Description

低摩擦密封组件的联接***和设有该密封组件的轮毂单元
技术领域
本发明涉及一种用于将密封组件联接到轮毂单元的***，此外还涉及一种配备有所述联接***的轮毂单元。
背景技术
已知类型的轮毂单元通常包括：静止的外圈；带有凸缘的内(轮)毂，所述内毂在使用时转动且设置有用于在使用时支撑车轮的凸缘，所述轮毂单元配备有用于将密封组件联接到轮毂单元的联接***，其中所述密封组件由所谓的“盒式(cassette)”密封件组成，包括彼此面对安装的第一环形遮蔽件和第二环形遮蔽件，第一环形遮蔽件和第二环形遮蔽件分别位于外圈和带有凸缘的毂的干涉配合面上，以彼此界定了环形室，在该环形室内，配置了由一体固定到遮蔽件中的一者(通常为在使用时用于保持静止的遮蔽件)的环形密封件承载的一系列密封唇。
然而，已发现的是，由于凸缘的挠曲(deflection)，即由于在车辆转弯时(goround bends)凸缘因车轮而经受的变形，因此安装在带有凸缘的(轮)毂上(因此被靠近车轮支撑凸缘设置)的遮蔽件趋于在使用时相对于带有凸缘的毂自身而言沿轴向移动。
该缺点一方面增大了影响密封组件的摩擦，这是由于未刮擦(因此未产生摩擦)的密封唇可能变得刮擦(因此产生摩擦)，且刮擦的任意密封唇增大了它们的干涉，因此增大了产生的摩擦。另一方面，在相对大的运动的情况下，可能在转动的遮蔽件与静止的外圈之间引起干涉，同时产生非常高的摩擦，这可能对密封组件造成损伤，甚至在最严重的情况下，可能对轮毂组件自身造成损伤。
发明内容
本发明的目的在于提供一种用于将密封组件联接到轮毂单元的***，其没有上述缺点，该***还具有低成本和高度易制造性、在保护旋转体方面的高效率、轴向和径向上的小尺寸以及低摩擦。
因此基于本发明，提供了一种具有所附技术方案中提到的特征的用于将密封组件联接到轮毂单元的***。
此外，还提供了如在技术方案5中限定的轮毂单元。
附图说明
现将参照附图说明本发明，附图示出了实施方式的非限制性示例，在附图中：
图1在径向上示意性地示出根据本发明制成的且包含根据本发明的联接***的轮毂单元的出于简化目的而去除了部件的纵向立视图；以及
图2在径向上示意性地示出图1的联接***的细节。
具体实施方式
参照图1，标号1表示被设计成安装在车辆的轮毂单元2上的低摩擦密封组件，在使用时车辆的轮毂单元2的密封组件1形成一体部件。
轮毂单元2包括：外圈3，其在使用时是静止的；内圈4，其在使用时绕着轴线A转动，所述轴线A也是内圈3和外圈4这两者对称轴线以及密封组件1的对称轴线；和滚动体6的至少一个冠部，该滚动体6介于彼此同轴的外圈3与内圈4之间；内圈4在与外圈3相对的一侧配置有凸缘8，并在使用时用于承载车轮。
密封组件1能够***到在转动内圈4与外圈3之间界定的环形空间7内，且更一般地说，密封组件1能够***到(形成轮毂单元2的一部分或与轮毂单元2成一体的)任意已知类型的通用滚动轴承的彼此同轴的转动元件4和静止元件3之间的环形空间7内。
密封组件1介于圈3与圈4之间、***到环形空间7内，以保护配置在静止元件3与转动元件4之间的滚动体6，且(密封组件1)包括：第一环形遮蔽件(/防护件)(shield)10，其由金属片(metal sheet)(优选为不锈钢)通过剪切和冲压形成；第二环形遮蔽件11，其也由金属片(优选为不锈钢)通过剪切和冲压形成，该第二环形遮蔽件11配置成面对遮蔽件10；和环形密封件9，其由一种或多种弹性体材料制成、由遮蔽件11一体地承载并配置有多个密封唇12、13、14，该多个密封唇12、13、14与遮蔽件10协作(cooperate)以对环形空间7提供朝向滚动体6的防流体密封。
遮蔽件10设置有：套筒部15，其由管状转动固体(tubular rotation solid)限定，在使用时与转动元件4成一体；凸缘部16，(在非限制示例中被示出位于与轴线A相对的一侧)从套筒部15沿径向且悬伸地(overhangingly)延伸，因此径向向外延伸。凸缘部16按照其顺序包括：环形部18，其配置为轴向地靠近凸缘8的表面8a；以及锥形部19，其介于环形部18与套筒部15之间。在特定的情况下，凸缘部16(或者更好是环形部18)沿径向延伸出环形空间7外，相对于圈3的径向外侧面23径向且悬伸地(延伸)，结果圈3因此面对凸缘部16的径向外侧部。此外，环形部18在轴向上由与轴线A横向的表面18a界定且被配置成与表面8a接触。
根据本发明的一方面，还如图2所示，出于避免在使用时遮蔽件10朝向圈3和相对的遮蔽件11移动的可能性的目的，根据本发明的密封组件1包括至少一个遮蔽件，在特定的情况下，遮蔽件10具有如下这样的套筒部15：该套筒部15在轴向上朝向滚动体6的冠部由与轴线A横向的环形面20界定，并且朝向内圈4由(面向由圈4限定的转动元件的)侧向安装面21界定，该横向安装面21具有沿着轴线A具有恒定尺寸的直径φm的筒状几何形状。
根据本发明的另一方面，至少遮蔽件10由冲压和剪切的金属片制成，使得套筒部15能够弹性变形。
借助于赋予套筒部15的创新形状，对于一般的密封组件而言，根据本发明建立了完整的联接***(coupling system)，在对于密封组件1的遮蔽件10而言具有环形转动元件的特定情况下，在(具有)轴承内圈4的特定情况下，***整体由24所示。
