Description

Antriebsvorrichtunq für einen Kraftfahrzeuqantriebsstranq  Drive device for a motor vehicle drive train
Die vorliegende Erfindung bezieht sich auf eine Antriebsvorrichtung für einen Kraftfahrzeugantriebsstrang gemäß dem Oberbegriff von Patentanspruch 1 . The present invention relates to a drive device for a motor vehicle drive train according to the preamble of claim 1.
Eine gattungsgemäße Antriebsvorrichtung ist bereits beispielsweise mit der A generic drive device is already, for example, with the
EP 1 190 882 A1 bekannt geworden und umfasst ein als elektrische Maschine ausgebildetes und als Starter-Generator fungierendes Antriebsaggregat mit einem um eine Achse drehbar angeordneten Rotor und mit einem dazu unter Ausbildung eines radialen Luftspalts koaxial angeordneten Stator. Als elektromagnetische Rotorkomponente weist der Rotor der elektrischen Maschine ein Blechpaket mit einer Rotorwicklung auf, welches von einem Rotorträger aufgenommen ist, der wiederum an einem Gehäuse eines zu der elektrischen Maschine benachbarten Drehmomentwandlers festgelegt ist. Der Stator ist dabei an einem als Getriebegehäuseglocke vorliegenden Statorträger angeordnet, welcher an einem inneren Gehäusewandbereich, also rotorseitig eine elektromagnetische Statorkomponente in Form einer an einem Statorblechpaket angeordneten Statorwicklung trägt. Die elektrische Maschine ist somit als eine Innenläufermaschine ausgebildet. EP 1 190 882 A1 has become known and comprises a drive unit designed as an electric machine and functioning as a starter generator with a rotor rotatably mounted about an axis and with a stator arranged coaxially therewith to form a radial air gap. As an electromagnetic rotor component, the rotor of the electric machine has a laminated core with a rotor winding, which is received by a rotor carrier, which in turn is fixed to a housing of a torque converter adjacent to the electric machine. The stator is arranged on a stator carrier which is in the form of a gear housing bell, which carries an electromagnetic stator component in the form of a stator winding arranged on a stator lamination stack on an inner housing wall area, ie on the rotor side. The electric machine is thus designed as an internal rotor machine.
Zum Betreiben eines derartigen, üblicherweise als Drehfeldmaschine ausgeführten Starter-Generators in einem Kraftfahrzeugantriebsstrang ist eine Leistungselektronik erforderlich, welche die elektrische Maschine mit einem Strom bzw. einer Spannung variabler Frequenz und Amplitude speisen kann. Die Anordnung einer solchen zugehörigen Leistungselektronik ist in der EP 1 190 882 A1 zwar nicht beschrieben, jedoch kann davon ausgegangen werden, dass diese in einem Bereich außerhalb der dort dargestellten Getriebeglocke angeordnet ist. Sofern die elektrische Maschine auch zum zumindest zeitweisen Antreiben des Kraftfahrzeuges genutzt werden soll, ist zudem eine effektive Kühlung der elektrischen Maschine erforderlich. To operate such a starter-generator, which is usually designed as a rotating field machine, in a motor vehicle drive train, power electronics are required which can supply the electrical machine with a current or a voltage of variable frequency and amplitude. Although the arrangement of such an associated power electronics is not described in EP 1 190 882 A1, it can be assumed that it is arranged in an area outside the gearbox bell shown there. If the electric machine is also to be used for at least temporary driving of the motor vehicle, an effective cooling of the electric machine is also required.
Von diesem Stand der Technik ausgehend, liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine bauraumsparende Antriebsvorrichtung für einen Kraftfahrzeugantriebsstrang mit einer elektrischen Maschine und einer zugehörigen Leistungselektronik darzustellen. Diese Antriebsvorrichtung soll dabei zugleich zur effektiven Abfuhr einer beim Betreiben der elektrischen Maschine anfallenden Verlustwärme ausgebildet sein. Based on this prior art, the present invention has the object to represent a space-saving drive device for a motor vehicle drive train with an electric machine and an associated power electronics. This drive device is intended to be effective at the same time Removal be incurred in operating the electrical machine resulting heat loss.
Diese Aufgabe wird durch eine gattungsgemäße Antriebsvorrichtung mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den abhängigen Ansprüchen hervor. This object is achieved by a generic drive device with the characterizing features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the dependent claims.
Es wird demnach bei einer Antriebsvorrichtung der eingangs genannten Art vorgeschlagen, an dem Statorträger auf einer dem Rotor abgewandten Seite einen Aufnahmebereich auszubilden, von dem eine Elektronikbaugruppe, beispielsweise ein Maschinenumrichter, zum Ansteuern der elektrischen Maschine aufgenommen oder dort angeordnet ist. Des Weiteren soll dabei der Statorträger eine Fluid- Kühlanordnung aufweisen, welche mit der elektromagnetischen Statorkomponente und mit der Elektronikbaugruppe im Wärmeaustauschkontakt steht. It is therefore proposed in a drive device of the type mentioned to form on the stator on a side facing away from the rotor a receiving area from which an electronic assembly, such as a machine converter, is picked up for driving the electric machine or arranged there. Furthermore, the stator support should have a fluid cooling arrangement which is in heat exchange contact with the electromagnetic stator component and with the electronics module.
Der Wärmeaustauschkontakt kann erfolgen, indem ein zumindest mittelbarer Anlagekontakt zwischen der Elektronikbaugruppe, beispielsweise einem Bauelementgehäuse oder einem diesem zugeordneten Kühlkörper und einer Fläche des Statorträgers ausgebildet ist. Dabei können zwischen den genannten Elementen Wärmeübertragungsmittel zur Verbesserung des Wärmetransports, wie zum Beispiel eine Wärmeleitpaste oder wärmeleitende Folien oder Platten oder dergleichen sandwichartig eingelegt sein. The heat exchange contact can be made by an at least indirect contact contact between the electronic assembly, such as a component housing or a heat sink associated therewith and a surface of the stator is formed. In this case, between the elements mentioned heat transfer means for improving the heat transport, such as a thermal paste or thermally conductive films or plates or the like may be sandwiched.
