技术领域
本发明涉及混合动力电动车辆的动力传输装置。
背景技术
车辆的环境友好型技术是控制未来车辆工业生存的核心技术，并且先进的车辆制造商已将他们的精力集中在开发环境友好型车辆上，以实现环境和燃油效率的法规。
因此，作为未来车辆技术，车辆制造商已经开发出电动车辆(EV)、混合动力电动车辆(HEV)、燃料电池电动车辆(FCEV)等。
由于未来车辆具有诸如重量和成本的各种技术限制，因此车辆制造商已关注混合动力电动车辆作为现实问题的替代方案，以符合排放气体的法规并提高燃料效率性能，并且车辆制造商已经进入将混合动力电动车辆商业化的激烈竞争中。
混合动力电动车辆是使用两个或两个以上动力源的车辆。可以通过各种方案来组合两个或两个以上动力源，并且将使用传统化石燃料的汽油发动机或柴油发动机与由电能驱动的电动机-发电机混合并且用作动力源。
在混合动力电动车辆中，根据发动机和电动机的结合，可以实现：仅由电动机驱动混合动力电动车辆的EV模式、使用发动机和电动机两者的HEV模式以及仅使用发动机的ENG模式。另外，混合动力电动车辆可以通过在车辆停止时停止发动机的怠速停止功能以及通过再生制动来显著提高燃料效率，在再生制动中，将电动机-发电机作为发电机驱动，以通过车辆在制动情况下的动能来发电，这样产生的电力被存储在电池中，并且在驱动车辆时重新使用所存储的电力。
混合动力电动车辆的变速器基于发动机和电动机-发电机的扭矩，执行换挡操作。这样的变速器可以通过额外地将可变地连接至发动机的发动机离合器应用于传统多速(例如，六速)的自动变速器，来实现各种模式的多速(例如六速)。
这种混合动力电动车辆的变速器，类似于传统的六速自动变速器，通常可以包括三个行星齿轮组、六个操作元件和至少一个单向离合器OWC，以及额外的发动机离合器。通过这样的方案，混合动力电动车辆的变速器可以理解为并未针对混合动力电动车辆进行最佳优化，并且可以改进以提供更高的效率、更好的性能、更好的燃料消耗或更少的生产成本。
本发明的背景技术部分所包含的信息仅用于加强对本发明的一般背景的理解，而不可以被视为承认或任何形式的暗示该信息组成本领域技术人员已知的现有技术。

第一行星齿轮组可以形成为具有作为第一旋转元件的第一太阳齿轮、作为第二旋转元件的第一行星架以及作为第三旋转元件的第一齿圈的单小齿轮行星齿轮组。第二行星齿轮组可以形成为具有作为第四旋转元件的第二太阳齿轮、作为第五旋转元件的第二行星架以及作为第六旋转元件的第二齿圈的单小齿轮行星齿轮组。

第一制动器可以安装于第二行星齿轮组与电动机-发电机之间。第二制动器可以安装于第一行星齿轮组的径向外部。
第一制动器和第二制动器可以安装于第二行星齿轮组与电动机-发电机之间。

多个接合元件可以包括：第一离合器，安装于第一轴与输入轴之间；第二离合器，安装于第三轴与第五轴之间；第三离合器，安装于第二轴与输入轴之间；第一制动器，安装于第四轴与变速器壳体之间；以及第二制动器，安装于第三轴与变速器壳体之间。
另外，单向离合器可以安装于输入轴与发动机输出轴之间。
根据基于本发明的示例性实施方式的混合动力电动车辆的动力传输装置，在通过仅采用两个行星齿轮组简化变速器结构的同时，可以实现各种换挡模式，例如分别具有四档位的发动机模式和并联混合动力模式、电控无级变速模式(eCVT模式)以及具有四档位的电动车辆模式(EV模式)，从而降低生产成本，并且实现高于等效变速器的燃油消耗特性和动力性能。
另外，与传统的六速变速器相比，可以减少所采用的行星齿轮组的数量，因此，可以减少总长度，从而提高装入车辆中的可安装性。
另外，在输入轴与发动机输出轴之间安装有单向离合器OWC，从而可以在EV模式下和再生制动中避免发动机阻力。

附图和说明应视为本质上是说明性的而非限制性的，并且在整个说明书中，相同的附图标记表示相同的元件。
在下面的描述中，因为部件的名称彼此相同并且其顺序没有特别限制，所以将部件的名称区分为第一、第二等以区分名称。
