Description
Die Erfindung betrifft Schmierölpumpen von Verbrennungsmotoren.The Invention relates to lubricating oil pumps of internal combustion engines.
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.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 is conveyed by mostly several suction stages in 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.

Weiterhin sind auch kurzerbauende, mehrstufige Ölpumpen mit paralleler Antriebsanordnung von Förderstufen und dann erhöhter Wellenachsanzahl bekannt.Farther are also short-building, multi-stage oil pumps with parallel drive arrangement of funding levels and then heightened Shaft axle number known.

Nachteilig an den bekannten Schmierölpumpen ist, dass sie einen relativ großen Platzbedarf haben.adversely on the known lubricating oil pumps is that they are a relatively large one Have space.
Der Erfindung liegt die Aufgabe zugrunde, eine mehrstufige Schmierölpumpe vorzuschlagen, die besonders kompakt baut und damit beispielsweise für Trockensumpf-Ölschmiervorrichtungen geeignet ist.Of the Invention has for its object to propose a multi-stage lubricating oil pump, the particularly compact builds and thus suitable for example for dry sump oil lubrication devices is.
Die Erfindung löst das Problem durch eine mehrstufige Schmierölpumpe gemäß Anspruch 1.The Invention solves the problem by a multi-stage lubricating oil pump according to claim 1.
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.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 liefern 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 they always have to deliver a certain minimum basic delivery volume also in two stages with a basic stage and a regulating conveyor stage accomplished be.
