Title (EN) TYRE HAVING LOW-PERMEABILITY CARCASS REINFORCEMENT CABLES, AND TEXTILE CORDS ASSOCIATED WITH THE CARCASS REINFORCEMENT
(FR) PNEUMATIQUE COMPORTANT DES CABLES D'ARMATURE DE CARCASSE PRESENTANT UNE FAIBLE PERMEABILITE, ET DES FILS TEXTILES ASSOCIES A L'ARMATURE DE CARCASSE
Abstract:
(EN) The invention relates to a tyre with a radial carcass reinforcement (2) consisting of at least one layer of metallic reinforcing elements (7), said tyre comprising a crown reinforcement (5) which is itself covered radially by a tread, said tread being joined to two beads by two sidewalls. According to the invention, the metallic reinforcing elements (7) of at least one layer of the carcass reinforcement are unhooped cables which exhibit in the so-called permeability test a flow rate of less than 20 cc/min and at least one layer of the carcass reinforcement (2) being provided on at least one face with at least one layer of textile cords (10) of rectilinear orientation and said textile cords (10) forming an angle with the direction of the metallic reinforcing elements of said layer or layers of the carcass reinforcement of more than 10°.
(FR) L'invention concerne un pneumatique à armature de carcasse radiale (2), constituée d'au moins une couche d'éléments de renforcement métalliques (7), ledit pneumatique comprenant une armature de sommet (5), elle-même coiffée radialement d'une bande de roulement, ladite bande de roulement étant réunie à deux bourrelets par l'intermédiaire de deux flancs. Selon l'invention, les éléments de renforcement métalliques (7) d'au moins une couche de l'armature de carcasse sont des câbles non frettés présentant au test dit de perméabilité un débit inférieur à 20 cc/mn et au moins une couche de l'armature de carcasse (2) étant pourvue sur au moins une face d'au moins une couche de fils textiles (10) d'orientation rectilignes et lesdits fils textiles (10) formant un angle avec la direction des éléments de renforcement métalliques de ladite au moins une couche de l'armature de carcasse supérieur à 10°.
