Description
Die Erfindung betrifft eine Radialkolbenpumpe, insbesondere eine Radialkolbenhochdruckpumpe, für ein Kraftstoffeinspritzsystem nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a radial piston pump, in particular a radial piston high pressure pump, for a Fuel injection system according to the preamble of the claim 1.

Nachteilig an solchen Schmiernuten ist, dass die Querschnittsfläche der Schmiernuten relativ groß im Verhältnis zur Querschnittsfläche der gesamten Abflachung ist. Hierdurch nimmt die tragende Fläche der Abflachung ab, wodurch wiederum ein erhöhter Verschleiß auftritt. Zudem kann das Öl leicht aus den Schmiernuten herausgedrückt werden, so dass bei hohen Drehzahlen keine ausreichende Schmierung der Gleitflächen gewährleistet ist. Nicht zuletzt müssen die Schmiernuten in einem aufwendigen Fertigungsverfahren in die entsprechende Fläche eingebracht werden.adversely At such lubrication grooves is that the cross-sectional area of the Lubricating grooves relatively large in the relationship to the cross-sectional area the entire flattening is. As a result, the bearing surface of the Flattening off, which in turn occurs an increased wear. In addition, the oil can be easily pushed out of the lubrication grooves, so that at high Speeds do not ensure adequate lubrication of the sliding surfaces is. Last but not least the lubrication in an elaborate manufacturing process in the corresponding area be introduced.
Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, eine gegenüber dem Stand der Technik verbesserte Radialkolbenpumpe bereitzustellen, die eine sichere und dauerhafte Funktion auch bei hohen Pumpendrücken und Drehzahlen gewährleistet und darüber hinaus einen einfachen Aufbau aufweist.Of these, Based on the object of the present invention, one with respect to the State of the art to provide improved radial piston pump, the safe and permanent function even at high pump pressures and Guaranteed speeds and above has a simple structure.
Diese Aufgabe wird durch die Merkmale des unabhängigen Patentanspruch 1 gelöst.These The object is solved by the features of independent claim 1.
Vorteilhafte Ausgestaltungen und Weiterbildungen, welche einzeln oder in Kombination miteinander einsetzbar sind, sind Gegenstand der Unteransprüche.advantageous Embodiments and developments, which individually or in combination can be used with each other, are the subject of the dependent claims.
Die erfindungsgemäße Radialkolbenpumpe mit einem Pumpengehäuse; wenigstens einer Pumpeneinheit umfassend einen Pumpenkolben und einen Zylindereinsatz, in dem der Pumpenkolben hin- und her bewegbar gelagert ist; sowie einer Exzenterwelle, über die die Pumpeneinheit antreibbar ist; zeichnet sich dadurch aus, dass der Pumpenkolben über einen Pleuel und einen Kreuzkopf mit der Exzenterwelle verbunden ist. Durch die Verwendung eines Pleuels in Verbindung mit einem Kreuzkopf wird in vorteilhafter Weise die Reibung zwischen den Bauteilen minimiert und dadurch die Lebensdauer der Bauteile erhöht.The inventive radial piston pump with a pump housing; at least one pump unit comprising a pump piston and a cylinder insert in which the pump piston reciprocates is stored; and an eccentric shaft, via which the pump unit can be driven is; is characterized by the fact that the pump piston via a Connecting rod and a crosshead is connected to the eccentric shaft. By using a connecting rod in conjunction with a crosshead Advantageously, the friction between the components is minimized and thereby increases the life of the components.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass der Pleuel und der Kreuzkopf mittels eines Bolzens gegeneinander schwenkbar verbunden sind. Der Kreuzkopf ist in einer Öffnung im Pumpengehäuse geführt, wodurch sich die Drehbewegung der Exzenterwelle auf einfache Weise in eine Linearbewegung umwandeln lässt. Vorzugsweise ist der Kreuzkopf mittels zweier Gleitlagerbuchsen auf dem Bolzen gelagert. Anstelle der Gleitlager können auch Wälzlager Anwendung finden.A preferred embodiment of the invention provides that the connecting rod and the crosshead by means of a bolt against each other pivotally connected are. The crosshead is guided in an opening in the pump housing, whereby the rotational movement of the eccentric shaft in a simple manner in a linear movement converts. Preferably, the crosshead is by means of two plain bearing bushes stored on the bolt. Instead of plain bearings can also roller bearing Find application.
