The invention discloses a steel cord, a manufacturing method thereof, and a tire. The steel cord comprises at least one strength element, wherein each strength element is provided with a periodic discontinuous crest curve; and the crest curves are arranged on one side or two sides or multiple sides of the steel cord. More gaps and opening degrees are arranged on one side or two sides or multiple sides, provided with the crest curves, of the steel cord, so that the rigidity is small; and the rigidity of the other sides of the steel cord is large, so that the steel cord has orientation. Meanwhile, through the crest curves, the gaps between the strength elements for forming the steel cord can be increased, so that the rubber permeability of the steel cord is improved, the wear of the strengthelements is reduced, and the corrosion resistance of the strength elements is improved.

    本发明公开了一种钢帘线、其制造方法及轮胎,所述钢帘线包含至少一个强度元件,所述强度元件具有周期性的不连续的凸形曲线,所述凸形曲线总是置于钢帘线的一侧或两侧或多侧。所述钢帘线在具有所述凸形曲线一侧或两侧或多侧由于具有更多的间隙和开度导致其刚度小,而所述钢帘线在其他侧的刚度大,从而使得所述钢帘线具有取向性。同时,凸形曲线可以增加组成钢帘线的强度元件之间的间隙,提高钢帘线的橡胶渗透性,减少强度元件的磨损,提高强度元件的抗腐蚀性能。
