Description

具有用于编码器的保护壳体的轴承组件
技术领域
本发明涉及一种具有用于磁性编码器的保护壳体的轴承组件。
背景技术
为了检测轴承组件的转动座圈和固定座圈之间的转动的相对速度，一般地使用检测装置，这种检测装置包括安装在转动轴承座圈上的磁性编码器和装配在固定部件上的以预设距离面对编码器的位置处的传感器。由于编码器的转动而由传感器产生的电信号被传送至处理单元，其提供关于转动部件的转动(转动速度、角度位置等)的信息。采用轮毂轴承单元，安装在车辆板上的处理单元提供关于车轮转动的信息。
US6939050公开一种安装在外部固定轴承座圈上的包括非铁磁性材料的壳体，用于保护该编码器并且从轴向内侧(或内板侧)密封该轴承。该编码器与限制该编码器的径向尺寸的密封装置相关联。
发明内容
本发明的目的是增加由编码器产生的磁场的强度，使得相关联的传感器能够拾取足够强的磁性脉冲，虽然该壳体夹置在编码器与传感器之间。也需要更自由地选择传感器所要安装的位置，而不需要以相等的距离将其精确地定位在编码器的径向延伸部分的磁场最大的中间的前部。
通过具有所附权利要求限定的特征的轴承组件，实现根据本发明的上述和其他目的和优势，这将在下文中得到更好的理解。
附图说明
现在将参照附图说明本发明的一些优选但非限制性实施例，其中：
图1是根据本发明第一实施例的轮毂轴承组件的轴向剖视图；
图2是图1的详细内容的放大视图；
图3是根据本发明第二实施例的轮毂轴承组件的轴向剖视图；
图4是类似于本发明的第三实施例的详细内容的图2的视图；以及
图5、6、7和8A-8C是本发明的另一实施例的轴向横截面剖视图。
具体实施方式
首先参照图1，轮毂轴承组件总体标示为10，外部固定轴承座圈11可固定至电动车辆的悬挂标准件，径向内部可转动轮毂12形成径向凸缘13以固紧至车辆的车轮(未示出)。内部轴承座圈15通过滚压其边缘14而固定在轮毂12的轴向内侧或者内板侧上。外座圈11形成用于两组滚动体18、19(在该实例中为滚珠)的径向外座圈16、17，而径向内座圈20和21分别通过轮毂11和内座圈15形成。
虽然传统密封装置22设置在该组件的轴向外侧(外板侧)上从而密封外座圈11和轮毂12之间的环形空间，但是这种类型的装置没有设置在该组件的内板侧上。在这一侧上，位于轴承座圈11与15之间的环形间隙是采用环形盘形式的磁性编码器23，固定至具有L形横截面并且安装在内轴承座圈15上的支承环24。如图2更清楚地示出，支承环24具有强迫地固定至内座圈15的外圆柱表面26上的圆柱部分25，以及从圆柱部分25的轴向内端沿径向向外方向延伸的凸缘27。该环形编码器23装配在凸缘27的轴向内侧28上，并且径向地向上延伸至外座圈11的内部圆柱表面29附近。外座圈的内表面29与编码器的外周边缘之间的径向间隙G1可保持为大约0.2mm的窄度从而避免旋转编码器23与非旋转外座圈11之间的任何接触，同样地，该编码器安装有一些部件(defect)和/或在高外部载荷的动作下，尤其是趋于沿轴向平面使轴承偏转的侧向载荷。
包括非铁磁性材料(例如，铝、铜等)的保护壳体30使用在轮毂轴承组件的内板侧上，从而保护该编码器并且密封该轴承，在壳体30与编码器的轴向内侧之间留下最小的轴向间隙G2。
在附图所示的优选实施例中，壳体30具有面对内板侧的径向外周部分31和轴向圆柱边缘33，该径向外周部分31轴向地邻靠外座圈11的侧表面32，该轴向圆柱边缘33被强迫地装配在轴承外座圈的外圆柱表面34。
