Abstract

resumo “pneu que compreende um reforço de parede lateral adicional” pneu que compreende um reforço de carcaça radial (60) que consiste em elementos de reforço similares a filete (61) que têm um alongamento na ruptura ebc e uma força na ruptura fbc, dispostos em um passo pc e revestidos com borracha, satisfazendo a desigualdade: (i), em que fbc é expressa em newton, rs é o raio máximo (distância radial em relação ao eixo geométrico de rotação do pneu) da carcaça, re é o raio na largura axial máxima de pneu, e rt é o raio interno do fio de talão, o passo pc e os raios rs, re e rt estão em metros; sendo que cada parede lateral compreende um reforço adicional (120) que consiste em elementos de reforço similares a filete que têm um alongamento na ruptura eba e uma força na ruptura fba, dispostos em um passo pa e revestidos com borracha, de modo que a (ii), e ebc ? eba, esses parâmetros são determinados nos elementos de reforço após a extração do pneu curado. 1/1
