Abstract

BANDA DE RODAGEM DE PNEUMÁTICO PARA UM VEÍCULO PESADO COM UMA RESISTÊNCIA ÀS AGRESSOES MELHORADA. A presente invenção tem como objeto uma banda de rodagem de pneumático para veículo pesado de uso misto e visa melhorar a resistência do topo do pneumático depois de uma retenção de seixos na banda de rodagem. A banda de rodagem (1) compreende vazios (3) que compreendem uma primeira porção de vazio (31) radialmente exterior de tipo ranhura que tem uma largura W11 ao nível da superfície de rodagem (2), uma largura W12 ao nível do fundo de ranhura (311), e uma profundidade H1, e uma segunda porção de vazio (32) radialmente interior de tipo incisão, que tem uma largura W12 e uma profundidade H2 e que desemboca no fundo de ranhura (311) a uma distância E em relação à superfície média (S1) da ranhura (31) De acordo com a invenção, a distância E é pelo menos igual à largura W12 do fundo de ranhura (311) dividida por 6.
