Abstract

pneumático (1) para veículo pesado de tipo de engenharia civil que compreende uma parte de topo prolongada de um lado e de outro por flancos (3), os flancos e os talões, essa parte de topo compreendendo uma banda de rodagem (2) e uma armadura de topo, essa última sendo situada radialmente entre a banda de rodagem (2) e uma armadura de carcaça (4), a armadura de topo compreendendo uma armadura de proteção (6), uma armadura de trabalho (5) e uma armadura adicional (7), a armadura de proteção (6) compreendendo pelo menos uma camada de proteção (61, 62) que compreende reforços metálicos elásticos que formam, com a direção circunferencial, um ângulo pelo menos igual a 10º, a armadura de trabalho (5) compreendendo pelo menos duas camadas de trabalho (51, 52) que compreendem reforços metálicos, cruzados de uma camada de trabalho para a seguinte e que formam, com a direção circunferencial, um ângulo no máximo igual a 60º, a armadura adicional (7), centrada axialmente no plano mediano equatorial do pneumático, compreendendo pelo menos uma camada (71, 72) que tem uma largura axial no máximo igual a 0,9 vezes a menor das larguras axiais das pelo menos duas camadas de trabalho (51, 52) e compreendendo reforços metálicos que formam, com a direção circunferencial, um ângulo no máximo igual a 25º, a banda de rodagem (2) sendo provida de um desenho de escultura que compreende pelo menos duas ranhuras (10) de orientação circunferencial, esse pneumático sendo tal que a distância axial média entre as duas ranhuras (10) mais próximas do plano mediano equatorial é superior à largura axial máxima da armadura adicional (7) medida entre as extremidades das camadas dessa armadura adicional que são as mais afastadas axialmente do plano mediano equatorial.
