Abstract

本发明为用于混合动力车辆的扭矩转换器挠性板。一种总成，其包括与轴线同心并且包括外壳的扭矩转换器、为了围绕轴线的旋转而可驱动地连接至电机的转子毂、连接至转子毂的耦合器，以及为了弹性位移而耦接在耦合器和背对着耦合器的外壳的表面之间的挠性板。

Description

用于混合动力车辆的扭矩转换器挠性板
技术领域
本发明涉及一种用于混合动力车辆的动力传动系统，特别涉及位于发动机输出和变速器输入之间并且固定至发动机输出和变速器输入的动力传动系统模块。
背景技术
混合动力车辆(HEV)具有内燃发动机和电机两者，内燃发动机和电机两者交替地或结合地用于推动车辆。比如并联配置这样的各种不同的动力传动系统在混合动力车辆中使用，在并联配置中，发动机通过分离式离合器连接至电动机，同时电动机驱动自动动力变速器的扭矩转换器输入。变速器具有连接至耦接至车辆的两个从动车轮的差速器的输出。
工业中存在对混合电力动力传动系统的需求，混合电力动力传动系统包括供与各种发动机和变速器一起使用的模块化子总成，使得模块可以安装在多个发动机中的一个的输出和多个变速器中的一个的输入之间并且固定至多个发动机中的一个的输出和多个变速器中的一个的输入。装配的动力传动系统然后可以在各种车辆中使用。模块应该包括液压驱动的分离式离合器、电机以及在发动机和电机之间至变速器输入的合适的动力路径。优选地，模块提供用于从变速器的液压系统至离合器、平衡坝状部(balance dam)和电机的液压连通。模块必须提供包含运送至模块的液压液体的油槽和用于将该液体不断地返回至变速器的油槽的路径，以便变速器泵不断可靠地供应液体。
该模块有时被称为前端模块(FM)，因为它是模块化混合动力变速器(MHT)的一部分并且用螺栓安装在变速器的前面。由于该模块增加了动力传动系统的长度，所以模块应该尽可能的短。FM上的挠性板和扭矩转换器之间的常规附接不提供扭矩转换器通常具有的通向导致动力传动系统的增加的长度的挠性板的通道。
发明内容
一种总成，其包括与轴线同心并且包括外壳的扭矩转换器、为了围绕轴线的旋转而可驱动地连接至电机的转子毂、连接至转子毂的耦合器，以及为了弹性位移而耦接在耦合器和背对着耦合器的外壳的表面之间的挠性板。
总成包括深冲挠性板(deep drawn flex plate)，挠性板围绕扭矩转换器的前面达到扭矩转换器的背部在螺栓径向地安装的地方，而没有增加前端模块和变速器的前部表面之间的轴向尺寸。
从下面的具体实施方式、权利要求和附图，优选实施例的适用范围将变得显而易见。应该理解，描述和具体的示例——尽管表明本发明的优选实施例——仅以说明的方式给出。关于描述的实施例和示例的各种变化和修改，对本领域技术人员来说将变得显而易见。
附图说明
通过参考下面的描述连同附图，本发明将更容易理解，在附图中：
图1A和1B构成动力传动系统模块的侧面剖视图，表明至发动机输出的前部连接和至变速器扭矩转换器输入的后部连接。
图2是图1的动力传动系统的侧面剖视图，表明具有用螺栓安装的、集成的挠性板的扭矩转换器；

图4是图3的动力传动系统的侧面剖视图，表明连接转子毂和扭矩转换器外壳的后部表面的挠性板。
具体实施方式
图1A和1B说明用于混合动力车辆的动力传动系统的模块10，模块10包括：具有旋转输出12的发动机；扭转阻尼器14，其固定至发动机输出12；输入轴16，其通过花键18固定至阻尼器14的输出20；分离式离合器22，其支承在通过花键26固定至输入轴16的离合器毂24上；电机28，其包括用螺栓安装至前部隔板32的定子30和通过第一腿状部36和第二腿状部38支承围绕轴线39的旋转的转子34；转子毂40，其优选地通过焊接点固定至腿状部38；以及挠性板42，挠性板42在一端通过花键连接44或通过螺栓110固定至转子毂40并且在相对端通过螺栓46固定至扭矩转换器外壳48，扭矩转换器外壳48封闭液力扭矩转换器49。电机28可以是电动机或电动发电机。
