Description

具有变速器输入轴、变速器输出轴和三个行星齿轮组的变速 器装置
技术领域
本发明涉及一种根据在权利要求1的前序部分中详细定义类型的变速器装置,其具有变速器输入轴、变速器输出轴和三个齿轮组。
背景技术
由DE102005014592 A1已知一种具有变速器输入轴和变速器输出轴以及四个行星齿轮组的、构成为8挡变速器的变速器装置。这四个行星齿轮组总共具有六个所谓的连接轴和为形成八个传动比(在这些传动比期间变速器输入轴和变速器输出轴以相同的或不同的旋转方向旋转并且形成所谓的用于前进行驶的传动比)而至少部分在行星齿轮组轴(即齿圈、太阳轮和行星架)的区域内彼此作用连接、经由五个切换元件至少部分地可彼此连接并且在行星齿轮组轴的区域内与连接轴耦合。
变速器装置的这种已知的变速器构思不利地仅能以高的结构耗费与各种不同的要求相适配,这然而与减小制造费用的模块化的积木原理背道而驰。
此外在已知的变速器装置的区域中在不利的状态过程期间出现高的构件负载和损害效率的损失功率。
发明内容
因此,本发明的目的在于,提供一种变速器装置,其特征在于在运行中较小的构件负载和在运行中低的损失功率并且能够以小的结构耗费与各种不同的要求相适配。
根据本发明,该任务通过具有权利要求1的特征的变速器装置解决。
根据本发明的变速器装置包括变速器输入轴、变速器输出轴和三个行星齿轮组,这些行星齿轮组具有总共七个连接轴。这些行星齿轮组为了形成至少六个传动比(在这些传动比期间变速器输入轴和变速器输出轴以相同或不同的旋转方向旋转并且在变速器装置应用在机动车中时优选形成所谓的用于前进行驶的传动比)而至少部分在行星齿轮组轴(即齿圈、太阳轮和行星架)的区域内彼此作用连接、经由切换元件至少部分可彼此连接并且在行星齿轮组轴的区域内与连接轴耦合。
根据本发明的变速器装置此外具有接下来阐述的结构,以便将变速器装置的构件仅仅在小的范围内加载并且同时在运行中产生低的损失功率,最后提到的优点借助于良好的啮合效率达到。
为此,行星齿轮组的第一连接轴与第一行星齿轮组的第一行星齿轮组轴和与固定在壳体上的构件不可相对旋转地连接,而第二连接轴与变速器输入轴和与第一行星齿轮组的第二行星齿轮组轴连接。附加地,第三连接轴与变速器输出轴和第三行星齿轮组的第二行星齿轮组轴连接。此外,第四连接轴与第一行星齿轮组的第三行星齿轮组轴连接并且经由其中一个切换元件与第七连接轴可连接,而第五连接轴与第二行星齿轮组的第三行星齿轮组轴和与第三行星齿轮组的第一行星齿轮组轴连接并且经由其中一个切换元件与固定在壳体上的构件可连接。此外第六连接轴与第三行星齿轮组的第三行星齿轮组轴连接并且与第二行星齿轮组的第二行星齿轮组轴连接并且经由其中一个切换元件与变速器输入轴可连接,而第七连接轴与第二行星齿轮组的第一行星齿轮组轴连接并且经由其中一个切换元件与固定在壳体上的构件可连接并且经由另外一个切换元件与变速器输入轴可连接。
根据本发明的变速器的变速器结构的特征在于结构上简单的构造,具有仅仅三个行星齿轮组,其此外可以实现减小制造费用的模块化构造方式。从而变速器装置借助于仅仅一个另外的切换元件、优选摩擦锁合或形锁合构成的制动器利用结构上较小的耗费这样可扩展,使得在变速器装置的区域中可提供两个另外的传动比,在所述两个另外的传动比期间变速器输入轴和变速器输出轴以不同或相同的旋转方向旋转并且在变速器装置应用在车辆的区域中时形成所谓的用于倒车的传动比。此外以结构上简单的方式存在这样的可能性,即根据本发明的变速器装置构成为混合变速器,其中为此所需要的电机仅仅需连接在行星齿轮组的其中一个连接轴的区域中。
