Description

滑摆泵
技术领域
本实用新型涉及一种滑摆泵(pendulum slider pump)，根据权利要求1的前序部分，其具有内转子，内转子通过摆杆与外转子连接。
背景技术
DE10334672B3公开了一种通用滑摆泵，在驱动轴上具有非常大的扭矩，通过偏心轨道运道实现活塞泵的传递动作。柱形工作室布置在单部件或多部件式的壳体中，在柱形工作室的侧面，设置有至少5个分散布置在周面上的窝槽，摆杆腹的头部布置在窝槽中。设置有摆杆槽的压力环转动地布置在偏心轮的底座上，其中在压力环的摆杆槽下面的足部区域，设置有同时朝向吸入舱和压力舱的通道流动开口。通过这种方式，简化了尤其是对工作室的进口和出口的控制。
DE19532703C1公开了另一种滑摆泵，其具有最小的惯性，该泵具有可转动的内转子和可拆卸地安装的外转子，通过摆杆，内转子与外转子共同转动。为了使偏心安装的外转子由内转子转动驱动，在一时间，仅一个摆杆与其驱动头、驱动脚和唯一的一个滑动侧边滑动接触。配合轮廓与摆杆的第二滑动侧边以不接触的方式导引入槽中。摆杆的驱动头的截面比驱动脚的截面小，结果是现在能够降低位于径向外侧的先前不利的高质量，由此同样可降低惯性。
但是，现有技术中已知的滑摆泵的缺点在于，利用这些泵，摆杆脚部空间不能填充或排空或者非常困难才能填充或排空，脚部空间即由两个槽壁、内转子的一个槽底和关联的摆杆脚部限定的空间。基于此，流体(尤其是油)在一定条件下积聚在摆杆脚部空间中，结果形成了动态滞止压力，动态滞止压力会以不可控制的方式改变或影响外转子相对于内转子的偏心度，因此，使得精确地控制滑摆泵的传递率是非常困难的。
实用新型内容
因此，本实用新型处理的是这样的问题，提出通用型滑摆泵的改进的或至少替换的实施方式，其不存在现有技术中的缺点。
根据本实用新型，该问题由独立权利要求的主题来解决。有利的实施方式是从属权利要求的主题。
本实用新型基于这样一种总体构思，在摆杆脚部空间和位于外侧的关联室之间设置连通通道，连通通道可靠地防止了在摆杆脚部空间中形成动态滞止压力，同时，连通通道被设计或布置成使得其不会负面地影响将摆杆导引入滑摆泵的内转子的关联径向槽中。这里，本实用新型的滑摆泵具有所述的内转子，其通过摆杆连接到外转子。摆杆以铰接方式安装在外转子上，同时以其摆杆脚部导引入内转子的径向槽中。外转子、内转子和两个在周向上相邻的摆杆相应限定出压力/吸入室(压力/吸入舱)，此外，摆杆脚部与两个槽壁和槽底一起限定出前述的摆杆脚部空间，根据本实用新型，摆杆脚部空间现在通过连通通道连接到位于外侧的室(例如，吸入室/压力室)，同时在槽底的区域通向摆杆脚部空间。通过本实用新型的连通通道的布置，能够实现将摆杆脚部空间中简单的填充或排空流体(例如，油)，结果能够可靠地避免过去在该区域出现的不期望的动态滞止压力生成。通过避免动态滞止压力，外转子相对于内转子的偏心率不会以不期望的方式偏离设定值，使得通过能够精确控制的偏心率，本实用新型的滑摆泵的传递量也可以精确地调整。对于现有技术中已知的常规滑摆泵，在摆杆脚部空间中产生动态滞止压力是因为，由于摆杆脚部空间中存在的流体的不可压缩性，使得阻碍了摆杆进入槽的进入运动，结果，外转子相对于内转子的偏心度的角度范围变大。这导致由外转子、内转子和两个在周向上相邻的摆杆所限定的腔的容量变化，同时降低了滑摆泵的传递率。同时，用来驱动滑摆泵的电动机需要克服动态滞止压力，结果增加了所需驱动功率。借助本实用新型设置的在槽底的区域通向摆杆脚部空间的连通通道，可以额外地确保摆杆脚部空间的优先彻底排空，因此，不会以任何方式对摆杆的进入运动产生阻碍。除此之外，连通通道在槽底通向摆杆脚部空间提供了非常大的优势，即用来导引相应摆杆的槽的槽壁不会受损，结果可以实现低摩擦和没有阻碍的导引。
在本实用新型的方案的另一有利改进中，为每个摆杆脚部空间设置连通通道，其在转动方向上布置在关联的摆杆的前面或后面。通过连通通道的不同布置，可以使泵的力条件适合于特定应用。相应地，通过布置在关联摆杆的前面，可以削弱限制的趋势，即削弱降低内转子偏心度的趋势。由此可以获得有利的运行状态，其特征在于稳定性非常好。根据应用，也可以想到尤其更简单的限定泵：其中，连通通道布置在关联的摆杆的后面，以便例如实现更简单地调整偏心度。
实际中，可以为每个摆杆脚部空间设置两个连通通道，它们在转动方向上设置在关联的摆杆的前面和后面。通过设置两个这种连通通道，可以实现尤其有效及简单地排空摆杆脚部空间，因为在摆杆进入槽的进入运动期间，摆杆脚部空间中存在的流体量可以通过两个连通通道排出。利用这种滑摆泵，此外，转动方向不会对相应摆杆脚部空间的填充或排空产生影响，因此，其可以独立于转动方向来操作。此外，由于该布置因而可实现泵中受力关系的中立行为。
