本案为2012年1月31日递交的、第13/362,018号未决美国申请的部分继续申请案。
背景技术
本发明涉及一种用于混合动力电动车辆的动力传动系统，特别是涉及一种位于发动机输出与变速器输入之间并固定在二者上的动力传动系统模块。
混合动力电动车辆(HEV)同时具有内燃发动机和电机，它们交替地或联合起来用于推进车辆。混合动力车辆中使用各种不同的动力传动系统，例如平行配置，其中发动机通过分离离合器连接至马达，马达驱动自动动力变速器的液力变矩器输入。变速器具有连接至差速器的输出，差速器耦接至车辆的两个驱动轮。
工业中需要提供一种混合动力电动动力传动系统，其包括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数个发动机中的一个的输出与数个变速器中的一个的输入之间，并固定在二者上。装配的动力传动系统可以接着应用在各种车辆中。模块应当包括液压驱动的分离离合器，电机和发动机与电机之间通向变速器输入的合适的动力路径。优选地，该模块为从变速器的液压系统至离合器、平衡坝和电机的液压连通作准备。该模块必须提供含有传送至模块的液压流体的油底壳以及用于流体不断返回变速器的油底壳的路径，以使变速器泵被可靠地不断供应有流体。
模块化混合动力变速器(MHT)包括模块，其在用螺栓固定至发动机与变速器之间的外壳中含有分离离合器和电机。该外壳被供应来自变速器管路压力回路和润滑油回路的机油，由于该外壳是MHT的一部分且被用螺栓固定在变速器的前面，因此有时称其为前模块(FM)。该机油将排至FM的底部然后返回变速器。低温、等级和高流速可能将导致机油充满回流通路。

根据本发明的一个实施例，其中来自模块的液压流体返回外壳。
通风系统将两个通风管路连接在一起，以确保前模块与变速器外壳之间没有差压，并且提供从模块至变速器的适当的变速器流体的回流。
根据以下具体实施方式、权利要求和附图，优选实施例的适用范围将变得显而易见。应当理解，尽管给出了本发明优选的实施例，说明书和具体示例仅通过说明的方式给出。对于描述的实施例和示例的各种变化和改进对于本领域技术人员来说将变得显而易见。
附图说明
通过参考以下说明和附图将更容易理解本发明，附图中：
图1A和1B包含动力传动系统模块的侧横截面视图，其示出了至发动机输出的前连接以及至变速器液力变矩器输入的后连接；并且
图2为图1的动力传动系统的侧横截面视图，其示出了具有用螺栓固定的、集成的柔性板的液力变矩器；并且
图3为图1的动力传动系统的侧横截面视图，其示出了具有弹性耦接集成的柔性板的液力变矩器。
具体实施方式
图1A和1B示出了用于混合动力电动车辆的动力传动系统的前模块10，其包括：具有旋转输出12的发动机；固定至发动机输出12的扭转减振器14；通过花键18固定至减振器14的输出20的输入轴16；支承在通过花键26固定至输入轴16的离合器轮毂24上的分离离合器22；电机28，其包括用螺栓连接至前隔板32的定子30以及由第一支腿36以及第二支腿38支承用于绕着轴线39旋转的转子34；优选通过焊接固定至支腿38的转子轮毂40；以及柔性板42，其一端通过花键连接44或通过螺栓110固定转子轮毂40并且其相对端通过螺栓46固定至封装液动力液力变矩器49的液力变矩器壳48。电机28可以是电动马达或电动马达发电机。
由前隔板32和后隔板60以及多个液压密封件封装的模块10含有湿式体，该湿式体被供应自动变速器流体，用于驱动分离离合器22、润滑并冷却离合器22和电机28。类似地，由外壳58封装的自动变速器54含有湿式体，该湿式体含有自动变速器流体，用于驱动变速器的离合器和制动器、润滑并冷却位于外壳58中的离合器和制动器、轴承、轴、齿轮等。液压流体从变速器58被供应至模块10并且从该模块返回外壳58内的变速器油底壳。
适用于动力传动系统中的液力变矩器在2011年12月14日递交、第13/325,101号美国专利申请的图4a、4b、5、12和15中公开并参照上述附图得到说明，该专利申请的全部公开以参考引用的方式结合于此。
