Description

具有链传动装置和张紧系统的轴线平行的混合动力模块
技术领域
本发明涉及一种用于机动车辆例如轿车、货车或其他商用车辆的动力传动系的混合动力模块，所述混合动力模块具有可由内燃机驱动的驱动轴和可由电动机驱动的连接轴，所述驱动轴和所述连接轴能经由循环牵引装置以传递扭矩的方式彼此连接。
背景技术
从DE 10 2016 205 019 A1中已知一种具有安装优化的支承机构和安装方法的轴线平行的混合驱动装置。所述文献描述了一种混合驱动装置，所述混合驱动装置具有与发动机或变速器固定的壳体以及可从内燃机和/或电机提供扭矩的扭矩传递设备，具有用于将扭矩从电机传递至扭矩传递设备的皮带，其中，与壳体固定的多件式承载件具有第一保持部件，在驱动轴方向上观察时，承载件的外轮廓设置在内燃机与在皮带内部的扭矩传递设备之间，并且具有与第一保持部件固定连接的搭接在皮带上的第二保持部件。此外，也描述了一种安装方法，其用于使皮带与扭矩输出机构和扭矩接收机构扭矩传递地进行接触并且用于将承载件安装在与发动机或变速器固定的壳体上，其中，在将皮带安装在扭矩输出机构和扭矩接收机构上之前，安装承载件的第一保持部件，并且在所述皮带安装步骤之后，将承载件的第二保持部件紧固在第一保持部件上、轴承承载件上和/或与发动机或变速器固定的壳体上。
如果在这种混合驱动装置中将链条用作循环牵引装置，则所述链条在大多数情况下必须在内燃机的旋转轴线上的大的节圆上运行，以便确保相对于电机的传动比。因此，链条在使用中承受强烈的负荷，并且运行速度尤其应视为特别关键的。应动态传递的扭矩也同样非常高。由于所述负荷，无法避免链条的拉伸和磨损。
发明内容
因此，本发明的目的是，避免或至少减轻现有技术的缺点，并且尤其提出一种系统，在所述系统中，优选地构成为链条的循环牵引装置在运行中总是具有特定的张力，所述张力优选地是恒定的。
根据本发明，本发明的目的在这种混合动力模块中通过以下方式实现：偏心轮张紧器用于张紧循环牵引装置。
由此，可以减小循环牵引装置(如例如链条)的冲击作用，并且避免NVH干扰。在安装时也有利的是，能够减小(电机与内燃机的)两个齿轮或皮带轮的两个旋转轴线之间的间隔，借此可以容易地装入循环牵引装置。
有利的实施方式在从属权利要求中要求保护，并且在下文中阐述。
因此有利的是：循环牵引装置构成为链条。与其他循环牵引装置、如例如皮带相比，链条可承受更大的力和力矩。因此，借助于链条可以将更大的扭矩从驱动设备传递给动力传动系的轴。
此外，已经证实为有利的是：偏心轮张紧器能够在其位置方面可变地紧固在混合动力模块壳体上，也就是说在围绕偏心轮旋转轴线运动时，偏心轮张紧器可以在不同位置中紧固在壳体上。因此，可以调整齿轮(或皮带轮)的两个旋转轴线之间的间隔，循环牵引装置围绕所述齿轮(或皮带轮)运行，以便个体化地且尽可能精确地调节循环牵引装置的张紧力。为此有利的是：连接轴的旋转轴线相对于偏心轮张紧器的旋转轴线错开。由此，在偏心轮张紧器围绕其旋转轴线旋转时，改变连接轴的旋转轴线相对于驱动轴的旋转轴线的间隔。
一个有利的实施方式提出，偏心轮张紧器划分成第一偏心轮构件和与其分开的第二偏心轮构件，例如沿着正交于连接轴的旋转轴线或偏心轮张紧器的旋转轴线延伸的平面划分。这种划分使得能够简化混合动力模块的安装或组装。
在此，有利的是：第一偏心轮构件与第二偏心轮构件旋紧。旋紧是可拆卸连接，通过所述可拆卸连接同样简化了偏心轮张紧器的拆卸。
