Description

驱动单元
技术领域
本发明涉及尤其用于混合动力传动系的驱动单元，所述驱动单元具有内燃机，所述内燃机具有第一壳体和曲轴，并且所述驱动单元具有电机，所述电机具有第二壳体和转子，其中两个壳体彼此牢固地连接，并且曲轴和转子彼此旋转配合地连接。
背景技术
对于混合动力传动系，例如从出版物DE100 25 853 A1中已知一种由内燃机和电机组成的驱动单元，所述内燃机和电机的曲轴和转子彼此耦联。在此，内燃机和电机能够分别独立地或共同地提供用于驱动机动车辆的驱动力矩，电机能够启动内燃机并且电机能够在惯性滑行下进行能量回收利用。
发明内容
本发明的目的是，提出一种驱动单元，其具有通至后续要驱动的部件、例如混合动力传动系的要驱动的部件的扭振隔离的接口。本发明的目的尤其是改进内燃机与电机之间的连接。
所述目的通过根据本发明的驱动单元实现。在下文中描述了本发明的有利实施方式。
提出的驱动单元尤其设置用于混合动力传动系以提供驱动力矩。在此，内燃机和/或电机能够提供相应的驱动力矩，内燃机能够由电机启动，并且电机能够在具有混合动力传动系的机动车辆的惯性滑行模式下将机动车辆的动能回收为电能，所述电能存储在蓄电池或电池中。为此，例如能够使内燃机停止运转，并且可能通过自动阀等来消除或减小惯性滑动力矩。为了将驱动单元与其余混合动力传动系解耦，能够在驱动单元下游连接有离合器、例如构成为摩擦离合器的分离式离合器和/或起动离合器。
内燃机包括第一壳体和曲轴，电机包括第二壳体和转子，所述第二壳体牢固地容纳定子。两个壳体牢固地彼此连接，例如彼此拧紧以及以优选的方式彼此定心，使得曲轴、定子以及在遵守预设的气隙的情况下的转子至少在预设的公差内彼此同轴地设置。曲轴和转子直接或间接地彼此旋转配合地(drehschlüssig)连接。
为了在曲轴与转子、驱动单元的通至后续部件、例如混合动力传动系的动力传动系装置的扭振隔离的接口之间构成旋转配合的连接，以及为了提供内燃机和驱动单元彼此的简单接合过程，在曲轴上以定心的方式紧固有飞轮，并且抗扭地容纳有由电机和扭振减振器形成的结构单元的输入部件。飞轮借助于其惯性矩用于稳定受扭振影响的曲轴，而扭振减振器具有扭振减振作用。转子的惯性矩以及可能电机的主动控制还用于扭振隔离。扭振减振器能够设置在转子的径向内部。此外，转速自适应的扭振缓冲器、例如连接在扭振减振器的上游或下游和/或连接在转子的上游或下游的离心力摆能够与驱动单元相关联，并且可能在转子的径向内部或与其轴向相邻地设置。此外，湿式运行或干式运行的摩擦离合器能够连接在驱动单元的下游，并且可能在转子的轴向结构空间中设置在转子的径向内部或者与所述转子轴向间隔开地设置。扭振减振器在其减振器输入部件与其减振器输出部件之间具有在环周方向上有效的弹簧装置，所述弹簧装置包括至少一个减振器级，所述减震器级具有在环周上分布设置的长的、构成为弧形弹簧的螺旋压力弹簧和/或在环周上分布设置的短的螺旋压力弹簧。替选地，能够设有具有多个彼此嵌套的螺旋压力弹簧的弹簧组。
飞轮能够形成为由环形部件、环形盘部件或者由在环周上分布设置的环形部段构成的圆盘式飞轮，所述环形部段设置在薄的盘部件或环形盘部件的一侧或两侧处。
飞轮能够借助于在环周上分布地例如在预设的部分圆上设置的紧固螺栓紧固在曲轴上，其中结构单元的输入部件借助于中央螺栓紧固在飞轮上。例如，为此，飞轮能够具有轴向扩展的在中央凹部处定心的凸出部，所述凸出部具有内螺纹，其中输入部件在中央螺栓上定心并且在飞轮与中央螺栓之间轴向夹紧。能够借助于形状配合或者借助于飞轮与输入部件之间的夹紧效果设置有所施加的扭矩的传递。替选地，飞轮和输入部件能够借助于中央螺栓紧固在曲轴上。在此，转子的内环周能够在飞轮处定心。
替选地，飞轮能够借助于中央螺栓紧固在曲轴上，并且输入部件例如借助于设置在部分圆上的紧固螺栓紧固在飞轮上并且相对于飞轮定心。
结构单元的输入部件、尤其在曲轴或在飞轮上紧固的且与转子设置的连接部件能够轴向弹性地构成。例如，能够在曲轴上借助于中央螺栓或借助于设置在部分圆上的紧固螺栓紧固有携动盘，由轴向弹性的板部件、多个彼此贴靠安置的弹簧片或在环周上分布的板簧或板簧组形成的所谓的柔性板与所述携动盘连接，或者贴靠在所述携动盘处，并且径向在外部紧固在电机的转子上。携动盘例如能够是独立构成的飞轮的一部分。替选地，轴向弹性的输入部件能够与曲轴直接地或者借助于携动盘连接，其中飞轮紧固在输入部件的轴向弹性的区域的径向外部，例如径向在外部例如环形地紧固在柔性板上。所述飞轮例如能够轴向相对于转子、例如在径向上与电机的转子和/或定子相交地设置。

