Description
Die Erfindung betrifft eine Kraftstoffpumpe und eine Kraftstofffördereinheit mit einer solchen Kraftstoffpumpe zur Verwendung in einem Kraftstofftank eines Fahrzeugs zur Förderung von Kraftstoff zu einem Verbrennungsmotor. Unter einem Fahrzeug ist dabei jede Art von Fahrzeug zu verstehen, welches zum Betrieb mit einem flüssigen und/oder gasförmigen Kraftstoff versorgt werden muss, insbesondere aber Personenkraftwagen und/oder Nutzfahrzeuge.The invention relates to a fuel pump and a fuel delivery unit with such a fuel pump for use in a fuel tank of a vehicle for delivering fuel to an internal combustion engine. Under a vehicle is to understand any type of vehicle, which must be supplied for operation with a liquid and / or gaseous fuel, but in particular passenger cars and / or commercial vehicles.
Solch eine Kraftstoffpumpe und Kraftstofffördereinheit sind aus dem Stand der Technik vielfach bekannt. Die Kraftstoffpumpe umfasst neben einer Pumpenstufe auch einen die Pumpenstufe antreibenden Elektromotor. Der Elektromotor und die Pumpenstufe sind dabei mit einem Blechmantel bzw. Blechzylinder verrollt, welcher im Wesentlichen sowohl den Elektromotor als auch die Pumpenstufe einkapselt und dabei dichtend umschließt. Eine bezüglich z.B. einer Schraubenpumpenstufe druckseitig ausgebildete Schnittstelle zum Elektromotor einerseits und eine bezüglich der Schraubenpumpenstufe saugseitige Anordnung einer axial wirkenden Dichtung bzw. Axialdichtung andererseits beeinflussen eine sich beim Verrollen des Blechmantels einstellende Verzwängung bzw. Verspannung der Schraubenpumpenstufe. Diese Verspannung erstreckt sich dabei über die ganze Schraubenpumpenstufe und führt zu einer statisch über- bzw. unbestimmten Einbausituation der Schraubenpumpenstufe.Such a fuel pump and fuel delivery unit are well known in the art. In addition to a pump stage, the fuel pump also includes an electric motor driving the pump stage. The electric motor and the pump stage are rolled with a metal jacket or sheet metal cylinder, which encapsulates substantially both the electric motor and the pump stage and thereby enclosing sealing. A reference to e.g. a screw pump stage formed on the pressure side interface to the electric motor on the one hand and with respect to the screw pump stage suction side arrangement of an axially acting seal or axial seal on the other hand affect adjusting a rolling of the sheet metal jacket Verzwängung or clamping the screw pump stage. This tension extends over the entire screw pump stage and leads to a static over or indefinite installation situation of the screw pump stage.
Eine der Erfindung zugrunde liegende Aufgabe ist es, die zuvor erwähnte Verzwängung bzw. Verspannung beim Verbau einer solchen Kraftstoffpumpe zu vermeiden.An object underlying the invention is to avoid the aforementioned Verzwängung or tension when installing such a fuel pump.
Eine weitere der Erfindung zugrunde liegende Aufgabe ist es, an Bauraum für eine solche Kraftstoffpumpe einzusparen.Another object of the invention is to save on space for such a fuel pump.
Diese Aufgabe wird durch den Anspruch 1 gelöst, der eine Kraftstoffpumpe unter Schutz stellt. Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by claim 1, which provides a fuel pump under protection. Advantageous embodiments of the invention are the subject of the dependent claims.
Es wird eine Kraftstoffpumpe vorgeschlagen, umfassend einen Elektromotor, eine durch den Elektromotor antreibbare Pumpenstufe und ein den Elektromotor und die Pumpenstufe aufnehmendes Kraftstoffpumpengehäuse. Vom Kraftstoffpumpengehäuse führen dabei sowohl ein Anschlussstutzen zur Verbindung mit einer Kraftstoffleitung als auch eine Anschlussbuchse zur elektrischen Anbindung des Elektromotors weg.A fuel pump is proposed, comprising an electric motor, a pump stage which can be driven by the electric motor, and a fuel pump housing accommodating the electric motor and the pump stage. From the fuel pump housing lead both a connection piece for connection to a fuel line and a connector socket for electrical connection of the electric motor away.
Dabei wird vorgeschlagen, dass zumindest der Anschlussstutzen quer zu einer Längsrichtung der Kraftstoffpumpe vom Kraftstoffpumpengehäuse weggeführt ist, wobei das Kraftstoffpumpengehäuse ein erstes Gehäuseteil aus Kunststoff zur Aufnahme des Elektromotors und ein zweites Gehäuseteil aus Kunststoff zur Aufnahme der Pumpenstufe aufweist. Der Anschlussstutzen ist dabei am ersten Gehäuseteil oder am zweiten Gehäuseteil angeformt, wobei das erste Gehäuseteil mit dem zweiten Gehäuseteil gefügt und stoffschlüssig verbunden ist.It is proposed that at least the connecting piece is led away transversely to a longitudinal direction of the fuel pump from the fuel pump housing, wherein the fuel pump housing has a first housing part made of plastic for receiving the electric motor and a second housing part made of plastic for receiving the pump stage. The connecting piece is formed on the first housing part or on the second housing part, wherein the first housing part is joined to the second housing part and materially connected.
Unter einer Anformung ist dabei zu verstehen, dass das jeweilige Gehäuseteil mit dem Anschlussstutzen einteilg bzw. einstückig ausgebildet ist. D.h., dass der Anschlussstutzen bei der kunststofftechnischen Herstellung des Gehäuseteils mit ausgebildet wird.Under a Anformung is to be understood that the respective housing part einteilg with the connection piece or is integrally formed. In other words, the connecting piece is formed during the manufacture of the housing by the plastics industry.
