Description

用于混合动力传动系统的结构单元
技术领域
本发明涉及一种用于机动车辆的混合动力传动系统的结构单元，具有：带有定子和转子的电机，其中，转子设计成将扭矩传递到传动系统上；具有离合器操纵单元的离合器组件，其中，该离合器组件设计成使平行于用于传递扭矩的电机设置的内燃机与传动系统断开联接；以及用于减小传动系统中振动的振动缓冲装置、尤其是离心力缓冲器。
背景技术
不仅在传统的而且在混合动力传动系统中，已知使用减小振动的系统用于振动解耦。在此，尤其地使用转速适应性缓冲器和双质量飞轮的组合以实现尽可能好的舒适性。为了占用尽可能少的结构空间，在此从现有技术中已知，将转速适应性缓冲器径向地布置在双质量飞轮之内。此外，从现有技术中已知，在混合动力驱动机构中设置分离离合器以用于使电机与驱动设备或在电机之内的缓冲器连接或分离。
然而，在混合动力驱动机构的几种结构空间规定中，不能实现将转速适应性缓冲器布置在双质量飞轮之内。此外，轴向结构空间有限，从而没有空间来轴向并排地安装双质量飞轮、转速适应性缓冲器和分离离合器。由于结构空间不足，因此在结构空间狭窄时曾省去转速适应性缓冲器。
然而这具有的缺点是，必须承受由剩余扭矩不均匀性引起的舒适性损失。
发明内容
因此，本发明的目的是，提供一种用于车辆的混合动力传动系统的结构单元，其能够实现在最为狭窄的轴向结构空间上除了双质量飞轮之外还安装转速适应性缓冲器。
所述目的通过根据权利要求1所述的结构单元以及根据权利要求17所述的混合动力传动系统装置实现。
根据本发明，提供一种用于机动车辆的混合动力传动系统的结构单元，该混合动力传动系统包括内燃机和用于传递扭矩的电机。该结构单元至少包括具有定子和转子的电机，其中，转子设计成将扭矩传递到传动系统上。此外，该结构单元还具有带有离合器操纵单元的离合器组件和用于减小在传动系统中振动的振动缓冲装置。在此，离合器组件设计成，使平行于用于传递扭矩的电机设置的内燃机与传动系统断开联接或者与传动系统相联接。
根据本发明的第一方面，本发明基于以下这样的想法，即，离合器操纵单元轴向地布置，在径向方向上基本上在振动缓冲装置之内。因为离合器操纵单元径向地布置在振动缓冲装置之内，可获得轴向的结构空间，从而结构单元整体上紧凑地构造。
在此还有利的是，振动缓冲装置不像从现有技术中已知的那样轴向地布置在电机、尤其是转子旁边，而是径向地布置在转子之内。由此，可获得更多的轴向结构空间，从而结构单元还可设计成更紧凑。
根据另一有利的实施例，在此径向地在转子之内不仅布置振动缓冲装置和离合器操纵单元，而且离合器组件的其它元件，特别是压紧板、和/或离合器盘和/或压力板和/或与离合器操纵单元共同作用的弹性复位元件也可基本上径向地布置在转子之内。这进一步减小了轴向结构空间需求。
显然，当然也可行的是，仅仅离合器组件的元件，例如压紧板、离合器盘、压力板或弹性复位元件径向地布置在转子之内，而振动缓冲器和径向地布置在振动缓冲器之内的离合器操纵单元可轴向地布置在转子旁边。因为特别是离合器装置的元件在轴向上具有很大的结构空间需求，所以在这种情况下也给出紧凑的结构单元。
根据本发明的另一方面，本发明基于以下这样的想法，即，在以上描述的结构单元中，振动缓冲装置和离合器组件的至少一个元件、特别是压紧板、和/或离合器盘和/或压力板和/或与离合器操纵单元共同作用的弹性复位元件轴向地布置，在径向方向上基本上在转子之内。由于如以上已经简要指出的那样，特别是离合器组件的元件以及当然振动缓冲装置的元件在轴向上需要最大的结构空间，所以这些元件布置在转子的径向内部区域中的布置方案是有利的并且实现了用于混合动力驱动机构的结构单元的非常紧凑的设计方案。
如另一有利的实施例示出的那样，在此离合器操纵单元也可轴向地布置，在径向方向上基本上在振动缓冲装置之内，从而实现了极其紧凑的结构单元。
根据另一有利的实施例，振动缓冲装置构造为具有可沿着偏转轨道偏转的至少一个缓冲质量的转速适应性振动缓冲器。除了通常使用的吸收扭矩不均匀性之主要部分的双质量飞轮以外，附加存在的转速适应性缓冲器可与剩余的扭矩不均匀性相反地作用，从而几乎补偿了可能存在的旋转振动振幅。由此，可实现特别好的振动解耦。由于以上描述的各个元件的可行布置方案，此外可实现极其紧凑的结构单元，该结构单元还可简单地进行装配。
