Abstract

1/1 resumo “pneumático comportando uma banda de rodagem constituída por várias misturas elastoméricas” pneumático, com armadura de carcaça radial, compreendendo uma armadura de vértice, ela mesma coberta radialmente por uma banda de rodagem reunida a dois talões por meio de dois flancos, a referida banda de rodagem compreendendo, pelo menos, duas camadas de misturas elastoméricas radialmente sobrepostas e apresentando uma taxa de abertura de entalhes inferior na sua parte central em relação às partes axialmente exteriores. uma primeira camada, de mistura elastomérica, da banda de rodagem é constituída por uma primeira mistura elastomérica formando uma parte estendendo-se pelo menos na zona do plano equatorial e de, pelo menos, duas partes axialmente exteriores formadas por uma segunda mistura elastomérica, a primeira mistura elastomérica apresentando uma nota z de macro dispersão superior a 65 e um valor máximo de tan(d), notado tan(d)max, inferior a 0,120, e o módulo complexo de cisalhamento dinâmico g 1% a 100°c da segunda mistura elastomérica apresentando um valor pelo menos 10% superior ao do módulo complexo de cisalhamento dinâmico g 1% a 100°c da primeira mistura elastomérica.
