用于汽车的混合驱动装置
技术领域
本发明涉及一种用于汽车的混合驱动装置，其元件至少区段性地包含在壳体内。
背景技术
本领域技术人员已知形式为功率分流变速器的混合驱动装置的多种设计方案。这种驱动装置设置在与驱动轴相连的内燃机和与从动轴相连的汽车从动机构之间，所述驱动装置包括第一电机，其通常设计为内转子电机，即具有位于内部的转子和位于外部的相对壳体固定的定子，所述第一电机既能够在电动机运行模式下运行，也能在发电机运行模式下运行。一般可以是指电动机/发电机单元。然而出于建明阐述的目的，在本发明的范围内主要是指电机，但本发明并不局限于此。已知驱动装置的电机通过功率电子器件既在彼此之间也与电能存储器(尤其是蓄电池)相连。此外，已知的混合驱动装置还包括两个行星齿轮变速器，它们分别具有太阳轮、齿圈以及与太阳轮和齿圈啮合的可旋转地安装在行星架上的一组行星齿轮。此外已知的是，设有多个切换元件或通断元件，各个前述元件通过切换元件彼此耦连或者与壳体耦连。“耦连”在本说明书的范围内理解为可在传递扭矩和不传递扭矩的状态之间切换的连接。与之相对，表述“固定相连”在这种上下文关系中表示不可切换的传递扭矩的连接。
根据混合驱动装置的拓扑结构或布局，可以实现不同数量和类型的运行模式。尤其能够实现驱动轴和从动轴之间的固定转速传动比(挡位)、通过调整一个或两个电机的转速和/或扭矩实现在功率分流运行模式中可连续调节的转速传动比以及纯电动运行模式。
由WO2010/113537A1已知一种驱动装置，其具有两个功率分流运行模式，即纯电动运行模式和超速传动范围内的固定挡位(驱动轴和从动轴之间的传动比小于1)。然而，该装置需要三组行星齿轮并且不允许从某一功率分流模式转速同步地过渡为另一功率分流模式。
技术问题
本发明所要解决的技术问题在于，为前述类型的混合驱动装置建议一种变速器拓扑结构或布局，其允许在只使用两组行星齿轮的情况下，在超速传动范围内可以转速同步地在两个功率分流运行模式之间切换。
发明内容
该技术问题按本发明通过权利要求1的特征解决，即通过一种用于汽车的混合驱动装置解决，其包括壳体并且在壳体中至少区段性地含有：
-输入侧的驱动轴，
-输出侧的从动轴，
-具有相对壳体固定的外部定子和内部转子的第一电机，
-具有相对壳体固定的外部定子和内部转子的第二电机，
-第一行星齿轮变速器，所述第一行星齿轮变速器包括齿圈、太阳轮以及与齿圈和太阳轮啮合的可旋转地安装在行星架上的一组行星齿轮，其中，第一行星齿轮变速器的齿圈与从动轴固定相连，并且第一行星齿轮变速器的太阳轮与第一电机的转子固定相连，
-第二行星齿轮变速器，所述第二行星齿轮变速器包括齿圈、太阳轮以及与齿圈和太阳轮啮合的可旋转地安装在行星架上的一组行星齿轮，其中，第二行星齿轮变速器的齿圈与第二电机的转子固定相连，并且第二行星齿轮变速器的行星架与驱动轴固定相连，
其中，
-第二行星齿轮变速器的太阳轮借助第一制动器与壳体耦连，
-第一行星齿轮变速器的行星架借助第二制动器与壳体耦连，并且
-第一行星齿轮变速器的齿圈借助第一离合器与第二行星齿轮变速器的齿圈耦连。
所述第一和/或第二电机优选与驱动轴共轴地布置。由此实现了特别紧凑的构造方式。这种拓扑结构或布局能够由此实现，即所述从动轴共轴地包围驱动轴。
第一构造方式变型方案尤其用于汽车内的纵向装配。在此，驱动轴的处于变速器之后的传动系区段与变速器轴向相邻地并且平行地或者优选共轴地定向。作为对此的备选，所述从动轴可以与垂直于驱动轴定向的传动系区段相连。从动轴尤其可以布置在第一和第二电机之间。第二构造方式变型方案主要用于横向装配，尤其是汽车内的前部横向装配。