根据另一有利的实施例，振动缓冲装置不可相对旋转地布置在转子上。由此，转子可用作用于转速适应性缓冲质量的破裂保护。
根据另一有利的实施例，振动缓冲装置还具有至少一个缓冲质量架，所述缓冲质量架设计为承载所述至少一个缓冲质量，从而缓冲质量摇摆地得到支承。在此，有利地，该缓冲质量架与转子不可相对旋转地连接，其中，该缓冲质量架可制成转子的一部分或独立构造的元件。
根据另一有利的实施例，振动缓冲装置具有缓冲质量架，所述缓冲质量架带有至少一个布置在缓冲质量架的一侧处的第一缓冲质量和至少一个布置在缓冲质量架的另一侧处的第二缓冲质量。当应提供非常多缓冲质量时，缓冲质量可通过分别布置在架两侧的缓冲质量提供，这是特别有利的。
根据另一有利的实施例，振动缓冲装置构造为，其还具有第一缓冲质量架和第二缓冲质量架，所述第一缓冲质量架和第二缓冲质量架设计为以包围的方式容纳所述至少一个缓冲质量。由此，可形成非常稳定的振动缓冲器。
根据另一有利的实施例，第一缓冲质量架与转子不可相对旋转地连接，而第二缓冲质量架特别是借助于固定件、优选地借助于定距栓不可相对旋转地固定在第一缓冲质量架处。由此，缓冲质量架、缓冲质量、缓冲质量架的单元可预制成结构单元并且直接固定在转子处。
在此还可为有利的是，第一缓冲质量架与转子构造为集成的。由此，减小了待装配的元件的数量，并且可进一步节省轴向结构空间和重量。
出于优化结构空间的原因，此外，两个缓冲质量架之一可构造为转子位置传感器-转子架或者容纳转子位置传感器-转子架。在此，转子位置传感器-转子架或进行容纳的缓冲质量架与转子架相连接，而另一缓冲质量架要么与转子架构造成一体要么借助于以上描述的固定件固定在转子架上或者支撑在另一缓冲质量架-转子位置传感器-转子架上。
根据另一有利的实施例，转子具有朝向径向内部延伸的转子突起部。其特别是可用作缓冲质量架或用作用于缓冲质量架的固定元件。为此，在构造转子时转子突起部可直接作为铸件形成。
在此，一般性而言，在转子架或转子突起部和缓冲质量架之间的固定例如可借助于焊接、倾斜螺纹连接、铆接、螺纹连接、压密、和/或槽-弹簧连接实现。
除了用于缓冲质量架的固定或作为缓冲质量架之外，转子突起部替代地或附加地也用作用于离合器组件的至少一个元件、特别是用于离合器组件的弹性复位元件的支撑元件。由于弹性复位元件大多为借助于离合器操纵单元对离合器组件的压力板施加力的膜片弹簧，膜片弹簧必须支撑在轴向固定的元件处，该元件用作用于膜片弹簧的旋转点。为此一方面可使用转子架，但是另一方面转子突起部也可用于此。如果使用转子突起部，则离合器整体可与转子架无关地布置在转子之内，从而产生非常紧凑的结构单元。
在权利要求、附图和说明中定义了其它优点和有利的设计方案。
附图说明
下面应根据在附图中示出的实施例详细描述本发明。在此，所示出的实施例纯粹是示例性的并且不应确定本发明的保护范围。本发明保护范围仅仅通过所附的权利要求书限定。
附图中：
图1示出了结构单元的根据本发明的第一实施例的示意图；以及
图2示出了根据本发明的结构单元的第二实施例的示意图。
以下相同或功能相同的构件设有相同的附图标记。
具体实施方式
首先应明确指出的是，图1和图2示出了结构空间最大优化的解决方案，在其中，离合器组件、振动缓冲器和离合器操纵单元径向地布置在电机之内，以实现极其紧凑的用于混合动力传动系统的结构单元。但是这也意味着，尤其是除了在此示出的实施例，本发明也包括以下这样的解决方案，即，允许振动缓冲器和/或离合器组件沿轴向布置在转子旁边的解决方案。例如可将振动缓冲器轴向地布置在转子旁边，但是其中，用于离合器的操纵单元轴向地布置在相同的结构空间上但径向地布置在振动缓冲器之内。同样可行的是，离合器组件的仅仅一个元件和振动缓冲器径向地布置在转子之内，而离合器操纵单元轴向地布置在转子旁边。
在图1和图2中示出的非常紧凑的结构单元尤其具有以下优点，其在轴向上占据非常少的结构空间并且另一方面可用作预制的装配单元。由此，尤其是可简化并加速装配过程。
图1和图2分别示出了结构单元1，所述结构单元包括带有定子4和构造为内转子的转子6的电机2。转子6具有转子架8，该转子架包括轴向区段10和径向区段12。此外，转子架8具有转子突起部14，该转子突起部构造成与转子架8集成的。在图1和图2所示的实施例中，转子突起部14此外设计成用于将扭矩传递到变速器输入轴18上。为此，转子突起部14径向内部地具有固定元件15，该固定元件与毂元件16相连接。毂元件16又与在图中仅示意性示出的变速器输入轴18不可相对旋转地连接。
