具体实施方式
现在将详细参照本发明的各个实施例，各个实施例的示例在附图中示出并且在下面进行描述。尽管将结合本发明的示例性实施例来描述本发明，但是应当理解的是，本说明书不旨在将本发明限制于那些示例性实施例。另一方面，本发明不仅旨在涵盖本发明的示例性实施例，而且旨在涵盖如所附权利要求书所限定的本发明的宗旨和范围内可以包括的各种替代、修改、等同方案和其它实施例。
参照图1，根据本发明的示例性实施例的混合动力总成被配置成包括：发动机输入轴EI，通过主离合器MC连接至发动机E；马达输入轴MI，被安装成与发动机输入轴EI形成同心轴并连接有马达M；中心同步器CS，被安装成使发动机输入轴EI和马达输入轴MI断续；第一输出轴OUT1和第二输出轴OUT2，与发动机输入轴EI平行安装；多个外齿轮对，被安装以在马达输入轴MI与第一输出轴OUT1之间、在发动机输入轴EI与第一输出轴OUT1之间以及在发动机输入轴EI与第二输出轴OUT2之间形成不同的齿轮比；以及锥形离合器CC，安装在第一连接齿轮CG1和中心同步器CS之间，第一连接齿轮CG1可旋转地安装在马达输入轴MI上以构成安装在马达输入轴MI与第一输出轴OUT1之间的外齿轮对中的任何一个，并且由中心同步器CS的套筒驱动，以实现在第一连接齿轮CG1和马达输入轴MI之间传递的扭矩的连续变化。
也就是说，本发明的示例性实施例如下配置：图中右侧的第一变速模块MD1和左侧的第二变速模块MD2可以通过中心同步器CS彼此连接。第一输出轴OUT1被安装成在第一变速模块MD1和第二变速模块MD2两者中共同使用，并且通过第一输出齿轮OG1向差速器DF输出动力，并且第二输出轴OUT2被安装成通过第二输出齿轮OG2向差速器DF输出从第二变速模块MD2传递的动力。
第一输出轴OUT1设置有与第一连接齿轮CG1啮合的第二连接齿轮CG2。
因此，安装在马达输入轴MI和第一输出轴OUT1之间的外齿轮对包括：第一级主动齿轮1D和第一级从动齿轮1P，用于实现一系列变速级之中的第一级；第二级主动齿轮2D和第二级从动齿轮2P，用于实现一系列变速级中的第二级；以及第一连接齿轮CG1和第二连接齿轮CG2。
由第一连接齿轮CG1和第二连接齿轮CG2形成的齿轮比略小于由第二级主动齿轮2D和第二级从动齿轮2P形成的第二级齿轮比。例如，优选地，由第一连接齿轮CG1和第二连接齿轮CG2形成的齿轮比小于第二级齿轮比的0.01至0.05的范围。
此外，第一输出轴OUT1设置有第一离合器模块CLM1，第一离合器模块CLM1具有分别设置在其两侧的被配置成使第一级从动齿轮1P对第一输出轴OUT1断续的同步器和被配置成使第二级从动齿轮2P对第一输出轴OUT1断续的爪形离合器DC。
如果由第一连接齿轮CG1和第二连接齿轮CG2形成的齿轮比略小于由第二级主动齿轮2D和第二级从动齿轮2P形成的第二级齿轮比，则当在第二级驱动状态下，在接合锥形离合器CC的同时释放爪形离合器DC以换挡到另一个变速级而没有扭矩中断时，爪形离合器DC被平稳地释放而不需要冲击或过大的操作力。
如果接合锥形离合器CC，则可以通过如上所述的齿轮比差，从通过第二级主动齿轮2D和第二级从动齿轮2P来将扭矩从马达输入轴MI传递到第一输出轴OUT1的状态转换到通过第一连接齿轮CG1和第二连接齿轮CG2来传递扭矩的状态。此时，如果爪形离合器DC从第二级从动齿轮2P释放，则爪形离合器DC容易被释放。
