Description
Die Erfindung betrifft eine Pumpe zum Fördern eines Fluids, insbesondere eines Kraftwagens, gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a pump for conveying a fluid, in particular a motor vehicle, according to the preamble of patent claim 1.
Eine solche Pumpe zum Fördern eines Fluids ist der
Ferner ist die Pumpe als variable Pumpe ausgebildet. Dies bedeutet, dass die Pumpe eine variable beziehungsweise variabel einstellbare Verdrängung aufweist. Mit anderen Worten ist eine Fördermenge der Pumpe variabel einstellbar. Dies bedeutet, dass eine mittels der Pumpe je Zeiteinheit zu fördernde Menge des Fluids variabel einstellbar ist. Hierzu ist das Verstellelement relativ zu dem Gehäuseteil und relativ zu dem Pumpenelement bewegbar, insbesondere verschwenkbar. Durch Bewegen, insbesondere Verschwenken, des Verstellelements wird die Fördermenge der Pumpe verändert und dadurch eingestellt.Furthermore, the pump is designed as a variable pump. This means that the pump has a variable or variably adjustable displacement. In other words, a flow rate of the pump is variably adjustable. This means that an amount of fluid to be delivered by the pump per unit of time is variably adjustable. For this purpose, the adjusting element is movable relative to the housing part and relative to the pump element, in particular pivotable. By moving, in particular pivoting, the adjusting element, the delivery rate of the pump is changed and thereby adjusted.
Aufgabe der vorliegenden Erfindung ist es, eine Pumpe der eingangs genannten Art derart weiterzuentwickeln, dass der Verschleiß der Pumpe auch bei einer hohen Lebensdauer besonders gering gehalten werden kann.Object of the present invention is to develop a pump of the type mentioned in such a way that the wear of the pump can be kept particularly low even with a long service life.
Diese Aufgabe wird durch eine Pumpe mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a pump having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Um eine Pumpe der im Oberbegriff des Patentanspruchs 1 angegebenen Art derart weiterzuentwickeln, dass die Pumpe auch bei einer sehr hohen Lebensdauer einen nur sehr geringen Verschleiß aufweist, ist es erfindungsgemäß vorgesehen, dass das Verstellelement über ein Reibung und somit Verschleiß minderndes, separat vom Verstellelement und separat vom Gehäuseteil ausgebildetes Einlegeteil am Gehäuseteil gelagert ist. Beispielsweise ist das Verstellelement über das Einlegeteil am Gehäuseteil gleitgelagert. Durch Verwendung des Einlegeteils zwischen dem Gehäuseteil und dem Verstellelement kann eine besonders vorteilhafte Reib- oder Gleitpaarung mit vorteilhaften Gleiteigenschaften zwischen dem Einlegeteil und dem relativ zu dem Einlegeteil bewegbaren, insbesondere verschwenkbaren, Verstellelement geschaffen werden, so dass das Verstellelement bei einer Bewegung des Verstellelements relativ zu dem Gehäuseteil und relativ zu dem vorzugsweise am Gehäuseteil festgelegten Einlegeteil besonders reibungs- und somit verschleißarm am Einlegeteil abgleiten und/oder abwälzen kann.To further develop a pump specified in the preamble of claim 1 type such that the pump has a very high wear even a very low wear, it is provided according to the invention that the adjustment via a friction and thus wear-reducing, separately from the adjustment and mounted separately from the housing part insert is mounted on the housing part. For example, the adjusting element is slidably mounted on the insert part on the housing part. By using the insert between the housing part and the adjusting element, a particularly advantageous friction or sliding pair with advantageous sliding properties between the insert and the movable relative to the insert part, in particular pivotable adjustment can be created, so that the adjustment during a movement of the adjusting relative to the housing part and relative to the preferably fixed to the housing part insert particularly friction and thus wear sliding on the insert and / or can roll off.
Vorzugsweise ist es vorgesehen, dass das Einlegeteil aus einem hochfesten Werkstoff gebildet ist. Als besonders vorteilhaft hat es sich gezeigt, wenn das Einlegeteil einen Grundkörper aufweist, welcher außenumfangsseitig zumindest teilweise mit einer Reibung und somit Verschleiß mindernden Beschichtung versehen ist. Dabei ist das Verstellelement über diese Beschichtung am Gehäuseteil gelagert, so dass sich die Reibung und somit der Verschleiß der Pumpe besonders gering halten lassen.Preferably, it is provided that the insert is formed from a high-strength material. To be particularly advantageous, it has been shown, when the insert has a base body, which is provided on the outer peripheral side at least partially with a friction and thus wear-reducing coating. In this case, the adjusting element is mounted on this coating on the housing part, so that it is possible to keep the friction and thus the wear of the pump particularly low.
Zur Realisierung einer besonders verschleißarmen und definierten Lagerung ist es vorzugsweise vorgesehen, dass das Verstellelement einen Vorsprung aufweist, über welchen das Verstellelement über das Einlegeteil am Gehäuseteil gelagert ist. Dabei greift der Vorsprung zumindest teilweise in eine korrespondierende Aufnahme des Einlegeteils ein.To realize a particularly low-wear and defined storage, it is preferably provided that the adjusting element has a projection, via which the adjusting element is mounted on the insert part on the housing part. The projection engages at least partially in a corresponding receptacle of the insert.
Durch den Einsatz des Einlegeteils kann eine zumindest nahezu verschleißfreie Gleitpaarung insbesondere zwischen dem Verstellelement und dem Einlegeteil geschaffen werden, so dass ein Druckabfall des Fluids auch über eine hohe Betriebs- und Lebensdauer der Pumpe hinweg vermieden oder zumindest besonders gering gehalten werden kann.Through the use of the insert, an at least almost wear-free sliding pair can be created, in particular between the adjusting element and the insert, so that a pressure drop of the fluid can also be avoided or at least kept particularly low over a long operating and service life of the pump.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung. Die vorstehend in der Beschreibung genannten Merkmale und Merkmalskombinationen sowie die nachfolgend in der Figurenbeschreibung genannten und/oder in den Figuren alleine gezeigten Merkmale und Merkmalskombinationen sind nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar, ohne den Rahmen der Erfindung zu verlassen.Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing.
