Description

多流道叶片泵
技术领域
本发明涉及一种多流道叶片泵。
叶片泵经常例如在汽车领域中使用，以便输送液压液体，尤其油。这种泵例如能够用作为动力转向泵或变速箱泵。
背景技术
这种叶片泵由DE 1 553 283 A中已知并且在距转子的轴线的最小距离的部位和距转子的轴线的最大距离的部位之间具有液压连接。
US 9,366,251 B2涉及一种多流道叶片泵。所述多流道叶片泵通常对称地构造，换言之，分别具有吸入区域和排出区域的多个泵围绕转子轴线设置。因此，所述泵的液压力和机械力能够相互平衡，并且至少在理论上不会产生作用到转子、还有其轴、还有周围的冲程环上的横向力。然而，在实践中，因生产所引起的公差使得所提到的构件及其几何形状不是对称的。这在运行时产生不对称的压力从而产生不对称的力。在所输送的油中的气泡或者对吸入区域的不平衡供油具有类似的作用。由于在力方面的这种不平衡，产生提高的噪音生成和磨损。迄今为止，这通过压力出口处相对窄的公差和/或缺口来抵抗，以便保持压力波动低。
发明内容
在此背景下，本发明的目的是实现一种多流道叶片泵，所述多流道叶片泵在噪音生成和/或磨损方面得到改进。
该目的通过在权利要求1中所描述的多流道叶片泵实现。
因此，该多流道叶片泵的特征在于，沿着转子的旋转方向的至少两个部位彼此液压地连接，在所述部位，在运行时基本上存在相同压力并且所述部位与入口和出口间间隔开。换言之，根据本发明的措施不同于在多流道或多冲程叶片泵中将多个入口和出口彼此连接的常用措施。更确切地说，根据本发明，将叶片泵内的区域彼此液压地连接，所述区域至少理论上具有相同的室压并且与入口和出口间隔开。由此，关于无论什么原因所引起的压力的不平衡都能够至少部分地得到补偿和平衡，使得以有利的方式减少噪音生成和磨损。
如接下来更详细地阐述，这通过相对低成本的措施是可行的。在这种情况下，在根据本发明的泵中设有的流道的数量是任意的，尤其地，能够是双流道、三流道、四流道或多流道叶片泵。在双流道、四流道或其他偶数流道叶片泵中，在对角线上相对置的室连接，而在三流道或五流道泵中，例如是以120°或72°并且在每种情况下在环周方向上均匀地彼此间隔开的室。
优选地，液压连接以在转子中和/或冲程环中和/或至少一个侧板中的开口的形式，尤其钻孔和/或槽的形式构成。特别地，能够在冲程环中铣削适合的槽，所述槽通过侧板金属地密封。此外，能够在侧板中构成开口，例如以钻孔的方式或通过增材制造法构成。相同的生产方法适用于在转子中构成开口以建立根据本发明的液压连接。这尤其能够在所有室之间构成，在所述室中，在运行时在理论上存在相同的压力，或者这能够通过连接这些室中的仅一些室来构成。在转子中构成开口等时产生如下优点：始终存在根据本发明的连接，而在冲程环或侧板上构成开口等时在泵的叶片经过设为用于液压连接的开口时连接中断。然而，这预期不会显著损害根据本发明的效果。
如果至少两个开口或槽距转子轴线的距离相同，那么能够特别广泛地利用根据本发明的效果。由此补充性地简化制造。
对于至少一个径向伸展的钻孔或槽和/或轴向开口，尤其当其直线地构成时，预期具有特别好的功能性和可制造性。
在其他应用情况中，能够以有利的方式通过尤其在冲程环中伸展的、至少部分地在环周方向上构成的连接来避免转子和侧板的削弱。
在这种情况下，如果至少一个连接围绕螺栓构成，那么所述优选的措施不产生提高的空间需求。
此外，对于根据本发明的泵的操作和组装，当其具有封闭侧板的盖和/或基本上罐形的壳体时提供优点。
对于至少在特定应用情况下构成形成根据本发明的连接的相对复杂的轮廓，增材制造方法也发挥了其优点。
附图说明
下面根据示例地在附图中示出的实施方式详细阐述本发明。附图示出：
图1示出根据本发明的泵的第一实施方式的液压原理简图；
图2示出根据本发明的泵的第二实施方式的横剖视图，
图3示出类似于第一实施例的根据本发明的泵的纵剖视图，
图4示出根据本发明的泵的第三实施方式的横剖视图，和
图5示出根据本发明的泵的第四实施方式的横剖视图。
具体实施方式
如从图1中可看到，在所示情况中双流道叶片泵10输送出自储液器12的液压液体。出于该目的，构成到相应吸入或入口区域16的两条管线14，并且以类似方式从相应的出口区域20延伸出彼此连接的两条管线18。
下面参考图2详细阐述叶片泵10的构造。然而，在图1中可看到，与入口16和出口20间隔开并且由于泵的双流道构成在对角线上相对置的区域或室借助于所示出的连接26彼此液压连接。出于该目的，在所示情况下，在侧板(40，参见图3)中构成开口28。旋转方向通过转子区域的箭头表示。
在图2中，这与图1的情况相反。在图2中，示出三流道叶片泵10，所述三流道叶片泵以已知方式具有转子30，所述转子具有切口32，叶片34在径向方向上分别可移动地容纳在所述切口中。根据三流道的构成，图2的实施方式具有三个入口16和三个出口20。所述入口和出口以已知方式在冲程环36中构成。根据在图1中示出的实施方式，与入口16和出口18间隔开的并且理论上存在相同压力的部位设有开口28，以便将所述部位液压地彼此连接。根据在图2中示出的叶片泵的三流道的构成，所述开口28彼此间隔开120°。此外可以看到优选的措施，根据所述措施，开口距转子轴线的距离相同。
如在图3中可看到，在侧板40之一中在图1中示意性表示的连接26以径向伸展的槽的形式构成并且将这两个开口28彼此连接。设有槽的侧板40用盖42封闭，并且盖42与这两个侧板40、转子30和冲程环36一起容纳在基本上罐形的壳体44中。
尽管这对于图2的三流道泵并未示出，但是根据本发明的连接也能够在转子30中以径向连接的形式或者在冲程环36中以在环周方向上伸展的连接的形式在三个室之间构成，如接下来对于双流道叶片泵所描述和在图4和图5中所示。
在图4中示出类似于图1的实施方式的叶片泵10，然而其中连接26构成用于在转子30中并且尤其也在其轴38中的上述的压力平衡。有利地，连接26构成为贯通的钻孔。为了在所有室的区域中实现完全的压力平衡，必须对于每个室对重复所述连接。
最后，在图5中可见另一实施方式，其中连接26在冲程环36中构成。如在图5中可看到，连接26在长的伸展上与冲程环36的外轮廓同心地构成并且借助于短的径向连接与泵的相应的室连接。在图5的左下方区域中可看到，连接26能够构成为围绕螺栓，所述螺栓作为圆形可见。
