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 forming with the circumferential direction angles ranging between 10° and 45°, at least one protective layer (44) being radially outside the working crown plies, said crown reinforcement being radially capped with a running tread (5). The tyre further comprises in each shoulder at least one layer (43) of circumferentially oriented reinforcing elements, the axially inner end of said additional layer being radially adjacent and outside relative to the radially outermost working ply (42) and said axially inner end of the additional layer being radially adjacent and inside at least part of the protective layer (44).
(FR) Pneumatique (1) à armature, de carcasse radiale (2) comprenant une armature de sommet (4) formée d'au moins deux couches de sommet (41,42) de travail d'éléments de renforcement inextensibles, croisés d'une nappe à l'autre en faisant avec la direction circonférentielle des angles compris entre 10° et 45°, au moins une couche de protection (44) étant radialement à l'extérieur des couches de sommet de travail, ladite armature de sommet étant coiffée radialement d'une bande de roulement (5) . 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 et extérieure a la couche de travail radialement la plus à l'extérieur (42) et ladite extrémité axialement intérieure de la couche additionnelle étant radialement adjacente et intérieure au moins à une partie de la couche de protection (44) .
