Abstract
Die Erfindung betrifft einen Antriebsstrang für ein Kraftfahrzeug, mit mindestens einer Verbrennungskraftmaschine (VKM), mit mindestens einem Getriebe (G), mit mindestens einer Elektromaschine (EM) und mit mindestens einem Freilauf (F,F,F), wobei das Getriebe zwei oder mehr Gänge (1,2,3,4,5,6,R) aufweist. Die Kosteneffizienz des Antriebsstrangs ist dadurch verbessert, dass mindestens ein bestimmter Gang (3,4,5,6) des Getriebes (G) durch einen Freilauf (F,F,F) von der Elektromaschine (EM) abkoppelbar ist.The invention relates to a drive train for a motor vehicle, with at least one internal combustion engine (VKM), with at least one transmission (G), with at least one electric machine (EM) and with at least one freewheel (F, F, F), wherein the transmission two or has more gears (1,2,3,4,5,6, R). The cost-efficiency of the drive train is improved in that at least one specific gear (3,4,5,6) of the transmission (G) by a freewheel (F, F, F) from the electric machine (EM) is decoupled.
Description
Die Erfindung betrifft einen Antriebsstrang für ein Kraftfahrzeug, insbesondere für ein Mild-Hybrid-Fahrzeug, mit den Merkmalen des Oberbegriffes des Patentanspruchs 1.The invention relates to a drive train for a motor vehicle, in particular for a mild hybrid vehicle, having the features of the preamble of
Mild-Hybrid-Fahrzeuge können neben einer Verbrennungskraftmaschine eine Elektromaschine aufweisen, durch welche das Fahrzeug bei geringen Geschwindigkeiten, beispielsweise von ≤ 50 km/h, rein elektrisch angetrieben werden kann. Beim Erreichen eines bestimmten Geschwindigkeitsgrenzwertes wird dann die Verbrennungskraftmaschine gestartet und das Fahrzeug verbrennungsmotorisch angetrieben. Der Antrieb kann dabei rein verbrennungsmotorisch oder auch hybridisch erfolgen. Bei einem hybridischen Antrieb kann die Leistung der Verbrennungskraftmaschine durch die Elektromaschine erhöht werden, was bei bestimmten Fahrzuständen auch als „Boosten“ bezeichnet wird.Mild hybrid vehicles can have, in addition to an internal combustion engine, an electric machine by means of which the vehicle can be driven purely electrically at low speeds, for example of ≦ 50 km / h. Upon reaching a certain speed limit then the internal combustion engine is started and the vehicle driven by internal combustion engine. The drive can be done purely by internal combustion engines or hybrid. In a hybrid drive, the power of the internal combustion engine can be increased by the electric machine, which is also referred to as "boosting" in certain driving conditions.

Die im Stand der Technik bekannten Antriebsstränge für Kraftfahrzeuge sind jedoch noch nicht optimal ausgebildet. So ist ein vor oder nach dem Getriebe angeordneter Freilauf beim Anfahren und/oder niedrigen Geschwindigkeiten und insbesondere in niedrigen Gängen, wie dem ersten und/oder zweiten Gang, hohen mechanischen Belastungen durch Schub-Zug-Wechsel ausgesetzt. Dies erfordert eine stärkere Auslegung des Freilaufs und/oder führt zu einem erhöhten Verschleiß des Freilaufs und somit zu erhöhten Kosten in der Herstellung und/oder Instandhaltung des Antriebsstranges.However, the drive trains known in the art for motor vehicles are not yet optimally designed. Thus, a freewheel arranged before or after the transmission when starting and / or low speeds and in particular in low gears, such as the first and / or second gear, high mechanical loads exposed by push-pull change. This requires a stronger design of the freewheel and / or leads to increased wear of the freewheel and thus to increased costs in the production and / or maintenance of the drive train.
Der Erfindung liegt daher die Aufgabe zu Grunde, den eingangs genannten Antriebsstrang für ein Kraftfahrzeug, derart auszugestalten und weiterzubilden, dass dessen Kosteneffizienz verbessert werden kann.The invention is therefore based on the object, the drive train for a motor vehicle mentioned above, to design and develop such that its cost efficiency can be improved.