在本发明的范围内，关于各单个元件的连接可以考虑两种变型方案。在第一种连接变型方案中，所述第一行星齿轮变速器的行星架与第二行星齿轮变速器的行星架固定相连。这种连接变型方案对于上述两种构造方式变型方案(即用于纵向装配和横向装配的变型方案)均可实现。作为对此的备选，可以在第二连接变型方案中规定，所述驱动轴借助第二离合器与第一行星齿轮变速器的行星架耦连。这种连接变型方案只在与第二构造方式变型方案(即用于横向装配的变型方案)相关联时是有意义的。上述两种连接变型方案的作用方式在以下单独阐述。在此，对第一连接变型方案的描述可以不变地转用到第二连接变型方案(在其第二离合器闭合的状态下)上。
按照第一连接变型方案的按照本发明的混合驱动装置提供两种功率分流运行模式，即超速传动范围内的固定挡位以及纯电动运行模式。
在第一功率分流运行模式下，第一离合器闭合，而第一和第二制动器断开。这种运行模式从传动比较高的启动阶段使用至接近超速传动范围，并且在混合动力行驶时提供连续的变速器调节。内燃机的扭矩通过驱动轴传导至第一行星齿轮变速器的行星架。与第一行星齿轮变速器的行星架固定相连的第二行星齿轮变速器行星架也以相同的转速旋转。然而由于将第二行星齿轮变速器的太阳轮与壳体耦连的第一制动器断开，所以第二行星齿轮组在该状态下不承接功率。驱动轴的扭矩和转速在第一行星齿轮组中传动并且通过其齿圈传导至从动轴。在此，第一电机以发电机的方式工作，其转子与第一行星齿轮变速器的太阳轮固定相连。其转速确定第一行星齿轮变速器的有效传动比。尤其为了降低驱动轴和从动轴之间的传动比(即当汽车开始行驶时)，减小第一电机的转速，其中，驱动轴的转速优选保持在内燃机的最佳效率范围内。在第一功率分流运行模式中，通过闭合的第一离合器与从动机构相连的第二电机以电动机的方式工作并且在此可以实施已知的混合功能，如助推。第一功率分流运行模式延伸至或者接近第一电机的停止点。第一电机的停止点处于接近超速传动的范围内。在相同范围内还有另一点，在该点处第二行星齿轮变速器的行星架和其齿圈的旋转这样叠加，使得第二行星齿轮变速器的太阳轮(也)停止。该点尤其在驱动轴和从动轴彼此的转速处于由第二行星齿轮变速器的标准传动比预设的比例关系时实现。该点是否能够在第一行星齿轮变速器的太阳轮的停止点之前、之后或者与其同时到达，取决于两个行星齿轮变速器的特殊参数。本领域技术人员可以根据具体使用情况进行设计。
在第二行星齿轮变速器的太阳轮的停止点处，元件(如第一制动器的制动摩擦片)之间不存在相对运动。因此，第一制动器可以在该状态下无摩擦损耗地闭合。由此实现的在第一制动器和第一离合器闭合时调节形成的运行模式相当于接近超速传动范围内的固定挡位。在该运行模式下，第二行星齿轮变速器由于其保持固定的太阳轮而用作传动内燃机扭矩并且将其传导至从动机构的单纯传动级。在此，通过第一离合器同样与从动机构相连的第二电机能够以并联混合驱动方式提供扭矩。第一电机在此一如既往地以发电机方式工作。在此，发电的制动扭矩的强度可以根据行驶情况而变化。由此尤其可以将第一制动器的负载控制为完全无负载或者满载。
第一离合器的断开导致过渡为第二功率分流运行模式。在第二功率分流运行模式中，第二电机以纯发电的方式工作。第二行星齿轮变速器由于其保持固定的太阳轮而用作单纯传动级。通过第二行星齿轮变速器的行星架施加的内燃机扭矩驱动第二电机的转子，而不将扭矩进一步传导至从动机构(由于第一离合器断开)。内燃机的扭矩通过第一行星齿轮变速器传导至从动机构，其中，第一电机以电动机方式工作并且在第一行星齿轮变速器的太阳轮上支撑扭矩。
最后还设有纯电动的行驶运行模式，其中，第一离合器断开，而第一和第二制动器闭合。这以驱动轴或内燃机的停止为前提条件，而第一电机构成该状态下的唯一扭矩源。第二电机在该状态下未被使用。尤其可以保持不为第二电机通电，因为由于将反作用在驱动轴上的扭矩支撑在壳体上的第二制动器闭合，第二电机本身不需要其支撑。因此，在状态下的第二电机内不会产生电损耗，这在整体上提高了驱动装置的效率。
