Abstract
Description
Die vorliegende Erfindung betrifft eine Antriebsanordnung, insbesondere für ein Kraftfahrzeug, mit einer Aggregateinheit, die mit einem Getriebe zur Über- und/oder Untersetzung eines der von der Aggregateinheit erzeugten oder eines der Aggregateinheit zugeführten Antriebsmoments in antriebswirksamer Verbindung steht.The present invention relates to a drive arrangement, in particular for a motor vehicle, having an aggregate unit which is in drive-active connection with a gearbox for the transmission and / or reduction of one of the drive unit generated by the unit unit or one of the unit unit supplied.
Derartige Antriebsanordnungen sind in vielen Varianten bekannt und finden in den unterschiedlichsten Bereichen Anwendung. Bei derartigen Antriebsanordnungen stellt sich in der Regel ein erhebliches Problem in Bezug auf eine effiziente Kühlung und Schmierung der beteiligten Komponenten, insbesondere der Aggregateinheit. Eine zuverlässige Abfuhr der bei Betrieb der Antriebsanordnung entstehenden Abwärme und eine zuverlässige Zufuhr von Schmiermittel sind entscheidend für die Betriebssicherheit und die Effizienz der Anordnung.Such drive arrangements are known in many variants and find application in a wide variety of applications. In such drive arrangements, as a rule, a considerable problem arises with regard to efficient cooling and lubrication of the components involved, in particular of the unit unit. A reliable dissipation of the heat generated during operation of the drive assembly waste heat and a reliable supply of lubricant are critical to the reliability and efficiency of the arrangement.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Antriebsanordnung zu schaffen, die ein verbessertes Schmier- und Kühlkonzept aufweist, um die Betriebssicherheit und die Effizienz der Antriebsanordnung zu steigern.It is therefore an object of the present invention to provide a drive assembly having an improved lubrication and cooling concept to increase the reliability and efficiency of the drive assembly.
Diese Aufgabe wird durch eine Antriebsanordnung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a drive arrangement having the features of claim 1.
Erfindungsgemäß weist das Getriebe zumindest ein erstes Zahnrad und ein zweites Zahnrad auf, die miteinander kämmen und die zusammen eine Zahnradpumpe bilden. Durch die Zahnradpumpe ist der Aggregateinheit über einen Kanal kühlendes und/oder schmierendes Fluid zuführbar.According to the invention, the transmission has at least a first gear and a second gear, which mesh with each other and together form a gear pump. By the gear pump, the unit unit via a channel cooling and / or lubricating fluid can be fed.
Mit anderen Worten werden zwei Zahnräder des Drehmoment übertragenden Getriebes genutzt, um die Aggregateinheit mit Kühl- und/oder Schmiermittel zu versorgen. Die Zahnräder wirken dabei derart zusammen, dass sie eine Pumpwirkung erzeugen, mit der das genannte Fluid förderbar ist. Eine separate Pumpe zur Förderung des genannten Fluids entfällt daher. Dies führt zu Bauraum- und Kostenvorteilen. Außerdem ermöglicht die Nutzung des ohnehin vorhandenen Getriebes als Zahnradpumpe eine effiziente Fluidförderung, die in erster Linie von der Drehzahl der Zahnräder abhängig ist.In other words, two gears of the torque transmitting gear are used to provide the unit assembly with coolant and / or lubricant. The gears interact in such a way that they produce a pumping action with which said fluid can be conveyed. A separate pump for conveying the said fluid is therefore eliminated. This leads to space and cost advantages. In addition, the use of the already existing gear as a gear pump allows efficient fluid delivery, which is primarily dependent on the speed of the gears.
Gemäß einer Ausführungsform der Antriebsanordnung verläuft der Kanal zumindest abschnittsweise in einer mit einem Rotor der Aggregateinheit verbundenen Rotorwelle. Die Rotorwelle ist jene Welle, die von der Aggregateinheit direkt angetrieben wird oder die diese direkt antreibt. Durch die Führung des Fluids zumindest abschnittsweise in der Rotorwelle kann die Fluidzuführung sehr effizient gestaltet werden, ohne dass aufwendige Zufuhrkanäle geschaffen werden müssen. Bevorzugt ist der Kanal abschnittsweise koaxial zu einer Drehachse des Rotors angeordnet.According to one embodiment of the drive arrangement, the channel runs at least in sections in a rotor shaft connected to a rotor of the unit unit. The rotor shaft is the shaft that is driven directly by the unit or drives it directly. Due to the guidance of the fluid at least in sections in the rotor shaft, the fluid supply can be designed very efficiently, without the need for expensive supply channels. Preferably, the channel is arranged in sections coaxially to a rotational axis of the rotor.
Der Kanal kann radiale Öffnungen aufweisen, durch die das Fluid in radialer Richtung aus dem Kanal austreten kann. Bei einer Ausgestaltung des Kanals mit radialen Öffnungen macht man sich die Zentrifugalkraft zunutze, die bei Betrieb der Aggregateinheit auf das in dem Kanal befindliche Fluid wirkt. Sie treibt das Fluid durch die Öffnungen aus dem Kanal in das Innere der Aggregateinheit, um dort eine Schmierung und/oder eine Kühlung zu bewirken. Eine besonders effiziente Kühlung und/oder Schmierung wird erzielt, wenn die Öffnungen insbesondere derart angeordnet sind, dass Funktionskomponenten der Aggregateinheit zumindest abschnittsweise mit Fluid beaufschlagt werden, insbesondere wenn diese im Bereich der Stirnseiten der Aggregateinheit liegen. Beispielsweise sind – bei einer elektrischen Maschine als Aggregateinheit – Wicklungen eines Stators derartige Funktionskomponenten. Eine Benetzung der Wicklungsköpfe an den Stirnseiten des Stators – z. B. durch direktes Anspritzen mit Fluid aus dem Kanal – lässt sich mit vergleichsweise geringem konstruktiven Aufwand erreichen. Gleichzeitig wird eine hinreichend gute Kühlung erzielt.The channel may have radial openings through which the fluid can exit the channel in the radial direction. In an embodiment of the channel with radial openings makes use of the centrifugal force, which acts upon operation of the unit unit on the fluid located in the channel. It drives the fluid through the openings out of the channel into the interior of the unit unit in order to effect lubrication and / or cooling there. A particularly efficient cooling and / or lubrication is achieved when the openings are arranged in particular such that functional components of the unit unit are at least partially acted upon with fluid, especially if they are in the region of the end faces of the unit unit. For example, windings of a stator are such functional components in an electric machine as an aggregate unit. Wetting of the winding heads on the front sides of the stator - z. B. by direct injection with fluid from the channel - can be achieved with relatively little design effort. At the same time a sufficiently good cooling is achieved.
