Description

具有电机选择性助力器的双电机共同驱动系统
引言
混合动力驱动车辆通常采用内燃机和至少一个电机的组合。电机通常是电动发电机，使得其可以选择性地将旋转力施加到车辆传动系以推进车辆，或者产生电力以存储在车辆电池中。混合动力车辆可以使用电机、内燃机或两者为车轮提供动力。
电机通常具有限定的操作效率范围，在这一范围中，相对于消耗的电功率，电机提供最大量的旋转力或动力。更大范围的操作效率必然增加电机的复杂性和/或成本。因此，制造商通常必须在电机设计中做出妥协，在较低的电机速度下牺牲效率以在较高的电机速度下获得较高的效率，反之亦然。因此，混合动力车辆通常在受限的速度范围下使用电机，例如，仅在低于预定阈值的速度下。
因此，需要一种解决上述问题的改进的混合动力传动系。
发明内容
在一个示例性图示中，提供了一种混合动力车辆，其包括内燃机和多个电机。车辆还可包括混合动力传动系。在至少一个示例中，混合动力传动系包括共同驱动操纵器和用于电机的选择性助力器。共同驱动操纵器可具有配置成由内燃机驱动的第一输入，以及配置成由第一电机驱动的第二输入。行星齿轮组可以包括齿圈、太阳齿轮和设置在它们之间的多个行星齿轮，这些行星齿轮通过可旋转的行星齿轮架保持围绕太阳齿轮的间隔关系。第一和第二行星齿轮组中的每一个可具有固定到可旋转轴以与其一起旋转的旋转部件，使得在第二行星齿轮组处从第二电机接收的旋转输入选择性地以包括至少减速比(即，即减速或低速传动齿轮)和增速比(即，超速传动齿轮)的多个齿轮比来驱动可旋转轴。
可选地，混合动力传动系可包括旋转离合器，该旋转离合器配置成选择性地限制第一和第二行星齿轮组的部件之间的相对旋转，该部件例如第一行星齿轮组的第一齿圈和第二行星齿轮组的第二行星齿轮架。旋转离合器还可配置成选择性地限制第二行星齿轮组的第二行星齿轮架相对于第一行星齿轮组的第一齿圈的旋转。
在一些示例中，混合动力传动系可以还包括第一制动离合器，该第一制动离合器配置成选择性地限制第一齿圈的旋转。在至少一些示例中，制动离合器配置成限制第一行星齿轮组的太阳齿轮和第二行星齿轮组的行星齿轮架的旋转。可以以至少一个示例性方式提供第二制动离合器，其中第二制动离合器配置成选择性地限制第二行星齿轮架的旋转。可选地，可以提供输入制动离合器，其配置成选择性地限制例如来自内燃机的第一输入的旋转。
在至少一些方式中，行星齿轮组的部件可以彼此连接以进行同步旋转。例如，第二行星齿轮架可以连接到第一行星齿轮组的第一太阳齿轮以随其旋转。类似地，第一行星齿轮组可包括固定到第二行星齿轮组的第二行星齿轮架以与其一起旋转的第一太阳齿轮。
可选地，共同驱动操纵器包括第三行星齿轮组(除了选择性助力器的那些之外)。在这些示例中，第一输入可以是第三行星齿轮组的行星齿轮架，第二输入可以是第三行星齿轮组的太阳齿轮，并且/或者可旋转轴可以由第三行星齿轮组的齿圈驱动。
可旋转轴可以相对于共同驱动操纵器及其旋转部件同轴布置，或者可以例如以副轴布置偏置。
在一些示例性方法中，用于混合动力传动系中的电机的选择性助力器包括第一和第二行星齿轮组。第一行星齿轮组可包括第一齿圈、第一行星齿轮架和第一太阳齿轮，其中第一行星齿轮架固定到可旋转轴上以随其旋转。第二行星齿轮组可具有第二齿圈和第二太阳齿轮，第二齿圈配置成接收来自电机的输入，第二行星齿轮架固定到第一太阳齿轮以随其旋转，第二太阳齿轮固定到可旋转轴以随其旋转。第一和第二行星齿轮组可配合以在第二齿圈和可旋转轴之间提供多个齿轮比，至少包括减速齿轮比和增速齿轮比。
