Abstract

本发明涉及包括至少一个密封单元(10)和附接于密封单元的至少一个脉冲轮(12)的组件。所提出的是，脉冲轮以过盈配合和/或材料结合的方式附接于密封单元。

Description

组件
技术领域
本发明涉及根据方案1的前序部分的组件。
背景技术
已知(一种)包括密封单元和脉冲轮的组件。脉冲轮被压在密封单元中。在轴承组件中，还已知的是布置有密封单元，该密封单元在一个轴向端处密封轴承组件、与轴承组件的脉冲轮在空间上间隔开。
发明内容
本发明的目的特别是包括提供一种效率提高的上述类型的组件。该目的通过独立方案1的特征有创造性地实现，而本发明的有利设计和其它发展可以在从属方案中得到。
本发明涉及包括至少一个密封单元和至少一个脉冲轮的组件。
所提出的是，脉冲轮以过盈配合和/或材料结合(/材料锁合)(materiallybonded)的方式附接于密封单元。根据本发明，能够实现效率提高。特别的是，能够实现节约型设计。特别是，与将密封单元压在脉冲轮中的构造相比，能够由仅有一种尺寸的、薄的、有成本效益的金属板形成脉冲轮，使得能够直截了当地产生用于确定脉冲轮的转速的足够强的信号。
所述组件优选包括至少一个弹性元件(/弹性体元件)(elastomer element)，弹性元件至少部分地布置在脉冲轮与密封单元的金属制组成部件之间。由此，能够实现脉冲轮和金属制组件的制造公差不会叠加(add up)。此外，在最后将脉冲轮附接到金属制组成部件之前，通过弹性元件能够使脉冲轮定中(centering)。另外，能够实现的是，在通过加压(pressing)将组件附接在轴承组件的毂(hub)与内圈之间的情况下，该摩擦配合附接的方法不取决于脉冲轮，特别是不取决于其直径，这是因为通过弹性元件能够补偿在压入毂与内圈之间期间朝向密封单元的径向内侧发生的压缩。
其它优点可以从附图的以下描述得到。附图中描绘了本发明的示例性实施方式。附图、说明书和权利要求书包含组合的数个特征。本领域技术人员还将有利地考虑单个特征，并且还将单个特征组合成其它有意义的组合。

具体实施方式
图1示出了处于如下状态的本发明的组件的一部分：组件能够通过直接压入(/压嵌)(pressing-in)而安装在毂与圆锥滚子轴承的内圈之间，其中该毂和内圈是例如卡车的车轮轴承组件的两部分。组件包括密封单元10和脉冲轮12，其中脉冲轮以过盈配合(/干涉配合)(interference-fit manner)的方式(特别是相对于(/关于)脉冲轮的轴向14)附接于密封单元。脉冲轮不能沿脉冲轮的径向或轴向14远离密封单元地移动。
密封单元包括弹性元件(/弹性体元件)(elastomer element)16和由板金(/金属片材)(sheet metal)形成的组成部件18。金属板被构造成旋转对称，并且具有最大直径大于脉冲轮的环形区域24。借助于区域24和弯曲区域26，组成部件18围绕脉冲轮。脉冲轮被形成为烧结圈(sintered ring)。
弹性元件部分地布置在脉冲轮与组成部件18之间。更确切地说，弹性元件的环形区域22布置在所述组件与脉冲轮之间。区域22包括位于其径向内侧的区域20，区域20由凸块(nub)形成。从区域20开始，弹性元件包括沿周向彼此均匀间隔开的其它凸块。
除了用于补偿公差，弹性元件还起到一定的使脉冲轮定中(certain centering)的作用。
此外，弹性元件经由(/利用)其它凸块30抵靠脉冲轮的沿径向和周向延伸的表面。
在轴承组件中，脉冲轮用于确定毂的转速。
在可选的示例性实施方式中，脉冲轮不以过盈配合的方式附接于组成部件，而是固定地焊接于组成部件。
