Abstract
"INSERTO DE CUNHA COM RIGIDEZ VARIáVEL PARA PNEU QUE RODA VAZIO". Trata-se de um pneumático com lona radial que roda vazio 1000 para um veículo que tem uma banda de rodagem 1012, uma carcaça 1022 compreendendo pelo menos uma lona radial 1030 e dois costados 1016, sendo que cada um é reforçado por um inserto de cunha com formato crescente disposta circunferencialmente. Cada inserto tem uma seção porosa elastomérica 1042 embutida em uma camada mais rìgida elastomérica 1044 do inserto 1040. Quando o pneu está normalmente inflado, a seção porosa 1042 e assim o inserto como um todo, é flexível, proporcionando assim características confortáveis ao dirigir. Sob condições de rodar vazio (pneu desinflado), os poros na seção porosa 1042 entram em colapso e a seção porosa 1042 enrijece e assim o inserto como um todo se torna rígida o suficiente para suportar a carga do veículo.
