Description

具有深拉凸缘的飞轮组件
技术领域
本发明涉及飞轮组件,该飞轮组件优选地用在具有电动起动马达的扭矩传递装置中或者用在传动装置中,优选地用于比如摩托车的机动车辆,飞轮组件具有通过深拉形成的单件式凸缘以及具有容置在外环式飞轮单元内的与外环的夹持斜坡配合的多个滚动体,其中,外环经由压配部紧固在凸缘的套筒部分中。
背景技术
通用类的飞轮组件已经在现有技术中充分已知。例如,DE 10 2016 218 714 B4公开了具有飞轮和凸缘的飞轮组件。
从现有技术中已知的设计的缺点是,当这些飞轮组件由客户进行安装时,在将这些飞轮组件连接至其他部件时通常存在相对较高的工作量。
因此,本发明的目的是消除现有技术中已知的缺点,并且特别是提供一种允许在相应的应用领域中进行可靠安装的飞轮组件。
发明内容
根据本发明实现的是,在凸缘的从套筒部分径向地向外凸出的盘部分的端面上形成有定心套环。定心套环因此被理解为凸出部,该凸出部从凸缘/盘部分轴向地突出并且该凸出部形成有径向支承表面/定心表面。
该定心套环显著简化了进一步的组装,同时凸缘仍然可以通过深拉尽可能简单地生产。
其他有利的实施方式通过从属权利要求来要求保护并且在下面更详细地说明。
因此,如果定心套环通过由深拉技术形成的凸出部形成则也是有利的。以这种方式,制造工作进一步简化。
为了可以连接至凸缘的其他部件的简单组装和简单设计,如果定心套环形成有径向向外指向的优选环形/完全周向的支承表面,则也是有利的。
如果在位于定心套环的径向外侧的盘部分中制成有分布在周向方向上的多个通孔,则能够使飞轮组件的组装具有良好的可接近性,例如经由螺纹连接。
对于紧凑的轴向设计,如果外环具有与套筒部分相同的长度(轴向范围),则也是有利的。
如果在(盘部分的)背对具有定心套环的第一端面的第二端面上压制有周向凹槽,则也是有利的。
套筒部分有利地具有比定心套环的外径小的外径。
如果凹槽布置成与定心套环的径向高度相同,则盘部分可以在轴向和径向上以特别紧凑的方式实现。
此外,有利的是,在沿轴向方向观察时,盘部分布置成偏心于套筒部分。
在这种情况下,已经发现有利的是,套筒部分和盘部分相对于彼此布置成使得凸缘作为整体具有(基本上)L形横截面区域。
换言之,根据本发明,实现了与拉制的凸缘相结合的套筒飞轮(飞轮单元)。深拉凸缘借助于压配合部进行连接。
在下文中,现在将参照附图对本发明进行更详细地说明。
附图说明
在附图中:
图1示出了根据本发明的根据优选示例性实施方式的飞轮组件的纵向截面图,
图2从背对定心套环的端面以完整视图示出了飞轮组件的立体图,
图3从具有定心套环的端面示出了飞轮组件的立体图,
图4示出了飞轮组件的部分分解图,其中,飞轮单元具有尚未被按压到凸缘中的外环和多个滚动元件,以及
图5示出了如何使用如图1至图4中示出的凸缘的立体图。
这些图在本质上只是示意性的,并且仅用于理解本发明。相同的元件设置有相同的附图标记。
具体实施方式
根据本发明的飞轮组件1——通过图1在飞轮组件的结构方面图示了飞轮组件——具有单件式凸缘2,该凸缘在凸缘的径向内部上牢固地接纳飞轮单元6。飞轮组件1用在具有电动起动马达的摩托车的扭矩传递装置中的优选应用领域中。在其他实施方式中,飞轮组件1还用在机动车辆的其他领域中,例如,用在传动装置中。
如图1中示出的,飞轮组件1具有中心旋转轴线17。下面使用的方向、即轴向地、径向地和在周向方向上均与该旋转轴线17有关。因此,轴向地/轴向方向是沿着旋转轴线17的方向,径向地/径向方向是垂直于旋转轴线17的方向,并且周向方向是沿着围绕旋转轴线17同轴地延伸的圆形线的方向。
如在图1和图4中可以看出的,飞轮单元6具有外环3。外环3在该外环的径向内侧直接形成有多个夹持斜坡4,这些夹持斜坡在周向方向上彼此偏移,其中每个夹持斜坡与滚动元件5相互作用。滚动元件5在飞轮锁定在一个旋转方向上的意义上以套筒飞轮的形式与夹持斜坡4配合。滚动元件5实现为滚子,但也可以在其他实施方式中以其他方式实现。滚动元件5各自经由相应的弹簧18在周向方向上被预加应力。滚动元件5也借助于保持架19进行导引。
如图1中示出的,在飞轮组件1的完全组装状态下,外环3被按压到凸缘2的套筒部分8中,即借助于压配合部7进行固定。在该实施方式中变得明显的是,外环3具有与套筒部分8相同的轴向范围/长度。套筒部分8在轴向方向上延伸。
正如还可以结合图2至图5看出的,凸缘2的盘部分10从套筒部分8直接径向地向外延伸。该盘部分10与套筒部分8一起形成大致L形横截面的区域16。盘部分10因此相对于套筒部分8的轴向中心偏移,即布置成偏心于套筒部分8。盘部分10形成设置有轴向通孔13的典型的凸缘区域,通孔布置成在周向方向上彼此偏移。经由通孔13,凸缘2可以在组装位置下使用紧固装置、优选螺钉而附接至相应的部件。
根据本发明,在盘部分10的(第一)端面9上直接形成有定心套环11。例如,如在图3中可以看出,该定心套环11通过第一端面9上的环形凸出部20实现,该环形凸出部完全围绕圆周延伸并且轴向地凸出。定心套环11具有径向地向外指向的环形支承表面12,在操作期间,机动车辆的其他部件的对应的配对部搁置在该支承表面上。定心套环11与旋转轴线17同心地延伸。沿径向方向观察,定心套环11与定心套环的支承表面12一起布置在套筒部分8与通孔13之间。特别地,定心套环11的外径大于套筒部分8的外径(在背离第一端面9的第二端面14上),但定心套环布置在通孔13的径向内侧。在第二端面14上,盘部分10中形成有呈周向凹槽15形式的轴向凹部。凹槽15与定心套环11的径向高度相同。
凸缘2实现为深拉元件,其中,盘部分10、套筒部分8和定心套环11以及优选地还有凹槽15在深拉步骤中一起形成,即借助于工具在深拉过程中一起形成。
换言之,根据本发明,深拉凸缘2与套筒飞轮6(FRAX飞轮)结合地提供。具有模制到后侧部9上的定心套环11的L形凸缘2借助于压配合部7连接至FRAX飞轮6。在最终客户处,凸缘2然后通过螺钉附接至壳体。