图1是根据本发明的各种示例性实施方式的混合动力电动车辆的动力传输装置的示意图。
参照图1，根据各种示例性实施方式的混合动力电动车辆的动力传输装置从发动机ENG和电动机-发电机MG的动力源接收扭矩，并且包括输入轴IS、第一行星齿轮组PG1和第二行星齿轮组PG2、分别连接第一行星齿轮组PG1和第二行星齿轮组PG2的旋转元件的五个轴TM1至TM5，以及作为接合元件的三个离合器C1至C3与两个制动器B1和B2。
因此，通过第一行星齿轮组PG1与第二行星齿轮组PG2的协同操作，使从发动机ENG和电动机-发电机MG输入的扭矩改变，并且改变的扭矩通过输出齿轮OG输出。
发动机ENG是主要动力源，并且可以由诸如汽油发动机或柴油发动机的各种类型中的一种来实现。
电动机-发电机MG固定连接至行星齿轮组部PG，并且用作辅助动力源。
电动机-发电机MG既可以用作电动机，也可以用作发电机，并且包括定子ST和转子RT，其中定子ST固定至变速器壳体H，而转子RT内部地安装于定子ST中并且相对于定子ST可旋转。
输入轴IS是输入构件，并且可以通过发动机输出轴接收发动机ENG的扭矩。
输出齿轮OG是输出元件，并且可以通过差动装置将改变的扭矩传递至驱动轴。
第一行星齿轮组PG1是单小齿轮行星齿轮组，并且可以包括：第一太阳齿轮S1的第一旋转元件N1、第一行星架PC1的第二旋转元件N2以及第一齿圈R1的第三旋转元件N3，第一行星架PC1可旋转地支撑与第一太阳齿轮S1外齿轮啮合的多个第一小齿轮P1；第一齿圈R1与多个第一小齿轮P1内齿轮啮合。
第二行星齿轮组PG2是单小齿轮行星齿轮组，并且包括：第二太阳齿轮S2的第四旋转元件N4、第二行星架PC2的第五旋转元件N5、以及第二齿圈R2的第六旋转元件N6，第二行星架PC2可旋转地支撑与第二太阳齿轮S2外齿轮啮合的多个第二小齿轮P2，第二齿圈R2与多个第二小齿轮P2内齿轮啮合。
即，根据各种示例性实施方式的混合动力电动车辆的动力传输装置由第一行星齿轮组PG1和第二行星齿轮组PG2的组合形成，并且包括五个轴TM1、TM2、TM3、TM4和TM5。
第一旋转元件N1至第六旋转元件N6固定连接至轴TM1至TM5中相应的一个轴，并且通过包括至少一个离合器和至少一个制动器的多个接合元件操作第一行星齿轮组PG1和第二行星齿轮组PG2。
在下文中将详细地描述五个轴TM1至TM5。
第一轴TM1固定连接至第一旋转元件N1(第一太阳齿轮S1)和电动机-发电机MG，并且在用作电动机-发电机MG的输入元件的同时，第一轴TM1选择性地可连接至输入轴IS，从而选择性地用作发动机ENG的输入元件。
第二轴TM2固定连接第二旋转元件N2(第一行星架PC1)和第六旋转元件N6(第二齿圈R2)，并且选择性地可连接至输入轴IS，从而选择性地用作输入元件。
第三轴TM3固定连接至第三旋转元件N3(第一齿圈R1)，并且选择性地可连接至变速器壳体H，从而选择性地用作固定元件。
第四轴TM4固定连接至第四旋转元件N4(第二太阳齿轮S2)，并且选择性地可连接至变速器壳体H，从而选择性地用作固定元件。
第五轴TM5固定连接至第五旋转元件N5(第二行星架PC2)，选择性地可连接至第三轴TM3，并且固定连接至输出齿轮OG，从而始终用作输出元件。
在本发明的示例性实施方式中，当将两个或以上构件被描述为“固定连接”时，其中各构件可以是轴、输入轴、输出轴、旋转构件以及变速器壳体中的任何一者，这意味着固定连接的构件始终以相同的速度旋转。
当将两个或以上构件描述为通过接合元件“选择性地可连接”时，这意味着，当接合元件未接合时，选择性地可连接的构件分别旋转，而当接合元件接合时，选择性地可连接的构件以相同的速度旋转。
可以理解的是，在构件通过接合元件“选择性地可连接”至变速器壳体的情况下，当接合元件接合时，该构件可以是静止的。