在至少一些示例中，用于电机的选择性助力器包括旋转离合器，该旋转离合器配置成选择性地将例如是第一行星齿轮组的第一齿圈的第一和第二行星齿轮组的旋转部件固定到第二行星齿轮组的第二行星齿轮架，以随其旋转，从而提供一致齿轮比。选择性助力器还可包括第一制动离合器和第二制动离合器，第一制动离合器配置成选择性地限制第一齿圈相对于固定壳体的旋转，第二制动离合器配置成选择性地限制第二行星齿轮架相对于固定壳体的旋转。
附图说明
下文将结合附图描述本发明的一个或多个实施例，其中相同的标号表示相同的元件，附图中：

图3是描绘图1A-1C的传动系的杠杆图，示出了与内燃机和两个电机的示例性连接。
具体实施方式
提供了混合动力传动系的示例性图示，该混合动力传动系用于采用内燃机和至少一个电动发电机或电机的车辆。示例性图示可以促进实现混合动力模式中的多个电机的最佳利用，该混合动力模式即内燃机和一个或多个电机被用来向车轮提供动力的模式，并且可以促进实现电动车辆模式中的多个电机的最佳利用，在该电动车辆模式中只有电机被用来提供动力。
在一个示例中，通过电机中的一个主电机的选择性助力器，在混合动力模式和电动汽车模式两者之下，来促进实现在共同驱动(即，每个电机向车轮提供动力)中使用的两个电机的最佳利用。更具体地，选择性助力器可用于促进主电机在相对低速传动范围(其中主电机用作低速传动扭矩助力器)和相对高速范围(其中主电机用作超速传动速度助力器)中的使用。此外，共同驱动混合系统，即其中采用多个电机的系统，可以有利地允许使用相对较小的电机而不是单个电机。换句话说，采用单个电机的混合系统通常需要更大的电机。
混合动力传动系的示例性实例可以采用比如两个制动离合器——例如，作为选择性助力器的部件——以分别操纵用于低速传动范围和高速范围的主电机的功率。另外，旋转离合器可用于为电机提供一致驱动(即1：1的齿轮比)。以这种方式，为混合动力模式和电动模式提供了稳健的推进架构，这有利于实现最佳的电机利用和功率操纵。
本文公开的示例性传动系架构总体上是紧凑并模块化的，并且可以以同轴或副轴布置来执行。因此，本文公开的示例性传动系可以以横向发动机/变速器配置(对前轮驱动和电动全轮驱动配置而言是常见的)或纵向发动机变速器配置(对后轮驱动和全轮驱动配置而言是常见的)执行，并且执行为任何方便的车辆大小的部段。
如下面将进一步描述的，示例性车辆传动系可以通过共同驱动操纵器(例如行星齿轮组)向最终驱动单元提供动力。行星齿轮组可包括太阳齿轮、多个行星齿轮、保持行星齿轮绕太阳齿轮保持间隔关系的行星齿轮架，以及齿圈。太阳齿轮、行星齿轮和齿圈可具有任何尺寸或数量的齿轮齿，其便于确保行星齿轮组的操作。(例如，齿圈通常具有比太阳齿轮和各个行星齿轮更多的齿轮齿，如下面将进一步讨论的。)在至少一些示例中，行星齿轮组一起从至少一个传动系的主电机向输出(例如，行星齿轮组的最终驱动单元或中间轴)提供多个齿轮比。行星齿轮组实际上可以为其中一个电机(例如，主电机)提供可切换的齿轮箱，使得在电机之一和输出轴(或者，在副轴布置的情形中，是副轴)之间可以获得至少包括减速齿轮比(即，减速或低速传动齿轮)和增速齿轮比(超速传动齿轮)的多个齿轮比。获得了低速传动转动和超速传动齿轮比，允许电机的最佳运行速度分布在更宽范围的车辆运行速度上。通过提供一致齿轮比(即1：1)可以进一步增强这种灵活性，进一步扩展相对窄范围的最佳电机速度，以在更广的车辆速度范围内使用。
现在转向图1A-1C，示出了示例性车辆传动系100a、100b(统称为100)。车辆传动系100可以用在混合动力车辆中，并且如上所述，可以以同轴配置执行，其示例在图1A中示出，或者以偏置/副轴配置执行，其示例如图1B所示。在图1A和图1B所示的每个图中，旋转部件总体以截面图示出。适用于每种配置的杠杆图在图1C中示出，并且将与随后对示例性传动系操作的描述结合使用。