在根据本发明的变速器装置的一个结构上简单扩展的实施方式中,第六连接轴经由一个另外的切换元件与固定在壳体上的构件可连接,以便可以形成两个用于倒车的传动比。
在机动车中使用根据本发明的变速器装置时,变速器输入轴与驱动机组的一个轴连接或经由离合器与之可连接,因此驱动机组的机械功率可以被输送给变速器输入轴。驱动机组可以不仅构成为内燃机,而且也可以构成为电机,或构成为为它们的组合。变速器输出轴用作用于将机械功率传递给机动车驱动车轮的接口。
轴、行星齿轮组轴和连接轴接下来不是仅仅理解成例如圆柱形的、可旋转地支承的用于传动转矩的机械元件,而是也可以理解成通常的将各单个构件或元件彼此连接的连接元件,特别是将多个元件彼此不可相对旋转地连接的连接元件。
行星齿轮组包括太阳轮、行星架和齿圈。在行星架上可旋转地支承行星齿轮,其与太阳轮的齿部和/或与齿圈的齿部啮合。接下来负传动比行星齿轮组描述这样的行星齿轮组,其包括行星架(行星齿轮可旋转地支承在该行星架上)、太阳轮和齿圈,至少其中一个行星齿轮的齿部不仅与太阳轮的齿部、而且与齿圈的齿部啮合,由此当太阳轮在行星架固定时旋转时,齿圈和太阳轮在相反的旋转方向上旋转。
不仅行星齿轮组的太阳轮而且齿圈也可以划分成多个分段。例如可以考虑的是,行星齿轮与两个不彼此连接的太阳轮啮合。转速比当然在太阳轮的两个分段上是相同的,从而它们似乎彼此连接。
正传动比行星齿轮组与上述负传动比行星齿轮组的区别在于:正传动比行星齿轮组具有内部和外部的行星齿轮,其可旋转地支承在行星架上。内部的行星齿轮的齿部在此一方面与太阳轮的齿部并且另外一方面与外部行星齿轮的齿部啮合。外部行星齿轮的齿部此外与齿圈的齿部啮合。这导致在行星架固定时齿圈和太阳轮在相同的旋转方向上旋转。
固定传动比定义在行星架不旋转的情况下行星齿轮组的太阳轮和齿圈之间的转速比。因为在负传动比行星齿轮组的情况下在行星架不旋转的情况下在太阳轮和齿圈之间的旋转方向是反向的,所以在负传动比行星齿轮组的情况下固定传动比始终是负值。
通过切换元件根据操作状态允许在两个构件之间的相对运动或者在两个构件之间建立用于传递转矩的连接。相对运动例如理解成两个构件的旋转,其中第一构件的转速不同于第二构件的转速。此外也可以考虑仅仅其中一个构件的旋转,而另外的构件静止或在相反的方向上旋转。
当在两个元件之间存在固定的特别是不可相对旋转的连接时,两个元件特别是而后称为彼此连接的或彼此耦合的。这样的连接的或彼此耦合的元件以相同的转速旋转。本发明的各种不同的构件和元件可以在此经由一个轴或经由闭合的切换元件或连接元件彼此连接,然而也可以直接地例如借助于焊接、压接或其它的连接彼此连接。
当在两个元件之间存在可松开的不可相对旋转的连接,那么称为两个元件是可连接的。当该连接存在时,这两个元件以相同的转速旋转。
电机至少由一个不旋转的定子和一个可旋转地支承的转子构成并且在马达式运行中设置用于将电能转换成转速和转矩形式的机械能,以及在发电机式运行中将机械能转换成电流和电压形式的电能。
齿轮组平面在该关联中理解成一个平面,在该平面中设置一个或多个行星齿轮组的元件齿圈、行星架和太阳轮。各元件不是必须在此对称地沿着该平面设置。而是概念齿轮组平面应当理解成一个结构空间平面,一个或多个行星齿轮组在变速器中的位置以该结构空间平面为特征。
