Abstract

Ce revêtement est caractérisé en ce que : a. La bande de roulement 1 est réalisée en élastomère à base de caoutchouc, d'isoprène et/ou de caoutchouc butadiène-styrène qui, après vulcanisation, présente des caractéristiques d'hysterésis et de dureté inférieures à celles de la matière qui constitue la carcasse; b. La carcasse 2 est constituée en élastomère à base de polyuréthanne et ne comporte aucun élément d'armature en dehors des tringles 3 disposées dans les talons; c. Cette carcasse présente des valeurs du rapport H/C comprises entre 0,35/1 et 0,60/1, H désignant la hauteur de la section et C représentant la largeur transversale maximale de la carcasse proprement dite, une fois montée, gonflée et considérée sans la bande de roulementThis coating is characterized in that: a. The tread 1 is made of an elastomer based on rubber, isoprene and / or butadiene-styrene rubber which, after vulcanization, has hysteresis and hardness characteristics lower than those of the material which constitutes the carcass; b. The carcass 2 is made of an elastomer based on polyurethane and does not include any reinforcing element apart from the bead wires 3 placed in the heels; vs. This carcass has values of the H / C ratio of between 0.35 / 1 and 0.60 / 1, H denoting the height of the section and C representing the maximum transverse width of the carcass itself, once mounted, inflated and considered without the tread
