Title (EN) TYRE FOR HEAVY VEHICLES
(FR) PNEUMATIQUE POUR VEHICULES LOURDS
Abstract:
(EN) The invention concerns a tyre (1)with radial carcass reinforcement (2) comprising a crown reinforcement (4) consisting of at least two working crown plies (41, 42) of inextensible reinforcing elements, crossed from one ply to the next while forming with the circumferential direction angles ranging between 10° and 45°, itself radially capped with a running tread, and the axially widest working crown ply being radially inside relative to the other working crown layers. The tyre further comprises at least in each shoulder one layer (43) of circumferentially oriented reinforcing elements, the axially inner end of said additional layer being radially adjacent the edge of the radially outermost working crown ply, at least part of said additional layer being radially adjacent the edge of the axially widest working crown ply (41) and the axially outer end of said additional layer being radially inside relative to the axially widest crown working ply.
(FR) Pneumatique (1) à armature de carcasse radiale (2) comprenant une armature de sommet (4) formée d'au moins deux couches de sommet de travail (41,42) d'éléments de renforcement inextensibles, croisés d'une nappe à l'autre en faisant avec la direction circonf érentielle des angles compris entre 10° et 45°, elle-même coiffée radialement d'une bande de roulement, et la couche de sommet de travail axialement la plus large étant radialement intérieure aux autres couches de sommet de travail. Le pneumatique comprend additionnellement dans chaque épaule au moins une couche (43) d'éléments de renforcement, orientés circonf érentiellement, l'extrémité axialement intérieure de ladite couche additionnelle étant radialement adjacente au bord d'une couche de sommet de travail, au moins une partie de ladite couche additionnelle étant adjacente au bord de la couche de sommet de travail (41) axialement la plus large et l'extrémité axialement extérieure de ladite couche additionnelle étant radialement intérieure à la couche de sommet de travail axialement la plus large .