Alternativ und/oder zusätzlich kann ein Wärmeaustauschkontakt auch durch Wärmestrahlung oder durch Konvektion der erwärmten Umgebungsluft, welche gegebenenfalls durch eine Lüfteranordnung erzwungen werden kann, stattfinden. Alternatively and / or additionally, a heat exchange contact can also take place by thermal radiation or by convection of the heated ambient air, which can optionally be forced by a fan arrangement.
Auf die vorgeschlagene Weise kann also eine der elektrischen Maschine zugeordnete Leistungselektronik mit der elektrischen Maschine als eine Baueinheit ausgeführt werden. Eine separate Kühlanordnung, wie diese bei einer von der elektrischen Maschine abgesetzten Leistungselektronik erforderlich ist, kann entfallen. Stattdessen werden die zu kühlende elektromagnetische Statorkomponente und die Elektronikbaugruppe einer Leistungselektronik gemeinsam am Statorträger angeordnet und können somit gleichzeitig gekühlt werden. Ebenso können bei der vorgeschlagenen Anordnung zwischen der elektrischen Maschine und der Leistungselektronik ansonsten vorsehbare und auf eine hohe Stromtragfähigkeit auszulegenden Leistungsanschlussverbinder entfallen. In the proposed manner, therefore, one of the electrical machine associated power electronics can be performed with the electric machine as a unit. A separate cooling arrangement, as required for a remote from the electrical machine power electronics, can be omitted. Instead, the electromagnetic stator component to be cooled and the electronic module of a power electronics are arranged together on the stator and can thus be cooled simultaneously. Likewise, in the proposed arrangement between the electric machine and the power electronics otherwise predictable and to be designed for a high current carrying capacity power connection connector omitted.
Die elektrische Maschine kann ungeachtet eines zugrundeliegenden Wirkprinzips konstruktiv grundsätzlich mit einem radialen oder einem axialen Luftspalt, beispielsweise als ein Außenläufer, Innenläufer oder ein Scheibenläufer ausgeführt sein. Eine Außenläuferbauweise und weiter insbesondere eine permanenterregte Synchronmaschine weisen besondere Vorteile auf, da die elektromagnetische Rotorkomponente einer solchen Maschine mit einer vergleichsweise geringen radialen Erstreckung realisiert werden kann. Zugleich kann der elektromagnetisch wirksame Luftspalt zwischen Rotor und Stator auf einem vergleichsweise großen Durchmesser angeordnet werden, wodurch die Maschine axial kurz bauend ausführbar ist und dabei dennoch ein hohes Drehmoment erreichen kann. Regardless of an underlying principle of operation, the electric machine can basically be constructed with a radial or an axial air gap, for example as an external rotor, internal rotor or a disk rotor. An external rotor construction and more particularly a permanent magnet synchronous machine have particular advantages, since the electromagnetic rotor component of such a machine can be realized with a comparatively small radial extent. At the same time, the electromagnetically effective air gap between the rotor and the stator can be arranged on a comparatively large diameter, whereby the machine can be designed to be of short axial construction while nevertheless achieving a high torque.
Bei einem radial zum Rotor innenliegenden Stator kann die Elektronikbaugruppe im Inneren der elektrischen Maschine aufgenommen werden. Bei umgekehrter Bauweise (Innenläufer) kann die Elektronikbaugruppe beispielsweise an der Außenseite am Statorträger platziert werden. Wenn in diesem Fall der Statorträger gleichzeitig ein Gehäuse der elektrischen Maschine ausbildet, so ist die Elektronikbaugruppe dabei auf der Gehäuseaußenseite festlegbar, was unter bestimmten Bedingungen für eine effektive Kühlung ebenfalls von Vorteil sein kann. In the case of a stator which is located radially to the rotor, the electronic assembly can be accommodated in the interior of the electrical machine. In reverse construction (internal rotor), the electronics module can be placed, for example, on the outside of the stator. In this case, if the stator carrier at the same time forms a housing of the electrical machine, then the electronic assembly is fixable on the outside of the housing, which under certain conditions may also be advantageous for effective cooling.
Gemäß einer Ausführungsform kann der Statorträger zur Ausbildung der Fluid- Kühlanordnung einen ersten Zylinderbereich mit einem sich in Umfangsrichtung erstreckenden ringförmigen Kanalabschnitt der Fluid-Kühlanordnung umfassen. Die elektromagnetische Statorkomponente und die Elektronikbaugruppe sind dabei zur Anordnung an der inneren und der äußeren Zylinderumfangsfläche vorgesehen. According to one embodiment, the stator support for forming the fluid cooling arrangement may comprise a first cylinder area with a circumferentially extending annular channel section of the fluid cooling arrangement. The electromagnetic stator component and the electronic assembly are provided for placement on the inner and outer cylinder peripheral surfaces.
Mit weiterem Vorteil kann der Statorträger einen Radialwandbereich umfassen, in welchem insbesondere sich in radialer Richtung erstreckende Kühlmittelzufuhr- und Kühlmittelabfuhrkanäle ausgebildet sind, welche einerseits mit einem Kühlmittelein- lassanschluss bzw. einem Kühlmittelauslassanschluss und andererseits mit dem vorgenannten ringförmigen Kanalabschnitt verbunden sind bzw. werden können. Der Radialwandbereich kann sich insbesondere bei einem Außenläufer radial über den ersten Zylinderbereich und im Weiteren sogar über den Stator hinaus erstreckenden und weitere Funktionalitäten aufweisen. In diesem Radialwandbereich können bedarfsweise weitere Kanalabschnitte ausgebildet sein, beispielsweise sich in Umgangsrichtung erstreckende Kanalabschnitte, womit an dem Radialwandbereich angeordnete elektronische Komponenten gezielt gekühlt werden können. With further advantage, the stator carrier can comprise a radial wall region in which, in particular, coolant supply and coolant discharge channels extending in the radial direction are formed, which on the one hand are connected to a coolant inlet. Lassanschluss or a Kühlmittelauslassanschluss and on the other hand are connected to the aforementioned annular channel section or can be. The radial wall region may, in particular in the case of an external rotor, extend radially beyond the first cylinder region and furthermore even beyond the stator and may have additional functionalities. If necessary, further channel sections may be formed in this radial wall area, for example channel sections extending in the circumferential direction, with which electronic components arranged on the radial wall area can be cooled in a targeted manner.
