Abstract

BANDA DE RODAGEM DE PNEUMÁTICO PARA TRATOR AGRÍCOLA. A presente invenção se refere a um pneumático para veículo de uso agrícola, e mais especialmente, à banda de rodagem de tal pneumático. Ela tem como objetivo diminuir as agressões das faces de ataque das barrinhas de banda de rodagem, ao nível de suas extremidades axialmente exteriores, por restolhos residuais depois de colheita, e reduzir assim o risco de arrancamento das extremidades axialmente exteriores das barrinhas. Esse objetivo foi atingido por um pneumático que compreende uma banda de rodagem que compreende uma pluralidade de barrinhas, uma barrinha (3) que compreende, em qualquer plano axial (PXY) paralelo ao eixo de rotação do pneumático, um perfil de ataque (311) e um perfil de fuga (321). De acordo com a invenção, o ângulo (A) da reta (T) tangente ao perfil de ataque (311), em um ponto (M) do perfil de ataque (311), em relação a um plano equatorial (P), aumenta continuamente, a partir de um ponto (E) que é o mais axialmente exterior do perfil de ataque (311), quando a distância axial (L) entre o ponto (M) do perfil de ataque e o ponto (E) que é o mais axialmente exterior do perfil de ataque (311) aumenta, o ângulo (A) atinge um valor máximo (Am) em um ponto de inflexão (I) do perfil de ataque (311) e o raio de curvatura (R) em qualquer ponto (M) do perfil de ataque (311), posicionado axialmente entre o ponto (E) que é axialmente o mais exterior e o ponto de inflexão (I), é pelo menos igual a 0.4 vezes a altura da barrinha.
