Description

用于混合动力车辆的驱动系的混合动力模块以及这种驱动系
技术领域
本发明涉及一种用于(混合动力)车辆、诸如客车、货车或其他商用车的驱动系的混合动力模块，混合动力模块具有准备/设计用于将扭矩从内燃机和/或电机，例如电动机传递至变速器的中间轴，中间轴在几何结构上以及在材料特性方面如此设计，使得中间轴可经由两个(支撑)轴承支撑/支承在中间壁上。本发明也涉及用于(混合动力)车辆的驱动系，驱动系具有内燃机、变速器和布置在内燃机和变速器之间的混合动力模块。
背景技术
在现有技术已知的、混合动力模块布置在内燃机和变速器之间的混合动力系统中，混合动力模块的中间轴经由轴承装置支承在中间壁中、支架板等上。这种系统例如由DE10 2015 211 436 A1得知。该公开文献描述了一种驱动装置，驱动装置具有用于与内燃机和与电机连接的输入元件和用于使驱动装置与后置的变速器的变速器输入轴连接的输出元件，其中作为起动元件设置摩擦离合器，摩擦离合器使电机的转子与输出元件耦合，并且驱动装置具有牙嵌离合器，牙嵌离合器使得内燃机在摩擦离合器接合时与摩擦离合器的输入元件耦合。
在已知的系统中，中间轴实施成，使得在驱动机侧可建立与分离离合器(K0离合器)的连接，例如经由带有齿部的盘毂来连接。在变速器侧，中间轴设有法兰面，以可以建立与起动离合器(K1离合器)的连接。在此这种起动离合器可实施成单离合器、双离合器或多盘离合器。
在已知的系统中，中间轴从变速器侧安装到中间壁中。分离离合器例如借助轴毂连接部布置在中间轴上并且从驱动机侧沿轴向固定，例如经由螺旋连接固定。可替代地，分离离合器也可经由螺母、止动环或类似的锁止元件沿轴向固紧在中间轴上。
已知系统的缺点是，驱动机侧的构件的轴向固定部位于中间轴的驱动机侧上，并且用于变速器侧的构件的轴向固定在变速器侧进行。由此使得安装非常复杂并且可能浪费结构空间，因为需要两个锁止元件使部件沿轴向固定在中间轴上。
发明内容
本发明的目的是，避免或至少减少现有技术中的缺点，并且尤其不仅驱动机侧的构件而且变速器侧的构件的轴向固定部相对于中间轴设置在变速器侧。
由此可取消单独的、布置在驱动机侧的轴向固定部。
根据本发明，本发明的目的在这种类型的混合动力模块中通过以下方式实现：在中间壁的变速器侧上的锁止元件，例如螺钉、螺母和/或固定构件组合确定/规定可在中间壁的驱动机侧安装在中间轴上的扭矩传递构件、例如分离离合器(K0离合器)的轴向位置。
由此对于离合器制造商以及对于终端客户都得到安装工艺的优点。因此还可实现结构空间优点，因为可取消例如盘毂、连接元件等构件并且可使构件更好地互连。
有利的实施方式在从属权利要求中被保护并且在下面进行阐述。
由此有利的是，混合动力模块经由两个(支撑)轴承支承/支撑在中间壁上。
在此，两个轴承同样从变速器侧开始被推到中间轴上。
此外有利的是，通过锁止元件沿轴向固定关于中间壁布置在变速器侧上的飞轮，飞轮以传递扭矩的方式连接在中间轴上。
在此，飞轮可为布置在变速器侧的起动离合器(K1离合器)的一部分。通过将飞轮固定在中间轴上可取消K1离合器在中间轴上的单独连接。由此实现更紧凑的构造方式。
在此已经发现有利的是，飞轮具有法兰区段，法兰区段布置在优选较靠近变速器的(支撑)轴承和中间轴之间。因此，变速器侧的飞轮承载轴承中的一者并且在内直径上经由接口或连接部、例如齿部设置到中间轴上。
在此有利的是，飞轮的法兰区段布置在优选较靠近变速器的例如设计成滚动轴承的(支撑)轴承的内圈和中间轴的外侧之间。
在法兰区段的该设计方案中，已经发现作为有利的是，法兰区段的驱动机侧的端面与(支撑)轴承中的、优选较靠近发动机的另一者的优选侧面/端侧接触。
由此，较靠近发动机的支撑轴承经由飞轮的法兰区段从一侧沿轴向定位。
在此有利的是，中间轴的外直径从驱动机侧朝变速器侧基本优选阶梯式地减小。
此外有利的是，中间轴在驱动机侧具有法兰状的径向的突出部，突出部优选与中间轴一件式构造。
该突出部可用于固定支架元件，例如在轴平行的混合动力系统中的具有皮带轨道的支架板，或者在同轴的混合动力系统中的转子支架。此外，突出部用作止挡或限制装置，其用于从另一侧沿轴向定位较靠近发动机的支撑轴承。