Gemäß einer Weiterbildung der Erfindung kann die elektrische Maschine im Antriebsstrang axial zwischen einer ersten und einer zweiten Drehmomentübertragungseinrichtung angeordnet sein, welche jeweils einen Eingangsbereich und einen Ausgangsbereich aufweisen. Dabei kann hinsichtlich eines Drehmomentflusses von der ersten zur zweiten Drehmomentübertragungseinrichtung der Rotor mit dem Eingangsbereich der ersten Drehmomentübertragungseinrichtung verbunden sein. Das bedeutet, dass die elektrische Maschine unter Zugrundelegung dieser Flussrichtung funktional somit vor der ersten und auch der zweiten Drehmomentübertragungseinrichtung angeordnet ist. Dieses Anordnungsprinzip kann Vorteile haben zum Beispiel bei der gemeinsamen Anordnung von der ersten Drehmomentübertragungseinrichtung und der elektrischen Maschine in einem im Innendurchmesser variierenden Aufnahmegehäuse. Zum Beispiel kann bei einem sich in der Anordnungsrichtung verjüngenden Gehäuse die erste Drehmomentübertragungseinrichtung mit einem vergleichsweise großen Durchmesser und großer Axiallänge in einem ersten Gehäuseabschnitt ausgeführt sein, während die dazu vergleichsweise axial kurz bauende und im Durchmesser zumindest näherungsweise entsprechende elektrische Maschine in einem zweiten Gehäuseabschnitt mit einer im Vergleich geringeren oder sich dort verringernden lichten Weite angeordnet sein kann. Mit weiterem Vorteil kann der Rotor der elektrischen Maschine lösbar, zum Beispiel mittels einer Schraubverbindung mit dem Eingangsbereich der ersten Drehmomentübertragungseinrichtung verbunden sein. Für eine erleichterte Montage kann die Verschraubungsachse bzw. eine Einführrichtung der Verbindungsmittel auch unter einem Winkel zwischen der Radial- und Axialrichtung angeordnet sein, wie dieses bei einer Schrägverschraubung der Fall ist. According to one development of the invention, the electric machine in the drive train can be arranged axially between a first and a second torque transmission device, which each have an input region and an output region. In this case, with regard to a torque flow from the first to the second torque transmission device, the rotor can be connected to the input region of the first torque transmission device. This means that the electric machine is thus functionally arranged on the basis of this flow direction in front of the first and also of the second torque transmission device. This arrangement principle may have advantages, for example, in the common arrangement of the first torque transmitting device and the electric machine in an inner diameter varying receiving housing. For example, in a tapered in the arrangement direction housing the first torque transmitting device with a comparatively large diameter and long axial length in a first housing section, while the comparatively axially short-building and diameter at least approximately corresponding electric machine in a second housing portion with a can be arranged in comparison with smaller or decreasing clear width. With further advantage, the rotor of the electric machine can be detachably connected, for example by means of a screw connection, to the input region of the first torque transmission device. To facilitate assembly, the screwing axis or an insertion direction of the connecting means can also be arranged at an angle between the radial and axial directions, as in the case of a helical screw connection the case is.
Der Rotor der elektrischen Maschine kann grundsätzlich mittels dessen Rotorträger separat an einer Welle oder an einem feststehenden Element der Antriebsvorrichtung gelagert werden. Gemäß einer vorteilhaften Variante wird vorgeschlagen, den Rotor mittels einem um eine Achse drehbar gelagerten Element der ersten Drehmomentübertragungseinrichtung zu lagern, was bedeutet, dass eine separate Rotorlagerung entfallen kann. In principle, the rotor of the electric machine can be mounted separately by means of its rotor carrier on a shaft or on a stationary element of the drive device. According to an advantageous variant, it is proposed to mount the rotor by means of a rotatably mounted about an axis element of the first torque transmitting device, which means that a separate rotor bearing can be omitted.
Ebenso kann der Stator an einem für die Elektromaschine gesondert vorliegenden Element, zum Beispiel an einem eigenem Statorgehäuse oder an einem Lagerschild der Elektromaschine festgelegt werden. Der Statorträger kann dabei gleichzeitig als Gehäuse ausgebildet sein. Es hat sich jedoch als vorteilhaft erwiesen, den Statorträger an einem Gehäuse der zu der elektrischen Maschine im Antriebsstrang benachbarten zweiten Drehmomentübertragungseinrichtung oder an einem Gehäuse einer weiteren Antriebstrangkomponente festzulegen. Likewise, the stator can be fixed to a separate element for the electric machine, for example on a separate stator housing or on a bearing plate of the electric machine. The stator can be simultaneously formed as a housing. However, it has proven advantageous to fix the stator carrier on a housing of the second torque transmission device adjacent to the electric machine in the drive train or on a housing of a further drive train component.
Wenn die Antriebsvorrichtung für ein Hybridfahrzeug vorgesehen ist, bei dem die elektrische Maschine das Fahrzeug allein oder im Verein mit einem zweiten Antriebsaggregat antreiben kann, ist es zweckmäßig, die erste Drehmomentübertragungseinrichtung als ein hydrodynamisches Koppelelement oder als eine Trennkupplung auszuführen. Insbesondere kann der Eingangsbereich der ersten Drehmomentübertragungseinrichtung als Gehäuse ausgebildet sein. Das Koppelelement bzw. Trennkupplung können als Anfahrelement dienen und zum Beispiel als ein hydrodynamischer Drehmomentwandler oder eine Reibungskupplung vorliegen. Alternativ kann die erste Drehmomentübertragungseinrichtung auch ein Torsionsdämpfer sein. If the drive device is provided for a hybrid vehicle, in which the electric machine can drive the vehicle alone or in conjunction with a second drive unit, it is expedient to carry out the first torque transmission device as a hydrodynamic coupling element or as a disconnect clutch. In particular, the input region of the first torque transmission device may be formed as a housing. The coupling element or separating clutch can serve as a starting element and be present for example as a hydrodynamic torque converter or a friction clutch. Alternatively, the first torque transmitting device may also be a torsion damper.
