具体实施方式
本领域一般技术人员将认识到，诸如“上面”、“下面”、“向上”、“向下”、“顶部”、“底部”等术语是描述性地用于图式，并且并不表示对如由所附权利要求书限定的本公开的范围的禁止。另外，本教导在本文可以依据功能和/或逻辑块部件和/或各个处理步骤来描述。应当意识到，这些块部件可以包括配置成执行指定功能的任何数量的硬件、软件和/或固件部件。
参考图式，其中相同数字指示全部几个视图的相同部分，总体上以20示出变速器。变速器20用于车辆。车辆可以包括(但不限于)卡车、火车、拖拉机或某种其他形式的车辆。变速器20是动力系的部分。动力系可以包括混合动力系，其包括发动机22(例如，内燃机22)和一对电动装置。
参考图1，变速器20总体上被表示为杠杆图。下文参考图1对变速器20的描述适用于图2至6中所示的变速器20的不同实施例。图2至6示出了总体上由图1的杠杆图表示的变速器20的不同实施例和每个实施例的具体应用的符号图。
参考图1，变速器20包括输入构件24。如果动力系配备有发动机22，那么输入构件24可以联接至发动机22。如上文所提及，发动机22可以包括(但不限于)内燃机22，诸如汽油或柴油发动机22。发动机22可选择性地操作以产生施用至输入构件24的转矩。因此，输入构件24从发动机22接收转矩。发动机22的具体类型和配置以及发动机22的操作与本公开的教导有关，并且因此不会在本文进行详述。
变速器20可以配备有输入制动器26。输入制动器26可选择性地操作以将输入构件24接地。输入制动器26可以包括例如输入离合器28，其可选择性地操作以将输入构件24与固定构件30接合以防止或阻止输入构件24旋转。固定构件30可以包括例如变速器20的壳体或变速器20的某些其他固定结构。因而，当输入离合器28接合时，输入制动器26防止或限制输入构件24相对于固定构件30旋转，并且当输入离合器28脱离时，输入制动器26允许输入构件24相对于固定构件30旋转。输入制动器26可以接合和/或脱离以在其中发动机22和一个或多个电动装置用于为车辆供电的混合动力操作与当仅将使用电动装置为车辆供电的全电动模式之间切换。
变速器20进一步包括输出构件32。输出构件32联接至动力系的最终驱动系统34。最终驱动系统34可以包括但不限于驱动轴、差速器、齿轮减速系统、车轴、一个或多个车轮等。输出构件32将转矩从变速器20传输或输出至最终驱动系统34。最终驱动系统34的具体类型和配置以及最终驱动系统34的操作与本公开的教导无关，并且因此不会在本文进行详述。
变速器20进一步包括第一电动装置36和第二电动装置38。第一电动装置36和第二电动装置38中的每一个可以包括但不限于电动马达或电动马达/发电机。应当明白的是，第一电动装置36和第二电动装置38可以包括除本文所述的电动马达或电动马达/发电机之外的装置。另外，第一电动装置36和第二电动装置38这二者均可以包括电动马达，或均可以包括电动马达/发电机。替代地，应当明白的是，第一电动装置36和第二电动装置38中的一个可以包括电动马达或某个其他装置，且第一电动装置36和第二电动装置38中的另一个可以包括电动马达/发电机或某个其他装置。
变速器20包括联接至第一电动装置36的第一行星齿轮组40。第一行星齿轮组40包括第一太阳齿轮42、第一环形齿轮44和附接至第一行星架46的多个第一行星齿轮。如本领域中已知的，第一太阳齿轮42与中心轴线同心。第一行星齿轮设置成与第一太阳齿轮42啮合接合，并且各自由第一行星架46支撑或承载。第一环形齿轮44围绕第一行星齿轮并且设置成与第一行星齿轮啮合接合。
