Description

一种编织钢丝带束层结构及其应用 技术领域
本发明属于编织钢丝帘布技术领域，特别涉及一种编织钢丝带束层结构及其应用。
背景技术
带束层是轮胎的重要组成部分，是指在子午线轮胎胎面下沿胎面中心线圆周方向的材料层，由钢丝帘线与对应胶料压延覆胶而成。除了起箍紧胎体的作用外，缓冲外部冲击也是带束层的主要功能，同时它还是主要受力部件，承担约60％～75％的轮胎应力。
全钢子午线轮胎一般由3～4层带束层组成，半钢子午线轮胎一般由2～3层带束层组成。第一带束层(最内层)为过渡层，由于胎体角度较大，接近90°，而靠近胎面的带束层角度(带束层帘线轴方向与轮胎周向所之间的夹角，简称为帘线角)较小，为此需要有一个过渡，过渡层帘线角一般在45°～65°之间；第二到三层为工作层，帘线角为10°～30°之间，第四层为保护层，其帘线角与工作层相仿，也有采用0°的。一般采用叠层式结构，各层帘线角相互交错排列(如图1所示)，以第二和第三层为例，图1中2表示第二层，3表示第三层，OO’表示为胎冠中心线，L’表示带束层宽度，21和31分别表示为位于第二层和第3层中的帘线，21帘线角为α’，31帘线角为β’，d为同一带束层中相邻钢帘线间距。
现有技术带束层裁切后边缘会露出没有镀层的钢丝端头，粘合力受到影响，且端头并未固定，端部受力和变形较大。为了加强带束层 端部设计，减少胎肩部位应力集中引起的脱层，有轮胎公司研制了折叠式和包边式带束层，但在轮胎滚动中，因为被折叠的帘线易于在弯折处断裂，轮胎耐久性不太令人满意。
发明内容
为解决现有技术的不足，本发明提供一种编织钢丝带束层结构及其应用，该编织钢丝带束层为一层与轮胎周向一致的编织钢丝帘布层，是由一层编织的钢丝网压延而成。本发明简化了多层带束层的铺设步骤，有效地约束轮胎肩部变形，优化带束层应力、胎面接地压力分布，提高了耐久性能、耐磨性能、负荷性能，降低了油耗。
为实现上述目的，本发明采用的技术方案为：

进一步的，所述编织钢丝带束层结构还包括若干C股，C股纵向上下交错的搭织于A股与B股之间。
进一步的，A股与编织成结构的纵向轴呈α编织角，B股与编织成结构的纵向轴呈β编织角，C股与编织成结构的纵向轴平行。

进一步的，A股按α编织角、间距d1编织到边部后，换向β按角度、间距d2编织，与此同时，B股由β编织角、间距d2编织到边部后换向α按角度、间距d1编织，循环往复。
进一步的，所述若干C股以编织成结构的纵向中心轴为轴对称分布。

一种编织钢丝带束层结构的应用，所述编织钢丝带束层结构用于制造轮胎。
进一步的，所述编织钢丝带束层结构单独使用或替代第二-第四带束层贴合在第一带束层上使用。
与现有技术相比，本发明具有以下优点：