至此，第一连接变型方案的工作方式与第二连接变型方案在第二离合器闭合时的工作方式相同。第二连接变型方案的特殊作用在于最后描述的纯电动行驶运行模式。通过断开第二离合器，在电动行驶运行中不会强制驱动轴或内燃机停止。驱动轴在此完全与在第一连接变型方案中第二制动器所连接的轴脱耦。第一电机一如既往地在电动行驶运行中将全部扭矩用于使机动车运动。然而可以与此无关地使用内燃机，以便通过第二行星齿轮变速器(由于其保持固定的太阳轮而用作纯传动比级)以发电机方式运行第二电机。在此是指“增程器”功能，其基本上相当于严格的串联混合运行。
在本发明的一种可使用在所有前述变型方案上的扩展设计中规定，驱动轴借助第三离合器与第一电机的转子耦连。通过在第二制动器断开时连接第三离合器，第一行星齿轮变速器(其太阳轮和行星架以相同的转速运行)作为一个整体旋转，因此实现了驱动轴与从动轴之间的传动比正好为1的直接过渡。在此，需要断开所述两个作用在第二行星齿轮变速器上的切换或通断元件中的至少一个，即第一离合器和/或第一制动器。
需要指出的是，在本说明书的范围内，电动机/发电机单元主要指的是电机。然而本发明并不局限于此。
“电动机/发电机单元”也可以一般地理解为既可以电动机方式也可以发电机方式运行的能量转换器。除了电机，也可以使用液压式/气动式泵/马达。
本发明的其它特征和优点由以下的特殊说明和附图得出。

优选实施形式的具体描述
图1至图12示出了按照本发明的混合驱动装置10的不同实施形式。相同的附图标记在附图中表示相同或者类似的元件。
以下首先整体讨论图1至图12一致的部分。接着参照各附图单独讨论各实施形式的特殊之处。
所有附图示意性地示出按照本发明的混合驱动装置的拓扑结构或布局。单独元件的特殊的结构设计实现形式不是本发明的主题。因此，在附图中没有示出结构设计上的细节，如尤其是壳体(所述装置的元件至少区段性地处于该壳体内)。
所有实施形式具有驱动轴12以及从动轴14。驱动轴12在装入状态下与尤其是内燃机的主驱动机组相连。从动轴14在装入状态下与汽车的从动机构相连，所述从动机构通常包括差速器和被驱动轴。在驱动轴12与从动轴14之间布置有按照本发明地相互连接的部件，它们根据具体的运行方式确定驱动轴12与从动轴14之间的转速传动比。尤其设有第一电机20，其带有相对壳体固定的定子22和位于内部的转子24。此外设有第二电机30，其带有相对壳体固定的定子32和位于内部的转子34。两个电机20、30可以彼此独立地运行并且通过未示出的功率电子器件在相互间以及与电存储器(尤其是电池)相连。此外，混合驱动装置具有第一行星齿轮变速器40，其带有太阳轮42、齿圈44和行星架46，既与太阳轮42也与齿圈44啮合的一组行星齿轮48可旋转地支承在行星架46上。此外设有第二行星齿轮组50。所述第二行星齿轮组同样包括太阳轮52、齿圈54和行星架56，既与太阳轮52也与齿圈54啮合的一组行星齿轮58可旋转地支承在行星架56上。此外，每个所示的实施形式包括至少三个切换元件或通断元件，即第一制动器60、第二制动器70和第一离合器80。在本发明的上下文关系中，制动器表示能够将可旋转的轴固定在壳体上的可切换元件。在本发明的上下文关系中，离合器一般表示将两个可旋转的轴与切换状态有关地暂时传递扭矩地相互连接的可切换元件。
