本申请要求于2018年1月16日提交的美国发明申请No.15/872087的优先权，并要求于2017年2月1日提交的美国临时申请No.62/453031的权益，其全部内容通过引用如同被详细充分阐述一样并入本文。
技术领域
本公开涉及一种具有带压配式密封轴颈的输入轴的断开式动力输出单元。
背景技术
本部分提供与本公开相关的背景信息，其不一定是现有技术。
车辆具有带有断开式动力输出单元的全轮传动系越来越常见，该断开式动力输出单元允许车辆传动系以前轮驱动模式和全轮驱动模式操作。在一些情况下，断开式动力输出单元与前驱动桥共用共同的润滑流体。在要将断开式动力输出单元中的润滑流体与前驱动桥中的润滑流体隔离的情况下，若干动密封件可被包括在动力输出单元中以提供期望水平的密封。虽然该方案可能是有效的，但是我们注意，由于在额外的动密封件被包含到动力输出单元中时产生的拖曳力增加，多个动密封件的使用可能是不利的。
发明内容

在一种形式中，本教导提供一种断开式动力输出单元，该断开式动力输出单元包括壳体、齿轮轴、齿轮、齿轮轴轴承、输入轴、密封轴颈和动密封件。所述齿轮轴被接纳在所述壳体中且具有联轴器输出构件。所述齿轮被联接到所述齿轮轴以随其旋转。所述齿轮轴轴承支撑所述齿轮轴围绕一轴线相对于所述壳体旋转。所述输入轴能围绕所述轴线旋转，并被接纳穿过所述齿轮轴。所述输入轴具有花键段、联轴器输入构件和安装部，所述安装部沿着所述轴线被设置在所述花键段和所述联轴器输入构件之间。所述花键段被配置为驱动地联接到差速器箱上的配合花键段。所述联轴器输入构件被配置为驱动地联接到所述联轴器输出构件以允许旋转动力从所述输入轴传送到所述齿轮轴。所述安装部具有外表面。所述密封轴颈被联接到所述安装部以随所述输入轴旋转。所述密封轴颈具有输入轴孔和圆筒形延伸的密封表面。所述输入轴孔具有接合到所述外表面的内直径表面。所述动密封件被安装到所述壳体，并密封地接合所述圆筒形延伸的密封表面。所述动密封件沿着所述轴线被设置在所述齿轮轴轴承的与所述齿轮相对的一侧。
进一步的适用领域由本文提供的描述将变得显而易见。该概述中的描述和具体示例仅用于例示的目的，并不旨在限制本公开的范围。
附图说明
本文描述的附图仅用于所选实施例而不是所有可能实施方式的例示目的，并且不旨在限制本公开的范围。
图1是根据本公开的教导构造的示例性动力输出单元的一部分的剖视图；以及
图2是图1的一放大部分，其更详细示出密封轴颈。
在附图的若干视图中，相应的附图标记表示相应的部分。
具体实施方式
参见附图的图1，示出根据本公开的教导构造的示例性断开式动力输出单元(PTU)10的一部分。PTU10可以包括壳体12、输入轴14、齿轮轴16、齿轮18、联轴器20和密封轴颈22。联轴器20被配置用于将齿轮轴16选择性联接到输入轴14以围绕中心轴线A共同旋转，并且可以包括联轴器输入构件26和联轴器输出构件28。
壳体12可以限定腔30，输入轴14、齿轮轴16、齿轮18和联轴器20可以被接纳在腔30中。在提供的示例中，壳体12分别包括彼此联结以形成壳体12的第一壳体构件12a和第二壳体构件12b。应理解，垫片(未示出)可以被设置在第一壳体构件12a和第二壳体构件12b之间，并且垫片可以是组装到第一壳体构件12a和第二壳体构件12b的分立形成的部件，或可以由可固化密封材料制成，该可固化密封材料可以在第一壳体构件12a和第二壳体构件12b彼此组装之前被设置在第一壳体构件12a和第二壳体构件12b之间。
输入轴14可以被联接到旋转动力源，诸如为可以与用于驱动一对车辆前轮(未示出)的差速器总成(未示出)相关联的差速器箱(未示出)。输入轴14可以是中空结构，并且可以包括花键段40、联轴器输入构件26和安装部44，该安装部44可以沿着中心轴线A设置在花键段40和联轴器输入构件26之间。花键段40可以是可形成在输入轴14的第一轴向端上的外花键段。花键段40可以与形成在差速器箱上的相应(例如，内)花键段配合地接合。联轴器输入构件26可以被固定地联接到输入轴14的与花键段40相对的第二端。可被联接用于随差速器总成的输出部(未示出)旋转的中间传动轴48可以被接纳穿过输入轴14的中空内部50并且可以驱动地联接到前车轮中的相应一个。第一动密封件52可以被接纳在输入轴14的中空内部50中，并且可以被固定地且密封地接合到输入轴14。形成在动密封件52上的密封唇54可以被密封地接合到形成在中间传动轴48上的圆筒形密封表面56。
