Description

Die Erfindung betrifft ein Fahrzeug mit Längsmotor und permanenten Vorderachsantrieb, das einen Verbrennungsmotor und eine elektrische Maschine aufweist, wobei ein Modul Antriebsmomente bedarfsgerecht auf zwei Antriebsachsen verteilt.The invention relates to a vehicle with a longitudinal engine and permanent Vorderachsantrieb comprising an internal combustion engine and an electric machine, wherein a module distributed drive torque as needed on two drive axles.

Stand der TechnikState of the art

Auf Grund strikterer Anforderungen der Abgasnormen für PKWs ist es erforderlich, insbesondere bei allradgetriebenen Fahrzeugen, effizienzsteigernde Maßnahmen umzusetzen.Due to stricter requirements of the exhaust gas standards for passenger cars, it is necessary to implement efficiency-increasing measures, in particular for all-wheel drive vehicles.

Der zusätzliche Kraftstoffverbrauch, und die daraus entstehende Abgaserhöhung, von allradgetriebenen Fahrzeugen kann durch Abschalten der Allradfähigkeit eingeschränkt werden. Bei aktuellen Lösungen, z.B. reibkupplungsbasierende Moduln, wird dies durch komplettes Öffnen der Reiblamellenkupplung realisiert. Viele Premium-Fahrzeughersteller setzen aus Gründen der Fahrdynamik auf Allradantrieb.
Bisher bekannte Systeme, die auf der Technologie von Reiblamellenkupplungen basieren, können voll variabel gesteuert werden und eine Drehmomentverteilung von 0% bis 100% an eine Sekundärachse bereitstellen. Allradsysteme, die auf Reiblamellenkupplungen basieren, haben den Nachteil, dass auftretende Drehzahldifferenzen an den Achsen Einfluss auf das absetzbare Drehmoment an der Sekundärachse haben. Bei vollem Lenkeinschlag auf hohem Reibwert ist die Drehmomentverteilung begrenzt, da der kinematische Reifenschlupf zwischen den Achsen an der Reiblamellenkupplung ebenso durch Schlupf in der Reiblamellenkupplung erlaubt werden muss.The additional fuel consumption, and the resulting increase in exhaust gas, of all-wheel drive vehicles can be limited by switching off the all-wheel capability. In current solutions, such as friction clutch-based modules, this is achieved by completely opening the Reiblamellenkupplung. Many premium vehicle manufacturers rely on four-wheel drive for reasons of driving dynamics.
Previously known systems based on the technology of friction disk clutches can be fully variably controlled and provide a torque distribution of 0% to 100% to a secondary axle. Four-wheel systems based on friction disk clutches have the disadvantage that occurring speed differences on the axles have an influence on the settable torque on the secondary axle. At full steering angle on a high coefficient of friction, the torque distribution is limited, since the kinematic tire slip between the axles on the Reiblamellenkupplung must also be allowed by slippage in the Reiblamellenkupplung.

Alternativ werden auch Zentraldifferenziale eingesetzt. Diese haben eine fixe Drehmomentverteilung zwischen Vorder- und Hinterachse. Ein Vorteil bei Zentraldifferenzialen ist, dass das Drehmoment auch bei kinematischem Schlupf richtig verteilt werden kann.Alternatively, central differentials are used. These have a fixed torque distribution between the front and rear axles. An advantage with central differential is that the torque can be distributed even with kinematic slippage.

Die Anforderungen „rein elektrisches Fahren“ sowie Rekuperationspotential im Zyklus stellen konkurrierende Anforderungen. Für rein elektrisches Fahren ist ein hohes Drehmoment von ca. 1200 Nm auf Achsniveau erforderlich. Dieses Drehmoment kann durch eine entsprechend hohe Übersetzung zwischen Achse und einer elektrischen Maschine erreicht werden.The requirements of "purely electric driving" and recuperation potential in the cycle make competing demands. For purely electric driving, a high torque of approx. 1200 Nm at the axle level is required. This torque can be achieved by a correspondingly high ratio between the axis and an electric machine.

