Description

机动车辆动力传动系的变速器组件、动力传动系及操控动力 传动系的方法
本发明涉及一种用于机动车辆动力传动系的变速器组件，所述变速器组件具有：第一输入轴和第二输入轴；副轴；第一子变速器，所述第一子变速器具有用于设定多个挡位级的多个可切换的第一齿轮组；第二子变速器，所述第二子变速器具有用于设定多个挡位级的多个可切换的第二齿轮组。
此外，本发明涉及一种用于机动车辆的动力传动系，所述动力传动系具有：燃烧发动机；双离合器组件，所述双离合器组件具有连结至所述燃烧发动机的输入构件以及两个输出构件；以及上述类型的变速器组件，其中所述第一输入轴和所述第二输入轴分别被连结至所述输出构件中的一个输出构件。
此外，本发明涉及一种混合动力传动系以及一种用于操作混合动力传动系的方法。
上述类型的变速器组件是从文件DE 102016210713 A1已知的。在该文献中公开的变速器包含：变速器轴、第一轴、指配给该第一轴的第一活动齿轮、指配给该第一轴的另外的第一活动齿轮、第二轴、指配给该第二轴的第二活动齿轮、以及指配给该第二轴的另外的第二活动齿轮。变速器轴与第一轴和/或第二轴可操作性连接。变速器包含与第一轴和第二轴处于操作性连接的变速器输出轴。第一活动齿轮借助于第一换挡元件与另外的第一活动齿轮可防旋转地连接。在第一换挡元件闭合的状态下，可选择性地实现用于前进行驶运行的第一前进挡位或用于前进行驶运行的第六前进挡位。此外，变速器可被整合到混合动力传动系中。
上述变速器通常必须被指配给所谓的双离合器变速器。近几年来，双离合器变速器形成自动变换变速器的替代方案。双离合器变速器具有双离合器组件，该双离合器组件是在输入侧与驱动机器(例如燃烧发动机)可连接的。离合器组件的第一离合器的输出构件与第一子变速器的第一输入轴连接，该第一子变速器典型地被指配给偶数前进挡位级或奇数前进挡位级。双离合器组件的第二摩擦离合器的输出构件与第二子变速器的第二输入轴连接，该第二子变速器典型地被给其他的前进挡位级。
一般来说可以使被指配给子变速器的挡位级自动化地接合和脱离接合。在正常的行驶运行中，双离合器组件的摩擦离合器中的一个摩擦离合器是闭合的。于是在其他未激活的子变速器中，可以预先切换下一挡位级。于是，通过同时致动这两个摩擦离合器可以大体上在没有发生牵引力中断的情况下执行挡位变换。
机动车辆变速器一般来说被构造成用于在前部横向安装在其中尤其关注较短轴向结构长度的机动车辆中。替代于此，变速器被构造成用于纵向安装在其中尤其关注径向紧凑结构方式的机动车辆中。
在前部的横向变速器中，输入轴组件通常被指配有轴线平行地布置的两个副轴，使得可以实现从输入轴组件经由副轴或经由另一个副轴的功率流。在此，副轴还被设计为输出轴，并且一般来说这两个副轴与差速器处于接合，以将驱动功率分配至被驱动的车轮。这种变速器例如已从以上提到的文献DE 102016210713 A1已知。
机动车辆动力传动系领域的进一步的趋势是所谓的混合动力化。通常这意味着，呈燃烧发动机形式的驱动发动机被指配有电动机器作为另外的驱动机器。在此，在多种不同构思之间存在区别，这些构思各自提出了电动机器与变速器的不同连接方式。在双离合器变速器中，可以看到典型的变体(也参见以上提到的DE 102016210713 A1)在于：将电动机器与双离合器组件的输入构件布置成同中心的。在这种情况下，电动机器不仅可以用于支持燃烧发动机，而且可以设定纯电动机式的行驶运行，双离合器组件的输入构件在此一般来说藉由分离离合器或燃烧发动机脱离联接装置与燃烧发动机连接。
变速器的混合动力化在开篇提及的对径向和/或轴向结构空间的要求方面提出了较高的要求。
在此背景下，本发明的目的在于，给出一种经改进的变速器组件、一种用于机动车辆的经改进的动力传动系、一种经改进的混合动力传动系、以及一种用于操作这种混合动力传动系的经改进的方法。
