Abstract
描述了在轮胎中形成密封剂层的方法,其中所生产的轮胎是平衡的。该方法包括以下步骤:提供轮胎;已经在胎冠下方的轮胎内侧喷涂密封剂层,其中随着轮胎旋转,相对于轮胎中部圆周平面以0度角喷涂密封剂层。
Description
技术领域
本发明总体上涉及轮胎制造,并且更具体地涉及用于形成具有后固化密封剂的轮胎的方法。
背景技术
具有轮胎穿孔密封剂的充气轮胎或具有轮胎穿孔密封性能的轮胎构造是轮胎领域的技术人员已知的。通常,这种轮胎包括通常喷涂在轮胎内侧的一层密封剂。就轮胎不平衡而言,密封剂层通常代表以最大临界直径添加到轮胎的显著质量。密封剂的现有技术叠层通常导致相对于轮胎中心平面的不对称图案,并且可能导致轮胎动态失衡。因此,期望得到用于形成具有没有动态失衡的密封剂层的轮胎的改进的方法和设备。
发明内容
定义
“高宽比”表示轮胎断面高度与其断面宽度的比值。
“轴向的”和“轴向地”表示平行于轮胎旋转轴线的线或方向。
“胎圈”或者“胎圈芯”通常意指包括环形抗拉构件的轮胎的部分,径向内胎圈与将轮胎保持至轮辋相关联,其由帘布层帘线包绕并且成形为带有或不带其它增强元件如胎圈芯包布、胎跟加强层、三角胶芯、护趾胶和胎圈包布。
“带束层结构”或者“增强带束层”意指由平行帘线构成的至少两个环形层或者帘布层,帘线经过编织或者未经编织,位于胎面下方,非锚定至胎圈,并且具有相对于轮胎的赤道平面在17度至27度的范围内的左帘线角和右帘线角。
“交叉帘布层轮胎”表示胎体帘布层中的加强帘线以相对于轮胎赤道面约25度至65度角斜对角地穿过轮胎从胎圈至胎圈延伸,层帘线在交替的层内以相反的角度延伸。
“缓冲层”或“轮胎缓冲层”表示与带束层或带束层结构或增强带束层相同。
“胎体”是指轮胎帘布层材料和其他轮胎部件的层叠,其被切割成适合于拼接或已经拼接成圆柱形或环形的长度。在将其硫化以形成模制轮胎之前,可以将其他组分添加至胎体。
“周向的”通常意指垂直于轴向方向沿着环形胎面的表面的周界延伸的线或方向;其还能够表示各组邻近圆形曲线的方向,这些圆形曲线的半径限定胎面的轴向曲率,如在横截面中所观察的。
“帘线”表示加强线束之一,包括纤维,其用于加强帘布层。
“内衬”表示形成无内胎轮胎的内表面的弹性体或其它材料的一层或多层,其含有轮胎内的充气流体。
“镶件”是指通常用于增强防爆轮胎的侧壁的增强;其也指位于胎面下面的弹性体镶件。
“帘布层”表示由涂覆有弹性体的径向配置或以其它方式平行布置的帘线构成的帘线加强层。
“径向的”和“径向地”意指径向地朝向或者远离轮胎的旋转轴线的方向。
“子午线帘布层结构”表示一个或多个胎体帘布层,或其至少一个帘布层具有相对于轮胎的赤道面定向在65度与90度之间的角度的加强帘线。
“子午线轮胎”意指带束或周向地限制的充气轮胎,其中帘布层具有以相对于轮胎赤道面在65度与90度之间的帘线角从胎圈延伸至胎圈的帘线。
“侧壁”意指在胎面与胎圈之间的轮胎的部分。
“层压结构”是指由一层或多层轮胎或弹性体部件例如内衬,侧壁和任选的帘布层构成的未硫化结构。
附图说明
将通过示例并参照附图描述本发明,在附图中:
图1是轮胎密封剂喷涂设备和轮胎的示意图的前视图;
图2是轮胎和轮胎密封剂喷涂设备的喷嘴的特写图;
图3示出了使用轮胎密封剂喷涂设备的螺旋缠绕的密封剂叠层;
图4A示出了螺旋缠绕的密封剂叠层的特写图,而图4B示出了平衡的螺旋缠绕的密封剂叠层;
图5示出了使用轮胎密封剂喷涂设备的本发明的密封剂叠层;
图6示出了本发明的密封剂叠层的特写图。
具体实施方式
图1和图2示出了可旋转地安装在密封剂分配架20中的轮胎T。密封剂分配架20具有用于保持轮胎的轮胎夹持器30和用于增大轮胎宽度的轮胎扩展器40。密封剂分配架20还包括具有施加杆60的机器人臂50。施加杆60具有密封剂分配喷嘴70。机器人臂50可沿轮胎的轴向方向移动施加杆60以分配一层密封剂。图3示出了当分配喷嘴沿平行于轮胎的旋转轴线的方向平移时,分配喷嘴以螺旋缠绕构造80施加一层密封剂。图4A示出了螺旋缠绕构造的特写图。螺旋缠绕构造80以通常在3-6度(从轮胎赤道平面测量)范围内的微小角度螺旋缠绕。端部82、84、86、88,如交叉阴影线所示,导致轮胎失衡。图4B示出了螺旋缠绕构造100,其中端部82、84、86、88被去除,从而形成了平衡的密封剂构造。
图5-6示出了具有平衡的密封剂层的轮胎的本发明的第二实施例。密封剂层构造200在图6中示出。密封剂层200由连续的密封剂条带的多个缠绕形成。密封剂层200具有第一缠绕201,该第一缠绕201具有起点部分200和终点部分204,其中,密封剂以0度取向或“直”的形式在起点和终点之间以条施加。密封剂喷涂取向相对于轮胎中部圆周平面L为0。第一缠绕201保持在0度取向,直到大约在轮胎旋转的320-358度的范围内(即,小于360度旋转),其中第一密封剂缠绕的终点204在过渡部分210中成角度。过渡部分212的终点或第二缠绕214的起点与第一缠绕201的起点202轴向间隔开。密封剂层由多个缠绕201、214、220、230、240、250、260形成,其相对于轮胎中部圆周平面以0度定向并形成直部分。每个缠绕的每个直部分从0度缠绕到小于360度,并具有连接到可选过渡部分的终点204。过渡部分成角度。
根据本文所提供的本发明的说明,本发明的变化是可能的。虽然为了说明主题发明,已经示出了一些有代表性的实施例和细节,但是对于本领域技术人员来说显而易见的是,在不脱离本主题发明的范围的情况下可以在其中进行各种改变和修改。因此,应该理解,可以在所描述的特定实施例中进行改变,这些改变将在由下列所附权利要求所限定的本发明的完整预期范围内。
