Abstract
''PNEU AGRìCOLA DE SERVIçO INDUSTRIAL''. Descreve-se um pneumático para agricultura (20) para um trator do tipo industrial ou veículo similar que tem uma pluralidade de barras centrais (60) e uma pluralidade de barras de ombro (40, 50). A pluralidade de barras centrais (60) são dispostas em uma fileira circunferencialmente contínua e se estendem através do plano equatorial (EP). Cada barra central (60) é similar em formato e orientação com relação a cada barra central circunferencialmente adjacente (60). Cada barra central (60) tem uma borda principal (1) e uma borda secundária (52). As bordas principais (51) de cada barra (60) são localizadas em um lado oposto ao plano equatorial com relação a borda secundária (52) da mesma barra central (60). A pluralidade de barras de ombro (40, 50) são divididas em primeira e segunda fileiras e projetadas radialmente para fora a partir da banda de rodagem interna (34) e se estendem a partir das bordas de banda de rodagem laterais (33A, 33B) na direção do plano equatorial do pneu (20). As barras de ombro (40, 50) têm uma extremidade axialmente interna (43, 53) sendo axialmente espaçadas a partir de uma extremidade principal (64) e de uma extremidade secundária (66) das barras centrais axialmente adjacentes (60). As barras (40, 50) em conjunto com as barras centrais (60) têm um raio de curvatura constante R1 e R2 em cada metade de banda de rodagem (32A, 32B). Os raios de curvatura R1 e R2 proporcionam uma capacidade de performance não direcional da banda de rodagem (32).'' AGRICULTURAL TIRE FOR INDUSTRIAL SERVICE ''. An agricultural tire (20) is described for an industrial type tractor or similar vehicle that has a plurality of central bars (60) and a plurality of shoulder bars (40, 50). The plurality of central bars (60) are arranged in a circumferentially continuous row and extend across the equatorial plane (EP). Each central bar (60) is similar in shape and orientation with respect to each circumferentially adjacent central bar (60). Each central bar (60) has a main edge (1) and a secondary edge (52). The main edges (51) of each bar (60) are located on a side opposite the equatorial plane with respect to the secondary edge (52) of the same central bar (60). The plurality of shoulder bars (40, 50) are divided into first and second rows and project radially outwardly from the inner tread (34) and extend from the side tread edges (33A, 33B) towards the equatorial plane of the tire (20). The shoulder bars (40, 50) have an axially internal end (43, 53) being axially spaced from a main end (64) and a secondary end (66) of the axially adjacent central bars (60). The bars (40, 50) together with the central bars (60) have a constant radius of curvature R1 and R2 in each tread half (32A, 32B). The radii of curvature R1 and R2 provide a non-directional performance capability of the tread (32).
