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. It is known, for example, to support an internal combustion engine with the aid of 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 Doppelkupplungsgetriebe, das dazu vorgesehen ist, mit einer ersten Antriebsmaschine, insbesondere einem Verbrennungsmotor, gekoppelt zu werden, und einem lastschaltfähigen Automatikgetriebe, das dazu vorgesehen ist, mit einer zweiten Antriebsmaschine, insbesondere einem Elektromotor, gekoppelt zu werden, wobei das lastschaltfähige Automatikgetriebe zum Zusammenführen der Antriebsleistungen der Antriebsmaschinen mit einer Welle des Doppelkupplungsgetriebes, insbesondere einer Abtriebswelle, koppelbar ist.The above object is achieved by a transmission arrangement for a hybrid drive, with a dual-clutch transmission, which is intended to be coupled to a first drive machine, in particular an internal combustion engine, and a powershiftable automatic transmission, which is provided with a second drive machine, in particular an electric motor to be coupled, wherein the powershiftable automatic transmission for merging the drive power of the engine with a shaft of the dual clutch transmission, in particular an output shaft, can be coupled.
Wenn hier von dem Koppeln der Getriebe und/oder der Getriebewellen 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.When it is referred to here of the coupling of the transmission and / or the transmission shafts of the transmission, this means the production of a path for power transmission within the transmission arrangement between at least two transmission shafts via one or more gear stages.
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. Die Gangwechsel in den Getrieben erfolgen dabei bevorzugt ohne Zugkraftunterbrechung. Mit anderen Worten kann eine am Getriebeeingang eines jeweiligen Getriebes eingebrachte Leistung einer Antriebsmaschine auch während des Schaltvorgangs mithilfe lastschaltfähiger Kupplungen dauerhaft zum Getriebeausgang übertragen werden.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 changes in the transmissions are preferably carried out without interruption of traction. In other words, a power input of a drive machine introduced at the transmission input of a respective transmission can also be permanently transmitted to the transmission output during the shifting process by means of load-shift-capable clutches.
Das lastschaltfähige Automatikgetriebe ist zum Zusammenführen der Antriebsleistungen der Antriebsmaschinen mit einer Welle des ersten Doppelkupplungsgetriebes koppelbar.The powershiftable automatic transmission can be coupled to merge the drive powers of the drive machines with a shaft of the first dual-clutch transmission.
Bevorzugt kann die Kopplung über eine zwischen der Welle des Doppelkupplungsgetriebes und einer Welle des lastschaltfähigen Automatikgetriebes vorgesehene Zahnradstufe erfolgen, die unabhängig und separat von den Gängen bzw. Gangradpaaren des Doppelkupplungsgetriebes ist.Preferably, the coupling can take place via a provided between the shaft of the dual clutch transmission and a shaft of the powershiftable automatic transmission gear stage, which is independent and separate from the gears or Gangradpaaren the dual clutch transmission.
Die Gänge des Doppelkupplungsgetriebes sind bevorzugt frei mit den Gängen des lastschaltfähigen Automatikgetriebes kombinierbar, so dass das von den Antriebsmaschinen bereitgestellte Drehmoment insgesamt feiner einstellbar ist.The gears of the dual-clutch transmission are preferably freely combined with the gears of the powershiftable automatic transmission, so that the torque provided by the drive motors is altogether finer adjustable.
Insbesondere kann das lastschaltfähige Automatikgetriebe mit einer Abtriebswelle des Doppelkupplungsgetriebes koppelbar sein. Dabei kann eine in voranstehend beschriebener Weise separate Zahnradstufe eingesetzt werden. Die Getriebeanordnung kann derart gestaltet sein, dass die Gangradpaare des Doppelkupplungsgetriebes unabhängig von den Gangradpaaren des lastschaltfähigen Automatikgetriebes mit einer Abtriebswelle des Doppelkupplungsgetriebes koppelbar sind und umgekehrt.In particular, the power shiftable automatic transmission can be coupled to an output shaft of the dual-clutch transmission. In this case, a separate gear stage can be used in the manner described above. The gear arrangement may be designed such that the Gangradpaare the dual clutch transmission are independent of the Gangradpaaren the powershiftable automatic transmission with an output shaft of the dual clutch transmission can be coupled and vice versa.