在图1A-1C的每一个中，车辆传动系100使用内燃机102、第一电机104和第二电机106，以各种模式(将对其进行进一步描述)向车辆最终驱动器130提供动力。所示的内燃机102是汽油/火花点火发动机，但应该理解的是，通常不限制可采用何种类型的内燃机。仅作为一个示例，内燃机102可以是柴油/压缩点火发动机。电机104、106均可以是电动发电机。换句话说，电机104、106均能够通过最终驱动器130选择性地向车轮提供动力。当电机104、106不向最终驱动器130提供动力时，它们可以从传动系运动中产生电能，该电能可以存储在与电机104、106电连通的一个或多个车辆电池(未示出)中。
如图1A-1C中的每一个所示，发动机102和电机104、106各自通过多个行星齿轮组114、116和118选择性地将运动传递给最终驱动器130。电机104、106还可以选择性地从行星齿轮组114、116和118的运动中产生电力。为此，电机104、106可以分别包括定子104a、106a和转子104b、106b。转子104b可以围绕由轴120限定的轴线旋转，而转子106b可以围绕由与行星齿轮组116、118相关联的可旋转轴122(或者，在图1B所示的情况下，为副轴122’，如下面将进一步描述的)限定的轴线旋转。如将从图示和下文描述中理解的，下文描述的行星齿轮组114、116和118的旋转部件也可以大致围绕由轴120、122或122’限定的轴线旋转。
行星齿轮组114、116和118可以具有任何方便的配置，并且通常可以根据行星齿轮组或周转齿轮组原理操作，即，其中各种部件的旋转用于提供不同的输入/输出齿轮比。行星齿轮组114、116和118各自大致包括分别设置在行星齿轮组114、116和118中心的太阳齿轮114s、116s和118s，并限定多个向外延伸的齿轮齿(未示出)。行星齿轮组114、116和118还可以分别包括齿圈114r、116r和118r，齿圈114r、116r和118r从其相应的太阳齿轮114s、116s和118s径向向外设置，并且限定多个径向向内延伸的齿轮齿(未示出)。此外，行星齿轮组114、116和118可各自包括多个行星齿轮11卸/116p/118p，每个行星齿轮114p/116p/118p径向设置在相应的齿圈114r/116r/118r和太阳齿轮114s/116s/118s之间。行星齿轮可各自限定多个齿轮齿(未示出)，齿轮齿与它们相邻的齿圈114r/116r/118r和太阳齿轮114s/116s/118s的齿轮齿啮合。每个行星齿轮组还包括行星齿轮架114c、116c和118c，行星齿轮架114c、116c和118c保持行星齿轮114p/116p/118p环绕太阳齿轮114s、116s和118s成间隔关系并且与行星齿轮114p/116p/118p的中心同步地旋转。
现在参照图1A和图1C，传动系100可以被认为大致包括共同驱动操纵器108和选择性助力器110，每个共同驱动操纵器108和选择性助力器110相配合以向最终驱动器130施加运动(并且，在电机104、106的情况下，向电机104、106提供旋转运动以产生电力)。更具体地，共同驱动操纵器108和选择性助力器110各自连接到可旋转轴，例如输出轴122(如图1A中)或副轴122’(如图1B中所示)。