第一电动装置36连接至第一太阳齿轮42、第一环形齿轮44和第一行星架46中的一个。如在此详细描述中所使用，术语“连接”被限定为以提供直接、一对一旋转连接且其间的转速和/或转矩没有任何增加或减小的方式联接。如本文所使用，术语“连接”包括第一装置直接连接至第二装置，其间没有中间部件，并且还包括第一装置间接连接至第二装置，其中一个或多个部件设置在第一装置与第二装置之间。然而，只要不改变第一装置与第二装置的转速和转矩，第一装置就连接至第二装置。如图中所示并且如本文所述，第一电动装置36连接至第一太阳齿轮42。然而，应当明白的是，第一电动装置36可以替代地连接至第一环形齿轮44或第一行星架46。
变速器20包括联接至第二电动装置38的第二行星齿轮组48。第二行星齿轮组48包括第二太阳齿轮50、第二环形齿轮52和附接至第二行星架54的多个第二行星齿轮。如本领域中众所周知，第二太阳齿轮50与中心轴线同心。第二行星齿轮设置成与第二太阳齿轮50啮合接合，并且各自由第二行星架54支撑或承载。第二环形齿轮52围绕第二行星齿轮并且设置成与第二行星齿轮啮合接合。
第二电动装置38连接至第二太阳齿轮50、第二环形齿轮52和第二行星架54中的一个。如图中所示并且如本文所述，第二电动装置38连接至第二太阳齿轮50。然而，应当明白的是，第二电动装置38可以替代地连接至第二环形齿轮52或第二行星架54。
该输出联接至第一行星齿轮组40和第二行星齿轮组48这二者。该输出连接至第一太阳齿轮42、第一环形齿轮44和第一行星架46中的一个。如图中所示并且如本文所述，该输出连接至第一环形齿轮44。然而，应当明白的是，该输出可以替代地连接至第一太阳齿轮42或第一行星架46。该输出还连接至第二太阳齿轮50、第二环形齿轮52和第二行星架54中的一个。如图中所示并且如本文所述，该输出连接至第二行星架54。然而，应当明白的是，该输出可以替代地连接至第二太阳齿轮50或第二环形齿轮52。
该输入连接至第一行星齿轮组40。如图中所示并且如本文所述，该输入连接至第一太阳齿轮42、第一环形齿轮44和第一行星架46中的一个。更具体地，该输入连接至第一行星架46。然而，应当明白的是，该输入可以替代地连接至第一太阳齿轮42或第一环形齿轮44。
因此，关于第一行星齿轮组40，该输入连接至第一太阳齿轮42、第一环形齿轮44和第一行星架46中的一个。该输出连接至第一太阳齿轮42、第一环形齿轮44和第一行星架46中的另一个，且第一电动装置36连接至第一太阳齿轮42、第一环形齿轮44和第一行星架46中的又一个。应当明白的是，第一太阳齿轮42、第一行星架46和第一环形齿轮44各自限定第一行星齿轮组40的相应节点，且该输入、该输出和该第一电动装置36各自连接至第一行星齿轮组40的相应节点。因此，该输入、该输出和该第一电动装置36中的仅一个可以连接至第一行星齿轮组40的任何单个节点。因而，如果第一电动装置36连接至第一太阳齿轮42，那么输入和输出也可以不连接至第一太阳齿轮42。类似地，如果输入连接至第一行星架46，那么输出和第一电动装置36也可以不连接至第一行星架46。另外，如果输出连接至第一环形齿轮44，那么第一电动装置36和输入也可以不连接至第一环形齿轮44。如图中所示和本文所述，第一电动装置36连接至第一太阳齿轮42，输入连接至第一行星架46，且输出连接至第一环形齿轮44。