如果第四轴与电机连接,那么根据本发明的变速器装置构成为混合变速器,其中电机经由所谓的变速器内部的预传动比连接到变速器装置的力流上。这提供优点,即电机可以以较小的外部尺寸和便宜地设计。
附加地,经由电机,当与变速器输入轴耦合的驱动机、优选内燃机在分离离合器的区域内与变速器输入轴可脱离耦合时,车辆也可以在倒车方向上运行。
在一个另外的特征在于高的功能密度的本发明的变速器装置的实施方式中,第六连接轴经由另外的切换元件与固定在壳体上的构件可连接,而第四连接轴与电机连接。在该实施方式中根据本发明的变速器装置不仅构成为混合变速器,而且附加地除了六个用于前进行驶的传动比之外也可形成两个用于倒车的机械传动比。
如果行星齿轮组构成为负传动比行星齿轮组,那么太阳轮分别构成行星齿轮组的第一行星齿轮组轴,行星架分别构成行星齿轮组的第二行星齿轮组轴,并且齿圈分别构成行星齿轮组的第三行星齿轮组轴,以便能够提供具有低的变速器损失、高的啮合效率、良好的传动比序列以及小的构件负载的根据本发明的变速器装置。
与之不同,在行星齿轮组构成为正传动比行星齿轮组时,行星齿轮组的第一行星齿轮组轴分别是太阳轮,行星齿轮组的第二行星齿轮组轴分别是齿圈,并且行星齿轮组的第三行星齿轮组轴分别是行星架,以便可以以良好的啮合效率和由此得到的低的变速器损失在同时小的构件负载的情况下运行本发明的变速器装置和可以构成良好的传动比序列。
如果将第五连接轴与固定在壳体上的构件连接的切换元件和/或将第六连接轴与固定在壳体上的构件连接的切换元件构成为形锁合的切换元件,那么在本发明的变速器装置的区域中的损失功率与这些切换元件构成为摩擦锁合的切换元件相比可进一步减小。这由这样的事实引起,即在处于打开的运行状态中的摩擦锁合的切换元件的区域中出现非期望地高的拖拽损失,其损害整体效率。
如果变速器输入轴能够经由附加的切换元件在力流中在切换元件——经由这些切换元件变速器输入轴能够与第六连接轴和与第七连接轴连接——的上游被分离,那么以结构上简单的方式车辆动力传动系的与变速器输入轴耦合的驱动机器(例如构成为内燃机的驱动机器)在车辆的各种不同的运行范围内可脱耦。因此例如在同时驱动机器断开的情况下能够以高的效率实施车辆的巡航运行。
如果切换元件至少部分地、优选全部的切换元件构成为摩擦锁合的切换元件,那么在各单个用于前进行驶和倒车的传动比之间的传动比变换至少部分地在没有其它结构措施的情况下可作为无牵引力中断的换挡形成,或者构造有根据本发明的变速器装置的车辆的启动过程可以在无附加的启动元件(例如摩擦锁合的离合器或液力变矩器)的情况下实施。
如果第二行星齿轮组和第三行星齿轮组设置在一个齿轮组平面中并且第二行星齿轮组设置在第三行星齿轮组的径向内部,那么根据本发明的变速器装置的特征在于沿着轴向方向小的构造空间需求。
在根据本发明的变速器装置的沿着径向方向以较小的构造空间需求为特征的进一步构成中,第二行星齿轮组沿着轴向方向设置在第一行星齿轮组的齿轮组平面和第三行星齿轮组的齿轮组平面之间。
在根据本发明的变速器装置的另外的有利的实施方式中,切换元件至少部分地构成为形锁合的和/或摩擦锁合的切换元件,其中摩擦锁合的切换元件有利地作为启动元件和/或用于实施在根据本发明的变速器装置的各单个传动比之间的所谓的无牵引力中断的动力换挡。设计成形锁合切换元件如牙嵌式切换元件的离合器和/或制动器相对于摩擦锁合的切换元件在打开的运行状态中具有较小的损失功率。