在所有示出的实施形式中，驱动轴12与第二行星齿轮变速器50的行星架56固定相连并且至少与第一行星齿轮变速器的行星架46耦连，也就是固定相连或者通过离合器相连。在所有实施形式中，从动轴14与第一行星齿轮变速器40的齿圈44固定相连。此外，在所有实施形式中，第一电机20的转子24与第一行星齿轮变速器40的太阳轮42固定相连。在所有实施形式中，第二电机30的转子34与第二行星齿轮变速器50的齿圈54固定相连。此外，在所有实施形式中，第二行星齿轮变速器50的太阳轮52通过第一制动器60与壳体耦连。在所有实施形式中，第一行星齿轮变速器40的行星架46通过第二制动器70与壳体耦连。最后，在所有实施形式中，从动轴14通过第一离合器80与第二行星齿轮变速器50的齿圈54耦连或者与第二电机30的固定相连的转子34耦连。
按照图1的实施形式实现了四种运行模式，即第一功率分流运行模式(其从内燃机以较高扭矩的启动到达超速传动范围)、第一固定挡(其在超速传动范围内接在第一功率分流运行模式之后)、第二功率分流运行模式(其在超速传动范围内接在第一固定挡之后)以及纯电动运行模式。
在第一功率分流运行模式中，第一离合器80闭合，而第一和第二制动器60、70断开。由于第一制动器60断开，第二行星齿轮变速器50的太阳轮52自由运行，因此第二行星齿轮变速器50不能承接功率。因此，内燃机的扭矩只通过驱动轴12引入第一行星齿轮变速器40内(尤其通过其行星架56)。与从动轴14相连的第一行星齿轮变速器40的齿圈44用作输出轴。在此在第一电机20内产生的电能通过功率电子器件输入第二电机30。第二电机以电动机方式工作并且可以通过闭合的第一离合器80(通过其将转子与从动轴相连)将附加的扭矩输出给从动轴14。第一功率分流运行模式跨越了从启动至接近超速传动范围的转速和扭矩范围。在此，第一电机20的转子24的转速连续地减小。同时，驱动轴和从动轴12、14的转速接近其通过第二行星齿轮变速器50的标准传动比预设的平衡，在达到平衡时，第二行星齿轮变速器50的太阳轮52停止。
第一功率分流运行模式的行驶范围结束于此并且同时具有第一固定挡。在第二行星齿轮变速器50的太阳轮52停止时，第一制动器60的可相对彼此运动的部件也相对静止。在该状态下，第一制动器60可以无摩擦损耗地闭合。由于第二行星齿轮变速器50的太阳轮52现在保持固定，第二行星齿轮变速器用作通过驱动轴12和从动轴14之间的转速比例确定的纯传动比级。通过第二电机30，可以按照并联混合驱动方式将附加的扭矩输出给从动轴14。通过驱动轴12和从动轴14的确定转速，也确定了第一行星齿轮变速器40的行星架46和齿圈44的转速，由此也预设了其太阳轮42和进而第一电机20的转子24的转速。第一电机20一如既往地按照发电机方式工作，其中，由其承接的扭矩相应地减轻了第一制动器60的一部分负荷。
为了过渡到第二功率分流运行模式，断开第一离合器80。在该模式下，第二电机30和第二行星齿轮变速器50完全与从动轴14脱耦。第二行星齿轮变速器50由于其保持固定的太阳轮52而用作纯传动比级，第二电机30通过该纯传动比级与其余变速器无关地被驱动作为发电机。所产生的电功率通过功率电子器件传输至第一电机20。所述第一电机现在以电动机方式工作并且通过其扭矩经由太阳轮42支撑施加在第一行星齿轮变速器40的行星架上的内燃机扭矩。内燃机扭矩(同时)通过行星架46传导至第一行星齿轮变速器40。处于平衡的扭矩通过第一行星齿轮变速器40的齿圈44输出给从动轴14。
最后，在纯电动运行模式中，第一和第二制动器60、70闭合，而第一离合器80断开。在纯电动运行模式中内燃机和驱动轴12停止。反作用于驱动轴12的扭矩由第二制动器70支撑，驱动轴12借助第二制动器通过第一行星齿轮变速器40的行星架46固定在壳体上。第二行星齿轮变速器50由于其固定的太阳轮52和其固定的行星架56而是停止的；因此，第二电机30在该状态下无作用。需要注意的是，可以保持不为第二电机通电，因为尤其由于第二制动器70闭合，第二电机不需要承担反作用于驱动轴12上的扭矩的支撑功能。第一电机20在该运行模式中用作唯一的驱动机组，所述第一电机以电动机方式工作并且将其扭矩通过(由于行星架46保持固定)用作纯传动比级的第一行星齿轮变速器40传导至从动轴14。
