Abstract

REFORÇO DE CARCAÇA PARA UM PNEU DE AVIÃO. A invenção se refere à melhoria da resistência do reforço de carcaça (5) de um pneu (1) de avião, na região de flexão da junta (3) contra o aro (4). Este pneu inclui um reforço de carcaça (5) com duas famílias de camadas (51, 52) que se estendem entre as duas juntas, a primeira família incluindo ao menos uma camada que se enrola, do interior para o exterior do pneu, em torno de uma haste (6), a extremidade livre (E1) do enrolamento (551) sendo radialmente externa ao ponto (E) mais radialmente externo da haste, a segunda família incluindo ao menos duas camadas que se estendem, em cada junta (3), do exterior para o interior do pneu, até suas extremidades respectivas (E2) radialmente interiores a uma reta axial (Dv) que passa pelo centro (O) da haste e axialmente interiores a uma reta radial (D2) que passa pelo centro da haste a uma distância axial (d2) pelo menos igual a 5 mm. As camadas de carcaça (52) da segunda família são axialmente interiores a ao menos um enrolamento (511 ).