变速器装置能够分别在期望的范围上以结构上简单的方式以纵向布置或前置横向布置安装在车辆中,如果切换元件至少部分沿着轴向方向设置在第一行星齿轮组和第二行星齿轮组的齿轮组平面之间。
根据本发明的变速器装置可以优选是机动车的混合动力传动系的组成部分。混合动力传动系除了变速器装置之外还具有构成为内燃机的驱动机器,其可以或者直接地或者经由离合器与变速器装置的变速器输入轴连接。机动车可以在此不仅通过内燃机而且可以通过变速器装置的电机被驱动。可选地,变速器装置为此具有另外的电机,其设置用于经由其转子将转矩传递到变速器输入轴上并且如此启动内燃机。这具有优点,即内燃机借助于另外的电机可以被启动,而不会对于同步的电行驶运行产生影响,在电行驶运行期间,机动车仅仅通过变速器装置的电机被驱动。
电机在此与变换器连接,经由该变速器电机与蓄能器连接。为此每个形式的蓄能器是合适的,特别是电化学的、静电的、液压的和机械的蓄能器。
附加地存在这样的可能性,即将根据本发明的变速器装置在电动车辆的动力传动系中使用。这样的电动车辆例如借助于一个或多个电机可被驱动并且相应地不具有内燃机。在变速器输入轴的区域中在这样的应用中连接所谓的牵引电机。通过变速器装置的各种不同的传动比级,牵引电机分别可在运行范围内以高的效率运行,由此改善整个电动车辆的能量效率。
不仅在权利要求书中给出的特征而且在根据本发明的变速器装置的接下来的实施例中给出的特征分别单独地或任意彼此组合地适合于进一步构成本发明的内容。

具体实施方式
图1示出变速器装置1的第一实施方式,其包括变速器输入轴2、变速器输出轴3和三个行星齿轮组P1至P3,这些行星齿轮组具有总共七个连接轴W1至W7。用于形成至少六个传动比1VM至6VM(在这些传动比时变速器输入轴2和变速器输出轴3以相同的或不同的旋转方向旋转并且在车辆中使用变速器装置1时形成所谓的用于前进行驶的传动比),行星齿轮组P1至P3至少部分地在行星齿轮组P1至P3的行星齿轮组轴S1、ST1、HR1、S2、ST2、HR2、S3、ST3和HR3的区域内彼此作用连接、经由切换元件K1、K2、K3、B1、B2和B3至少部分地彼此可连接并且在行星齿轮组轴S1至HR3的区域内与连接轴W1至W7耦合。
在图2中示出的变速器装置1的第二实施方式与根据图1的变速器装置1的区别基本上仅仅在于,第三行星齿轮组P3设置在第一行星齿轮组的径向内部并且两个行星齿轮组P2和P3定位在相同的齿轮组平面中。由此根据图2的变速器装置1在轴向方向上与根据图1的变速器装置1相比需要较小的构造空间需求。
图3示出根据图1和图2的变速器装置1以及在图4至图9中示出的变速器装置1的实施方式的换挡图,其中在图3中示出的换挡图为了形成规定的变速器装置1的运行状态而处于闭合的运行状态中的切换元件B1至K3分别通过字母X表示。切换元件B1至K3全部构成为摩擦锁合的切换元件。在所有在附图中示出的变速器装置1的实施方式中,分别可以在变速器输入轴2和变速器输出轴3之间形成六个用于前进行驶的传动比1VM至6VM,在这些传动比期间变速器输入轴2和变速器输出轴3以相同的或不同的旋转方向旋转。附加地在根据图1、图2和图4至图9的变速器装置1的构成有设计成制动器的切换元件B3的实施例中附加地可形成两个用于倒车的传动比R1VM和R2VM。
