Description
Die Erfindung betrifft eine Getriebeanordnung für einen Hybridantrieb.The invention relates to a transmission arrangement for a hybrid drive.
In modernen Kraftfahrzeugen werden verschiedene Antriebskonzepte in sogenannten Hybridantrieben miteinander kombiniert. So ist es bekannt, beispielsweise einen Verbrennungsmotor mithilfe eines Elektromotors zu unterstützen und umgekehrt.In modern motor vehicles, various drive concepts are combined in so-called hybrid drives. So it is known, for example, to support an internal combustion engine using an electric motor and vice versa.
Mithilfe von Getriebeanordnungen wird die Leistung der Antriebsmaschinen an die anzutreibenden Räder des Fahrzeugs weitergeleitet. Dabei besteht die Forderung, die jeweiligen Motoren möglichst effizient zu betreiben.With the aid of gear arrangements, the power of the drive machines is transmitted to the driven wheels of the vehicle. There is a requirement to operate the respective engines as efficiently as possible.
Aufgabe der vorliegenden Erfindung ist es, eine verbesserte Getriebeanordnung für einen Hybridantrieb anzugeben.Object of the present invention is to provide an improved transmission arrangement for a hybrid drive.
Die voranstehend genannte Aufgabe wird gelöst durch eine Getriebeanordnung für einen Hybridantrieb, mit einem ersten Getriebe, das als Doppelkupplungsgetriebe ausgeführt und dazu vorgesehen ist, mit einer ersten Antriebsmaschine, insbesondere einem Verbrennungsmotor, gekoppelt zu werden, und einem zweiten Getriebe, das dazu vorgesehen ist, mit einer zweiten Antriebsmaschine, insbesondere einem Elektromotor, gekoppelt zu werden, wobei das erste und das zweite Getriebe zum Zusammenführen der Antriebsleistungen der Antriebsmaschinen mit einem Differential koppelbar sind.The above object is achieved by a transmission arrangement for a hybrid drive, with a first transmission, which is designed as a dual-clutch transmission and is intended to be coupled to a first drive machine, in particular an internal combustion engine, and a second transmission, which is provided to be coupled with a second drive machine, in particular an electric motor, wherein the first and the second gear for coupling the drive powers of the drive machines are coupled with a differential.
Wenn hier von dem Koppeln der Getriebe und/oder der Wellen der Getriebe die Rede ist, so ist damit die Herstellung eines Pfads zur Leistungsübertragung innerhalb der Getriebeanordnung zwischen wenigstens zwei Getriebewellen über eine oder mehrere Zahnradstufen gemeint.Whenever the coupling of the gearboxes and / or the shafts of the gearboxes is mentioned here, this refers to the production of a path for power transmission within the gearbox arrangement between at least two gearbox shafts via one or more gearwheel stages.
Sowohl das erste als auch das zweite Getriebe können die von den jeweiligen Antriebsmaschinen bereitgestellte Leistung jeweils unmittelbar auf ein Differential, übertragen. D. h. die Drehmomente werden in diesem Fall erst im Bereich des Getriebeausgangs des jeweiligen Getriebes am Differential addiert.Both the first and second transmissions may transmit the power provided by the respective prime mover directly to a differential, respectively. Ie. the torques are added in this case only in the range of the transmission output of the respective gear on the differential.
Das abtriebsseitige Zusammenführen der Drehmomente bzw. der Antriebsleistungen hat den Vorteil, dass möglichst wenige Komponenten, insbesondere lediglich das Differential, mit dem Summendrehmoment, das sich aus der Summe der Drehmomente der ersten und der zweiten Antriebsmaschine ergibt, beaufschlagt werden. Die Getriebeanordnung kann dadurch kompakter und leichter gebaut werden.The output-side merging of the torques and the drive powers has the advantage that as few components, in particular only the differential, with the total torque, resulting from the sum of the torques of the first and the second drive machine, are applied. The gear assembly can be made more compact and lighter.
Zudem sind die Gänge des ersten Getriebes frei mit den Gängen des zweiten Getriebes kombinierbar, so dass das von den Antriebsmaschinen bereitgestellte Drehmoment insgesamt feiner einstellbar ist. Die Gänge bzw. Gangradpaare des ersten Getriebes und die Gänge bzw. Gangradpaare des zweiten Getriebes sind separat voneinander schaltbar und unabhängig voneinander mit dem Abtrieb bzw. dem Differential koppelbar.In addition, the gears of the first transmission can be freely combined with the gears of the second transmission, so that the torque provided by the drive motors is altogether finer adjustable. The gears or gear pairs of the first gear and the gears or gear pairs of the second transmission are separately switchable and independently coupled to the output or the differential.
