Description

车轮用的轮毂轴承组件
技术领域
本发明涉及车轮(vehicle wheel)用的轮毂轴承组件。
背景技术
已知的轮毂轴承组件具有转动轴线并且包括：
-轴承外圈，其由与所述转动轴线同轴的圆柱外表面限定并具有遍及该圆柱外表面地形成的成形槽；
-轴承内圈，其与外圈一起限定了中间空间，并且设置有与所述转动轴线相横向的凸缘；和
-密封装置，其介于外圈与内圈之间，以防止任何杂质通过所述中间空间进入所述轮毂轴承组件，并且进而包括：保护盖，所述保护盖安装在凸缘上以与内圈一起转动，并且保护盖围绕外圈的圆柱外表面延伸以使中间空间与该中间空间的外部相隔离。
在上述类型的轮毂轴承组件中，盖终止于在成形槽处面对外圈的环形出口，并且，尽管盖的这种特定构造和成形孔的形状构造(shaping)与环形出口的位置的相互作用，但是已经发现，在非常苛刻的(demanding)使用条件下或者当存在大量杂质时，盖的密封作用不如预期那样可靠，这可能是因为在某些情况下定位盖时的微小误差随后损害(compromised)了环形出口的位置与成形槽的位置的必要的组合效果。
发明内容
本发明的目的是提供一种车轮用的轮毂轴承组件，这种轮毂轴承组件在具有有限的重量以便能够在与二氧化碳排放有关的日益严格的规定的背景下销售的同时，不仅允许增大了密封能力，而且还确保了所有组成部件的正确定位，而无需在生产期间进行进一步的检查(而这种进一步的检查通常对周转时间(cycle times)具有延迟效应(retardingeffect)，并且还会增加生产成本)。
根据本发明，提供了一种车轮用的轮毂轴承组件，其具有在所附权利要求中叙述的特征。
附图说明
现在将参照附图来说明本发明，附图示出了本发明的实施方式的非限制性示例，在附图中：
-图1是根据本创新制造的车轮用的轮毂轴承组件的第一优选实施方式的截面图；
-图2是图1的轮毂和车轮组件的细节的放大截面图；以及
-图3是图1的轮毂和车轮组件的第二优选实施方式的细节的放大截面图。
具体实施方式
参照图1，数字10表示轮毂轴承组件的整体，该轮毂轴承组件具有转动轴线A并且包括：轴承外圈20；轴承内圈30，其与外圈20一起限定了中间空间(interspace)40；和多个滚动体50，其介于外圈20与内圈30之间，以能够使外圈20相对于内圈30转动。
出于(在内圈上)安装(已知且未示出的)车轮的目的，内圈30设置有与转动轴线A相横向的凸缘31，并且在径向上朝向外侧由环形装配表面(fitting surface)32限定。
外圈20可以联接于车辆的固定元件，例如悬架支柱(suspension strut)，并由前环形表面21和外表面22限定，所述前环形表面21与凸缘31一起限定了中间空间40的进口(inlet)41，所述外表面22绕着转动轴线A分布并且具有遍及(through)外表面22地形成的成形槽(shaped groove)60。
还如图2所示，槽60在外表面22上限定了安装表面23，安装表面23优选从环形表面21开始以与轴线A成α角度倾斜，该角度优选为锐角(acute)并且为等于0度以上(or more)，并且(安装表面23)在轴向上在一侧由环形表面21界定，而在轴向相对侧由成形槽60的接合边缘61界定。特别地，成形槽60具有两个斜面(ramps)62和63，这两个斜面62和63相对于转动轴线A而言具有彼此不同的倾斜度，并且这两个斜面62和63在槽60的底部彼此结合，斜面62具有比斜面63大的倾斜度，并且在径向上朝向外侧由边缘61界定。
如上所述，轮毂轴承组件10可以被(设置)介于车辆的固定元件(例如悬架支柱)与车辆的车轮之间，因此必须在受液体和灰尘两者的存在而高度污染的环境中运行(operation)：为了保持轮毂轴承组件10的技术特性(technical characteristics)和正确运行，轮毂轴承组件10包括密封装置80，该密封装置80被介于外圈20与内圈30之间，以防止任何杂质(impurities)通过中间空间40进入轮毂轴承组件10内，并且(密封装置80)进而包括：保护盖81，保护盖81安装在凸缘31上以与内圈30一起转动，并且围绕外圈20的外表面22延伸以使中间空间40与该中间空间40的外部相隔离(close off)，也就是说，与轮毂轴承组件10的外部(相隔离)。
