具体实施方式
本文中描述了本公开的各实施方式。应该意识到的是，出现在不同附图视图中的同样的附图标记标识相同或功能相似的结构元件。还要理解的是，所公开的各实施方式仅是示例，并且其他实施方式可以采取各种形式和替代性形式。这些图不一定是按比例的；为了示出特定部件的细节，一些特征可以被放大或最小化。因此，本文中所公开的具体结构和功能细节不应被解释为限制性的，而是仅作为用于教示本领域技术人员以各种方式采用各实施方式的代表性基础。如本领域普通技术人员将理解的，参照附图中的任何一个附图所图示和描述的各种特征可以与在一个或更多个其他附图中所图示的特征组合，以产生未明确图示或描述的实施方式。所图示的特征的组合为典型的应用提供了代表性实施方式。然而，对于特定应用或实现方式，可能期望与本公开的教示相一致的特征的各种组合和改型。
本文中所使用的术语仅为了描述特定方面的目的，并且不意在限制本公开的范围。除非以其他方式限定，否则本文中所使用的所有技术和科学术语具有与本公开所属技术领域中的普通技术人员中的一个普通技术人员通常所理解的含义相同的含义。尽管可以在本公开的实践或测试中使用类似于或等同于本文中所描述的那些方法、装置或材料的任何方法、装置或材料，但是现在描述以下示例方法、装置和材料。
参照图1至图2进行以下描述。图1图示了根据本公开的示例方面的混合动力模块100的上半部横截面图。图2图示了图1的混合动力模块100的一部分的详细视图。用于机动车辆(未示出)的混合动力模块100包括具有定子104和的转子106电动马达102。定子104固定至壳体并且接收线圈108中的电能以使安装在转子106的外周表面上的转子区段109旋转。转子106与内燃发动机(未示出)协同工作以推进机动车辆。也就是说，转子106包括变矩器110，该变矩器与多级车辆变速器驱动地接合并且将扭矩传输至本领域已知的车辆传动系。
电动马达转子106包括转子承载件112、活塞承载件114和渐缩式卡环116。转子承载件包括：内周表面118，该内周表面具有用于接纳多个离合器片122的内花键120；内周表面124，该内周表面位于内周表面118的径向外侧；径向壁126，该径向壁连接表面118和124；以及凹槽128，该凹槽具有锥形壁130。活塞承载件114包括安装在凹槽与径向壁之间的径向外环132。渐缩式卡环116安装在凹槽中并且将活塞承载件推动成与径向壁接触。内周表面124包括键134并且径向外环132包括与键驱动地接合的槽136。
电动马达转子还包括渐缩式螺母138。活塞承载件114包括螺纹部分140，渐缩式螺母138安装在螺纹部分上，并且渐缩式螺母包括锥形表面142，该锥形表面将渐缩式卡环径向向外推动到凹槽中。也就是说，当螺母被拧紧到螺纹部分上时，锥形表面在渐缩式卡环下方延伸并且使卡环径向扩张。当卡环扩张时，卡环上的渐缩部被迫抵靠凹槽128的锥形壁130，从而将卡环远离锥形壁并且朝向活塞承载件114推动。因此，当螺母138被拧紧时，活塞承载件外环132紧密压靠径向壁126。如下所述，消除转子承载件112与活塞承载件114之间的轴向间隙减小了离合器分离公差。
电动马达转子106包括离合器片122和活塞144。离合器片122与内花键120驱动地接合。活塞144由安装在活塞144中的径向外密封件146和安装在活塞承载件114中的径向内密封件148密封至活塞承载件。活塞144用于轴向按压多个离合器片以传输扭矩。也就是说，液压压力通过隔板152中的通道150和毂156中的通道154引入并且进入液压室158。室158中的高压将活塞144朝向离合器片122推动成接合离合器并且将扭矩从离合器内承载件160传输至转子承载件112。
电动马达转子106包括垫片162。活塞144包括用于按压离合器片122的环形突出部164，并且垫片162在轴向上设置在环形突出部与多个离合器片之间。选择垫片162的厚度以调节离合器的分离。也就是说，为了在离合器断开接合时更好地控制活塞与离合器片之间的距离，可以测量用于每个转子承载件组件的部件并且可以选择特定厚度的垫片以减小离合器断开接合时的分离公差。减小的公差有助于改进离合器接合并且减小离合器断开接合时的阻力。
