背景技术

具体实施方式

参考图1至2，本发明的第一和第二实施例共同地包括第一差速齿轮组、第二差速齿轮组、第一电动发电机MG1、第二电动发电机MG2、第一固定机构、第二固定机构、第三扭矩传递装置、第四扭矩传递装置。

第二差速齿轮组包括至少三个旋转部件。这些旋转部件包括连续地连接到第一差速齿轮组的旋转部件的旋转部件，以及两个旋转部件，这两个旋转部件各自连接到输出部件OUTPUT，或选择性地连接到第一差速齿轮组的另一旋转部件，或者既连接到输出部件OUTPUT又选择性地连接到第一差速齿轮组的另一旋转部件。
第一电动发电机MG1连续地连接到第一差速齿轮组的除了连接到发动机ENGINE的旋转部件和选择性地彼此连接的旋转部件以外的旋转部件。
第二电动发电机MG2连续地连接到第二差速齿轮组的连续地连接到第一差速齿轮组的旋转部件的旋转部件。
第一固定机构设置成限制第二行星齿轮组的除了连接到输出部件OUTPUT的旋转部件和连接到第二电动发电机MG2的旋转部件以外的旋转部件的旋转。
第二固定机构设置成限制第一差速齿轮组的与第一电动发电机MG1连接的旋转部件的旋转。
第三扭矩传递装置布置成选择性地连接或分离第二差速齿轮组的旋转部件与第一差速齿轮组的旋转部件。
第四扭矩传递装置布置成选择性地连接或分离第一差速齿轮组的两个旋转部件。
尽管描述在这些实施例中第一差速齿轮组和第二差速齿轮组通过行星齿轮组实现，但是它们也可以通过使至少一个齿轮具有其它两个齿轮的加权平均速度的、使用锥齿轮等的其它类型的齿轮组来实现。
优选地，第一差速齿轮组是拉威那式行星齿轮组并且在下文中被称为第一行星齿轮组1，并且第二差速齿轮组是简单行星齿轮组并且在下文中被称为第二行星齿轮组2。
优选地，第一行星齿轮组1包括第一中心齿轮S1-1、第一中心齿轮S1-2、第一支架C1和第一环形齿轮R1，并且第二行星齿轮组2包括第二中心齿轮S2、第二支架C2和第二环形齿轮R2。
优选地，第一固定机构和第二固定机构分别是可以限制与之连接的旋转部件的旋转的第一制动器BK1和第二制动器BK2，并且第三扭矩传递机构和第四扭矩传递机构是可以选择性地连接和分离可相对旋转的两个旋转部件的第一离合器CL1和第二离合器CL2。
此外，第二离合器CL2布置成选择性地连接和分离第一行星齿轮组1的第一支架C1与第一环形齿轮R1，第一制动器BK1布置成限制第二环形齿轮R2的旋转，并且第二电动发电机MG2连续地连接到第二中心齿轮S2，并且输出部件OUTPUT连接到第二支架C2。
根据图1的第一实施例，发动机ENGINE连接到第一支架C1，第一电动发电机MG1连接到第一中心齿轮S1-1，第一中心齿轮S1-2连续地连接到第二中心齿轮S2，第一离合器CL1布置成选择性地连接第一支架C1与第二环形齿轮R2，并且第二制动器BK2布置成限制第一中心齿轮S1-1的旋转。
另一方面，根据图2的第二实施例，发动机ENGINE连接到第一环形齿轮R1，第一电动发电机MG1连接到第一中心齿轮S1-2，第一中心齿轮S1-1连续地连接到第二中心齿轮S2，第一离合器CL1布置成选择性地连接第一支架C1与第二支架C2，并且第二制动器BK2布置成限制第一中心齿轮S1-2的旋转。
参考图3至11描述根据图1的第一实施例的传动装置的操作。
图3是示出图1的第一实施例的操作模式的表，所述操作模式包括第一EV模式(EV1)、第二EV模式(EV2)、输入分流模式、复合分流模式、第一低速传动固定齿轮比模式(UD1)、第二低速传动固定齿轮比模式(UD2)、1∶1固定齿轮比模式(1∶1)和超速传动固定齿轮比模式(OD)。
图4示出EV1模式。EV1模式通过在发动机ENGINE停止的状态下接合第一制动器BK1来实现。
在该模式中，第二环形齿轮R2由第一制动器BK1固定。因此，当第二电动发电机MG2驱动第二中心齿轮S2时，动力越过第二支架C2得到减小并被输出到与驱动轮连接的输出部件OUTPUT。
在该操作中，第一中心齿轮S1-2与第二中心齿轮S2一起被第二电动发电机MG2驱动，并且发动机ENGINE停止。因此，第一电动发电机MG1通过第一中心齿轮S1-1自由反转。