Dem gegenüber steht die Anforderung möglichst viel Energie im Fahrzyklus durch Umwandlung kinetischer Bremsenergie in elektrische Energie zu rekuperieren sowie möglichst niedrige Schleppverluste in der Leistungsmechanik und in der elektrischen Maschine zu generieren. Eine hohe Übersetzung die für „rein elektrisches Fahren“ benötigt wird, bringt die Schleppverluste in der Leistungsmechanik und in der elektrischen Maschine auf ein Niveau, welches das System hinsichtlich CO2 Verbesserung unattraktiv macht.In contrast, the requirement is to recuperate as much energy as possible in the drive cycle by converting kinetic braking energy into electrical energy and to generate the lowest possible drag losses in power mechanics and in the electrical machine. A high gear ratio required for "purely electric driving" brings the drag losses in power mechanics and in the electric machine to a level that makes the system unattractive in terms of CO2 improvement.

Aus der DE 103 196 81 A1 ist ein Modul für einen hybriden Allradantrieb bekannt. Dabei wird ein Modul mit mindestens drei Wellen vorgesehen, das als Summiergetriebe ausgebildet ist. Dabei wird die Antriebsleistung zwischen Primär- und Sekundärachse verteilt.From the DE 103 196 81 A1 is a module for a hybrid four-wheel drive known. In this case, a module is provided with at least three shafts, which is designed as summation. The drive power is distributed between the primary and secondary axes.

Aus der DE 11 2009 004 352 T5 ist ein gattungsbildendes Modul bekannt.From the DE 11 2009 004 352 T5 is a generic module known.

Aus der DE 10 2013 009 081 A1 ist es bekannt, eine elektrische Maschine über eine Kupplungseinrichtung und zwei Schaltstellungen mit einer Abtriebswelle zu verbinden.From the DE 10 2013 009 081 A1 It is known to connect an electric machine via a coupling device and two switch positions with an output shaft.

Beschreibung der ErfindungDescription of the invention

Es ist Aufgabe der Erfindung, ein bestehendes Modul durch ein hybridisiertes System zu ersetzen, um den zusätzlichen Kraftstoffverbrauch durch Allrad durch Rekuperation zu kompensieren. Durch die elektrische Maschine soll die Allradfähigkeit realisiert werden und auch die Möglichkeit der Rekuperation soll gegeben sein.It is an object of the invention to replace an existing module by a hybridized system to compensate for the additional fuel consumption by four-wheel by recuperation. By the electric machine, the four-wheel drive is to be realized and also the possibility of recuperation should be given.

Die Aufgabe wird gelöst durch ein Fahrzeug mit Längsmotor und permanenten Vorderachsantrieb, das einen Verbrennungsmotor und eine elektrische Maschine aufweist, wobei ein Modul Antriebsmomente bedarfsgerecht verteilt,
wobei das Modul mit zwei Wellen verbunden ist, wobei eine Hauptwelle als Eingangswelle, eine Sekundärwelle als Antriebswelle für die Hinterachse dient und eine Zwischenwelle von der elektrischen Maschine im Modul ein Drehmoment aufbringbar ist,
wobei das Modul ein Reduktionsgetriebe und ein Leistungssummiergetriebe aufweist und die summierte Ausgangsleistung des Leistungssummiergetriebes an der Sekundärwelle und/oder der Hauptwelle anliegt, wobei eine Schalteinheit oder ein Schaltelement die summierte Ausgangsleistung des Leistungssummiergetriebes zwischen einem Vorderradantriebsmodus und einem Allradantriebsmodus schaltet.The object is achieved by a vehicle with a longitudinal engine and permanent front-axle drive, which has an internal combustion engine and an electric machine, wherein a module distributes drive torques on demand,
wherein the module is connected to two shafts, wherein a main shaft serves as an input shaft, a secondary shaft as a drive shaft for the rear axle and an intermediate shaft of the electric machine in the module torque is applied,
wherein the module comprises a reduction gear and a power summing gear and the summed output power of the power summation gear is applied to the secondary shaft and / or the main shaft, wherein a switching unit or a switching element switches the summed output power of the Leistungssummiergetriebes between a front-wheel drive mode and a four-wheel drive mode.