上述目的一方面通过一种用于机动车辆动力传动系的变速器组件来实现，所述变速器组件具有：第一输入轴和第二输入轴；副轴；第一子变速器，所述第一子变速器具有用于设定多个挡位级的多个可切换的第一齿轮组；第二子变速器，所述第二子变速器具有用于设定多个挡位级的多个可切换的第二齿轮组；桥式离合器，所述桥式离合器被设计成用于将所述第一子变速器和所述第二子变速器联接，以便设定至少一个扭力挡位级。
此外，上述目的还通过一种用于机动车辆的动力传动系来实现，所述动力传动系具有：燃烧发动机；双离合器组件，所述双离合器组件具有连结至所述燃烧发动机的输入构件以及两个输出构件；以及根据本发明类型的变速器组件，其中所述第一输入轴和所述第二输入轴分别被连结至所述输出构件中的一个输出构件。
此外，上述目的还通过一种混合动力传动系来实现，所述混合动力传动系具有：根据权利要求1至7之一所述的变速器组件；以及第一电动机器，所述第一电动机器被连结至双离合器组件的输入构件，所述双离合器组件的输出构件与所述第一输入轴或所述第二输入轴相连接；和/或第二电动机器，所述第二电动机器被连结至所述第一输入轴或所述第二输入轴。
最后，上述目的通过一种用于操作根据本发明类型的混合动力传动系的方法来实现，所述方法具有如下步骤：借助于所述第一电动机器并且/或者借助于所述第二电动机器使所述非同步换挡离合器的换挡过程同步。
在根据本发明的变速器组件中，第一输入轴与第二输入轴优选彼此同中心地布置，其中第一输入轴优选被设计为空心轴并且其中第二输入轴优选被布置为内轴。变速器组件优选地具有恰好一个副轴。优选地，副轴同时是变速器组件的输出轴。优选地，为此目的副轴与从动齿轮连接，该从动齿轮被设计成用于驱动功率分配组件(例如差速器)。
可切换的齿轮组在此被理解为以下齿轮组，这些齿轮组具有啮合式地处于彼此接合的活动齿轮和固定齿轮并且借助于所指配的换挡离合器可被切换。在被切换的齿轮组中，这个齿轮组的活动齿轮与所指配的轴防旋转地连接。齿轮组优选地是正齿轮组，这些正齿轮组优选分别将这两个输入轴中的一个输入轴和副轴相互连接。
每个齿轮组优选地被指配有常规的前进挡位级，即固定的传动比。常规的前进挡位级被理解为如下前进挡位级，即，该前进挡位级通过使单独的换挡离合器或单独的换挡元件闭合可以切换到功率流中。
而借助于桥式离合器可以设定至少一个扭力挡位级。该至少一个扭力挡位级优选是前进扭力挡位级。在设定扭力挡位级的情况下，功率从第一子变速器流动至第二子变速器或反之亦然。为了设定扭力挡位级，通常必须使桥式离合器以及另外的换挡离合器或另外的换挡元件闭合。换言之，与常规的前进挡位级(在该常规的前进挡位级，仅须使一个换挡元件闭合)不同，为了设定扭力挡位级一般必须使至少两个换挡元件闭合。
第一子变速器在一个优选的实施方式中被指配给偶数前进挡位级，而在一个替代性的实施方式中被指配给奇数挡位级。以相对应的方式，第二子变速器在一个优选的变体中被指配给奇数前进挡位级，而在一个替代性的实施方式中被指配给偶数挡位级。
变速器组件优选与双离合器组件相连接，其中第一输入轴优选与双离合器组件的一个离合器相连接，并且其中另外的输入轴优选与双离合器组件的另一个离合器相连接。
连结或连接在此被理解为设有在转动意义上固定的联接(即，操作性连接)，在该联接过程中相互连接或相互连结的元件以成比例的转速旋转。
在混合动力传动系中，电动机器一般来说具有转子和定子。定子一般是与壳体固定的。在一个实施方式中，转子防旋转地与变速器组件的轴(例如与双离合器组件的输入构件的轴区段)相连接。替代于此，转子可以与马达小齿轮(其是机器联接齿轮组的一部分)相连接，以便尤其借助于正齿轮组将功率传递到轴上。