为了如在混合动力传动系统中常见的那样要么内燃机(未示出)要么电机2以传递扭矩的方式与变速器输入轴18相联接，还设有分离离合器20，该分离离合器在图1和图2所示的实施例中同样径向地布置在转子6之内。
此外，图1和图2示出了分离离合器20的压紧板22构造成与转子架8的径向突起部12集成一体。分离离合器20还具有压力板24和具有摩擦衬片的离合器盘26，所述摩擦衬片设计成与压紧板22产生摩擦连接。由于离合器盘26又与内燃机的从动轴29不可相对旋转地连接，在离合器装置20闭合的状态下扭矩从内燃机传递到变速器输入轴18上。从动轴29在附图中再次仅仅示意性地示出。
如还可从图中得到的那样，膜片弹簧形式的弹性复位元件28被分配给离合器20，该复位元件一方面支撑在转子突起部14上并且另一方面支撑在用作支座的元件42上，并且将分离离合器保持在常闭的状态中。为了使分离离合器20打开并且由此实现仅仅电机2将扭矩传递到变速器输入轴18上，还设有离合器操纵单元30，该离合器操纵单元对膜片弹簧28施加力并且由此实现离合器20的打开。
如同样可从图1和图2中得到的那样，在此离合器操纵单元30径向地布置在振动缓冲器32之内。
由于分离离合器20和振动减振装置32径向地布置在转子6之内，可实现非常紧凑的结构单元。与从现有技术、例如文献DE 10 2009 039076中已知的混合动力传动系统(在其中，不仅离合器而且振动减振装置以及离合器操纵单元轴向地并排布置)相比，径向的连接实现了显著的空间节省。
如可从图1中得到那样，振动缓冲装置32可具有缓冲质量架34，该缓冲质量架带有侧向地布置在其上的质量36、38，其中，缓冲质量架34与转子架8不可相对旋转地固定在径向区段10上。同样可行的是，借助于固定元件40将缓冲质量架34固定在转子突起部14上。在此，振动缓冲器构造为转速适应性缓冲器，其具有以摇摆的方式悬挂的质量36、38。这种类型的振动缓冲器的原理从现有技术中是已知的。
优选地，在图1中示出的缓冲质量架34可借助于焊接、倾斜螺纹连接、铆接、螺纹连接、压密或槽-弹簧连接固定在转子架8上，然而也可行的是，其与转子架8构造成一体的或集成的。
作为在图1中示出的振动缓冲器的替代，如图2示出的那样，振动缓冲器也可具有两个缓冲质量架34、35，其将质量36容纳在它们之间。在此，缓冲质量架34、35再次与转子架8不可相对旋转地连接，其中，可以结合在轴向区段10和/或转子突起部14上。
应再次明确指出的是，离合器装置20、振动缓冲装置32和操纵装置30的轴向布置方式仅仅是示例性的，同样也可不同地设计。
如果如在图2中示出的那样存在两个侧向布置的缓冲质量架34、35，两个侧向的缓冲质量架34、35之一也可通过例如转子突起部14构成。
此外可行的是，虽然一个侧向的缓冲质量架34、35例如借助焊接、倾斜螺纹连接、铆接、螺纹连接、压密或槽-弹簧连接与转子架8不可相对旋转地连接，然而另一缓冲质量架35、34甚至不必具有任何与转子架8的结合部，而是例如可借助于定距栓固定在另一缓冲质量架34、35上。
此外可行的是，两个缓冲质量架34；35之一通过转子位置传感器-转子架构成或者容纳转子位置传感器-转子架。在此，转子位置传感器-转子架借助于所述连接方案与转子架8相连接。两个缓冲质量架35、34之另一个在此可又与转子架8构造成一体或者借助于以上描述的方法固定在该转子架处或者通过间隔栓支撑在另一缓冲质量架34、35上。
总地来说，根据本发明的设计方案实现了明显更紧凑的混合动力传动系统的结构，其中，最大化的解决方案得到离合器装置、离合器操纵单元和振动缓冲器径向地布置在电机之内的布置方式。因为操纵装置径向地布置在缓冲质量之内，所以在电机之内用于缓冲质量和离合器盘的最大可能半径也是可行的。此外，得到由离合器、离合器操纵装置、电机和缓冲器组成的结构单元，其是非常紧凑的减小振动的且传递扭矩的结构单元，并且此外还简化了装配过程。此外，缓冲质量架可构造成转子的一部分，这又具有的优点是，转子附加地可用作用于转速适应性缓冲器的破裂保护。