Die der Erfindung zugrunde liegende Aufgabe wird durch einen Antriebsstrang für ein Kraftfahrzeug, insbesondere für ein Mild-Hybrid-Fahrzeug, mit den Merkmalen des Patentanspruchs 1 gelöst.The object underlying the invention is achieved by a drive train for a motor vehicle, in particular for a mild hybrid vehicle, having the features of
Dabei weist der Antriebsstrang eine Verbrennungskraftmaschine, ein Getriebe mit zwei oder mehr Gängen, eine Elektromaschine zum Radantrieb und mindestens einen Freilauf auf. Dabei ist, insbesondere lediglich, mindestens ein bestimmter Gang des Getriebes durch einen Freilauf von der Elektromaschine abkoppelbar. Mindestens ein, insbesondere anderer, Gang des Getriebes kann dabei insbesondere freilauffrei mit der Elektromaschine koppelbar sein.In this case, the drive train on an internal combustion engine, a transmission with two or more gears, an electric machine for wheel drive and at least one freewheel. It is, in particular only, at least a certain gear of the transmission can be decoupled by a freewheel of the electric machine. At least one, in particular other, gear of the transmission can be coupled in particular free-running with the electric machine.
Dadurch, dass lediglich einer oder mehrere bestimmte Gänge des Getriebes durch einen Freilauf von der Elektromaschine abkoppelbar sind und/oder einer oder mehrere andere Gänge des Getriebes freilauffrei mit der Elektromaschine koppelbar sind, kann vorteilhafterweise die mechanische Belastung des Freilauf des mindestens einen bestimmten, insbesondere höheren Gangs des Getriebes durch Schub-Zug-Wechsel, insbesondere beim Anfahren und/oder niedrigen Geschwindigkeiten vermieden werden. Dies ermöglicht es den Freilauf des mindestens einen bestimmten Gangs des Getriebes weniger stark auszulegen und/oder über eine längere Lebensdauer zu nutzen und Kosten in der Herstellung und/oder Instandhaltung des Antriebsstranges zu senken.The fact that only one or more specific gears of the transmission can be decoupled by a freewheel of the electric machine and / or one or more other gears of the transmission are freely coupled with the electric machine, advantageously, the mechanical load of the freewheel of at least one particular, in particular higher Gangs of the transmission by thrust-train change, especially when starting and / or low speeds are avoided. This makes it possible to design the freewheel of the at least one specific gear of the transmission less strong and / or to use over a longer life and to reduce costs in the production and / or maintenance of the drive train.
Durch die bestimmten Gänge mit Freilauf können vorteilhafterweise eine Rekuperation ohne Mitschleppen der anderen Komponenten des Getriebes und/oder der Verbrennungskraftmaschine ermöglicht und dadurch Schleppverluste minimiert und die Rekuperation verbessert werden.By certain gears with freewheel advantageously recuperation without entrainment of the other components of the transmission and / or the internal combustion engine allows, thereby minimizing drag losses and recuperation can be improved.
Durch die Elektromaschine kann das Fahrzeug bei geringen Geschwindigkeiten rein elektrisch angetrieben werden. Die maximal rein elektrisch erreichbaren Geschwindigkeit kann dabei insbesondere von der maximalen mechanischen Leistung der Elektromaschine abhängen und beispielsweise ≤ 50 km/h betragen.By the electric machine, the vehicle can be driven purely electrically at low speeds. The maximum achievable purely electrically speed may in particular depend on the maximum mechanical power of the electric machine and be, for example ≤ 50 km / h.
Beim Erreichen eines bestimmten Geschwindigkeitsgrenzwertes, wie der maximal rein elektrisch erreichbaren Geschwindigkeit y, beispielsweise von etwa 50 km/h, kann dann die Verbrennungskraftmaschine gestartet und insbesondere das Fahrzeug verbrennungsmotorisch angetrieben werden. Dabei kann der Antrieb rein verbrennungsmotorisch oder hybridisch erfolgen. Bei einem hybridischen Antrieb kann dabei die Gesamtbetriebsleistung durch die Elektromaschine erhöht beziehungsweise „geboostet“ werden.Upon reaching a certain speed limit, such as the maximum purely electrically achievable speed y, for example, of about 50 km / h, then the internal combustion engine can be started and in particular the vehicle can be driven by internal combustion engine. The drive can be purely internal combustion engine or hybrid. In the case of a hybrid drive, the overall operating power can be increased or "boosted" by the electric machine.