Durch die vorgeschlagene Kraftstoffpumpe wird eine in Längsrichtung der Kraftstoffpumpe kompaktere Bauweise erzielt. Hinzu kommt, dass die eingangs beschriebene Verrollung eines Blechmantels bzw. Blechzylinders zur Einkapselung und dichtenden Umschließung des Elektromotors und der Pumpenstufe vorteilhafterweise entfällt. Eine damit einhergehend sich einstellende Verzwängung bzw. Verspannung einer Pumpenstufe, etwa in Gestalt einer Schraubenpumpenstufe - wie eingangs beschrieben - entfällt somit ebenfalls.By the proposed fuel pump, a more compact in the longitudinal direction of the fuel pump construction is achieved. In addition, the roll-up of a sheet-metal jacket or sheet-metal cylinder described above for encapsulation and sealing enclosure of the electric motor and the pump stage is advantageously eliminated. A concomitantly adjusting Verzwängung or tension of a pump stage, such as in the form of a screw pump stage - as described above - thus also deleted.
Nach einer Ausführungsform ist die Pumpenstufe dabei derart zum ersten Gehäuseteil angeordnet, dass die Pumpenstufe mit dem ersten Gehäuseteil einen in den Anschlussstutzen mündenden Kraftstoffkanal bildet, welcher den Kraftstoff zumindest quer zur Längsrichtung der Kraftstoffpumpe führt. Dabei kann die die Pumpenstufe mit dem ersten Gehäuseteil ferner einen Kraftstoffkanal bilden, der in eine Aufnahme des ersten Gehäuseteils mündet, in welcher ein Rotor des Elektromotors angeordnet ist, wobei der Kraftstoffkanal den Kraftstoff zumindest in der Längsrichtung der Kraftstoffpumpe führt.According to one embodiment, the pump stage is arranged in such a way to the first housing part that the pump stage with the first housing part forms a fuel channel opening into the connecting piece, which leads the fuel at least transversely to the longitudinal direction of the fuel pump. In this case, the pump stage with the first housing part further form a fuel channel, which opens into a receptacle of the first housing part, in which a rotor of the electric motor is arranged, wherein the fuel channel leads the fuel at least in the longitudinal direction of the fuel pump.
Nach einer weiteren Ausführungsform kann auch die Anschlussbuchse quer zur Längsrichtung der Kraftstoffpumpe vom Kraftstoffpumpengehäuse weggeführt sein, wobei auch die Anschlussbuchse am ersten Gehäuseteil oder am zweiten Gehäuseteil angeformt sein kann. Damit lässt sich eine in Längsrichtung der Kraftstoffpumpe noch kompaktere Bauweise erzielen.According to a further embodiment, the connecting bushing can also be led away from the fuel pump housing transversely to the longitudinal direction of the fuel pump, it also being possible for the connecting bushing to be integrally formed on the first housing part or on the second housing part. This can be achieved in the longitudinal direction of the fuel pump even more compact design.
Unter einer Anformung ist auch hierbei zu verstehen, dass das jeweilige Gehäuseteil mit der Anschlussbuchse einteilg bzw. einstückig ausgebildet ist. D.h., dass die Anschlussbuchse bei der kunststofftechnischen Herstellung des Gehäuseteils mit ausgebildet wird.Under an Anformung is also to understand here that the respective housing part einteilg with the connection socket or is integrally formed. That is, that the socket is formed in the plastic manufacturing of the housing part with.
Nach einer weiteren Ausführungsform kann auch ein drittes als Deckel fungierendes Gehäuseteil aus Kunststoff vorgesehen sein, welches mit dem ersten Gehäuseteil gefügt und stoffschlüssig verbunden ist.According to a further embodiment, a third functioning as a cover housing part made of plastic may be provided, which with the first housing part joined and materially connected.
Die zuvor beschriebenen stoffschlüssigen Verbindungen können dabei als Verklebung und/oder Verschweißung ausgebildet sein. Die Verschweißung kann dabei z.B. als Ultraschallschweißverbindung oder Laserschweißverbindung ausgebildet sein. Das Ultraschallschweißen und Laserschweißen sind dem Fachmann bekannt und werden im Weiteren nicht näher beschrieben. Auch sind die für solche stoffschlüssigen Verbindungen geeigneten Klebstoffe dem Fachmann bekannt und werden im Weiteren nicht näher beschrieben.The cohesive connections described above can be designed as gluing and / or welding. The welding may be e.g. be formed as ultrasonic welding or laser welding connection. The ultrasonic welding and laser welding are known in the art and will not be described in detail. The adhesives suitable for such cohesive connections are also known to the person skilled in the art and will not be described in detail below.
Nach einer weiteren Ausführungsform kann die Pumpenstufe in Gestalt einer Strömungspumpe oder Verdrängungspumpe ausgebildet sein. Die Pumpenstufe kann dabei als deckellose Schraubenpumpenstufe ausgebildet sein, wobei ein Pumpengehäuse der Pumpenstufe den zweiten Gehäuseteil bildet. Alternativ dazu kann die Pumpenstufe als Schraubenpumpenstufe ausgebildet sein, wobei ein mit einem Pumpengehäuse der Pumpenstufe gefügter Pumpendeckel den zweiten Gehäuseteil bildet.According to a further embodiment, the pump stage may be in the form of a flow pump or displacement pump. The pump stage can be designed as a capless screw pump stage, wherein a pump housing of the pump stage forms the second housing part.