液力变矩器49包括位于壳48内并固定在其上的叶片叶轮；由叶轮液动力驱动并通过花键50固定至自动变速器54的输入轴52的叶片涡轮；以及位于涡轮与定子之间并固定至定子轴56的叶片定子轮，其保持在变速器壳58上不旋转。
通过螺栓62固定至变速器壳58的后隔板60在其径向内表面安装有液压密封件64，液压密封件64接触转子轮毂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运转发动机启动齿轮70，其通过焊接至启动齿轮和飞轮的盘72被固定。
轴承74支承第一支腿36用于在前隔板32上旋转。轴承76支承第二支腿38用于在转子轮毂40上旋转。与轴线39对齐并支承转子34用于绕着轴线旋转的管78固定至第一支腿36和第二支腿38。分别处于管78的前后端的边缘80、82可以径向向外卷，以将转子34固定至管78并避免转子34相对于管的轴向位移。管78的内表面形成有轴向花键81，其通过支腿36、38以及分离离合器22的交替盘83被接合。离合器22的摩擦盘84通过在离合器轮毂24的径向外表面上形成的轴向花键被固定。
用于驱动离合器22的液压伺服系统包括活塞86、平衡坝88、回位弹簧90以及用于将驱动压力传递至活塞86右边的压力控制体92和活塞左边的压力平衡体94的液压管路。当驱动压力和液压流体供应至体92时，通过使用密封件151和152，活塞86在由后支腿38构成的汽缸中向左移动，从而引起离合器22接合并通过减振器14、输入轴16、离合器轮毂24和离合器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88和回位弹簧90被支承在转子轮毂40上，因此活塞86、平衡坝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，扭矩路径包括后支腿38、转子轮毂40、柔性板42、液力变矩器壳48、液力变矩器叶轮与涡轮之间的液动力驱动连接，该连接通过花键50连接至变速器输入轴52。
分解器100——一种用于测量旋转程度的高精度类型的旋转电力变压器——通过螺栓102固定至前隔板32、支承在前隔板32和第一支腿上并轴向位于前隔板32与后隔板60之间。
在柔性板42与转子轮毂40之间产生旋转驱动连接的花键44的齿被固定在一起，使得当扭矩在柔性板与转子轮毂之间传递时不产生空隙。柔性板42形成有厚壁的部分104，该厚壁的部分104具有止于网状物108的螺纹孔106。柔性板42上的外部花键齿通过螺栓110被迫轴向与转子轮毂40上的内部花键齿啮合，其在转子轮毂40的右端接合螺纹孔。花键连接44上啮合的花键齿当移除螺栓110时被解离，并将较大的螺栓穿过孔106，使得螺栓接触网状物，从而迫使柔性板轴向向右。
转子轮毂40形成有多个轴向引导的液压通路120以及侧向引导的通路120、122、124、126、128、129，上述通路运载液压流体和压力从变速器54的液压系统至模块10。通路122、124、126、128、129运载包括至位于活塞86的右边的离合器22的伺服系统的控制体92、至平衡坝88与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的表面的液压流体和压力，其中转子34和定子30的表面由流体冷却。后隔板60形成有通路128，该通路128与VFS 130液压地连通。
后隔板60支承油底壳132，该油底壳132含有从变速器54的液压系统供应至模块10的流体。变速器54包括油底壳136，其含有由变速器泵134供应至变速器液压系统的液压流体，流体和控制压力从变速器液压系统被供应至模块10、液力变矩器49、变速器离合器和制动器、轴承、轴、齿轮等。
