用于混合动力车辆的驱动系
技术领域
本发明涉及一种驱动系，借助该驱动系能够驱动混合动力车辆。
背景技术
由WO2015/110 108 A1已知一种用于混合动力车辆的驱动系，其中，内燃机的曲轴能够通过第一离合器与变速器输入轴进行离合，电机的转子也能够通过第二离合器耦合到该变速器输入轴上。沿轴向方向在电机旁，能够无级调节的CVT变速器通过齿轮级衔接到该变速器输入轴上，以便转换变速器输入轴的转矩并且将其传导到差速器传动装置上。附加地，沿轴向方向在电机旁还设置有第三离合器，直接传动级能够通过该第三离合器耦合到所述变速器输入轴上，以便将转矩未转换地绕过CVT变速器传递到差速器传动装置上。
存在持续的需求使驱动系适配狭窄的安装空间。
发明内容
本发明的任务是给出能够实现适合于狭窄安装空间的驱动系的措施。
根据本发明，该任务的解决方案通过本发明的驱动系来实现。在从属权利要求和下面的说明中给出本发明的优选构型，所述优选构型能够分别单独地或组合地示出本发明的一个方面。
根据本发明，设置用于混合动力车辆的驱动系，其具有：用于导入尤其在内燃机中产生的转矩的驱动轴；能够通过第一离合器与驱动轴耦合的变速器输入轴；与该变速器输入轴耦合的能够无级调节的变换器，用于将转矩转换和传递到从动轴上；用于导入电式地产生的转矩的电机，其中，所述电机具有能够与定子共同作用的转子，并且该转子能够通过第二离合器与变速器输入轴耦合；和能够通过第三离合器与电机的转子耦合的直接传动级，用于将在电机中产生的转矩绕过变换器传递到从动轴上，其中，第一离合器、第二离合器和第三离合器相对于转子径向内部地布置。
电机能够在电动机运行中将电能作为电式地产生的转矩导入到驱动系中，从而尤其能够纯电地驱动机动车。此外，电机能够在发电机运行中将转矩从驱动系分出并且产生电能，该电能尤其储存在机动车电池中，优选地用于纯电地驱动机动车的牵引电池中，并且能够在晚一些的时刻再次调用。电机尤其能够具有由电磁体组成的定子，该定子能够与优选由永磁体组成的转子共同作用，以便交换功率。原则上，在能够电驱动的机动车中希望电机的高功率。高的电功率能够通过转子和定子具有尽可能大的直径和尽可能大的轴向延伸量的方式实现，因为由此能够设置特别多共同作用的永磁体和/或电磁体。然而，电机的尺寸被机动车中可提供的安装空间严重地限制。
在本发明中利用以下认识：尤其在能够电驱动的机动车中构造在电机径向内部的安装空间能够足够大，以便在该安装空间中设置第一离合器、第二离合器和第三离合器。由此能够节省沿轴向方向在电机旁的安装空间，否则在该安装空间中例如将布置有第三离合器。这使得能够提高电机的轴向延伸量进而提高其功率和/或能够减小驱动系的轴向延伸量。第一离合器、第二离合器和第三离合器能够沿轴向方向相继设置。第一离合器、第二离合器和第三离合器尤其设置在共同的半径区域内，使得沿径向方向观察，这些离合器能够至少部分地覆盖。由此不需要第一离合器、第二离合器和/或第三离合器通过齿轮级相对于变速器输入轴径向偏移地与该变速器输入轴耦合。由此能够节省径向安装空间。通过相对于电机径向内部地设置的离合器能够沿轴向和/或径向方向节省安装空间，使得能够实现适合于狭窄安装空间的驱动系。
驱动轴例如能够构型为曲轴并且是内燃机的一部分。优选地，所述驱动轴具有扭振减振器，例如双质量飞轮，使得该驱动轴能够借助在输出侧设置用于扭振减振器的毂与第一离合器共同作用。第一离合器例如构型为摩擦离合器、尤其片式离合器。该第一离合器能够作为分离离合器将驱动轴与变速器输入轴分离和/或接合到变速器输入轴上。变换器能够与变速器输入轴永久耦合。为此，变速器输入轴能够同时构型为用于将转矩导入到变换器中的变换器驱动轴并且伸入到变换器中。变速器输入轴也能够通过抗扭的(例如构造为插接齿部的)连接与单独的同轴布置的变换器驱动轴连接。此外，变换器能够相对于变速器输入轴径向偏移地与该变速器输入轴(例如通过齿轮级)耦合。变换器尤其构型为CVT变速器(“CVT”：continuous variable transmission)。