Es kann vorgesehen sein, dass das erste Zahnrad mit einer mit einem Rotor der Aggregateinheit verbundenen Rotorwelle drehfest verbunden ist. Dadurch ist es möglich, die Zahnradpumpe räumlich nahe an der Aggregateinheit anzuordnen, so dass die Zufuhrwege des Fluids vergleichsweise kurz sind.It can be provided that the first gear is rotatably connected to a connected to a rotor of the unit unit rotor shaft. Thereby, it is possible to arrange the gear pump spatially close to the unit unit, so that the supply paths of the fluid are comparatively short.
Der Kanal kann sich zumindest abschnittsweise durch das erste Zahnrad erstrecken. Insbesondere ist der Kanal zumindest abschnittsweise koaxial zu einer Drehachse des ersten Zahnrads angeordnet.The channel may extend at least in sections through the first gear. In particular, the channel is at least partially coaxial with a rotational axis of the first gear.
Gemäß einer vorteilhaften Ausführungsform umfasst die Zahnradpumpe ein Gehäuse mit einem Gehäusebauteil, das eine Druckkammer ausbildet, die mit dem Kanal in Verbindung steht. Das Gehäusebauteil kann einen ersten Leitabschnitt aufweisen, der das erste Zahnrad abschnittsweise in Umfangsrichtung umgibt. Ferner kann ein zweiter Leitabschnitt vorgesehen sein, der das zweite Zahnrad zumindest abschnittsweise in Umfangsrichtung umgibt, wobei die Druckkammer zwischen den beiden Leitabschnitten angeordnet ist. Die Leitabschnitte führen das von den Zahnrädern in Bewegung versetzte Fluid zu der Druckkammer hin, von wo aus es der Aggregateinheit zugeführt wird.According to an advantageous embodiment, the gear pump comprises a housing with a housing component, which forms a pressure chamber which communicates with the channel. The housing component may have a first guide portion which surrounds the first gear in sections in the circumferential direction. Further, a second guide portion may be provided, which surrounds the second gear at least partially in the circumferential direction, wherein the pressure chamber is arranged between the two guide sections. The guide portions guide the fluid which has been set in motion by the gears to the pressure chamber, from where it is supplied to the unit unit.
Zur Regulierung des der Zahnradpumpe zugeführten Fluids kann das Gehäuse der Zahnradpumpe einen Regulierungsabschnitt aufweisen, der ein Fluidreservoir bildet, das mit einem Fluidsumpf in einem Gehäuse des Getriebes in Fluidverbindung steht. In dem Fluidreservoir sammelt sich bei Betrieb der Antriebsanordnung Fluid, in das zumindest das zweite Zahnrad eintaucht, um dem Kanal Fluid zuzuführen. Mit anderen Worten wird durch den Regulierungsabschnitt sichergestellt, dass ein Fluidstand in dem Fluidreservoir bei Betrieb der Antriebsanordnung stets so groß ist, dass das zweite Zahnrad zumindest teilweise in das Fluid eintaucht.In order to regulate the fluid supplied to the gear pump, the housing of the gear pump may include a regulating portion forming a fluid reservoir in fluid communication with a fluid sump in a housing of the transmission stands. During operation of the drive arrangement, fluid accumulates in the fluid reservoir into which at least the second gearwheel dips in order to supply fluid to the channel. In other words, it is ensured by the regulating section that a fluid level in the fluid reservoir during operation of the drive arrangement is always so great that the second gearwheel at least partially dips into the fluid.
Das Gehäuse der Zahnradpumpe kann ein Abdeckungsbauteil aufweisen, an dem das Gehäusebauteil und/oder der Regulierungsabschnitt angeordnet sind und das insbesondere – in axialer Richtung der Zahnräder gesehen – eine Stirnseite des Zahnradpumpengehäuses bildet. Das Abdeckungsbauteil kann beispielsweise eine Basis bilden, an der das Gehäusebauteil und der Regulierungsabschnitt separat voneinander befestigt, insbesondere verrastet sind.The housing of the gear pump can have a cover component, on which the housing component and / or the regulation section are arranged, and which, in particular-viewed in the axial direction of the gear wheels-forms an end face of the gear pump housing. The cover component may, for example, form a base on which the housing component and the regulating section are fastened separately from one another, in particular latched.
Gemäß einer Ausführungsform ist die Aggregateinheit eine elektrische Maschine, die als Motor und/oder als Generator betreibbar ist.According to one embodiment, the aggregate unit is an electric machine that can be operated as a motor and / or as a generator.
Weitere Ausführungsformen der Erfindung sind in der Beschreibung, den Zeichnungen und den Ansprüchen angegeben.Further embodiments of the invention are given in the description, the drawings and the claims.