Die Kräfte werden vorteilhaft von den Gleitlagerbuchsen aufgenommen, wodurch die Reibung zwischen den Bauteilen weiter verringert wird. Die Gleitlagerbuchsen können hohe Kräfte gut aufnehmen und ermöglichen somit eine hohe Lebensdauer der Radialkolbenpumpe.The personnel are advantageously absorbed by the plain bearing bushes, whereby the friction between the components is further reduced. The plain bearing bushes can high forces good record and enable thus a long service life of the radial piston pump.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass der Pumpenkolben formschlüssig mit dem Kreuzkopf verbunden ist. Durch die formschlüssige Verbindung sind keine zusätzlichen Rückholelemente für den Kolben notwendig.A Another preferred embodiment of the invention provides that the Pump piston positive fit connected to the crosshead. Due to the positive connection are not additional return elements for the Piston necessary.
Erfindungsgemäß bevorzugt weist der Kreuzkopf eine T-Nut auf, die mit einem am Pumpenkolben ausgebildeten Absatz eine formschlüssige Verbindung zwischen Pumpenkolben und Kreuzkopf ausbildet. Eine solche T-Nut ist verhältnismäßig einfach in den Kreuzkopf auszubilden und gewährleistet vorteilhaft eine einfache und sehr sichere Verbindung zwischen dem Kreuzkopf und dem Pumpenkolben auch bei hohen Belastungen sowie hohen Drehzahlen.According to the invention, the crosshead preferably has a T-slot, which forms a positive connection between the pump piston and the crosshead with a shoulder formed on the pump piston formed. Such a T-slot is relatively easy to form in the crosshead and advantageously ensures a simple and very secure connection between the crosshead and the pump piston, even at high loads and high speeds.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass der Kreuzkopf im Wesentlichen zylindrisch ausgebildet und in einer im Pumpengehäuse ausgebildeten Bohrung geführt ist. Die im Wesentlichen zylindrische Ausbildung des Kreuzkopfes lässt sich gleichermaßen einfach wie preiswert beispielsweise durch Drehen herstellen. Ebenso ist die im Pumpengehäuse korrespondierende Bohrung auf einfache Weise, beispielsweise durch Bohren, herstellbar.A Further advantageous embodiment of the invention provides that the crosshead is substantially cylindrical and formed in a in the pump housing trained bore out is. The substantially cylindrical design of the crosshead let yourself equally easy as inexpensive to produce for example by turning. As well is the one in the pump housing Corresponding hole in a simple manner, for example by Drilling, producible.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass der Kreuzkopf parallel zu seiner Längsachse wenigstens eine Abflachung aufweist. Durch die Abflachung ergibt sich eine einfache Entlüftung. Die Luft kann dadurch in vorteilhafter Weise bei der Aufwärtsbewegung des Kreuzkopfes aus dem Zwischenraum zwischen dem Zylindereinsatz und dem Kreuzkopf entweichen. Anderenfalls müsste diese Luft jeweils komprimiert werden, was zu einer Verringerung des Wirkungsgrades führen und die Funktion der Radialkolbenpumpe erheblich behindern würde.A Another preferred embodiment of the invention provides that the Crosshead parallel to its longitudinal axis has at least one flat. Due to the flattening results a simple vent. The air can thereby advantageously in the upward movement of the crosshead from the space between the cylinder insert and escape the crosshead. Otherwise, this air would have to be compressed which lead to a reduction of the efficiency and would significantly impede the function of the radial piston pump.
Der erfindungsgemäßen Radialkolbenpumpe liegt der Gedanke zugrunde anstelle eines Gleitschuhs ein Pleuel zu verwendet, der über einen Kreuzkopf den Pumpenkolben hin und her bewegt. Die Umwandlung der Drehbewegung der Exzenterwelle in eine lineare Hubbewegung des Kreuzkopfes und damit des Pumpenkolbens erfolgt bevorzugt über Gleitlager, welche die auftretenden Kräfte sehr gut aufnehmen können. Hierdurch ergibt sich eine im Vergleich zum Stand der Technik wesentlich langlebigere Ausbildung einer Radialkolbenpumpe auch bei sehr hohen Drücken bzw. Drehzahlen, wie sie z.B. bei Kraftstoffhochdruckpumpen auftreten, wofür sich die vorliegende Erfindung insbesondere eignet.Of the Radial piston pump according to the invention the idea is based on a connecting rod instead of a sliding shoe to use that over a crosshead moves the pump piston back and forth. The transformation the rotational movement of the eccentric shaft in a linear stroke of the Crosshead and thus the pump piston is preferably via plain bearings, which the occurring forces can absorb very well. This results in a significant compared to the prior art more durable training of a radial piston pump even at very high To press or rotational speeds, as e.g. occur in high-pressure fuel pumps, what the present invention is particularly suitable.
