一种用于橡胶加强的钢帘线,包括具有数目为m的第一组芯单丝和具有数目为n的第二组鞘单丝,m为3或4,芯单丝形成螺旋,芯单丝不是绞捻在一起并且基本上平行或者芯单丝具有大于300mm的绞捻节距;第二组和第一组彼此绞捻,并且鞘单丝在与芯单丝的螺旋的相同方向上形成扁平螺旋,并且鞘单丝具有帘线绞捻节距,在任何横截面处,钢帘线存在两个相邻芯单丝之间的至少一个空隙。钢帘线具有改善的耐磨性,并且可有助于轮胎的重量的减小。

    A steel cord for rubber reinforcement comprises a first group of core filaments (105) having a number of m and a second group of sheath filaments (110) having a number of n, m is three or four, the core filaments (105) are forming a helix, the core filaments (105) are not twisted together and being substantially parallel or the core filaments (105) have a twist pitch being more than 300 mm; the second group and the first group are twisted with each other, and the sheath filaments (110) are forming a flattened helix in the same direction of the helix of the core filaments (105), and the sheath filaments (110) have a cord twist pitch, at any cross-section of the steel cord, at least one interstice between two adjacent core filaments (105) is present. The steel cord has improved abrasion resistance and can contribute to the reduction of the weight of the tire.
