Abstract

Une structure à motifs pour bande de roulement de pneumatique comprend des blocs de motifs centraux et des blocs de motifs d'épaulement disposés de chaque côté. Les blocs de motifs centraux comprennent des blocs de motifs en bande et des blocs de motifs obliques. Au moins un bloc de motif en bande est formé en continu au centre de la bande de roulement et des gorges principales à motifs divers se coupent symétriquement et s'étendent obliquement vers l'extérieur à partir des deux côtés du bloc de motifs en bande. Des blocs de motifs obliques sont formés entre les gorges principales. Des gorges secondaires transversales reliées aux gorges principales sont réparties sur les blocs de motif d'épaulement et les blocs de motifs obliques. Les blocs de motifs en bande diminuent la résistance au roulement, réduisent la consommation d'énergie et améliorent la tenue de cap. Les blocs de motifs obliques améliorent le confort de marche et atténuent le bruit des pneumatiques. Les blocs de motifs d'épaulement empêchent l'abrasion excentrique du pneu roulant sur le sol. Les gorges principales et les blocs de motifs d'épaulement assurent une bonne capacité d'évacuation de l'eau et améliorent la capacité des pneumatiques AV et AR d'épouser la même trace. Ce pneumatique améliore la maniabilité pendant la marche, la stabilité sur sol sec ou mouillé et le confort de marche, ce qui confère à un véhicule tout terrain de bonnes performances globales sur une chaussée en dur.
