Description
Die Erfindung geht aus von einer Radialkolbenpumpe zur Kraftstoffhochdruckerzeugung bei Kraftstoffeinspritzsystemen von Brennkraftmaschinen, insbesondere bei einem Common-Rail-Einspritzsystem, mit einer in einem Pumpengehäuse gelagerten Antriebswelle mit einem exzentrischen Wellenabschnitt, auf welchem eine Laufrolle gelagert ist, und mit vorzugsweise mehreren bezüglich der Antriebswelle radial in einem jeweiligen Zylinder angeordneten Kolben, an deren der Laufrolle zugewandten Enden jeweils eine Kolbenfußplatte angeordnet ist, welche die Umfangsfläche der Laufrolle kontaktiert, gemäß der Gattung von Anspruch 1.The Invention is based on a radial piston pump for fuel high pressure generation in fuel injection systems of internal combustion engines, in particular in a common rail injection system, with one in a pump housing mounted drive shaft with an eccentric shaft section, on which a roller is mounted, and preferably with several in terms of the drive shaft arranged radially in a respective cylinder Piston, at whose ends facing the roller respectively a Kolbenfußplatte is arranged, which contacts the peripheral surface of the roller, according to the genus of claim 1.
Eine
solche Radialkolbenpumpe ist beispielsweise aus der
Der vorliegenden Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Radialkolbenpumpe der eingangs erwähnten Art derart weiter zu entwickeln, dass ihre Zuverlässigkeit erhöht wird.Of the The present invention is based on the object, a Radial piston pump of the type mentioned above so on develop that their reliability elevated becomes.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.According to the invention this Problem solved by the characterizing features of claim 1.
Indem erstmalig zumindest zumindest die die Umfangsfläche der Laufrolle kontaktierende Fläche der Kolbenfußplatte aus einem verschleißfesten Material, nämlich aus Hartmetall, aus einem keramischen Werkstoff, aus einem gegossen karbidischen Werkstoff oder aus Cermet besteht, wird die Verschleißneigung der Kolbenfußplatten-Laufrollen-Paarung entscheidend reduziert. Die genannten Werkstoffe weisen gegenüber den bisher verwendeten Stahlwerkstoffen einen signifikant höheren E-Modul auf, was in geringeren Verformungen bei Belastung und folglich auch in einer gleichmäßigeren Flächenpressung ohne nennenswerte Spannungsspitzen resultiert. Beim Einsatz von keramischen Werkstoffen spielt vor allem deren geringeres Gewicht eine vorteilhafte Rolle, da die Kolbenfußplatte zusammen mit dem Kolben in hoher Frequenz beschleunigt und verzögert wird und folglich die Massenträgheit wesentlich herabgesetzt wird.while For the first time at least at least contacting the peripheral surface of the roller surface the piston foot plate made of a wear-resistant Material, namely made of tungsten carbide, of a ceramic material, of a cast carbide material or consists of cermet, the tendency to wear the piston footplate roller mating decisively reduced. The materials mentioned have the opposite previously used steel materials a significantly higher modulus of elasticity on, resulting in less deformation under load and consequently also in a more even surface pressure without significant voltage spikes results. When using Above all, their lower weight plays a role in ceramic materials advantageous role, since the Kolbenfußplatte together with the piston accelerated and decelerated in high frequency and consequently the inertia is significantly reduced.
Dabei kann die Kolbenfußplatte vollständig aus dem verschleißfesten Material hergestellt sein oder sie besteht wie bisher aus Einsatzstahl oder Vergütungsstahl und trägt auf ihrer zur Laufrolle weisenden Fläche wenigstens einen Einsatz aus dem verschleißfesten Material. Die Verwendung von Einsätzen bringt den Vorteil eines modularen Aufbaus, d.h. dass eine standardisierte Kolbenfußplatte mit Einsätzen aus verschiedenem Material versehen werden kann und somit eine Vielzahl von Varianten erzeugbar ist.there can the piston foot plate Completed from the wear-resistant Be made of material or it is still made of case-hardened steel or tempered steel and carries at least one insert on its surface facing the roller from the wear-resistant Material. The use of inserts brings the advantage of a Modular construction, i. that a standardized piston footplate with inserts can be provided from different material and thus a variety of variants can be generated.
Bei Verwendung eines keramischen Werkstoffs enthält dieser vorzugsweise Siliziumnitrit Si3N4 und weist eine Rauhtiefe Rz zwischen 0,15 μm und 0,5 μm auf. Hartmetalle können beispielsweise aus G20, GC37 oder GC20 bestehen und eine Rauhtiefe Rz zwischen 0,3 μm und 1,0 μm aufweisen, während der gegossen karbidische Werkstoff durch ein Schalenhartgussmaterial, insbesondere durch GGH oder SoGGH gebildet wird, welches eine Rauhtiefe Rz zwischen 0,5 μm und 2,0 μm aufweist.When using a ceramic material, this preferably contains silicon nitrite Si 3 N 4 and has a surface roughness R z of between 0.15 μm and 0.5 μm. Hard metals may for example consist of G20, GC37 or GC20 and have a roughness R z between 0.3 microns and 1.0 microns, while the cast carbide material is formed by a shell hard casting material, in particular by GGH or SoGGH, which has a roughness R z between 0.5 μm and 2.0 μm.
Besonders bevorzugt weist die Kolbenfußplatte auf ihrer der Laufrolle zugewandten Fläche wenigstens zwei sich kreuzende Nuten auf. Dadurch wird der Überdeckungsbereich von Kolbenfußscheibe und Laufrolle ohne Schmierstoffzuführung eliminiert. In den als Stauspalten wirkenden Nuten kann sich Kraftstoff ansammeln, welcher aufgrund der Gleitgeschwindigkeit zwischen der Laufrolle und der Kolbenfußplatte die Ausbildung eines hydrodynamischen Gleitfilms fördert, wodurch der Verschleiß an den Gleitflächen weiter reduziert wird.Especially Preferably, the Kolbenfußplatte on its surface facing the roller at least two intersecting Grooves on. This will make the coverage area of piston foot disc and eliminates roller without lubricant supply. In the as Stauspalten acting grooves can accumulate fuel, which due to the sliding speed between the roller and the piston footplate promotes the formation of a hydrodynamic sliding film, thereby the wear on the sliding surfaces is further reduced.