在根据本发明的方法中，变速器组件可以包含同步换挡元件或同步换挡离合器(其被设计为摩擦离合器)。这种换挡元件典型地由锁定-同步件来实现。然而在混合动力传动系中，一些换挡元件也可以通过非同步换挡元件或爪式离合器来实现，这些非同步换挡元件或爪式离合器一般只有在要彼此连接的构件已经进行了同步时才进行切换，其中尤其通过第一电动机器和/或第二电动机器来进行该同步。
借助根据本发明的变速器组件可以实现的是，仅借助于与功率分配装置(例如差速器)的单独的连结来实现(例如从文献DE 102016210713 A1已知的)功能。通过这种方式方法可以提供结构空间，更确切地说尤其用于整合至少一个电动机器以设定混合动力传动系、尤其用于以轴线平行的方式方法连结电动机器，其方式为使得电动机器藉由呈正齿轮组形式的机器联接齿轮组与变速器组件相连接。
在一个优选的变体中，从变速器组件的输入端开始的元件的顺序如下：用于前进挡位级2的齿轮组、用于前进挡位级2和4的换挡离合器组、用于前进挡位级4的齿轮组、用于前进挡位级3的齿轮组、用于前进挡位级3和5的换挡离合器组、以及用于前进挡位级5的齿轮组。
在一个替代性的实施方式中，变速器组件中的元件的轴向顺序如下：用于前进挡位级5的齿轮组、用于前进挡位级5和3的换挡离合器组、用于前进挡位级3的齿轮组、用于前进挡位级4的齿轮组、用于前进挡位级4和2的换挡离合器组、以及用于前进挡位级2的齿轮组。
在优选的设计方案中，所有的换挡离合器均被布置在副轴上，然而这些换挡离合器也可以至少部分地布置在这些输入轴中的一个输入轴上。
所述桥式离合器也优选被布置在所述副轴上。在一个替代性的设计方案中，桥式离合器被布置在另外的副轴上，该另外的副轴藉由联接齿轮组与第一子变速器或第二子变速器相连接。
在混合动力传动系中，电动机器可以在双离合器组件前方连结至动力传动系。在这种情况下，电动机器可以被设定成用于增压运行、用于启动燃烧发动机、以及用于一系列其他目的。在提供燃烧发动机脱离联接装置的情况下，还可以在所有行驶级实现电动机式的行驶运行。
替代于此或除此之外，将电动机器连结至这些子变速器中的一个子变速器的输入端。在这种情况下可以藉由那个子变速器来实现电力的行驶运行。然而，电动机器也可以用来进行增压、以及在发电机式的运行期间用来给电池充电、以及用来启动燃烧发动机等。
该目的完全被实现。
根据一个优选的实施方式，所述桥式离合器被布置在所述副轴上。
在这个实施方式中可以实现径向紧凑的结构方式。
在此优选的是，所述桥式离合器在轴向上被布置在所述第一子变速器与所述第二子变速器之间。
由此，可以在结构上简单地实现子变速器的联接。
根据另一个实施方式，所述桥式离合器被布置在另外的副轴上，所述另外的副轴藉由第一联接齿轮组与所述第一子变速器联接并且所述另外的副轴藉由第二联接齿轮组与所述第二子变速器联接。
联接齿轮组优选包含不可切换的恒定齿轮组以及可切换的齿轮组，该可切换的齿轮组是可以借助于桥式离合器来切换的。
通过将桥式离合器布置在另外的副轴上可以实现轴向紧凑的结构方式。
在此特别优选的是，所述桥式离合器被布置在所述第一联接齿轮组与所述第二联接齿轮组之间的轴向空隙的轴向外部。这些联接齿轮组中的至少一个联接齿轮组包含用于设定常规的前进挡位级的齿轮组的固定齿轮。
总体上还优选的是，所述第一子变速器和/或所述第二子变速器分别具有恰好两个齿轮组，所述恰好两个齿轮组被指配给常规的前进挡位级。
特别优选的是，第一子变速器具有用于前进挡位级2和4的齿轮组、或者第一子变速器具有用于前进挡位级3和5的齿轮组。此外优选的是，第二子变速器在上述第一变体中具有用于前进挡位级3和5的两个齿轮组，并且该第二子变速器在第二变体中具有用于前进挡位级2和4的两个齿轮组。
根据另一个总体上优选的实施方式，所述第一子变速器和/或所述第二子变速器的齿轮组的传动比相互协调成使得：与所述第一子变速器和所述第二子变速器的、被指配给常规的前进挡位级的所有齿轮组相比，第一前进扭力挡位级具有较短的传动比；并且/或者与所述第一子变速器和所述第二子变速器的、被指配给常规的前进挡位级的所有齿轮组相比，第二前进扭力挡位级具有较长的传动比。
