Description

混合动力传动系
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，该混合动力传动系包括：驱动单元，该驱动单元具有内燃发动机、电机以及操作性地布置在内燃发动机与电机之间的分离式离合器；变速器；以及液力扭矩变换器，该液力扭矩变换器布置在变速器与驱动单元之间。
背景技术
通用混合动力传动系例如从DE 10 2012 221 618 A1、DE 10 2018 126 076A1、WO2008/064633 A1和WO 2016/060792 A1中是已知的。在此，混合动力驱动单元由内燃发动机和电机形成，其中，内燃发动机的曲轴和电机的转子可以借助于分离式离合器彼此连接。转子以不可旋转的方式连接至液力扭矩变换器的壳体，液力扭矩变换器的输出毂以不可旋转的方式连接至变速器的变速器输入轴。变速器——例如设计为自动变速器——例如经由差速器来驱动机动车辆的驱动轮。为了隔离扭振，集成在扭矩变换器的壳体中的扭振阻尼器从公开WO 20126/060792中是已知的。
发明内容
本发明的目的是进一步开发一种通用混合动力传动系。特别地，本发明的目的是改善通用混合动力传动系的扭振隔离。
公开的混合动力传动系意在用于具有混合动力操作、全电动操作以及纯内燃发动机操作的机动车辆。为此目的，混合动力传动系包括驱动单元，该驱动单元具有内燃发动机和电机，其中，在内燃发动机与电机之间操作性地布置有分离式离合器。在分离式离合器闭合的情况下，例如可以以混合动力操作模式驱动、可以从电机启动内燃发动机或者可以借助于电机的再生操作从内燃发动机对电能储存装置比如蓄电池进行充电。当分离式离合器打开时，例如可以以全电动驱动模式驱动或者可以进行回收。
在电机的转子的下游，即变速器例如自动变速器的下游，或者在变速器与驱动单元之间操作性地布置有液力扭矩变换器。液力扭矩变换器容纳在壳体、比如变换器壳体中，其中，连接至变换器壳体的泵轮驱动涡轮机叶轮。导引轮可以设置在泵轮与涡轮机叶轮之间以在较低速度、例如以机动车辆的启动速度时增加扭矩。变换器锁止离合器可以布置在变换器壳体与扭矩变换器的输出毂之间以桥接扭矩变换器，特别是在启动过程之后和/或在用于提高回收的推动力下的较高速度时。
输出毂有利地以在扭转方面锁定的方式连接至变速器的变速器输入轴。变速器具有若干个齿轮或变速顺序，并且变速器输出轴借助于差速器和/或全轮驱动系统的分动箱来将扭矩传递至驱动轮。
为了隔离受扭振影响的内燃发动机的扭振，在曲轴与分离式离合器之间可以布置有扭振阻尼器、例如双质量件飞轮。在这种扭振阻尼器中可以集成有离心摆。替代性地或另外地，可以将至少一个扭振阻尼器集成到变换器壳体中。例如，这种扭振阻尼器可以在变换器壳体与变换器锁止离合器之间起作用。替代性地或另外地，扭振阻尼器可以操作性地布置在涡轮机叶轮与输出毂之间。这种扭振阻尼器或这些扭振阻尼器可以具有离心摆。
根据本发明的构思，至少一个扭振吸收器替代性地或另外地布置在驱动单元与扭矩变换器的壳体之间。扭振吸收器是下述装置：在该装置中，相对于承载部分接纳有能够在周向方向上移位的至少一个吸收器质量件。例如，所述至少一个扭振吸收器可以设计为质量件吸收器，其中，在周向上分布的至少一个、优选地多个吸收器质量件被接纳在承载部分上以便能够相对于承载部分抵抗在周向方向上作用的弹簧装置的作用而绕混合动力传动系的旋转轴线旋转有限的程度。替代性地或另外地，所述至少一个扭振吸收器可以设计成适应于旋转速度、例如设计为呈离心摆的形式或者设计为环形质量件吸收器。
在离心摆中，形成为摆质量件的吸收器质量件借助于摆轴承安装在绕旋转轴线旋转的承载部分的离心力区域中，以便能够相对于承载部分摆动。承载部分可以设计为摆凸缘，摆质量件接纳在摆凸缘上的两个侧部上，其中，轴向相对的摆质量件连接至彼此以形成摆质量件单元。摆轴承可以形成在摆质量件与摆凸缘之间，其中，摆滚子轴向地接合在摆质量件和摆凸缘的滚动表面上并且在后者上滚动。替代性地，摆轴承可以形成在将接纳在摆凸缘的凹部中的轴向相对的摆质量件连接的中央部分与摆凸缘之间。摆轴承由中央部分和摆凸缘的滚道形成，中央部分和摆凸缘在径向上位于彼此之上并且在轴向上是同轴的，其中，摆滚子在它们中的每一者上滚动。
