Abstract

L'invention concerne une enveloppe de bandage pneumatique. Selon l'invention, elle a,en coupe transversale, une bande de roulement, une carcasse radiale 2, ayant au moins un pli en cordes d'acier, et une ceinture de renforcement 8 à plusieurs plis radialement internes 13, 14, 15 et un pli d'entrave 16 radialement externe d'une étendue transversale plus faible que les plis radialement internes pour les serrer fermement sur la zone de couronne de la carcasse; les plis radialement internes ont des cordes formant un angle de biais de 16 à 32 degrés par rapport à une ligne centrale circonférentielle de la bande de roulement, et l'angle de biais du pli d'entrave 16 par rapport à la ligne centrale circonférentielle de la bande de roulement est d'à peu près 5 à 15 degrés , pour maintenir la zone de couronne de la carcasse 2 à une forme sensiblement plane. L'invention s'applique notamment aux pneumatiques pour poids lourds.The invention relates to a tire casing. According to the invention, it has, in cross section, a tread, a radial carcass 2, having at least one ply of steel cords, and a reinforcing belt 8 with several radially internal plies 13, 14, 15 and a radially outer hinder ply 16 of a smaller transverse extent than the radially inner plies to clamp them firmly to the crown area of the carcass; the radially internal plies have cords forming a bias angle of 16 to 32 degrees to a circumferential center line of the tread, and the bias angle of the drag ply 16 to the circumferential center line of the tread is approximately 5 to 15 degrees, to keep the crown area of carcass 2 in a substantially planar shape. The invention applies in particular to tires for heavy vehicles.