在本实用新型的方案的另一有利实施方式中，所述至少一个连通通道设计为孔或槽，在该例子中，其由端面上的盖封闭。将连通通道设计为孔提供了非常大的优点，即可以简单且非常精确的方式将连通通道随后引入内转子。根据同样的方式，连通通道也可以形成为布置在相应内转子的端面上的槽，其通过对应的连通部分与相应摆杆脚部空间的槽底连通。在该例子中，所述槽形成在内转子中，所述连通通道通过用盖子覆盖该槽而形成。
可替换的，所述至少一个连通通道可以明显地被预成型，尤其通过烧结或通过铸造过程中的合适的铸造型芯来预成型。在后一种例子中，铸造型芯在铸造后被冲洗掉，由此仅留下连通通道。也可以想到利用烧结法制造内转子或连通通道。侵蚀法也原则上适合于制造连通通道。
根据本实用新型的方案的另一有利实施方式中，连通通道实施为直线形或曲线形的。直线形实施方式提供的优点在于，可以例如通过简单的钻孔来制造连通通道。可以考虑例如曲线形连通通道的设计特性，其可以通过侵蚀法制造，或通过在铸造期间插入合适的盐芯或沙芯制造。
本实用新型的其他重要特征和优点体现在从属权利要求、附图、附图的附图说明中。
应该理解的是，上述提及的和下面仍将要解释的特征不仅可用于描述的相应组合中，还可用于其他组合或单独使用，这并不脱离本实用新型的范围。
附图说明
本实用新型的优选实施例示出在附图中，并在下面的说明中进行更详细地解释。其中，相同的附图标记表示相同的、相似的或功能相同的部件。
此处在各情况下示意地示出了：
图1为本实用新型的滑摆泵的剖面图；
图2为具有曲线形连通通道的摆杆滑动泵的详细构造图；
图3为图2所示的摆杆滑动泵的构造图，但具有直线形连通通道。
具体实施方式
参考图1，本实用新型的滑摆泵1例如可以设计为机动车中的油泵，其包括内转子2，内转子2通过摆杆3与外转子4连接。这里，摆杆3以铰接方式安装在外转子4上，它们的摆杆脚部5导引入内转子2的径向槽6中。为了实现铰接安装，摆杆3包括摆杆头，摆杆头安装在外转子4上的对应接合窝中。外转子4、内转子2和两个在周向上相邻的摆杆3还限定出室7，根据转动位置，室7形成为吸入室或压力室。参考图2和图3的详细构造图，尤其从这些图明显的看出，摆杆脚部5与两个槽壁8、8’以及槽底9一起限定出摆杆脚部空间10，摆杆脚部空间10通过连通通道11(见图1-3)连接到关联的室7，其中，连通通道11在槽底9的区域通向摆杆脚部空间10。
在图1-3所示的滑摆泵1中，每个脚部空间10通过连通通道与关联的室7连接，其中，根据内转子2的转动方向，连通通道11布置在摆杆3的前面或后面。相反，参考图3，很明显，利用相同的布置，原则上可以为每个摆杆脚部空间10设置两个连通通道11，它们在转动方向上分别设置在关联的摆杆3的前面和后面。参照图3，两个连通通道11之一用实线表示，另一个用虚线表示。
利用本实用新型的连通通道11，可以实现摆杆脚部空间10的尤其简单且快速的填充或主要是排空，结果可以有效避免在摆杆脚部空间10内不期望的动态滞止压力的形成。要避免动态滞止压力的形成，这尤其是因为动态滞止压力使得相应摆杆3难以进入关联的槽6中或会阻碍相应摆杆3进入关联的槽6中的进入运动，由此会以不期望的方式影响外转子4相对内转子2的偏心度。在偏心度被改变或不期望地被影响的情况下，滑摆泵1的传递性能也会受到影响。通过在每个摆杆脚部空间10上设置至少一个连通通道11，可以可靠地避免该不期望的动态滞止压力的形成。通过在槽底9区域中为连通通道11设置开口，可以额外地实现彻底且简单地排空摆杆脚部空间10，除此之外，槽壁8、8’不会受到使得它们不再以期望方式对摆杆3进行导引的影响。此外，通过为每个摆杆脚部空间10设置两个连通通道11，可以甚至更快速地进行排空或填充操作，结果可以制造出尤其平滑运行的滑摆泵1。
纯理论上来说，连通通道11可以形成为槽，由未示出的端面盖封闭。可替换地，还可想到的是，连通通道11可以形成为孔，例如图3所示的。在该例子中，连通通道11实施为直线形的。可替换地，连通通道11也可以实施为曲线形的(参见图1和图2)，其中，在该例子中，连通通道11例如是通过侵蚀法制造的，或在铸造过程中通过插入适合的铸造型芯来制造。
通过本实用新型的为每个摆杆脚部空间10设置至少一个连通通道11，可以实现直接填充或排空摆杆脚部空间10，尤其是在为每个摆杆脚部空间10仅设置一个连通通道11时。通过本实用新型的连通通道11，还可以减小磨损的趋势，这是由于滑摆泵1不再需要克服摆杆脚部空间10中的高动态滞止压力。通过连通通道11通向相应槽6的底部(即槽底9的区域)，在内转子2上(即具体来说在槽壁8、8’上)不会产生摆杆3的摩擦区域的任何减小。
