Description

用于车轮轮毂轴承的带凸缘的内圈
技术领域
本发明涉及一种带凸缘的内圈，特别地，涉及一种用于车轮轮毂轴承(/轮毂轴承)(wheel hub bearings)的带凸缘的内圈。
背景技术
已知类型的用于车轮轮毂轴承的带凸缘的内圈包括管状支撑主体和凸缘，管状支撑件用于车轮轮毂轴承，特别是用于车轮轮毂轴承的内圈，管状支撑件与轴承的旋转轴线同轴，凸缘横向于(/横切)旋转轴线并且设置有绕着轴线均匀地分布的多个螺纹通孔，并且凸缘具有：
-外环形安装表面，其上安装制动盘和轮辋(rim)，制动盘和轮辋通过插入到通孔中的带螺纹的螺丝固定，以及
-内环形表面，在轴向上面向滚动轴承的外圈。
凸缘具有均匀的基础轴向厚度，该基础轴向厚度由两个环形表面之间的轴向距离限定，并且被计算为承受车轮轮毂轴承的典型机械应力，并且凸缘还包括用于每个螺纹通孔的径向臂，该径向臂定位在凸缘的内表面上且位于面向外圈的位置处，并且从车轮轮毂轴承的安装肩部在径向上(/径向地/沿径向)向外延伸。每个径向臂用作用于至少在螺纹通孔的位置处加强凸缘的元件，并且与相邻的径向臂限定相应的增强盒，该增强盒的轴向厚度等于凸缘的上述基础轴向厚度。
在一些特定应用中，由于车轮轮毂轴承的重量可以改变车辆的悬架系统的响应，使其不容易跟随路面的不平整性，因此已经采用了轻型的带凸缘的内圈，这些内圈完全或几乎完全没有两个相邻的径向臂之间的增强盒。然而，使带凸缘的内圈整体减轻已经受挫，在一定程度上是因为径向臂的轴向厚度的增加，而径向臂的轴向厚度的增加对于确保车轮轮毂轴承仍然能够继续承受车轮轮毂轴承的典型机械应力是必须的。
发明内容
本发明的目的在于提供一种用于车轮轮毂轴承的带凸缘的内圈，其在具有重量非常轻的结构的同时仍然能够承受轮车轮轮毂轴承的典型机械应力。
根据本发明，描述了一种用于车轮轮毂轴承的带凸缘的内圈，其具有在所附独立权利要求中阐述的特征。
根据所附从属权利要求中阐述的特征描述本发明的其他优选和/或特别有利的实施方式。
附图说明
现在将参照附图描述本发明，附图示出了本发明的实施方式的一些非限制性示例，其中：
-图1是根据本发明的用于车轮轮毂轴承的带凸缘的内圈的立体图，为了清楚起见，移除了部分；
-图2是图1的用于车轮轮毂轴承的带凸缘的圈的截面，为了清楚起见，移除了部分。
具体实施方式
参照图1和图2，数字1表示用于车轮轮毂轴承的带凸缘的内圈的整体，车轮轮毂轴承在附图中仅部分地示出并且整体上由附图标记2表示。
在整个本说明书和权利要求书中，表示诸如“径向”和“轴向”的位置和方位的术语和表述应解释为与内圈1的中心轴线X有关。另一方面，诸如“轴向外部”和“轴向内部”的表述与组装状况有关，并且在当前情况下优选地分别与车轮侧和与车轮侧的相对侧有关。
内圈1包括管状主体(或管状支撑主体)4和凸缘(/法兰)(flange)5，管状主体4与轴线X同轴，凸缘5横切(/横向于)(transverse to)轴线X并且设置有绕着轴线X均匀地分布的多个螺纹通孔6。管状主体4也是车轮轮毂轴承2的一体部分，管状主体4限定内圈，并且具有车轮轮毂轴承的座圈(race)7，座圈7直接形成在管状主体4上且位于主体的肩部8处，密封件9安装在主体的肩部8上。在未示出但易于从以上描述推导出的带凸缘的内圈的替代实施方式中，车轮轮毂轴承2不是具有与管状主体4成一体的其自身的座圈7，而是包括设置有相应的座圈的两个内圈，两个内圈中的一个安装在管状主体4上且在轴向上位于肩部8的后面。
凸缘5具有轴向外安装环形表面11和内表面12，轴向外安装环形表面11上安装制动盘和轮辋(未示出)，制动盘和轮辋通过插入到螺纹通孔6中的带螺纹的螺丝(未示出)固定，内表面12在轴向上面向轴承2的外圈3并且形成通过内圈1的横切轴线X的轴向部分S，肩部8从轴向部分S在轴向上朝向外圈3延伸。凸缘5在径向上由具有直径C的外圆柱形表面14界定，并且包括用于每个通孔6的径向臂13(/对于每个通孔6包括径向臂13)，径向臂13在径向上从肩部8向外延伸但未到达圆柱形表面14，并且径向臂13在轴向上从表面12朝向外圈3延伸。