Darauf aufbauend kann die zweite Drehmomentübertragungseinrichtung als ein Getriebe ausgebildet sein, beispielsweise als ein Wechselgetriebe oder ein Automatgetriebe. Based on this, the second torque transmission device can be designed as a transmission, for example as a change gear or an automatic transmission.
Zur Darstellung einer Hybrid-Antriebsvorrichtung kann der Eingangsbereich der ersten Drehmomentübertragungseinrichtung mit einer Abtriebswelle eines als Verbren- nungsmotor ausgebildeten zweiten Antriebsaggregats in Drehmomentübertragungsverbindung stehen oder gebracht werden. In order to illustrate a hybrid drive device, the input region of the first torque transmission device can be connected to an output shaft of a combustion engine as a combustion engine. tion engine formed second drive unit are in torque transmission connection or brought.
Zur Erzielung einer besonders kompakten Bauweise kann es vorteilhaft sein, den Radialwandbereich des Statorträgers an der einem Verbindungsbereich des Rotors mit der ersten Drehmomentübertragungseinrichtung gegenüberliegenden Axialseite der elektrischen Maschine auszuführen. In order to achieve a particularly compact design, it may be advantageous to design the radial wall region of the stator carrier on the axial side of the electric machine opposite a connection region of the rotor with the first torque transmission device.
In diesem Sinne ist es auch vorteilhaft, den Aufnahmebereich zur Anordnung der Elektronikbaugruppe zumindest abschnittweise als in den Stator axial hineinreichenden Ringraum mit einer Zentralausnehmung auszubilden. Dieser Ringraum wird damit zumindest durch den ersten Zylinderbereich der Fluid-Kühlanordnung begrenzt. Weiterhin kann ein Bodenbereich und ein von dem ersten Zylinderbereich radial beabstandet ausgebildeter zweiter Zylinderbereich vorliegen. In noch weiterer Ausgestaltung kann der Ringraum einseitig oder beidseitig durch jeweils ein Deckelelement, insbesondere fluiddicht verschlossen sein. Die vorhandene Zentralausnehmung kann eine Antriebswellendurchführung ausbilden, durch welche zum Beispiel eine Getriebeeingangswelle zumindest teilweise durchführbar ist. In this sense, it is also advantageous to form the receiving area for the arrangement of the electronic assembly at least in sections as axially extending into the stator annulus with a central recess. This annular space is thus limited at least by the first cylinder region of the fluid-cooling arrangement. Furthermore, a bottom region and a second cylinder region formed radially spaced from the first cylinder region may be present. In yet a further embodiment, the annular space can be closed on one or both sides by a respective cover element, in particular in a fluid-tight manner. The existing central recess may form a drive shaft bushing, through which, for example, a transmission input shaft is at least partially feasible.
Sofern die elektromagnetische Statorkomponente ein Blechpaket und eine Statorwicklung mit Wicklungsenden aufweist, wird vorgeschlagen, den Statorträger mit einem zu den Wicklungsenden benachbarten Wandabschnitt mit Gehäusedurchbrüchen auszubilden, durch welchen die Wicklungsenden hindurchgeführt und auf der der Wicklung, insbesondere den Spulen abgewandten Seite mit einem Schaltungsträger verbunden werden können. Der Schaltungsträger kann dazu eine Tragestruktur mit darauf angeordneten elektrischen Verbindungsleitern in Form von Leiterbahnen und/oder anderen Leiterelementen aufweisen. Der Schaltungsträger kann in weiterer Ausgestaltung die im Aufnahmeraum angeordnete Elektronikbaugruppe bzw. deren einzelnen elektronischen Bauelemente tragen und diese elektrisch mit den Spulenenden verbinden. Der Schaltungsträger kann bevorzugt innerhalb eines Aufnahmeraums des Statorträgers angeordnet und fluiddicht verschlossen sein. Auf diese Weise stellt der Statorträger ein Gehäuse des Schaltungsträgers dar. Wie bereits vorher angesprochen, kann zur Erzielung eines hohen Antriebsdrehmoments der elektrischen Maschine der Rotor mit weiterem Vorteil einen Außendurchmesser aufweisen, welcher etwa dem Außendurchmesser der ersten Drehmomentübertragungseinrichtung entspricht. Bei einer schmalen radialen Bauform des Rotors kann der radiale Luftspaltdurchmesser der elektrischen Maschine somit näherungsweise dem maximalen Durchmesser der ersten Drehmomentübertragungseinrichtung entsprechen. If the electromagnetic stator component has a laminated core and a stator winding with winding ends, it is proposed to form the stator carrier with a wall section adjacent to the winding ends with housing openings through which the winding ends are passed and connected to a circuit carrier on the side facing away from the winding, in particular the coils can. For this purpose, the circuit carrier can have a carrying structure with electrical connecting conductors in the form of printed conductors and / or other conductor elements arranged thereon. In a further refinement, the circuit carrier can carry the electronic assembly or its individual electronic components arranged in the receiving space and electrically connect them to the coil ends. The circuit carrier may preferably be arranged within a receiving space of the stator and sealed fluid-tight. In this way, the stator carrier is a housing of the circuit substrate. As already mentioned above, in order to achieve a high driving torque of the electric machine, the rotor may, with further advantage, have an outer diameter which corresponds approximately to the outer diameter of the first torque transmission device. With a narrow radial design of the rotor, the radial air gap diameter of the electric machine can thus correspond approximately to the maximum diameter of the first torque transmission device.
