Abstract

"PNEU COM COSTADO TENDO PELO MENOS UM INSERTO DE BORRACHA INTERNO TENDO PROPRIEDADES FìSICAS GRADUADAS, COMPREENDIDO DE SEGMENTOS DE BORRACHA SOBREPOSTOS". Esta invenção refere-se a pneumáticos tendo um costado, que contém pelo menos um inserto de borracha anular interno. Em particular, esta invenção refere-se a pneumáticos que se baseiam convencionalmente em pressão de ar interna e a pneumáticos que se baseiam convencionalmente em pressão de ar interna, mas que têm uma capacidade de rodar por longas distâncias sem qualquer pressão de ar interna, isto é, a uma pressão de ar atmosférica ambiente, dependendo um pouco do posicionamento e da configuração do inserto de costado. Pelo menos um dos ditos insertos de costado é composto de dois segmentos, isto é, um segmento de borracha radialmente interno e um segmento de borracha radialmente externo. O segmento de borracha interno e o segmento de borracha externo têm propriedades físicas de módulo e dureza significativamente diferentes. Os segmentos são parcialmente sobrepostos entre si. Em um aspecto, cada um dos segmentos do inserto de costado de segmento duplo pode ser compreendido de vários tipos de composições de borracha contendo, por exemplo, uma dispersão de um polietileno de peso molecular ultra-alto e/ou uma dispersão de um compósito de amido / plastificante e/ou misturas de negro de fumo e sílica e/ou quaisquer materiais de reforço e de não reforço que podem ser usados para ajustar o gradiente de rigidez.