在这个实施方式中，利用在设定扭力挡位级时一般涉及至少两个齿轮组来使得可设定非常长的传动比或非常短的传动比。第一前进扭力挡位级优选为变速器组件的起步挡位级。第二前进扭力挡位级优选是具有最长传动比或最高传动比的前进挡位级，即，例如是在具有四个齿轮组的上述情况下与前进挡位级6相对应的传动比。
在根据本发明的混合动力传动系中优选的是，所述双离合器组件的输入构件与燃烧发动机可藉以连结至所述输入构件的燃烧发动机脱离联接装置相连接。
由此，针对电动机器被连结至双离合器组件的输入构件的这种情况，可以设定电力的行驶运行而不必使燃烧发动机联动。
此外有利的是，所述第一电动机器藉由第一机器联接齿轮组被连结至所述输入构件；并且/或中所述第二电动机器藉由第二机器联接齿轮组被连结至所述第一输入轴或所述第二输入轴。
通过这种方式方法可以以轴线平行的方式对(多个)电动机器进行整合，以便可以通过这种方式尤其在轴向方向上实现紧凑的结构方式。
根据另一个总体上优选的实施方式，所述第一电动机器被连结至所述双离合器组件的输入构件，其中所述第二电动机器被连结至所述第一输入轴或所述第二输入轴，其中被指配给所述第二电动机器的那个子变速器的齿轮组是借助于非同步换挡离合器或爪式离合器可切换的。
根据另一个优选的实施方式，所述第一电动机器被连结至所述双离合器组件的输入构件，其中所述第二电动机器被连结至所述第一输入轴或所述第二输入轴，并且其中所述双离合器组件具有第一非同步换挡离合器或爪式离合器和/或第二非同步换挡离合器或爪式离合器。
根据另一个总体上优选的实施方式，所述燃烧发动机脱离联接装置具有非同步换挡离合器或爪式离合器。
不言而喻，以上提到的这些特征以及仍将在以下说明的特征不仅能够以分别给出的组合方式使用，而且还能够以其他组合方式或者单独使用，而不脱离本发明的范围。

在图1中，展示了用于机动车辆、尤其用于乘用机动车辆的本发明动力传动系的实施方式并且其总体上用10标明。动力传动系10具有燃烧发动机12，该燃烧发动机与双离合器变速器14相连接，该双离合器变速器进而在输出侧与可以借以将驱动功率分配到被驱动的车轮18L、18R上的差速器16相连接。
双离合器变速器14具有双离合器组件20，该双离合器组件包含两个离合器K1、K2。离合器K1、K2优选被设计为摩擦离合器，除非另有提及，例如被设计为湿式运行的片式离合器。
双离合器变速器14具有第一输入轴22和第二输入轴24。第一输入轴22被设计为空心轴并且与离合器K2的输出构件相连接。第二输入轴24与第一输入轴22同中心地布置并且被设计为内轴。第二输入轴24与离合器K1的输出构件相连接。
第一输入轴22被指配给第一子变速器26，该第一子变速器包含常规的前进挡位级(在此为常规的前进挡位级2和4)。第二输入轴24被指配给第二子变速器28，该第二子变速器被指配给常规的奇数前进挡位级(在此为常规的前进挡位级3和5)。
这两个子变速器26、28在轴向上彼此偏移地布置。
第一子变速器26具有用于常规的前进挡位级2的齿轮组30以及用于常规的前进挡位级4的齿轮组32。第二子变速器28具有用于常规的前进挡位级3的齿轮组34以及用于常规的前进挡位级5的齿轮组36。
齿轮组30、32、34、36分别包含固定齿轮和活动齿轮并且分别将输入轴22、24中的一个输入轴与副轴40连接。
第一子变速器26具有第一换挡离合器组42，该第一换挡离合器组具有用于切换常规的前进挡位级2和4的换挡元件S5、S4。第二子变速器28具有第二换挡离合器组44，该第二换挡离合器组具有用于切换常规的前进挡位级3和5的换挡元件S2和S1。