Zur optimierten Ansteuerung der elektrischen Maschine kann zur Erfassung einer Drehwinkellage des Rotors ein Drehstellungsgeber mit zumindest einem Sensor und mit einer Geberspur vorgesehen sein. Es wird diesbezüglich vorgeschlagen, den Sensor als Element der Elektronikbaugruppe auszubilden und diesen somit gleichfalls auf dem Schaltungsträger anzuordnen und zu kontaktieren. Die Geberspur kann am Rotor oder an einem mit diesem drehfest verbundenen Element, beispielsweise dem Eingangsbereich der ersten Drehmomentübertragungseinrichtung, insbesondere einem Gehäusebereich angeordnet werden. For optimized control of the electric machine can be provided with at least one sensor and with a donor track for detecting a rotational angular position of the rotor, a rotary encoder. It is proposed in this regard to form the sensor as an element of the electronic assembly and thus also to arrange this on the circuit board and to contact. The encoder track can be arranged on the rotor or on an element connected to it in a rotationally fixed manner, for example the input area of the first torque transmission device, in particular a housing area.
Nachfolgend wird die Erfindung anhand einer in der beigefügten Figur dargestellten Ausführungsform beispielhaft erläutert. The invention will be explained by way of example with reference to an embodiment shown in the attached figure.
Die einzige Figur zeigt eine Antriebsvorrichtung 10 für einen Kraftfahrzeugantriebsstrang eines Hybridfahrzeugs in einer schematischen Darstellung. The single FIGURE shows a drive device 10 for a motor vehicle drive train of a hybrid vehicle in a schematic representation.
Die dargestellte Antriebsvorrichtung 10 umfasst zunächst ein Automatgetriebe 12 mit einem Getriebegehäuse 12a und ein in einer diesem zugehörigen Gehäuseglocke 12b angeordnetes erstes, als elektrische Maschine 14 ausgebildetes Antriebsaggregat 140 mit einem um eine Achse A drehbar angeordneten Rotor 1 6 und mit einem dazu unter Ausbildung eines radialen Luftspalts 18 koaxial und radial innen dazu angeordneten Stator 20. Somit ist die elektrische Maschine 14 vorliegend als ein Außenläufer aufgebaut. The illustrated drive device 10 initially comprises an automatic transmission 12 with a transmission housing 12a and a first associated with this bell housing 12b first, designed as an electric machine 14 drive unit 140 with a rotatable about an axis A arranged rotor 1 6 and with a thereto to form a radial Air gap 18 coaxially and radially inside arranged stator 20. Thus, the electric machine 14 is constructed here as an external rotor.
Der Rotor 1 6 weist einen Rotorträger 1 6a auf, an welchem ein Rotorblechpaket 1 6b mit zum Stator 20 ausgerichteten Permanentmagneten 1 6c angeordnet ist, wobei das Blechpaket 1 6b und die Permanentmagnete 1 6c als elektromagnetische Rotorkomponente 1 60 wirksam sind. Der Stator 20 weist einen beispielsweise aus einem Aluminiumwerkstoff hergestellten Statorträger 24 mit einer insgesamt topfförmigen Gestalt auf. Ein hohl ausgeführter erster Zylinderbereich 24a des Statorträgers 22 nimmt mit dessen zum Rotor 1 6 zugewandten Außenumfangsfläche 24b drehfest ein Statorblechpaket 26 mit Zähnen und Nuten auf, an dem wiederum eine Statorwicklung 28 in Form von Zahnspulen 28 festgelegt ist. Die Zahnspulen 28 weisen Wicklungsenden 29 auf, die in einer unten beschriebenen Art und Weise verschaltet werden. Das Statorblechpaket 26 und die Zahnspulen 28 bilden ihrerseits eine elektromagnetische Statorkomponente 280 aus, welche somit über die Außenumfangsfläche 24b des Statorträgers 24 im Wärmeaustausch treten können. The rotor 1 6 has a rotor support 1 6a, on which a rotor laminated core 1 6b is arranged with the stator 20 aligned permanent magnet 1 6c, wherein the laminated core 1 6b and the permanent magnets 1 6c as electromagnetic rotor component 1 60 are effective. The stator 20 has a stator carrier 24, which is made, for example, from an aluminum material and has an overall pot-shaped form. A hollow executed first cylinder portion 24a of the stator 22 takes with its rotor 6 to the outer peripheral surface 24b rotatably on a stator lamination 26 with teeth and grooves on which in turn a stator winding 28 is set in the form of tooth coils 28. The toothed coils 28 have winding ends 29 which are connected in a manner described below. The laminated stator core 26 and the toothed coils 28 in turn form an electromagnetic stator component 280, which can thus heat exchange over the outer circumferential surface 24b of the stator support 24.
Im Inneren des Statorträgers 24 ist ein sich in Umfangsrichtung erstreckender ringförmigen Kanalabschnitt 30a ausgebildet, der Teil einer Fluid-Kühlanordnung 30 zum Kühlen der elektromagnetischen Statorkomponente 280 ist. Inside the stator support 24, there is formed a circumferentially extending annular channel portion 30a which is part of a fluid cooling assembly 30 for cooling the stator electromagnetic component 280.
Auf der dem Rotor 16 abgewandten Seite des ersten Zylinderbereichs 24a, also im Zylinderinnenraum ist ein radial innerer, erster Aufnahmebereich 24d vorgesehen, welcher als Ringraum 24d zumindest abschnittweise in den Stator 20 axial hineinreicht und im Bereich der Mittelachse A eine Zentralausnehmung 24e ausbildet. Der Aufnahmebereich 24d wird in diesem Bereich durch den ersten Zylinderbereich 24a der Fluid-Kühlanordnung 30 begrenzt. Zur weiteren Begrenzung des Aufnahmebereichs 24d dienen ein von dem ersten Zylinderbereich 24a radial beabstandeter zweiter Zylinderbereich 24f und ein zwischen den Zylinderbereichen 24a, f angeordneter Bodenbereich 24g. In dem Ringraum 24d ist eine Elektronikbaugruppe 32, insbesondere elektronische Bauelemente eines Maschinenumrichters zum Ansteuern der elektrischen Maschine 14 eingesetzt, die über die Innenumfangsfläche 24c des ersten Zylinderbereichs 24a mit der Fluid-Kühlanordnung 30 im Wärmeaustauschkontakt steht. Insbesondere stehen die elektronischen Bauelemente, wie Kondensatoren und Leistungshalbleiter, mit dem Statorträger im Wärmeleitungskontakt. Dazu ist zwischen diesen Bauelementen und dem Statorträger 24 ein gut wärmeleitendes und gleichzeitig elektrisch isolierendes Mittel, insbesondere ein bekannter gap filier, ein- gebracht. Dieser kann als formbare Knetmasse oder als Matte lückenüberbrückend in vorhandene Zwischenräume eingefügt werden. On the side facing away from the rotor 16 of the first cylinder portion 24a, ie in the cylinder interior, a radially inner, first receiving portion 24d is provided which at least partially extends axially into the stator 20 as an annular space 24d and forms a central recess 24e in the region of the center axis A. The receiving area 24 d is limited in this area by the first cylinder area 24 a of the fluid cooling arrangement 30. For further delimitation of the receiving region 24d, a second cylinder region 24f radially spaced from the first cylinder region 24a and a bottom region 24g arranged between the cylinder regions 24a, f serve. In the annular space 24d, an electronic assembly 32, in particular electronic components of a machine converter for driving the electric machine 14 is used, which stands on the inner peripheral surface 24c of the first cylinder portion 24a with the fluid cooling arrangement 30 in heat exchange contact. In particular, the electronic components, such as capacitors and power semiconductors, with the stator in the heat conduction contact. For this purpose, between these components and the stator carrier 24 a good heat-conducting and at the same time electrically insulating means, in particular a known gap filier, a brought. This can be inserted as a moldable putty or as a mat gap-bridging in existing spaces.