已经证实为有利的是：混合动力模块壳体具有至少一个长孔、优选地两个长孔，以用于引导偏心轮张紧器的相对运动。在此，一个长孔或多个长孔有助于，引导偏心轮张紧器相对于壳体运动，并且因此简化偏心轮张紧器的定位。
在此，与长孔组合在如下情况下是有利的：偏心轮张紧器具有至少一个调整螺钉、优选地两个调整螺钉，以用于确定在混合动力模块壳体上的位置。所述调整螺钉插过长孔并且与偏心轮张紧器旋紧。通过拧紧或松开螺钉，可以要么紧固要么改变偏心轮张紧器的位置，其中，螺钉在长孔中引导，并且因此引导偏心轮张紧器相对于壳体的运动。
另一有利的实施方式提出，连接轴具有齿环，与连接轴相比，所述齿环具有更大的外径，并且所述齿环优选地与连接轴一件式实施。齿环与连接轴一件式的实施方案提高了稳定性，进而提高了可传递的力和力矩。
此外，本发明也涉及一种用于机动车辆的具有电机和内燃机的动力传动系，所述电机和内燃机经由根据本发明的混合动力模块彼此连接。
换言之，本发明在于开发一种系统，所述系统可以调整两个齿轮旋转轴线之间的间隔，并且确保系统的密封。在此，所述系统由偏心轮原理构成。在这种情况下，偏心轮本身两件式构成，并且支承用于电机如例如电动机的轴。发动机侧的偏心轮件、也就是说偏心轮的设置在电机侧上的部件在混合动力模块的发动机侧的壳体部件中在外径处安置并且定心。在所述位置处，密封件同样设有O形环，这是已知并且可靠的密封原理。变速器侧的偏心轮件、也就是说偏心轮的设置在变速器侧上的部件旋紧在发动机侧的偏心轮件上，并且确定偏心轮相对于壳体的轴向位置，并且由此也确定(连接)轴在混合动力模块中的轴向位置。所述两个壳体件的密封借助平坦的金属卷边膜来实施。电机旋紧在发动机侧的偏心轮件上。为了能够在运行中传递电机上的动态负载，电机同样通过发动机组上的保持机构连接。
发动机侧的偏心轮件此外在外部区域中具有孔。使用所述孔，以便调整偏心轮，进而在组装后将循环牵引装置、如例如链条张紧到特定的力。偏心轮在壳体中围绕其座(即围绕其旋转轴线)旋转，以便增加齿轮的两个旋转轴线之间的间隔。
同样地，发动机侧的偏心轮件旋紧在壳体上，在这种情况下，旋紧两次。为了能够实现调整偏心轮，两个螺钉安装到壳体中的长孔中。在张紧时必须使所述螺钉松开。当达到螺钉的特定张紧力时，可以再次牢固地旋紧两个螺钉。此外计划，在车辆检查时控制张紧力，并且必要时再次拉紧偏心轮。因此，张紧孔和两个调整螺钉能够在车辆中触及。
因此，也可以说，根据本发明，在轴线平行的混合动力模块中设有两件式的偏心轮。偏心轮的第一部件与内燃机的壳体的外侧可调节地连接。电机与偏心轮的所述第一部件连接。偏心轮的第二部件与偏心轮的第一部件连接。在偏心轮的第一部件与内燃机的壳体之间设有O形环。在内燃机的壳体与变速器的壳体之间设有密封膜，变速器的所述壳体容纳偏心轮的第二部件。
附图说明
在下文中借助于附图详细阐述本发明，在附图中示出不同的实施方式。附图示出：

图7示出混合动力模块的立体截面图。
附图仅仅是示意性的，并且仅用于理解本发明。相同的元件设有相同的附图标记。
具体实施方式
各个实施例的特征也可以在其他的实施例中实现。因此所述特征可彼此交换。
图1示出根据本发明的混合动力模块1的前视图。在图2中更清楚地看出，在混合动力模块1中，驱动轴2和连接轴3经由循环牵引装置4以传递扭矩的方式连接。为了能够预紧循环牵引装置4，设有偏心轮张紧器5。循环牵引装置4在此示例性地构成为链条6。所述链传动装置也称为主链传动装置。在图2中同样可看出副链传动装置7。混合动力模块1具有混合动力模块壳体8，所述混合动力模块壳体两件式构成。第一混合动力模块壳体部件也称为发动机侧的混合动力模块壳体部件9，并且第二混合动力模块壳体部件也称为变速器侧的混合动力模块壳体部件10。