适合于在动力传动系统中使用的扭矩转换器在参考2011年12月14日提交的美国专利申请号13/325,101的图4a、4b、5、12和15中公开和描述，该美国专利申请文件的全部公开通过引用合并于此。
扭矩转换器49包括：位于外壳48里面并且固定至外壳48的叶片叶轮；叶片涡轮，其通过叶轮液压动力地驱动并且通过花键50固定至自动变速器54的输入轴52；以及叶片定子轮，其位于涡轮和定子之间并且固定至定子轴56，叶片定子轮保持在变速器外壳58上不旋转。
通过螺栓62固定至变速器外壳58的后部隔板60，用液压密封件64安装在它的径向内表面上，液压密封件64接触转子毂40的径向外表面。
通过螺栓68固定至发动机的旋转输出12的飞轮66，承载发动机启动齿轮70，启动齿轮70通过焊接至启动齿轮和飞轮的圆盘72固定。
轴承74支承第一腿状部36在前部隔板32上的旋转。轴承76支承第二腿状部38在转子毂40上的旋转。与轴线39对准并且支承转子34围绕轴线的旋转的管78，固定至第一腿状部36和第二腿状部38。分别在管78的前端和后端的唇状部80、82可以径向向外地卷以将转子34固定至管78并且阻止转子34相对于管的轴向位移。管78的内表面由轴花键81形成，轴花键81接合腿状部36、38和分离式离合器22的间隔板83。离合器22的摩擦板84通过形成在离合器毂24的径向外表面上的轴花键固定。
用于驱动离合器22的液压伺服包括活塞86、平衡坝状部88、回位弹簧90以及用于将驱动压力传递至在活塞86的右边的压力控制体(pressurecontrol volume)92并传递至在活塞的左边的压力平衡体94的液压管路。当驱动压力且液压液体供应至体92时，活塞86通过使用密封件151和152在由后部腿状部38形成的圆柱体中向左移动，因此引起离合器22接合转子34和发动机输出12并且通过阻尼器14、输入轴16、离合器毂24以及离合器22可驱动地连接转子34和发动机输出12。
由于活塞86、平衡坝状部88和回位弹簧90支承在转子毂40上，活塞86、平衡坝状部88和回位弹簧90的转动惯量位于输出侧即离合器22的转子侧。
转子34通过扭矩路径不断可驱动地连接至变速器输入轴52，扭矩路径包括后部腿状部38、转子毂40、挠性板42、扭矩转换器外壳48、扭矩转换器叶轮和涡轮之间的液力驱动连接，液力驱动连接通过花键50连接至变速器输入轴52。
用于测量旋转的角度的旋转电力变压器的高度精确类型——分解器100，通过螺栓102固定至前部隔板32、支承在前部隔板32和第一腿状部上，并且轴向地位于前部隔板32和后部隔板60之间。
花键44的齿——其在挠性板42和转子毂40之间产生旋转驱动连接——安装在一起，使得当扭矩在挠性板和转子毂之间传递时不产生空隙。挠性板42由具有在腹板(web)108上终止的螺纹孔106的厚壁部分104形成。通过接合转子毂40的右端中的螺纹孔的螺栓110，挠性板42上的外部花键齿被促使与转子毂40上的内部花键齿轴向地接合。一俟移除螺栓110并且将较大的螺栓穿入孔106中，在花键连接44上的接合的花键齿脱离，使得螺栓接触腹板，因此促使挠性板轴向向右。
转子毂40由多个轴向定向的液压通道120和横向定向的通道122、124、126、128、129形成，通道从变速器54的液压系统输送液压液体和压力至模块10。通道122、124、126、128、129输送包括：至位于活塞86的右边的离合器22的伺服的控制体92，至在平衡坝状部88和活塞之间的压力平衡体94，至变力电磁阀(VFS)130，以及至转子34和定子30的表面——该表面通过液体冷却——的液压液体和压力。后部隔板60由通道128形成，通道128与VFS130液压地连通。
后部隔板60支承液箱132，液箱132包含从变速器54的液压系统供应至模块10的液体。变速器54包括液箱136，液箱136包含通过变速器泵134供应至变速器液压系统的液压液体，液体和控制压力从变速器液压系统供应至模块10、扭矩转换器49、变速器离合器和制动器、轴承、轴、齿轮等。