齿轮轴16可以是中空结构，其可以围绕输入轴14被同中心地接纳。第一圆锥滚子轴承60和第二圆锥滚子轴承62可以被安装到齿轮轴16和壳体12以支撑齿轮轴16围绕中心轴线A相对于壳体12旋转。在提供的示例中，第一圆锥滚子轴承60被设置在第一壳体构件12a中，第二圆锥滚子轴承62被设置在第二壳体构件12b中，从而齿轮18沿着轴线A被设置在第一圆锥滚子轴承60和第二圆锥滚子轴承62之间。可以包括滚针轴承64的一个或多个轴承可以在径向上被接纳在齿轮轴16与输入轴14之间以支撑输入轴14围绕中心轴线A旋转。联轴器输出构件28可以被联接到齿轮轴16用于共同旋转。
齿轮18可以是锥形齿圈(例如，螺旋锥齿轮或准双曲面齿轮)类型，其可以被用于在PTU10的齿轮轴16和输出小齿轮(未示出)之间的传动路径中。该构造的一示例在美国专利No.8,469,854中描绘。在提供的示例中，齿轮18是斜齿轮，其被配置为将旋转动力传送到配合斜齿轮(未示出)，该配合斜齿轮被设置用于围绕平行于中心轴线A的轴线(未示出)旋转。该构造的一示例在美国专利No.8,047,323中描绘。
联轴器20可以是可以被配置为在联轴器输入构件26和联轴器输出构件28之间选择性传送旋转动力的任何类型的装置。例如，联轴器20可以包括一种离合器，诸如多片式摩擦离合器或爪式离合器。然而，在提供的示例中，联轴器20包括具有内齿72的套筒70，该内齿72被配置为配合地接合形成在联轴器输入构件26上的外齿74和形成在联轴器输出构件28上的外齿76。在提供的示例中，第二圆锥滚子轴承62的内轴承座圈62a具有的内径被定尺寸为直径小于联轴器输入部分26的外径和联轴器输出部分28的外径。这样，输入轴14不能够完全滑动通过齿轮轴14。套筒70能沿着中心轴线A在第一位置(未示出)和第二位置(示出)之间轴向移动，在第一位置，套筒70上的内齿72从联轴器输入构件26上的外齿74或联轴器输出构件28上的外齿76脱离，在第二位置，套筒70上的内齿72与联轴器输入构件26上的外齿74和联轴器输出构件28上的外齿76接合。各种类型的致动器(未示出)可以被用于使套筒70在第一位置和第二位置之间平移，诸如具有离合器拨叉78的常规离合器拨叉致动器，该离合器拨叉78接合形成在套筒70中的周向槽80。
参见图1和图2，密封轴颈22可以是中空套筒状结构，其可以限定输入轴孔90、内密封孔92和外密封轴颈94。输入轴孔90可以限定直径表面100，该直径表面100被配置为利用诸如压配合的期望配合接合输入轴14上的安装部44的外表面102，从而密封轴颈22被联接到输入轴14以随其旋转且与中心轴线A精确地对准。内密封孔92可以限定周向延伸的密封表面106，该密封表面106可以被配置为密封地接合合适的静密封构件，诸如O形环108，该合适的静密封构件也可以密封地接合安装部44以阻止径向上在安装部44和密封轴颈22之间的流体连通。O形环108可以被接纳在形成于安装部44中的周向延伸的槽110中。内密封孔92可以包括截头圆锥形导入部分114，当密封轴颈22被推(在图中从左到右)在O形环108上且与安装部44上的外表面102接合时，该截头圆锥形导入部分114可以帮助压缩O形环108。外密封轴颈22可以限定圆筒形延伸的密封表面120，该圆筒形延伸的密封表面120被配置为密封地接合第二动密封件122，该第二动密封件122密封地接合到壳体12。第二动密封件122阻止径向上在密封轴颈22和壳体12之间的流体连通。在提供的示例中，在将第二动密封件122组装到壳体12之前，密封轴颈22被安装到输入轴14。相应地，导入倒角128被形成在密封轴颈22上并被配置为引导第二动密封件122且在第二动密封件122被推到密封轴颈22上时时第二动密封件122膨胀。导入倒角128可以在与第二圆锥滚子轴承62相对的一侧与圆筒形延伸的密封表面120相交。
圆筒形延伸的密封表面120被定尺寸为比花键段40上花键大在花键段的齿与第二动密封件52之间提供间隙的量。另外，圆筒形延伸的密封表面120的直径可以大于齿轮轴16的内径，从而密封轴颈22不能通过齿轮轴16。
第一动密封件52和第二动密封件122和O形环108将PTU10的壳体12中的润滑剂流体隔离到第一容纳部V1中，该第一容纳部V1与容纳用于差速器总成的润滑剂的第二容纳部V2分离且不同。在提供的示例中，第一容纳部V1和第二容纳部V2中的每个中的润滑剂是自动传动流体，但是应理解，替代地，不同润滑剂可以被容纳在第一容纳部V1和第二容纳部V2中。
实施例的前述描述已经被提供用于例示和说明的目的。其并非旨在穷举或限制本公开。特定实施例的单独的元件或特征通常不限于该特定实施例，而是在适用的情况下是可互换的并且可以在所选实施例中使用，即使未具体示出或描述。其也可以以许多方式变化。这样的变化不应被视为脱离本公开，并且所有这样的修改都旨在被包括在本公开的范围内。