保护盖81包括：圆柱壁82，其装配于凸缘31的圆柱装配表面32；侧向壁(lateralwall)83，其与转动轴线A相横向并且在轴向上面对凸缘31；和末端壁(terminal wall)84，其相对于转动轴线A倾斜并朝向成形槽60(定向)。壁82与侧向壁83是(相)横向的并且彼此成一体，而末端壁84与侧向壁83在中间介入有另外的圆柱壁85的情况下成一体，所述另外的圆柱壁85与轴线A同轴地延伸并从侧向壁83横向地远离凸缘31。圆柱壁85是可选的(optional)壁，这是因为末端壁84可以直接从侧向壁83朝向外表面22延伸，但是圆柱壁85能够使末端壁84的轴向位置与壁82的轴向尺寸无关(independent of)，使得保护盖81的设计更加灵活(flexible)。
在凸缘31的相对侧，末端壁84具有倾斜(度)与斜面62的倾斜(度)相反的(opposite)外保护表面86，并且(末端壁84)在径向上朝向内侧由末端自由边缘(freeterminal edge)87限定，所述末端自由边缘87位于成形槽60内的斜面62的位置处并与斜面62一起限定了连接到中间空间40的环形出口(outlet)42。
环形出口42的形状和尺寸、外保护表面86的倾斜度、斜面62自身所考虑的倾斜度和斜面62相对于表面86的倾斜度(而言)的倾斜度、以及环形出口42在成形槽60内的定位(positioning)都是共同限定了密封装置80的密封能力的特征：特别地，斜面62与表面86的相反的倾斜度使得污染物特别难以通过环形出口42进入和上升(rise)，而斜面63与表面86的相似的倾斜度趋于逐渐减小出口42前面的空间，因而与壁84的转动相结合，在污染物(尤其是液体性质的污染物)中产生湍流运动(turbulent motion)，该湍流运动在轮毂轴承组件10的使用期间在出口42处出现。由于环形出口42被定位在槽60内并且(被定位)在斜面62附近，因此出口42起到真正的迷宫密封(true labyrinth seal)的作用。
此外，在液体污染物仍成功渗透到中间空间40内的这种不太可能的情况(event)下，成形槽60起到沟槽(gutter)的作用并且促进这些污染物朝向中间空间40的外部向回流出，并且在该流出操作中受到多个孔90的帮助，所述多个孔90大致在侧向壁83的附近贯通圆柱壁82地形成，并且绕着轴线A均匀分布。
从以上说明可以看出，上述车轮用的轮毂轴承组件10具有优异的密封和防止外部污染物的特性，并提供了这样一组布置，使得能够在轮毂轴承组件10及其滚动体50的密封和保护方面实现高效率。
此外，为了在轮毂轴承组件10的密封和保护方面提供这种高效率，末端自由边缘87的直径小于成形槽60的接合边缘61的内径，因此在轮毂轴承组件10的组装期间，末端自由边缘87被卡接配合(snap-fitted)于成形槽60中。特别地，外圈20和内圈30与已经被装配于凸缘31的盖81的轴向运动使得末端自由边缘87与安装表面23接合，并且还使得末端自由边缘87在表面23上逐渐滑动，直到其经过(pass over)接合边缘61(为止)。这种通过盖81的构造(其使得末端壁84自由弯曲并且末端边缘87精确地自由跟随安装表面23的)而被另外促进的类型的安装始终提供了末端自由边缘87在成形槽60内的正确定位，换言之，环形出口42在靠近槽60的斜面62的位置的正确定位。接合边缘61的存在及其与末端边缘87的相互作用是本发明的必要特征(essential characteristics)之一，对于(As is)末端自由边缘87与斜面62的接近度(closeness)，尽管斜面62的形状不限于是已在图2中说明和示出的那样，但是优选地，作为一种选择，斜面62的形状还可以被构造成如图3所示，在图3中，槽60的斜面62由与轴线A相横向的表面形成，而斜面63完全不存在并且完全合并于(incorporatedinto)表面22中，或者作为一种选择，(斜面63)由与斜面62大致正交的锥形表面形成，该锥形表面逐渐地并入于(merges into)表面22。
除了如上所述的本发明的实施方式以外，应当理解，存在许多其它变型。还应当理解，所述实施方式仅仅是示例性的，并且不限制本发明的范围、应用或可能的构造。而相反，尽管以上说明能够使本领域技术人员以至少一个示例性构造应用本发明，但是应当理解，可以在不脱离(如在所附权利要求中限定的、在字面上和/或根据其法律等同物解释的)本发明的范围的情况下，设计出所描述的组成部件的许多变型。