变换器例如具有通过牵引器件相互耦合的锥盘对，其中，各锥盘对的锥盘的间距能够被改变，以便使传动比无级地变化。借助直接传动级，功率流能够绕过变换器被引导。电机的转速和转矩能够通过合适的调节在电机的功率输入时已经被调整，这在纯电驱动的情况下是合适的。在这种情况下，能够取消转速和转矩借助变换器的转换，使得能够避免在变换器中的由摩擦引起的功率损失。直接传动级能够在第三离合器闭合时例如通过中间连接的齿轮级和/或中间连接的中间轴将变速器输入轴与差速器传动装置耦合。该差速器传动装置具有至少一个从动轴，该从动轴通向机动车的驱动轮，以便机动车在地面上向前运动。优选地，仅设置电机用于机动车倒车，该电机能够容易地沿不同方向旋转。能够在驱动系中省去机械的旋转方向换向装置，由此能够节省为此所需的安装空间。变速器输入轴尤其相对于电机同轴地延伸。该变速器输入轴能够与泵耦合，借助该泵能够建立尤其用于运行变换器和/或用于切换所述第一、第二和/或第三离合器的液压压力。变速器输入轴优选具有输送通道，液压油或其它介质能够穿过所述输送通道被输送到相应的液压消耗装置。
尤其第一离合器、第二离合器和第三离合器沿径向方向观察在打开和/或闭合状态中至少部分地、优选完全地被转子覆盖。第一离合器、第二离合器和第三离合器能够插入到电机中。电机以及第一离合器、第二离合器和第三离合器能够布置在共同的轴向安装空间区域中，使得能够最小化驱动系的轴向延伸量。例如，驱动轴和/或与该驱动轴耦合的毂能够伸入到电机中，使得第一离合器能够完全设置在电机内。
优选地，第二离合器和/或第三离合器构型为尤其可液压操纵的楔形离合器。该楔形离合器作为第一传递元件能够具有楔形盘，该楔形盘具有多个沿周向方向在共同半径上分布的沿轴向或径向方向指向的楔形斜坡，所述楔形盘能够通过选择盘与作为第二传递元件的转动盘耦合。该选择盘具有对应于楔形斜坡的楔形配对斜坡，该配对斜坡与斜坡构成斜坡系统。根据选择盘相对于楔形盘的相对旋转能够提高斜坡系统的延伸量，使得选择盘能够相对于楔形盘轴向移位。选择盘由此能够在转动盘上被摩擦锁合地楔紧和/或与例如构型为环的转动盘(尤其以插接齿部的类型)形状锁合地耦合，由此能够闭合楔形离合器并且能够传递转矩。在转动盘相对旋转到相反方向时，能够减小斜坡系统的延伸量，由此能够打开楔形离合器并且能够中断转矩传递。楔形离合器原则上能够类似于没有中间连接滚动体的情况下的单侧作用的自由轮地构型。适合的楔形离合器作为“Schaeffler WedgeClutch”已知。楔形离合器尤其能够如在DE 10 2012 218 282 A1和/或DE 10 2013 220223 A1中所说明地构造和扩展，借此参考其内容作为本发明的一部分。楔形离合器具有特别小的轴向延伸量，使得第二离合器和/或第三离合器能够容易地相对于电机转子径向内部地插入到电机中。优选地，第二离合器和/或第三离合器能够被液压操纵，从而不需要设置用于操纵第二离合器和/或第三离合器的电路和电磁体。替代地，能够使用建立的液压压力用于运行变换器，尤其用于液压地改变传动比关系，以便液压地操纵第二离合器和/或第三离合器。
特别优选地，转子具有从该转子径向向内突出的传递盘，用于导入在电机中产生的转矩，其中，所述传递盘具有尤其构型为楔形盘的第二传递元件，用于在构型为楔形离合器的第二离合器中传递转矩，和/或具有尤其构型为楔形盘的第三传递元件，用于在构型为楔形离合器的第三离合器中传递转矩，其中，尤其第一楔形盘和第二楔形盘设置在传递盘的不同轴向侧上。转子尤其能够通过传递盘径向和/或轴向地支撑和支承在变速器输入轴上，由此能够避免转子的倾翻。为此设置的传递盘在此能够构成第二离合器和/或第三离合器的部件或者与第二离合器和/或第三离合器的部件抗扭地固定。第二离合器和/或第三离合器的传递元件例如能够与传递盘铆接和/或焊接。尤其，不但第二离合器而且第三离合器的传递元件固定在传递盘上，从而产生基本上对称的结构。与传递盘固定的传递元件尤其能够相同或镜像对称地构型。
