Abstract

本实用新型公开了一种钢帘线,由钢丝股编捻而成,钢丝股由钢丝编捻而成,它由三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不规则形状。钢帘线的捻距小于6.5mm,钢丝股的捻距小于4mm,钢丝股与钢帘线的捻向相同。采用上述结构钢帘线伸长率高、抗冲击性能强。

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型钢帘线。
背景技术
一般钢帘线由于捻距较大,伸长率较小,当它作为轮胎带束顶层时,抗冲击力不强,影响轮胎的使用寿命。
发明内容
本实用新型提供一种伸长率高、抗冲击性能强的钢帘线。
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,它由三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不规则形状。
在本实用新型中所述钢帘线的捻距小于6.5mm,钢丝股的捻距小于4mm;所述钢丝股与钢帘线的捻向相同。
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,耐腐蚀性强。将这种结构的钢帘线用于子午线轮胎的带束顶层,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钢帘线因穿刺和割口造成湿气的渗入,引起钢帘线腐蚀损坏,极大地提高轮胎的安全性和使用寿命。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步地说明。
图1为本实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12根钢丝编捻而成,钢丝的直径为0.22mm。先将4根钢丝编捻成截面为四边形的钢丝股,钢丝与钢丝之间为线接触;再将三根钢丝股编捻成钢帘线,钢丝股和钢帘线的捻向均为S向,钢丝股的捻距小于4mm,钢帘线的捻距小于6.5mm,在本实施方式中钢丝股的捻距为3.15mm,钢帘线的捻距为6.3mm。
