Title (EN) TYRE COMPRISING CARCASS REINFORCING CORDS OF LOW PERMEABILITY AND TEXTILE THREADS ASSOCIATED WITH THE CARCASS REINFORCEMENT
(FR) PNEUMATIQUE COMPORTANT DES CÂBLES D'ARMATURE DE CARCASSE PRÉSENTANT UNE FAIBLE PERMÉABILITÉ, ET DES FILS TEXTILES ASSOCIÉS A L'ARMATURE DE CARCASSE
Abstract:
(EN) The invention relates to a tyre with a radial carcass reinforcement made up of at least one layer (2) of metal reinforcing elements, said tyre comprising a crown reinforcement (5) itself radially capped by a tread (6), said tread being connected to two beads by two sidewalls. According to the invention, the metal reinforcing elements of at least one layer of the carcass reinforcement (2) are unreinforced cords which, on a so-called permeability test, exhibit a throughput of less than 20 cm3/mn and at least one layer of the carcass reinforcement (2) being provided on at least one side with textile threads (10) directed mainly in a direction parallel to that of the metal reinforcing elements (7) of the said at least one layer of the carcass reinforcement (2), said textile threads (10) undulating about this main direction.
(FR) L'invention concerne un pneumatique à armature de carcasse radiale, constituée d'au moins une couche (2) d'éléments de renforcement métalliques, ledit pneumatique comprenant une armature de sommet (5) elle-même coiffée radialement d'une bande de roulement (6), ladite bande de roulement étant réunie à deux bourrelets par l'intermédiaire de deux flancs. Selon l'invention, les éléments de renforcement métalliques d'au moins une couche de l'armature de carcasse (2) sont des câbles non frettés présentant au test dit de perméabilité un débit inférieur a 20 cm3/mn et au moins une couche de l'armature de carcasse (2) étant pourvue sur au moins une face de fils textiles (10) orientés principalement selon une direction parallèle à celle des éléments de renforcement métalliques (7) de ladite au moins une couché dé l' armature dé carcasse (2), lesdits fils textiles (10) étant ondulés autour de cette direction principale.