Im Weiteren umfasst der Statorträger 24 einen sich bei dem dargestellten Außenläufer radial über den ersten Zylinderbereich 24a und vorliegend auch über die elektromagnetische Statorkomponente 280 hinaus erstreckenden Radialwandbereich 24h, in welchem ein sich in radialer Richtung erstreckender Kühlmittelzufuhrkanal 30b und ein Kühlmittelabfuhrkanal 30c ausgebildet sind, die einerseits mit einem am Getriebegehäuse 12a vorgesehenen Kühlmitteleinlassanschluss 30d und einem Kühlmit- telauslassanschluss 30e und andererseits mit dem ringförmigen Kanalabschnitt 30a verbunden sind und in Fluidverbindung stehen. Furthermore, the stator carrier 24 comprises a radial wall region 24h which extends radially beyond the first cylinder region 24a and in the present case also beyond the electromagnetic stator component 280 in the illustrated external rotor, in which a coolant supply channel 30b extending in the radial direction and a coolant discharge channel 30c are formed, on the one hand with a coolant inlet port 30d provided on the transmission housing 12a and a coolant outlet port 30e and on the other hand with the annular channel section 30a and in fluid communication.
In der Figur ist erkennbar, dass die elektrische Maschine 14 im Antriebsstrang axial zwischen einer ersten Drehmomentübertragungseinrichtung 34, die hier als ein an sich bekannter hydrodynamischer Drehmomentwandler 36 vorliegt und dem Automatgetriebe 12 angeordnet ist, welches eine zweite Drehmomentübertragungseinrichtung 38 darstellt. Jedes der beiden genannten Drehmomentübertragungseinrichtungen 34, 38 weist jeweils einen Eingangsbereich 34a, 38a und einen Ausgangsbereich 34b, 38b auf. Der Eingangsbereich 34a des hydrodynamischen Drehmomentwandlers 36 wird durch ein Wandlergehäuse 36a und ein damit verbundenes Pumenpenrad 36b gebildet, während der Ausgangsbereich 34b als ein Turbinenrad 36c ausgestaltet ist. Der Eingangsbereich 38a des Automatgetriebes 12 wird in üblicher weise durch eine Getriebeeingangswelle 12c gebildet, welche durch die Zentralausnehmung 24e des Statorträgers 24 hindurchgeführt ist, während der Ausgangsbereich 38b durch eine Getriebeausgangswelle 12d realisiert ist. In the figure, it can be seen that the electric machine 14 in the drive train extends axially between a first torque transmission device 34, which is present here as a known hydrodynamic torque converter 36 and the automatic transmission 12, which constitutes a second torque transmission device 38. Each of the two torque transmission devices 34, 38 has an input region 34a, 38a and an output region 34b, 38b. The input portion 34a of the hydrodynamic torque converter 36 is formed by a converter housing 36a and a pommel wheel 36b connected thereto, while the output portion 34b is configured as a turbine wheel 36c. The input portion 38a of the automatic transmission 12 is formed in the usual way by a transmission input shaft 12c, which is passed through the central recess 24e of the stator 24, while the output portion 38b is realized by a transmission output shaft 12d.
Hinsichtlich eines Drehmomentflusses von der ersten zur zweiten Drehmomentübertragungseinrichtung 34, 38 ist der Rotorträger 1 6a der elektrischen Maschine 14 mit Verbindungsmitteln 17, insbesondere mittels einer Verschraubung mit dem Eingangsbereich 34a der ersten Drehmomentübertragungseinrichtung 34, insbesondere lösbar mit dem Gehäuse 36a des hydrodynamischen Wandlers 36 verbunden, welche dazu ein Flanschelement 19 aufweist. Somit ist die die elektrische Maschine 14 unter Zugrundelegung dieser Flussrichtung funktional vor der ersten 34 und zweiten Drehmomentübertragungseinrichtung 38 angeordnet. Darüber hinaus ist der Rotor 1 6 auch mittels des um die Achse A drehbar gelagerten Gehäuses 36a an dem hydrodynamischen Drehmomentwandler 36 gelagert. Der hydrodynamische Drehmomentwandler 36 umfasst weiter ein Leitrad 34d und eine zwischen dem Eingangsbereich 34a und dem Ausgangsbereich 34b angeordnete Überbrückungskupp- lung 34c, welche in Abhängigkeit vom Fahrzustand aktiviert, das heißt geschlossen werden kann. With regard to a torque flow from the first to the second torque transmission device 34, 38, the rotor carrier 16a of the electric machine 14 is connected to connecting means 17, in particular detachably connected to the housing 36a of the hydrodynamic converter 36, in particular by means of a screw connection to the input region 34a of the first torque transmission device 34. which has a flange 19. Thus, the electric machine 14 is functionally ahead of the first 34 and second on the basis of this flow direction Torque transmitting device 38 is arranged. In addition, the rotor 16 is also mounted on the hydrodynamic torque converter 36 by means of the housing 36a mounted rotatably about the axis A. The hydrodynamic torque converter 36 further comprises a stator 34d and a lock-up clutch 34c arranged between the input area 34a and the output area 34b, which can be activated, that is to say closed, depending on the driving state.
