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 other forming with the circumferential direction angles ranging between 10° and 45°, itself radially capped with a running tread (5), the axially widest working crown layer (41) being radially inside the other working crown layers and a layer (P) of cohesive rubber mixtures being arranged between at least part of the working crown plies. The invention is characterized in that the tyre further comprises in each shoulder at least one layer (43) of circumferentially oriented reinforcing elements, the axially inner end of the additional layer being radially adjacent the edge of a working crown ply (41, 42), at least part of said additional layer being radially and/or axially adjacent the edge of the axially widest working crown ply and the ratio the modulus of elasticity of the layer (P) over the modulus of elasticity of the liner of the working layer adjacent the additional layer ranging between 0.5 and 1.
(FR) Pneumatique (1) à armature de carcasse radiale (2) comprenant une armature de somme (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°, elle-même coiffée radialement d'une bande de roulement (5), la couche de sommeil de travail axialement la plus large (41) étant radialement intérieure aux autres couches de sommet de travail et une couche (P) de mélanges caoutchouteux cohésifs étant disposée entre au moins une partie des couches de sommet de travail, le pneumatique comprend additionnellement dans chaque épaule au moins une couche (43) d'élément de renforcement orientés circonférentiellement, l'extrémité axialement intérieure de ladite couche additionnelle étant radialement adjacente au bord d'une couche de sommet de travail (41, 42) au moins une partie de ladite couche additionnelle étant radialement et/ou axialement adjacente au bord de la couche (P) sur le module d'élasticité de la couche de calandrage de la couche de travail adjacente à la couche additionnelle étant compris entre 0.5 et 1.