固定比齿轮减速系统56联接输入和第二行星齿轮组48。该固定比齿轮减速系统56可操作地以减小的转速和增大的转矩将旋转从输入传输至第二行星齿轮组48。优选地，固定比齿轮减速系统56提供3∶1与6∶1之间的齿轮减速比。更优选地，固定比齿轮减速系统56的齿轮减速比在4∶1与5∶1之间。如图中所示并且如本文所述，固定比齿轮减速系统56连接至第二环形齿轮52。
关于第二行星齿轮组48，固定比齿轮减速系统56连接至第二太阳齿轮50、第二环形齿轮52和第二行星架54中的一个。该输出连接至第二太阳齿轮50、第二环形齿轮52和第二行星架54中的另一个，且该第二电动装置38连接至第二太阳齿轮50、第二环形齿轮52和第二行星架54中的又一个。应当明白的是，第二太阳齿轮50、第二行星架54和第二环形齿轮52各自限定第二行星齿轮组48的相应节点，且固定比齿轮减速系统56、输出和第二电动装置38各自连接至第二行星齿轮组48的相应节点。因此，固定比齿轮减速系统56、输出和第二电动装置38中的仅一个可以连接至第二行星齿轮组48的任何单个节点。因而，如果第二电动装置38连接至第二太阳齿轮50，那么固定比齿轮减速系统56和输出也可以不连接至第二太阳齿轮50。类似地，如果固定比齿轮减速系统56连接至第二环形齿轮52，那么输出和第二电动装置38也可以不连接至第二环形齿轮52。另外，如果输出连接至第二行星架54，那么第二电动装置38和固定比齿轮减速系统56也可以不连接至第二行星架54。如图中所示并且如本文所述，第二电动装置38连接至第二太阳齿轮50。固定比齿轮减速系统56可以连接至第二环形齿轮52，或可以替代地连接至第二行星架54。输出可以连接至第二行星架54，或可以替代地连接至第二环形齿轮52。
参考图2和3，变速器60的第一实施例总体上以60示出。变速器60的第一实施例包括实施为具有固定齿轮的偏移中间轴64的固定比齿轮减速系统56。图2示出了配置成在前轮驱动应用中使用的变速器60的第一实施例，而图3示出了配置成在后轮驱动应用中使用的变速器60的第一实施例。在变速器60的第一实施例的整个描述中，上文参考图1描述的各种部件的附图标记也用于表示图2和3所示的变速器60的第一实施例中的对应部件。除非另有提及，否则上文参考图1对变速器20的描述(包括各种部件之间的连接的描述)可适用于图2和3中所示的变速器60的第一实施例。
参考图2和3，固定比齿轮减速系统56包括连接至输入的惰转齿轮62。图2示出了直接连接至输入的惰转齿轮62，而图3示出了经由第一行星架46间接连接至输入的惰转齿轮62。固定比齿轮减速系统56进一步包括具有第一固定齿轮66和第二固定齿轮68的中间轴64。第一固定齿轮66设置成与惰转齿轮62啮合接合。第二固定齿轮68联接至第二行星齿轮组48。更具体地，第二固定齿轮68设置成与第二环形齿轮52啮合接合。第一固定齿轮66和第二固定齿轮68均固定至中间轴64并且可随着中间轴64一起旋转。参考图2，第一环形齿轮44连接至第二行星架54，其进而又连接至输出。参考图3，第一环形齿轮44和第二行星架54均彼此连接，并且连接至输出。
参考图4至6，变速器70的第二实施例总体上示为70。变速器70的第二实施例包括实施为第三行星齿轮组72的固定比齿轮减速系统56。图4示出了配置成在前轮驱动应用中使用的变速器70的第二实施例，图5示出了配置成在后轮驱动应用中使用的变速器70的第二实施例，且图6示出了配置成在重型后轮驱动应用中使用的变速器的第二实施例70。在变速器70的第二实施例的整个描述中，上文参考图1描述的各种部件的附图标记也用于表示图4至6中所示的变速器70的第二实施例中的对应部件。除非另有提及，否则上文参考图1对变速器20的描述(包括各种部件之间的连接的描述)可适用于图4至6中所示的变速器70的第二实施例。
