本发明的进一步的优点、特征和细节将从以下说明中体现出来，其中参见附图具体地说明了两个示例性实施方案，在附图中：
图1示出了根据具有电动机器的一个第一示例性实施方案的混合动力传动系的示意图，并且
图2示出了具有另一个电动机器的类似于图1的一个示例性实施方案。
具体实施方案
图1和图2各自展示了一个根据两个不同的示例性实施方案的混合动力传动系1；41，该混合动力传动系具有一个内燃发动机2。相同的参考符号用来表示相同的或类似的部件。在下文中，首先对在这两种不同的混合动力传动系1和41中的共同特征进行说明。然后对这两个示例性实施方案之间的差异详细地进行说明。
内燃发动机2输出了一个象征性表示的驱动扭矩4，它在一个变速器5中被转换并且通过一个输出轴6被传输到机动车辆的驱动轮上，如由8象征性地表示的。变速器5被实施为一个无级变速器，具体是一种双离合器变速器。
一个离合器装置10被连接在内燃发动机2与变速器5之间。离合器装置10被实施为具有一个第一离合器11以及一个第二离合器12的一个双离合器。内燃发动机2可以通过第一离合器11连接到变速器5的一个第一变速器输入轴13上以便在旋转意义上被固定到其上。
内燃发动机2可以通过第二离合器12连接到一个第二变速器输入轴14上以便在旋转意义上被固定到其上，而所述变速器轴14被实施为一个空心轴。变速器5还包括一个副轴15，该副轴通过连接齿轮16、17被连接到输出轴6上。
使用齿轮对21、22、23、24可以形成无级变速器5的四种不同的档位(

)，以便允许在内燃发动机2与输出轴6之间的不同的传动比。第一变速器输入轴13可以通过两个齿轮对21和23连接到副轴15上。第二变速器输入轴14可以通过两个齿轮对22和24连接到副轴15上。

在图1所展示的混合动力传动系1中，电动机器30通过行星齿轮机构33被功能性地永久性地连接到第一变速器输入轴13上以及输出轴6上。这允许内燃发动机2以一种简单的方式进行冷启动。此外，这使得可以一种简单的方式在内燃发动机2、电动机器30以及输入轴6之间形成一个可变的转速比。
在图2中展示的混合动力传动系41包括一个电动机器50，从其上面延伸一个驱动轴51，它被实施为空心轴。电动机器50的驱动轴51被连接到一个行星齿轮机构53的一个行星齿轮架52上以便在旋转意义上被固定到其上。多个行星齿轮被可转动地安装到行星齿轮架52上并且与一个环齿轮(未展示)以及一个太阳轮55相啮合。太阳轮55能够通过两个齿轮57、58并且使用一个离合器56而连接到输出轴6上。行星齿轮架52通过由构成齿轮对23的齿轮39、30而永久性地连接到第一变速器输入轴19上。
混合动力传动系41包括另一个电动机器60，从该电动机器上伸出了一个驱动轴61，所述驱动轴61延伸穿过实施为电动机器50的一个空心轴的驱动轴51并且在其上附接了行星齿轮机构53的太阳轮55以便在旋转意义上被固定到其上。该另一个电动机器60的驱动轴61能够通过离合器56以及两个齿轮57、58而连接到输出轴6上。
当通过这些齿轮57和58将离合器56关闭时，另外的电动机器60可以用来驱动机动车辆的这些驱动轮。具体地讲，这使得可进行一种快速启动，也就是说在离合器56关闭之前加快了内燃发动机2的转速。可替代地或额外地，可以提供另一个电动机器(未展示)，它被功能性地连接到内燃发动机2上以将其启动。
