具体实施方式
参照图1至图3，根据本公开的教导构造的两级电子驱动单元(EDU)总体由附图标记10表示。EDU 10可分别包括外壳组件12、电动马达14、两级变速器16、差速器组件18以及第一输出轴20和第二输出轴22。在所提供的具体示例中，EDU 10进一步包括被配置为经由传动轴(未示出)从内燃机(未示出)接收旋转动力的机械输入组件24。
在所提供的示例中，外壳组件12限定第一旋转轴线28并包括马达外壳组件30、主外壳32和盖34。马达外壳组件30包括外部马达外壳36和被接纳在外部马达外壳36中并被配置为将电动马达14接纳其中的内部马达外壳38。外壳马达外壳36和内部马达外壳38可协作，以限定一个或多个螺旋状的冷却剂通道40，冷却流体可循环通过该冷却剂通道以去除在电动马达14的操作期间产生的热量。主外壳32横向设置在内部马达外壳38与盖34之间并固定联接到内部马达外壳38和盖34。
主外壳32限定其中接纳有两级变速器16、差速器组件18和机械输入组件24的内腔44。盖34固定联接到主外壳32，以闭合内腔44的其中接纳有差速器组件18的部分。
参照图4，电动马达14可包括固定联接到内部马达外壳38的定子50、被接纳在定子50中并能够围绕第一旋转轴线28旋转的转子52、以及固定联接到转子52以随其旋转的马达轴54。在所提供的示例中，马达轴54为中空结构，该中空结构经由一对轴承58被支撑为相对于马达外壳组件30旋转。马达轴54可以是中空的，并可延伸到主外壳32中的内腔44内。
参照图5，两级变速器16可包括第一行星级60、第二行星级62和变速器输出部64。第一行星级60可包括：可形成在电动马达14的马达轴54上或能旋转地联接到电动马达14的马达轴54的第一恒星齿轮70、不可旋转地联接到主外壳32的第一内齿轮72、第一行星架74和多个第一行星齿轮组76。第一行星架74可包括第一架体和固定联接到第一架体的多个销。第一行星齿轮组76中的每个与第一恒星齿轮70和第一内齿轮72啮合，并可具有一个或多个行星齿轮。在所提供的示例中，第一行星齿轮组76中的每个具有与第一恒星齿轮70和第一内齿轮72二者均啮合的单个行星齿轮。然而，将认识到，第一行星齿轮组76中的每个可包括两个或多个行星齿轮，其中第一个行星齿轮与第一恒星齿轮70啮合，第二个行星齿轮与第一内齿轮72和第一个行星齿轮啮合。第一行星齿轮组76中的每个行星齿轮由第一行星架74的相关一个销来轴支撑。
第二行星级62可包括：可形成在第一行星架74的第一架体上或能旋转地联接到第一行星架74的第一架体的第二恒星齿轮80、不可旋转地联接到主外壳32的第二内齿轮82、第二行星架84和多个第二行星齿轮组86。
第二行星架84可包括第二架体和固定联接到第二架体的多个销。第二行星齿轮组86中的每个与第二恒星齿轮80和第二内齿轮82啮合，并可具有一个或多个行星齿轮。在所提供的示例中，第二行星齿轮组86中的每个具有与第二恒星齿轮80和第二内齿轮82二者均啮合的单个行星齿轮。然而，将认识到，第二行星齿轮组86中的每个可包括两个或多个行星齿轮，其中第一个行星齿轮与第二恒星齿轮80和另一个行星齿轮啮合，第二个行星齿轮与第二内齿轮82和另一个行星齿轮啮合。第二行星齿轮组86中的每个行星齿轮由第二行星架84的相关一个销来轴支撑。
参照图6，变速器输出部64为具有第一组齿90、第二组齿92和第三组齿94的套筒状结构。第一组齿90包括被配置成与形成在第一行星架74的第一架体上的配合的一组外齿100啮合的内齿。第二组齿92包括被配置成与形成在第二行星架84的第二架体上的配合的一组内齿102啮合的外齿。在所提供的具体示例中，第二组齿92被设置在第一组齿90的径向外侧而无轴向偏移，而配合的一组内齿102沿着第一旋转轴线28从配合的一组外齿100偏移。这种方式的构造允许变速器输出部64沿着第一旋转轴线28在第一位置、第二位置和在第一位置与第二位置之间的第三位置之间移动，在第一位置中，第一组齿90与第一架体上的配合的外齿100接合，并且第二组齿92与第二架体上的内齿102脱离；在第二位置中，第一组齿90与第一架体上的配合的外齿100脱离，并且第二组齿92与第二架体上的内齿102接合；在第三位置中，第一组齿90与第一架体上的配合的外齿100脱离，第二组齿92与第二架体上的内齿102脱离。第三组齿94可包括内齿。
可采用任何期望的装置选择性地使变速器输出部64在第一位置、第二位置和第三位置之间平移。在所提供的具体示例中，采用具有离合器叉110的致动器选择性地使变速器输出部64平移。离合器叉110可包括一对臂，该一对臂可被接纳在形成于变速器输出部64的外圆周表面的槽112中。
