混合动力汽车传动装置
技术领域
本发明涉及混合动力汽车传动装置，该混合动力汽车传动装置具有：齿轮变速器和电机，该齿轮变速器用于建立变速器输入与变速器输出之间的至少一个传动比，其中，齿轮变速器具有齿轮组，该齿轮组包括联接齿轮，该电机具有电机输出轴，该电机输出轴具有驱动齿轮，该驱动齿轮直接地或经由联接齿轮组联接至变速器齿轮组的联接齿轮，使得建立了从电机输出轴至联接齿轮的动力传输路径。
背景技术
从DE102012009484C已知这种混合动力汽车传动装置。在此，齿轮变速器为具有多个传动比的双离合器变速器。电机经由联接齿轮连接至双离合器变速器的副变速器中的一个副变速器的输入。在这种布局中，能够实现各种混合动力模式，包括：纯电力驱动、增强操作、恢复等。电动马达的至变速器齿轮组的联接齿轮的连接能够确保传动布局的轴向紧凑设计，这是因为在齿轮变速器中，电机的连接不需要单独的齿轮。
为此，在现有技术中提出：或者将电机永久地连接至联接齿轮，或者经由接合离合器将电机连接至联接齿轮。接合离合器使得能够或者将电机连接至联接齿轮，或者将电机与联接齿轮断开连接。将电机与联接齿轮断开连接的状态设计成例如用以减小拖曳损耗等。
在任何情况下，混合动力汽车传动布局中的部件设计成吸收在任何时间发生的最大力或力矩。由于力或力矩会是较大的，所以个体部件需要定尺寸为相对较大。
发明内容
在上下文中，本发明提出要解决的一个问题是指示改进的混合动力汽车传动布局，这种改进的混合动力汽车传动布局使得能够将至少一个部件设计得更小并且/或使得能够保护至少一个部件免受过载。
以上问题在上文提到的混合动力汽车传动布局中得到解决，因为在动力传输路径中设置有滑动离合器。
滑动离合器能够为齿轮变速器实现过载保护，尤其是为将电机连接至齿轮变速器的齿轮组实现过载保护。此外，位于动力流中的部件能够设计或定尺寸成使得它们不必经受所有可能发生的一个或更多个力或扭矩峰值。作为替代，所述部件能够优选地定尺寸或设计成使得它们能够基本上传递或经受调整(orientedto)为电机的特征力矩(比如额定力矩)的扭矩。
即，在变速器输出的急剧减速期间并且考虑到电机的惯性，上文提到类型的混合动力汽车传动布局中会产生较大的反作用力矩。这些反作用力矩可以是额定力矩的许多倍。通过在动力传输路径中设置滑动离合器，能够保护部件免受过载，而该过载可能导致损坏部件。
例如通过各种制动操纵和/或当锁定驻车制动器时，由于这会导致变速器输出的急剧减速，会产生上文提到的反作用力矩。
电机能够通过法兰在外侧连接至齿轮变速器，但电机还能够设置在变速器中，即，电机集成在齿轮变速器的壳体内侧。电机可以在这种情况下被冷却。
由于在动力传输路径中设置了滑动离合器，所涉及的部件能够定尺寸为更小，例如在轴直径方面、在齿轮宽度方面、在齿轮和/或轴材料方面、在轴承大小方面等定为更小。
优选地，在动力传输路径中不设置其他的联接件，比如不设置接合离合器，但可设想到将这种接合离合器以与滑动离合器串联或并联的方式设置。
齿轮变速器优选地为双离合器变速器，但齿轮变速器还可以是桥驱动装置、具有转换器的自动变速器等。
滑动离合器优选地为扭矩切换离合器，特别地是摩擦离合器，该滑动离合器设计成通过特定摩擦锁定来操作。滑动离合器优选地为被动式自切换联接件，而不是致动器启动式联接件。当然，滑动离合器优选地设计成能够传递最高达扭矩阈值的扭矩并且当存在大于扭矩阈值的扭矩时能够断开，即，滑动离合器不传递扭矩的至少超过阈值的部分。