在另一实施方式中，例如通过插接齿部与转子抗扭地耦合的传递盘能够沿轴向方向可运动地实施，使得为了闭合第二离合器或第三离合器仅需要传递盘被轴向地移位。第二离合器和第三离合器的其余部分尤其沿轴向方向不可运动。由此能够保证：或者仅第二离合器或者仅第三离合器能够将电机的转矩或者传递到变换器上或者绕过变换器地传递。由此排除直接传动级与变换器的冲突。在传递盘的中间位态中，不但能够打开第二离合器而且能够打开第三离合器，使得能够根据第一离合器的切换状态例如摆脱机动车变速器拖曳力矩或借助内燃机实现纯机械的驱动。
尤其设置遮盖电机的电动机壳体，其中，该电动机壳体具有用于给第三离合器供给液压油的供油通道，其中，液压油尤其通过第三离合器的可轴向移位的操纵元件引导。第三离合器能够沿轴向方向设置在电机的边缘处，使得该第三离合器能够特别近地设置在遮盖电机的电动机壳体上。第三离合器尤其具有可液压操纵的操纵元件，该操纵元件例如在环形的操纵缸中被导向。操纵元件能够被操纵缸中建立的液压压力轴向移位。该操纵元件能够尤其具有油通道，该油通道能够在任何轴向相对位置与电动机壳体的供油通道联通。同时，操纵元件的油通道能够与操纵缸内部空间联通，使得可轴向移位的操纵元件能够将液压油从电动机壳体的固定的供油通道传送到操纵缸内部空间。操纵元件的油通道为此例如能够经由相应于该操纵元件的轴向移位路径的轴向路段径向向外地打开，使得电动机壳体的供油通道能够独立于操纵元件的轴向相对位置与操纵元件的油通道联通。电动机壳体的固定的供油通道由此能够容易地通过可轴向移位的操纵元件与旋转的环形操纵缸联通，以便能够将液压油传送到第三离合器和操纵第三离合器。
优选地，所述变换器具有在驱动侧的驱动锥盘对和通过牵引器件与该驱动锥盘对耦合的从动锥盘对，其中，驱动锥盘对具有能够借助驱动轴向保险元件受限地轴向移位的驱动调整盘，并且从动锥盘对具有能够借助从动轴向保险元件受限地轴向移位的从动调整盘，其中，沿径向方向观察，用于在驱动侧支承变换器的驱动轴承至少部分地覆盖驱动轴向保险元件，和/或沿径向方向观察，用于在从动侧支承变换器的从动轴承至少部分地覆盖从动轴向保险元件。相应的轴向保险元件能够限界相应锥盘对的锥盘的最大允许间距。轴向保险元件为此例如能够构型为安装到槽中的保险环。相应的轴承能够相对于轴向保险元件布置在径向外部，使得能够节省轴向的安装空间。优选地，轴向保险元件被所配属的轴承在径向方向上完全覆盖。相应轴承的内环能够具有部分地沿轴向方向引入到内环中的凹进部，所配属的轴向保险元件能够安装到所述凹进部中。剩余内环能够贴靠、尤其压抵在与驱动锥盘对耦合的变换器驱动轴上或者与从动锥盘对耦合的变换器从动轴上。相应的轴承能够借助内环的一部分轴向地固定在所配属的轴向保险元件和所配属的可轴向移位的调整盘之间。
变换器的锥盘尤其具有7°至11°、优选9°±0.5°的锥角。优选地，从动锥盘对和/或驱动锥盘对不配备有离心油罩，从而能够节省更多安装空间。尤其，仅驱动锥盘对或仅从动锥盘对配备有用于阻拦由离心力引起的甩出的液压油的离心油罩，而优选地，另一锥盘对仅配备有回位弹簧并且没有液压操纵装置。回位弹簧的弹簧力能够使所配属的锥盘对运动到相应于该锥盘的最大靠近或最大间距位置的限定的初始位置中，而在另一锥盘对中能够建立的液压压力能够使锥盘从初始位置运动出来。
特别优选地设置遮盖变换器的变换器壳体，其中，该变换器壳体和/或遮盖电机的电动机壳体至少部分地覆盖直接传动级，其中，所述直接传动级固定在变换器壳体上。直接传动级例如能够具有支承在轴上的齿轮用于形成齿轮级，其中，所述轴与变换器壳体例如通过拧接来固定。这能够实现将直接传动级与变换器预装配并且将具有电机的结构单元作为整体与变换器固定。在此，例如变速器输入轴能够与变换器预装配，并且第一离合器、第二离合器和第三离合器在装配时被插装到变速器输入轴上，尤其用于构成插接连接，例如插接齿部。