作为接合元件的第一离合器C1、第二离合器C2和第三离合器C3安装于五个轴TM1至TM5与输入轴的相应对之间，以形成选择性连接。
在变速器壳体H与五个轴TM1至TM5中的相应轴之间安装有作为接合元件的第一制动器B1和第二制动器B2，以形成选择性连接。
如下安装作为五个接合元件的三个离合器C1、C2和C3以及两个制动器B1和B2。
第一离合器C1安装于第一轴TM1与输入轴IS之间，并且选择性地连接第一轴TM1和输入轴IS，从而控制第一轴TM1与输入轴IS之间的动力传递。
第二离合器C2安装于第三轴TM3和第五轴TM5之间，并且选择性地连接第二轴TM2和第五轴TM5，从而控制第二轴TM2与第五轴TM5之间的动力传递。
第三离合器C3安装于第二轴TM2与输入轴IS之间，并且选择性地连接第一轴TM1和输入轴IS，从而控制第一轴TM1与输入轴IS之间的动力传递。
第一制动器B1安装于第四轴TM4与变速器壳体H之间，并且选择性地将第四轴TM4连接至变速器壳体H。
第二制动器B2安装于第三轴TM3与变速器壳体H之间，并且选择性地将第三轴TM3连接至变速器壳体H。
第一制动器B1安装于第二行星齿轮组PG2与电动机-发电机MG之间，并且第二制动器B2安装于第一行星齿轮组PG1的径向外部。
作为接合元件的第一离合器C1、第二离合器C2与第三离合器C3以及第一制动器B1与第二制动器B2可实现为通过液压摩擦接合的多片式液压摩擦装置，然而，因为可以使用电可控的各种其它配置，因此可以理解为不局限于此。
图2是根据图1的各种示例性实施方式的混合动力电动车辆的动力传输装置的操作图表。
参照图2，根据各种示例性实施方式的混合动力电动车辆的动力传输装置实现分别具有四个固定档位的发动机模式(混合动力模式)和EV模式，并且还实现促进电控无级变速的eCVT模式。
在发动机模式(混合动力模式)下，发动机ENG运行。在瞬时状态下，通过第一离合器C1和第三离合器C3中的至少一者的操作，将发动机ENG的扭矩输入到第一行星齿轮组PG1，并且控制第二离合器C2与第一制动器B1以及第二制动器B2以实现四个固定的档位。
在eCVT模式下，发动机ENG以固定的转速运行，并且接合第三离合器C3，以将发动机ENG的扭矩传输到第二轴TM2。同时，操作连接至第一轴TM1的电动机-发电机MG，以向第一旋转元件N1传递电动机扭矩，并且改变电动机-发电机MG的转速以改变变速器的传动比，从而实现用于高档的传动比(传动比小于1.0)。
在EV模式下，释放第一离合器C1，以使第一行星齿轮组PG1从发动机ENG断开，并且同时，将电动机-发电机MG的扭矩通过第一轴TM1传输至第一旋转元件N1。与发动机模式相似，控制第二离合器C2与第三离合器C3以及第一制动器B1与第二制动器B2以实现四个EV固定档位。
在此，可以组合发动机模式(混合动力模式)与eCVT模式，以实现至少五速的换挡模式。
即，在发动机模式下保持第一前进速度至第四前进速度的档位的同时，可以通过执行电控无级变速的eCVT模式来实现超速OD，以实现适于高档的传动比。
在下文中，结合各个模式详细地描述根据各种示例性实施方式的混合动力电动车辆的动力传输装置的操作。
[发动机模式第一前进速度(混合动力模式第一前进速度)]
在发动机模式第一前进速度下，运行发动机ENG，并且同时操作第一离合器C1以及第一制动器B1和第二制动器B2。
因此，第四轴TM4通过第一制动器B1的操作而用作固定元件，并且第三轴TM3通过第二制动器B2的操作而用作固定元件。在瞬时状态下，通过第一离合器C1的操作，将发动机ENG的扭矩通过第一轴TM1输入至第一旋转元件N1。
因此，速度降低的输出被传递到第一行星齿轮组PG1和第二行星齿轮组PG2的第五旋转元件N5，并且通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG，输出发动机模式第一前进速度的扭矩。
