Description

混合动力车辆的传动系
技术领域
本发明涉及一种混合动力车辆的传动系，该混合动力车辆的传动系包括内燃发动机、至少一个第一电动机、至少一个第一离合器安排以及至少一个传动安排，并带有蓄电安排以及至少一个辅助单元(例如像空调压缩机)，其中该内燃发动机通过该离合器安排和该传动安排而与一个第一驱动桥驱动连接，并且该第一电动机与一个第二驱动桥以及与该蓄电安排和/或该辅助单元驱动连接。
背景技术
例如从DE 10 2009 050 957 A1中已知此种传动系。尤其是，这个公开文件披露了一种传动系，其中内燃发动机与第一驱动桥(在此情况下是后桥)驱动连接，并且第二电动机与第二驱动桥(在此情况下是前桥)驱动连接。以此方式，能够对机动车辆传统地只通过内燃发动机来进行驱动，或通过电动机和内燃发动机两者以混合方式进行驱动，或仅通过前桥进行驱动(即完全通过电动机进行驱动)。然而，在此所示的这种安排具有的缺点是其需要非常大的安装空间、并具有非常低的效率，特别是就电动机而言。
发明内容
因此，本发明的目的是避免上述缺点并提供一种传动系，该传动系就驱动概念而言能够以最大可能的灵活性来控制、同时需要非常小的安装空间。
根据本发明，这个目的是借助于以下事实来实现的，即该第一电动机具有一个转子轴，该转子轴在第一端通过第一选择器单元与第二驱动桥驱动连接、并且在第二端通过第二选择器单元与该内燃发动机的曲轴驱动连接。这是一种能够使第一电动机与内燃发动机平行设置的简单方式，具有显著的包装优点。另外，该第一电动机被安排成紧邻第二驱动桥(例如前桥)，并且只通过第一选择器单元(例如通过前桥差速器)与前桥直接驱动连接。通过第一电动机与曲轴的驱动连接，能够驱动辅助单元(例如空调压缩机)。通过第一电动机进行内燃发动机的发动机起动也是一个简单的问题。在两种情况下，发生了第二选择器单元的关闭。当第一选择器单元打开、第二选择器单元关闭时，内燃发动机可以驱动第一电动机，该第一电动机是作为发电机而操作的，同时机动车辆是静止的，从而用以发电并对蓄电安排进行充电(静态充电)。当第一选择器单元关闭、第二选择器单元打开时，该电动机器还可以作为发电机而操作，用以通过使用机动车辆滚动的动能在前桥发电(能量回收)。
在一个特别有利的实施例中，具有一个第二电动机，其在传动安排的下游通过第三选择器单元与第一驱动桥驱动连接。由于第二电动机例如通过万向轴和差速器与第一驱动桥(例如后桥)直接地驱动连接，不再有由于插入的传动安排造成的任何损失，其结果是大大增加了第二电动机的效率。另外，通过相对简单的这种传动系的实施例可以实现纯电动全轮驱动的概念。作为替代方案，当然还能提供一个第二电动机，该第二电动机在第一离合器安排的上游与第一离合器安排的输入轴驱动连接。在这个实施例中，在第二电动机与第一离合器安排之间可以设置第二离合器安排，但不是必须的。
通过皮带传动可以有利地建立第一电动机与曲轴之间的驱动连接。
附图说明
本发明在以下通过附图予以更详细地解释，其中这个单一的图示出了根据本发明的传动系的示意图。
具体实施方案
这个单一的图示出了用于混合动力车辆(未进一步示出)的传动系2的示意图。传动系2具有内燃发动机4，该内燃发动机通过离合器安排6(在这种情况下是双离合器)、变速器8和万向轴10与第一驱动桥14(在这种情况下是后驱动桥)的第一差速器12连接。对于传动安排8的具体实施例在此没有给出进一步的细节。第一电动机16与内燃发动机4平行设置，并且通过第一选择器单元18和差速器20与第二驱动桥22(在这种情况下是前轮轴)驱动连接。另外，电动机16通过第二选择器单元24和皮带传动26而与内燃发动机4的曲轴28连接。在其转子轴的第一端，第一电动机16通过第一选择器单元18与前轮轴22驱动连接。用于使皮带传动26与内燃发动机4的曲轴28联接的第二选择器单元24与该转子轴的第二端接合。
以下将对根据本发明的传动系2的各种不同的驱动概念进行解释。除了传统的通过内燃发动机4驱动后桥14以外，当第一选择器单元18关闭、第二选择器单元24打开时，机动车辆还可以通过第一电动机16完全地由电动机驱动。当还选择了内燃发动机4时，机动车辆也是同样地以全轮驱动的模式进行操作。当第一选择器单元18打开而第二选择器单元24关闭、并且内燃发动机4以怠速模式操作时，第一电动机16可以作为发电机进行操作，并且可以对蓄电安排(未示出)进行充电(静态充电)。当第一选择器单元18关闭、第二选择器单元24打开时，第一电动机16可以同样地以能量回收模式进行操作。当第一选择器单元18打开、第二选择器单元24关闭时，第一电动机16可以通过皮带传动26另外驱动曲轴28，并且因而在适用情况下驱动辅助单元(例如空调压缩机)。还能够以此方式使用第一电动机16作为发动机的起动机来起动内燃发动机4。
在另一个有利的实施例中，传动安排8下游的第二电动机30通过第三选择器单元32与后桥差速器12驱动连接，并且因此与后桥14驱动连接。第二电动机30和第三选择器单元32的虚线图示旨在表示以下事实，即这些设计因素不是实现本发明所必需的。第二电动机30的这种安排是通过电动机以全轮驱动的模式操作车辆的一种简单方式。传动安排8不会降低第二电动机30的效率。
作为替代方案，当然还能提供一个第二电动机30’，该第二电动机用于驱动第一离合器安排6上游的后桥14，并使其与第一离合器安排6的输入轴驱动连接。在此可以想到，省略第二电动机30’的第二离合器安排(本身已知)。