换挡离合器组42、44优选被布置在副轴40上。齿轮组30、32、34、36的固定齿轮以对应的方式优选与所指配的输入轴22或24相连接，并且齿轮组30、32、34、36的活动齿轮可旋转地支承在副轴40上并且是借助于相应的换挡元件与副轴40可连接的。
副轴40与借以驱动差速器16的从动齿轮46相连接。
通过对换挡元件S1、S2、S4、S5中的一个换挡元件进行切换可以相应地切换常规的前进挡位级。
在轴向上在这两个子变速器26、28之间布置有桥式离合器组件48，该桥式离合器具有换挡元件S3，该换挡元件被设计成用于将第一子变速器26和第二子变速器28相互连接。在设定常规的前进挡位级的情况下，桥式离合器组件48的换挡元件S3是常断式的。
如果使桥式离合器组件48的换挡元件S3闭合、并且如果同时使换挡元件S1、S2、S4、S5闭合，则可以设定扭力挡位级，在该扭力挡位级，功率从离合器K1、K2经由所指配的子变速器、随后经由桥式离合器组件48被传递至其他子变速器并且从那里被传递至副轴40。在此，这种挡位级也被称为扭力挡位级，即，在这种挡位级，桥式离合器组件48的换挡元件S3是闭合的并且这些另外的换挡元件S1、S2、S4、S5中的一个换挡元件是闭合的。
第一子变速器26的齿轮组30、32的传动比和第二子变速器28的齿轮组34、36的传动比相互协调成使得：与第一子变速器和第二子变速器26、28的、被指配给常规的前进挡位级的所有齿轮组相比，第一前进扭力挡位级具有较短的传动比。此外，与第一子变速器和第二子变速器的、被指配给常规的前进挡位级的所有齿轮组相比，第二前进扭力挡位级具有较长的传动比。
在此由这两个子变速器26、28以及从动小齿轮46构成的变速器组件优选不具有后退挡位级。因此，由子变速器26、28构成的变速器组件优选被设置成用于混合动力化，其中通过其旋转方向可简单逆转的电动机器来设定后退挡位级(与燃烧发动机不同)。
通常还可以设想的是，向第一子变速器或第二子变速器28中整合用于后退挡位级的齿轮组，然而于是为此一般需要另外的换挡元件。在此有利的是，换挡元件S1至S5是仅借助于三个致动器可被致动的。
变速器组件具有简单的结构和紧凑的结构方式。通过巧妙地布置齿轮组获得了较小的构件负载。尤其，具有最短传动比的齿轮组(用于前进挡位级2的齿轮组)被布置成与变速器组件的轴向端部邻近，即，该齿轮组被布置在对轴22、24、40进行支承的位置。
通过仅将最低前进挡位级和最高前进挡位级实现为扭力挡位级，还获得了较小的变速器损耗。获得了较好的啮合效率。也可以很好地实现传动比系列。
下面将描述动力传动系的另外的实施方式，这些实施方式在结构和工作方式方面总体上对应于图1的动力传动系10。相同的元件因此由相同的附图标记表示。下面大体上阐述不同之处。
图2示出经修改的动力传动系10'，在该动力传动系中第一子变速器26'具有用于前进挡位级3和5的齿轮组34'、36'、以及换挡离合器组44'。第二子变速器28'以对应的方式具有用于常规的前进挡位级2和4的齿轮组30'、32'、以及换挡离合器组48'。桥式离合器组件48'是通过相当的布置实现的，在该布置中，换挡元件S3的摩擦体被布置在换挡套筒的朝向第二子变速器28'的一侧。
在动力传动系10、10'中，换挡元件分别被设计为尤其呈所谓的锁定-同步件形式的同步式换挡元件。
图3示出前进挡位级V1至V6的换挡表。
例如通过以下方式来设定前进挡位级V1，即：使双离合器组件20的离合器K1、以及桥式离合器组件48的换挡元件S3、和用于常规的前进挡位级2的齿轮组30的换挡元件S5闭合。
使换挡元件S5保持闭合，以使前进挡位级V2接合。使换挡元件S3以及离合器K1断开并且使离合器K2闭合。
对应地，在前进挡位级V3，使离合器K1和换挡元件S2闭合。针对前进挡位级V4，离合器K2和换挡元件S4是闭合的。针对前进挡位级V5，离合器K1和换挡元件S1是闭合的。