在此，当驱动电动机-发电机MG时，电动机-发电机MG的转矩被添加至第一轴TM1，因此，可以实现混合动力模式的第一前进速度。
[发动机模式第二前进速度(混合动力模式第二前进速度)]
在发动机模式第二前进速度下，运行发动机ENG，并且同时操作第一离合器C1和第二离合器C2以及第一制动器B1。
因此，第四轴TM4通过第一制动器B1的操作而用作固定元件。在瞬时状态下，第三轴TM3和第五轴TM5通过第二离合器C2的操作而互相连接，并且通过第一离合器C1的操作，将发动机ENG的扭矩通过第一轴TM1输入至第一旋转元件N1。
因此，速度降低的输出被传递到第一行星齿轮组PG1和第二行星齿轮组PG2的第五旋转元件N5，并且通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG，输出发动机模式第二前进速度的扭矩。
在此，当驱动电动机-发电机MG时，电动机-发电机MG的转矩被添加至第一轴TM1，因此，可以实现混合动力模式的第二前进速度。
[发动机模式第三前进速度(混合动力模式第三前进速度)]
在发动机模式第三前进速度下，运行发动机ENG，并且同时操作第一离合器C1和第三离合器C3、第一制动器B1。
因此，第四轴TM4通过第一制动器B1的操作而用作固定元件。在瞬时状态下，通过第一离合器C1和第三离合器C3的操作，将发动机ENG的扭矩通过第一轴TM1输入至第一旋转元件N1，并且通过第二轴TM2输入至第二旋转元件N2和第六旋转元件N6。
因此，速度降低的输出被传递到第一行星齿轮组PG1和第二行星齿轮组PG2的第五旋转元件N5，并且通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG，输出发动机模式第三前进速度的扭矩。
在此，当驱动电动机-发电机MG时，电动机-发电机MG的转矩被添加至第一轴TM1，因此，可以实现混合动力模式的第三前进速度。
[发动机模式第四前进速度(混合动力模式第四前进速度)]
在发动机模式第四前进速度下，运行发动机ENG，并且同时操作第一离合器C1与第二离合器C2以及第三离合器C3。
因此，第三轴TM3和第五轴TM5通过第二离合器C2的操作而互相连接，并且通过第一离合器C1和第三离合器C3的操作，将发动机ENG的扭矩同时输入至第一轴TM1与第二轴TM2。因此，第一行星齿轮组PG1和第二行星齿轮组PG2整体地旋转。
因此，在第一行星齿轮组PG1和第二行星齿轮组PG2中，输入扭矩通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG直接输出(以1∶1的比例)，从而输出发动机模式第四前进速度的扭矩。
在此，当驱动电动机-发电机MG时，电动机-发电机MG的转矩被添加至第一轴TM1，因此，可以实现混合动力模式的第四前进速度。
在这种发动机模式下，当在发动机ENG运行的情况下停止车辆时，可以操作第一离合器C1，以将发动机ENG的扭矩传输至电动机-发电机MG，从而产生电力以对电池充电。
[eCVT模式]
在eCVT模式下，以固定的转速运行发动机ENG，并且操作第二离合器C2和第三离合器C3。
因此，第三轴TM3和第五轴TM5通过第二离合器C2的操作而相互连接，操作第三离合器C3，以将发动机ENG的扭矩传输至第二轴TM2，并且同时将连接至第一轴TM1的电动机-发电机MG的扭矩传输至第一旋转元件N1。
在这种状态下，可以通过改变电动机-发电机MG的转速，来实现具有适合于高档的传动比的eCVT模式。
[EV模式第一速度]
在EV模式第一速度下，释放第一离合器C1，以断开发动机ENG。在瞬时状态下，同时操作第一制动器B1和第二制动器B2，并且运行电动机-发电机MG。
因此，第四轴TM4和第三轴TM3通过第一制动器B1和第二制动器B2的操作而用作固定元件。在瞬时状态下，电动机-发电机MG的扭矩通过第一轴TM1输入至第一旋转元件N1。
