Description

变量泵
技术领域
本发明涉及一种变量泵，具有用于供给和导出由变量泵输送的体积流的两个接头。此外，本发明涉及一种用于运行这类变量泵的方法
背景技术
从德国公开文献DE 199 30 648 A1已知一种电动液压的压力供给装置，其具有转速可调节的驱动电动机和变量泵、具有连接管路和负载接头，所述变量泵的排量能通过调节元件改变。
发明内容
本发明的任务是，简化可彼此独立地调节的体积流的提供。
在一种具有用于供给和导出由变量泵输送的体积流的两个接头的变量泵中，该任务由此解决：所述变量泵具有附加的接头，用于提供附加的体积流。由此以简单的方式实现具有不同的交替的体积流要求的两个液压负载的供给。液压负载例如涉及双离合器的子离合器。优选地，变量泵持续地以驱动方式与驱动设备连接，例如与内燃机式的驱动设备连接。在所述接头和所述附加的接头上所提供的体积流能有利地彼此分开地调节。
所述变量泵的一优选实施例的特征在于，所述变量泵能通过可彼此独立地调节的物理信号这样调节，使得在总共三个接头中的两个接头上的体积流能彼此独立地调节。所述接头中的一个接头涉及储备部接头，通过该储备部接头来抽吸要输送的液压介质。液压介质涉及例如液压油，所述液压油也被简称为油。两个另外的接头涉及变量泵的输入部或输出部。所述调节可以二维或三维地进行。
所述变量泵的另一优选实施例的特征在于，所述变量泵能通过可彼此独立地调节的物理信号这样调节，使得在总共三个接头中的两个接头上的体积流关于其流动方向能反转。流动方向的反转能尤其有利地在变量泵的输送方向的旋转方向不反转的情况下进行。调节信号的形式依赖于变量泵的类型或者说结构形式。
所述变量泵的另一优选实施例的特征在于，变量泵被实施为叶片泵或实施为径向活塞泵。在叶片泵的情况下和在径向活塞泵的情况下，优选地通过对着在泵壳体上的轮廓移动转子轴线来进行所述调节。对此，不同的移动方向确定各个泵输出部的体积流。
所述变量泵的另一优选实施例的特征在于，所述变量泵实施为轴向活塞泵。在轴向活塞泵的情况下，优选地由摆动板或摆动盘的倾斜产生体积流的调节，所述摆动板或摆动盘的倾斜引起泵活塞的轴向运动。对此，两个倾斜方向对在所述接头和所述附加的接头上所提供的体积流产生影响。
在一种用于运转前面说明的变量泵的方法中，替代地或者附加地，上述任务通过如下方式解决，在两个接头上分别提供体积流。这两个体积流能彼此分开地并且彼此独立地调节。能彼此独立地调整的这两个体积流可用于例如操纵双离合器。
所述方法的一个优选实施例的特征在于，在所述两个接头上所提供的体积流通过能独立地调节的物理信号彼此独立地调节。对此，调节信号的形式依赖于所使用的变量泵的类型。
所述方法的另一优选实施例的特征在于，在所述两个接头上所提供的体积流中至少一个体积流关于其流动方向反转。特别有利地，流动方向的反转在变量泵的转动方向不反转的情况下实现。
所述方法的另一优选实施例的特征在于，在所述两个接头上所提供的体积流汇聚成第三体积流。由此能进一步提高根据本发明的变量泵的功能性。
附图说明
从以下的说明得出本发明的另外的优点、特征和细节，在所述说明中参照附图详细地说明不同的实施例。附图示出了：
图1示出了根据第一实施例的变量泵的强烈简化的示图；
图2示出了与图1中的类似的示图，具有附加地示出的叶片；
图3示出了图2的变量泵，具有说明变量泵的运转的线和箭头；
图4示出了实施为轴向活塞泵的变量泵的立体图；
图5以不同的视角示出了图4的变量泵，和
图6示出了实施为径向活塞泵的变量泵的简化的示图。
具体实施方式
在图1至3中简化地示出具有壳体3的变量泵1。在壳体3中能转动地驱动转子5。在图1中，通过在转子5的中心的双箭头表明：转子5能在壳体3中运动，以调节变量泵1的输送体积或排量。通过线14至17在图1中表明调节方向，转子5能沿着所述调节方向在壳体3中运动。
变量泵1在壳体3上具有储备部接头10、接头11和附加的接头12。储备部接头10实现来自液压介质储备部(未示出)的液压介质的供给。
两个接头11和12有利地能彼此分开地调节。接头11例如与双离合器的第一子离合器的从动缸连接。然后，接头12有利地与双离合器的第二子离合器的从动缸连接。
所示出的接头10至12代表下述区域，在所述区域中，在壳体3上设置接头10至12。对此，接头10至12可布置在壳体3的壳面中。但是，接头10至12也可布置在壳体3的端面或者说端侧中。
在图2中可见，转子具有狭槽，用于能径向运动地布置总共八个叶片20狭槽。叶片20以其径向内部的端部布置在转子狭槽中。叶片20以其径向外部的端部贴靠在壳体3的内部轮廓上。
