Abstract

The invention discloses a steel cord for tire reinforcement, which has an m+n structure, and includes a lower strand and an upper strand surrounding an outer circumferential surface of the lower strand. The lower strand includes a plurality of core wires, each of the plurality of core wires have a flat surface on a portion in which the plurality of the core wires come into contact with each other, and the plurality of core wires come into surface contact with each other through the flat surface, and wherein the upper strand includes about 2 to about 20 element wires, and the element wires are stranded so as to surround the outer circumferential surface of the lower strand with respect to a central axis, that is, an axis of a length direction of the lower strand. The steel cord for a tire reinforcement having a non-circular cross-section.

Description

technical field [0001] The invention relates to a steel wire rope for tire reinforcement. Specifically, as a steel wire rope for tire reinforcement including an m+n structure of down-twist and top-twist, the under-twist includes a plurality of core wires, and the core wires include a flat surface formed by extending in the length direction at least in one area, the multiple The core wires are stretched parallel to each other while at least a part of the flat surface is in contact with each other, and are twisted and then cold-rolled to enhance fatigue resistance, rubber permeability, and reliability. Steel cords for tire reinforcement. Background technique [0002] Tires need to have features such as light weight, durability, and high functionality such as excellent cornering and ride comfort in order to meet the needs of resource saving and long service life. To meet these conditions, various components have been invented that can be used for tire reinforcement. [0003] ...