替代性地，承载部分可以由两个轴向间隔且相互连接的部段、例如相互连接的侧部部分形成，其中，在周向上分布的摆质量件被轴向地接纳在这些部段之间。摆轴承由在部段以及摆质量件中机加工的滚道形成，其被在滚道上滚动的摆滚子轴向地重叠。
环形质量件摆由可以相对于彼此旋转的两个质量件部分形成，其中，一个质量件部分形成支承部分并且另一个质量件部分形成环形质量件。摆质量件以分布在周向上的方式布置，其中，摆轴承布置在质量件部分中的一个质量件部分与摆质量件之间，并且轴承布置在另一个质量件部分与在周向方向上间隔开的摆质量件之间，其中，该轴承在周向方向上是刚性的并且允许摆质量件与质量件部分之间在径向方向上进行相对旋转。
根据混合动力传动系的有利实施方式，所述至少一个扭振吸收器布置在干燥环境中。以这种方式，所述至少一个扭振吸收器可以设计成很大程度上独立于扭矩变换器的壳体形状，并且例如在其扭振隔离性质具有缺陷、例如离心摆或环形质量件摆的吸收器顺序有缺陷的情况下，可以避免所述至少一个扭振吸收器的搅动损失。
形成为质量件吸收器的所述至少一个扭振吸收器可以设计成用于一种或更多种吸收器频率。设计成适应于旋转速度的所述至少一个扭振吸收器可以设计成用于单个或多个吸收器或内燃发动机的单个或多个激发顺序。应当理解的是，可以设置有若干个扭振吸收器，这些扭振吸收器被调整成不同的吸收器频率和或吸收器顺序。例如，还可以设置适应于旋转速度的扭振吸收器，该扭振吸收器根据摆质量件或质量件环的质量件的对应的不同设计、摆路径、摆轴承的振荡角度、摆重心至旋转轴线的半径等而设计成用于两个或更多个吸收器顺序。
所述至少一个扭振吸收器可以以不可旋转的方式连接至分离式离合器的输出部分并且连接至扭矩变换器的壳体。例如，分离式离合器可以在内燃发动机的停止过程期间打开，使得没有由内燃发动机在至少一个扭振吸收器上引发的冲击、即突然的扭矩变化作用在至少一个扭振吸收器上，这种突然的扭矩变化可以对特别地设计为离心摆的扭振吸收器造成损坏或者至少产生降低舒适度的噪音。另外，当内燃发动机在驱动时被关闭，变速器侧的旋转速度可以在所述至少一个扭振吸收器处被保持。当内燃发动机重启时，可以避免所述至少一个扭振吸收器的再加速。
扭矩变换器可以借助于位于内燃发动机与变速器之间的分隔壁来支承或居中。分隔壁可以轴向地布置在分离式离合器与扭矩变换器或扭矩变换器的变换器壳体之间。分隔壁可以接纳在变速器的变速器钟形壳体上。
例如，分离式离合器和所述至少一个扭振吸收器可以布置在分离式离合器的一侧上，并且扭矩变换器和扭矩变换器的变换器壳体以及电机可以布置在分离式离合器的另一侧上。优选地，电机布置在变换器壳体的外侧。定子可以接纳在变速器的变速器钟形壳体上。分离式离合器也可以进行干式操作。
分离式离合器可以径向地布置在接纳于曲轴上的扭振阻尼器的内侧。分离式离合器可以被液压地致动，例如借助于轴向地作用在优选地闭合的分离式离合器上的液压地移位的活塞被致动。
中央毂一方面可以以可旋转的方式安装在分隔壁上并且另一方面安装在变速器输入轴上。电机的转子以及扭矩变换器的变换器壳体可以以不可旋转的方式安装在该中央毂上并且在该中央毂上居中。以可旋转的方式围绕中央毂可以布置有另一个毂，所述另一个毂以不可旋转的方式接纳所述至少一个扭振吸收器的承载部分以及分离式离合器的输出部分。
附图说明
参照图1和图2中示出的示例性实施方式更详细地说明本发明。在附图中：
图1示出了混合动力传动系的上部部分的截面图；以及
图2示出了与图1中的混合动力传动系相比已修改的混合动力传动系的上部部分的截面图。
具体实施方式
图1示出了围绕旋转轴线d布置的混合动力传动系1的上部部分的截面图。混合动力传动系1的驱动部分2由内燃发动机3和电机5形成，仅内燃发动机的曲轴4部分地示出，内燃发动机和电机在空间上彼此分隔开并且可以借助于分离式离合器6彼此连接。
直接连接至曲轴4的是第一扭振阻尼器7的输入部分8，扭振阻尼器的输出部分9布置成能够相对于输入部分8抵抗以封装形式接纳在输入部分8中的弹簧装置10的作用而旋转至有限的程度并且以不可旋转的方式在分离式离合器6的输入毂11上居中。
输入毂11以在旋转方面锁定的方式接纳分离式离合器6的离合器盘12并且被接纳在离合器毂13上以便能够旋转。离合器盘12通过其布置在两侧上的摩擦衬片与分离式离合器6的输出部分14形成摩擦接合，分离式离合器的输出部分包括轴向固定的背压板15和可轴向移位的压力板16。压力板16通过可液压移位的活塞17在轴向上进行作用，该活塞根据施加在压力室18中的压力而移位。分离式离合器6设计为闭合离合器并且在径向上布置在第一扭振阻尼器7的弹簧装置10的内侧。
