[0001]本专利申请要求2008年4月4日提交的美国临时专利申请No.61/042,382的优先权及其所有权益，并且将其全部内容作为参考并入本文。
技术领域
[0002]本发明涉及一种用于在混合动力变速器中冷却电动机的系统和方法。
背景技术
[0003]用于车辆的混合动力变速器通常包括多个离合器和一对用于向车辆传动系统输送机械动力的电动机。为了正确地运转，变速器通常需要增压流体(例如，常规变速器油)的供给。该增压流体可以用于如冷却、润滑以及有时用于转矩传递装置的操作等功能。变速器油系统的润滑和冷却能力影响变速器的可靠性和耐用性。另外，多级变速器需要增压流体以用于转矩传递机构的受控接合和分离，该转矩传递机构操作以在内部齿轮布置中建立速比。
[0004]通常，增压流体经由第一电动液压回路中的阀和通道从泵流到离合器以操纵该离合器。流体从变速器内部排入变速器内的油槽中，在这里流体被再次使用。混合动力变速器中的电动机可以将电力转换成机械动力来操作传动装置。在变速器的操作期间，电动机会发热，因而需要对电动机的冷却。为了冷却电动机，采用第二电动液压回路来移动流体从而冷却电动机。
发明内容
[0005]一种向混合动力变速器的壳体供给流体的方法，包括升高整个系统的管路压力以引起通过控制系统的流体渗漏。渗漏的流体通过至少一个回填通道被引到该壳体。渗漏的流体被引导在该壳体内的至少一个电动机上经过，以冷却该至少一个电动机。被引导在至少一个电动机上经过的流体被收集，以在该壳体内形成排出压力。
[0006]一种用于向混合动力变速器供给流体的控制系统，包括构造成调节流到混合动力变速器的流体流量的调整阀。供给管路被可操作地连接至调整阀，并且构造成在混合动力变速器与调整阀之间输送流体。回填通道被可操作地连接至调整阀，并且构造成从调整阀向混合动力变速器供给渗漏的流体。旁通孔可操作地使供给管路与回填通道互相连接，并且构造成向该混合动力变速器供给额外流体。
[0007]混合动力变速器包括壳体。至少一个电动机和至少一个离合器被布置在该壳体内。控制系统与壳体流体连通，并且包括至少一个构造成调节流到该壳体的流体流量的阀。供给管路可操作地连接该阀和壳体，以在该壳体与阀之间输送流体。回填通道可操作地连接该阀和壳体，以在该阀与壳体之间输送流体。旁通孔可操作地使该供给管路与回填通道互相连接。旁通孔构造成向该壳体供给额外流体。
[0008]通过利用来自调整阀和换档阀的渗漏流体来实现电动机冷却和离合器回填。渗漏的流体通常是倒回变速器油槽并且被浪费掉。通过捕获并且将渗漏的流体重新引向电动机的电动机绕组，就以最有效的方式既实现了电动机冷却也实现了离合器回填。如果没有这种配置，那么就必须增加专用管路来提供电动机的冷却，且阀体渗漏始终会连续地浪费到变速器油槽中。通过将这些管路合并为一个，增加了整个系统的效率，对汽车的燃料经济性有着直接的、积极的影响。
[0009]根据下面结合附图对实施本发明的最佳模式所作的详细描述，本发明的上述特征和优点及其它特征和优点将会变得更加明显。
附图说明
[0010]现在参照作为示例性实施例的附图，其中，相同的部件用相同的附图标记标示：
[0011]图1是描述了与混合动力变速器一起使用的电动液压控制系统的示意性图示；
[0012]图2是图1的电动液压控制系统和混合动力变速器的局部示意图，其示出了用于向混合动力变速器内的电动机供给冷却流以冷却该电动机的流动通路；以及
[0013]图3是图1的电动液压控制系统的局部示意图，其示出了用于经由调整阀回填离合器以从该离合器清除空气的流动通路。
具体实施方式
[0014]参照附图，其中，相同的附图标记代表相同的部件，图1示出了带有混合动力变速器12的电动液压控制系统10。混合动力变速器12可包括带有四个离合器C1、C2、C3和C4的壳体13以及布置在壳体13内的两个电动机A和B。
[0015]控制系统10可包括四个调整阀T1、T2、T3和T4以及两个换档阀X和Y。该调整阀T1、T2、T3和T4以及该两个换档阀X和Y各自均包括限定有多个端口16的阀体14。阀构件18可滑动地布置在阀体14内，处于受冲击和不受冲击的位置之间。调整阀T1、T2、T3和T4以及两个换档阀X和Y的阀体14经由供给管路20互相连接的网络与变速器12的离合器C1、C2、C3和C4流体连通，用于使液压流体、润滑油等等移动通过控制系统10和变速器12以控制离合器C1、C2、C3和C4。供给管路20连接至各个端口16，以提供阀体14内的流体连通。
