Description

用于子午线车辆轮胎的加强带束层包
技术领域
本发明涉及用于子午线车辆轮胎的加强带束层包，其缠绕在使用与机动车辆的轮胎中的胎面和胎体之间，增加转弯阻力并延长其的寿命。
背景技术
存在于如今所使用的子午线车辆轮胎中的带束层包中，有至少两个交叉带束层和周向的带束层加强件。所述交叉带束层由钢帘线组成并提供充分的侧面的和周向的刚度。然而，在所述层中存在大量的切割端。这些所述切割端负面地影响帘线-橡胶粘附，通过在该层的边缘处引起裂纹而引起轮胎动态退化。对于高速性能，这需要使用单独的带束层（冠带层，cap ply）。
欧洲专利文件号EP1000972（现有技术状态中已知的申请）公开了短纤维加强的橡胶加强带束层以便于在车辆轮胎中使用。借助于所述带束层增强了车辆的转向稳定性和滚动阻力。
欧洲专利文件号EP1310385（现有技术状态中另一个已知申请）公开的车辆轮胎在位于轮辋下的钢丝部件中包括以短纤维来加强橡胶层。所述短纤维指向轮胎的周向方向。
国际专利文件号WO 2005/002884（现有技术状态中另一已知申请）公开了一种包括两个常规的带束层（工作层）和周向冠带层的轮胎，其中该带束层由钢帘线组成，该周向冠带层具有交替的混合帘线和较低模量的帘线。
日本专利文件号JP2004217127是现有技术状态中另一已知申请，其呈现摩托轮胎包含常规钢缓冲层和具有交替的钢和芳纶帘线的额外层。
日本专利文件JP61119408是现有技术状态中的另一已知申请，其公开了具有小于1微米长度的短纤维用作带束层化合物中的填充料。通过降低剪切应变获得了增加化合物模量的结果。这些化合物与常规钢帘线一起使用。
发明内容
本发明的目的是提供用于子午线车辆轮胎的加强带束层包，其缠绕在轮胎的胎面和胎体之间。
本发明的另一目的是提供用于子午线车辆轮胎的加强带束层包，其在车辆应该具有良好的转弯刚度和高速性能的情形中增加轮胎的耐久性。
本发明的又一目的是提供用于子午线车辆轮胎的加强带束层包，其包括金属帘线和聚合物帘线两者。
本发明的再另一目的是提供用于子午线车辆轮胎的加强带束层包，其采用短纤维来加强。
附图说明
来实现本发明目的的用于子午线车辆轮胎的加强带束层包在附图中示出，其中：
图1是用于子午线车辆轮胎的有创造性的加强带束层包的横向截面图。
图2是有创造性的加强带束层包应用在上面的车辆轮胎的截面图。
附图中的部件的附图标记指定如下：
1. 加强带束层包
2. 周向带束层
21. 金属帘线（钢帘线）
22. 聚合物帘线
3. 橡胶层
S. 胎面
K. 胎体
L. 轮胎。
具体实施方式
有创造性的用于子午线车辆轮胎的加强带束层包（1）主要包括：
- 至少一个周向带束层（2），其通过将金属帘线（21）和聚合物帘线（22）一个接另一个布置使得聚合物帘线（22）将接着金属帘线（21），金属帘线（21）将接着聚合物帘线（22）来形成，
- 至少一个橡胶层（3），其覆盖在周向带束层（2）的上面和下面。
周向带束层（2）是在至少两个橡胶层（3）之间的条带层，并且其通过将包括扭捻单丝的金属帘线（21）和包括扭捻单丝的聚合物帘线（22）彼此挨着布置来获得。在本发明的优选实施例中，周向带束层条带（2）的宽度可在5-25 mm之间变化。基于帘线（21、22）表面，帘线（21、22）之间的距离是0-0.25 mm。
在本发明的优选实施例中，金属帘线（21）由钢材料构成。由尼龙6.6、尼龙4.6、聚对苯二甲酸乙二酯、聚萘二甲酸乙二醇酯（polyethylene naphthalate）帘线或芳纶-尼龙混合帘线用作聚合物帘线（22）。
在本发明的优选实施例中，钢帘线（21）通过扭捻具有0.12-0.45mm的直径的单丝来形成。所述单丝能够具有正常的、高的、超高的和特高的断裂强度（NT、HT、ST和UT）。聚合物帘线（22）通过扭捻具有0.1-0.5mm的直径的单丝来形成。
在本发明的优选实施例中，钢帘线（21）的捻度在50-200 tpm（每米捻回数），捻回长度（捻距）在5-20 mm之间。聚合物帘线（22）的捻度在50-500 tpm之间。钢帘线和聚合物帘线的捻回长度可以相同或者不同。
总端数（21、22）为50-250 epdm（每分米端数）。钢帘线（21）和聚合物帘线（22）的线密度能够相等或不同。
橡胶层（3）是包括短纤维的层，短纤维横向于周向带束层（2）布置使得其将抵抗带束层（2）的侧向压缩和膨胀。将两个橡胶层（3）和周向带束层（2）定位在轮胎（L）内部，使得它们将形成夹层结构。在本发明的优选实施例中，短纤维包括芳纶、人造纤维、聚酯和/或聚酰胺材料。用在所述橡胶层（3）中的短纤维的弹性模量在5-600 GPa之间。
具有创造性的用于子午线车辆轮胎的加强带束层包（1）位于轮胎（L）的胎面（S）和胎体（K）层之间。所述带束层包（1）消除了金属-金属微动磨损和由转弯期间车辆轮胎（L）中的侧向压缩而引起磨损问题，并且减轻了轮胎的重量。另外，在具有创造性的带束层包（1）中，没有切割端从而增加了轮胎（L）的耐久性和寿命。
在这些基本概念的范围内，有可能研发出具有创造性的用于子午线车辆轮胎的加强带束层包（1）的各个实施例。本发明不能限于在此文中描述的示例；本发明实质上是如权利要求所限定的。
