Description
技术领域
本公开总体涉及变矩器,且更特别地涉及变矩器的芯环。
背景技术
通常,如图1中的剖视透视图所示,变矩器的涡轮或叶轮的芯环110包括滚圆的外径112,该外径112是芯环110的弯曲叶片侧表面114的一部分。在外径112处,叶片侧表面114与径向延伸边缘116的外径相接,该径向延伸边缘116垂直于芯环110的中心轴线延伸。在其内径处,叶片侧表面114相接于内径边缘120,该内径边缘120从叶片侧表面112的内径轴向地且径向地向外延伸,以相接于芯环110的弯曲定子侧表面122的内径。定子侧表面122从弯曲的定子侧表面122径向向外延伸、同时以较小程度轴向延伸到径向延伸边缘116的内径。芯环110具有恒定的厚度,且叶片侧表面112和定子侧表面122都沿循相同的弯曲路径,同时从边缘120径向向外且轴向延伸至边缘116。用于接收涡轮或叶轮叶片的连接凸台的槽124形成在芯环110的内部,即在边缘116,120之间,且从定子侧表面122穿过芯环110到叶片侧表面112。
还已知在径向延伸的边缘116中提供从表面114延伸到表面122的截切部126,如图2所示。截切部126仅用于制造目的,且对芯环的性能没有任何影响。截切部126在承载凸台的两侧上保持部件附接到条带上,并提供拉伸接板以使材料在形成期间流动。仅通过切割外径上的承载凸台,该部件在级进模的最后一个工位中被冲出。如果施加高压,则截切部126可引起弱点(应力上升)。这些是可能失效的区域。
发明内容
提供了一种用于变矩器的叶轮或涡轮的芯环。芯环包括:环形的基底部分,其包括凸式叶片侧表面部分和凹式定子侧表面部分;和卷绕的外径部分,其包括从环形的基底部分径向向外突出的向外延伸式唇缘。
还提供了一种变矩器。变矩器包括:涡轮;叶轮;和定子,其将流体流从涡轮重引导回叶轮。涡轮和叶轮中的至少一个包括芯环。
附图说明
下面参考附图描述本发明,其中:
图1示出了传统芯环的剖视透视图;
图2示出了另一种已知的芯环的透视图;
图3示出了根据本发明的一个实施例的变矩器的剖视侧视图;以及
图4示出了图3中所示的变矩器的芯环的剖视透视图。
具体实施方式
提供了一种包括卷绕的外径的芯环。当施加高压时,由芯环的卷绕的外径形成的唇缘为部件提供了额外的刚度。提供卷绕的外径允许较薄的材料或较弱的材料用于芯环,且仍然为部件提供足够的强度以承受应用中所需的力。此外,具有外唇缘的卷绕的外径使用所谓的洋葱圈切口连接到条带,所述洋葱圈切口在形成期间提供材料流动。接下来,部件被完全切除,因此外径上不需要截切部。因此,所得到的芯环更刚硬,且在芯环的外径上没有任何由截切部引起的应力上升
图3示出了根据本发明的一个实施例的变矩器10的剖视侧视图。变矩器10可绕中心轴线11旋转,且包括用于连接至内燃机曲轴的前盖12和形成叶轮或泵18的壳16的后盖14。在此所使用的术语轴向、径向和周向是相对于中心轴线11而言。变矩器10还包括与叶轮18相对的涡轮20和轴向地位于叶轮18和涡轮20之间的定子22。涡轮20包括多个叶片24,叶片24在涡轮壳26的后盖侧支撑在涡轮壳26的滚圆部分上,且支撑在根据本发明的一个实施例的芯环28上。涡轮20还包括从滚圆部分26径向向内突出的内径向延伸部30。在涡轮20的前盖侧,涡轮20连接到减振组件32。
减振组件32包括CPA 34,CPA 34形成在第一盖板36的径向外端处,第一盖板36通过铆钉38铆接到涡轮20的内径向延伸部30。减振组件32还包括轴向地位于第一盖板36和前盖12之间的第二盖板40,盖板36,40在其间轴向地支撑多个周向间隔开的径向靠内的成组的弹簧42。减振组件32包括轴向地夹在盖板36,40之间的驱动法兰44,驱动法兰44的内径向端部构造成毂45,用于连接到变速器输入轴。驱动法兰44包括形成在其中的多个周向延伸的槽,用于接收弹簧42。在弹簧42的径向外侧,减振组件32还包括多个周向间隔开的径向靠外的成组的弹簧46。第二盖板40的径向外端部形成用于接收弹簧46的弹簧保持器48。