偏心轮张紧器5同样两件式实施，并且具有第一(发动机侧)偏心轮构件11以及第二(变速器侧)偏心轮构件12。两个偏心轮构件11、12借助于多个连接螺钉13彼此连接。图3从与图2相反的一侧示出混合动力模块1。在此也描绘发动机侧的混合动力模块壳体部件9。在此也可良好地看出第一偏心轮构件11的形状。不仅在图2中而且在图3中可看出紧固孔14。可以将外部构件例如钩子等安置在所述孔14处，以便使偏心轮构件11或偏心轮5围绕其旋转轴线15(为此也参见图4)旋转。如果达到偏心轮或偏心轮张紧器5的期望位置，则偏心轮张紧器5经由调整机构16相对于混合动力模块壳体8紧固。
在图2中，调整机构16在示例性的实施方式中示出。调整机构16包括在混合动力模块壳体8中构成的两个长孔17以及两个调整螺钉18，所述调整螺钉在长孔17中引导并且与偏心轮张紧器5旋紧。图1示出，调整螺钉18的头部在直径方面大于长孔的宽度，由此调整螺钉支撑在混合动力模块壳体8上。
在图3中还可看出，偏心轮张紧器5具有多个旋拧孔19，所述旋拧孔用于拧紧电机20(也参见图4)。
图4示出混合动力模块1的纵截面视图，所述纵截面视图非常良好地表明所述混合动力模块的组装。可看出，偏心轮张紧器5两件式构造，其中，两个构件11、12经由连接螺钉13彼此旋紧。发动机侧的偏心轮构件11在外径处定心在发动机侧的混合动力模块壳体部件9处，并且经由O形环21密封。此外可看出，两个混合动力模块壳体部件9、10经由连接螺钉22彼此旋紧。两个混合动力模块壳体部件9、10经由密封膜23密封。在图4中的截面图中示出电机20以及内燃机(未示出)的曲轴24。
内燃机的旋转轴线25同时是第一齿环26的旋转轴线，链条6在所述第一齿环上运行。电机20的旋转轴线27同时是第二齿环28的旋转轴线。在此所示的实施例中，第二齿环28与连接轴3一件式构成，并且与第一齿环26相比，具有更小的直径。链条6不仅在第一齿环26上而且在第二齿环28上运行，并且因此将连接轴3与驱动轴2以传递扭矩的方式彼此连接。
在偏心轮张紧器5的内部，连接轴3经由两个轴承29、30支承，以便能够相对于偏心轮张紧器5旋转。偏心轮张紧器5的旋转轴线15与电机20的旋转轴线28错开地设置。由此可行的是，如在图5中图解说明的那样，电机20的旋转轴线28与内燃机的旋转轴线25之间的间隔借助于偏心轮张紧器5围绕其旋转轴线15的旋转来调整。为此，在松开调整螺钉18之后，将沿着所绘制的箭头作用的张紧力F施加到紧固孔14中。张紧力F促使偏心轮张紧器5围绕其旋转轴线15旋转，这通过调整路径W阐明。调整路径W一次作为围绕旋转轴线15的旋转阐明，并且两次作为调整螺钉18的通过长孔17引导的运动阐明。所述调整路径W促使电机20的旋转轴线27向外运动，这引起链条6的张紧，该旋转轴线在在此示出的位置中处于所谓的零位置(起始位置)中。
再次参考图4可看出，电机20的输出轴或从动轴可以经由轴-毂区域31以传递扭矩的方式与连接轴3连接。
图6和图7示出立体截面图，其中，图7示出图4的纵截面视图的立体示图，并且图6描绘靠近连接轴3和偏心轮张紧器5的区域的在图7中示出的立体截面视图的放大的局部视图。
在此可看出，偏心轮张紧器5容纳在混合动力模块壳体9中，使得偏心轮张紧器可以相对于所述混合动力模块壳体旋转，并且仅能够经由调整机构16在偏心轮张紧器的位置方面相对于混合动力模块壳体8紧固。