由于上述结构，根据本发明，该编码器的径向尺寸增加，由此实际地利用轴承座圈11与15之间的所有空间。因此，产生比较强的磁场。这也允许设计师在设定传感器(未示出)的位置时具有更大的自由度，其并不是必要地在其径向延伸部分的一半精确地面对该编码器，此处的磁场的强度是最大的，相对于编码器具有相同的距离。由于本发明，该传感器根据所需和可用的空间也可代替地定位在径向外部位置或内部位置，如图2中的P所示。采用这种方式，即使该传感器可以不精确地定位在编码器中间部分的前部，其仍然能够拾取磁性信号，该信号足够强以产生清楚地表示轮毂旋转参数的电信号。
采用这里所述的通用设计的轮毂轴承单元，侧表面32传统上以高精确度机制，因为其用作将编码器装配在轮毂轴承单元的参考表面，如上所述，用于确定壳体30的正确轴向位置。采用这种方式，可实现精确尺寸的最小轴向间隙G2，允许减小编码器与传感器(未示出)之间的整体距离。因为，密封装置不再必须装配在外座圈的内圆柱表面29，可实现机制该表面，这是有利的，因为其消除了传统所需的步骤。而且，在根据本发明的轮毂轴承组件中，相对于现有技术，也消除了装配在该组件的内板侧上的密封装置。这减小了该组件的滚动摩擦并且降低了密封装置的制造和组装成本。最后，内板侧上的外轴承座圈11和内轴承座圈15的轴向尺寸可被减小，因为其不必要容纳密封装置，而只是占据相当有限的轴向空间的编码器23。这有助于使得该组件更轻并且轴向方向紧凑。作为一项备选实施例，以相同的轴向大小，两组滚动体可以进一步地分离开，由此获得该组件作为整体的在轴向平面弯折方面的更大刚性。这可防止编码器的周向边缘与外座圈的内圆柱表面29之间的任何接触。
在图3所示的实施例中，壳体30形成夹置在轴承外座圈11与悬挂标准件36之间的径向外部延伸件或凸缘35。该凸缘35覆盖外座圈凸缘11a的内板侧，并且用于防止该悬挂接触该轴承，因此避免在由不同金属制成的两个主体之间的交接处出现电解腐蚀，否则会使得该轴承单元难于从该悬挂移除。
应该理解，本发明并不局限于这里所述和所示的被认为是该组件的实例的实施例；相反地，本领域技术人员清楚可知，本发明可以在部件的形状、布置结构、构造和功能细节方面进行改进。作为实例，该保护性壳体可以不具有周向边缘33，如图4的实施例所示。这里，壳体30直接地装配在外座圈11的侧表面32上，例如采用铜焊或软焊或焊接或胶粘的方式，并不需要对外轴承座圈的外圆柱表面34进行任何的机制以将壳体装配至该轴承，因此不会形成图2所示的步骤。
此外，本发明也可应用于不同于图1和3所示的不同的轴承组件。例如，如图5的实施例所示，本发明可应用于需要旋转反馈的几乎任何旋转部件的轴承组件(例如，角度位置、旋转速度等)。图5示出装配至具有单组滚动体的轴承单元的壳体30，在该实例中是深槽滚珠轴承单元。在图6的变化实施例中，周向边缘33延伸，形成外圆柱表面34上的套筒，夹置在轴承外座圈11与轴承壳体(未示出)之间。在图7的实例中，套筒33在轴承的侧部上伸长，相反于具有编码器的侧部，并且形成径向外凸缘38，该凸缘提供一装置，用于将轴承单元安装至诸如墙壁的支承件S，或者该壳体以任何公知方式固紧所至的外壳。作为备选方案或者除了任何上述将壳体固紧至装配有编码器的轴承侧部的装置，该壳体可固紧至相对侧上的轴承。在图8A、8B和8C所示的实施例中，壳体30借助径向向内伸出的部分37而固紧至该轴承，该向内伸出部分采用周向的相邻凸片的形式，延伸自套筒33并且相对于或朝向轴承的与装配有编码器的侧部相对的侧部弯折。该凸片37的径向范围使得该轴承的那侧上的密封动作具有不同的程度。