在变速器输入轴2和变速器输出轴3之间的第一前进挡1VM通过闭合构成为制动器的切换元件B1和构成为离合器的另外的切换元件K2得到。当切换元件B1和同时构成为离合器的切换元件K3闭合时,在变速器装置1中挂入第二前进挡2VM。当切换元件B1和另外的构成为离合器的切换元件K1闭合时,而后在变速器装置中挂入第三前进挡3VM。如果在变速器装置1中切换元件K1和切换元件K3同时转移到闭合的运行状态,那么在变速器装置1中形成第四前进挡4VM。如果存在相应的用于挂入第五前进挡5VM的要求,那么切换元件K1和切换元件K2需要被转入到闭合的运行状态中。当切换元件B2和K1同时处于闭合的运行状态时,又在变速器装置1中挂入第六前进挡6VM。
如果车辆应当利用根据图1、图2或图4至图9的变速器装置1在倒车方向上行驶,那么或者切换元件B3和K2或切换元件B3和K3同时需要被保持在闭合的运行状态或转入该运行状态。
根据图10至13的变速器装置1的其它实施例构成为不具有摩擦锁合的制动器B3,因此在根据图10至13的变速器装置1中两个用于倒车的传动比R1VM和R2VM不能形成并且因此在根据图14的适用于变速器装置1的换挡图中未设计。在其它方面根据图14的用于前进行驶的传动比1VM至6VM的换挡图对应于在图3中示出的换挡图,因此就根据图10至13的变速器装置1中形成各单个传动比1VM至6VM的说明而言参照之前的说明。
在附图中示出的变速器装置1的实施方式具有接下来详细描述的变速器结构并且区别分别在于,变速器装置1的一些实施例构成有附加的电机,或者齿轮组在轴向方向上以不同的布置并排地或部分径向嵌套地设置。
因此在所有的变速器装置1中第一连接轴W1分别与第一行星齿轮组P1的第一行星齿轮组轴S1和与固定在壳体上的构件4不可相对旋转地连接,而第二连接轴W2与变速器输入轴2和与第一行星齿轮组P1的第二行星齿轮组轴ST1连接。第三连接轴W3分别与变速器输出轴3和与第三行星齿轮组P3的第二行星齿轮组轴ST3连接。附加地,第四连接轴W4与第一行星齿轮组P1的第四行星齿轮组轴HR1连接并且经由切换元件K3与第七连接轴W7可连接。第五连接轴W5也与第二行星齿轮组P1的第三行星齿轮组轴HR2连接并且与第三行星齿轮组3的第一行星齿轮组轴S3连接以及经由切换元件B1与固定在壳体上的构件4可连接。附加地,第六连接轴W6与第三行星齿轮组P3的第三行星齿轮组轴HR3连接并且与第二行星齿轮组P2的第二行星齿轮组轴ST2连接并且经由切换元件K1与变速器输入轴2可连接,而第七连接轴W7与第二行星齿轮组P2的第一行星齿轮组轴S2连接并且经由切换元件B2与固定在壳体上的构件4可连接并且经由切换元件K2与变速器输入轴2可连接。
所有在附图中示出的变速器装置1的行星齿轮组P1至P3在当前构成为负传动比行星齿轮组,因此行星齿轮组P1至P3的第一行星齿轮组轴分别构成为太阳轮S1至S3,而第二行星齿轮组轴分别构成为行星架ST1至ST3并且第三行星齿轮组轴分别构成为齿圈HR1至HR3。
与之不同,当在行星齿轮组构成为正传动比行星齿轮组时,行星齿轮组的第一行星齿轮组轴分别构成为太阳轮,而第二行星齿轮组轴分别构成为齿圈并且第三行星齿轮组轴分别构成为行星架。
在变速器装置1的在图1和图2中示出的实施方式中这两个切换元件K1和K2设置在变速器的输入侧。在这两个切换元件K1和K2上沿着轴向方向邻接第一行星齿轮组P1的齿轮组平面。在根据图1的变速器装置1的设计中,第二行星齿轮组P2的齿轮组平面设置在第一行星齿轮组P1的齿轮组平面和第三行星齿轮组P3的齿轮组平面之间,其中第三行星齿轮组P3定位在变速器输出侧。附加地切换元件B1至B3和切换元件K3沿着轴向方向设置在第一行星齿轮组P1的齿轮组平面和第二行星齿轮组P2的齿轮组平面之间,因此以结构上简单的方式和方法可以实现变速器输入轴2和变速器输出轴3的同轴布置。
