Abstract

"PROCESSO PARA REDUZIR OS FENÈMENOS DE MICRO-DESLIZAMENTO PNEU/SOLO, E, PNEU PARA RODAS DE VEìCULOS". A presente invenção é relativa a um processo para reduzir os fenómenos de micro-deslizamento pneu/solo localizado em uma porção do ressalto de um pneu. A banda de rodagem 1 do pneu é dotada de um desenho em relevo que compreende uma pluralidade de nervuras circunferenciais 2, 4, 6 delimitadas por uma pluralidade correspondente de sulcos circunferenciais 3, 5 e tem sobre sua seção transversal um perfil de referência radialmente externo 7, 8, 20 que compreende um primeiro segmento retilíneo 20 localizado em no mínimo uma nervura circunferencial 2 de dita porção do ressalto, que se estende axialmente para fora além da borda A de dita porção do ressalto. Este processo consiste em designar à dita no mínimo uma nervura circunferencial 2 de dita porção do ressalto um perfil de seção transversal composto de um segundo segmento retilíneo 9 girado radialmente abaixado ao redor de um ponto que se situa sobre dito primeiro segmento retilíneo 20 em uma posição axialmente não interna à dita borda A de dita porção do ressalto.