此外，在第一离合器模块CLM1中，将爪形离合器DC用作用于使第二级从动齿轮2P对第一输出轴OUT1的断续的装置的原因如下：在由第一连接齿轮CG1和第二连接齿轮CG2形成的齿轮比与第二级齿轮比之间存在齿轮比差的情况下，当接合锥形离合器CC并且执行从另一变速级到第二级的换挡，同时消除扭矩中断时，由于齿轮比差，在第一离合器模块CLM1的套筒和第二级从动齿轮2P之间产生较小的相对速度。利用形成同步器的同步器环的容量，难以克服和同步这种相对速度，而甚者，由于相对速度，套筒和第二级从动齿轮2P的离合器齿轮之间的啮合是不可能的。
因此，如上所述，仅在很小的范围内产生齿轮比差，并且产生微小的相对速度，但是在接合锥式离合器CC的状态下几乎同步。因此，优选使第一离合器模块CLM1的套筒按照原样与第二级从动齿轮2P的离合器齿轮啮合。
作为参考，本文中的“同步器”是指包括同步器环的设备，该同步器环被安装在毂和离合器齿轮之间，以在相对于毂沿轴向滑动的套筒与一体地连接到用于形成变速级的变速机齿轮的离合器齿轮啮合时，首先使套筒和离合器齿轮的速度同步，并且“爪形离合器”是指从如上所述的同步器的配置中除去执行同步作用的同步器环的设备。这些配置在本领域中是众所周知的。
在本发明的示例性实施例中，共同配置来实现外齿轮对中的两个外齿轮对的第一共同齿轮CMG1和第二共同齿轮CMG2以旋转被断续的状态设置在发动机输入轴EI上，并且第一共同齿轮CMG1一体地设置有与中心同步器CS的套筒啮合的离合器齿轮。
因此，当中心同步器CS使套筒与第一共同齿轮CMG1的离合器齿轮啮合时，马达输入轴MI和发动机输入轴EI连接在一起。
第一共同齿轮CMG1与第一输出轴OUT1的第六级从动齿轮6P啮合以形成外齿轮对，并且同时与第二输出轴OUT2的第四级从动齿轮4P啮合以形成外齿轮对。
此外，第二共同齿轮CMG2与第一输出轴OUT1的第五级从动齿轮5P啮合以形成外齿轮对，并且同时与第二输出轴OUT2的第三级从动齿轮3P啮合以形成外齿轮对。
因此，可以通过使用相对少量的齿轮来构成换档所需的外齿轮对。
第二离合器模块CLM2设置在第一输出轴OUT1的第五级从动齿轮5P和第六级从动齿轮6P之间，第二离合器模块CLM2具有分别设置在其两侧的被配置成使第五级从动齿轮5P对第一输出轴OUT1断续的同步器和被配置成使第六级从动齿轮6P对第一输出轴OUT1断续的同步器。
因此，第五级或第六级可以通过移动第二离合器模块CLM2的套筒来实现。
第三离合器模块CLM3设置在第二输出轴OUT2的第三级从动齿轮3P和第四级从动齿轮4P之间，第三离合器模块CLM3具有分别设置在其两侧的被配置成使第三级从动齿轮3P对第二输出轴OUT2断续的同步器和被配置成使第四级从动齿轮4P对第二输出轴OUT2断续的同步器。
因此，可以通过移动第三离合器模块CLM3的套筒来实现第三级或第四级。
同时，安装在马达输入轴MI与第一输出轴OUT1之间的外齿轮对用于实现待被实现的一系列变速级之中依次具有最大齿轮比的两个齿轮比。
也就是说，安装在马达输入轴MI与第一输出轴OUT1之间的外齿轮对用于实现第一级齿轮比和第二级齿轮比。
如上所述的本发明可以表示如下。
也就是说，根据本发明的示例性实施例的混合动力总成被配置为包括：第一变速模块MD1，包括直接连接有马达M的马达输入轴MI，并且被设置为形成一系列变速级之中依次具有最大齿轮比的两个变速级；第二变速模块MD2，包括与马达输入轴MI形成同心轴并通过主离合器MC连接到发动机E的发动机输入轴EI，并被设置为形成一系列变速级的剩余变速级；中心同步器CS，被安装以使马达输入轴MI和发动机输入轴EI断续；以及连续可变装置，被设置为通过连续控制的摩擦力来实现第一变速模块MD1形成比第一变速模块MD1的变速级之中具有小齿轮比的变速级更小的齿轮比的状态。
这里，连续可变装置CHD被配置成使得通过中心同步器CS的套筒来连续地控制摩擦力。
