Abstract
resumo talão de pneumático para avião a invenção se refere a um pneumático (1) para avião que compreende dois talões (2) respectivamente destinados a entrar em contato com um aro (3) por pelo menos uma face radialmente interior do talão (4), e uma armadura de carcaça (5) que compreende pelo menos uma camada de carcaça (6) que liga os dois talões (2), a ou cada camada de carcaça (6), se enrolando em cada talão (2), em torno de um cordonel (7) que tem uma seção meridiana de centro (o). em cada talão (2), uma porção de aperto sob cordonel (8) se estende radialmente no interior de uma porção de armadura de carcaça (5) radialmente interior ao cordonel (7) até a face radialmente interior de talão (4). a porção de aperto sob cordonel (8) que compreende uma camada de superfície (9) destinada a entrar em contato com o aro (3) pela face radialmente interior de talão (4) e que tem uma rigidez de cisalhamento k1. os inventores se deram como objetivo diminuir a velocidade de formação de defeitos ou “pits” críticos sobre o assento de aro, para aumentar a duração de vida do aro e portanto o número de ciclos de utilização antes de retirada. de acordo com a invenção, a porção de aperto sob cordonel (8) compreende uma camada rígida (10), radialmente exterior e adjacente à camada de superfície (9), e uma camada deformável (11), radialmente exterior e adjacente à camada rígida (10) e radialmente interior e adjacente à porção de armadura de carcaça (5) radialmente interior ao cordonel (7), que tem uma rigidez de cisalhamento k3 no máximo igual a 0,3 vezes a rigidez de cisalhamento k1 da camada de superfície (9). 1/1