分离式离合器6的输出部分14以不可旋转且居中的方式安装在离合器毂13上。
扭振吸收器19以不可旋转的方式安装在分离式离合器6的输出部分14上。扭振吸收器19在此形成为质量件吸收器20，质量件吸收器的承载部分21借助于从输出板22突出的铆钉23以不可旋转的方式连接至输出部分14。吸收器质量件24、25布置在承载部分21的围绕周向分布的两个侧部上。螺旋压缩弹簧26沿周向方向操作性地布置并且在吸收器质量件24、25与承载部分21之间分布在周向上，螺旋压缩弹簧中的每个螺旋压缩弹簧在端部处通过承载部分21和吸收器质量件24、25进行作用。吸收器质量件24、25在承载部分21的外侧径向地彼此连接，其中，例如，吸收器质量件24轴向地折叠在吸收器质量件25的径向外侧上并焊接至吸收器质量件25。应当理解的是，周向分布的吸收器质量件24、25可以在周向方向上连接至彼此以形成环形的吸收器质量件。
分离式离合器6和扭振吸收器19布置在变速器的变速器钟形壳体28的干燥空间27中，干燥空间未详细示出。干燥空间27在变速器的方向上借助于轴向固定的分隔壁29来定界。分隔壁29附接至、例如螺栓连接或销连接至变速器钟形壳体28的肩部30。分隔壁29借助于轴承31以轴向固定且可旋转的方式径向向内地接纳中央毂32。中央毂32和离合器毂13以不可旋转的方式连接至彼此。此外，电机5的转子33以及液力扭矩变换器35的变换器壳体34通过中央毂32以不可旋转且居中的方式接纳在分隔壁29的与分离式离合器6和扭振吸收器19相反的一侧上。以这种方式，变速器的变速器输入轴36被缓解并且在变速器钟形壳体28上形成有支承部，电机5的定子37也被接纳并居中在变速器钟形壳体上。
变换器壳体34接纳扭矩变换器35的泵轮38，泵轮流体动力地驱动涡轮机叶轮39。在电机5的径向内部以及变换器壳体34的径向内部，在扭矩变换器35的变换器壳体34与输出毂41之间定位有变换器锁止离合器40。一方面在变换器锁止离合器40的输出部分与输出毂41之间，并且另一方面在涡轮机叶轮39与输出毂41之间操作性地布置有第二扭振阻尼器42，并且因此扭振阻尼器用作所谓的锁止阻尼器和涡轮机阻尼器。输出毂41以不可旋转的方式连接至变速器输入轴36。
这使得在分离式离合器6闭合时扭矩从内燃发动机3的曲轴4经由第一扭振阻尼器7和在扭振吸收器19的作用下的分离式离合器6、经由离合器毂13流动至中央毂32。如果需要的话，附加的扭矩经由转子33传递至中央毂32。该扭矩经由扭矩变换器35传递至变速器输入轴36，或者如果扭矩变换器锁止离合器40闭合，则经由该扭矩变换器锁止离合器通过经由输出毂41插入的第二扭振阻尼器42传递至变速器输入轴。根据接合在变速器中的齿轮，扭矩以适当的旋转速度在变速器输出轴处经由差速器传递至驱动轮。
当分离式离合器打开时，机动车辆可以在电动驱动模式下通过混合动力传动系1借助于电机5被专门地驱动或者可以进行回收。如果内燃发动机3在过程中停止，则扭振吸收器19以变速器速度继续旋转使得其不会经受在内燃发动机停止或重新启动时导致噪音或过度负荷的任何突然的加速度变化。
图2示出了围绕旋转轴线d布置的混合动力传动系1a的上部部分的截面图，该混合动力传动系与图1的混合动力传动系1类似。与混合动力传动系1相比，混合动力传动系1a具有扭振吸收器19a，该扭振吸收器设计成适应于旋转速度并且在此形成为离心摆20a。离心摆20a借助于离心摆的承载部分21a固定地连接、例如借助于铆钉凸台23a固定地连接至分离式离合器6a的输出部分14a的输出板22a。
在示出的示例性实施方式中，离心摆20a包括吸收器质量件24a、25a，吸收器质量件布置在承载凸缘21a的两个侧部上并且形成为摆质量件43a、44a。摆质量件43a、44a根据相对于承载部分21a沿着预定摆路径形成在承载部分21a与摆质量件43a、44a之间的摆轴承45a悬挂在绕旋转轴线d旋转的承载部分21a的离心力区域中。
摆轴承45a各自由两个轴向相对、相互连接的摆质量件43a、44a以及承载部分21a形成，其中，在这些摆轴承的每一者中设置有具有滚道的凹部，到达滚道上的摆滚子46a在滚道上滚动。
