TYRE BEAD WITH TEXTILE LAYERS |
摘要 |
<p>A tire has a carcass reinforcement ply, anchored within each bead by winding around an annular element whose tensile strength is less than the tensile strength necessary for a bead wire of a conventional tire of the same dimension, and an assembly of at least two textile bead reinforcement layers arranged in contact with the annular element, wherein the annular element has a tensile strength of between 3 and 5 times the tension imparted to the carcass reinforcement by the recommended inflation pressure, and an elongation at break between 2 and 6%, all the reinforcement layers having a tensile strength of between 0.5 and 1 time the tensile strength of the annular element, and the total of the tensile strengths of the annular element and of the assembly of the reinforcement layers being between 6 and 8 times the tension imparted to the carcass reinforcement.</p> |