因此，速度降低的输出被传递到第一行星齿轮组PG1和第二行星齿轮组PG2的第五旋转元件N5，并且通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG，输出EV模式第一速度的扭矩。
[EV模式第二速度]
在EV模式第二速度下，释放第一离合器C1，以断开发动机ENG。在瞬时状态下，同时操作第二离合器C2和第一制动器B1，并且运行电动机-发电机MG。
因此，第三轴TM3和第五轴TM5通过第二离合器C2的操作而互相连接，并且第四轴TM4通过第一制动器B1的操作而用作固定元件。在瞬时状态下，将电动机-发电机MG的扭矩通过第一轴TM1输入至第一旋转元件N1。
因此，速度降低的输出被传递到第一行星齿轮组PG1和第二行星齿轮组PG2的第五旋转元件N5，并且通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG，输出EV模式第二速度的扭矩。
[EV模式第三速度]
在EV模式第三速度下，同时操作第一离合器C1、第三离合器C3和第一制动器B1，运行电动机-发电机MG。
因此，第一轴TM1和第二轴TM2通过第一离合器C1和第三离合器C3的操作而互相连接，并且第四轴TM4通过第一制动器B1的操作而用作固定元件。在瞬时状态下，将电动机-发电机MG的扭矩通过第一轴TM1输入至第一旋转元件N1，并且通过输入轴IS和第二轴TM2输入至第二旋转元件N2。
因此，第一行星齿轮组PG1整体地旋转，并且降低的速度在第二行星齿轮组PG2的第五旋转元件N5处输出。因此，通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG，输出EV模式第三速度的扭矩。
[EV模式第四速度]
在EV模式第四速度下，同时操作第一离合器C1、第二离合器C2和第三离合器C3，并且运行电动机-发电机MG。
因此，因为电动机-发电机MG的扭矩同时输入至第五旋转元件N5和第六旋转元件N6，所以第一行星齿轮组PG1通过第一离合器C1和第三离合器C3的操作而整体地旋转，并且第二行星齿轮组PG2通过第二离合器C2的操作而整体地旋转。因此，第一行星齿轮组PG1和第二行星齿轮组PG2整体地旋转。
因此，在第一行星齿轮组PG1和第二行星齿轮组PG2中，输入扭矩通过经由第五轴TM5连接至第五旋转元件N5的输出齿轮OG直接输出(以1∶1的比例)，从而输出EV模式第四速度的扭矩。
图3是根据各种示例性实施方式的混合动力电动车辆的动力传输装置的示意图。图4是根据各种示例性实施方式的混合动力电动车辆的动力传输装置的操作图表。
参照图3，根据图3中的各种示例性实施方式的混合动力电动车辆的动力传输装置与图1中的各种示例性实施方式的不同之处在于，在输入轴IS与发动机输出轴EOS之间应用单向离合器OWC。
因为单向离合器OWC安装于输入轴IS与发动机输出轴EOS之间，所以可以在EV模式下和再生制动中防止发动机阻力。
因此，根据各种示例性实施方式的混合动力电动车辆的动力传输装置仅在采用单向离合器的特征上不同于各种示例性实施方式，而其他布置保持相同，因此不再详细描述其他布置。
另外，参照图4，仅除单向离合器OWC的操作之外，可以以与图1中各种示例性实施方式中的相同的方式来实现换挡模式，因此，将不再详细描述换挡操作。
图5是根据本发明的各种示例性实施方式的混合动力电动车辆的动力传输装置的示意图。
参照图5，根据各种示例性实施方式的混合动力电动车辆的动力传输装置与图1中的各种示例性实施方式的不同之处在于第一制动器B1和第二制动器B2的位置。
即，在图1中的本发明的各种示例性实施方式中，第一制动器B1位于第二行星齿轮组PG2与电动机-发电机MG之间，并且第二制动器B2位于第一行星齿轮组PG1的径向外部。然而，在图5的本发明的各种示例性实施方式中，第一制动器B1和第二制动器B2位于第二行星齿轮组PG2与电动机-发电机MG之间。