针对前进挡位级V6，离合器K2、换挡元件S2和桥式离合器组件48的换挡元件S3是闭合的。
图3的换挡表适用于图1和图2的这两个动力传动系10、10'。
下面将阐述动力传动系的另外的实施方式，这些另外的实施方式在结构和工作方式方面与上述动力传动系相对应并且以与图3所示的相同的换挡表为基础。下面大体上阐述不同之处。
图4示出动力传动系10'，在该动力传动系中，桥式离合器组件48”被布置在另外的副轴52上。另外的副轴52与输入轴和副轴平行地布置并且藉由第一联接齿轮组54与第一子变速器26相连接。第一联接齿轮组54具有可旋转地支承在另外的副轴52上的活动齿轮，该活动齿轮与用于前进挡位级4的齿轮组的固定齿轮处于接合或相啮合。此外，另外的副轴52藉由第二联接齿轮组56与第二子变速器28相连接。更确切地说，第二联接齿轮组56具有这样的固定齿轮，该固定齿轮与另外的副轴52防旋转地相连接并且该固定齿轮与用于常规的前进挡位级3的齿轮组的固定齿轮处于接合。
在轴向上看，桥式离合器组件48”的换挡元件S3”被布置在第一联接齿轮组54与第二联接齿轮组56之间的轴向空隙的外部。由此可以实现轴向紧凑的结构方式。
在图5中示出了动力传动系10”'的另一个实施方式，该动力传动系在结构和工作方式方面通常与图4的动力传动系10”相对应。在图4的动力传动系10”中换挡元件S3”被设置成与第一子变速器26轴向重合，而桥式离合器组件48”'的换挡元件S3”'被布置在联接齿轮组54、56的轴向相反侧，即，该被布置成与第二子变速器28'轴向重合。此外，在动力传动系10”'中联接齿轮组54被设计为恒定齿轮组，并且联接齿轮组56被设计为(尤其借助于换挡元件S3”')可切换的齿轮组。
图6示出动力传动系10A的另一个实施方式，该动力传动系在结构和工作方式方面通常与图1的动力传动系10相对应。动力传动系10A被设计为混合动力传动系并且具有与输入轴组件共轴地布置的第一电动机器60。电动机器60的转子与双离合器组件20的输入构件相连接。此外，双离合器组件20的输入构件藉由燃烧发动机脱离联接装置62(被设计为分离离合器K0)与燃烧发动机12可连接。
基于燃烧发动机脱离联接装置62，可以设定纯电力的行驶运行，而不一定要使燃烧发动机联动。在纯电力的行驶运行期间使燃烧发动机脱离联接装置62断开。在其他运行状态下(例如在增压运行期间或者为了启动燃烧发动机)，使燃烧发动机脱离联接装置62闭合。
即使在纯燃烧发动机式的运行期间，脱离联接装置62也自然是闭合的，以便能够将功率从燃烧发动机传递至双离合器组件20。
图7示出动力传动系10A'的另一个实施方式，该动力传动系具有第一电动机器60'，该第一电动机器是轴线平行(即，与输入轴组件平行偏移)地定向的。第一电动机器60'藉由第一机器联接齿轮组66与双离合器组件20的输入构件相连接。这个设计方案也可以有助于实现紧凑的结构方式。此外，可以使用以非常高的转速运行的电动机器，这是因为通过机器联接齿轮组66可以对燃烧发动机的转速进行调整。由此，第一电动机器60'可以设计得非常紧凑。
在图8中示出10A”，其为动力传动系的另一个实施方式，在该动力传动系中没有设置第一电动机器、然而设有第二电动机器70，该第二电动机器藉由第二机器联接齿轮组72连结至第二输入轴。更确切地说，第二电动机器70具有转子，该转子与机器小齿轮相连接，该机器小齿轮直接地或者藉由中间齿轮与用于前进挡位级3或5的齿轮组中的一个齿轮组的固定齿轮处于接合(在此与用于前进挡位级5的齿轮组的固定齿轮处于接合)。
在图7和8的实施方式中，第一电动机器60或第二电动机器70可以被设计成与变速器组件和/或双离合器组件的至少一部分轴向重合，以便以这种方式实现轴向紧凑的结构方式。电动机器60'和/或电动机器72的轴向延伸尺寸小于子变速器26、28和双离合器组件20的轴向长度。
