Patent

CA 2359325

The invention concerns a tyre (1) with a radial body ply reinforcement comprising, viewed in meridian cross-section, at least a first bead (12), whereof the seat (12B) is inclined outwards, the bead (12) heel being axially inside and being reinforced by at least a reinforcing element (14), whereas the bead toe is axially outside and comprises a profile (3)of rubber mix in the form of a wedge delimited by two sides (31, 32), said mix having a Shore A hardness higher than the Shore A hardness level(s) of the rubber mixtures (7) and (6) radially above. The invention is characterised in that the radial body ply reinforcement (13) is wound in the bead around the annular element (14) from inside outwards to form a ply turn-up (130), whereof the end is located axially outside a straight line P2 perpendicular to the axis of rotation and passing through the centre of gravity of the meridian cross-section of the element (14), and axially inside and radially outside the straight line P1 supporting the radially external side (31) of the profile (3).

Pneumatique (1) à armature de carcasse radiale (13) comprenant, vu en section méridienne, au moins un premier bourrelet (12), dont le siège (12B) est incliné vers l'extérieur, le talon de bourrelet (12) étant axialement à l'intérieur et étant renforcé par au moins un élément de renforcement (14), alors que la pointe de bourrelet est axialement à l'extérieur et comprend un profilé (3) de mélange caoutchouteux sous forme de coin délimité par deux côtés (31, 32), ledit mélange ayant une dureté Shore A supérieure à la (aux) dureté(s) Shore A des mélanges caoutchouteux (7 et 6) radialement au- dessus, caractérisé en ce que l'armature de carcasse radiale (13) s'enroule dans le bourrelet autour dudit élément annulaire (14) en allant de l'intérieur à l'extérieur pour former un retournement (130), dont l'extrémité est localisée d'une part axialement à l'extérieur d'une droite P2 perpendiculaire à l'axe de rotation et passant par le centre de gravité de la section méridienne de l'élément (14), et d'autre part axialement à l'intérieur et radialement à l'extérieur de la droite P1 supportant le côté radialement externe (31) du profilé (3).
