Offenbarung der ErfindungDisclosure of the invention
Die vorliegende Erfindung betrifft eine Mehrkolbenpumpe nach dem Oberbegriff des Anspruchs 1.The The present invention relates to a multi-piston pump according to the preamble of claim 1.
Eine
derartige Mehrkolbenpumpe ist beispielsweise aus der
Vorteile der Erfindungadvantages the invention
Die erfindungsgemäße Mehrkolbenpumpe mit den Merkmalen des Patentanspruchs 1 weist demgegenüber den Vorteil auf, dass sie eine gleichmäßige umlaufende Belastung einer Antriebswelle und der die Antriebswelle lagernden Lager sicherstellt. Hierdurch können ferner Geräusche reduziert werden und insbesondere eine pulsationsfreie Förderung erreicht werden. Darüberhinaus kann die erfindungsgemäße Mehrkolbenpumpe einfacher und kostengünstiger bereitgestellt werden. Dies wird erfindungsgemäß dadurch erreicht, dass jede Kolbenpumpe einer ersten Pumpeneinheit parallel zu einer Kolbenpumpe einer zweiten Pumpeneinheit angeordnet ist. Somit wird sichergestellt, dass die Kolbenpumpen der ersten und zweiten Pumpeneinheit gleich angeordnet sind. Dadurch wird vermieden, dass durch unterschiedliche Anordnung der Kolbenpumpen ungleichförmige mechanische Kräfte auf die Antriebswelle und die Lager ausgeübt werden. Ferner ergeben sich durch die parallele Anordnung der Kolbenpumpen der ersten und zweiten Pumpeneinheit eine reduzierte Anzahl von Richtungen, von welchen gefertigt und montiert werden muss. Darüberhinaus kann die parallele Anordnung noch sicherstellen, dass Leitungslängen der Leitungen von und zur ersten Pumpeneinheit und Leitungslängen der Leitungen von und zur zweiten Pumpeneinheit gleich lang ausgebildet werden können. Dies hat den großen Vorteil, dass dadurch gleiche Ansprechzeiten von unterschiedlichen Bremskreisen erreicht werden können, die jeweils von der ersten und zweiten Pumpeneinheit versorgt werden. Dadurch können die Bremskreise beispielsweise direkt ohne Umwege mit einem Hochdruckschaltventil in jedem Bremskreis verbunden werden.The inventive multi-piston pump with the features of claim 1, in contrast, the Advantage on that they have a uniform circumferential load of one Drive shaft and the drive shaft bearing bearing ensures. This allows furthermore noises be reduced and in particular a pulsation-free promotion be achieved. Furthermore can the multi-piston pump according to the invention easier and cheaper to be provided. This is inventively achieved in that each Piston pump of a first pump unit parallel to a piston pump a second pump unit is arranged. This ensures that that the piston pumps of the first and second pump unit equal are arranged. This avoids that by different Arrangement of the piston pumps non-uniform mechanical forces the drive shaft and the bearings are exercised. Furthermore arise by the parallel arrangement of the piston pumps of the first and second Pump unit a reduced number of directions, of which must be manufactured and assembled. In addition, the parallel Make sure still that line lengths of the lines from and to the first pump unit and line lengths of the lines of and can be formed the same length for the second pump unit. This has the big one Advantage that thereby same response times of different Brake circuits can be achieved each supplied by the first and second pump units. Thereby can the brake circuits, for example, directly without detours with a high-pressure switching valve be connected in each brake circuit.
Die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Lösung.The under claims show further advantageous embodiments of the inventive solution.
Vorzugsweise umfassen die erste und die zweite Pumpeneinheit jeweils drei Kolbenpumpen. Die Kolbenpumpen sind vorzugsweise jeweils in einem Winkel von 120° am ersten und zweiten Excenter angeordnet.Preferably The first and second pump units each comprise three piston pumps. The Piston pumps are preferably each at an angle of 120 ° on the first and second eccentric arranged.
Ein weiterer Vorteil liegt darin, dass die beiden Bremskreise nun auch hydraulisch symmetrisch ausgeführt werden können, was die Herstellung weiter vereinfacht. Da die erfindungsgemäßen Mehrkolbenpumpen vorzugsweise in Fahrzeugen eingesetzt werden und daher Massenprodukte sind, ergeben sich durch die erfindungsgemäßen Parallelanordnungen der Kolbenpumpen große Einsparungspotentiale.One Another advantage is that the two brake circuits now hydraulically symmetrical can be which further simplifies the production. Since the multi-piston pumps according to the invention preferably used in vehicles and therefore mass-produced are obtained by the parallel arrangements of the invention Large piston pumps Savings potential.
Weiter bevorzugt sind der erste Excenter und der zweite Excenter in einem Winkel zueinander verdreht angeordnet. Der Winkel beträgt dabei besonders bevorzugt ca. 150°.Further Preferably, the first eccentric and the second eccentric are in one Angle arranged twisted each other. The angle is thereby more preferably about 150 °.
Um eine besonders kompakte Anordnung zu erhalten und möglichst kurze Leitungswege im Gehäuse der Mehrkolbenpumpe zu realisieren, sind die Kolbenpumpen der ersten Pumpeneinheit in einer ersten Hälfte der Mehrkolbenpumpe angeordnet und die Kolbenpumpen der zweiten Pumpeneinheit in einer zweiten Hälfte der Mehrkolbenpumpe angeordnet.Around to obtain a particularly compact arrangement and possible short cable paths in the housing To realize the multi-piston pump, the piston pumps are the first Pump unit in a first half arranged the multi-piston pump and the piston pumps of the second Pump unit in a second half arranged the multi-piston pump.
Die Kolbenpumpen einer Pumpeneinheit sind besonders bevorzugt in einer Hälfte in einem Winkelbereich von ca. 120° angeordnet. Dies stellt einen sehr kompakten Aufbau bereit.The Piston pumps of a pump unit are particularly preferred in one half arranged in an angular range of about 120 °. This constitutes one very compact construction ready.
