Description

具有制动系统的可断开传动系
技术领域
本公开涉及一种具有制动系统的可断开传动系。
背景技术
此部分提供涉及本公开的背景信息，其不必要为现有技术。
诸如跨界车的许多现代车辆可使用基于前轮驱动(FWD)结构的全轮驱动(AWD)驱动系。此可选性驱动系设置允许驱动转矩被选择性地和/或自动地从动力系传输至主(即，前)传动系和副(即，后)传动系，以当车辆在恶劣天气和非公路路况下运行时提供更好的牵引力。这种AWD车辆必需装配更加复杂的传动系，除了主传动系，其必须包括与副传动系关联的另外的元件，诸如动力输出单元和传动轴。
为了在没有驱动转矩传输至副传动系时使与被后驱动的副传动系关联的传动系损失(即，粘滞阻力、摩擦力、惯性和搅油)最小化，已知的是包含可断开系统，其被配置为从副传动系的剩余部分分离副传动系的元件，诸如例如后轮或者后差动器。我们已经发现由一些供应商提供的可断开系统的部分不能以相对快速的方式完全地断开，这样存在当可断开系统被操作以禁止旋转动力的传输时其将继续传输一些(相对小)量的旋转动力的情况。相应地，本领域中存在对于在AWD车辆中使用的改进的可断开传动线的需要。
发明内容
此部分提供本公开的大体概要，而不是其完全范围或者其全部特征的全面公开。
在一种形式中，本教导提供一种车辆传动系，其包括壳体、安装在该壳体中用于绕第一轴线旋转的输入轴、联接至该输入轴用于绕该第一轴线旋转的差速箱、被接收在该差速箱中的差速齿轮组、被接收在该壳体中并绕该第一轴线能旋转的第一齿轮、联轴器、制动元件和输出轴。该联轴器具有被联接至该输入轴用于随之旋转的第一联接部和被轴向滑动地但不可旋转地联接至该第一齿轮的第二联接部。该第二联接部沿该第一轴线在第一联接位置和第二联接位置之间能移动，在该第一联接位置旋转动力在该输入轴和该第一齿轮之间能传输，在该第二联接位置旋转动力在该输入轴和该第一齿轮之间不能传输。该制动元件被联接至该壳体并当该第二联接部在该第二联接位置时能接合至该第二联接部，以阻止该第二联接部相对于该壳体旋转。该输出轴被驱动地联接至该第一齿轮并绕不与该第一轴线平行的第二轴线能旋转。
其他应用领域将从这里提供的描述变得明显。在此概要中的描述和特定示例仅旨在例示的目的，并且不旨在限制本公开的范围。
附图说明
这里描述的附图仅用于例示所选实施例的目的，而不是所有可能的实施，其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车辆的示意图；和
图2是图1的车辆的一部分的截面图，其更详细地图示一部分动力输出单元。
在附图的几个视图中，对应的附图标记指示对应的部件。
具体实施方式
参考附图的图1，根据本公开的教导构造的示例车辆大体上由附图标记10指示。车辆10可具有动力系12和传动系统或者传动系14。动力系12可被常规地构造，并可包括动力源16和变速器18。动力源16可被配置为提供推进动力并可包括例如内燃机和/或电动马达。变速器18可从动力源16接收推进动力，并可将动力输出至传动系14。变速器18可具有多个自动或者手动选择的齿轮比。
传动系14可包括前桥组件20、动力输出单元(PTU)22、传动轴24和后桥组件26。变速器18的输出可被驱动地联接至前桥组件20的输入30。前桥组件20可包括前差速组件或者第一差速组件34，其可包括前差速箱或者第一差速箱36和前差速齿轮组或者第一差速齿轮组38。第一差速箱36绕第一旋转轴线40可旋转。在提供的示例中，第一差速组件34被配置为在全时基础上将旋转动力从第一差速箱36分配至一对前半轴或者第一半轴42，以驱动关联的一对前轮或者第一轮44。
参考图1和图2，PTU 22可包括壳体50、输入轴52、第一齿轮54、联轴器56、制动元件58和输出轴60。壳体50可被配置为容纳PTU 22的其他元件，并可选地被配置为容纳前桥组件20的全部或者一部分。对应地，将认识到壳体50可包括多个分离的壳体元件(未特别示出)，其可被组装在一起以形成壳体50。输入轴52可被固定地联接至第一差速箱36，用于绕第一旋转轴线40共同旋转。
第一齿轮54可绕第一旋转轴线40旋转。在提供的示例中，第一齿轮54为一种锥齿轮，诸如直齿锥齿轮、螺旋锥齿轮或者准双曲面齿轮，并被配置为与另一齿轮(即，固定地联接至输出轴60的小齿轮64)配合，以沿着大体上垂直的动力传输路径引导旋转动力。可替换地，第一齿轮54可为正齿轮或者斜齿轮(未示出)，其被配置为沿着使用具有平行旋转轴的一对或多对齿轮的传输路径传输旋转动力。此后者类型的PTU的示例在共同转让的U.S.专利No.8047323中示出，其公开通过参考合并，如同详细地完全展示于此。在提供的特定示例中，第一齿轮54被安装在空心阀芯66上，其由一对轴承68(图2)支撑以相对于壳体50旋转，该对轴承可包括一个或多个角球轴承和/或一个或多个滚锥轴承和/或四点角接触轴承。一个第一半轴42可被接收通过阀芯66和第一齿轮54。联轴器56可为能够被用于选择性地将旋转动力在输入轴52和第一轴承54之间传输的任何类型的设备，诸如摩擦离合器(未示出)或者齿圈(未示出)，其可沿第一旋转轴线40轴向滑动，以选择性地接合联接用于与输入轴52一起旋转的齿构件(未示出)。