扭矩阈值设计成使得在正常操作期间，贯穿动力传输路径传递的扭矩不超过该阈值。然而，阈值小于例如当变速器输出急剧减速时产生呈反作用力矩形式的扭矩。
因此，完全解决了该问题。
特别有益的是将滑动离合器设计成过载保护离合器，使得滑动离合器能够传递最高达扭矩阈值的扭矩，其中，该扭矩阈值是电机的特征扭矩值的函数。
特别地，特征扭矩值为电机的额定扭矩，但特征扭矩值也可以是电机的最大扭矩。
在任何情况下，滑动离合器设计成使得动力传输路径的额定扭矩能够被安全地传递。
根据另一实施方式，滑动离合器构造为过载保护离合器，使得滑动离合器能够传递最高达扭矩阈值的扭矩，其中，该扭矩阈值为联接齿轮的最大扭矩的函数。
换言之，阈值还可以由能够通过联接齿轮传递的最大扭矩有多高来确定。优选地，阈值既取决于该最大扭矩又取决于电机的特征扭矩值。
根据另一优选实施方式，在电机输出轴与联接齿轮之间建立联接传动比，其中，扭矩阈值是联接传动比的函数。
通常，联接传动比设计成将电机的高旋转速度转换为联接齿轮的低旋转速度，使得电机能够优选地在更高的旋转速度范围内操作。以这种方式，一般来说电机能够在设计方面更紧凑。
扭矩阈值优选地不仅取决于联接传动比，而且取决于滑动离合器在动力传动路径中设置的位置，即，设置在电机输出轴附近、或设置在联接齿轮附近、或设置在位于电机输出轴与联接齿轮之间的区域中。
此外，总体上，对于滑动离合器而言，优选地是具有至少一个摩擦渐缩式配对件。
另一方面，通过这种摩擦渐缩式配对件或摩擦锥形系统，能够生产经济型滑动离合器。此外，这种摩擦渐缩式配对件能够相对容易且紧凑地结合在动力传输路径中。
摩擦渐缩式配对件的锥角优选地小于20°，特别地小于10°，并且优选地大于3°，特别地大于5°。
特别优选地是，摩擦渐缩式配对件具有位于第一扭矩传递元件处的第一摩擦锥形部以及位于第二扭矩传递元件处的第二摩擦锥形部，其中，第一扭矩传递元件和第二扭矩传递元件通过弹簧机构而被偏置。
在这种情况下，能够通过下述方面来调节扭矩阈值：通过选择锥角角度，通过预张紧(该预张紧特别地沿轴向方向延伸)的幅度，并且还通过第一摩擦锥形部和第二摩擦锥形部的尺寸和材料以及表面质量。
例如可以以在汽车变速器的同步换挡离合器中同样惯用的方式实现锥形座和环，例如通过使用由黄铜等制成的锥形摩擦环。特别地，弹簧机构可以是环形盘式弹簧机构，该环形盘式机构优选地为标准部件，以便降低成本。
弹簧机构沿着轴向方向优选地抵靠径向突出部被支撑，该径向突出部以轴向地并且优选地旋转地稳固方式连接至轴。特别优选的是，弹簧机构沿轴向方向抵靠于固定至轴的另一个齿轮而被支撑。
此外，有利的是，第一扭矩传递元件为摩擦渐缩环，而第二扭矩传递元件为摩擦渐缩齿轮，特别地为驱动齿轮或联接齿轮组的齿轮。
以这种方式，由于扭矩传递元件中的一个扭矩传递元件为无论如何存在为将电机与联接齿轮连接的齿轮，因此能够通过较少的附加部件实现摩擦渐缩式配对件。然而，摩擦渐缩式齿轮当然可以被修改成在其上形成摩擦渐缩部，或将摩擦渐缩部紧固在其上。
在一种变型中，摩擦渐缩齿轮被刚性地接合至轴。在这种情况下，摩擦渐缩环能够通常相对于轴转动并且通过弹簧机构而压靠摩擦渐缩齿轮的摩擦渐缩部。例如当扭矩阈值相对较低时，能够使用这种简单的摩擦渐缩式系统。
