Abstract
Description
Die vorliegende Erfindung betrifft eine Radialkolbenpumpe mit mehreren Pumpeneinheiten, gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a radial piston pump with several pump units, according to the preamble of claim 1.
Eine derartige Radialkolbenpumpe
ist bereits aus der
Die Radialkolbenpumpe weist drei in einem Abstand von 120 Grad zueinander angeordnete Pumpeneinheiten auf. Jede Pumpeneinheit besitzt einen radial im Pumpengehäuse längs bewegbar geführten Pumpenkolben. Der Pumpenkolben liegt an einem Gleitschuh an, der sich am Hubring abstützt. Hierzu weist der Hubring eine der Anzahl der Pumpenkolben entsprechende Zahl von Abflachungen auf. Um den Kolben mit dem ihm zugeordneten Gleitschuh beim Betrieb der Kolbenpumpe ständig in Anlage an den Hubring zu halten, weist jede Pumpeneinheit eine Gleitschuhanordnung mit einer Rückstellfeder sowie einem Stützkolben auf. Die Rückstellfeder stützt sich mit einer Stirnseite am Pumpenzylinder und mit der anderen Stirnseite am Stützkolben ab. Durch das Vorspannen der Stützfeder wird gewährleistet, dass der Gleitschuh ständig in Kontakt mit dem Hubring bleibt.The radial piston pump has three Pump units arranged at a distance of 120 degrees from each other on. Each pump unit has a radially longitudinally movable in the pump housing out Pump piston. The pump piston rests on a sliding shoe that is supported on the cam ring. For this the cam ring has a number corresponding to the number of pump pistons Number of flattening on. To the piston with the associated with it Sliding shoe in operation of the piston pump constantly in contact with the cam ring to hold, each pump unit has a slide shoe arrangement a return spring and a support piston on. The return spring supports one end of the pump cylinder and the other Front side on the support piston from. By preloading the support spring is guaranteed that the shoe is constantly remains in contact with the cam ring.
Eine aus der
Die Aufgabe der Erfindung ist es daher eine sichere und einfache Montage der Gleitschuhanordnung zu ermöglichen und die Flächenpressung an der Aufstandsfläche zwischen Gleitschuh und Hubring zu verringern.The object of the invention is therefore a safe and simple assembly of the slide shoe arrangement to enable and the surface pressure on the footprint between sliding shoe and cam ring.
Die Aufgabe wird gelöst durch die Merkmale des unabhängigen Patentanspruchs. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The task is solved by the characteristics of the independent Claim. Advantageous embodiments of the invention are in the subclaims characterized.
Die Erfindung zeichnet sich dadurch aus, dass die Verbindung zwischen dem Gleitschuh und dem Stützkolben unmittelbar formschlüssig ist, wobei der Formschluss durch eine Rastverbindung erfolgt. Durch den Formschluss mittels Rastverbindung lässt sich eine besonders einfache Montage gewährleisten. Ein zusätzliches Sichern mittels Sprengring entfällt. Durch den Wegfall eines zusätzlichen Bauelementes reduzieren sich zudem die Materialkosten. Nach dem Einrasten weisen die beiden Bauteile ein Spiel zueinander auf, wodurch ein Achsversatz zwischen dem Gleitschuh und dem Stützkolben ausgeglichen werden kann und eine vollflächige Anlage zwischen dem Gleitschuh und dem Hubring gewährleistet ist.The invention is characterized by this from that the connection between the shoe and the support piston immediately positive is, the positive connection is carried out by a snap connection. By the form fit by means of a snap connection can be particularly simple Ensure assembly. An additional Securing using a snap ring is not necessary. By eliminating an additional Component also reduce the material costs. After this When snapped in, the two components have a play with one another, which an axis offset between the slide shoe and the support piston can be compensated for and a full-surface contact between the shoe and the cam ring guaranteed is.
Eine besonders vorteilhafte Ausgestaltung der Erfindung sieht vor, den Gleitschuh in Form eines Stempels auszubilden, wobei die Stirnseite mit der größeren Querschnittsfläche am Hubring aufliegt. Hierdurch kann eine besonders große Auflagefläche am Hubring erzielt werden, wodurch die Flächenpressung gegenüber dem Stand der Technik deutlich reduziert werden kann.A particularly advantageous embodiment of the The invention provides for the slide shoe to be in the form of a stamp, the end face with the larger cross-sectional area on the cam ring rests. This enables a particularly large contact surface on the cam ring can be achieved, reducing the surface pressure across from the prior art can be significantly reduced.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand der schematischen Zeichnungen näher erläutert. Es zeigen:Embodiments of the invention are explained in more detail below with the aid of the schematic drawings. It demonstrate:
Selbstverständlich ist die Erfindung nicht auf die in den Ausführungsbeispielen gezeigte Rastverbindung beschränkt sondern schließt alle dem Fachmann bekannten Rastverbindungen ein. Insbesondere sind auch solche Rastverbindungen eingeschlossen, bei denen der Stützkolben vom Gleitschuh umschlossen wird und in ihm einrastet.Of course, the invention is not to those in the exemplary embodiments shown locking connection limited but closes all locking connections known to the expert. In particular are including such locking connections where the support piston is enclosed by the slide shoe and snaps into place.