特别参照图2，在提供的特定示例中，联轴器56为爪形离合器或者犬齿形离合器。联轴器56一般地可包括第一联接部70(例如，第一棘爪)和第二联接部72(例如，第二棘爪)，第一联接部70可被联接至输入轴52用于共同旋转，第二联接部72可被非旋转地联接至第一齿轮54用于共同旋转、但是沿第一旋转轴线40相对于第一齿轮54轴向可滑动。在提供的示例中，空心阀芯66的悬臂部66a沿着第一轴线从第一齿轮54在朝向第一联接部70的方向上延伸，并包括多个公齿或者外花键齿76，其被形成在第二联接部72中的多个母齿或者内花键齿78接合。任意类型的驱动器可用于将第二联接部72在第一联接位置和第二联接位置之间转变，在第一联接位置，第二联接部72被驱动地联接至第一联接部70以允许旋转动力在输入轴52和第一齿轮54之间传输，在第二联接位置，第二联接部72从第一联接部70脱离，从而禁止旋转动力在输入轴52和第一齿轮54之间传输。在提供的示例中，第二联接部72限定被配置为接收传统的离合器拨叉82(图1)的离合器拨叉槽80，离合器拨叉82可通过任何合适的机构，诸如线性马达84(图1)而转变。
制动元件58可被非旋转地联接至壳体50，并且当第二联接部72从第一联接部70脱离并朝向第二联接位置移动时可接合至第二联接部72。在提供的示例中，制动元件58被安装至壳体50用于沿第一旋转轴线40滑动移动，并在沿第一旋转轴线40朝向第二联接部72的方向上被弹簧90偏压。可与壳体50一体地形成的第一止动元件84和制动元件58之间的接触可在沿第一旋转轴线40朝向第二联接部72的方向上限制制动元件58的移动，从而当第二联接部72在第一联接位置时制动元件58不能接合第二联接部72。和第二止动元件86之间的接触可将弹簧90的一端限制在与制动元件58相对的一侧上，第二止动元件86可包括被接收在壳体50中的槽88中的卡环。
第二联接部72可包括第一摩擦表面100，其在制动元件58和第二联接部72相互接合时接合形成在制动元件58上的第二摩擦表面102。在所示的示例中，第一摩擦表面100和第二摩擦表面102具有截头圆锥的形状，但是将意识到，第一摩擦表面100和第二摩擦表面102可被不同地成形。另外，第一摩擦表面100和/或第二摩擦表面102可被配置具有期望的一组摩擦特性，以在制动元件58和第二联接部72相互接合时控制第一摩擦表面100和第二摩擦表面102之间的摩擦、润滑和磨损。在这点上，第一摩擦表面100和/或第二摩擦表面102的形成材料(包括基底材料和任意随后的涂层)、第一摩擦表面100和第二摩擦表面102的热处理和表面加工和/或第一摩擦表面100和第二摩擦表面102中的一个或两个所使用的摩擦材料或层可用于提供期望水平的摩擦、耐磨性和润滑控制。
返回至图1，输出轴60绕可大体上垂直于第一旋转轴线40的第二旋转轴线(与图1中示意性示出的输出轴60一致)旋转。输出轴60可被驱动地联接至传动轴24的第一端。
传动轴24被配置为在PTU 22的输出轴60和与后桥组件26关联的输入小齿轮120之间传输旋转动力。后桥组件26可进一步包括环形齿轮122、后差速组件或第二差速组件124、一对后半轴或第二半轴126和断开系统128。环形齿轮122可与输入小齿轮120啮合。第二差速组件124可包括第二差速箱130和一对差速输出构件138。每个差速输出构件138被配置为驱动关联的一个第二半轴126。断开系统128可包括一个或多个联轴器，其可操作以选择性禁止车辆推进动力从传动轴24向至少一个第二半轴126传输。在提供的示例中，断开系统128包括摩擦离合器134，其用于选择性地将环形齿轮122联接至第二差速箱130，但是将意识到断开系统128可被不同地配置。例如，摩擦离合器134可被布置在传动轴24和输入小齿轮120之间，或者在一个差速输出构件138和其关联的第二半轴126之间。替代地，断开系统128可另外地或者替代地使用另一类联轴器，诸如犬齿形离合器或者爪形离合器。作为另一个替代，断开系统128可为第二差速组件124的一体化部件(例如，第二差速组件124可包括一对摩擦离合器，每个摩擦离合器被配置为控制旋转动力向关联的一个第二半轴126的传输)。
有时在车辆10的运行期间，当PTU 22中的联轴器56脱离接合(即，第二联接部72在第二联接位置)并且断开系统128被操作使得车辆推进动力不能从传动轴24向至少一个第二半轴126传输时，一些旋转动力(即，力矩)仍然可通过断开系统128被传输，即使量将不足以推动车辆10。在这种情况下，车辆10的一对后轮144提供旋转动力，其以将一般地导致传动轴24的对应旋转的量被传输。因为制动元件58被接合至第二联接部72，但是在这种情况下传动轴24的旋转被阻止。在这点上，第二联接部72上的第一摩擦表面100和制动元件58上的第二摩擦表面102(图2)之间的摩擦阻止空心阀芯66和第一齿轮54的旋转，从而阻止PTU22的输出轴60和旋转地联接至输出轴60的传动轴24的旋转。
为了图示和说明的目的，已经提供实施例的以上说明。其不旨在详尽或者限制本公开。特定实施例的单独的元件或特征一般地不限于该特定实施例，而是可应用的话，即使没有特殊示出或描述，其可相互交换并可被用于选择的实施例中。相同的也可以许多方式变化。这种变化不被视为对本公开的背离，全部这种改进旨在包括在本公开的范围内。