在替代性实施方式中，摩擦渐缩环以稳固地防旋转的方式接合至轴的一部分，但优选地是，摩擦渐缩环能够相对于轴部分轴向地移动。
在该实施方式中，摩擦渐缩齿轮优选地关于轴部分被可旋转地支承，和/或摩擦渐缩齿轮能够轴向地固定在轴部分上。
然而，在摩擦渐缩齿轮以稳固地防旋转的方式接合至轴的实施方式中，摩擦渐缩部优选地形成在摩擦渐缩齿轮的外周向部上，在本变型中，优选地是，摩擦渐缩齿轮的摩擦渐缩部形成在摩擦渐缩齿轮的内圆周上。
摩擦渐缩环优选地沿径向方向设置在摩擦渐缩齿轮与轴部分之间。
如上文提到的，通常可设想的是，滑动离合器由单个摩擦渐缩式配对件形成。
然而，特别有益的是，摩擦渐缩齿轮具有两个摩擦渐缩部，每个摩擦渐缩部被分配摩擦渐缩环，该摩擦渐缩环以稳固地防旋转的方式接合至轴部分。
摩擦渐缩环优选地能够相对于轴部分轴向地移动。
在该实施方式中，滑动离合器由双渐缩系统形成。
摩擦渐缩齿轮的摩擦渐缩部优选地以相对于轴的轴线的两个对角设置，即以X形布置的方式设置。
通常可设想到将弹簧机构分配至摩擦渐缩环中的每个摩擦渐缩环，摩擦渐缩环通过弹簧机构抵抗摩擦渐缩齿轮的摩擦渐缩部而沿着两个相反的轴向方向被偏置。
然而，特别有益的是，摩擦渐缩环中的一个摩擦渐缩环轴向地紧固在轴部分上，弹簧机构布置在另一个摩擦渐缩环与接合至轴部分的径向部分之间。
在该实施方式中，使用仅单个弹簧机构以便实现滑动离合器的轴向预张紧。与轴部分接合的径向部分优选地为齿轮的与轴部分接合的径向部分。
此外，整体上有利的是，摩擦渐缩齿轮为安装在电机输出轴上的驱动齿轮。
在替代性实施方式中，联接齿轮组具有第一中间齿轮和与第一中间齿轮同轴地设置的第二中间齿轮，而摩擦渐缩齿轮为第一中间齿轮和/或第二中间齿轮。
在该实施方式中，联接齿轮组优选地具有中间轴，两个中间齿轮设置在中间轴上，然而优选地，两个中间齿轮中的一个中间齿轮为摩擦渐缩齿轮，而另一个中间齿轮优选地是稳固地防旋转并且特别地与中间轴形成为单件。
本发明的滑动联接能够特别地限制动力传输路径中的可传递扭矩。与对经受更高载荷——该更高载荷由大质量惯性的反作用力矩造成——的齿轮部件进行强化相比较，解决方案优选地提供对具有略微附加重量的齿轮部件的保护。因此，具有滑动离合器的本发明的解决方案还能够具有成本效益。
滑动离合器可以还具有多盘式离合器以替代摩擦渐缩式配对件。在这种情况下，与一个或更多个摩擦渐缩式配对件的情况相比，轴向偏置力更小，而另一方面，需要通过内花键和外花键的更精细的旋转传输。滑动离合器还能够通过多锥形(multitaper)摩擦系统来形成，在这种情况下，轴向偏置力可以更小。作为盘簧的替代，还可以使用筒形压缩弹簧或弯曲弹簧。
优选地，滑动离合器设置在中间轴上，其中，在中间轴上安装有两个齿轮。一个齿轮可以通过滚针轴承安装在中间轴上，该中间轴特别地构造成为双齿轮轴。齿轮中的一个齿轮还可以构造为中空轴齿轮，其中，齿轮形成中间轴。
当然，在不偏离本发明的范围的情况下，上述的和仍要描述的特征不仅能够以特别指示的组合来使用，而且能够以其他的组合或单独地来使用。
附图说明
本发明的示例实施方式在附图中呈现并且在以下描述中被更清楚地说明。附图中：
图1为具有根据本发明的混合动力汽车传动布局的一种实施方式的机动车辆的传动系的示意性图示，其中，电机能够经由联接齿轮组联接至联接齿轮；

具体实施方式
图1示出了机动车辆11的传动系10的示意图。