Nach einer Weiterbildung der Getriebeanordnung ist das zweite Getriebe ein lastschaltfähiges Automatikgetriebe.According to a development of the gear arrangement, the second transmission is a powershiftable automatic transmission.
Durch die Kombination eines Doppelkupplungsgetriebes mit einem lastschaltfähigen Automatikgetriebe in einer Getriebeanordnung wird erreicht, dass sowohl die Gänge, die der ersten Antriebsmaschine zugeordnet sind, als auch die Gänge, die der zweiten Antriebsmaschine zugeordnet sind, lastschaltfähig sind. Der Gangwechsel in dem ersten und dem zweiten Getriebe erfolgen dabei bevorzugt ohne Zugkraftunterbrechung.The combination of a dual-clutch transmission with a power shiftable automatic transmission in a transmission arrangement ensures that both the gears associated with the first drive engine and the gears associated with the second drive engine are load-shiftable. The gear change in the first and the second transmission are preferably carried out without interruption of traction.
Mit anderen Worten kann eine am Getriebeeingang eines jeweiligen Getriebes eingebrachte Leistung einer Antriebsmaschine auch während des Schaltvorgangs mithilfe lastschaltfähiger Kupplungen dauerhaft zum Getriebeausgang des jeweiligen Getriebes übertragen werden.In other words, a power of a drive machine introduced at the transmission input of a respective transmission can also be transmitted permanently to the transmission output of the respective transmission during the shifting process by means of load-shift-capable clutches.
Bevorzugt kann es sich bei der Getriebeanordnung um ein Automatikgetriebe handeln, insbesondere für den Quer-Einbau. Die Getriebeanordnung ist sowohl für den Einbau im Heck als auch im Frontbereich eines Fahrzeugs geeignet.The transmission arrangement may preferably be an automatic transmission, in particular for transverse installation. The gear arrangement is suitable both for installation in the rear and in the front of a vehicle.
Nach einer Weiterbildung der Getriebeanordnung sind wenigstens ein Gang, insbesondere wenigstens zwei Gänge, des ersten Getriebes als Windungsgänge ausgeführt. Auf diese Weise kann das Doppelkupplungsgetriebe kompakter gebaut werden, da mit beispielsweise vier Zahnradpaarungen in dem ersten Getriebe sechs Gänge realisiert werden können.According to a development of the gear arrangement, at least one gear, in particular at least two gears, of the first gear are designed as winding turns. In this way, the dual-clutch transmission can be made more compact, since six gears can be realized with, for example, four gear pairs in the first transmission.
Das erste Getriebe kann eine Antriebswelle, die zwei Teilgetriebewellen hat, und eine Abtriebswelle aufweisen.The first transmission may include a drive shaft having two partial transmission shafts and an output shaft.
Um einen Windungsgang abzubilden, kann wenigstens ein Schaltelement vorgesehen sein, das dazu ausgebildet ist, wenigstens zwei benachbart auf der Abtriebswelle angeordnete Losräder zweier Gangradpaarungen relativ zueinander drehfest zu koppeln, wobei die beiden Losräder relativ zu der Abtriebswelle im miteinander gekoppelten Zustand weiterhin frei beweglich bzw. drehbar sind. Die entsprechend zugehörigen Festräder der Gangradpaarungen sind auf verschiedenen Teilgetriebewellen angeordnet.In order to map a Windungsgang, at least one switching element may be provided which is adapted to rotatably at least two adjacent arranged on the output shaft idler gears of two Gangradpaarungen relative to each other, wherein the two idler gears relative to the output shaft in the mutually coupled state continues to move freely or are rotatable. The correspondingly associated fixed wheels of the Gangradpaarungen are arranged on different partial transmission shafts.
Ein beispielsweise in eine erste Teilgetriebewelle eingeleitetes Drehmoment wird von einem ersten Festrad, das dieser Teilgetriebewelle zugeordnet ist, zunächst auf die beiden gekoppelten Losräder übertragen. Über die gekoppelten und frei zur Abtriebswelle drehbaren Losräder wird die Antriebsleistung zurück auf ein zweites Festrad übertragen, das einer zweiten Teilgetriebewelle zugeordnet ist. Die zweite Teilgetriebewelle wird daher mittels der ersten Teilgetriebewelle angetrieben, wobei über die im Kraftfluss angeordneten Gangradpaarungen eine Übersetzung bzw. Untersetzung der Antriebsdrehzahl und des Antriebsmoments erfolgt. A torque introduced, for example, into a first partial transmission shaft is first transmitted by a first fixed wheel, which is assigned to this partial transmission shaft, to the two coupled idler gears. About the coupled and freely rotatable to the output shaft loose wheels, the drive power is transmitted back to a second fixed wheel, which is assigned to a second partial transmission shaft. The second partial transmission shaft is therefore driven by means of the first partial transmission shaft, whereby a translation or reduction of the input rotational speed and the drive torque takes place via the gear wheel pairings arranged in the force flow.