在此已证实适宜的是，中间轴的外直径尤其从例如可用作止挡面的法兰状的径向突出部开始朝变速器侧的方向逐渐减小。在法兰状的突出部的驱动机侧上可如此调节中间轴的直径，使得中间轴的该部分可用于安装(在驱动机侧)布置在中间轴上的其他构件。
在此有利的是，突出部用作用于分离离合器(K0离合器)的连接部或用于固定分离离合器。
此外，本发明也涉及用于(混合动力)车辆的驱动系，驱动系具有内燃机、变速器和布置在内燃机和变速器之间的根据本发明的混合动力模块。
换句话说，本发明在于使轴向固定部(螺钉)从中间轴的驱动机侧移位到变速器侧。变速器侧的飞轮承载轴承中的一者并且在内直径上具有用于中间轴的接口或连接部(齿部)。相比于现有技术，中间轴本身几乎镜像对称。中间轴的法兰面用作与内侧离合器片支架(具有皮带轨道的支架板)的连接部。在中间轴上安置有另一轴承。该实施方式不仅可用于轴平行的混合动力系统而且也用于同轴的混合动力系统，所谓的P2混合动力系统。
换句话说，从变速器的一侧沿轴向将分离离合器(K0离合器)固定在中间轴上。变速器侧上的飞轮支承/支撑一个轴承并且在内直径上具有法兰区段，以使飞轮与中间轴耦合。中间轴的法兰区段连接中间轴与内侧离合器片支架或具有皮带轨道的支架板。另一轴承布置在中间轴上。该布置可应用在轴平行的或同轴的混合动力系统中。

各个实施例的特征也可在其他的实施例中实现。即他们可彼此交换。
具体实施方式
图1示出了混合动力模块1的剖视示意图，混合动力模块构造成所谓的P2混合动力模块。P2混合动力模块理解为这样的混合动力模块，其在车辆的驱动系中布置在内燃机(图1中向左)和变速器(图1中向右)之间。
混合动力模块1具有中间轴2，中间轴经由两个(支撑)轴承3、4支承在中间壁5上。参考中间壁，区分中间轴2的变速器侧6(在图1中在中间壁5的右侧)和驱动机侧7(在图1中在中间壁5的左侧)。
在中间壁5的驱动机侧7布置分离离合器(K0离合器)9，其用于将内燃机或电机以传递扭矩的方式与中间轴2连接。在变速器侧布置起动离合器(K1离合器)10，其经由飞轮11与中间轴2以传递扭矩的方式连接。布置在中间轴2上的构件，尤其如起动离合器10或飞轮11经由锁止元件8从变速器侧6开始沿轴向定位。
此外，在中间轴2的左侧示出了双质量飞轮12，双质量飞轮用于衰减内燃机的振动和振荡。在中间轴2的右侧示出了起动离合器10，起动离合器具有飞轮11以及尤其离合器盘13和离合器压板14。起动离合器10用于从中间轴2至变速器的扭矩传递或中断从中间轴至变速器的扭矩传递(未示出)。
分离离合器9布置在中间轴2上并且经由内侧离合器片支架15固定在中间轴2的法兰状的径向突起部16上。在此处示出的实施方式中，内侧离合器片支架15实施成具有皮带轨道18的支架板17，支架板在必要时将电机、例如电动机(此处未示出)的扭矩经由分离离合器9传递到中间轴2上。
这种实施方式尤其对于轴平行的混合动力装置是优选的。可替代地，代替皮带轨道18也可想到固定用于电机的转子的转子支架。该实施方式尤其对于同轴的混合动力系统是优选的。
分离离合器9在此作为“常闭”离合器示出，这表示，分离离合器在未被操作的状态下是闭合的并因此与内燃机以传递扭矩的方式连接。通过操作分离装置19断开分离离合器9并因此与电动机以传递扭矩的方式连接。
下面根据图2详细描述构件在中间轴2上的正确布置和定位。
图2示出了混合动力模块1，混合动力模块在图1中布置在内燃机(在图1中左侧，未示出)和变速器(在图1中右侧，未示出)之间。为了简单地示出对于本发明重要的构件，在图2中除了飞轮11没有示出分离离合器9以及起动离合器10。关于分离离合器9仅示出了呈具有皮带轨道18的支架板17形式的内侧离合器片支架15。
除了关于中间壁5在驱动机侧布置在中间轴2上的、法兰状的径向向外伸出的突出部16，中间轴2具有从驱动机侧7朝变速器侧6基本减小的直径。中间轴2和突出部16在此一件式构造。法兰状的突出部16用于固定内侧离合器片支架15或与内侧离合器片支架连接，在此处示出的实施例中，内侧离合器片支架借助铆钉20固定在突出部16上。可替代地，代替铆钉20也可想到另外的连接元件，例如螺钉等。另一方面，法兰状的突出部16用作较靠近发动机的轴承4的内圈21的止挡面，在将内圈朝一个方向(在图2中向左)推到中间轴2上时，止挡面限制沿内圈21的轴向的运动。
