Description

增压器正时齿轮油泵
技术领域
本发明涉及用于正排量/容积式增压器的油泵，并更具体地涉及由增压器的正时齿轮（timinggear）提供的油泵。
背景技术
使用正排量气泵来给内燃机增压和为其它目的提供空气在本领域是已知的。当用作汽车增压器时，这种泵可以包括壳体，该壳体具有转子腔以及空气进入和排出通道。在增压器的腔中，一对相互啮合的或交错的转子旋转，以便泵送通过进入通道吸入的空气和随后通过排出通道排出空气。
增压器的内部部件如齿轮和轴承通常通过容纳在增压器内的特殊配方的工作流体提供润滑。通常，这种工作流体通过飞溅润滑输送到增压器的内部部件。
发明内容
本发明的一个实施例针对具有壳体的正排量泵。壳体包括用于允许较低压力入口空气进入的入口和用于排出较高压力出口空气的出口。泵还包括相互啮合的第一和第二鼓风机转子，所述转子旋转地布置在壳体中并设置成将较低压力入口空气转变成较高压力出口空气。泵还包括相互啮合的第一和第二正时齿轮，所述第一和第二正时齿轮分别相对于第一和第二转子固定，用于防止第一和第二转子之间接触，并被充分封装以产生润滑流体流。此外，泵包括输入驱动装置，输入驱动装置适于被正转矩以与内燃机的速度成比例的速度旋转地驱动。输入驱动装置设置成驱动第一和第二正时齿轮。
本发明的另一个实施例针对具有增压器——例如上述正排量泵——的内燃机。
从下面结合附图对实施本发明的最佳方式的详细描述，可以清楚地发现本发明的上述特征和优点以及它特征和优点。

具体实施方式
参见附图，其中，在几个图中，同样的附图标记对应于同样的或类似的部件，图1示出内燃机2，该内燃机2具有多个燃烧室4和曲轴皮带轮6。皮带轮6由内燃机2的曲轴（未示出）驱动，如本领域技术人员所理解的。总体上由附图标记10指示的压缩机或增压器组件示出为连接到内燃机2上。增压器组件10适于与内燃机2一起使用，并且是可操作的以增加内燃机2的容积效率。增压器组件10由内燃机2通过皮带8驱动。尽管本文的增压器可以是具有相互啮合的叶状转子的罗茨式增压器或具有相互啮合的叶状转子的螺旋式增压器，但在图2中示出罗茨式增压器。
增压器组件10在图2-3中详细示出。增压器组件10包括输入驱动装置11，该输入驱动装置11适于被正转矩以与内燃机的速度成比例的速度围绕旋转轴线X旋转地驱动。输入驱动装置11包括壳体12。壳体12典型地由铸造金属如铝、镁等形成。壳体12包括第一端14和相对的第二端16。第一端14包括用于输入轴壳体18的连接装置。具有第一端22和第二端24的输入轴20在内部设置到输入轴壳体18上。输入轴20通过轴承26和28旋转地支承在输入轴壳体18中。在输入轴壳体18中安装有旋转密封件29。密封件29安装成使得，密封件的内径与输入轴20的外径接触并防止外来材料从增压器组件10的外部进入壳体18和防止任何流体沿相反方向流出。
输入轴20的第一端22固定地接纳皮带轮30，该皮带轮30通过皮带8连接到曲轴皮带轮6上，从而增压器组件10由内燃机2驱动（如图1中所示）。输入轴20的第二端24保持凸缘32，该凸缘32用于与联接件34接合，该联接件34继而通过柱37与第一或主动正时齿轮36接合。主动正时齿轮36连续地与第二或从动正时齿轮38啮合。因此，输入驱动装置11直接驱动第一和第二正时齿轮36和38。正时齿轮36和38分别相对于第一和第二转子轴40和42固定。转子轴40旋转地安装在第一前轴承44和第一后轴承46上，转子轴42类似地安装在第二前轴承48和第二后轴承50上。第一和第二前轴承44和48安装并支承在支承板52中，第一和第二后轴承46和50安装并支承在壳体12中。
转子轴40和42分别固定到第一和第二交错并连续啮合的转子54和56上，以便与所述转子54和56一体地旋转。因此，相互啮合的正时齿轮36和38分别相对于转子54和56固定，尤其是以便防止在增压器组件10工作期间转子之间接触。转子54和56安装成在形成于壳体12内的转子腔58内旋转，并设置成将较低压力入口空气转变成较高压力出口空气。输入轴壳体18直接安装到支承板52上，因此在支承板和输入轴壳体之间形成油槽或齿轮箱60。正时齿轮36和38因此设置成在油槽60的范围内旋转。第一旋转密封件62和第二旋转密封件64安装在支承板52上。旋转密封件62和64的内径分别与转子轴40和42的外径接触，以防止润滑流体从油槽60泄漏到转子腔58中。
壳体12的第二端16包括低压空气入口66，该低压空气入口66设置成允许典型地环境空气到达转子54和56。较低压力空气典型地通过节气门体部组件（未示出）进入入口66，该节气门体部组件根据内燃机速度和载荷控制进入空气的量。如本领域技术人员已知的，较低压力入口空气被第一和第二转子54和56压缩。因此，较低压力入口空气被第一和第二转子54和56转变成较高压力出口空气。然后较高压力出口空气被排出，并通过空气出口68（在图3中示出）输送到燃烧室4（在图1中示出）。较高压力出口空气与内燃机内部的燃料给合，用于随后的燃烧。增压器组件10在出口表面70处安装在内燃机2上。典型地，增压器组件10通过合适的紧固装置如多个螺钉（未示出）连接到内燃机2上，以有助于压缩空气与燃烧室4最直接连通。