因此，根据图5的各种示例性实施方式的混合动力电动车辆的动力传输装置仅在第一制动器B1和第二制动器B2的位置上不同于图1的各种示例性实施方式，而其他布置保持相同，因此不再详细描述其他布置。
另外，可以以与图1中本发明各种示例性实施方式中的相同的方式来实现换挡模式，因此不再详细地描述换挡操作。
图6是根据本发明的各种示例性实施方式的混合动力电动车辆的动力传输装置的示意图。
参照图6，根据各种示例性实施方式的混合动力电动车辆的动力传输装置与图5中各种示例性实施方式的不同之处在于在输入轴IS与发动机输出轴EOS之间应用单向离合器OWC。
因为单向离合器OWC安装于输入轴IS与发动机输出轴EOS之间，所以可以在EV模式下和再生制动中避免发动机阻力。
因此，根据图6的各种示例性实施方式的混合动力电动车辆的动力传输装置仅在采用单向离合器的特征上不同于图5中的各种示例性实施方式，而其他布置保持相同，因此不再详细描述其他布置。
另外，仅仅除单向离合器OWC的操作之外，可以以与图3中各种示例性实施方式中的相同的方式来实现换挡模式，而其他保持相同，因此将不再详细描述换挡操作。
图7是根据本发明的各种示例性实施方式的混合动力电动车辆的动力传输装置的示意图。
参照图7，根据各种示例性实施方式的混合动力电动车辆的动力传输装置与图5中各种示例性实施方式的不同之处在于第一行星齿轮组PG1的布置。
即，在图5中的本发明的各种示例性实施方式中，第一行星齿轮组PG1形成为单小齿轮行星齿轮组。然而，在图7中的本发明的各种示例性实施方式中，第一行星齿轮组PG1形成为双小齿轮行星齿轮组。
即，图7中的各种示例性实施方式的第一行星齿轮组PG1是双小齿轮行星齿轮组，并且包括：第一太阳齿轮S1的第一旋转元件N1；第一齿圈R1的第二旋转元件N2；第一行星架PC1的第三旋转元件N3，第一齿圈R1与多个第一小齿轮P1内齿轮啮合，多个第一小齿轮P1与第一太阳齿轮S1外齿轮啮合，第一行星架PC1可旋转地支撑多个第一小齿轮P1。
因此，根据图7中的各种示例性实施方式的混合动力电动车辆的动力传输装置仅在采用不同类型的第一行星齿轮组PG1上不同于图5中的各种示例性实施方式，而其他布置保持相同，因此不再详细描述其他布置。
另外，可以以与图1中本发明的各种示例性实施方式中的相同的方式来实现换挡模式，因此不再详细地描述换挡操作。
图8是根据本发明的各种示例性实施方式的混合动力电动车辆的动力传输装置的示意图。
参照图8，根据各种示例性实施方式的混合动力电动车辆的动力传输装置与图7中各种示例性实施方式的不同之处在于，在输入轴IS与发动机输出轴EOS之间应用单向离合器OWC。
因为单向离合器OWC安装于输入轴IS与发动机输出轴EOS之间，所以可以在EV模式下和再生制动中避免发动机阻力。
因此，根据图8中的各种示例性实施方式的混合动力电动车辆的动力传输装置仅在采用单向离合器的特征上不同于图7中的各种示例性实施方式，而其他布置保持相同，因此不再详细描述其他布置。
另外，仅仅除单向离合器OWC的操作之外，可以以与图3中各种示例性实施方式中的相同的方式来实现换挡模式，因此，将不再详细描述换挡操作。
如上所述，根据示例性实施方式的混合动力电动车辆的动力传输装置仅采用两个行星齿轮组PG1和PG2，从而简化了变速器的结构。另外，可以将分别具有四速的发动机模式和并联混合动力模式与电控无级变速模式(eCVT模式)结合，以实现具有多于六速的各种换挡模式，从而降低生产成本，并且实现高于等效变速器的燃料消耗特性和功率性能。
另外，与传统的六速变速器相比，可以减少所采用的行星齿轮组的数量，因此，可以减少总长度，从而提高可安装性。
另外，在输入轴IS与发动机输出轴EOS之间安装有单向离合器OWC，从而可以在EV模式下和再生制动中避免发动机阻力。
