Abstract

一种钢帘线,用于充气轮胎中,由芯线和钢丝编捻而成,钢丝的截面为圆形,芯线是由3根钢丝编捻而成的一股截面为三角形的芯线,芯线与外层9根钢丝编捻成截面为圆形的钢帘线,其强度高,占轮胎重量比小,符合轮胎轻量化要求。

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带束层用的钢帘线。
背景技术
虽然金属精炼和拉拔技术有了长足的发展,但含碳量较高的碳钢仍未用于轮胎钢帘线中,随着含碳量的增加,生产线材时,很难控制碳偏析及非金属夹杂的分布和尺寸,易产生缺陷,生产钢帘线时线材无法承受很大的拉伸变形,为提高钢帘线的强度,钢丝的直径较粗,难以满足轮胎轻量化要求。
发明内容
本实用新型的目的是提供一种高强度,占轮胎重量比重小的钢帘线。
本实用新型的技术方案如下:一种钢帘线,由芯线和钢丝线编捻而成,钢丝的截面为圆形,芯线是由3根钢丝编捻而成的一股截面为三角形的芯线,芯线与外层9根钢丝编捻成截面为圆形的钢帘线。芯线与钢帘线的捻向相同。
本实用新型具有紧密的结构,在保持相同的增强作用下,钢帘线直径可以减小,从而减轻轮胎中钢帘线的重量,降低轮胎生产成本。
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,本实用新型一种钢帘线,由芯线和钢丝编捻而成,钢丝线的截面为圆形,芯线是由3根钢丝编捻成的一股截面为正三角形的芯线,芯线与外层9根钢丝编捻成截面为圆形的钢帘线,钢丝直径为0.20mm,芯线和钢帘线的捻向均为S向,芯线的捻距为6.3mm,钢帘线的捻距为12.5mm。

Claims (2)

1、一种钢帘线,由芯线和钢丝编捻而成,钢丝的截面为圆形,其特征在于所述芯线是由3根钢丝编捻而成的一股截面为三角形的芯线,芯线与外层9根钢丝编捻成截面为圆形的钢帘线。
2、根据权利要求1所述的钢帘线,其特征在于芯线和钢帘线的捻向相同。