Die Lösung kombiniert den Vorteil von Reibkupplungssystemen und Differential-Systemen mit einer vollständig variablen Drehmomentverteilung zwischen Primär- und Sekundärachse, auch bei vorliegenden Drehzahldifferenzen zwischen den Achsen.The solution combines the advantages of friction clutch systems and differential systems with a fully variable torque distribution between the primary and secondary axles, even with the speed differences between the axles.

Die Verwendung eines Zweiganggetriebes als Hybridgetriebe löst das Dilemma des elektrischen Antriebs, so dass ein hoch übersetzter Gang den Anforderungen nach elektrischem Fahren gerecht wird. Der niedrig übersetzte Gang kann für ein ideales Energiewiedergewinnungsverfahren ausgelegt werden.The use of a two-speed gearbox as a hybrid transmission solves the dilemma of the electrical Drive, so that a highly geared gear meets the requirements for electric driving. The low gear ratio can be designed for an ideal energy recovery process.

Dabei wird der Großteil der Antriebsleistung, z.B.: 90% von der Verbrennungskraftmaschine über die Kardanwelle und ein kleiner Teil, z.B.: 10% von der elektrischen Maschine mit z.B.: 48V geliefert. Zusätzliche steuert die elektrische Maschine durch das gestellte Drehmoment, das gesamte Drehmoment, das an der Sekundärachse abgegeben wird. Bei auftretenden Drehzahldifferenzen zwischen Vorderachse und Hinterachse kann das Drehmoment zwischen Vorder- und Hinterachse dennoch vollvariabel verteilt werden.The majority of the drive power, for example: 90% of the internal combustion engine via the cardan shaft and a small part, for example: 10% of the electric machine with 48V, for example. In addition, the electric machine controls by the set torque, the total torque that is delivered to the secondary axis. When occurring speed differences between the front and rear axle, the torque between the front and rear axles can still be distributed fully variable.

Es ist von Vorteil, dass die Schalteinheit an der Sekundärwelle angreift.It is advantageous that the switching unit acts on the secondary shaft.

Eine weitere vorteilhafte Lösung wird erzielt, indem das Schaltelement durch Abbremsen eines Planetenträgers des Leistungssummiergetriebes schaltet.A further advantageous solution is achieved by switching the switching element by braking a planetary carrier of the Leistungssummiergetriebes.

Die Zweigängigkeit wird genutzt, um hohes Drehmoment im reinen elektrischen Modus zu erhalten, wobei der Planetenträger des Planetengetriebes eingebremst und ein Neutralgang eingelegt wird.The Zweängigkeit is used to obtain high torque in all-electric mode, the planet carrier of the planetary gear is braked and a neutral gear is engaged.

Die Ausgestaltung des Schaltelements ist form-, reib- oder kraftschlüssig.The design of the switching element is positive, frictional or non-positive.

In der Ausführungsform ist es von Vorteil, dass mindestens ein Schaltaktuator das Schaltelement und oder die Schalteinheit ansteuert.In the embodiment, it is advantageous for at least one shift actuator to actuate the shift element and / or the shift unit.

Dadurch kann man je nach Regel- und Schaltstrategie die Ansteuerung über einen gemeinsamen Schaltaktuator oder getrennte Schaltaktuatoren ausgestalten.As a result, depending on the control and switching strategy, the control can be configured via a common shift actuator or separate shift actuators.

Die optionale Synchronisierung der Schalteinheit erlaubt die Abkoppelung des Sekundärantriebsstrangs.The optional synchronization of the switching unit allows the decoupling of the secondary power train.

Weiterhin ist es möglich, dass der sekundäre Antriebsstrang, die Hinterachse, eine Verbindung zur Stilllegung der Hinterachse aufweist.Furthermore, it is possible that the secondary drive train, the rear axle, has a connection for decommissioning the rear axle.