图5示出EV2模式，其通过接合第一制动器BK1和第一离合器CL1而实现。
通过连接第一离合器CL1，在两个旋转部件被连接的状态下，第一行星齿轮组1和第二行星齿轮组2形成一个直杠杆，如图所示，第二环形齿轮R2、第一支架C1和发动机ENGINE由第一制动器BK1固定，并且第一电动发电机MG1和第二电动发电机MG2在以彼此相反的方向被驱动的同时通过第二支架C2输出动力，如图所示。
因此，第一电动发电机MG1和第二电动发电机MG2能够以比EV1模式更高的效率被驱动，结果，该模式能够提高车辆的燃料效率。
图6示出输入分流模式，其中传动装置作为EVT工作。
在仅接合第一制动器BK1的状态下，通过来自发动机ENGINE的动力和来自第二电动发电机MG2的动力来进行驱动，并且第一电动发电机MG1根据情况产生电力。
图7示出复合分流模式。复合分流模式通过接合第一离合器CL1而实现，其中第一行星齿轮组1和第二行星齿轮组2通过第一离合器CL1而成为一体，如图所示，形成一个杠杆，使得通过第二电动发电机MG2和发动机ENGINE进行驱动并且第一电动发电机MG1根据情况产生电力或使动力循环。
图8示出UD1模式，其通过接合第一制动器BK1和第二离合器CL2而实现。
第一行星齿轮组1通过第二离合器CL2的接合而成为一体，并且第二环形齿轮R2通过第一制动器BK1的接合而被固定，使得发动机ENGINE的动力被供应给第一支架C1并整体地旋转整个第一行星齿轮组1，并且该动力驱动第二行星齿轮组2的第二中心齿轮S2并越过第二支架C2而得到减小、然后被输出。在该操作中，第一电动发电机MG1和第二电动发电机MG2与发动机ENGINE一起自由旋转，其中发动机ENGINE的动力越过第二行星齿轮组2以预定减速齿轮比得到减小、然后被输出。
图9示出UD2模式，其通过接合第一制动器BK1和第二制动器BK2而实现。
由于第一中心齿轮S1-1被固定，所以来自发动机ENGINE的动力通过第一支架C1和第二中心齿轮S1-2被供应到第二行星齿轮组2的第二中心齿轮S2，并且第二中心齿轮S2的动力越过第二支架C2而得到减小、然后被输出。
图10示出1∶1模式，其通过接合第一离合器CL1和第二离合器CL2而实现。在该模式中，第一行星齿轮组1通过第二离合器CL2而成为一体，并且第二行星齿轮组2通过第一离合器CL1与第一行星齿轮组1成为一体。因此，输出到第一支架C1的发动机ENGINE的动力通过第二支架C2不发生改变地输出到输出部件OUTPUT。
相似地，第一电动发电机MG1和第二电动发电机MG2与发动机ENGINE一起自由旋转。
图11示出OD模式，其通过接合第二制动器BK2和第一离合器CL1而实现。
即，第一行星齿轮组1和第二行星齿轮组2通过第一离合器CL1的接合而形成一个杠杆，并且第一中心齿轮S1-1通过第二制动器BK2的接合而被固定。结果，供应到第一支架C1的发动机ENGINE的动力被供应到第二环形齿轮R2，通过第二支架C2得到增大，然后被输出。
同时，图12示出图2的第二实施例的操作模式的表，所述操作模式包括EV1模式、输入分流模式、复合分流模式、UD模式、1∶1模式和OD模式。
EV1模式和输入分流模式通过接合第一制动器BK1而实现，复合分流模式通过接合第一制动器CL1而实现，并且UD模式通过接合第二离合器CL2和第一制动器BK1而实现，并且1∶1模式通过接合第一离合器CL1和第二离合器CL2并使第一行星齿轮组1和第二行星齿轮组2成为一体而实现。此外，OD模式通过接合第一离合器CL1和第二制动器BK2而实现。
该实施例的动力流和操作与图1的第一实施例基本相似，并且省略其描述。
出于例证和说明的目的，已经给出了本发明的具体示例性实施例的上述说明。它们并非意在是无遗漏的或者将本发明限制于所公开的精确形式，并且明显的是，根据上述教导，许多改型和变型都是可能的。选择和说明示例性实施例是为了解释本发明的某些原理和它们的实际应用，从而使本领域技术人员能够做出和利用本发明的各种示例性实施例及其各种替代形式和改型。本发明的范围应该由所附权利要求和它们的等价形式限定。