图2示出基本上与图1的实施形式相应的一种变型方案，其中只有第一电机20和第一行星齿轮变速器40与第二电机30和第二行星齿轮变速器50对调。上述对于运行模式的阐述可以不变地适用。
在图1和图2的实施形式中，从动轴14基本上包围驱动轴12并且尤其布置在两个电机20、30之间，所以这两个实施形式尤其适用于横向装入汽车，而图3和图4的实施形式示出了按照本发明的混合驱动装置的用于纵向装入汽车的优选变型方案。在此，驱动轴和从动轴以相同的轴向彼此定向。而在可实现的运行模式和单个元件在不同运行模式中的功能与作用方面与之前的阐述没有区别，所以在此可以不变地适用之前的阐述。图3和图4的实施形式之间的区别主要在于第二电机30和第二行星齿轮变速器50与第一行星齿轮变速器40镜像对调。
图5示出图1的实施形式的一种扩展设计。在图5的实施形式中，设有第二离合器90作为附加元件，所述第二离合器将图1实施形式中处于第一行星齿轮变速器40的行星架46与驱动轴12之间的固定连接修改为离合器，即可切换或可通断的连接。在第二离合器90的闭合状态中，图5的实施形式与图1的实施形式相同。然而，通过引入附加的离合器90扩展了电动运行模式。如上所述，在电动运行模式中，第一制动器60和第二制动器70闭合，而第一离合器80断开。附加地断开第二离合器90使得在只有第一电机20用作驱动机组的电动行驶中可以与行驶运行状态无关地借助内燃机将第二电机30作为发电机运行，并且在电动行驶运行中为电池充电或者按照串联式混合驱动原理提供能量用于运行以电动机方式工作的第一电机20。这种功能也作为“增程器”已知。
图6示出了图2的实施形式的一种类似修改方案。因此可以参考针对该图的阐述以及针对图5的实施形式的阐述。
图7至图12示出图1至图6的实施形式的具有另一个即第三离合器100的变型方案。所述第三离合器将驱动轴12与第一电机20的转子24耦连。通过闭合第三离合器100，实现了传动比为1的附加固定挡。在此，必须断开第二制动器70和/或第一离合器80。在图11和图12的实施形式中，在该运行模式下闭合第三离合器90。在该运行模式下，通过驱动轴12导入的内燃机扭矩在图7至图12的所有实施形式中均通过作为一个整体运行的第一行星齿轮变速器40传导至从动轴14。由此实现了值为1的传动比。第一电机20可以如在并联式混合驱动中那样叠加扭矩。如果从第二功率分流运行模式以传动比为1的直接挡位启动，之前以电动机方式工作的电机20可以导入附加的扭矩。另一方面，也可以从第一功率分流运行模式以传动比为1的直接挡位行驶，这在实际中也是很重要的，因为传动比1处于该运行模式的范围内。通过第一制动器60和第一离合器80能够确定第二电机的功能和作用。在第一制动器60和第一离合器80敞开时，第二电机30完全与传动链脱耦并且第一行星齿轮变速器40是无负载的。在第一制动器60和第一离合器80闭合时，第一电机30以传动比作用在驱动轴12上并且可以通过第二行星齿轮变速器50引入增强的扭矩。在第一制动器60断开而第一离合器80闭合时，第二电机30无传动比地作用在驱动轴12上并且可以引入未增强的扭矩。第二电机50是无负载的。
当然，在特殊的说明中讨论的和附图中所示的实施形式只是本发明的说明性实施例。所公开的内容为本领域技术人员提供了范围较宽的变型可能性。本领域技术人员尤其可以将按照本发明的混合驱动装置的特殊参数、尺寸和结构设计与具体应用情况适配。
