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，出现在不同的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的形式。这些图不一定是等比例的；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该被解释为限制性的，而是仅作为用于教导本领域的技术人员以多种方式使用各实施方式的代表性依据。如本领域中的普通技术人员将理解的那样，参照各图中的任何图所图示和描述的各种特征可以与一个或更多个其他图中所图示的特征相结合，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的实施方式。然而，各特征的与本公开的教导相一致的各种组合方式和改型对于特定应用或实现方案而言可能是期望的。
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的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，但是现在描述以下的示例方法、装置和材料。
参照单个附图进行以下描述。单个附图图示了根据本公开的示例性方面的混合动力模块的上半部横截面图。混合动力模块100包括分解器组件102。分解器组件包括壳体104、用于电动马达108的分解器定子106、以及夹紧板110。夹紧板包括：径向延伸部分112，该径向延伸部分固定至壳体；径向延伸部分114，该径向延伸部分将分解器定子朝向壳体按压；以及轴向延伸部分116，该轴向延伸部分轴向地布置在径向延伸部分112与114之间。
在图中示出的示例性示例中，分解器组件包括螺栓118，该螺栓在轴向延伸部分的径向外侧延伸穿过径向延伸部分112中的孔口120以将夹紧板固定至壳体。夹紧板弹性变形。换言之，当将夹紧板固定至壳体时，夹紧板的一部分通过分解器定子而变形以对分解器定子进行按压。在图中示出的示例性示例中，夹紧板110包括半圆形部分122，该半圆形部分将轴向延伸部分的与径向延伸部分112相反的远端端部124连接至径向延伸部分114。半圆形部分122在螺栓118被拧紧时发生偏转，从而将分解器定子在壳体与径向延伸部分114之间轴向地夹紧。
夹紧板110可以围绕分解器定子的外径而形成完整的环，或者夹紧板可以是绕轴线126周向分布的多个凸部中的一个凸部。径向延伸部分112可以是环形盘，并且轴向延伸部分可以是在分解器定子的外径128的径向外侧从环形盘延伸的凸部。
如图中所示，分解器定子106包括凹口130，并且壳体104包括布置在该凹口中以用于使分解器定子相对于壳体定位的凸部132。分解器定子通过凹口中的凸部而径向和周向地定位。虽然示出了凸部和凹口，但是其他实施方式也是可能的。例如，分解器定子或壳体中的一者可以包括筒形突出部，并且分解器或壳体中的另一者可以包括用于接纳突出部的凹部或沉孔。另外，分解器组件102可以包括绕轴线126周向分布的多个凸部或突出部。
分解器组件102包括电动马达108和分解器转子136。电动马达包括固定至壳体的定子138以及能够相对于壳体和定子旋转的转子140。轴向延伸部分116径向地设置在电动马达转子的内径141内。分解器转子与分解器定子径向对准并且固定至转子从而共同旋转。换言之，分解器转子和转子一起旋转。分解器组件102还包括轴承142。转子包括转子承载件144，分解器转子固定至转子承载件，并且轴承使转子承载件相对于壳体径向地定位。分解器转子和分解器定子一起工作以通过经由电缆(未示出)将电信号传递至马达控制器来确定电动马达转子相对于电动马达定子的旋转位置。
如图中所示，分解器组件102是混合动力模块100的一部分，该混合动力模块包括具有变矩器离合器148的变矩器146。混合动力模块100还包括用于使电动马达转子与内燃发动机(ICE)的曲轴断开连接的K0离合器150。阻尼器152有助于使ICE扭转波动与混合动力模块隔离。
虽然上文描述了示例性实施方式，但是示例性实施方式并不意在描述权利要求书所涵盖的所有可能形式。说明书中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，可以在不偏离本公开的精神和范围的情况下做出各种变型。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。虽然各种实施方式可以在关于一个或更多个期望的特征方面被描述为提供优势或者优于其他实施方式或者现有技术的实现方案，但是本领域中的那些普通技术人员应当意识到的是，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，这取决于特定应用和实现方案。这些属性可以包括但不限于成本、强度、耐用性、生命周期成本、适销性、外观、包装、尺寸、适用性、重量、可制造性、组装的容易性等。由此，在某种程度上，任何实施方式被描述为在一个或更多个特性方面不如其他实施方式或现有技术实现方式更理想，这些实施方式不超出本公开的范围并且对于特定应用而言可能是期望的。
