Cords for reinforcing heavy vehicle tires

摘要

A cable is disclosed that can be used to reinforce a crown protection ply and/or a stiffener ( 9 ) in tires for heavy industrial vehicles. Also disclosed are composite fabrics that can be used as crown protection plies and/or as stiffeners ( 9 ) in such tires, and the tires themselves. The cable comprises three strands twisted together in helix of pitch p 2 , each consisting of two metallic wires twisted together in helix of pitch p 1 , these wires having diameters (d 1 , d 2 ), (d 1 ', d 2 '), (d 1 '', d 2 '') for the strands, respectively, such that the cable satisfies the following conditions: (i) 0.25 < D1 < 0.45 (ii) 0.25 < D2 < 0.45 (iii) 0.25 < d1' < 0.45 (iv) 0.25 < d2' < 0.45 (v) 0.25 < d1'' < 0.45 (vi) 0.25 < d2'' < 0.45 (vii) 2 < p1 < P2 < 10.