安装在前隔板32中的轴承140以及安装在转子轮毂40中的轴承142支承轴16绕着轴线39旋转。前隔板32还将定子30支承在其相对于转子34的合适的轴向和径向位置。安装在后隔板60与转子轮毂40之间的轴承76以及轴承142支承转子轮毂40绕着轴线39旋转。前和后隔板32、60一起支承转子34绕着轴线39旋转，这是由于安装在隔板32中的轴承74和安装在隔板60中的轴承76。
安装在后隔板60中的密封件64以及安装在前隔板32中的密封件141阻拦来自位于隔板32、60之间的模块10的流体的通路。另一动态密封件144阻拦发动机舱146与模块10之间的污染物的通路。
模块10的组件安装并装配在该模块中。装配的模块接着可以被安装在发动机输出12与液力变矩器壳48之间并连接至二者。
在操作中，当发动机输出12被发动机驱动时，扭矩由发动机经过转子轮毂40和柔性板42传递至液力变矩器壳48，前提是离合器22被接合。通过管78、支腿38、转子轮毂40和柔性板42，电机28的转子34被不断可驱动地连接至液力变矩器壳48。因此，液力变矩器壳48可以：单独由发动机驱动，前提是电机28关闭且离合器22被接合；单独由电机驱动，前提是发动机关闭或发动机正在运行且离合器被解离；以及由发动机和电机同时驱动。
在图2中，输入轴160通过飞轮66、减振器162和花键18可驱动地连接至发动机输出12。通过前模块的前侧安装的螺栓164被插入输入轴160中的膛孔以及转子轮毂40的网状物108。螺栓164被压入耦合器轴166的前侧形成的螺纹孔，从而在转子轮毂40与耦合器轴166之间提供轴向力连续性。耦合器轴166通过花键连接167与转子轮毂40连接，用于旋转，花键连接167包括互相啮合的在转子轮毂40的内径向表面上形成的轴向花键齿以及在耦合器轴166的外径向表面上形成的轴向花键齿。
柔性板168优选通过焊接170固定至液力变矩器壳48，并通过一系列铆钉172固定至耦合器轴166的凸缘174，从而将转子轮毂40固定至液力变矩器壳48。螺栓164将液力变矩器49固定至前模块10并通过使用推力轴承99在液力变矩器49与模块10之间运载轴向负载。
在图3中，输入轴180通过飞轮66、减振器162和花键18被可驱动地连接至发动机输出12。柔性板168优选通过焊接170固定至液力变矩器壳48并通过一系列铆钉172固定至耦合器轴182的凸缘174，从而将转子轮毂40固定至液力变矩器壳48。
耦合器轴182通过花键连接184被连接至转子轮毂40，用于旋转，其中花键连接184包括互相啮合的在转子轮毂40的内径向表面上形成的轴向花键齿和在耦合器轴182的外径向表面上形成的轴向花键齿。
转子轮毂40形成有位于转子轮毂中的膛孔的径向内表面的环形槽。类似地，耦合轴182形成有位于径向外表面且与转子轮毂40的槽轴向对齐的环形槽。C形夹186将转子轮毂40与耦合器轴182的槽互相接合起来，从而将液力变矩器49固定至前模块10并通过使用推力轴承99在液力变矩器49与模块10之间运载轴向负载。
使自动变速器54和前模块10通风至空气会导致变速器外壳58与前模块之间的压差，这是由于通风行为和性能造成的。如图2所示，为了避免这种可能性，第一通风管路200和第二通风管路202在三通接头204被连接，使得管路200、202互相连通并与环境空气连通，其中第一通风管路200通过前隔板32与前模块10的内部连通，第二通风管路202通过变速器外壳58与变速器54的内部连通。该通风布置气动地连接两个通风管路200、202，从而防止模块10与变速器外壳54之间的差压的发展，并且确保适当的回流用于由模块至变速器的变速器流体。
尽管已经描述了管状通风管路200、202的使用，但是模块10的内部、变速器外壳58的内部和环境空气之间所需的气动连通也可以在钟形外壳58中使用铸件或钻道来完成，其中钟形外壳58含有液力变矩器49和它的壳48。
根据专利法规的规定，已经描述了优选的实施例。然而，应当注意到，除了特别说明和描述的之外还可以实施另外的实施例。
