Abstract

pneumático que compreende uma armadura de topo formada por pelo menos duas camadas (41, 43) de topo de trabalho de elementos de reforço e por pelo menos uma camada (42) de elementos de reforço circunferenciais, uma camada c de mistura de borracha sendo disposta entre as extremidades das camadas de topo de trabalho. de acordo com a invenção, a banda de rodagem apresenta pelo menos um recorte de orientação oblíqua (7), a profundidade, medida em um pneumático novo do dito pelo menos um recorte de orientação oblíqua sendo superior ou igual a 40 % da espessura da banda de rodagem, a razão da largura medida no fundo do dito pelo menos um recorte de orientação oblíqua sobre a largura medida na superfície da banda de rodagem do dito pelo menos um recorte de orientação oblíqua sendo superior a 1.2, a distância d entre a extremidade da camada de trabalho que é axialmente a mais estreita e a camada de trabalho separada da camada de trabalho que é axialmente a mais estreita pela camada c de mistura de borracha sendo tal que 1.1ø < d < 2.2ø, ø sendo o diâmetro dos elementos de reforço da dita pelo menos uma camada de elementos de reforço circunferenciais, e em um plano meridiano, a espessura da camada c de mistura de borracha sendo substancialmente constante na largura axial compreendida entre a extremidade axialmente interior da camada c e a extremidade da camada de trabalho que é axialmente a mais estreita.
