具体实施方式
以下对变型的描述本质上仅是说明性的，而绝不旨在限制本发明的范围、其应用或用途。
参见图1和图2，在若干变型中，电动全轮驱动双速车辆20、33包括但不限于48伏电动全轮驱动双速车辆，可以包括电气化轴组件18。在若干变型中，电气化轴组件18可以包括轴组件22、38，其可以选择性地被驱动或可以驱动电机122。电机122可以通过减速齿轮系60将动力传输到轴组件22、38的输出差速器25、39。挡位选择器94可操作地附接到减速齿轮系60，以在低挡位模式、高挡位模式和空挡模式之间换挡减速齿轮系60，如将在下文中讨论的。可以使用任意数量的电机122，包括但不限于电动机、电动发电机或其他电机。
在若干变型中，电机122可以包括永磁电动机。永磁电动机可以基本上是正方形的，使得定子123的长度和定子123的直径可以基本上相同，这可以使得电动机122(图3)的效率最大化。这可能要求电动机122安装成轴线与减速齿轮系60、挡位选择器94和输出差速器25、39偏离。
在另一个变型中，可能期望将带式交流发电机起动器(belt alternatorstarter，BAS)电动机重新用作轴组件22、38的推进设备122，这也可能要求电动机122安装成轴线与减速齿轮系60、挡位选择器94和输出差速器25、39偏离。
在若干变型中，链传动装置62可以用于将旋转动力从电机122传输到偏离电机122的轴线安装的输出差速器25、39。链传动装置62可以可操作地连接到电机122，并且可以通过减速齿轮系60将动力从电机122传输到轴组件22、38的输出差速器25、39，其通过挡位选择器94在低挡位模式或高挡位模式选择性地操作，如将在下文中讨论的。进一步，链传动装置62可以通过减速齿轮系60将动力从输出差速器25、39传输到电机122，如将在下文讨论的。

在若干变型中，第二齿轮66可以可操作地附接到第一行星齿轮组70的太阳齿轮72，或者可以与太阳齿轮72成一体，使得太阳齿轮72和第二齿轮66可以一起旋转。在若干变型中，太阳齿轮72可以在中心线支撑轴120上自由旋转。在若干变型中，太阳齿轮72可以可旋转地连接到至少第一行星齿轮74和第二行星齿轮76，使得第一和第二行星齿轮74、76驱动太阳齿轮72或被其驱动。第一行星齿轮74可以在固定到行星架82的第一销78上旋转，第二行星齿轮76可以在也可以固定到行星架82的第二销80上旋转。应当注意的是，根据设计要求，可以使用两个以上的行星齿轮。第一行星齿轮74和第二行星齿轮76可以与内齿环或环齿轮84啮合并在其内旋转。在若干变型中，环齿轮84还可以包括轮毂86，其可以包括可以朝向中心线支撑轴120径向延伸的第一部分88，和可以从第一部分88的端部92沿中心线支撑轴120轴向延伸的第二部分90。在若干变型中，环齿轮轮毂86可以被构造和布置成与挡位选择器94啮合，如将在下文中讨论的。第一行星齿轮组70可以包括任何类型的齿轮，包括但不限于斜齿轮。

在若干变型中，同步器94可以选择性地将输出差速器25、39从电机122断开以提供空挡模式，并且可以将电动机122与差速器25、39连接以提供动力传递的两种操作模式(低和高)。在第一模式中，同步器轮毂96可以选择性地轴向向左换挡，这可以引起第一行星齿轮组70的环齿轮84换挡，使得环齿轮84可以接地到壳体130，使得其可以固定而不旋转。当环齿轮84可以接地时，第一行星齿轮组70的行星架82的转速可以降低并且扭矩可以增加，使得减速齿轮系60可以在低挡位操作模式下执行。在第二模式中，同步器轮毂96可以选择性地轴向向右换挡，这可以引起第一行星齿轮组70的环齿轮84换挡，使得环齿轮84可以通过中心线支撑轴120可操作地连接到第一行星齿轮组70的行星架82，使得其可以与可操作地连接到中心线支撑轴120的行星架82一起旋转。当环齿轮84通过中心线支撑轴120连接到行星架82时，可以保持太阳齿轮72的转速，使得减速齿轮系60可以在高挡位操作模式下执行。
在若干变型中，来自第一行星齿轮组70的输出可以被传递到第二行星齿轮组98，以驱动输出差速器25、39。第二行星齿轮组98可以包括太阳齿轮100和可操作地连接到太阳齿轮100的第一和第二行星齿轮102、104，使得第一和第二行星齿轮102、104驱动太阳齿轮100或被其驱动。第一和第二行星齿轮102、104可以分别地通过第一和第二销106、108可操作地附接到行星架110，并且可以在环齿轮112内旋转。应当注意的是，根据设计要求，可以使用两个以上的行星齿轮。在若干变型中，第二行星齿轮组98的环齿轮112可以在由壳体130的表面限定的延伸环形壁132处接地到壳体130，使得其可以固定而不旋转。第二行星齿轮组98可以包括任何类型的齿轮，包括但不限于斜齿轮。在若干变型中，挡位选择器94可以将第一行星齿轮组70的环齿轮84从第一行星齿轮组70的行星架82和壳体130断开，使得环齿轮84从第二行星齿轮组98的太阳齿轮100断开，以提供空挡模式。
在若干变型中，加油***134可以与链传动装置62的链68流体连通。加油***134可以被构造和布置成在链68的内表面69上喷射油，以润滑链68。在一种变型中，加油***134可以包括第一导管136和垂直于第一导管136的第二导管138。在若干变型中，第一导管136和/或第二导管138可以被限定在壳体130的内表面131内，或者可以是管道。在若干变型中，第一导管136可以与油槽148流体连通，并且第二导管138可以延伸到链68的内表面69。第一道管136可以从油槽148汲取油，并且可以引导油通过第二道管138，使得油可以从第二道管138喷射到链68的内表面69上。上述加油***仅用于说明的目的，并且应当注意的是，可以使用任何数量的加油***来润滑链条。
在若干变型中，一个或多个特征可以结合到电气化轴组件18中，以管理油槽水平并且减少剪切损失，诸如在专利申请14/824,724号中公开的，该专利申请通过引用结合于本文。