同时，第一变速模块MD1被配置成包括：第一输出轴OUT1，与马达输入轴MI平行安装；第一级主动齿轮1D和第一级从动齿轮1P，第一级主动齿轮1D安装在马达输入轴MI上，第一级从动齿轮1P安装在第一输出轴OUT1上，以实现第一级；第二级主动齿轮2D和第二级从动齿轮2P，第二级主动齿轮2D安装在马达输入轴MI上，第二级从动齿轮2P安装在第一输出轴OUT1上，以实现第二级；以及第一离合器模块CLM1，具有分别设置在其两侧的被配置成使第一级从动齿轮1P对第一输出轴OUT1断续的同步器和被配置成使第二级从动齿轮2P对第一输出轴OUT1断续的爪形离合器DC。
这里，连续可变装置CHD被配置成包括：第一连接齿轮CG1，可旋转地安装在马达输入轴MI上；第二连接齿轮CG2，安装在第一输出轴OUT1上使得其旋转被断续；以及锥形离合器CC，被设置成由中心同步器CS的套筒驱动，并且通过连续控制的摩擦力来实现在第一连接齿轮CG1和马达输入轴MI之间传递的扭矩的连续变化。
同时，图22示出根据本发明的示例性实施例的混合动力总成的第二示例性实施例。这里，其它配置与图1相同，并且第二示例性实施例具有如下配置：马达M被安装成通过与马达输入轴MI的第二级主动齿轮2D啮合的减速主动齿轮(RD)将动力传递到马达输入轴MI。
减速主动齿轮RD也可以被安装成与第一级主动齿轮1D啮合。
图23示出根据本发明的示例性实施例的混合动力总成的第三示例性实施例。这里，其它配置与图1相同，并且第三示例性实施例具以下配置：在马达M和马达输入轴MI之间设置有行星齿轮PG，该行星齿轮PG减小马达M的动力并将减小的动力传递至马达输入轴MI。
在本发明的图22和图23的两个示例性实施例中，马达M的动力被减小并将被提供给马达输入轴MI，从而可以相对减小马达M的容量。
图2A-2C、图3A-3C和图4A-4B是顺序示出图1的动力总成执行从第一级到第二级的上电升档的视图。将描述该过程。
作为参考，动力作用的部分由粗线表示。
图2A示出以下状态：发动机的动力驱动发动机输入轴EI以及通过中心同步器CS一起驱动马达输入轴MI，第一离合器模块的同步器形成第一级，马达输入轴MI的动力通过第一级主动齿轮1D和第一级从动齿轮1P被传递至第一输出轴OUT1，并且通过第一输出齿轮OG1被引出至差速器DF。
图2B示出当发生从图2A的状态到第二级的换挡指令时一起驱动马达M的状态。
图2C示出在继续通过马达M执行第一级驱动的同时释放主离合器MC并接合锥形离合器CC的状态。由于中心同步器CS的套筒操作锥形离合器CC，所以中心同步器CS自然地释放，以将发动机输入轴EI和马达输入轴MI分离。
图3A示出第一离合器模块的同步器释放第一级的状态。这里，通过锥形离合器CC、第一连接齿轮CG1和第二连接齿轮CG2将动力连续地传递到第一输出轴OUT1，从而防止扭矩中断。
图3B示出第一离合器模块的爪形离合器DC的接合。如上所述，在通过锥式离合器CC传递动力的图3A的状态下，由于第一连接齿轮CG1与第二连接齿轮CG2的齿轮比与第二级齿轮比之间的齿轮比差而在第二级从动齿轮2P与第一离合器模块的套筒之间产生微小的相对速度，因此，第一离合器模块的套筒通过使用不具有同步器环的爪形离合器DC与第二级从动齿轮2P的离合器齿轮啮合。
图3C示出锥形离合器CC被释放并且由马达M执行两速驱动的状态。
图4A示出以下状态：中心同步器CS被接合以连接发动机输入轴EI和马达输入轴MI，然后主离合器MC被接合以将发动机的动力和马达M的动力两者传递至第一输出轴OUT1，执行两速驱动。
图4B示出在图4A的状态下马达M不产生动力从而由发动机执行两速驱动的状态。