如图1A和图1C所示，传动系100a是同轴布置，其中输出轴122与操纵器108的旋转轴120平行对齐。共同驱动操纵器108具有第一输入，该第一输入配置成由发动机102驱动，呈行星齿轮组114的行星齿轮架114c的形式。呈行星齿轮组114的太阳齿轮114s形式的第二输入与电机104连接以便旋转。齿圈114r进而固定到轴122和行星齿轮组116的行星齿轮架116c上。或者，在图1B所示的副轴配置中，轴120偏离选择性助力器110的可旋转轴122’，这将在下面进一步讨论。
如图1A和图1B所最佳地示出的，选择性助力器110可包括两个行星齿轮组116、118，每个行星齿轮组116、118相配合以从电机106向最终驱动单元130施加运动。当不主动地向最终驱动单元130施加运动时，电机106还可以响应于从行星齿轮组116、118接收的旋转输入而产生电力。每个行星齿轮组116、118具有固定到轴122上的旋转部件，用于随其旋转。更具体地，行星齿轮组116的行星齿轮架116c和行星齿轮组118的太阳齿轮118s各自固定到轴122或122’以随其旋转。
行星齿轮组116、118相配合以为电机106提供多个齿轮比以驱动轴122或122’。更具体地，电机106直接或通过附加传动装置(图1A-1C中未示出)联接到齿圈118。因此，行星齿轮组118的齿圈118r是电机106的输入，以向轴122或122’(并且最终向最终驱动单元130)提供旋转运动。此外，齿圈118r通过行星齿轮组116和118以多个齿轮比选择性地驱动轴122或122’，所述齿轮比至少包括减速齿轮比(即，此情形下，轴122/122’转动的速度比齿圈118r慢)和超速传动齿轮比(即，此情形下，轴122/122’比齿圈118r转动得更快)，如下将进一步描述的。此外，在一些示例中，除了减速齿轮比和超速传动齿轮比之外，还可以提供一致齿轮比(即，此情形下，轴122/122’以与齿圈118r相同的速度转动)。此外，行星齿轮组116、118以相对紧凑和便宜的布置提供多个齿轮比。
如下文将进一步描述的，由行星齿轮组116、118提供的多个齿轮可以实施为具有一个或多个离合器，该多个离合器可以选择性地将行星齿轮组116、118的旋转部件固定在一起以便旋转，或者选择性地将行星齿轮组116、118的部件旋转限制至固定壳体113。
更具体地，如图1A和1B中最佳所示，将行星齿轮组118的行星齿轮架118c固定至行星齿轮组116的太阳齿轮116s。另外，行星齿轮组116的行星齿轮架116c和行星齿轮组118的太阳齿轮118s都固定至轴122或122’以随其旋转。
另外，制动离合器124选择性地限制行星齿轮组116的齿圈116r相对于传动系的固定壳体113(或者在图1B的示例中，为壳体113b)的旋转。第二制动离合器126配置成选择性地限制行星齿轮架118c相对于壳体113/113b的旋转。此外，由于行星齿轮架118c固定到太阳齿轮116s以随其旋转，因此制动离合器126还可以选择性地限制太阳齿轮116s相对于壳体113的旋转。如下面将进一步描述的，制动离合器124、126可以选择性地在电机106的输入(即，齿圈118r)和轴122或122'之间产生不同的有效齿轮比，包括低速传动齿轮比和超速传动齿轮比。
还如图所示，可以提供旋转离合器128，其配置成选择性地固定行星齿轮组116、118的旋转部件以便一起旋转，即，使得它们以相同的速度旋转。在一些示例中，行星齿轮组116、118的固定部件可以为电机106产生一致齿轮比，即，相对于轴122或122’而言。例如，如图1A和图1C所示，旋转离合器128配置成选择性地限制行星齿轮组118的行星齿轮架118c相对于行星齿轮组116的齿圈116r的旋转。此外，如下面将进一步描述的，旋转离合器128可以连接行星齿轮组116、118的其他旋转部件，以产生用于电机106的一致齿轮比。