具体实施方式
图1示出围绕旋转轴线d设置的驱动单元100的上部分，所述驱动单元具有内燃机101、飞轮102，以及由电机104和扭振减振器105形成的结构单元103。
飞轮102构成为圆盘式飞轮，并且借助于在预设的部分圆上在环周上分布设置的紧固螺栓106与内燃机101的曲轴107拧紧。飞轮102具有轴向扩展的凸出部109，所述凸出部接合在曲轴107的中央开口108中，并且使飞轮102相对于曲轴107定心。
结构单元103的壳体110在飞轮102的径向外部借助于未示出的螺栓与内燃机的壳体111连接并在所述内燃机的壳体处定心。结构单元103的输入部件112包括与电机104的转子117径向在外部连接的刚性盘部件114。盘部件114径向在内部借助于中央螺栓115相对于飞轮102轴向预紧，并且可能具有相对于所述飞轮的形状配合。中央螺栓115与飞轮102的内螺纹116拧紧。
为了遵守在转子117和与壳体110连接的定子118之间的预设的气隙113，盘部件114借助于中央螺栓115相对于飞轮102定心，从而通过飞轮102的经由曲轴107至壳体111的公差链相对于定子118定心。
输入部件112——如在此所示——在盘部件114处抗扭地容纳在此连接在电机104的下游的扭振减振器105的减振器输入部件119。减振器输出部件120与输出毂121连接。在环周方向上在减振器输入部件119与减振器输出部件120之间并且在环周方向上以由其加载的方式设置有弹簧装置122。弹簧装置122包括在环周上分布设置的螺旋压力弹簧123、例如在其使用直径上预弯曲的弧形弹簧。
在驱动单元100的示出的实施例中，内燃机101不相对于曲轴107密封。相反，结构单元103一方面借助于在壳体部段125在所述壳体部段的内环周处与盘部件114的凸肩126之间的密封件127向外密封，并且另一方面借助于在法兰部件128的内环周与输出毂121之间设置的密封件129向外密封，所述壳体部段轴向设置在飞轮102与盘部件114之间。借助于轴向固定轴承、例如深沟球轴承可旋转地实现输出毂121在壳体110处的支承机构130。
通过壳体110、111在飞轮102的径向外部的连接并且通过将中央螺栓115与预安装在曲轴107处的飞轮102拧紧来实现结构单元103在壳体111处的安装。通过在输出毂121与轴或轴端的互补装齿的部件之间的啮合来实现驱动单元100与混合动力传动系的后续部件的连接。
图2在示意性截面图中示出围绕旋转轴线d设置的、与图1的驱动单元100类似的驱动单元200的上部分。与驱动单元100不同，驱动单元200具有结构单元203的轴向柔性构成的输入部件212，例如以用于补偿未详细示出的内燃机的曲轴207的轴向振动、摆动振动和/或屏振动(Schirmschwingung)。为此，借助于携动盘231实现电机204的转子217的连接，所述携动盘在其内环周处借助于定心凸缘232以定心的方式容纳在飞轮202处，并且借助于与飞轮202拧紧的中央螺栓215轴向相对于飞轮202预紧，并且可能与所述飞轮旋转配合地连接。飞轮202借助于紧固螺栓206与曲轴207拧紧。
在携动盘231处，借助于紧固螺栓234，盘部件214与轴向柔性的连接部件233牢固地被容纳，并且径向在外部与转子217连接。以这种方式，转子217轴向弹性地且抗扭地与曲轴207耦联。借助于径向向内延伸的法兰部件236实现转子217相对于电机204的壳体210的支承机构230。
扭振减振器205的减振器输入部件219与盘部件214的轴向固定区域连接。在此，在减振器输入部件219、减振器输出部件220和弹簧装置222之间补偿输入到扭振减振器205中的轴向振动。
图3在示意性截面图中示出围绕旋转轴线d设置的驱动单元300的上部分。与图2的驱动单元200不同，驱动单元300的飞轮302环形地构成，并且连接在结构单元303的轴向柔性构成的输入部件312的下游，并且设置在电机304或结构单元303的壳体310内。为此，携动盘331借助于与曲轴307拧紧的中央螺栓315可能形状配合地轴向预紧地紧固在未详细示出的内燃机的曲轴307上。在携动盘331上，借助于紧固螺栓334，盘部件314与轴向弹性的连接部件333连接。在连接部件333的径向外部，环形飞轮302与电机304的转子317以及盘部件314连接，例如借助于铆钉335铆接。