图5A-5C和图6A-6B是顺序示出图1的动力总成执行从第二级到第三级的上电升档的视图。将描述该过程。
图5A示出由发动机执行两速驱动的状态。在该状态下，当发生向三速的换挡指令时，如图5B中所示，在一起驱动马达M的同时形成两速驱动状态。
图5C示出通过释放主离合器MC和中心同步器CS使发动机输入轴EI与马达输入轴MI分离的状态。这里，两速驱动状态仍然由车辆的马达M形成。
图6A示出以下情况：通过由第三离合器模块CLM3的同步器将第三从动齿轮连接至第二输出轴OUT2并联接主离合器MC而由发动机执行三速驱动，并且马达M的动力也被传递到差速器DF。
图6B示出在图6A的状态下通过释放马达M的动力而仅由发动机形成三速驱动状态的情况。
如上所述，即使当执行从第二级到第三级的换挡时，也不会发生扭矩中断。
图7A-7C和图8A-8B是顺序示出图1的动力总成执行从第三级到第四级的上电升档的视图。在下文中，将对此进行描述。
图7A中的状态为仅通过发动机的动力执行三速驱动的状态。当发生向第四级的换档指令时，如图7B所示，马达M被驱动，以使马达M的动力被传递到差速器DF。
图7C示出通过释放主离合器MC而仅由马达M执行三速驱动的状态。
图8A示出以下情况：通过由第三离合器模块CLM3的同步器将第四从动齿轮连接至第二输出轴OUT2并联接主离合器MC而由发动机执行四速驱动并且马达M的动力也被传递到差速器DF。
图8B示出在图8A的状态下通过释放马达M的动力而仅由发动机形成四速驱动状态的情况。
如上所述，即使在当前的换挡过程中也不会发生扭矩中断。原因是在马达M通过第二主动齿轮和第二从动齿轮传递动力时，主离合器MC被释放并且第三离合器模块CLM3可以被切换以将第四级从动齿轮4P连接到第二输出轴OUT2，而不是第三级从动齿轮3P。
此时，根据每个变速级的速度来调节马达M的速度。
图9A-9C和图10A-10B是顺序示出图1的动力总成执行从第四级到第五级的上电升档的视图。在这里，唯一的区别是由第三离合器模块CLM3的同步器释放第四级，并且由第二离合器模块CLM2的同步器接合第五级，其余与从第三级到第四级的换挡相同。因此，省略详细描述。
图11A-11C和图12A-12B是顺序示出图1的动力总成执行从第五级到第六级的加电升档的视图。这里，唯一的区别是由第二离合器模块CLM2的同步器释放第五级并接合第六级，其余与从第三级到第四级的换档相同。因此，省略详细描述。
图13A-13C和图14A-14B是顺序示出图1的动力总成执行从第三级到第二级的上电降档的视图。将对此进行描述。
图13A示出发动机的三速驱动状态。当发生向两速的换档指令时，如图13B所示，马达M被驱动，从而通过马达还将三速动力提供给第一输出轴OUT1。
图13C示出通过释放主离合器MC并且将第三离合器模块CLM3的同步器释放到空档而仅由马达M驱动车辆的状态。这里，通过调节马达M的速度来使车辆在两速状态下行驶。
图14A示出通过接合中心同步器CS后联接主离合器MC将发动机的动力也通过第一输出轴OUT1传递至差速器DF的状态。
图14B示出通过释放马达M的动力而仅通过由发动机实现两速驱动状态的状态。
如上所述，即使在上述换挡过程中也不会发生扭矩中断。
图15A-15C、图16A-16B和图17A-17B是顺序示出图1的动力总成执行从第二级到第一级的上电降档的视图。将对此进行描述。
图15A示出发动机的两速驱动状态。当发生向单速的换挡指令时，如图15B所示，驱动马达M，从而通过发动机和马来达M实现单速。