Die Elektromaschine kann insbesondere drehwirksam mit einem Antriebszahnrad, beispielsweise mit einem Radantriebszahnrad und/oder Radachsantriebszahnrad, insbesondere eines Differentials, verbunden sein. Zum Beispiel kann die Elektromaschine, insbesondere für ein Mild-Hybrid-Fahrzeug, als eine 48 V-Elektromaschine ausgeführt sein.The electric machine can in particular be rotationally effective with a drive gear, for example with a Radantriebszahnrad and / or Radachsantriebszahnrad, in particular a differential to be connected. For example, the electric machine, especially for a mild hybrid vehicle, may be implemented as a 48V electric machine.
Das Getriebe kann insbesondere einen ersten Gang und einen zweiten Gang und/oder einen dritten Gang und/oder einen vierten Gang und/oder einen fünften Gang und/oder einen sechsten Gang (oder auch noch mehr Gänge) und/oder einen Rückwärtsgang aufweisen. Dabei können die Gänge (hier auch als „Gangstufen“ bezeichenbar) insbesondere jeweils ein Festrad und ein durch ein Synchronisationselement feststellbares Losrad aufweisen. Anders ausgedrückt, jeder Gang bzw. jede Gangstufe kann insbesondere ein Festrad und ein mit einer Getriebewelle drehfest verbindbares Losrad aufweisen.The transmission may in particular have a first gear and a second gear and / or a third gear and / or a fourth gear and / or a fifth gear and / or a sixth gear (or even more gears) and / or a reverse gear. In this case, the gears (here also referred to as "gear stages" markable) in particular each have a fixed gear and a lockable by a synchronization element idler gear. In other words, each gear or each gear stage may in particular have a fixed gear and a idler gear rotatably connected to a transmission shaft.
Das Getriebe kann insbesondere eine Getriebeeingangswelle und mindestens eine Triebwelle aufweisen. In einer speziellen Ausgestaltung kann das Getriebe zwei oder mehr Triebwellen aufweisen. Den zwei oder mehr Triebwellen können dabei insbesondere unterschiedliche Gänge zugeordnet sein. Oder auch umgekehrt ausgedrückt: Beispielsweise kann eine erste Triebwelle dem ersten und/oder zweiten Gang und/oder eine zweite Triebwelle dem dritten und/oder vierten und/oder fünften und/oder sechsten Gang und/oder eine dritte Triebwelle dem Rückwärtsgang zugeordnet sein. Die Festräder der Gänge können dabei auf der gleichen Welle, beispielsweise der Getriebeeingangswelle, oder verteilt auf zwei oder mehr Wellen, wie der Getriebeeingangswelle und/oder der mindestens einen Triebwelle, beispielsweise der ersten und/oder zweiten und/oder dritten Triebwelle, angeordnet sein.The transmission may in particular have a transmission input shaft and at least one drive shaft. In a specific embodiment, the transmission may have two or more drive shafts. The two or more drive shafts may in particular be assigned different gears. Or, conversely, a first drive shaft may be associated with the first and / or second gear and / or a second drive shaft with the third and / or fourth and / or fifth and / or sixth gear and / or a third drive shaft with the reverse gear. The fixed gears of the gears can be arranged on the same shaft, for example the transmission input shaft, or distributed on two or more shafts, such as the transmission input shaft and / or the at least one drive shaft, for example, the first and / or second and / or third drive shaft.
Die Triebwelle kann insbesondere ein Triebwellenabtriebszahnrad aufweisen. Beispielsweise kann die erste Triebwelle ein erstes Triebwellenabtriebszahnrad und/oder die zweite Triebwelle ein zweites Triebwellenabtriebszahnrad und/oder die dritte Triebwelle ein drittes Triebwellenabtriebszahnrad aufweisen. Das Triebwellenabtriebszahnrad, beispielsweise das erste Triebwellenabtriebszahnrad und/oder das zweite Triebwellenabtriebszahnrad und/oder das dritte Triebwellenabtriebszahnrad, kann insbesondere im Eingriff mit dem Antriebszahnrad, beispielsweise mit dem Radantriebszahnrad und/oder Achsantriebszahnrad, insbesondere des Differentials, stehen.The drive shaft may in particular have a drive shaft output gear. For example, the first drive shaft may have a first drive shaft output gear and / or the second drive shaft may have a second drive shaft output gear and / or the third drive shaft may have a third drive shaft output gear. The drive shaft output gear, for example the first drive shaft output gear and / or the second drive shaft output gear and / or the third drive shaft output gear, may in particular be in engagement with the drive gear, for example with the Radantriebszahnrad and / or final drive gear, in particular the differential stand.
Insbesondere kann das Getriebe als ein Stufengetriebe ausgeführt sein.In particular, the transmission can be designed as a stepped transmission.