在图3中通过箭头19表明，转子5在顺时针方向上被驱动。在运转时，转子5与叶片20在壳体3中转动。通过转子5相对于壳体3的移动实现在输送运转时由变量泵1提供的体积流的调节。
在图1和2中，通过在转子5的中心的双箭头表明的移动能从外部在转子5上或者在壳体3上发起。对于旋转驱动的转子5可为有意义的是，用于调节由变量泵1提供的体积流的相对运动所需的移动在壳体3上实现。
转子5的驱动能例如通过与机动车驱动系的固定耦合实现。尽管用于调节体积流的移动不但能通过壳体3而且能通过转子5实现，但是以下根据转子5的移动来解释所述调节。
在图3中通过虚线21和22表示运动轴线，转子5能沿着所述运动轴线运动，用于调节在接头11和12上所提供的体积流。通过箭头23和24表明用于第一负载的泵方向指示器，所述第一负载例如是双离合器的第一子离合器。对此，虚线21示出了用于第一负载的中性线。由箭头25和26表示用于第二负载的泵方向指示器，所述第二负载例如是双离合器的第二子离合器。对此，虚线22表示用于第二负载的中性线。
如果转子5沿着虚线21移动，则第一负载的体积流保持等于零。同样，当转子5沿着虚线22移动时，第二负载的体积流保持等于零。
如果转子5如在图3中所示出的恰好位于中心，则该转子布置在这两个中性线21，22上。那么，由变量泵1所输送的体积流或者说在接头11和12上所提供的体积流独立于转子5的转速地等于零。
如果转子5从中性线21向左上方运动，则在接头11上向变量泵的方向抽吸液压介质或者流体，如通过运动箭头23所表明的。同样，在转动方向相同的情况下，在转子5向右下方运动时，流体或者液压介质在接头11上从变量泵压出，如通过运动箭头24表明的。
如果转子5从中性线22向右上方运动，则在接头12上向变量泵的方向抽吸流体，如通过运动箭头25所示出的。同样，在转动方向相同的情况下，在转子5向左下方运动时，流体在接头12上从变量泵压出，如由运动箭头26表明的。
在图4中以不同的视图立体地示出变量泵31。变量泵31实施为轴向活塞泵，并且能与以上所说明的变量泵1相类似的方式调节。
轴向活塞泵31包括具有盘34的壳体33。旋转器35相应于转子(在图1中的5)并且能被旋转地驱动。在旋转器35中，活塞36以能在轴向方向上来回运动的方式被导向。
活塞36通过滑座37支撑在摆动盘38上。在摆动盘38上设置有象征如下轴线的杠杆39，摆动盘38能围绕所述轴线摆动以便调节变量泵31的输送体积或者排量。
在盘34中设置有储备部接头40。此外，在盘34中设置有接头41和附加的接头42。
与之前所说明的变量泵1相比较，代替移动而通过摆动盘38的倾斜来调节变量泵31的、在接头41和42上所提供的体积流。在变量泵31运转时，旋转器35相对于具有接头40至42的盘34转动。对此，旋转器35同样相对于摆动盘38转动，其中，旋转的旋转器35携动活塞36。
旋转器35的驱动未示出并且能以不同的方式实现。旋转器35的驱动能例如通过穿过摆动盘38或穿过盘34延伸的轴实现。替代地，活塞35可直接通过构造在旋转器35本身上的齿部被驱动。
摆动盘38的倾斜能三维地调节。在调节变量泵31时的控制类似于叶片泵1的之前所说明的调节进行。与叶片泵1不同地，在轴向活塞泵31的情况下，不是偏移而是倾斜。
变量泵31的调节或设置借助分开的机构实现，该机构的附加在这里仅仅示意性地以杠杆39的形式示出。在图4和5中所示出的变量泵31包括在旋转器35中的三个活塞36。但是，不同于所示出的，在旋转器35中优选大于三个活塞36、例如五和六个活塞36以能沿轴向方向来回运动的方式被导向。
在图5中从略改变的视角示出了轴向活塞泵31，其具有取下的盘34。因为盘34包含接头40至42，所以盘34也被称作接头盘。如在图5中示例性地示出的，摆动盘38的支承部45通过球几何形状实现。
在图6中简化地示出实施为径向活塞泵的变量泵51。径向活塞泵51包括壳体53，在该壳体中，转子55在顺时针方向上能旋转地被驱动，如通过在转子55中心的箭头表明。在转子55中，在径向外部总共八个活塞56能来回运动地被导向。
径向地指向的活塞56分别以其径向内端部布置在转子55中。活塞56以其各自径向外端部，必要时在其间连接有滑座的情况下，贴靠壳体53的内部轮廓上。壳体53以与在图1至3中所示出的叶片泵1的情况类似的方式，包括储备部接头60、接头61和附加的接头62。
在径向活塞泵51的运转中，活塞56被径向向内压。类似于在图1至3中所示出的叶片泵1，在接头61和62上所提供的体积流的调节通过在壳体53和转子55之间的平移实现。