活塞50设置在前盖12和减振组件30之间,离合器板52轴向地设置在活塞50和前盖12之间。离合器板52在其径向外端处包括多个周向间隔开的突出部54,用于延伸到形成于弹簧42之间的周向空间中。离合器板50在其径向内端处在其前盖侧上设有摩擦材料,以用于接合前盖12的内轴向表面;且在其后盖侧上设有摩擦材料,以用于接合活塞50。活塞50、离合器板52和前盖12的内轴向表面形成锁止离合器,以用于通过减振组件30将涡轮20驱动地耦合到前盖12。活塞50的前盖侧和活塞50的后盖侧之间的流体压力差控制活塞50与前盖12接合还是脱离。盖板36,40将扭矩从涡轮20传递到驱动法兰44,驱动法兰44进而驱动变速器输入轴。盖板36,40共同将扭矩传递到弹簧46,弹簧46将扭矩传递到离合器板52。
叶轮18还包括多个叶片56,叶片56在叶轮壳16的前盖侧支撑在叶轮壳16的滚圆部分上,且支撑在根据本发明一个实施例的芯环58上。
图4示出了根据本发明一个实施例的芯环28或芯环58的剖视透视图。芯环28,58包括卷绕的外径部分60,外径部分60包括具有环形形状的径向向外延伸式唇缘62。卷绕的外径部分60意味着不是沿循芯环的指示的弧形曲率,而是外径朝着相应的涡轮或叶轮叶片24,56(图3)的径向延伸的边缘24a,56a径向向外地卷绕。芯环28,58在其内径处的叶片侧表面64与内径边缘66相接,并从内径边缘66径向向外延伸。叶片侧表面64具有凸式部分68,凸式部分68包括与内径边缘66邻接的内弯曲区段70,内弯曲区段70在其从内径边缘66径向向外延伸时轴向地远离定子22(图3)弯曲。于是,内弯曲区段70在轴向峰部72处过渡到中间弯曲区段74,该轴向峰部72是芯环28,58的轴向最远离定子22的环形表面,该中间弯曲区段70在它径向向外延伸时,朝着定子22轴向弯曲回来,且内弯曲区段70和中间弯曲区段74限定出凸式部分68。在形成中间区段74的外边缘的过渡区段76处,叶片侧表面64从凸式部分68过渡到形成凹式部分78的外弯曲部分77,其形成了卷绕的外径部分60的叶片侧表面。凹式部分78朝着定子22轴向弯曲并相接于外径边缘80,外径边缘80轴向延伸且平行于中心轴线11(图3)。
芯环28,58的定子侧表面82在其内径处与内径边缘66相接,并从内径边缘66径向向外延伸。定子侧表面82具有凹式部分84,凹式部分84包括与内径边缘66邻接的内弯曲区段86,内弯曲区段86在它从内径边缘66径向向外延伸时轴向远离定子22(图3)弯曲。于是,内弯曲区段86在轴向峰部88处过渡到中间弯曲区段90,该轴向峰部88是芯环28,58的轴向最远离定子22的环形表面,该中间弯曲区段90在它径向向外延伸时,朝着定子22轴向弯曲回来,且内弯曲区段86和中间弯曲区段90限定出凹式部分84。在形成中间区段90的外边缘的过渡区段92处,定子侧表面82从凹式部分84过渡到形成凸式部分94的外弯曲部分93,其形成卷绕的外径部分60的定子侧表面。凸式部分94朝着定子22轴向弯曲,且相接于外径边缘80。内径边缘66、叶片侧表面64的凸式部分68和定子侧表面82的凹式部分84共同限定出芯环28,58的环形的基底部分96,而外径边缘80、叶片侧表面64的凹式部分78和定子侧表面82的凸式部分94限定出从环形的基底部分96径向向外突出的环形唇缘62。芯环28,58可被冲压,以同时形成环形的基底部分96和环形唇缘62。
用于接收涡轮或叶轮叶片的连接凸台的叶片凸台接收槽98形成在基底部分96的内部,即,在边缘66和过渡区段76,92之间,且从定子侧表面64的凸式部分68延伸到叶片侧表面82的凹式部分84。
在前述说明书中,已经参考特定示例性实施例及其示例描述了本发明。然而,显而易见的是,在不脱离权利要求中阐述的本发明的更广泛精神和范围的情况下,可对其进行各种修改和改变。因此,说明书和附图应以说明性方式而非限制性意义来看待。