安装在前部隔板32中的轴承140和安装在转子毂40中的轴承142，支承输入轴16围绕轴线39的旋转。前部隔板32还支承相对于转子34在它的适当的轴向和径向位置中的定子30。安装在后部隔板60和转子毂40之间的轴承76和轴承142支承转子毂40围绕轴线39的旋转。前部和后部隔板32、60由于安装在隔板32中的轴承74和安装在隔板60中的轴承76，共同支承转子34围绕轴线39的旋转。
安装在后部隔板60中的密封件64和安装在前部隔板32中的密封件141，阻止位于隔板32、60之间的来自模块10的液体的通道。另一动态密封件144阻止在发动机曲轴146和模块10之间的污染物的通道。
模块10的组件安装并且装配在模块中。装配的模块然后可以安装在发动机输出12和扭矩转换器外壳48之间并连接至发动机输出12和扭矩转换器外壳48。
在操作中，当发动机输出12由发动机驱动时，扭矩从发动机通过转子毂40和挠性板42传递至扭矩转换器外壳48，条件是离合器22接合。转子34电机28通过管78、腿状部38、转子毂40和挠性板42不断可驱动地连接至扭矩转换器外壳48。因此，扭矩转换器外壳48可以单独由发动机驱动，条件是电机28关闭并且离合器22接合；扭矩转换器外壳48可以单独由电机驱动，条件是发动机关闭或发动机在操作中并且离合器脱离；并且，扭矩转换器外壳48可以由发动机和电机两者同时驱动。
在图2中，输入轴160通过飞轮66、挠性板162和花键18可驱动地连接至发动机输出12。穿过前端模块的正面安装的螺栓164，穿过输入轴160中的孔并且穿过转子毂40的腹板108插入。螺栓164旋进形成在耦合器轴166的正面上的螺纹孔中，因此提供转子毂40和耦合器轴166之间的轴向力的连续性。为了旋转，耦合器轴166通过花键连接167与转子毂40连接，花键连接167包括彼此接合的形成在转子毂40的内部径向表面上的轴花键齿和形成在耦合器轴166的外部径向表面上的轴花键齿。
挠性板168优选地通过焊接点170固定至扭矩转换器外壳48并且通过一系列铆钉172固定至耦合器轴166的凸缘174，因此将转子毂40固定至扭矩转换器外壳48。螺栓164将扭矩转换器49固定至前端模块10并且承载扭矩转换器49和模块10之间的轴向载荷。
在图3中，输入轴180通过飞轮66、挠性板162和花键18可驱动地连接至发动机输出12。挠性板168优选地通过焊接点170固定至扭矩转换器外壳48并且通过一系列铆钉172固定至耦合器轴182的凸缘174，因此将转子毂40固定至扭矩转换器外壳48。
为了旋转，耦合器轴182通过花键连接184连接至转子毂40，花键连接184包括彼此接合的形成在转子毂40的内部径向表面上的轴花键齿和形成在耦合器轴182的外部径向表面上的轴花键齿。
转子毂40由位于转子毂中的孔的径向内表面上的环形凹部形成。同样地，耦合器轴182由位于径向外表面上并且与转子毂40的凹部轴向地对准的环形凹部形成。C-夹子186共同接合转子毂40的凹部和耦合器轴182，因此将扭矩转换器49固定至前端模块10并且承载扭矩转换器49和模块10之间的载荷。
图4表明深冲挠性板(deep drawn flex plate)200，挠性板200从铆钉172径向向外并且轴向向后地延伸，挠性板200通过铆钉172固定至耦合器轴182。挠性板200的相对端通过一系列围绕轴线39隔开的螺栓202固定并且与形成在安装块206的孔中的内螺纹204接合，安装块206固定至扭矩转换器外壳48的外表面。
优选地，挠性板200围绕扭矩转换器49的前部延伸至扭矩转换器的后部在螺栓202和安装块206位于的地方。优选地，螺栓202在安装块206中径向地安装而没有增加后部隔板60和变速器54的前部表面之间的轴向尺寸。
可选地，挠性板200可以由在它的水平或径向长度部分中的孔形成。挠性板200的水平长度部分可以包含一系列从它的径向长度部分延伸的成角度地隔开的水平腿状部。
按照专利法规的规定，已经描述了优选的实施例。然而，应该注意的是，可选的实施例可以以不同于具体说明和描述的其它方式实践。
