Abstract

LONA DE CARCAÇA DE PNEUMÁTICO PARA VEÍCULO COM DUAS RODAS. O objetivo é uma estabilidade satisfatória da moto tanto em linha reta em alta velocidade quanto em curva com forte ângulo de cambamento. O pneumático (1) para veículo motorizado com duas rodas de tipo motocicleta que compreende uma banda de rodagem (2), ligada por dois costados (3) com dois talões (4), uma lona de topo (5) que compreende pelo menos uma camada de topo (51), uma lona de carcaça (6) que compreende pelo menos uma camada de carcaça redobrada (61), em que a camada de carcaça redobrada (61) compreende reforços paralelos entre si e que se enrolam, em cada talão, do interior para o exterior do pneumático, ao redor de uma haste (7), para formar uma redobra (8) que compreende uma extremidade livre (E), em que a camada de carcaça redobrada (61) compreende uma porção de topo (611) e uma porção lateral (612), em que a porção de topo (611) se estende axialmente entre uma primeira e uma segunda extremidade (E1, E'1), simétricas em relação ao plano equatorial (P), em que a porção lateral (612) se estende radialmente para o interior, a partir de uma primeira extremidade (E2) até uma segunda extremidade (E3). Os reforços da porção de topo (611) formam, com a direção circunferencial (X), um ângulo substancialmente constante igual a pelo menos 65°. Os reforços da porção lateral (612) formam, com a direção circunferencial (X), um ângulo crescente, desde a primeira extremidade (E2) até a segunda extremidade (E3), a partir de um ângulo interior de pelo menos 5° ao ângulo substancialmente constante, formado pelos reforços da porção de topo (611). Os reforços da redobra (8) formam, com a direção circunferencial (X), um ângulo igual em valor absoluto e de sinal oposto ao ângulo formado pelos reforços da porção lateral (612).