与根据图1的变速器装置1的实施例不同,第二行星齿轮组P2和第三行星齿轮组P3设置在一个共同的齿轮组平面中,第二行星齿轮组P2安装在第三行星齿轮组P3的径向内部。与第二行星齿轮组P2和第三行星齿轮组P3的设置无关,在根据图2的变速器装置1中变速器输出轴3与变速器输入轴也同轴布置,因此根据图1和图2的变速器装置1优选设置用于在机动车中的纵向布置。
在根据图4和图5的变速器装置1的实施方式中变速器输出端侧向设置,因此该变速器装置1的实施方式优选以所谓的前置横向布置应用在车辆中。
在根据图4和图5的变速器装置1中仅仅切换元件K1定位在变速器输入侧,而切换元件B1至B3和切换元件K2和K3设置在行星齿轮组P1(其分别设置在变速器输出侧)和第二行星齿轮组P2之间或在图5中示出的两个行星齿轮组P2和P3的嵌套布置的情况下设置在第一行星齿轮组P1和两个行星齿轮组P2和P3之间。
在图6至9中示出的变速器装置的其它实施例分别附加地包括电机5,其定子6与固定在壳体上的构件4连接并且其转子7与第四连接轴W4连接。因此根据图6至9的变速器装置1形成所谓的混合变速器,其中电机5或其转子7分别经由在第一行星齿轮组P1的区域内的、位于变速器内部的预传动比连接到变速器装置1的力流上。由于电机5经由位于变速器内部的预传动比的连接,电机5与直接连接到力流或变速器输入轴2上的电机相比可较小地和因此便宜地制造。
附加地在变速器输入轴2的区域内可设置其它的切换元件K0或分离元件,其构成为摩擦锁合的离合器。在分离切换元件K0的区域中,与变速器输入轴2作用连接的驱动机器、例如内燃机可与根据图6至图9的变速器装置1的变速器输入端脱离耦合,以便例如经由电机实现纯电动行驶。附加地也存在这样的可能性,即,将这样的驱动机器在分离切换元件K0的区域内脱耦并且在变速器输出轴3的区域中作用的转矩完全用于驱动发电机式运行的电机5并且在电机5的区域中而后可以以高的效率产生电能。
在其它方面根据图6的变速器装置1的变速器结构对应于根据图1的变速器装置1的变速器结构,并且根据图7的变速器装置1的变速器结构对应于根据图4的变速器装置1的变速器结构。附加地根据图8的变速器装置1除了上述的电机5与第四连接轴W4的连接之外与根据图2的变速器装置1具有相同的结构。此外根据图9的变速器装置1具有根据图5的变速器装置1的上述构造,因此就根据图6至9的变速器装置1的其它工作方式而言参照针对图1至图5的上述说明。
根据图10至13的变速器装置1的其它实施例也分别与根据图1至9的变速器装置1在相同范围上构成有电机5。为了然而可以将配备有根据图10至13的变速器装置1的车辆在倒车方向上运行,相应设置电机5的旋转方向并且变速器输出轴3以用于形成倒车运行所需要的旋转方向运行。
在其它方面根据图10的变速器装置1也具有与根据图1的变速器装置1的变速器结构相对应的变速器结构,而根据图11、图12和图13的变速器装置1的变速器结构分别对应于根据图2、图4或图5的变速器装置1的变速器结构,因此就根据图10至13的变速器装置1的其它工作方式而言参照针对图1、图2或图4和图5的说明。