In einer bevorzugten Ausgestaltung ist mindestens ein niedriger Gang des Getriebes, beispielsweise der erste Gang und/oder der zweite Gang des Getriebes, freilauffrei mit der Elektromaschine koppelbar.In a preferred embodiment, at least one lower gear of the transmission, for example the first gear and / or the second gear of the transmission, can be coupled to the electric machine free-running.
Bei einer Rekuperation durch die Elektromaschine während einer Fahrt in einem niedrigen Gang, wie dem ersten und/oder zweiten(und/oder gegebenenfalls dritten Gang) und/oder Rückwärtsgang, ist üblicherweise die kinetische Energie gering und damit in der Regel lediglich eine geringe oder sogar keine Rekuperation zu erwarten. Daher ist hierbei auch ein durch einen Freilauf erzielbarer positiver Effekt durch eine Schleppverlustreduzierung bei der Rekuperation gering und kann in der Regel starke Verschleißerscheinungen des Freilaufs durch hohe mechanische Belastungen durch Schub-Zug-Wechsel in diesen Gängen kaum oder nicht aufwiegen.In a recuperation by the electric machine during a journey in a low gear, such as the first and / or second (and / or optionally third gear) and / or reverse, usually the kinetic energy is low and thus usually only a small or even no recuperation expected. Therefore, this is also a recoverable by a freewheel positive effect by a drag loss reduction during recuperation low and can usually hardly or not outweigh strong signs of wear of the freewheel through high mechanical loads by push-pull change in these gears.
Der mindestens eine bestimmte Gang kann insbesondere ein höherer Gang des Getriebes sein. Insbesondere kann daher dabei mindestens ein bestimmter, höherer Gang des Getriebes, beispielsweise der dritte Gang und/oder der vierte Gang und/oder der fünfte Gang und/oder der sechste Gang des Getriebes, durch einen Freilauf von der Elektromaschine abkoppelbar sein.The at least one specific gear can be in particular a higher gear of the transmission. In particular, therefore, at least one specific, higher gear of the transmission, for example the third gear and / or the fourth gear and / or the fifth gear and / or the sixth gear of the transmission, can be decoupled from the electric machine by a freewheel.
Bei einer Rekuperation durch die Elektromaschine während einer Fahrt in einem höheren Gang, wie dem dritten, vierten, fünften und/oder sechsten Gang, ist üblicherweise die kinetische Energie und damit die Rekuperation am höchsten, weshalb hierbei eine Vermeidung von Schleppverlusten durch einen Freilauf von besonderem Vorteil ist.In a recuperation by the electric machine during a trip in a higher gear, such as the third, fourth, fifth and / or sixth gear, usually the kinetic energy and thus the recuperation is highest, which is why this avoidance of drag losses by a freewheel of particular Advantage is.
Insbesondere im Fall eines größeren Fahrzeugs, kann der mindestens eine bestimmte Gang, welcher durch einen Freilauf von der Elektromaschine abkoppelbar ist, gegebenenfalls jedoch lediglich ein mittlerer Gang und insbesondere nicht der höchste Gang des Getriebes sein.In particular, in the case of a larger vehicle, the at least one specific gear, which can be decoupled from the electric motor by a freewheel, but possibly only a middle gear and in particular not the highest gear of the transmission.
In einer weiteren Ausgestaltung ist mindestens ein Festrad eines bestimmten Gangs mit einem Freilauf ausgestattet. Beispielsweise können zwei oder mehr Festräder unterschiedlicher bestimmter Gänge jeweils mit einem Freilauf ausgestattet sein.In a further embodiment, at least one fixed gear of a certain gear is equipped with a freewheel. For example, two or more fixed wheels of different specific gears can each be equipped with a freewheel.
In einer alternativen oder zusätzlichen, weiteren Ausgestaltung ist mindestens ein Synchronelement, beispielsweise mindestens ein Synchronkörper, insbesondere eines Losrades, eines bestimmten Gangs und/oder von unterschiedlichen bestimmten Gängen mit einem Freilauf ausgestattet. Beispielsweise können zwei oder mehr Synchronelemente, beispielsweise Synchronkörper, unterschiedlicher bestimmter Gänge jeweils mit einem Freilauf ausgestattet sein.In an alternative or additional, further embodiment, at least one synchronizing element, for example at least one synchronizing body, in particular a loose wheel, a certain gear and / or of different specific gears is equipped with a freewheel. For example, two or more synchronous elements, for example synchronizer bodies, of different specific gears can each be equipped with a freewheel.