传动系10包括驱动马达12比如内燃机，该驱动马达12的输出轴连接至双离合器装置14的输入。双离合器装置14的输出连接至双离合器变速器16的输入装置。双离合器变速器16的输出连接至差速器18，该差速器18将驱动力分配至两个从动轮20L、20R。
传动系设计成用于横向安装，尤其是用于在机动车辆11中的前横向安装。
双离合器变速器16包括第一输入轴24以及第二输入轴26，该第一输入轴24设计为实心轴，该第二输入轴26设计为与第一输入轴24同心的中空轴。第一输入轴24连接至双离合器装置14的第一离合器28的输出元件。第二输入轴26连接至双离合器装置14的第二离合器30的输出元件。
此外，双离合器变速器16包括第一副轴32和第二副轴34，所述第一副轴32和第二副轴34以与输入轴24、26平行且错开的方式设置。副轴32、34通过驱动齿轮组36连接至差速器18。驱动齿轮组36包括：第一固定齿轮38，该第一固定齿轮38接合至第一副轴32；以及另一个固定齿轮40，所述另一个固定齿轮40接合至第二副轴34。两个固定齿轮38、40与差速器18的驱动齿轮42接合。
从双离合器变速器16的与变速器输入相反的轴向端部观察时，在第一变速器输入轴24上安装有：用于前进档1的第一固定齿轮44、用于前进档3的第二固定齿轮46以及用于前进档5和7的第三固定齿轮48。以对应的形式，从与变速器输入相反的轴向端部观察时，在第二输入轴26上安装有：用于前进档4和6的第一固定齿轮50，以及用于前进档2和倒档R的第二固定齿轮52。
再从与变速器输入相反的一端看时，在第一副轴32上安装有用于前进档1的第一惰轮54、用于前进档7的另一个惰轮56、用于前进档6的另一个惰轮58以及用于前进档2的另一个惰轮60，并且能够使这些部件旋转。用于前进档2的惰轮60稳固地连接至辅助齿轮62，该辅助齿轮62用于实现倒档R，如下文说明的。
再从与变速器输入相反的一端观察时，在第二副轴34上安装有用于前进档3的第一惰轮64、用于前进档5的另一个惰轮66、用于前进档4的另一个惰轮68以及用于倒档R的另一个惰轮70，并且能够使这些部件旋转。
驱动齿轮组36的固定齿轮38、40设置成与变速器输入相邻，而在第二副轴34上在固定齿轮40与用于倒档R的惰轮70之间安装有驻车制动齿轮72。驻车制动齿轮72相对于用于前进挡2的惰轮60沿轴向方向定向。
在惰轮54、56之间设置有第一换挡离合器组件76，第一换挡离合器组件76具有两个换档离合器以用于将前进档1和前进档7接合和分离。在用于前进档6的惰轮58和用于前进档2的惰轮60之间设置有用于将这些前进档接合和分离的第二换挡离合器组件78。
在第二副轴34上，在用于前进档3的惰轮64与用于前进档5的惰轮66之间设置有用于将这些前进档接合和分离的第三换挡离合器组件80。最后，在第二副轴34上，在用于前进档4的惰轮68与用于倒档R的惰轮70之间设置有用于将这些档位接合和分离的第四换挡离合器组件82。
固定齿轮44处于与惰轮54接合。固定齿轮46处于与惰轮64接合。固定齿轮48处于与惰轮56、66接合。固定齿轮50处于与惰轮58、68接合。固定齿轮52处于与惰轮60接合。
辅助齿轮62处于与用于倒档R的惰轮70接合，以便以这种方式在不必设置单独辅助轴的情况下实现反向转动。