电动马达转子106包括如上所述的密封至活塞承载件114的活塞144、由密封件168密封至活塞144的平衡坝166以及卡环170。活塞承载件114包括凹槽172，并且卡环安装在凹槽中。卡环轴向保持平衡坝。平衡坝将流体保留在活塞144与平衡坝166之间的平衡室174中以抵消来自液压室158中的旋转流体的动态效应。也就是说，当液压室158中的流体旋转时，离心效应即使在没有用于室158中的流体的任何接合压力的情况下也迫使流体将活塞径向向外推动成接合离合器。平衡室中的旋转流体经受类似的动态效应并且抵消室158中的效应，使得活塞基本上保持平衡并且离合器中的阻力受到限制。弹簧176将活塞144远离平衡坝166推动。
电动马达转子106包括旋转变压器适配器板178和旋转变压器转子180。旋转变压器适配器板包括具有轴向槽184的径向外环部分182、具有轴向槽188的径向内环部分186以及从内环部分延伸至外环部分的锥形连接器部分190。旋转变压器转子包括安装在轴向槽184中的键192，并且内周表面124包括安装在轴向槽188中的键194。旋转变压器适配器板还包括接触旋转变压器转子的轴向面198的径向壁196以及接触旋转变压器转子的与轴向面198相对的轴向面202的径向延伸的凸部200。
旋转变压器适配器板与旋转变压器转子具有紧密滑动配合。径向延伸的凸部通过铆固形成。也就是说，旋转变压器适配器板由于旋转变压器适配器板抵靠轴向面202变形而紧密保持在径向壁196与凸部200之间。利用模具(未示出)按压轴向延伸通过旋转变压器转子的材料以轴向地和径向地形成紧密地保持旋转变压器转子的材料。旋转变压器定子203由铆钉204固定至毂156，并且旋转变压器转子和旋转变压器定子一起将转子承载件的旋转位置传达至控制器。安装在活塞承载件114与毂156之间的轴承206将转子106相对于定子104定位，并且允许转子与定子之间的最小摩擦的相对旋转。
电动马达转子106包括固定至转子承载件112的变矩器110。转子承载件112包括环形区段208，并且变矩器110包括固定至环形区段208的环形区段210。转子承载件112包括内周表面212，并且变矩器110包括外周表面214，该外周表面安装在表面212上以用于将变矩器径向定位在转子承载件中。区段208和210以及表面212和214的布置允许将组装的变矩器安装在转子承载件上。也就是说，(例如，由焊缝216)完全组装和焊接的变矩器可以由焊缝218固定至转子承载件112。
混合动力模块100用于将内燃发动机(未示出)连接至多级变速器(未示出)。该模块包括电动马达定子102、具有变矩器110的电动马达转子106、具有离合器内承载件160的模块输入轴220、离合器片122以及离合器片222。变矩器包括在焊缝216处固定至盖壳225的叶轮224、涡轮226以及用于通过传动液体(未示出)传输扭矩的定子228。变矩器还包括：变矩器离合器230，该变矩器离合器用于通过机械连接传输扭矩；以及阻尼器232，该阻尼器布置在涡轮或变矩器离合器与多级变速器之间的扭矩路径中。阻尼器包括输出凸缘234，该输出凸缘布置成用于与多级变速器的输入轴(未示出)驱动接合(例如，在花键236处)。离合器片122与转子承载件驱动地接合，并且离合器片222与离合器内承载件驱动地接合。
尽管上面描述了示例性实施方式，但是这些实施方式并不意在对权利要求所涵盖的所有可能的形式进行描述。说明书中所使用的词语是描述性的而非限制性的词语，并且应当理解的是，在不脱离本公开的精神和范围的情况下可以做出各种改变。如先前所描述的，可以对各种实施方式的各特征进行组合以形成本公开的可能未明确描述或说明的另外的实施方式。尽管各种实施方式可能已经被描述为在一个或更多个期望的特性方面提供优点或者优于其他实施方式或者现有技术实现方式，但是本领域普通技术人员认识到一个或更多个特征或特性可以被折衷以实现期望的整体系统属性，这取决于特定的应用和实现方式。这些属性可以包括但不限于成本、强度、耐久性、寿命周期成本、适销性、外观、包装、大小、适用性、重量、可制造性、易组装性等。因此，在任何实施方式关于一个或更多个特性被描述为不如其他实施方式或现有技术实现方式理想的程度上，这些实施方式没有脱离本公开的范围并且可能被期望用于特定的应用。