变换器尤其具有在驱动侧与变速器输入轴耦合的变换器驱动轴，其中，变换器驱动轴基本上与变速器输入轴同轴地布置，并且第一离合器和/或第二离合器在输出侧尤其通过插接连接与变换器驱动轴抗扭地耦合，或者其中，变换器驱动轴通过中间齿轮对相对于变速器输入轴侧向偏移地布置。在变换器驱动轴相对于变速器输入轴的同轴布置中，尤其能够使变换器驱动轴和变速器输入轴一体地构型。由此能够减少构件数量。在变换器驱动轴相对于变速器输入轴侧向偏移的布置中，能够使用不能容易倾翻的和/或弯曲的短轴用于变换器驱动轴和变速器输入轴。
优选地，直接传动级具有与第三离合器啮合的中间轮，其中，所述中间轮与支承在从动侧的变换器从动轴啮合，其中，变换器从动轮尤其通过差速器传动装置与从动轴耦合。由此能够避免用于直接传动级的中间轴，从而能够实现用于驱动系的特别节省安装空间的结构。尤其能够节省径向的安装空间。替代地，能够在直接传动级中使用变换器从动轮用于跨接在变速器输入轴与差速器传动装置或从动轴之间的距离。尤其设置：变换器从动轮能够通过变换器离合器与变换器的变换器从动轴抗扭地耦合。如果驱动系的功率流要经由变换器流过，则能够打开第三离合器并且闭合变换器离合器。如果传动系的功率流要绕过变换器经由直接传动级流动，则能够闭合第三离合器并且打开变换器离合器。
特别优选地，直接传动级具有与第三离合器啮合的中间轴，其中，该中间轴尤其通过差速器传动装置与从动轴耦合。通过中间轴能够在经由直接传动级的功率流的情况下使中间连接的齿轮对最小化。由此能够避免例如由于齿轮对之间的摩擦产生的不必要的功率损失。在变速器输入轴和差速器传动装置之间，在直接传动级中优选仅设置正好两个齿轮对，能够通过与中间轴的啮合构成所述两个齿轮对。
附图说明
下面参照附图根据优选的实施例示例性地阐述本发明，其中，下面所示的特征不但能够分别单独地而且能够以组合方式示出本发明的一个方面。其示出了：
图1：驱动系的第一实施方式的示意性原理示图；
图2：图1的驱动系的示意性截面视图；
图3：驱动系的第二实施方式的示意性原理示图；
图4：驱动系的第四实施方式的示意性原理示图。
具体实施方式
驱动系10在图1中以展开的侧视图并且以俯视图示出，以及在图2中更详细地示出，该驱动系具有驱动轴12，其中涉及能够通过构型为双质量飞轮的扭振减振器14与内燃机的曲轴耦合的毂。驱动轴12能够通过构型为片式离合器的第一离合器16与变速器输入轴18耦合。驱动系10附加地具有电机20，该电机具有带有电磁体的定子22和带有能够与该定子22共同作用的永磁体的转子24。传递盘26与该转子24抗扭地连接，该传递盘支撑和支承在变速器输入轴18上。借助构型为能够液压操纵的楔形离合器的第二离合器28，传递盘26进而电机20的转子24能够与变速器输入轴18抗扭地耦合，以便将电机20中以电动机运行方式产生的电功率导入到驱动系10中或将从该驱动系获得的机械功率在以发电机运行方式运行的电机20中转换为能够存储的电能。
变速器输入轴18的转速和转矩能够在构型为CVT带变速器的变换器30中被转换。为此，变换器驱动轴32与变速器输入轴18耦合。在示出的实施方式中，变换器驱动轴32和变速器输入轴18能够合并为一体的共同轴。变换器驱动轴32驱动在驱动侧的驱动锥盘对34，该驱动锥盘对通过构型为带传动装置的牵引器件36与在从动侧的从动锥盘对38耦合。变换器30的传动比能够根据驱动锥盘对34和从动锥盘对38的位态而无级地调整。从动锥盘对38驱动变换器从动轴40，该变换器从动轴与变速器输入轴18相比能够具有转换的转速和转换的转矩。在变换器从动轴40上支承有变换器从动轮42。该变换器从动轮42能够借助变换器离合器44与变换器从动轴40抗扭地耦合。变换器从动轮42能够通过连接轮46与差速器传动装置48连接，尤其用于逆转旋转方向和/或增加传动比，该差速器传动装置又具有通向驱动轮的从动轴50。
借助直接传动级52，来自变速器输入轴18的功率流能够绕过变换器30导向差速器传动装置48和从动轴50。为此，转子24的传递盘26能够借助构型为能够液压操纵的楔形离合器的第三离合器54与直接传动级52耦合。在所示的实施例中，直接传动级52通过中间轮56与变换器从动轮42耦合，从而仅需要最小的安装空间用于实施直接传动级52。