用于前进档3的齿轮组46、64沿轴向方向设置在用于前进挡1的齿轮组54、44与换挡离合器组件76之间。出于这种目的，惰轮54通过短轴84连接至第一换挡离合器组件76。
驻车制动齿轮72用于实现驻车制动装置P，该驻车制动装置P具有例如驻车制动爪(不再另外示出)。
在双离合器变速器16中，对于档位5、7和档位4、6而言，实现了两个双模式用途。此外，驻车制动齿轮72相对于用于前进档2的惰轮60轴向地定向。整体上，以这种方式能够实现轴向紧凑的设计。能够通过辅助齿轮62来调节用于倒档R的适当传动比。
电机90连接至用于前进档4的惰轮68。因此，该惰轮68用于使双离合器变速器16实现混合动力操作。电机90具有输出轴91，该输出轴91以与轴24、26、32、34平行的方式定向并且连接至齿轮92。齿轮92处于与用于前进挡4的惰轮68接合，使得形成从输出轴91至惰轮68的动力传输路径93，从而在本情况下惰轮68形成联接齿轮。在该实施方式中的驱动齿轮92直接地联接至联接齿轮(惰轮68)。作为这种情况的替代，还能够将驱动齿轮92与双离合器变速器16中的另一个齿轮联接。作为一种示例，示出了驱动齿轮92还能够处于与第一固定齿轮50接合，使得第一固定齿轮50形成了联接齿轮。在这种情况下，形成了从电机输出轴91至齿轮50的动力传输路径93’。
作为这种情况的替代，能够将电机输出轴91连接至驱动齿轮，该驱动齿轮处于经由中间齿轮而与惰轮68接合，从而以这种方式形成联接齿轮组，该联接齿轮组由驱动齿轮和中间齿轮形成。
在图1中示意性示出的动力传输路径93中，即在电机输出轴91处设置有滑动离合器94。然而，滑动离合器94也能够设置在动力传输路径93中的其他任何位置。
滑动离合器94设计为过载保护离合器，其中，滑动离合器94能够传递最高达扭矩阈值的扭矩，该扭矩阈值为电机90的特征扭矩的函数、联接齿轮68(或50，例如)的最大扭矩的函数、和/或联接传动比的函数，其中，所述联接传动比形成在电机输出轴91与联接齿轮68(或50)之间。在扭矩阈值为联接传动比的函数的情况下，扭矩阈值还取决于滑动离合器94在动力传输路径93内设置的位置。
以下附图示出了在设计和操作方面与上文描述的布局基本上对应的汽车传动布局或其零部件的另一实施方式。因此，相同的元件由相同的附图标记表示。在下文中，主要讨论差异。
图2示出了电机90的经由动力传输路径93”至联接齿轮68(或50)的连接。动力传输路径93”具有联接齿轮组95。更精确地，电机输出轴91稳固地连接至驱动齿轮92。在辅助轴96上安装有辅助齿轮98，该辅助齿轮98处于与驱动齿轮92接合。此外，中间轴100设置成与辅助轴96平行，在中间轴100上安装有第一中间齿轮102和第二中间齿轮104。第一中间齿轮102处于与辅助齿轮98接合。第二中间齿轮104处于与联接齿轮68(或50)接合。
在该构型中，在中间轴100上，优选地在第一中间齿轮102与中间轴100之间形成有滑动离合器94’。替代性地，滑动离合器还可以形成在辅助齿轮98与辅助轴96之间，或形成在驱动齿轮92与电机输出轴91之间。
在下面的图3至图5中描绘了这种滑动离合器的设计示例，设计示例的构型中每个构型可以与上文描述的传动布局16相结合。
图3示出了安置于中间轴100与第一中间齿轮102之间的滑动离合器94”。第一中间齿轮102例如通过滚针轴承105可旋转地安装在中间轴100上。在该实施方式中，中间轴100以稳固地防旋转的方式连接至第二中间齿轮104并且能够特别地与第二中间齿轮104形成为单件。