参考图4和5，固定比齿轮减速系统56包括第三行星齿轮组72。第三行星齿轮组72包括第三太阳齿轮74、第三环形齿轮76和附接至第三行星架78的多个第三行星齿轮。如本领域中众所周知，第三太阳齿轮74与中心轴线同心。第三行星齿轮设置成与第三太阳齿轮74啮合接合，并且各自由第三行星架78支撑或承载。第三环形齿轮76围绕第三行星齿轮并且设置成与第三行星齿轮啮合接合。
第三环形齿轮76接地至固定构件30。固定构件30可以包括但不限于变速器20的壳体或防止第三环形齿轮76进行相对旋转的某个其他特征。输入连接至第三太阳齿轮74。第三行星架78联接至第二行星齿轮组48。参考图4，第三行星架78连接至第二环形齿轮52，且第二行星架54连接至输出。参考图5，第三行星架78被示为优选地以实线连接至第二环形齿轮52，且第二行星架54以实线连接至输出。如图5中所示，替代设置示出了以第三行星架78虚线连接至第二行星架54，且第二环形齿轮52以虚线连接至输出。
参考图6，总体上示出了变速器70的第二实施例的专门应用。与图4和5中所示的应用一样，图6中所示的变速器70的第二实施例的应用包括实施为第三行星齿轮组72的固定比齿轮减速系统56。然而，图6中所示的应用包括复合行星齿轮组。复合行星齿轮组提供了使得变速器70能够进行倒挡的第四节点。图6中所示的复合行星齿轮组包括两个环形齿轮(即，分别为第四环形齿轮80和第五环形齿轮82)、两个行星架(即，分别为支撑多个第四行星齿轮的第四行星架84和支撑多个第五行星齿轮的第五行星架86)以及第四太阳齿轮88。第四行星齿轮和第五行星齿轮这二者均设置成与第四太阳齿轮88啮合接合。第四环形齿轮80设置成与第四行星齿轮啮合接合。第五环形齿轮82设置成与第五行星齿轮啮合接合。
第一齿轮减速制动器90选择性地将第四行星架84联接至固定构件30，诸如但不限于变速器70的壳体。第一齿轮减速制动器90可以选择性地与第一齿轮减速离合器94接合和脱离，以分别防止或允许第四行星架84相对于固定构件30旋转。因此，当第一齿轮减速离合器94接合时，第一齿轮减速制动器90防止或限制第四行星架84相对于固定构件30旋转，并且当第一减速离合器94脱离时，第一齿轮减速制动器90允许第四行星架84相对于固定构件30旋转。
第二齿轮减速制动器92将第五环形齿轮82联接至固定构件30，诸如但不限于变速器70的壳体。第二齿轮减速制动器92可以选择性地与第二齿轮减速离合器96接合和脱离，以分别防止或允许第五环形齿轮82相对于固定构件30旋转。因此，当第二齿轮减速离合器96接合时，第二齿轮减速制动器92防止或限制第五环形齿轮82相对于固定构件30旋转，并且当第二减速离合器96脱离时，第二齿轮减速制动器92允许第五环形齿轮82相对于固定构件30旋转。
第四环形齿轮80连接至第五行星架86。第五行星架86连接至第二环形齿轮52。第一齿轮减速制动器90和第二齿轮减速制动器92可以各自独立地接合和/或脱离以提供变速器70的倒挡。例如，当第一齿轮减速制动器90脱离以允许第四行星架84相对于固定构件30旋转且第二齿轮减速制动器92接合以防止第五环形齿轮82相对于固定构件30旋转时，变速器70可以前进挡操作。替代地，当第一齿轮减速制动器90接合以防止第四行星架84相对于固定构件30旋转且第二齿轮减速制动器92脱离以允许第五环形齿轮82相对于固定构件30旋转时，变速器70可以倒挡操作。