如在图2中所示，中间轮56支承在与变换器30拧紧的轴58上，使得直接传动级52能够与变换器30一起被预装配。由此，第一离合器16、第二离合器28和第三离合器54尤其能够通过构型为插接齿部的插接连接插装到驱动轴18上并且与电机20和遮盖电机20的电动机壳体60一起与变换器30连接。在此，电动机壳体60能够与遮盖变换器30的变换器壳体62固定。在电动机壳体60中能够设置有供油通道64，通过该供油通道，设置用于操纵第三离合器54的液压油能够被供应到第三离合器54。为了供给在驱动系10中的另外的液压消耗装置，例如为了操纵第一离合器16和/或为了操纵第二离合器28和/或为了操纵变换器30的驱动锥盘对34和/或为了操纵变换器30的从动锥盘对38，变速器输入轴18和变换器驱动轴32能够中空地构型和/或配备有相应的供给通道。优选地，变速器输入轴18和/或变换器驱动轴32能够与泵66耦合，该泵能够建立为此所需的液压压力。泵66尤其设置在变换器30的远离电机20的一侧上。
为了改变变换器30的传动比，驱动锥盘对34的一个锥盘构型为能够液压地轴向移位的驱动调整盘67。根据驱动调整盘67的轴向相对位置，牵引器件36移位到其它的半径上。同时，从动锥盘对38的一个锥盘构型为能够轴向移位的从动调整盘68，该从动调整盘在驱动调整盘67的相对位置改变时本身改变其相对位置，以便牵引带36保持张紧。在此能够设置：从动调整盘68对应于驱动调整盘67液压地轴向移位。附加地或替代地，能够设置有作用在从动调整盘68上的回位弹簧70，在驱动调整盘67上建立液压压力必须抵抗其弹簧力。
变换器驱动轴32能够通过驱动轴承72支承在变换器壳体62上，而变换器从动轴40能够通过从动轴承74支承在变换器壳体62上。驱动锥盘对34的最宽位态能够通过构型为保险环的驱动轴向保险元件76限界，而从动锥盘对38的最宽位态能够通过构型为保险环的从动轴向保险元件78限界。驱动轴向保险元件76能够被安装到变换器驱动轴32的槽中，而从动轴向保险元件78能够被安装到变换器从动轴40的槽中。在所示的实施例中，驱动轴向保险元件76相对于驱动轴承72径向内部地设置，并且为此安装到驱动轴承72的相应凹进部中。从动轴向保险元件78相对于从动轴承74设置在径向内部，并且为此安装到从动轴承74的相应凹进部中。由此减小变换器30的进而驱动系10的轴向安装空间需求。同样，通过第一离合器16、第二离合器28和第三离合器54至少部分地、优选完全地布置在电机20、尤其转子24的径向内部的方式来减小驱动系10的轴向安装空间需求。沿径向方向观察，转子24能够至少部分地、优选完全覆盖第一离合器16、第二离合器28和第三离合器54。
与在图1和2中所示的驱动系10的实施方式相比，在图3中所示的驱动系10的实施方式中，与变换器从动轮42啮合的中间轮56被与差速器传动装置48啮合的中间轴80代替。由此，在绕过变换器30引导功率流的情况下实现特别少的齿轮对。
与在图3中所示的驱动系10的实施方式相比，在图4中所示的驱动系10的实施方式中，变换器驱动轴32不是与变速器输入轴18同轴地布置，而是侧向偏移地布置。在此，变换器驱动轴32通过中间齿轮对82耦接到变速器输入轴18上，由此能够省去连接轮46。中间齿轮对82能够承担连接轮46的功能并且由此代替连接轮46。此外，在所示的实施例中设置区域切换单元84，该区域切换单元通过行星变速器将变换器从动轴40与同轴的连接轴86耦合。区域切换单元84能够具有制动器，该制动器例如能够选择性地保持行星变速器的空心轮固定，以便改变变换器从动轴40和连接轴86之间的传动比和/或旋转方向。在此，行星变速器的太阳轮能够与变换器从动轴40连接，而行星变速器的行星架接片能够通过变换器离合器44与连接轴86连接。连接轴86以能相对扭转的方式支承在变换器从动轴40上。此外，变换器从动轮42能够与连接轴86抗扭地连接。