滑动离合器94”包括安置于第一中间齿轮102与第一摩擦渐缩环108之间的第一摩擦配对件106。第一摩擦渐缩环108在此形成第一扭矩传递元件，并且第一中间齿轮102在此形成第二扭矩传递元件。第一摩擦配对件106包括位于第一摩擦渐缩环108的外圆周的一部分上的第一摩擦渐缩部110和位于第一中间齿轮102的内圆周的一部分上的第二摩擦渐缩部112。第一摩擦渐缩环108以稳固地防旋转的方式连接至中间轴100，但安装成使得第一摩擦渐缩环108例如通过花键等相对于中间轴100具有受限的轴向移动。
此外，滑动离合器94”通过另一个摩擦渐缩环108A而包括另一个摩擦配对件106A，在所述另一个摩擦渐缩环108A的外圆周上形成有另一个第一摩擦渐缩部110A。在第一中间齿轮102上，在内圆周上形成有另一个第二摩擦渐缩部112A，从而与所述另一个第一摩擦渐缩部110A形成另外的摩擦配对件106A。
摩擦配对件106、106A形成在第一中间齿轮102的轴向相反两端处。摩擦渐缩部的角度优选地在3°与20°之间的范围内，特别地在5°与10°之间的范围内，并且摩擦渐缩部的角度以与用于轴承的X形布置类似的方式沿着相反方向倾斜。
附加的摩擦渐缩环108A相对于中间轴100沿轴向方向由轴向紧固环114紧固。在第一摩擦渐缩环108与连接至中间轴100的径向部分118——在本情况下，径向部分118由第二中间齿轮104的径向部分形成——之间，设置有呈盘簧组件116形式的弹簧机构116。摩擦配对件106、106A通过轴向操作的弹簧机构116而被偏置。弹簧机构106的弹簧常数结合摩擦配对件106、106A的角度以及摩擦配对件的面积和所使用的材料确定了表征滑动离合器94”的扭矩阈值。
图4示出了相同的滑动离合器94”，但在这种情况下滑动离合器94”设置在驱动齿轮92与电机输出轴91之间，而在电机输出轴91上形成有径向部分118，该径向部分118不需要形成为齿轮。滑动离合器94”的弹簧机构116抵靠径向部分118被支撑。
图5示出了另一变型的滑动离合器94”’，该滑动离合器94”’可以设置在例如第一中间齿轮102与第二中间齿轮104之间。在该布局中，第一中间齿轮102以稳固地防旋转的方式接合至中间轴100’。第二中间齿轮104安装在中间轴100’上并且能够旋转，并且第二中间齿轮104由轴向紧固环114’在轴向方向上被紧固在中间轴100’上。
滑动离合器94”’包括单个摩擦配对件106”’，该摩擦配对件106”’安置于第一中间齿轮102或中间轴100与摩擦渐缩环108”’之间。摩擦渐缩环108”’具有位于其内圆周上的第一摩擦渐缩部110”’。在中间轴100’的外圆周的一部分或第一中间齿轮102的外圆周的一部分上形成有第二摩擦渐缩部112”’。在第二中间齿轮104与摩擦渐缩环108”’之间沿轴向方向设置有弹簧机构116，以使摩擦配对件106”’沿轴向方向偏置。
在所有的变型中，弹簧机构116可以设置在轴向凹部中(比如在例如在图3和图5中表示的)以便以这种方式优化设计空间。
尽管图3中的摩擦渐缩环108、108A相对于中间轴100以稳固地防旋转但能够轴向移动的方式安装，但摩擦渐缩环108”’相对于中间轴100’以既能够旋转又能够轴向移动的方式安装。