Schließlich wird die Leistung von der zweiten Teilgetriebewelle über eine dritte Gangradpaarung in konventioneller Weise auf die Abtriebswelle übertragen. Jede der drei beteiligten Gang radpaarungen für sich genommen bildet ebenfalls einen Gang des Doppelkupplungsgetriebes, so dass insgesamt mit drei Zahnradpaarungen vier Gänge realisiert werden können.Finally, the power is transmitted from the second partial transmission shaft via a third gear pairing in a conventional manner to the output shaft. Each of the three gear pairings taken by itself also forms a gear of the dual-clutch transmission, so that a total of three gear pairings four gears can be realized.
Bevorzugt weist das erste Getriebe wenigstens zwei Windungsgänge auf.The first transmission preferably has at least two winding turns.
Die zweite Antriebsmaschine kann ein Elektromotor sein, der mit der ersten Antriebsmaschine koppelbar und als Generator betreibbar ist. Die erste Antriebsmaschine kann daher zum Laden einer dem Elektromotor zugeordneten Batterie verwendet werden. Alternativ oder ergänzend ist es möglich, aus dem Differential Leistung in den als Generator arbeitenden Elektromotor zu leiten, insbesondere zum Zwecke der Rekuperation.The second drive machine may be an electric motor which can be coupled to the first drive machine and operated as a generator. The first drive machine can therefore be used to charge a battery associated with the electric motor. Alternatively or additionally, it is possible to conduct power from the differential into the electric motor operating as a generator, in particular for the purpose of recuperation.
Grundsätzlich kann vorgesehen sein, einen Generatorbetrieb eines mit einer hier in Rede stehenden Getriebeanordnung ausgestatteten Hybridfahrzeugs im Fahrbetrieb und/oder im Stand des Fahrzeugs zu ermöglichen.In principle, provision may be made for enabling a generator operation of a hybrid vehicle equipped with a gear arrangement in question here while driving and / or standing in the vehicle.
Insbesondere kann die Getriebeanordnung zusätzliche Kopplungsmittel aufweisen, um einen Generatorbetrieb im Stand eines mit der Getriebeanordnung ausgestatteten Fahrzeugs zu ermöglichen.In particular, the transmission assembly may include additional coupling means to enable generator operation in the state of a vehicle equipped with the transmission assembly.
Die Kopplungsmittel zur Übertragung der Leistung des Verbrennungsmotors über das erste Getriebe auf das zweite Getriebe können beispielsweise eine zusätzliche Stirnradstufe, einen Kettentrieb oder ähnliche Vorrichtungen zur Leistungsübertragung aufweisen.The coupling means for transmitting the power of the internal combustion engine via the first transmission to the second transmission, for example, have an additional spur gear, a chain drive or similar devices for power transmission.
Beispielsweise kann die Abtriebswelle des ersten Getriebes ein Losrad haben, über das das zweite Getriebe im Generatorbetrieb mit dem ersten Getriebe koppelbar ist.For example, the output shaft of the first transmission may have a loose wheel, via which the second transmission can be coupled in generator operation with the first transmission.
Das für den Generatorbetrieb vorgesehene Losrad kann grundsätzlich ein separates, von den Gangradpaaren des ersten Getriebes unabhängiges Zahnrad sein. Nach einer Ausgestaltung der Erfindung ist das für den Generatorbetrieb vorgesehene Losrad jedoch ein Gangrad eines Gangs des ersten Getriebes, dem ein Schaltelement zugeordnet ist, um das Gangrad drehfest mit der Abtriebswelle des ersten Getriebes zu verbinden.The idler gear provided for the generator operation can in principle be a separate gear, independent of the gear wheel pairs of the first gear. According to one embodiment of the invention, however, provided for the generator mode idler gear is a gear wheel of a gear of the first transmission, which is associated with a switching element to rotatably connect the gear wheel with the output shaft of the first transmission.
Im Fall der drehfesten Verbindung des Losrads mit der Abtriebswelle kann eine in das erste Getriebe eingeleitete Antriebsleistung auf die Abtriebswelle des ersten Getriebes übertragen werden. Dabei kann ein Teil der Antriebsleistung über das relativ zur Abtriebswelle fixierte Losrad zur im Generatorbetrieb arbeitenden Elektromaschine übertragen werden.In the case of the rotationally fixed connection of the idler gear to the output shaft, a drive power introduced into the first transmission can be transmitted to the output shaft of the first transmission. In this case, part of the drive power can be transmitted via the idler gear fixed relative to the output shaft to the electric machine operating in generator operation.