In einer alternativen oder zusätzlichen, weiteren Ausgestaltung ist mindestens eine bestimmte Triebwelle, von zwei oder mehr unterschiedlichen Gängen zugeordneten Triebwellen mit einem Freilauf ausgestattet. Dabei kann insbesondere ein Triebwellenabtriebszahnrad der mindestens einen bestimmten Triebwelle mit einem Freilauf ausgestattet sein. Gegebenenfalls können zwei oder mehr Triebwellen, welche unterschiedlichen bestimmten Gängen zugeordnet sind, insbesondere deren Triebwellenabtriebszahnräder, jeweils mit einem Freilauf ausgestattet sein.In an alternative or additional, further embodiment, at least one particular drive shaft, of two or more different gears associated drive shafts equipped with a freewheel. In particular, a Triebwellenabtriebszahnrad the at least one specific drive shaft to be equipped with a freewheel. Optionally, two or more drive shafts, which are assigned to different specific gears, in particular their drive shaft output gears, each be equipped with a freewheel.
In einer speziellen Ausgestaltung ist der dritte Gang und/oder der vierte Gang und/oder der fünfte Gang und/oder der sechste Gang des Getriebes durch einen Freilauf von der Elektromaschine abkoppelbar.In a specific embodiment, the third gear and / or the fourth gear and / or the fifth gear and / or the sixth gear of the transmission can be decoupled from the electric machine by a freewheel.
In einer speziellen Ausgestaltung ist der erste Gang und/oder der zweite Gang des Getriebes freilauffrei mit der Elektromaschine koppelbar.In a specific embodiment, the first gear and / or the second gear of the transmission can be coupled with the electric machine free-running.
In einer weiteren Ausgestaltung ist das Getriebe als ein Handschaltgetriebe ausgeführt. So kann der Fahrer des Fahrzeugs den Gang im verbrennungsmotorischen Betrieb des Fahrzeugs selbst bestimmen.In a further embodiment, the transmission is designed as a manual transmission. Thus, the driver of the vehicle can determine the course in the internal combustion engine operation of the vehicle itself.
In einer weiteren Ausgestaltung ist die Elektromaschine zum Vorderachsenradantrieb und/oder Hinterachsenradantrieb ausgelegt (bzw. zur Rekuperation durch den entsprechenden Achsantrieb).In a further embodiment, the electric machine is designed for Vorderachsradantrieb and / or Hinterachsradantrieb (or for recuperation by the corresponding final drive).
Weiterhin kann der Antriebsstrang eine Traktionsbatterie, beispielsweise eine 48 V-Batterie, aufweisen.Furthermore, the powertrain may include a traction battery, such as a 48V battery.
In einer weiteren Ausgestaltung weist der Antriebsstrang weiterhin einen Riemenstartergenerator oder eine Lichtmaschine in Kombination mit einem Verbrennungsmaschinenstarter auf. Beispielsweise kann für ein Mild-Hybrid-Fahrzeug der Riemenstartergenerator ein 48 V- Riemenstartergenerator und/oder die Lichtmaschine eine 12 V-Lichtmaschine in Kombination mit einem 12 V-Verbrennungsmaschinenstarter als Verbrennungsmaschinenstarter sein. Der Verbrennungsmaschinenstarter kann beispielsweise mit einer Starterbatterie, beispielsweise einer 12 V-Batterie, und/oder der Elektromaschinenantriebsbatterie, beispielsweise einer 48 V-Batterie, gegebenenfalls über einen DC/DC-Wandler, betreibbar sein.In a further embodiment, the drive train further comprises a belt starter generator or an alternator in combination with an internal combustion engine starter. For example, for a mild hybrid vehicle, the belt starter generator may be a 48V belt starter generator and / or the alternator may be a 12V alternator in combination with a 12V engine starter as an engine starter. The internal combustion engine starter may, for example, be operable with a starter battery, for example a 12 V battery, and / or the electric machine drive battery, for example a 48 V battery, optionally via a DC / DC converter.
In einer weiteren Ausgestaltung ist der Antriebsstrang für ein Mild-Hybrid-Fahrzeug ausgelegt. Beispielsweise kann der Antriebsstrang als 48 V-Mild-Hybrid, insbesondere mit Handschaltgetriebe, ausgelegt sein.In a further embodiment, the drive train is designed for a mild hybrid vehicle. For example, the drive train can be designed as a 48 V mild hybrid, in particular with a manual transmission.
