Abstract
Description
Die Erfindung betrifft mehrstufige Schierölpumpen von Verbrennungsmotoren, insbesondere Ölpumpenausführungen mit einer Außenzahnrad-Regelölpumpe als Druckstufe. Mehrstufige Ölpumpen haben die Aufgabe, mittels mindestens einer Druckstufe eine ausreichende Motorschmierung sicherzustellen und bei Bedarf auch über eine oder mehrere Saugstufen von den Schmierstellen des Verbrennungsmotors in die Ölwannen zurückfließendes Rücklauföl dem Ansaugbereich der Druckstufe zuzuführen. Beispielsweise kann bei Sport oder Geländefahrzeugen mit hohen Beschleunigungen oder größeren Fahrzeugschräglagen ein Trockensumpf-Schmiersystemen erforderlich sein, bei dem das sich in der Ölwanne ansammelnde Schmieröl von meist mehreren Saugstufen in einen höherliegenden Hauptölbehälter gefördert wird, von dem aus die Druckstufe das Schmieröl absaugt. The The invention relates to multi-stage oil pumps of internal combustion engines, especially oil pump versions with an external gear control oil pump as Pressure stage. Multi-stage oil pumps have the task, by means of at least one pressure level sufficient To ensure engine lubrication and, if necessary, also via a or several suction stages from the lubrication points of the internal combustion engine in the oil pans returning return oil to the intake area to supply the pressure stage. For example, in sports or off-road vehicles with high accelerations or larger vehicle slants Dry sump lubrication systems may be required in which the in the oil pan accumulating lubricating oil of usually several suction stages is conveyed into a higher lying main oil tank, from which the pressure stage sucks the lubricating oil.
Eine mehrstufig ausgeführte Ölpumpe benötig einen ihren Funktionen gemäßen Bauraum. Im einfachsten Ausführungsfall werden die einzelnen Pumpenstufen hintereinanderliegend in Reihenanordnung mit entsprechender Baulänge ausgebildet, wobei die Förderzahnräder auf nur zwei Wellenachsen angeordnet sind. Diese Reihenanordnung kann insbesondere dann bauraumkritisch sein, wenn die Druckstufe der Ölpumpe als Außenzahnrad-Regelölpumpe mit axialer Zahnradverschiebung in Kombination mit mehren Saugstufen ausgeführt ist.A multi-stage oil pump requires one their functions in accordance with space. In the simplest embodiment The individual pump stages are arranged one behind the other in a row arrangement with appropriate length formed, with the conveyor gears on only two shaft axes are arranged. This series arrangement can in particular then be space critical, if the pressure level of the oil pump than External gear control oil pump with axial gear shift in combination with several suction stages accomplished is.
Die deutsche Anmeldung 10144693.4 zeigt eine mehrstufige Ölpumpe mit einer als Außenzahnrad-Regelölpumpe ausgebildeten Druckstufe, bei der aufgrund von drei Saugstufen die Reihenanordnung der Pumpenstufen zu einer erheblichen Gesamtbaulänge führt.The German application 10144693.4 shows a multi-stage oil pump a trained as external gear oil pump Pressure stage, due to the three suction stages, the series arrangement of Pump stages leads to a significant overall length.
Weitehin sind auch kürzerbauende, mehrstufige Ölpumpen mit paralleler Antriebsanordnung von Förderstufen und dann erhöhter Wellenachsanzahl bekannt. Eine sehr kompakte Ausführung einer zweistufigen Ölpumpe kann erreicht werden, wenn nur ein gemeinsames, erstes Förderzahnrad beider Förderstufen mit den beiden beispielsweise gegenüberliegenden, zweiten Förderzahnrädern im Zahneingriff steht.Weitehin are also shorter-building, multi-stage oil pumps with parallel drive arrangement of conveyor stages and then increased shaft axle number known. A very compact design a two-stage oil pump can be achieved if only a common, first conveyor gear Both funding levels with the two, for example, opposite, second conveyor gears in Tooth engagement is.
Der axiale Bauraumbedarf einer Außenzahnrad-Regelölpumpen mit axialer Relativverschiebung der kämmenden Förderzahnräder ist insbesondere von der Breitenauslegung ihrer Förderzahnräder abhängig. Beispielsweise um 10 mm verbreiterte Förderzahnräder lassen eine auch um 10 mm größerer Relativverschiebung zwischen den Förderzahnrädern zu, so dass die Ölpumpenverlängerung dann mindestens 20 mm ausmacht. Da auch eine die Fördermenge variierende Regelölpumpe immer eine gewisse, minimale Grundfördermenge liefem muss, könnte sie auch zweistufig mit einer Grundförderstufe und einer Regelförderstufe ausgeführt sein.Of the axial space requirement of an external gear control oil pump with axial relative displacement of the meshing conveyor gears is in particular of the Width design of their conveyor gears depends. For example let 10 mm widened conveyor gears an even 10 mm larger relative displacement between the conveyor gears, so that the oil pump extension then make at least 20 mm. As well as the flow rate varying control oil pump It always has a certain minimum basic delivery, it could also in two stages with a basic stage and a regulating conveyor stage accomplished be.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine mehrstufige Schmierölpumpe mit einer Außenzahnrad-Regelölpumpe in kompakter Bauweise auszuführen.Of the present invention is based on the object, a multi-stage Lubricating oil pump with an external gear oil pump in compact design.
Diese Aufgabe wird erfindungsgemäß durch eine mehrstufige Ölpumpenausführung mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst.These The object is achieved by a Multi-stage oil pump version with the features characterized in claim 1 solved.
Für mehrstufige Schmierölpumpen mit einer Regelölpumpe als Druckstufe ist erfindungsgemäß vorgesehen, die Förderzahnräder mehrerer Förderstufen auf mindestens drei parallelen Wellenachsen anzuordnen. Hierdurch wird der regelungsbedingt längere Bauraum der Außenzahnrad-Regelölpumpe für weitere Förderstufen in teilweiser Parallelanordnung zur Außenzahnrad-Regelölpumpe bauraumvorteilhaft genutzt, so dass eine sehr kompakte Ölpumpeneinheit entsteht.For multi-level Oil pump with a regular oil pump as pressure step is provided according to the invention, the conveyor gears of several funding levels to arrange on at least three parallel shaft axes. hereby becomes longer due to the regulation Space of external gear oil pump for further funding levels in partial parallel arrangement to the external gear oil pump installation space advantageous used, so that a very compact oil pump unit is created.