传动系100还可包括输入制动离合器112，其选择性地限制第一输入(即轴120)相对于固定壳体113(或者在图1B的示例中，为壳体113a)的旋转。因此，当发动机102未使用时，可以致动输入制动离合器112以防止轴120旋转，并且进而防止行星齿轮组114的行星齿轮架114c旋转。因此，输入制动离合器112的接合使得行星齿轮组114仅具有一个自由度(与输入制动离合器112未被致动时的两个自由度相反)，允许两个电机104、106独立于发动机102运行，因为轴120被阻止旋转。另外，输入制动离合器112可以通过保持其他可旋转部件(例如，轴120)静止来改善传动系100的噪声/振动/不平顺特性。
制动离合器124的致动(以及制动离合器126的释放)可以在齿圈118r与轴122或122'之间产生减速或低速传动齿轮比，从而增加电机106的扭矩输出并起到“扭矩助力器”的作用。更具体地，制动离合器124使齿圈116r相对于壳体113保持静止。结果，电机106转动行星齿轮组118的齿圈118r。齿圈118r使行星齿轮架118c转动，从而也转动太阳齿轮116s(其固定到行星齿轮架118c以随其旋转)。当齿圈116r保持静止时，太阳齿轮116s的旋转使行星齿轮架116c旋转。输出轴122以与行星齿轮架116c相同的速度旋转。应当注意，由于太阳齿轮118s和行星齿轮架116c彼此固定以便同步旋转(通过轴122或122’)，并且由于行星齿轮架118c和太阳齿轮116s也相互固定以便同步旋转，所以太阳齿轮116s、118s必须各自具有相同的尺寸/配置。另外，与行星齿轮架116c、118c相关联的行星齿轮116p、118p必须各自具有相同的尺寸/配置。由于行星齿轮组的齿圈通常总是具有比其相关太阳齿轮更多的齿，所以当制动离合器124被致动时，行星齿轮组116、118的相关部件的任何齿轮尺寸/齿数将导致产生减速齿轮比。
相反，制动离合器126的致动(以及制动离合器124的释放)可在齿圈118r与轴122或122’之间产生增速或超速传动齿轮比，从而提高了相对于电机106的速度，使得选择性助力器成为电机106相对于轴122或122’的“速度助力器”。制动离合器126使行星齿轮架118c和太阳齿轮116s保持静止。结果，由电机106旋转齿圈118r将旋转运动传递给太阳齿轮118s，太阳齿轮118s被固定到轴122或122'上以随其旋转。如上所述，行星齿轮组的齿圈通常总是具有比其相关联的太阳齿轮更多的齿，因此，当制动离合器126被致动时，行星齿轮组116、118的相关部件的任何齿轮尺寸/齿数将产生超速传动齿轮比。
在提供了旋转离合器128的示例中，可以通过将行星齿轮组116、118的部件(例如行星齿轮架118c和齿圈116r)固定在一起(并且释放制动离合器124和126)来产生联合驱动齿轮比。更具体地，由电机106旋转齿圈118r将使得齿圈116r和太阳齿轮116s以相同的速度旋转。因此，行星齿轮架116c将以相同的速度旋转，也以相同的速度转动轴122或122’。通过在减速齿轮比和超速传动齿轮比之间提供另外的齿轮比，联合驱动齿轮比可以提供额外的灵活性。仅仅作为示例，由于每个电机的工作周期总体上更为紧张繁忙，联合驱动齿轮比可以用于插电式混合动力车辆(其可以在仅靠电力模式中具有相对扩展的行驶范围，原因部分在于电池组相对较大)和较大的车辆。
如上所述，示例性传动系100可以以同轴或副轴配置提供。更具体地，图1A中所示的传动系100a直接通过齿圈114r向可旋转轴122施加旋转运动，齿圈114r固定到轴122和行星齿轮架116c以随其旋转。因此，轴122相对于轴120同轴对齐。仅作为示例，这种同轴配置在后轮驱动或全轮驱动车辆中是方便的。
