Abstract

PNEUMáTICO COM BANDA DE RODAGEM CIRCUNFERENCIAL DE BORRACHA TENDO UM ELEMENTO DE CONTROLE DO LADO EXTERNO. A invenção relaciona-se a um pneumático tendo uma banda de rodagem circunferencial de uma configuração de cobertura/base composta de uma camada de cobertura de borracha da banda de rodagem externa com uma superfície de rolamento da banda de rodagem e uma camada de base de borracha da banda de rodagem subjacente, em que a dita camada de cobertura da banda de rodagem é composta de duas zonas adjacentes longitudinais, a saber, uma zona de cobertura da banda de rodagem primária e um elemento (zona) de controle do lado externo lateral secundário. A zona de cobertura da banda de rodagem primária e o elemento de cobertura da banda de rodagem do lado externo lateral proporcionam uma gradação significativa dos módulos de armazenagem dinâmicos (G<39>) a frio, a 25<198>C, e dos valores de tangente delta, a quente, a 100<198>C, ainda módulos de armazenagem dinâmicos (G<39>), a quente, similares, a 60<198>C. A zona de cobertura da banda de rodagem primária e o elemento de cobertura da banda de rodagem de controle do lado externo lateral estão suportando carga no sentido de estenderem-se a partir da superfície de rolamento da banda de rodagem radialmente para dentro, até a camada de borracha de base da banda de rodagem (sem zonas) unitária. A camada de cobertura da banda de rodagem de borracha com zonas e a camada de base da banda de rodagem de borracha unitária são um compósito de banda de rodagem integral em um sentido de serem coextrudadas. Em um aspecto da invenção, a composição de borracha da zona de cobertura da banda de rodagem primária é rica em sílica e a composição de borracha do elemento do lado externo, lateral, é rica em negro-de-fumo e as quais adicionalmente proporcionam uma gradação do teor de reforço de carga; proporcionam uma gradação de razão de sílica para negro-de-fumo e proporcionam uma gradação de teor de borracha de cis 1,4-polibutadieno.