参照图7，差速器组件18可分别包括差速器输入部130以及第一差速器输出部132和第二差速器输出部134。差速器组件18可为任意类型的机构，其可允许在差速器输入部130与第一差速器输出部132和第二差速器输出部134之间进行扭矩传输，同时能够允许第一差速器输出部132与第二差速器输出部134之间的速度差。本示例的差速器组件18包括差动齿轮组，但将认识到，差速器组件可包括一个或多个摩擦离合器。在所提供的具体示例中，差速器输入部130为差速箱，差动齿轮组为锥齿轮组，其包括：联接到差速箱以在垂直于第一轴线的朝向上随其旋转的插销(未示出)；能旋转地安装在插销上的多个差速小齿轮140；以及各自与差速小齿轮140啮合的第一侧齿轮和第二侧齿轮(即，分别为第一差速器输出部132和第二差速器输出部134)。差速器组件18可被配置成其中第一差速器输出部132与第二差速器输出部134之间的速度差不受限制的开放式差速器。可替代地，差速器组件18可为如所示的锁定类型或限滑差速器组件。在此示例中，离合器总成(clutch pack)150设置在差速器输入部130(差速器箱)与第一差速器输出部132之间。离合器总成150包括：轴向能滑动但不可旋转地联接到差速器输入部130的第一组离合器片；以及与第一组离合器片交错并轴向能滑动但不可旋转地联接到第一输出轴22的第二组离合器片。因为第一差速器输出部132固定地但不可旋转地联接到第一输出轴22，第一组离合器片也轴向能滑动但不可旋转地联接到第一差速器输出部132。可使用诸如液压缸的任何类型的线性马达、滚珠坡道式(ball-ramp)致动器或任何其他类型的机械致动器来压缩离合器总成，由此将第一差速器输出部132与差速器输入部130摩擦联接至期望程度。在此示例中图示的差速器组件18可以第一模式和第二模式操作。在第一模式中，离合器总成150未被压缩，因而，并未将差速器输入部130旋转联接(rotationally couple)到第一输出轴22/第一差速器输出部132，因而，差速器组件18作为开放式差速器操作(即，差速器组件18不限制第一差速器输出部132与第二差速器输出部134之间的速度差)。在第二模式中，离合器总成150被充分压缩，因而，能将旋转动力从差速器输入部130传输到第一输出轴22/第一差速器输出部132，从而使第一输出轴22/第一差速器输出部132与差速器输入部130共同旋转。在此状况下，差速器组件18抑制第一差速器输出构件132与第二差速器输出构件134之间的速度差。
参照图2至图7，两级变速器16的变速器输出部64轴向能滑动但不可旋转地联接到差速器输入部130。在所提供的示例中，变速器输出部64上的第三组齿94包括内齿，该内齿与形成在差速器输入部130的套筒状部分上的外齿158啮合，该套筒状部分沿着第一旋转轴线28轴向设置在第二差速器输出部134与第一行星架74之间。因而，将认识到，变速器输出部64联接到差速器输入部130，以便绕第一旋转轴线28共同旋转，而不论变速器输出部64是否处于其第一位置、第二位置或第三位置。
第一输出轴20可联接到第一差速器输出部132以随其旋转，而第二输出轴22可被接纳穿过电动马达14的马达轴54并联接到第二差速器输出部以随其旋转。在所提供的的示例中，第一输出轴20和第二输出轴22中的每一个为加伸轴，具有与其联接的等速接头的外轴承座圈170。
参照图8，机械输入组件24可被配置成从横向于或垂直于第一旋转轴线28定向的旋转轴接收旋转动力以驱动差速器输入部130。在所提供的具体示例中，机械输入组件24被配置成以沿着第一旋转轴线28从旋转轴线偏移的方式驱动差速器输出部130，旋转动力围绕该旋转轴线输入至机械输入组件24。将认识到，沿着图示的第一旋转轴线28的偏移可大于或小于附图中所示。在所提供的示例中，机械输入组件24包括第一轴200、第二轴202、用于在第一轴200与第二轴202之间传输旋转动力的变速器204以及输出齿圈206和输出小齿轮208。第一轴200被配置成联接到传动轴(未示出)以从其接收旋转动力。在所提供的示例中，法兰210安装到第一轴200，并被配置成参与第一轴200与传动轴的机械连接。第二轴202可在垂直于第一旋转轴线28的一个或两个方向上从第一轴200偏移。变速器204可被配置成在第一轴200与第二轴202之间传输旋转动力。在所提供的具体示例中，变速器204包括联接到第一轴200以随其旋转的第一斜齿轮216以及联接到第二轴202以随其旋转并与第一斜齿轮216啮合的第二斜齿轮218。输出齿圈206联接到差速器输入部130，以围绕第一旋转轴线28共同旋转。在所提供的示例中，输出齿圈206为诸如准双曲面齿轮的螺旋锥齿轮。输出小齿轮208可联接到第二轴202以随其旋转，并可与输出齿圈206啮合。
实施例的上述描述是为了说明和描述的目的而提供的。其并非旨在穷举或限制本公开。特定实施例的单个元件或特征通常不限于该特定实施例，而是在适用的情况下是可互换的，并且即使未具体示出或描述，也可以在所选实施例中使用。其也可以多种方式变化。这样的变化不被认为是脱离本公开，并且所有这样的变更旨在包括在本公开的范围内。
