The present invention relates to a two-strand cord for use as a reinforcing member in a belt strap of a vehicle pneumatic tire, consisting of only two yarns of which the ends are twisted together, in which a first yarn has a Z value of 600 mN/tex or more, and in which a second yarn has a Z value of 75 mN/tex or less and a Y value of 150 mN/tex or less, wherein Z is a force normalized to the linear density of the yarn when 1% elongation is obtained in a force-elongation map, wherein Y is a force normalized to the linear density of the yarn when 4% elongation is obtained in the force-elongation map, and wherein a quotient X of the linear density of the first yarn divided by the linear density of the second yarn is in a range from 1.0 to 1.3.

    本发明涉及一种在车辆充气轮胎的带束箍带中用作加强构件的双股帘线,其由仅两条末端捻绕在一起的纱线组成,其中第一纱线具有600mN/tex或更大的Z值,并且其中第二纱线具有75mN/tex或更小的Z值和150mN/tex或更小的Y值,其中Z是在力‑伸长率图中获得1%伸长率时的归一化为纱线线密度的力,其中Y是在力‑伸长率图中获得4%伸长率时的归一化为纱线线密度的力,并且其中该第一纱线的线密度除以该第二纱线的线密度的商X在从1.0至1.3的范围内。