Das Losrad kann im von der Abtriebswelle entkoppelten Zustand einerseits zum Standladen und andererseits zum Laden einer Batterie im Fahrbetrieb dienen. Die Abtriebswelle wird dabei von dem Losrad jeweils „überbrückt”, so dass über das Losrad kein Drehmoment auf die Abtriebswelle übertragen wird. Vielmehr dient das Losrad in diesem Fall ausschließlich der Übertagung der Antriebsleistung hin zum zweiten Getriebe. Gleichzeitig kann über eine von dem Losrad separate Gangradpaarung eine Antriebsleistung in die Abtriebswelle eingeleitet werden.The idler gear can be used in the decoupled from the output shaft state on the one hand to stand shop and on the other hand to charge a battery while driving. The output shaft is "bridged" by the idler gear, so that no torque is transmitted to the output shaft via the idler gear. Rather, in this case, the idler gear is used exclusively to transfer the drive power to the second transmission. At the same time a drive power can be introduced into the output shaft via one of the idler gear separate Gangradpaarung.
Entsprechend einer Weiterbildung der Getriebeanordnung weist das erste Getriebe wenigstens sechs Gänge auf, wobei das zweite Getriebe alternativ oder ergänzend wenigstens einen, bevorzugt wenigstens zwei Gänge aufweist. Die Gänge des ersten Getriebes und des zweiten Getriebes sind Insbesondere frei miteinander kombinierbar bzw. unabhängig voneinander schaltbar.According to a development of the transmission arrangement, the first transmission has at least six gears, wherein the second transmission alternatively or additionally has at least one, preferably at least two gears. The gears of the first transmission and the second transmission are in particular freely combined with each other or independently switchable.
Um eine möglichst kompakte Bauform zu erreichen, können zumindest der erste und der sechste Gang des ersten Getriebes als Windungsgänge ausgeführt sind.In order to achieve a compact design as possible, at least the first and the sixth gear of the first transmission can be designed as Windungsgänge.
Gemäß weiteren Ausgestaltungen der Erfindung ist es möglich, für das erste Getriebe mehr als sechs Gänge, beispielsweise bis zu zwölf Gänge oder mehr vorzusehen. Insbesondere können mehr als zwei Windungsgänge vorgesehen sein.According to further embodiments of the invention, it is possible to provide more than six gears, for example up to twelve gears or more, for the first transmission. In particular, more than two winding turns can be provided.
Alternativ kann das erste Getriebe weniger als sechs, beispielsweise fünf, vier oder weniger Gänge aufweisen.Alternatively, the first transmission may have fewer than six, for example five, four or fewer gears.
Alternativ oder ergänzend kann das zweite Getriebe mehr als zwei Gänge, insbesondere bis zu zwölf Gänge oder mehr aufweisen.Alternatively or additionally, the second transmission may have more than two gears, in particular up to twelve gears or more.
Es ist möglich, die unmittelbar aufeinanderfolgenden Gänge des ersten Doppelkupplungsgetriebes ohne Zugkraftunterbrechung zu schalten. It is possible to switch the immediately consecutive gears of the first dual-clutch transmission without interruption of traction.
Eine unabhängig vom ersten Getriebe erfolgende Anbindung des zweiten Getriebes an ein Differenzial kann zudem einen Gangwechsel zwischen den geraden oder ungeraden Gängen des ersten Getriebes ohne Zugkraftunterbrechung ermöglichen. Auf diese Weise kann der Fahrkomfort weiter gesteigert werden.An independent of the first transmission connection of the second transmission to a differential can also allow a gear change between the even or odd gears of the first transmission without interruption of traction. In this way, the ride comfort can be further increased.
Beispielsweise kann während eines Gangwechsels bzw. Schaltvorgangs im ersten Getriebe, wobei unmittelbar vom zweiten Gang in den vierten Gang geschaltet wird, die Zugkraftunterbrechung, die dabei durch die Entkopplung der entsprechenden Teilgetriebewelle des ersten Getriebes von der Abtriebswelle auftritt, durch ein Zuschalten oder Erhöhen des Drehmoments der zweiten Antriebsmaschine ausgeglichen werden.For example, during a gear change or shift operation in the first transmission, which is switched directly from the second gear to the fourth gear, the traction interruption, which occurs due to the decoupling of the corresponding partial transmission shaft of the first transmission from the output shaft, by connecting or increasing the torque be compensated for the second drive machine.

Im Vergleich zu Lösungen, die bereits eine Einbindung des Elektromotors beispielsweise unmittelbar zwischen dem Verbrennungsmotor und dem ersten Getriebe vorsehen, müssen die Getriebe daher wesentlich geringere Lasten ertragen und können kompakter, leichter und kostengünstiger konstruiert werden.Compared to solutions that already provide an integration of the electric motor, for example, directly between the engine and the first transmission, the transmission must therefore endure much lower loads and can be constructed more compact, lighter and more cost-effective.
