Title (EN) TYRE FOR HEAVY VEHICLES
(FR) PNEUMATIQUE POUR VEHICULES LOURDS
Abstract:
(EN) The invention concerns a tyre with radial carcass reinforcement comprising a crown reinforcement consisting of at least two working crown plies (241, 242) of inextensible reinforcing elements, crossed from one ply to the next forming with the circumferential direction angles ranging between 10° and 45°, itself capped with a running tread, said running tread being assembled by two beads via two sidewalls. The invention is characterized in that the tyre further comprises at least in each shoulder a layer of reinforcing elements (243), mutually parallel and substantially perpendicularly oriented relative to the reinforcing elements of the working ply radially adjacent the additional layer, said additional layer being radially adjacent the edge of the radially outer working ply, and the axially inner end of said additional layer being located at a distance from the equatorial plane of the tyre equal to the distance separating from said plane the end of the working ply to which it is adjacent.
(FR) L'invention concerne un pneumatique à armature de carcasse radiale comprenant une armature de sommet formée d'au moins deux couches (241, 242) de sommet 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, ladite bande de roulement étant réunie à deux bourrelets par l'intermédiaire de deux flancs. Selon l'invention, le pneumatique comprend additionnellement au moins dans chaque épaule une couche (243) d'éléments de renforcement, parallèles entre eux dans la couche et orientés sensiblement perpendiculairement par rapport aux éléments de renforcement de la couche de travail radialement adjacente à ladite couche additionnelle, ladite couche additionnelle étant radialement adjacente au bord de la couche de sommet de travail radialement extérieure, et l'extrémité axialement extérieure de ladite couche additionnelle étant située à une distance du plan équatorial du pneumatique égale à la distance séparant dudit plan l'extrémité de la couche de travail à laquelle elle est adjacente.