Die Abkoppelung des sekundären Antriebsstrangs reduziert die Verluste in einem reinen Zweirad-Betrieb.The decoupling of the secondary powertrain reduces the losses in a pure two-wheeler operation.

In einer vorteilhaften Ausführungsform ist die Verbindung eine formschlüssige Verbindung und mit einer reibschlüssigen Verbindung in der Schalteinheit einsetzbar.In an advantageous embodiment, the connection is a positive connection and can be used with a frictional connection in the switching unit.

In einer weiteren vorteilhaften Ausführungsform ist die Verbindung eine reibschlüssige Verbindung und mit einer formschlüssigen Verbindung in der Schalteinheit einsetzbar.In a further advantageous embodiment, the connection is a frictional connection and can be used with a positive connection in the switching unit.

Vorteilhafterweise weist die Schalteinheit auch eine Neutralstellung auf.Advantageously, the switching unit also has a neutral position.

Durch Anwendung einer Schalteinheit mit drei Schaltstellungen kann die elektrische Maschine auch direkt an die Räder einer Achse des Fahrzeugs gekoppelt werden und damit die Mild-Hybridfunktionalität bestehend aus Zusatzleistung, Energierückgewinnung, elektrischen Fahren dargestellt werden.By using a switching unit with three switching positions, the electric machine can also be coupled directly to the wheels of an axle of the vehicle and thus the mild hybrid functionality consisting of additional power, energy recovery, electric driving can be represented.

Über das Hauptgetriebe 7 wird zudem eine Hauptwelle 3 angetrieben. Die Sekundärwelle 4 ist antriebswirksam mit der Hinterachse 8 verbunden.In 2 such a permanent front-wheel drive vehicle is shown schematically. An internal combustion engine 6 is installed longitudinally in the vehicle and directly with a main gearbox 7 connected. To the main gearbox 7 is a module in this example 1 connected. The main gearbox 7 is driving effective with the front axle 9 connected, which is shown schematically on the oblique connection in the drawing. About the main gearbox 7 also becomes a main wave 3 driven. The secondary shaft 4 is driving effective with the rear axle 8th connected.

Die Hinterachse weist in diesem Ausführungsbeispiel eine schaltbare und unterbrechbare Verbindung 70 auf, mit der der Antrieb auf der Hinterachse entkoppelt werden kann.The rear axle has in this embodiment, a switchable and interruptible connection 70 on, with the drive on the rear axle can be decoupled.

In 1 ist ein erfindungsgemäßes Modul 1 dargestellt. Das erfindungsgemäße Modul 1 besteht im Wesentlichen aus einem Leistungssummierungsgetriebe 11, einem Reduktionsgetriebe 12 und einer elektrischen Maschine 2. Die elektrische Maschine 2 sitzt auf einer Zwischenwelle 5. Das Modul 1 stellt ein Überlagerungsgetriebe dar, das eine gewisse Verteilungsfunktion an Drehmoment erfüllt.In 1 is a module according to the invention 1 shown. The module according to the invention 1 consists essentially of a power summing gear 11 a reduction gearbox 12 and an electric machine 2 , The electric machine 2 sits on an intermediate shaft 5 , The module 1 recruits Superposition gear, which fulfills a certain distribution function of torque.

Das Modul ist in der 2 direkt am Hauptgetriebe angeordnet, für seien Funktion kann es aber auch entlang der Sekundärachse 4 oder an der Hinterachse 8 angebracht sein.The module is in the 2 arranged directly on the main gear, for its function but it can also along the secondary axis 4 or at the rear axle 8th to be appropriate.

Die elektrische Maschine 2 treibt das Reduktionsgetriebe 12, genauer in die erste Stufe 26a eines Stirnradsatzes 26 ein, der dann die zweite Stufe 26 b des Stirnradsatzes antreibt.The electric machine 2 drives the reduction gear 12 , more precisely in the first stage 26a a spur gear set 26 one, then the second stage 26 b of the spur gear sets.