在图9中示出了动力传动系10A”'的另一个替代性实施方式，在该动力传动系中第二电动机器70”'藉由第二机器齿轮组72”'连结至第一子变速器26、尤其连结至第一子变速器的这些齿轮组中的一个齿轮组的固定齿轮(在此连结至用于常规的前进挡位级2的齿轮组的固定齿轮)。在此可以直接进行连结，然而优选藉由中间齿轮进行连结，这在图9中(与在图8中类似地)藉由虚线示出。
在图10中示出了动力传动系10AIV的另一个优选实施方式。在动力传动系10AIV中，大体上将图8和图9的驱动构思相互组合。在此，动力传动系10AIV具有第一电动机器60'，该第一电动机器藉由第一机器齿轮组66与双离合器组件10AIV的输入构件相连接。此外，第二电动机器70藉由第二机器齿轮组72与第二子变速器相连接，更确切地说，与用于常规的前进挡位级5的齿轮组的固定齿轮相连接。
在图11中展示了动力传动系10AV的另一个实施方式，该动力传动系在结构和工作方式方面总体上与图10的动力传动系10AIV相对应。然而，在动力传动系10AV中，子变速器26'、28的轴向布置是互换了的，尤其与在图2的动力传动系10'中一样。在此，第一子变速器26'包含常规的前进挡位级3和5，并且第二子变速器28'包含常规的前进挡位级2和4，其中第二机器齿轮组72被连结至用于前进挡位级2的齿轮组的固定齿轮。
在动力传动系10AIV和10AV中，第一电动机器60'相应地优选在轴向上与双离合器组件20V和第一子变速器26或26'对齐，并且该第一电动机器大体上从双离合器组件20IV的输入构件延伸直至桥式离合器组件。
第二电动机器70在轴向方向上被布置在这两个子变速器26、28的彼此距离最远的齿轮组之间，即，被布置成与由子变速器26、28构成的变速器组件轴向重合。
在图1和2的实施方式中以及在大多数另外的实施方式中，换挡元件S1至S5相应被实现为同步换挡元件或具有摩擦元件的换挡元件、尤其被实现为锁定-同步件。
在图8的动力传动系中，第二电动机器70被连结至第二子变速器28。因此可以实现的是，动力传动系10A”的换挡元件S1”和S2”被实现为非同步换挡元件或爪式离合器。
这在图9中对应地进行了展示，其中在此第二电动机器70”'连结至第一子变速器26，从而使得也可以将换挡元件S4和S5实现为非同步换挡元件或爪式离合器。
在图10和图11的实施方式中，与第二电动机器70相连结的第二子变速器28、28'的换挡元件S2”、S1”或S4V、S5V被设计为非同步换挡元件或爪式离合器。此外可以由大体上非同步换挡元件或爪式离合器来实现图10和图11的动力传动系的双离合器组件20IV，这是因为在必要时可以藉由第一电动机器60'来进行同步。出于相同的原因，图10和图11的实施方式中的燃烧发动机分离装置62IV还可以被设计为非同步换挡元件或爪式离合器K0。
即使在图6和图7的实施方式中也可以将燃烧发动机脱离联接装置62实施为摩擦配合的离合器或形状配合的离合器。
在所有实施方式中应理解的是：代替用于连结电动机器的齿轮组(机器齿轮组60或72)，相应地还可以使用链条或条带来连结相应的电动机器。
在仅设有相应连结至子变速器(图8和图9)的电动机器的实施方式中，可以相应地藉由指配给所指配的子变速器的挡位级来进行纯电力的行驶运行。例如，在图8的实施方式中可以藉由前进挡位级1、3和5来进行纯电力的行驶运行。在图9的实施方式中可以藉由前进挡位级2、4和6来进行纯电力的行驶运行。于是仅可以以中断牵引力的方式来实现在纯电力的行驶运行期间进行挡位变换。由于可以相应地藉由所指配的双离合器组件来使电动机器与燃烧发动机脱离联接，因此无需燃烧发动机脱离联接装置。
在图10和图11的设有两个电动机器的实施方式中，即使在纯电力的行驶运行期间也可以在必要时在获得牵引力的情况下进行挡位变换(根据电动机器彼此的尺寸比例)。
