Description

车轮轴承单元
技术领域
本发明涉及一种车轮轴承单元，特别是用于机动车的车轮轴承单元。
背景技术
滚动铆钉铆接的车轮轴承单元在过去被大量应用于轿车。在未被驱动的车轮轴承单元中，根据标准与车辆侧的能够接管大部分轴向侧的密封功能的盖件结合使用。在与感应的车轮轴承单元(例如能够检测或测量车轮转数的车轮轴承单元)结合使用的情况下，这种盖封闭件是有利的。通过这种盖封闭件不再需要另外的密封件。具有被安置传感器的盖件至少在传感器区域中由非磁性材料构成，因此通常使用不锈钢盖。
由专利文献DE 11 2011 100 942 T5已知一种具有盖件的车轮轴承单元，其中盖件具有被压入外圈的车辆侧的端部的部段。在外圈和盖件之间设有弹性部件，该弹性部件通过盖件被完全地按压并且完全地弹性变形。
专利文献EP 2 047 131 B1公开一种车轮轴承单元，这种车轮轴承单元具有用于密封轴承的盖件。盖件通过部段安置在外圈的外部的圆周面上。
发明内容
本发明所要解决的技术问题在于提供一种车轮轴承单元，该车轮轴承单元能够确保对轴承进行更可靠的密封。
根据本发明，所述技术问题通过一种车轮轴承单元来解决，所述车轮轴承单元具有轮毂，其中轮毂在其一端具有集成地构成的车轮法兰和能够与轮毂一起转动的内圈，其中内圈通过滚动铆钉接合件固定在轮毂上，以便使滚动体列抵靠地预张紧在外圈上，所述车轮轴承单元还具有编码器(Encoder)，所述编码器设置在内圈上并径向地朝外圈延伸，并且所述车轮轴承单元还具有保护盖装置，所述保护盖装置被固定在外圈上，以便将在外圈和轮毂之间构成的环状开口闭锁和密封，其中，所述保护盖装置通过圆柱形的装配部段被压入外圈的圆柱形的挤压部段中，并且屏蔽部段从所述圆柱形的部段径向方向向内延伸，并且设有底部部段，所述底部部段与屏蔽部段邻接，以便覆盖轮毂的内侧端部，其中，在所述圆柱形的部段的背离外圈的圆周面上设置密封件，其中，所述密封件被这样构造，使密封件的部分在轴向方向上从所述装配部段凸出，以便形成密封唇，所述密封唇轴向地移至外圈的部段上，以便密封地贴靠在所述部段上。
在根据本发明的车轮轴承单元中，为了密封在外圈和轮毂之间的环状开口设置保护盖装置。该保护盖装置通过圆柱形的装配部段被压入外圈中。为了改善保护盖装置的密封作用，在装配部段的背离外圈的圆周面上设置密封件。在这种情况下，该密封件被这样构造，使其在轴向方向上从装配部段凸出并由此构成了静态的密封唇。在按压装配部段时，密封唇轴向地在外圈的部段上或沿着外圈的部段移动，以便密封地贴靠在外圈的部段上。密封件的设在装配部段上的区域此时在按压保护盖装置时保持不被触碰，也就是说，没有弹性变形。这种构造能够更可靠地密封车轮轴承单元并防止雨水或灰尘由外部浸入轴承内、以及防止在轴承内部的润滑脂泄露。相比现有技术的另外的优点是，通过根据本发明地对密封件的安置，使得在按压保护盖装置时密封件在装配部段和外圈之间不会被挤压，由此密封件也不会受损坏。这样总体上改善密封并增加了使用寿命。
优选的是，外圈的被密封件贴靠上的部段是倾斜的。该部段与外圈的按压装配部段的圆柱形的部段贴靠。通过倾斜的部段能够实现，密封唇沿着外圈移动并能够密封地贴靠在外圈上。优选地，该部段被这样构造，在一个加工过程中制成或能够经过磨削工艺处理单个部段或者整个外圈。替选地，所述部段还可以具有半径、梯部或类似的部分。
根据本发明的设计方案，保护盖装置由非铁磁材料制成。由此能够避免对磁通量的负面影响。
有利地，密封件由弹性体构成并在保护盖装置的装配部段上被硫化。由此保证密封件保持在固定的位置中。
根据本发明的设计方案，所述密封件沿着保护盖装置延伸。这意味着，除了装配部段，密封件也沿着保护盖装置的其他部段被硫化。这样具有的优点是，非铁磁金属材料还可以用于构成保护盖装置，而不会对磁通量产生影响。
