Abstract

PNEU E BANDA DE RODAGEM DE PNEU COM RANHURAS DE CURVATURA DEFINIDA. Um pneu tem uma banda de rodagem, com a banda de rodagem tendo uma pluralidade de elementos de banda de rodagem que contatam o chão, criando uma superfície de banda de rodagem e pelo menos um dos elementos tem uma ranhura no mesmo. Nos planos paralelos à superfície de banda de rodagem, a configuração de uma porção radial externa da ranhura é definida por uma curvatura não linear contínua, a curvatura tendo pelo menos um raio R. O valor do raio R da curvatura de ranhura aumenta a partir da superfície de banda de rodagem para uma base da ranhura, e a base da ranhura tem uma configuração definida por um raio R tendo um valor de infinidade.