图15C示出在释放主离合器MC并且释放中心同步器CS之后发生锥形离合器CC的摩擦的状态。如上所述，由于第一连接齿轮CG1和第二连接齿轮CG2的齿轮比被配置成略微小于第二级齿轮比，所以当锥形离合器CC被接合时，状态从通过第二级主动齿轮2D和第二级从动齿轮2P来将马达M的动力传递到第一输出轴OUT1的状态改变为通过第一连接齿轮CG1和第二连接齿轮CG2来传递马达M的动力的状态。因此，可以容易地从第二级从动齿轮2P释放爪形离合器DC。
图16A示出如上所述地释放第一离合器模块CLM1的爪形离合器DC的状态。
如果第一连接齿轮CG1和第二连接齿轮CG2的齿轮比与第二级齿轮比相同或被设置为大于第二级齿轮比，则不容易进行释放爪形离合器DC，并且即使释放爪形离合器DC，也会产生冲击或噪音，这是因为即使如上当接合所述锥式离合器CC时，也保持仍然通过第二级从动齿轮2P传递动力的状态。
图16B示出马达M的速度被调节为单速并且第一级从动齿轮1P通过第一离合器模块CLM1的同步器连接到第一输出轴OUT1的状态。
图17A示出以下状态：通过释放锥形离合器CC，接合中心同步器CS，并且然后接合主离合器MC，通过第一级主动齿轮1D和第一级从动齿轮1P将发动机的动力提供至第一输出轴OUT1。
图17B示出通过释放马达M的动力而仅由发动机形成单速驱动状态的情况。这里，在没有扭矩中断的情况下完成换挡。
图18A-18C和图19A-19B是顺序示出图1的动力总成在电动车辆模式下执行从第一级到第二级的上电升档的视图。将对此进行描述。
如图18A所示，在仅通过马达M驱动的电动车辆模式的第一级驱动状态下，当发生向第二级的换档指令时，如图18B所示，锥形离合器CC产生摩擦力，并且如图18C所示，释放第一离合器模块CLM1的同步器，从而释放第一级从动齿轮1P和第一输出轴OUT1之间的连接状态。
图19A示出通过移动第一离合器模块CLM1的套筒以接合爪形离合器DC而将第二级从动齿轮2P连接至第一输出轴OUT1的状态。
图19B示出以下状态：通过释放锥形离合器CC使得仅通过第二级主动齿轮2D和第二级从动齿轮2P来将马达M的动力传递至第一输出轴OUT1，从而执行电动车辆模式的两速驱动。
还可以看出，在该换挡过程中不会发生扭矩中断。
图20A-20C和图21A-21B是顺序示出图1的动力总成在电动车辆模式下执行从第二级到第一级的上电降档的视图。将对此进行描述。
如图20A所示，在仅通过马达M驱动的电动车辆模式的第二级驱动状态下，当发生向第一级的换档指令时，如图20B所示，锥形离合器CC产生摩擦力，并且如图20C所示，释放爪形离合器DC。
图21A示出通过将马达M的速度调节为单速然后接合第一离合器模块CLM1的同步器来将第一级从动齿轮1P连接至第一输出轴OUT1的状态。
图21B示出以下状态：通过释放锥形离合器CC，仅通过第一级主动齿轮1D和第一级从动齿轮1P来将马达M的动力传递至第一输出轴OUT1，从而形成单速。还可以看出，在没有扭矩中断的情况下完成了换档。
根据如上所述的本发明的示例性实施例，可以通过解决作为AMT的缺点的扭矩中断来改善变速感，同时通过使用马达M，利用了诸如成本、材料成本和燃料效率的AMT的优点。因为可以去除传统的在马达M位于发动机和变速器之间的混合动力总成中通常需要的马达和发动机之间的离合器，从而不仅可以通过减小变速器的总体长度而改善车辆的可安装性，而且降低重量和成本。
根据本发明的示例性实施例，可以通过解决作为AMT的缺点的扭矩中断来改善变速感，同时通过利用马达而利用AMT的优点。因为可以去除在马达位于发动机和变速器之间的混合动力总成中通常需要的马达和发动机之间的离合器，从而不仅可以通过减小变速器的总体长度而改善车辆的可安装性，而且降低重量和成本，并且可以进一步有助于提高车辆的燃料效率。