Wie weiter erkennbar, ist der Statorträger 24 am Gehäuse 12a der zu der elektrischen Maschine 14 im Antriebsstrang benachbarten zweiten Drehmomentübertragungseinrichtung 38 festgelegt, was beispielsweise durch Befestigungsmittel 40, insbesondere als Verschraubung mittels Schraubbolzen an einer lateralen Getriebegehäusewandung 121 a erfolgen kann. Zu diesem Zweck kann ein außerhalb der Fluid- Kühlanordnung 30 liegender Bereich des Statorträgers 24, zum Beispiel der radial außenliegende Radialwandbereich 24h, der Bodenbereich 24g oder der zweite Zylinderbereich 24f genutzt werden. Zur Ermöglichung einer leichten Montage und der definierten Festlegung der elektrischen Maschine 14 können an dem Getriebegehäuse 12a, insbesondere an der lateralen Getriebewandung 121 a Zentriermittel, zum Beispiel in Form einer Zentrierplatte vorgesehen sein. As can be further seen, the stator support 24 is fixed to the housing 12a of the adjacent to the electric machine 14 in the drive train second torque transmitting device 38, which can be done for example by fastening means 40, in particular as a screw by means of bolts on a lateral gear housing wall 121 a. For this purpose, an area of the stator carrier 24 lying outside the fluid cooling arrangement 30, for example the radially outer radial wall area 24h, the floor area 24g or the second cylinder area 24f can be used. To enable easy assembly and the defined definition of the electric machine 14 may be provided on the transmission housing 12a, in particular on the lateral transmission wall 121 a centering, for example in the form of a centering plate.
Vorliegend ist der Radialwandbereich 24h des Statorträgers 24 bauraumsparend an der dem Verbindungsbereich des Rotors 1 6 mit dem hydrodynamischen Drehmomentwandler 36 gegenüberliegenden Axialseite der elektrischen Maschine 14 ausgeführt. Die Kühlmittelzufuhr- und abfuhrkanäle 30b, 30c können anstelle in dem Radialwandbereich 24h auch in der lateralen Getriebewandung 121 a ausgeführt sein. In the present case, the radial wall region 24h of the stator carrier 24 is designed to save space on the axial side of the electric machine 14 opposite the connection region of the rotor 16 with the hydrodynamic torque converter 36. The coolant supply and discharge channels 30b, 30c may also be embodied in the lateral transmission wall 121a instead of in the radial wall area 24h.
Der vorgenannte Radialwandbereich 24h ist zudem axial benachbart zu den Zahnspulen 28 angeordnet, wobei deren Wicklungs- bzw. Spulenenden 29 durch in den Radialwandbereich 24h eingebrachte Gehäusedurchbrüche 241 h axial in Richtung des Automatgetriebes 12 hindurchgeführt und auf der den Spulen 28 abgewandten Seite mit einem Schaltungsträger 42 verbunden sind, welcher gleichfalls die Elektronikbaugruppe 32, also die Bauelemente des Maschinenumrichters trägt und diese sowohl miteinander als auch mit den Spulenenden 29 elektrisch verschaltet. In der Darstellung ist ein Gehäusedurchbruch 241 h vereinfacht in einer mit den Kühlmittelzufuhr- und abfuhrkanälen 30b, 30c zusammenfallenden Schnittebene gezeigt, welche für den Fachmann leicht erkennbar in der Realität in unterschiedlichen Umfangs- lagen und sich nicht gegenseitig durchdringend ausgebildet sind. The aforementioned radial wall area 24h is also arranged axially adjacent to the toothed coils 28, with their winding or coil ends 29 being guided axially into the direction of the automatic transmission 12 through housing openings 241h introduced into the radial wall area 24h and to a circuit carrier 42 on the side facing away from the coils 28 are connected, which also carries the electronic assembly 32, so the components of the machine converter and electrically interconnected with each other and with the coil ends 29. In the Representation is a housing opening 241 h shown simplified in a coincident with the coolant supply and discharge channels 30b, 30c cutting plane, which are easily recognizable to those skilled in reality in different circumferential layers and are not mutually penetrating.