扭振减振器305的减振器输入部件319在背离转子317与盘部件314的连接的一侧处与和转子317连接的法兰部件336连接。法兰部件336从而转子317借助于支承机构330、例如如在此所示借助于轴向固定轴承在壳体310处可旋转地支承，使得在连接部件333内实现可能施加到曲轴307上的轴向振动的减振。
图4在示意性截面图中示出围绕旋转轴线d设置的驱动单元400的上部分。与图3的驱动单元300不同，飞轮402设置在壳体410外，并且与借助于中心螺栓415在曲轴407上紧固的携动盘431直接地连接，例如如在此所示焊接。转子417在携动盘431处的连接借助于输入部件412来实现，所述输入部件包括具有轴向弹性的连接部件433的刚性的盘部件414。减振器输入部件419对应于图2的减振器输入部件219与盘部件414的刚性部件连接。
图5在示意性截面图中示出围绕旋转轴线d设置的驱动单元500的上部分。与图3的具有结构单元303的向外密封的壳体310的驱动单元300不同，内燃机501在曲轴507与壳体511之间借助于密封件524密封，使得能够取消如在图3中所示的壳体510相对于携动盘331的密封，并且仅在壳体510与轴537之间设有密封件529。
图6示出相对于图1的驱动单元100略微改变的驱动单元600，所述驱动单元具有对应于图5的驱动单元500相应改变的密封构思，在省略壳体610与转子617之间密封件的情况下，所述驱动单元在内燃机601的壳体611与曲轴607之间具有密封件624，使得能够取消图1的壳体部段125。
图7示出相对于图4的驱动单元400略微改变的驱动单元700，所述驱动单元具有对应于图5的驱动单元500改变的密封构思，在省略壳体710与携动盘731之间的密封件的情况下，所述驱动单元在内燃机701的壳体711与曲轴707之间具有密封件724，使得也能够取消用于相对于携动盘731密封壳体710的壳体部段，并且飞轮702能够至少径向在外部轴向朝向结构单元703扩展。
图8至图13在示意性截面图中分别示出围绕旋转轴线d设置的驱动单元800、900、1000、1100、1200、1300的上部分，其中与图1至图7的驱动单元100、200、300、400、500、600、700相反，扭振减振器805、905、1005、1105、1205、1305连接在电机804、904、1004、1104、1204、1304的上游。这意味着，减振器输入部件819、919、1019、1119、1219、1319形成结构单元803、903、1003、1103、1203、1303的输入部件812、912、1012、1112、1212、1312。
驱动单元800、900、1000、1100、1200、1300至少在下文中描述的特征中彼此不同。
图8的驱动单元800具有飞轮802，所述飞轮借助于中央螺栓815与曲轴807连接。减振器输入部件819与飞轮802牢固地连接、例如焊接或铆接。
减振器输出部件820与法兰部件836牢固地连接，例如焊接或铆接。法兰部件836径向在外部与转子817连接、例如焊接，并且径向在内部与输出毂821连接、例如焊接。
与图8的驱动单元800不同，图9的驱动单元900具有携动盘931，其借助于中央螺栓915与曲轴连接。飞轮902与携动盘931焊接，并且减振器输入部件919借助于紧固螺栓934与携动盘931拧紧。
转子917、与其连接的法兰部件936以及输出毂921借助于弹簧元件938相对于减振器输入部件919轴向预紧，使得密封件929在输出毂921与轴937的环形边缘939之间轴向预紧。
基于图1的驱动单元100，图10的驱动单元1000具有借助于紧固螺栓1006直接紧固在曲轴1007上的飞轮1002，在所述飞轮处，由减振器输入部件1019形成的输入部件1012借助于中央螺栓1015容纳。
图11的驱动单元1100与图9的驱动单元900类似，不同之处在于密封构思。对应于图1和图6的驱动单元100、600之间的密封构思的不同，驱动单元900在曲轴907与内燃机的未示出的壳体之间不具有密封件，而驱动单元1100在曲轴1107与壳体1111之间具有密封件1124，并且能够取消在携动盘1131与壳体1110之间的密封。
以相同的方式，与图10和图8的在其他方面类似的驱动单元1000、800相反，图12和图13的驱动单元1200、1300分别在曲轴1207、1307与壳体1211、1311之间具有密封件1224、1324，使得能够取消壳体1210、1310与减振器输入部件1219或曲轴1307之间的相应密封件以及壳体1210、1310的径向向内扩展的壳体部段。