内圈1通过锻造形成，并且从一开始就具有径向臂13，径向臂13与肩部8和凸缘5形成单个主体，凸缘5在两个表面11和12之间并且在每对径向臂13之间具有基础轴向厚度A，基础轴向厚度A是均匀的并且小于肩部8的轴向厚度B。
根据本发明的实施方式，为了使带凸缘的内圈1既承受车轮轮毂轴承的典型机械应力又提供重量非常轻的结构以改善车辆悬架系统的响应，使其更加容易跟随路面的不平整性，因此使凸缘5的均匀的基础轴向厚度A的值为3mm，也就是说，该值远低于已知类型的带凸缘的内圈的凸缘中当前使用的值。为了实现本发明的主要结果，也就是说，对于等同的机械强度，带凸缘的内圈1的重量减轻，实验证据已经表明，该结果不仅在凸缘5的均匀的基础轴向厚度A的值为3mm的情况下获得，而且还在凸缘5的尺寸与肩部8的尺寸的比在正确指定的范围内的情况下获得，也就是说，在凸缘5的均匀的基础轴向厚度A与肩部8的轴向厚度B之间的比A/B的值具有在从最小0.15至最大0.4的范围内的值的情况下，类似地，也在凸缘5的均匀的基础轴向厚度A与凸缘5的直径C之间的比A/C的值具有在从最小0.018至最大0.03的范围内的值。
特别地，如果比A/B和A/C在相应的最小值以上，则带凸缘的内圈1的锻造不会出现问题，由于锻造材料在没有任何阻碍的情况下流动，因此能够形成没有裂纹的锻件。此外，再次，如果比A/B和A/C在相应的最小值以上，则带凸缘的内圈1有效地承受由所谓的车辆的“转弯”操纵所产生的侧倾力矩(tilting moment)，并且由于车辆自身的重量还承受轴向载荷和径向载荷。实际上，如果比A/B和A/C在它们相应的最小值以上，则凸缘5的尺寸与肩部8的尺寸之间的关系为使得尽管凸缘5相当纤薄(/薄)(rather slim)(即，凸缘5的厚度A的尺寸相当小)，至少在每对径向臂13之间的空间中的凸缘5相当纤薄，肩部8仍然有助于组件的整体刚性，因为肩部8的尺寸以新颖的方式适应这种纤薄，从而防止凸缘5的变形。
另一方面，如果比A/B和A/C在它们相应的最大值以下，则不会浪费用于锻造的原材料，由此降低原材料采购和生产的对应成本，并且带凸缘的内圈1的旋转质量也达到了最佳平衡。实际上，如果比A/B和A/C低于它们相应的最小值，则凸缘5的尺寸与肩部8的尺寸之间的关系为使得即使肩部8本身相当纤薄，凸缘5也不具有使其在径向上自由地悬突于(/悬挂超过/悬挂突出于/悬起突出于)(overhang beyond)肩部8后面并因此过于柔软的径向尺寸。
上述解决方案的优点是显而易见的：带凸缘的内圈1的重量减轻不仅使轴承制造商节省原材料和制造成本，而且还使车辆制造商降低CO2，这完全有利于环境并且因此确保符合日益严格的环境保护标准。另外，尽管在带凸缘的内圈1中实现了重量减轻，但应回想到，带凸缘的内圈1形成有的凸缘5的厚度A明显小于传统厚度，并结合了厚度A和厚度B之间以及厚度A和厚度C之间的创新尺寸比，仅仅由于这种创新尺寸的几何形状，带凸缘的内圈1在刚性和抗机械应力以及耐用性方面实现所需的性能，同时与目前市场上的产品相比，还可以提供更具竞争力的产品。
除了如上所述的本发明的实施方式之外，应当理解，存在许多其他变型。还应理解，所述实施方式仅作为示例提供，并不限制本发明的目的或其应用或其可能的构造。相反，尽管以上给出的描述能够使本领域技术人员根据其构造的至少一个示例来实施本发明，但是应当理解，可以设想所描述的组件的多种变型而不会因此脱离本发明的目的(/范围)，本发明的目的(/范围)由所附权利要求书限定、在字面上和/或根据其合法等同物进行解释。