正时齿轮36和38被支承板52和盖件53充分地封装，以在增压器组件10运行期间经由齿轮齿39产生加压润滑流体的持续流。由正时齿轮36和38所提供的润滑流体流并因此产生的流体压力与输入驱动装置11的旋转速度成比例，输入驱动装置11的旋转速度由内燃机的速度通过皮带8控制（在图1中示出）。加压润滑流体流用来冷却和润滑增压器的内部部件，以便抵销由增压器在载荷下所产生的热量。
由正时齿轮36和38所产生的润滑流体流可以容纳在油槽60内或从外部源——即，在增压器组件10外部的源——通过专用的外部通道（未示出）供应。这种外部供应润滑流体到正时齿轮36和38将附加地允许增压器组件10相对于地面处于基本上竖直的取向。由于流体供应给正时齿轮36和38不受重力的影响，所以当旋转轴线X设置成基本上与重力方向平行时，第一和第二旋转密封件62和64没有浸没在流体中的危险。因此，在车辆中，增压器组件10甚至可以以输入驱动装置相对于地面朝上或朝下的方式安装在内燃机上。因此，外部供应低压流体给正时齿轮36和38为增压器组件10的封装提供了额外的灵活性。
参见图4，示出了增压器组件10A，除了不仅具有正时齿轮36和38而且还具有相互啮合的旋转件36A和38A之外，该增压器组件10A在所有方面都与图3中所示的增压器组件10相同。在操作中，当与正时齿轮36和38一起使用时，相互啮合的旋转件36A和38A帮助正时齿轮36和38提供加压润滑流体流。当与正时齿轮36和38一起使用时，相互啮合的旋转件36A和38A无助于产生流体流。相互啮合的旋转件36A和38A被支承板52A和盖板53充分地封装（在图2和3中示出），以在增压器组件10运行期间经由齿39A产生润滑流体的持续流。由正时齿轮36和38提供的润滑流体流并因此产生的流体压力与输入驱动装置11的旋转速度成比例，输入驱动装置11的旋转速度由内燃机的速度控制。
如图3中所示，盖件53包括流体入口72和流体出口74，流体入口72用于从油槽60或从外部源引出低压流体，流体出口74用于将加压流体输送到可能需要它的地方。尽管图3的支承板52和盖件53示出为封装正时齿轮36和38，但流体流的产生也可以通过不使用单独的盖件53获得。通过正时齿轮36和38获得的加压润滑流体流也可以通过构造输入轴壳体18和支承板52的在正时齿轮的端面附近与正时齿轮邻接的表面获得，例如通过精密机加工。具有流体入口72和流体出口74的盖件53类似地也可使用在增压器组件10A（在图4中示出）中。然而，如同正时齿轮36和38一样，通过正时齿轮36A和38A获得的加压流体流可以通过使用正时齿轮、输入轴壳体18和支承板52A之间的紧密配合获得。
由正时齿轮36和38及相互啮合的旋转件36A和38A所产生的流体流可以用来比非加压的飞溅润滑更有效地润滑输入驱动装置11。被正时齿轮36和38加压的流体也可以连通到通常要求提供外部润滑供应的外部装置，例如图5中所示的涡轮增压器组件76。如图5所示，由正时齿轮36和38所产生的加压流体流经由油入口通道78输送到涡轮增压器组件76，并在离开涡轮增压器之后经由油返回通道80被带回油槽中。
参见图6，示出了增压器组件10B，除了用输入驱动装置11B代替输入驱动装置11之外，该增压器组件10B在所有方面都与图2所示的增压器组件10相同。输入驱动装置11B包括装置82，该装置82将皮带轮30连接到主动正时齿轮36上，使得它能够向转子54和56提供可选择的速度输入。因此，与图2的在结构上限于向转子提供不可选择的直接驱动输入的驱动输入装置11相比，输入驱动装置11B提供了对转子54和56的旋转速度的增强控制。输入驱动装置11B由电子控制单元（ECU）84控制。ECU84可以构造成独立单元，或者可以结合在内燃机控制器中。
装置82通过使用具有多个不同传动比的可切换的齿轮组实现可选择的多个速度。此外，装置82可以使用例如无级变速器（CVT）或电动变速器（EVT）的机构来在规定范围内连续改变输入速度，如本领域技术人员已知的。与不可选择的直接驱动的输入驱动装置11相比，本文所设想的可选择速度的输入驱动装置11B通常要求提高的润滑。然而，由正时齿轮36和38所供应的加压流体可以足够满足输入驱动装置11B的提高的润滑要求，且不需要额外供应的润滑。因此，输入驱动装置11B的特征在于没有由在增压器组件10B外部的源所提供的润滑。
尽管详细说明了用于实施本发明的最佳方式，但熟悉本发明所涉及的领域的人会意识到，用于实践本发明的各种可供选择的设计和实施例都在所附权利要求书的范围内。