相反，在其他示例中，可以使用副轴配置，其通常可以提供更紧凑的传动系。例如，如图1B所示，传动系100b在其他方面与传动系100a相同，但使用相对于轴120偏置的副轴122’以将动力传递到输出轴140(与同轴轴120和122相反)。例如，齿圈114r可以与正齿轮111啮合，例如通过每个齿轮上的外齿(未示出)啮合。齿轮111进而固定在副轴122'上。副轴122'在其远端具有另外的正齿轮134。齿轮134进而与正齿轮144啮合，正齿轮144固定到输出轴140。因此，副轴122’可以分别驱动或分别由与轴120和/或输出轴140相关联的任何固定比率传动装置(例如正齿轮111和/或134)驱动，该传动装置是方便的。因此，传动系100b在功能上与同轴传动系100a相同，因为两者都由参考图1C、图2和图3中的每一个的杠杆图表示。(在图1C中，未示出由图1B中的正齿轮111、134提供的固定比率传动装置。)在同轴传动系100a中，电机106的旋转部件、齿轮111和134以及行星齿轮组116和118的旋转部件各自围绕与旋转轴122相关联的轴线旋转。相反，在副轴传动系100b中，电机106的旋转部件、正齿轮111和134以及行星齿轮组116和118的旋转部件各自围绕与可旋转副轴122’相关联的轴线旋转。
传动系100b的副轴配置可以提供更紧凑的设计，其适用于前轮驱动或其他应用，在这些应用中，传动系的包装空间非常宝贵。由于若干原因，与同轴配置(例如传动系100a)相比，副轴配置可允许减小传动系100b的整体尺寸。例如，副轴配置的齿圈可以更小，因为外部固定比率传动装置可用于提供任何方便的输出速度，即使使用较小的齿圈，比如通过如上所述的一个或多个正齿轮。另外，副轴和其任何其他输入/输出轴可以在空间上定位在不同的平面中，进一步压缩传动系100b的整体尺寸。例如，在图1B中，副轴122’、输出轴140和输入轴120相对于彼此是非共面的(而在二维图1B中看起来是平面的)。
现在参考图2，其是传动系100a或100b的选择性助力器110的杠杆图，其等同于图1C的杠杆图，更详细地描述了选择性助力器110的操作。行星齿轮组116、118实际上形成可切换的齿轮箱132，其为电机106提供相对于轴122或122’的多个齿轮比。此外，如上所述，轴122或122'也固定到行星齿轮组114的齿圈114r(图2中未示出)以随其旋转。因此，发动机102和/或电机104的输出(发动机102和/或电机104中的每一个通过齿圈114r向轴122或122’输出动力)可以与电机106组合。
如图2所示，当制动离合器124被致动时，齿圈116r被阻止旋转，并且从向着轴122或122’的输入齿圈118r中产生减速齿轮比。更具体地，电机106转动齿圈118r，从而以相同的速度使行星齿轮架118c和太阳齿轮116s一起旋转。固定齿圈116r使行星齿轮架116c响应于太阳齿轮116s的旋转而旋转，从而转动轴122或122’。此外，由于齿圈118r和旋转行星齿轮架118c之间的角速度的减小，轴122或122’的旋转速度小于输入齿圈118r的旋转速度。应当注意，行星齿轮组116、118的太阳齿轮116s、118s和行星齿轮116p、118p的相同尺寸/齿轮齿配置导致太阳齿轮116s、118s具有相同的旋转速度，并且行星齿轮架116c、118c也具有相同的转速。轴122/122’被固定到行星齿轮架116c和太阳齿轮118s以随其旋转，因而相对于输入齿圈118r以减小的角速度旋转，从而在齿圈118r和轴122/122’之间提供减速齿轮比(其精确比率可由行星齿轮组116和118的特定配置确定，例如，每个太阳齿轮116s和118s、齿圈116r和118r以及行星齿轮116p、118p的尺寸/齿轮齿)。
