具体实施方式
图4示出了根据本发明的包括轴承密封件的被构造为车轮轴承组件的轴承组件(bearing assembly)，该轴承密封件包括第一金属板元件16，该金属板元件16包括附接区域18，金属板元件通过附接区域18附接到轴承组件的轴承内圈20。轴承组件的滚动元件52抵接轴承内圈并且抵接轴承组件的外圈36，并与内圈和外圈一起形成滚动元件轴承，其中，在滚动元件轴承的操作期间，圈绕着轴线48相对于彼此旋转。外圈压入到毂35中。轴承密封件包括密封元件22，密封元件22由弹性体构成并且附接到金属板元件上。密封元件的区域26被轴承密封件的弹簧元件24径向向外压，该弹簧元件24被构造为螺旋弹簧。由此，密封元件的密封唇40被压抵由金属板组成且被压入到毂35中的组件(component)38上，密封唇40在径向上指向外部。由于密封元件与金属板元件16的附接以及由弹簧元件施加的力，密封元件的区域28在轴向上压抵组件38的区域30，区域30在径向方向和周向方向上延伸。
此外，密封元件包括相对于滚动元件轴承在轴向上指向外部且在径向上指向内部的密封唇32。密封唇32接触轴承密封件的即使在滚动元件轴承的操作期间也总是相对于外圈静止的组件(component)34。组件34被压入组件38中。
在可选的示例性实施方式中，组件34、组件38被构造为一体件。在其他可选的示例性实施方式中，用于确定外圈的转速的脉冲轮(impulse wheel)额外地承担组件34的功能(/作用)。
密封元件的另一密封唇41接触组件38的径向内部区域44。
另外，轴承密封件的重心50布置在轴承内圈的孔46的外侧。因此，轴承密封件突出超过轴承内圈的轴向端表面，从而可以使轴承内圈的轴向长度保持最小(/尽可能小)，另外可以节省安装空间，此外可以将标准设计用于轴承内圈，这是特别具有成本效益的。由于轴承密封件与轴承内圈的良好连接，因此轴承密封件提供高的运行精度和非常好的密封效果。
在本发明的可选的实施方式中，金属板元件在其朝向滚动元件弯曲(turned)的轴向端部处被翻边(/凸缘化)(flanged)，从而实现增强和加固，如此实现较好保持于轴承内圈。
组件34改善对来自外部的水和灰尘的密封。还应该提到的是，除了密封唇32之外，密封元件的另一密封唇抵接组件34。组件34也可以由附接到轮毂的金属板代替。如果组件38和组件34构造为一体件，则在轴承密封件的安装结束时进行翻边(/凸缘化)(flanging)，以形成密封唇32所抵接的区域。
油或脂可以用作滚动轴承的润滑剂。特别是在使用油的情况下，通过根据本发明的轴承密封件实现牢固且持久的密封。