Die elektrische Maschine 2 ist direkt oder indirekt im Ausführungsbeispiel über die zweite Stufe 26 b des Stirnradsatzes mit einem Sonnenrad 21 des Leistungssummiergetriebes 11 verbunden, dass das Stützmoment zur Verfügung stellt, welches das Drehmoment der Sekundärachse 4 definiert. Das Leistungssummiergetriebe ist als Planetenantrieb aufgebaut.The electric machine 2 is directly or indirectly in the embodiment via the second stage 26 b of the spur gear set with a sun gear 21 of the power summation gearbox 11 connected, that provides the supporting torque, which determines the torque of the secondary axis 4 Are defined. The Leistungssummiergetriebe is constructed as a planetary drive.

Das Hohlrad 24 des Leistungssummierungsgetriebes 11 ist antriebswirksam mit der Hauptwelle 3 verbunden. Das summierte Drehmoment von Sonne 21 und Hohlrad 24 wird an die Sekundärwelle 4 über einen Planetenträger 23 übertragen.The ring gear 24 of the power summing gear 11 is drive-effective with the main shaft 3 connected. The summed torque of sun 21 and ring gear 24 gets to the secondary shaft 4 over a planet carrier 23 transfer.

Durch das Leistungssummierungsgetriebe 11 wird ein Teil der Gesamtleistung des Verbrennungsmotors 6, welches über das Hauptgetriebe 7 dem Modul 1 zugeführt wird, durch Stützen der elektrischen Maschine 2 abgezweigt und mit der Leistung der elektrischen Maschine 2 verstärkt. Dies ermöglicht eine vollvariable Drehmomentverteilung zwischen Vorderachse 9 und Hinterachse 8 mit einer hohen Genauigkeit.Through the power summation gearbox 11 becomes part of the total power of the internal combustion engine 6 which is via the main gearbox 7 the module 1 is supplied by supporting the electric machine 2 branched off and with the power of the electric machine 2 strengthened. This allows a fully variable torque distribution between the front axle 9 and rear axle 8th with a high accuracy.

Das Drehmoment der elektrischen Maschine 2 wird durch das Reduktionsgetriebe 12 so übersetzt, dass ein benötigtes Stützmoment am Sonnenrad 21 des Leistungssummierungsgetriebes 11 anliegt, um ein gewünschtes Drehmoment an die Hinterachse 9 abzuzweigen, z.B.: 1300 Nm. Im Leistungssummierungsgetriebe 11 steuert die elektrische Maschine 2 einen Teil, z.B. 10% = 130 Nm, nach dem Reduktionsgetriebe 12 bei und der Rest, z.B.: 90% = 1170 Nm wird von der Hauptwelle 3 abgezweigt.The torque of the electric machine 2 is through the reduction gear 12 translated so that a required supporting moment on the sun gear 21 of the power summing gear 11 is applied to a desired torque to the rear axle 9 to divert, for example: 1300 Nm. In the power summing gearbox 11 controls the electric machine 2 one part, eg 10% = 130 Nm, after the reduction gear 12 at and the rest, eg: 90% = 1170 Nm is from the main shaft 3 diverted.

Durch den Zusammenhang der Drehmomentverteilung, z.B.: 10%:90% definiert sich die Übersetzung des Leistungssummierungsgetriebes 11. Durch die Abhängigkeit des Drehmoments der Vorderachse 9 vom Drehmoment der elektrischen Maschine 2 besteht die Möglichkeit einen reinen Zweirad-Betrieb zu realisieren, wenn das Drehmoment der elektrischen Maschine 2 gleich 0 Nm beträgt.Due to the relationship between the torque distribution, eg: 10%: 90%, the ratio of the power summation gear is defined 11 , Due to the dependence of the torque of the front axle 9 from the torque of the electric machine 2 it is possible to realize a pure two-wheel operation, if the torque of the electric machine 2 equal to 0 Nm.
