulo at dos reforços de trabalho, de modo a que os reforços de carcaça e os reforços de trabalho constituam uma triangulação.
