Abstract

本实用新型一种钢帘线,由钢丝股编捻而成,钢丝股由钢丝(1)编捻而成,它由二根截面为四边形的钢丝股捻成,每根钢丝股由四根钢丝(1)捻成,钢丝股编捻成的钢帘线的截面为二个四边形排列的形状。本实用新型伸长率高、抗冲击性能强、适合轮胎轻量化。

Description

一种钢帘线
技术领域
本实用新型涉及一种作为充气轮胎中保护层用的高伸长钢帘线
背景技术
一般钢帘线4*4*0.24mm由于捻距较大,伸长率较小,质量较重,当它作为轮胎带束层时,抗冲击力不强,影响轮胎的使用寿命,而且不适合轮胎轻量化要求。
发明内容
本实用新型提供一种伸长率高、抗冲击性能强、适合轮胎轻量化的钢帘线
本实用新型采用如下技术方案,一种钢帘线,由钢丝股编捻而成,钢丝股由钢丝编捻而成,它由二根截面为四边形的钢丝股捻成,每根钢丝股由四根钢丝捻成,钢丝股编捻成的钢帘线的截面为二个四边形排列的形状。
本实用新型中所述的钢帘线的捻距在5.5-7.5mm,钢丝股的捻距在3.0-3.5mm;所述的钢丝股与钢帘线的捻向为同向捻;所述的钢帘线破断力大于1330N,破断伸长率大于3.5%。
采用上述技术方案后,钢帘线和钢丝股的捻距较小,它的伸长率超过4%,钢丝股的钢丝之间为线接触,强度高,钢丝股之间易渗胶,耐腐蚀。将这种结构的钢帘线用于子午线轮胎的带束层,作为轮胎的保护层,可以提高轮胎的抗冲击负荷能力,防止轮胎胎体受损,同时又能防止带束层帘线因穿刺和歌口造成湿气的渗入,引起钢帘线腐蚀损坏,极大提高了轮胎的安全性和使用寿命,同时该结构替代4*4*0.24mm结构降低了轮胎厂的成本,适合了轮胎的轻量化要求。
附图说明
图1为本使用新型一种钢帘线的结构示意图
具体实施方式
根据图1所示,本实用新型由八根钢丝编捻而成,钢丝1的直径为0.24mm。先将四根钢丝1捻制成截面为四边形的钢丝股,钢丝1与钢丝1之间为线接触;再将二根钢丝股编捻成钢帘线,钢丝股和钢帘线的捻向为S向,钢丝股的捻距为5.5-7.5mm,钢帘线的捻距为3.0-3.5mm,在本实施方式中的钢丝股的捻距为3.5mm,钢帘线的捻距为7.5mm。