[0016]另外，控制系统10可包括多个螺线管S1、S2、S3、S4、S5和S6用于控制调整阀T1、T2、T3和T4以及两个换档阀X和Y。这些螺线管S1、S2、S3、S4、S5和S6构造成使每个螺线管S1、S2、S3、S4、S5和S6专用于相应的调整阀T1、T2、T3和T4或换档阀X和Y，用于在受冲击位置与不受冲击位置之间移动调整阀T1、T2、T3和T4或换档阀X和Y，以调节进入和排出相应的调整阀T1、T2、T3和T4或换档阀X和Y的流体，从而控制壳体13内的离合器C1、C2、C3和C4。
[0017]流体在壳体13与控制系统之间经由供给管路20进行循环。流体从变速器12被引导或流动通过供给管路20，并且从供给管路20经由调整阀T1、T2、T3和T4以及换档阀X和Y回到壳体13内的离合器C1、C2、C3和C4。流体可以经由泵22而通过供给管路20、调整阀T1、T2、T3和T4、换档阀X和Y、变速器12等等。泵22可以是离合器泵、辅助泵等。在操作期间，当流体移动通过调整阀T1、T2、T3和T4和/或换档阀X和Y时，少量流体会在阀体14与阀构件18之间渗漏。整个系统的管路压力可以被升高以引起通过调整阀T1、T2、T3和T4以及换档阀X和Y的流体渗漏。多个回填通道24从端口16延伸，并且使变速器12内的调整阀T1、T2、T3和T4以及换档阀X和Y在其阀体14内互相连接。回填通道24通常延伸至壳体13的顶面15，在每个电动机A和B之上经过。当流体从调整阀T1、T2、T3和T4和/或换档阀X和Y渗漏时，这些回填通道24捕获该流体，并且在这些回填通道24内的流体在通常较低压力下流向变速器12的壳体13的顶面15。渗漏的流体被引导着在壳体13内的电动机A和B之上流过以冷却电动机A和B。重力使流体从壳体13的顶面15向下流过电动机A和B。被引导着流过电动机A和B的流体被收集在壳体13中，并且最终流体会朝着壳体的顶面15向上充填以充填离合器活塞腔17。离合器活塞腔17位于邻近离合器C1、C2、C3和C4中各自之一。流入壳体13的流体产生排出压力。壳体13内的排出压力迫使流体向上朝着壳体13的顶面15并进入离合器活塞腔17，并且在较低压力下从离合器活塞腔17进入离合器C1、C2、C3和C4中以清除离合器C1、C2、C3和C4中被截留的任何空气。
[0018]为了向壳体13提供额外流体，在供给管路20与回填通道24之间布置至少一个旁通孔19。旁通孔确保了，即使通过调整阀T1、T2、T3和T4和/或换档阀X和Y不能获得足够的渗漏，仍然有适当量的流体经过回填通道24流向壳体13的顶面15。因此，旁通孔19在允许足够量的流体从其中流动的同时，限制了流体在供给管路20与回填通道24之间的流量。流体被引导着，从供给管路20经由旁通孔19流向回填通道24。
[0019]如上所述，来自调整阀T1、T2、T3和T4和/或换档阀X和Y内的渗漏，经由回填通道24被引向电动机A和B以冷却电动机A和B的定子绕组26。随着通过变速器12的操作而使控制系统10内的温度升高时，电动机A和B的温度也升高。因此，随着电动机A和B的温度升高，需要更多的流体来实现电动机A和B所需的冷却。然而，随着控制系统10内的温度升高，流体的渗漏也增大，导致需要更多的流体来满足冷却电动机A和B的需要。如果，由于某种原因，没有足够的流体可用于冷却电动机A和B的定子绕组26，阀构件18就可在阀体14内移动以将流体直接引入回填通道24从而增补渗漏的流体。
[0020]电动机A和B优选为布置在变速器12的壳体13的顶面15的附近。参照图2，电动机A和B放置在变速器12的顶面15附近使得被喷溅的流体在电动机A和B的定子绕组26上流过。从那里，重力可促使流体在壳体13中向下流，并且进入布置在变速器12底部的变速器油槽28或其它类似装置中，以在控制系统10和变速器12中再次使用。
[0021]现在参照图3，示出了一个调整阀T1。回填通道24之一使调整阀T1与相应的离合器C1互相连接。回填通道24内的回填压力足以预装填或“回填”离合器C1，也就是，在离合器C1处于未接合状态时清除可能被容纳在离合器C1内的空气。应该认识到，尽管图3只示出了用于经由调整阀T1从离合器C1清除空气的回填配置，但是在其它每个调整阀T2、T3和T4之间都有类似的布置，以从相应的离合器C2、C3和C4中清除任何空气。
[0022]尽管已经详细描述了实施本发明的最佳方式，但熟悉本发明所涉及领域的技术人员将会认识到用于在所附权利要求范围内实践本发明的各种替换性设计和实施例。
