Description

用于充气车辆轮胎的带束层的钢丝帘线制成的增强层
技术领域
本发明涉及用于充气车辆轮胎的一种增强层，其中这些增强物是钢长丝或者钢丝帘线，它们基本上彼此平行并且间隔开地被安置在增强层内并且包埋在橡胶原材料内。
背景技术
钢长丝和钢丝帘线作为用于充气车辆轮胎钢的增强层中的增强物是已知的。增强层的组件的一个例子是充气车辆轮胎的缓冲带束层。形成了汽车充气车辆轮胎中的带束层组件的支撑帘布层通常是由作为增强物的钢丝帘线来增强的。当今结合在充气小汽车轮胎中的许多支撑帘布层由结构2×0.30mm的钢丝帘线组成、这些钢丝帘线被包埋橡胶混合物中并且彼此平行延伸。该2×0.30mm帘线构造的意思是0.30mm直径的两个长丝被扭绞在一起以便形成一根帘线，并且这样该帘线具有约0.60mm的直径。有时候，还使用了帘线构造，其中帘线由一种螺旋包绕物包围。
术语“长丝”是指一根单一的线。术语“帘线”是指扭绞在一起的两根或更多根长丝。术语“螺旋包绕物”是指一根通常更细的线，它在一个相反的扭绞方向上围绕该帘线而缠绕。
轮胎的发展一直在不断努力着以便实现轮胎重量的进一步的减小以及轮胎的滚动阻力的进一步的减小。
发明内容
因此，本发明的目的是提供一种充气车辆轮胎，它的重量被进一步减小了并且滚动阻力也被进一步减小了。
该目的通过在此增强层中的长丝实现，这些长丝具有小于0.24mm的直径并且在所有的情况下将最多两根长丝扭绞以便形成一个帘线。
增强物直径的减小实现了以下效果：要求一个更小体积的橡胶用于将增强物包埋在该增强层之内，由此来减小轮胎的滚动阻力。增强物直径的减小和橡胶的更小体积还具有以下效果：节省了轮胎的重量，由此其滚动阻力也被减小了。例如2×0.22mm的帘线构造具有约0.44mm的帘线直径。此减小的帘线直径具有以下效果，即，该增强层是更薄的并且这样更小体积的橡胶是必要的用于将钢丝帘线包埋在这个层之内。如果需要的话，通过使用减小的增强物直径而引起的该增强层的减小的强度可以在该充气车辆轮胎上通过本领域的普通技术人员已知的措施进行补偿。
这些帘线由钢构成。可以使用极限抗拉强度等级NT、HT、ST或UHT的钢，其中例如，以下是关于0.20mm的长丝直径的特征
-NT＜3400MPa
-HT＞＝3400MPa
-ST＞＝3650MPa
-UHT＞＝4000MPa。
在一个优选实施方案中，这些长丝具有的直径为0.1mm-0.24mm、特别优选直径为0.175mm。
方便的是每个增强物是包括一根单一长丝的单丝。其结果是，增强物的直径再一次被减小了，并且因此必要的用于包埋该层中的橡胶的体积也被再一次减小了。
在一个特别优选的实施方案中，每个增强物是具有结构2×0.175mm的钢丝帘线。
根据本发明的增强层可以用于气动汽车、厢式货车、轻型货车、以及重型货车的轮胎中。