相反，当制动离合器126被致动(并且制动离合器124被释放，允许齿圈116r旋转)时，行星齿轮架118c和太阳齿轮116s均被阻止旋转。因此，电机106转动齿圈118r，并且旋转的行星齿轮118p(其中心由行星齿轮架118c保持静止)转动太阳齿轮118s。此外，太阳齿轮118s以比输入齿圈118r更快的速度转动，这是由于当行星齿轮架118c保持静止时太阳齿轮118s相对于齿圈118r的角速度增加的结果。因此，制动离合器126的致动产生从输入齿圈118r到太阳齿轮118s的超速传动齿轮比(其精确比率可由行星齿轮组118的特定配置确定，例如，每个太阳齿轮118s、齿圈118r和设置在其间的行星齿轮118p的尺寸/齿轮齿)。
旋转离合器128在图2中被示出为选择性地将齿圈116r与行星齿轮架118c连接，以产生从输入齿圈118r到轴122或122’的一致齿轮比。然而，应该理解的是，旋转离合器128可用于产生图2的杠杆图中所示的四个节点中的任何两个独立节点，以产生从输入齿圈118r到轴122或122’的一致齿轮比，从而实现一种设计目的，其与将齿圈116r与行星齿轮架118c相连接的旋转离合器128连接所表明的设计目的相同。
现在转到图3，其是传动系100的简化杠杆图，更详细地讨论了车辆传动系100的示例性操作模式。如上所述，车辆传动系100可选择性地利用发动机102和一个或两个电机104、106，以便向最终驱动单元130提供动力，并产生可存储在一个或多个车辆电池(未示出)中的电能。如图3所示，行星齿轮组114通常通过其齿圈114r向最终驱动器130提供输出，其中，从电机104在其太阳齿轮114s处接收输入，并从内燃机102在其行星齿轮架114c处接收输入。此外，通过齿圈114r处的可切换齿轮箱132接收电机106的输出，齿圈114r固定成与轴122/122’(图3中未示出)和/或最终驱动单元130同步旋转。
在电动车辆模式中，可以致动输入制动器112，从而阻止轴120(参见图1A-1C)和行星齿轮架114c的旋转。因此，车辆可以由电机104、106中的一个或两个驱动。在一个示例中，电机106是相对于传动系100的主电机，主要或甚至专门向最终驱动单元130提供动力。当轴122/122’(参见图1A-1C)的转动也转动齿圈114r时，太阳齿轮114s进而转动，从而向电机104提供旋转输入，从而允许电机104产生电能以存储在车辆电池中。或者，电机104可以通过太阳齿轮114s向驱动单元130提供动力(同时电机106也向最终驱动单元130提供动力)。
发动机102可用于补充提供给最终驱动单元130的电力，例如，当与电机104和/或106相关联的电池电力相对较低时。因此，输入制动器112可以被释放，使得发动机102将动力传递到行星齿轮架114c，从而将旋转力输出到齿圈114r。电机104或106中的一个或两个可用于产生电力，该电力通过经由可切换的齿轮箱132接收旋转输入来对车辆电池/电池进行再充电。此外，可以通过上述不同的齿轮比来改变从齿圈114r接收的旋转输入，从而允许发送到最终驱动单元130和发送到电机106的发动机102的动力之间的分配额度被改变。
示例性传动系100通过由多个行星齿轮组构成的可切换齿轮箱132促进实现电机(例如电机106)的灵活使用。更具体地，具有至少超速传动和低速传动齿轮比的可切换齿轮箱允许灵活使用电机106相对窄的操作速度范围，以在更广的车辆速度范围内向车轮提供动力，或从传动系运动产生电力。
