土木工学型の重車両用のタイヤビード

Document Type and Number:

Japanese Patent JP5732068

Kind Code:

B2

Abstract:

The invention relates to Technique for improving the durability of the beads of a radial tire for a heavy vehicle of the civil engineering type, by reducing the rate of spread of cracks which are initiated on the axially external face of the turned-back portion of carcass reinforcement and then spread through the coating and filling polymer materials. A transition element (28), made of a transition polymer material, is in contact, via its axially internal face, with the coating polymer material of the axially external face of the turned-back portion of carcass reinforcement (21b) and, via its axially external face, with the filling polymer material (26), and the elastic modulus at 10% elongation of the transition polymer material is somewhere between the respective elastic moduli at 10% elongation of the coating polymer material and of the filling polymer material.
