【発明の名称】ゴム補強用スチールコード及びラジアルタイヤ
Document Type and Number:
Japanese Patent JP2863999
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce both a steel cord for reinforcing rubber by spirally winding a side wire on a core strand having a flat continuous wave form formed by bundling plural wires and a lightweight radial tire excellent in durability, having buckling resistance even in reduction in the amount of the cord, by using the steel cord. SOLUTION: A wire which comprises a carbon steel containing 0.80-0.85wt.% carbon and has relationship of Z>=-200d+400 between tensile strength Z (kgf/ mm<2> ) before twisting and a wire diameter (d) (mm) is used. Plural core wires 1a are twisted or bundled approximately in parallel to give a core strand 1 having a flat continuous wave. One or more wires 2 each having a diameter different from that of the core wires 1a are spirally wound around the core strand and twisted to give the objective steel cord for reinforcing rubber in which the cord section forms a flat shape approximately in the same direction in the longer direction. This steel cord is used as at least a part of a belt part and a carcass part to form the objective radial tire.