联接***24包括密封组件1的第一环形遮蔽件10以及特别是在使用时用于与环形转动元件4(在环形转动元件4的组装座中以及自身的组装座中)联接成一体的套筒部15，其中套筒部15朝向环形转动元件4由具有恒定直径φm的侧向安装面21界定；其中，用于将遮蔽件10组装到环形转动元件4上的组装座由浅筒状凹部25(图2)构成，所述浅筒状凹部25在径向上由面向径向外侧且具有恒定外径φb的筒状底面26界定。在凸缘8所在侧，浅筒状凹部25在轴向上由在表面8a和底面26之间的环形连接面(toroidal connecting surface)33界定，而在滚动体6的冠部所在侧，(浅筒状凹部25)由轴向肩部27界定。
特别地，由浅凹部25限定的组装座(/组装座部)(assembly seat)形成在转动元件(即在所示的示例中为内圈4)的筒状侧向压配面28上，通常在使用时用于接纳(receive)遮蔽件10。
应当注意的是，出于改善将遮蔽件10轴向锁定到带有凸缘的内圈4的压配面28上的目的，代替的是，采用筒状干涉部15与组装座的组合(组装座自身具有类似于表面26的筒状压配面，如将看到的，在由图1中的箭头表示的在使用时将遮蔽件10***环形元件4的***方向D的相对侧，该筒状压配面在轴向上由环形肩部27界定)，出人意料地呈现明确的(definitively)稳定。
因此，根据本发明的完整联接或干涉配合***24包括：第一遮蔽件10的第一套筒部15，该第一套筒部15作为具有筒状形状的管状转动固体限定了用于将遮蔽件10组装到环形元件4的干涉配合部；以及(包括)浅环形凹部25的底(表)面26。
此外，根据本发明的另一方面，由环形凸台或凸起29(所述环形凸台或凸起29朝向环形转动元件4的自由前边缘(free frontal rim)30界定了浅凹部25)限定的轴向肩部27还形成了根据本发明的完整联接或键入***24的一部分；在该环形转动元件由轮毂单元2的内圈4定义的所示特定情况下，自由前边缘30界定了设置在凸缘8侧的、滚动体6用的滚道(rolling track)31。
环形转动元件的环形凸部(relief)29在径向截面(图2)中具有朝向浅凹部25由坡面32限定的圆形轮廓，该坡面32在安装点90处与筒状底面接合，使得套筒部15的自由筒状端部22通过滑入配合(/卡入配合)(snap fit)紧密接合于坡面32自身，且使得安装点90距表面8a的轴向距离具有与环形遮蔽件10的轴向上的延伸长度相同的轴向长度，(所述轴向距离)特别为表面18a与表面20之间的轴向距离。
根据本发明，环形转动元件或内圈4的筒状侧向面28的直径大致等于或稍小于环形凸部29在其最大径向高度处的外径φr；按照组合的方式，套筒式干涉配合部15的朝向环形转动元件4的侧向安装面21的直径φm使得在套筒式干涉配合部15与由环形凸部29和浅凹部25限定的干涉配合座之间形成有力的或稍微有力的干涉联接，使得(从套筒式干涉配合部15与凸部29的首次联接起就开始有的)该有力的或稍微有力的联接启动，且随着套筒式干涉配合部15沿着浅凹部25沿方向D***而保持大致恒定，在同时或大致同时进行如下动作时的时刻使套筒式干涉配合部15自身稳定：表面18a与表面8a接触，且端部22在“越过”凸部或凸起29之后、特别是在接近安装点90被承载之后、即超过构成凸部29的圆形轮廓的“缓坡”且形成轴向肩部27的表面32(之后)，通过卡入配合联接到浅凹部25内。
按照这种方式，一旦套筒式干涉配合部15完全***由浅筒状凹部25形成的组装座内，侧向安装面21配置为以干涉的方式直接接触在底面26上，遮蔽件10被在方向D和在与方向D相反的方向上轴向锁定，遮蔽件10的轴向位置被确保且不可变(immutable)，包括(遮蔽件10的轴向位置)在使用时相对于圈3和圈4两者、尤其是相对于与遮蔽件11成一体的环形密封件9而言(被确保且不可变)，即使在凸缘有任何挠曲(即，在车辆转弯时凸缘因车轮而经受的变形)之后，密封唇12、13、14的相对位置也将不会有改变。
根据本发明，归因于联接***24，获得了与上述轮毂单元类似的轮毂单元2，其中遮蔽件10具有筒状干涉配合套筒状部15，该筒状干涉配合套筒状部15在生产中容易实现且在组装阶段具有“越过”凸部或凸起29的足够弹性，且弹性恢复成与内圈4的筒状面28联接，该筒状面28被包括在凸缘8和与凸缘8相邻的滚道31之间，此外，优选与该特征组合，内圈4在凸缘8与内圈4的界定了滚动体6的滚道31的自由前边缘30之间具有筒状侧向面28，该筒状侧向面28设置有第一遮蔽件10的套筒式干涉配合部15用的组装座，该组装座由浅环形凹部25限定(所述浅环形凹部25由筒状底面26和配置在与第一凸缘部16相对的一侧的轴向肩部27界定，并且(所述浅环形凹部25)限定了用于安装遮蔽件10的确定轴向空间)，遮蔽件10自身一旦组装在该组装座内，就不再能够移动。
应当理解的是，本发明不限于这里描述和图示的实施方式(这些实施方式将被看作实现低摩擦密封组件的示例)，然而这些实施方式能够在部件的形式和设置、构造细节和组装方面做进一步的变型。