第一齿轮减速制动器90和第二齿轮减速制动器92可以各自同时接合以将输入构件24接地，以防止或阻止输入构件24旋转。因而，第一齿轮减速制动器90和第二齿轮减速制动器92可以同时接合以在其中发动机22和一个或多个电动装置用于为车辆供电的混合动力操作与当仅电动装置用于为车辆供电的全电动模式之间切换。
参考图7，变速器的第三实施例总体上示为100。类似于图6中所示的变速器的第二实施例，图7中所示的变速器100的第三实施例包括实施为第三行星齿轮组72的固定比齿轮减速系统56。然而，图7中所示的应用包括堆叠式行星齿轮组。堆叠式行星齿轮组提供了使得变速器100能够进行倒挡的第四节点。图7中所示的堆叠式行星齿轮组包括第六太阳齿轮102、支撑多个第六行星齿轮的第六行星架104、组合式太阳/环形齿轮106、支撑多个第七行星齿轮的第七行星架108以及第七环形齿轮110。第六太阳齿轮102与第六行星架104的第六行星齿轮设置成啮合接合。第六行星架104的第六行星齿轮与组合式太阳/环形齿轮106设置成啮合接合。组合式太阳/环形齿轮106与第七行星架108的第七行星齿轮设置成啮合接合。第七行星架108的第七行星齿轮与第七环形齿轮110设置成啮合接合。
第一齿轮减速制动器90选择性地将组合式太阳/环形齿轮106联接至固定构件30，诸如但不限于变速器100的壳体。第一齿轮减速制动器90可以选择性地与第一齿轮减速离合器94接合和脱离，以防止或允许组合式太阳/环形齿轮106相对于固定构件30旋转。因此，当第一齿轮减速离合器94接合时，第一齿轮减速制动器90防止或限制组合式太阳/环形齿轮106相对于固定构件30旋转，并且当第一减速离合器94脱离时，第一齿轮减速制动器90允许组合式太阳/环形齿轮106相对于固定构件30旋转。
第二齿轮减速制动器92将第七环形齿轮110联接至固定构件30，诸如但不限于变速器100的壳体。第二齿轮减速制动器92可以选择性地与第二齿轮减速离合器96接合和脱离，以分别防止或允许第七环形齿轮110相对于固定构件30旋转。因此，当第二齿轮减速离合器96接合时，第二齿轮减速制动器92防止或限制第七环形齿轮110相对于固定构件30旋转，并且当第二减速离合器96脱离时，第二齿轮减速制动器92允许第七环形齿轮110相对于固定构件30旋转。
第一环形齿轮44连接至第六太阳齿轮102。第六行星架104和第七行星架108同时连接至第二环形齿轮52。第一齿轮减速制动器90和第二齿轮减速制动器92可以各自独立地接合和/或脱离以对变速器100提供倒挡。例如，当第一齿轮减速制动器90脱离以允许组合式太阳/环形齿轮106相对于固定构件30旋转且第二齿轮减速制动器92接合以防止第七环形齿轮110相对于固定构件30旋转时，变速器100可以倒挡操作。替代地，当第一齿轮减速制动器90接合以防止组合式太阳/环形齿轮106相对于固定构件30旋转且第二齿轮减速制动器92脱离以允许第七环形齿轮110相对于固定构件30旋转时，变速器100可以前进挡操作。
第一齿轮减速制动器90和第二齿轮减速制动器92可以各自同时接合以将输入构件24接地，以防止或阻止输入构件24旋转。因而，第一齿轮减速制动器90和第二齿轮减速制动器92可以同时接合以在其中发动机22和一个或多个电动装置用于为车辆供电的混合动力操作与当仅电动装置用于为车辆供电的全电动模式之间切换。
详述和图式或图支持并且描述本公开，但是本公开的范围仅仅是由权利要求书限定。虽然已详细描述了用于实行所述教导的某些最佳模式和其他实施例，但是也存在用于实践所附权利要求书中限定的本公开的各种替代设计和实施例。