Der Schaltungsträger 42 ist in einem am Statorträger 24 stirnseitigen und im Ausführungsbeispiel von der Getriebeseite zur Montage offenen, radial äußeren, zweiten Aufnahmebereich 24i eingesetzt, welcher sich an den radial inneren bzw. ersten Aufnahmebereich 24d anschließt. Zur Bildung des ersten und des zweiten Aufnahmebereichs 24d; 24i ist am Statorträger 24 eine im Innendurchmesser gestufte Ausnehmung 24k ausgeführt, welche sich auf der Seite der Spulenenden 29 zur Aufnahme des Schaltungsträgers 42 erweitert. Der Statorträger 24 stellt damit ein Aufnahmegehäuse des Schaltungsträgers 42 dar. Der somit vorliegende gesamte Aufnahmebereich 24d, 24i ist, insbesondere fluiddicht durch ein Deckelelement 44 verschlossen. Das Deckelelement 44ist hierzu am Statorträger 24 festgelegt, alternativ kann dieses auch am Getriebegehäuse 12a festgelegt werden. Das Deckelelement 44 besteht vorzugsweise aus einem Werkstoff mit einer, insbesondere gegenüber dem Statorträger 24 und dem Getriebegehäuse12a, geringeren Wärmeleitfähigkeit. Zum Beispiel kann das Deckelelement 44 aus einem in der gezeigten Einbauumgebung hinsichtlich der dort eintretenden Betriebstemperaturen widerstandsfähigen, das heißt temperaturfesten Kunststoff, zum Beispiel einem glasfaserverstärkten Kunststoff (GFK) ausgebildet sein. Das Deckelement dient neben dem Verschließen der Elektronikbaugruppe 32, bzw. des Aufnahmebereichs 24d, 24i damit auch zur thermischen Abschirmung der Elektronikbaugruppe 32 mit dem Schaltungsträger 42 gegenüber einem Wärmeeintrag des benachbarten im Betriebszustand auf einer hohen Temperatur befindlichen Getriebes 12. The circuit carrier 42 is inserted in a front side on the stator support 24 and in the embodiment of the transmission side for mounting open, radially outer, second receiving portion 24i, which adjoins the radially inner and first receiving portion 24d. To form the first and second receiving areas 24d; 24i is performed on the stator 24 a stepped inside diameter recess 24k, which widens on the side of the coil ends 29 for receiving the circuit substrate 42. The stator carrier 24 thus constitutes a receiving housing of the circuit carrier 42. The entire receiving area 24d, 24i thus present is, in particular, sealed in a fluid-tight manner by a cover element 44. For this purpose, the cover element 44 is fixed to the stator carrier 24; alternatively, this can also be fixed to the transmission housing 12a. The cover element 44 preferably consists of a material with a, in particular with respect to the stator 24 and the Getriebegehäusea, lower thermal conductivity. For example, the cover element 44 can be made of a plastic, for example a glass-fiber-reinforced plastic (GRP), that is resistant to heat, ie temperature-resistant, in the installation environment shown there. The cover element is used in addition to closing the electronic assembly 32, or the receiving area 24d, 24i so that the thermal shielding of the electronic assembly 32 to the circuit substrate 42 against heat input of the adjacent in the operating state at a high temperature transmission 12th
Zur phasengerechten Ansteuerung der Statorwicklung 28 in Abhängigkeit von der Drehwinkellage des Rotors 16 weist die Elektronikbaugruppe 32 einen kontaktlos arbeitenden Drehstellungsgeber 47 auf. Dieser umfasst zumindest einen auf dem Schaltungsträger 42 angeordneten und bezüglich des Rotors 1 6 feststehenden Sensor 48, insbesondere einen induktiven Sensor, wie einen Hallsensor oder einen Wirbelstromsensor sowie eine sich mit dem Rotor 1 6 drehende Geberspur 50. Vorlie- gend ist im Statorträger 24 eine sich in Richtung der Geberspur 50 erstreckende Durchgriffsöffnung 52 ausgebildet, durch welche der Sensor 48 hindurch ein Stellungssignal der Geberspur 50 abgreifen kann. Im Ausführungsbeispiel ist dazu der Sensor 48 abgedichtet und zumindest teilweise durchgreifend in der Durchgriffsöffnung 52 angeordnet, um räumlich der Sensorspur 50 möglichst nahe zu sein. Die Geberspur 50 ist als eine Geberscheibe mit einer periodischen Zahn-Lücke- Konfiguration ausgebildet und wie auch der Rotor 1 6 fest mit dem Eingangsbereich 34a der ersten Drehmomentübertragungseinrichtung, also dem Wandlergehäuse 36a verbunden. In Abhängigkeit von der konstruktiven Ausgestaltung der Antriebsvorrichtung 10 kann die Geberspur 50 wahlweise auch am Rotor 1 6 selbst ausgebildet sein. Zur Erhöhung der Messgenauigkeit können auch mehrere Sensoren 48 vorhanden sein, welche in diesem Fall zur Abtastung der Geberspur 50 auf einem gemeinsamen Teilkreis um die Drehachse des Rotors 1 6 angeordnet werden können. For phase-controlled control of the stator winding 28 as a function of the angular position of the rotor 16, the electronic assembly 32 has a non-contact rotary position sensor 47. This comprises at least one arranged on the circuit substrate 42 and with respect to the rotor 1 6 stationary sensor 48, in particular an inductive sensor, such as a Hall sensor or an eddy current sensor and a rotatable with the rotor 1 6 encoder track 50th vorlie- In the stator carrier 24, a passage opening 52 extending in the direction of the encoder track 50 is formed, through which the sensor 48 can pick off a position signal of the encoder track 50. In the exemplary embodiment, the sensor 48 is sealed for this purpose and arranged at least partially penetrating in the through-opening 52 in order to be as close as possible to the sensor track 50. The encoder track 50 is formed as a donor disk with a periodic tooth-gap configuration and as well as the rotor 1 6 fixed to the input portion 34 a of the first torque transmitting device, ie the converter housing 36 a connected. Depending on the structural design of the drive device 10, the encoder track 50 may optionally also be formed on the rotor 1 6 itself. To increase the accuracy of measurement, it is also possible for a plurality of sensors 48 to be present, which in this case can be arranged for scanning the encoder track 50 on a common pitch circle about the axis of rotation of the rotor 16.
Es ist ferner erkennbar, dass der Rotor 1 6 einen Außendurchmesser aufweist, welcher etwa dem Außendurchmesser der ersten Drehmomentübertragungseinrichtung 34 entspricht. Bei der erläuterten Bauweise der elektrischen Maschine 14 als permanenterregte Außenläufermaschine entspricht der radiale Luftspaltdurchmesser näherungsweise dem Außendurchmesser des hydrodynamischen Drehmomentwandlers 36. It can also be seen that the rotor 1 6 has an outer diameter which corresponds approximately to the outer diameter of the first torque transmission device 34. In the described construction of the electric machine 14 as a permanently excited external rotor machine, the radial air gap diameter approximately corresponds to the outside diameter of the hydrodynamic torque converter 36.
Zur Bildung eines Hybridantriebs steht der Eingangsbereich 34a des hydrodynamischen Drehmomentwandlers 36 mit einer als Kurbelwelle vorliegenden Abtriebswelle 46a eines als Verbrennungsmotor 46 ausgebildeten zweiten Antriebsaggregats 142 in Drehmomentübertragungsverbindung, wobei weitere Antriebsstrangelemente funktional zwischengeschaltet sein können. Bezuqszeichen To form a hybrid drive, the input region 34a of the hydrodynamic torque converter 36 is in torque transmission connection with an output shaft 46a of a second drive unit 142 in the form of a crankshaft, wherein further drive train elements may be functionally interposed.