轴承3、4在此构造成滚动轴承、确切地说球轴承。但是也可想到其他的滚动轴承类型，例如滚柱轴承等。两个轴承3、4将中间轴2支撑在中间壁5上，或者说将中间轴2支承在中间壁5上/中。(支撑)轴承3在此构造成角接触球轴承并且以其外圈22在侧面与中间壁5(的突出部)接触。较靠近变速器的轴承3的内圈23布置在飞轮11的法兰区段24上或被推到飞轮的法兰区段上。在此，内圈23的侧面贴靠在飞轮11上。
飞轮11的法兰区段24在轴向上从飞轮11向图2中左侧(远离起动离合器10地)延伸并且在其内直径上具有接口或连接部25，借助其将飞轮11以传递扭矩的方式与中间轴2连接。接口25例如构造成轴毂连接部的形式。由此，中间轴2与推入/布置在其间的法兰区段24经由轴承3支撑在中间壁5中/上。
此外，法兰区段24用于通过以下方式轴向确定或定位较靠近发动机的轴承4的内圈21：将法兰区段24的驱动机侧的端面26贴靠在内圈21的变速器侧的侧面27上。
布置在中间轴2上的构件，尤其例如轴承3、4、分离离合器9(参见图1)和飞轮11在变速器侧经由此处呈螺钉28形式的锁止元件8沿轴向以确定方式的定位。
可替代地，作为锁止元件也可想到螺母、锁止环或类似的锁止元件以及多个元件的组合、所谓的锁止元件组合。
通过此处示出的中间轴2的构造方式和构件的布置，可仅借助锁止元件8从变速器侧6开始沿轴向将构件固定或定位在驱动机侧7(即，中间壁5的左侧)以及变速器侧6(即，中间壁5的右侧)上。
图3至图8示出了内侧离合器片支架的不同实施方式。
内侧离合器片支架15尤其用于使离合器片(未示出)对中或引导离合器片，用于传递内燃机的扭矩，用于传递电机的扭矩以及用于提供至中间轴以及至电机、例如电动机的接口。
在图3至图8中，内侧离合器片支架15实施成多件式。通过多件式的实施方式可通过更少的成型步骤制造复杂几何结构的内侧离合器片支架15。此外，关于各个构件的材料强度差异、材料选择和热处理方面的自由度是可实现的。
在此处示出的示例性的实施方式中的内侧离合器片支架15具有内笼架29、具有皮带轨道18的支架板17和用于中间轴2的连接元件30，连接元件在此构造成盘毂31的形式。尤其在内侧离合器片支架15以不同方式、例如图2所示地与中间轴2连接时，也可取消连接元件30。
内笼架29具有多个沿着内笼架29的周向分布的指部32，指部在图3中的轴向方向A上延伸。支架板17具有与其对应的沿着周向布置的窗口/凹口/开口33，指部32在安装时接合到其中(参见图4)。盘毂31例如借助多个沿着盘毂31的周向布置的螺钉34(参见图4)固定在内笼架29上。
在指部32分别穿过并插接到与其对应的窗口33(参见图4)之后，指部32沿轴向从窗口33伸出并且借助成型过程、例如滚压或冲压来成型，使得内笼架29和支架板17不可分开地连接。如在图5中所示，这种成型过程可使指部32的穿过窗口33的端部成型为封闭体部35。以这种方式产生类似于铆接的形状配合连接，但是其中取消额外的连接元件，例如铆钉。
图6在放大的示意图中示出了借助封闭体部35的形状配合连接。通过在内笼架29和支架板17之间的这种连接可取消重叠的几何结构，如对于螺旋连接或铆接所需的几何结构，由此实现紧凑的实施方式并因此减小结构空间。相比于焊接连接，这种形状配合连接没有焊接变形并且没有在材料方面的限制。
作为可替代的连接类型，也可考虑压嵌部，其例如在离合器盘中已知的用于连接盘毂和盘毂法兰。
图7和图8示出了内侧离合器片支架15的另一不同实施方式，在其中连接元件30实施成盘毂31的形式并且与内笼架29实施成一件。在此盘毂31的区域类似于锻造盘毂来实施并且由内笼架29深拉出来。
通过内侧离合器片支架15的多件式实施方式，各个构件可由不同的材料和/或不同的材料厚度制成。有利的组合在此例如为以下布置方式：扭矩导入元件由例如锻造钢或铸造材料制成盘毂31的形式。内笼架29由具有用于离合器片的啮合部的板材制成，并且具有皮带轨道18的支架板17(作为皮带盘类型)同样由板材、但是具有不同的板材厚度的板材制成。在盘毂31和内笼架29之间的连接部位经由铆钉实现，而在内笼架29和支架板17之间的连接部位经由所述成型方法例如以滚压处理的方式实现。