Die abtriebsseitige Anbindung des lastschaltfähigen Automatikgetriebes an das Doppelkupplungsgetriebe hat den Vorteil, dass die Antriebsleistungen der jeweiligen Antriebsmaschinen innerhalb der Getriebeanordnung erst spät zusammengeführt werden. Folglich werden möglichst wenige Komponenten der Getriebeanordnung mit dem Summendrehmoment, dass sich aus der Summe der Drehmomente der ersten und der zweiten Antriebsmaschine ergibt, beaufschlagt. Die Getriebeanordnung kann dadurch kompakter und leichter gebaut werden.The output-side connection of the powershiftable automatic transmission to the dual-clutch transmission has the advantage that the drive power of the respective drive machines are brought together late within the transmission assembly. Consequently, as few components of the gear arrangement with the total torque that results from the sum of the torques of the first and the second drive machine, applied. The gear assembly can be made more compact and lighter.
Bevorzugt kann es sich bei der Getriebeanordnung um ein Getriebe für den Quereinbau handeln. Die Getriebeanordnung eignet sich dabei sowohl für den Quereinbau im Heck als auch im Frontbereich eines Fahrzeugs.The transmission arrangement may preferably be a transmission for transverse installation. The gear arrangement is suitable both for transverse installation in the rear and in the front of a vehicle.
Nach einer Weiterbildung der Getriebeanordnung ist das Doppelkupplungsgetriebe ein 3-Wellen-Doppelkupplungsgetriebe. Dabei kann auf bereits bekannte, zuverlässige Doppelkupplungsgetriebe zurückgegriffen werden.According to a development of the gear arrangement, the dual-clutch transmission is a 3-shaft dual clutch transmission. It can be used on already known, reliable dual-clutch transmission.
Ein solches 3-Wellen-Doppelkupplungsgetriebe kann eine Antriebswelle, die zwei Teilgetriebewellen hat, zwei Abtriebswellen und eine Doppelkupplung aufweisen. Dadurch wird eine axial kompakte Bauform des Doppelkupplungsgetriebes erreicht.Such a 3-shaft dual clutch transmission may have a drive shaft which has two partial transmission shafts, two output shafts and a double clutch. As a result, an axially compact design of the dual-clutch transmission is achieved.
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.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 to load a the Electric motor associated battery can be used.
Dabei kann eine der Abtriebswellen des Doppelkupplungsgetriebes ein Losrad aufweisen, über das das lastschaltfähige Automatikgetriebe im Generatorbetrieb mit dem Doppelkupplungsgetriebe koppelbar ist.In this case, one of the output shafts of the dual clutch transmission having a loose wheel, via which the power shiftable automatic transmission can be coupled in generator mode with the dual clutch transmission.
Die erste Antriebsmaschine kann im Stand oder Fahrbetrieb eines anzutreibenden Fahrzeugs mit dem Elektromotor gekoppelt werden. Die jeweilige dem Losrad zugeordnete Abtriebswelle des ersten Getriebes wird dabei mithilfe des Losrads ”überbrückt”.The first drive machine can be coupled to the electric motor during standstill or driving operation of a vehicle to be driven. The respective output shaft of the first transmission assigned to the idler gear is thereby "bridged" by means of the idler gear.
Dem Losrad kann ein Schaltelement zugeordnet sein, das zum Festlegen des Losrads an der Abtriebswelle dient, so dass das Losrad gleichermaßen als Anbindung des lastschaltfähigen Automatikgetriebes an die Abtriebswelle des Doppelkupplungsgetriebes dienen kann.The idler gear can be assigned a switching element which serves to set the idler gear on the output shaft, so that the idler gear can equally serve as a connection of the powershiftable automatic transmission to the output shaft of the dual clutch transmission.
Auf der Antriebswelle des Doppelkupplungsgetriebes kann bevorzugt ein ebenfalls als Losrad ausgeführtes Ladezahnrad angeordnet sein, dem seinerseits ein Schaltelement zugeordnet ist und das mit dem Losrad der Abtriebswelle kämmt. Je nach gefordertem Betriebsmodus, d. h. Generator- oder Motorbetrieb, ist entweder das Schaltelement des Ladezahnrads oder das Schaltelement des Losrads der Abtriebswelle eingerückt, um das jeweilige Losrad mit der zugeordneten Welle drehfest zu verbinden.On the drive shaft of the dual-clutch transmission can also be arranged a likewise designed as a loose gear Ladezahnrad, which in turn is associated with a switching element and which meshes with the idler gear of the output shaft. Depending on the required operating mode, d. H. Generator or motor operation, either the switching element of the loading gear or the switching element of the idler gear of the output shaft is engaged to connect the respective idler gear rotatably with the associated shaft.