根据本发明的备选的设计方案，底部部段通过圆柱形部段与屏蔽部段邻接。替选地，该圆柱形部段也可被设计为具有半径或斜的、倾斜的或梯形的。由此，保护盖装置能够设计为节省空间的并且能够与车轮轴承单元相匹配。
根据本发明的设计方案，保护盖装置通过所述圆柱形的装配部段被压在外圈的内圆周上。替选地，保护盖装置通过所述圆柱形的部段被压在外圈的外圆周上。根据需求或现有的结构空间，保护盖装置被压在外圈的内圆周或外圆周上。
有利地，保护盖装置是壳状的且通过压模构成。通过这样设计保护盖装置可以提高刚性并防止出现碎石等以导致变形。
根据本发明的设计方案，设置转速传感器来检测轮毂的转速度，其中所述转速传感器和编码器在轴向方向上通过所述屏蔽部段以预定的空隙彼此对置。
附图说明
下面基于三个附图示出本发明的两个实施例。附图为：
图1是剖切根据本发明的第一实施方式的车轮轴承单元的纵向剖视图，
图2是图1中所示的单元1的放大视图，
图3是剖切根据本发明的第二实施方式的车轮轴承单元的纵向剖视图，以及
图4是根据第三实施方式的压入的保护盖的放大视图。
具体实施方式
图1示出剖切根据第一实施方式的车轮轴承单元1，该车轮轴承单元配属于未示出的车辆车轮。车轮轴承单元1包括轮毂2，该轮毂在它的端部具有一体式构成的径向定向的车轮法兰3。车轮用轴承组件还具有两个轴向间隔的滚动体列4、5，滚动体列的滚动体在外侧在外圈6中被导引。滚动体列4的滚动体在内侧直接在轮毂2的导轨或滚动面中被导引，并且滚动体列5的滚动体在内侧在固定在轮毂2上的内圈7中被导引。
内圈7通过滚动铆钉接合件8轴向地固定在轮毂2上，由此使滚动体列5抵靠地预张紧在外圈6上。
如还可从图1中观察到，编码器9被安置在内圈7的外周上。编码器9设置在支撑件10上，通过该支撑件编码器9与内圈7的外周连接。编码器9由用磁性颗粒填充的弹性体材料构成，该编码器9通过硫化与支撑件10集成地连接。除了弹性体材料之外，编码器9也可以由塑料或硬橡胶制成。
保护盖装置11被设置用于密封外圈6与轮毂2之间的开口，保护盖装置由非铁磁材料通过冲压成型制成。保护盖装置11通过圆柱形的装配部段12被按压在挤压部段13(外圈6的内周)上。屏蔽部段14在径向方向R1上向内邻接圆柱形的部段12。底部部段16通过圆柱形的部段15与屏蔽部段14邻接。
图2示出图1中所示的单元1的放大视图，即保护盖装置11的放大图示。如图所示，装配部段12具有密封件17。密封件17设置在装配部段12的背对外圈6的圆周面18上。密封件17被设计为经硫化的弹性体。
密封件17还被这样设计，使密封件的一部分在轴向方向R2上从装配部段12凸出，以便形成密封唇19。在将装配部段12压入圆柱形的部段13内时，只有密封唇19的区域轴向地移至外圈6的部段20，以便密封地贴靠在部段20上。在这种情况下，密封件17的在装配部段12上经硫化的区域保持不被触碰，即，没有弹性变形。
外圈6的部段20(密封唇19贴靠在该部段20上)是倾斜的并且直接与挤压部段13邻接。
图3和图4示出根据第二和第三实施方式的保护盖装置11。相应的部件以相同的附图标记标识。因此，下面的描述主要关于区别特征。
在图3中示出的保护盖装置11与在图1和图2中描述的保护盖装置11相符。除了设置在装配部段12上的密封件17，密封件21也沿保护盖装置11的整个端面22延伸。端侧22是背离车轮轴承单元1的一侧。密封件21还具有多个密封唇23。
图4示出压入的保护罩11的放大视图。基本上，该车轮轴承单元1与在图3中示出的车轮轴承单元1相符。保护盖装置11的屏蔽部段14具有多个沿圆周分布的留空或凹口24。该凹口24可被设计为例如长孔。此外，凹口24被密封件21覆盖或由密封件21封闭。备选地，还可行的是，将凹口24被密封件21覆盖的区域留空。
