具体实施方式
在开始时，应当领会，在不同附图中出现的相同的附图标记代表相同的或功能上相似的结构元件。此外，应当理解，本发明不仅限于本文所描述的具体实施例、方法理论、材料和修改，而且其当然可以如此变化。还应当理解，本文所使用的术语仅仅是为了描述具体方面的目的，而不意图于限定本发明的范围，本发明的范围仅由所附的权利要求书限定。
除非另外限定，本文所使用的所有技术术语和科学术语都具有与本发明所属领域的普通技术人员通常理解相同的含义。尽管可以在实践或测试本发明时使用任意类似或等同于本文描述的那些方法、装置或材料，但是现在描述以下示例性的方法、装置和材料。
参照图1-3来进行以下描述。图1是混合动力模块的示例性实施例的截面图。图2是图1的截面图，其中箭头指示流动通道。图3是图1的截面图，其中箭头指示流动通道。混合动力模块100包括具有流动通道104的电机壳体102。电动机106包括转子108和定子110。轴112与转子驱动地接合，并且包括布置为与流动通道104流体连通的流动通道114。即，壳体102的隔板包括从流动通道104径向向内延伸以流体连接通道104和114的流动通道(未示出)。
扭矩转换器壳体116驱动地接合到转子。背板118固定到扭矩转换器壳体。活塞120密封到扭矩转换器壳体和背板。例如，活塞120可以通过片簧121与壳体驱动地接合。该活塞形成流体腔122和流体腔124的至少一部分。毂126固定到壳体116并且包括布置为与流动通道114及流体腔124流体连通的流动通道128。尽管示出的流动通道128布置为与流体腔124流体连通，但是其他实施例(未示出)可以具有布置为与流体腔122流体连通的流动通道128。
流体腔122为活塞120提供平衡。即，在壳体116通过转子108或内燃机(未示出)转动期间，腔122和124中的动压得到均衡，使得活塞120更容易通过腔124中的压力变化来控制。换句话说，腔122和124减小或消除了活塞120上的动态油压效应。通过用于将活塞密封到壳体和将背板密封到活塞的密封件的基本相同的径向位置，进一步改善了这种效应。
模块100包括用于将毂密封到轴的密封件130和132。流体腔122至少部分地由扭矩转换器壳体形成，并且流体腔124至少部分地由背板形成。毂126包括布置为与流体腔122流体连通的流动通道134。经由通道134接收在腔122中的油确保上述活塞平衡。扭矩转换器壳体116、背板118和/或活塞120可以包括轴向孔或故意的密封泄漏，以排出捕获的空气并且确保腔122和/或腔124的完全填充。毂126可以包括与流动通道134流体连通的流动通道136，用于向电动机提供冷却流。
参照图4来进行以下描述。图4是图1的混合动力模块的替代实施例的横截面图，其中为了清楚起见未示出电动机和电机壳体。以下除非另外指出，否则所有2XX标记总地对应于图1中的1XX标记。混合动力模块200包括由单件材料一体地形成的轴212和毂226。
参照图5来进行以下描述。图5是混合动力模块的示例性实施例的横截面图。混合动力模块300包括具有流动通道304的电机壳体302。电动机306包括转子308和定子310。轴312与转子驱动地接合，并且包括布置为与流动通道304流体连通的流动通道314。扭矩转换器壳体316与转子驱动地接合。模块300包括背板318和密封到扭矩转换器壳体、背板和轴的活塞320。活塞320形成流体腔322和324的至少一部分。
壳体316例如通过密封件326密封到轴312。流体腔322至少部分地由扭矩转换器壳体形成，并且流体腔324至少部分地由背板形成。流动通道314布置为与流体腔322流体连通。
参照图6来进行以下描述。图6是图5的混合动力模块的替代实施例的横截面图。以下除非另外指出，否则所有4XX标记总地对应于3XX标记。混合动力模块400包括固定到轴412的密封板426。扭矩转换器壳体416密封到密封板。
如果参考图7来进行以下描述。图7是图5的混合动力模块的替代实施例的横截面图。以下除非另外指出，否则所有5XX标记总地对应于3XX标记。混合动力模块500包括用于冷却电动机的流动通道528，流动通道528布置为与流体腔522流体连通。
当然，在不脱离所要求的本发明的精神或范围的情况下，对本发明的以上示例的变化和修改对本领域普通技术人员应当是显而易见的。虽然通过参照具体的优选和/或示例性实施例来描述本发明，但清楚的是，可以在不脱离所要求的本发明的范围或精神的情况下进行改变。