Um in einfacher Weise eine lastschaltfähige Anordnung bereitzustellen, weist das lastschaltfähige Automatikgetriebe wenigstens zwei Wellen auf, wobei eine der Wellen zwei Teilgetriebewellen hat, die über lastschaltfähige Kupplungen in die Leistungsübertragung eingebunden werden können. Dabei ist wenigstens ein erster Gang des lastschaltfähigen Automatikgetriebes der ersten Teilgetriebewelle zugeordnet, während ein zweiter Gang der zweiten Teilgetriebewelle zugeordnet ist.In order to provide a load-shiftable arrangement in a simple manner, the powershiftable automatic transmission has at least two shafts, wherein one of the shafts has two partial transmission shafts, which can be integrated into the power transmission via load-shiftable clutches. In this case, at least one first gear of the powershiftable automatic transmission of the first partial transmission shaft is assigned, while a second gear is associated with the second partial transmission shaft.
Entsprechend einer Weiterbildung der Getriebeanordnung weist das Doppelkupplungsgetriebe wenigstens sechs Gänge auf, wobei das lastschaltfähige Automatikgetriebe alternativ oder ergänzend wenigstens zwei Gänge hat. Die Gänge des Doppelkupplungsgetriebes und des lastschaltfähigen Automatikgetriebes sind insbesondere frei miteinander kombinierbar bzw. unabhängig voneinander schaltbar.According to a development of the gear arrangement, the dual clutch transmission has at least six gears, wherein the power shiftable automatic transmission alternatively or additionally has at least two gears. The gears of the dual clutch transmission and the powershiftable automatic transmission are in particular freely combined with each other or independently switchable.
Es kann vorgesehen sein, dass der erste, dritte und fünfte Gang der einen Teilgetriebewelle des Doppelkupplungsgetriebes und der zweite, vierte und sechste Gang der jeweils anderen Teilgetriebewelle des Doppelkupplungsgetriebes zugeordnet sind.It can be provided that the first, third and fifth gear are assigned to a partial transmission shaft of the dual-clutch transmission and the second, fourth and sixth gear of the respective other partial transmission shaft of the dual-clutch transmission.
Gemäß weiteren Ausgestaltungen der Erfindung ist es möglich, für das Doppelkupplungsgetriebe mehr als sechs Gänge, beispielsweise bis zu zwölf Gänge oder mehr vorzusehen. Alternativ kann das Doppelkupplungsgetriebe weniger als sechs, beispielsweise fünf, vier oder weniger Gänge aufweisen.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 dual-clutch transmission. Alternatively, the dual-clutch transmission may have fewer than six, for example, five, four or fewer gears.
Alternativ oder ergänzend kann das lastschaltfähige Automatikgetriebe mehr als zwei Gänge, insbesondere bis zu zwölf Gänge oder mehr aufweisen.Alternatively or additionally, the power shift automatic transmission can have more than two gears, in particular up to twelve gears or more.
In der voranstehend beschriebenen Ausgestaltung des Doppelkupplungsgetriebes ist es möglich, die unmittelbar aufeinanderfolgenden Gänge des Doppelkupplungsgetriebes ohne Zugkraftunterbrechung zu schalten.In the above-described embodiment of the dual-clutch transmission, it is possible to switch the immediately successive gears of the dual-clutch transmission without interruption of traction.
Eine unabhängig von den Gängen des Doppelkupplungsgetriebes erfolgende Anbindung des lastschaltfähigen Automatikgetriebes kann zudem einen Gangwechsel zwischen den geraden oder ungeraden Gängen des Doppelkupplungsgetriebes ohne Zugkraftunterbrechung gewährleisten.An independent of the gears of the dual clutch transmission connecting the powershiftable automatic transmission can also ensure a gear change between the even or odd gears of the dual clutch transmission without interruption of traction.
Beispielsweise kann während eines Gangwechsels bzw. Schaltvorgangs im Doppelkupplungsgetriebe, wobei unmittelbar von dem 1. Gang in den 3. Gang geschaltet wird, die Zugkraftunterbrechung, die dabei durch die Entkopplung der entsprechenden Teilgetriebewelle des Doppelkupplungsgetriebes von der Abtriebswelle auftritt, durch ein Zuschalten oder Erhöhen des Drehmoments der zweiten Antriebsmaschine ausgeglichen werden.For example, during a gear change or shift in the dual-clutch transmission, being switched directly from the 1st gear in the 3rd gear, the traction interruption, which occurs due to the decoupling of the corresponding partial transmission shaft of the dual clutch transmission from the output shaft, by connecting or increasing the Torque of the second drive machine can be compensated.
