For such hybrid drives from an internal combustion engine and (at least) an electrical machine, which can be operated as a motor and / or generator, there are different structural variants. On the one hand, parallel hybrid drives are known in which the internal combustion engine and the electric machine (can) drive the vehicle mechanically together in ferry operation and the electric machine is operated as a generator in braking operation and / or to charge an energy store. In this arrangement, the drive powers of the internal combustion engine and the electric machine complement each other, but the internal combustion engine cannot be operated with optimized efficiency because of its dependence on the driving speed.
Alternativ dazu sind serielle Hybridantriebe bekannt, bei welchen die Verbrennungskraftmaschine eine erste elektrische Maschine als Generator zum Aufladen des Energiespeichers an treibt und alleine eine zweite elektrische Maschine als Motor das Fahrzeug antreibt, wozu sie auf den Energiespeicher zu greift, welchen sie im Bremsbetrieb meist zusätzlich auflädt. Dadurch kann die Verbrennungskraftmaschine optimiert betrieben werden, jedoch sind Maschinen mit in Summe höherer Gesamtleis tung zu verbauen. Alternatively, serial hybrid drives are known in which the internal combustion engine drives a first electrical machine as a generator to charge the energy store and a second electrical machine alone drives the vehicle as a motor, for which purpose it accesses the energy store, which it usually additionally charges during braking . As a result, the internal combustion engine can be operated in an optimized manner However, machines with a higher total output are to be installed.
Ein leistungsverzweigender Hybridantrieb als dritte An triebsvariante umfasst eine Verbrennungskraftmaschine und zwei elektrische Maschinen, welche allesamt über ein meist komplexes Getriebe mechanisch Zusammenwirken, wobei eine der beiden e- lektrischen Maschinen vorrangig generatorisch und die andere vorrangig motorisch betrieben wird. Der in diesem Fall komple xere und raumgreifende mechanische Aufbau ermöglicht - bei ent sprechender Steuerung - eine höhere Flexibilität im Energie flussmanagement. Ein Antriebsstrang der einleitend genannten Art ist für einen leistungsverzweigenden Hybridantrieb bei spielsweise aus der Schrift DE 10158 536 B4 bekannt. A power-split hybrid drive as a third drive variant comprises an internal combustion engine and two electrical machines, all of which interact mechanically via a mostly complex transmission, one of the two electrical machines being operated primarily as a generator and the other primarily as a motor. In this case, the more complex and space-consuming mechanical structure enables - with the appropriate control - greater flexibility in energy flow management. A drive train of the type mentioned in the introduction is known for a power-split hybrid drive for example from DE 10158 536 B4.
Allen genannten Antriebsvarianten ist gemeinsam, dass im Fahrzeug sowohl ein Kraftstoffbehälter für die Verbrennungs kraftmaschine als auch ein elektrischer Energiespeicher für die zumindest eine elektrische Maschine unterzubringen sind. Kraft stoffbehälter werden bei Landfahrzeugen meist im Bereich des hinteren Fahrwerks, z.B. unter einer Rücksitzbank od.dgl., ver baut; für den elektrischen Energiespeicher verbleibt dann ein Platz im bzw. unter dem Kofferraum bzw. im Fußraum unter den Fahrgästen. Dadurch wird jeweils der Kofferraum oder der Fahr gastraum eingeschränkt; ferner sitzt der Energiespeicher an ei ner bei einem Heck- oder Seitenaufprall weniger gut geschützten Stelle, sodass in einem solchen Fall eine Zellbeschädigung mit ausfließendem Elektrolyt und sogar ein Brand des geladenen E- nergiespeichers drohen. Die Vielzahl separater Bestandteile er schwert den Einbau, steht der Modularität solcher Antriebskon zepte entgegen und führt zu komplexen Wegen für die Kraftstoff versorgung und für elektrische Leitungen. All of the drive variants mentioned have in common that both a fuel tank for the internal combustion engine and an electrical energy store for the at least one electrical machine must be accommodated in the vehicle. Fuel tanks are mostly used in land vehicles in the area of the rear chassis, e.g. under a rear bench seat or the like., Ver builds; For the electrical energy store there remains a place in or under the trunk or in the footwell under the passengers. As a result, the trunk or the passenger compartment is restricted in each case; Furthermore, the energy store is located in a location that is less well protected in the event of a rear or side impact, so that in such a case there is a risk of cell damage with escaping electrolyte and even a fire to the charged energy store. The large number of separate components makes installation difficult, stands in the way of the modularity of such drive concepts and leads to complex paths for the fuel supply and for electrical lines.
Bei Wasserfahrzeugen ist der für Kraftstoffbehälter und elektrische Energiespeicher zur Verfügung stehende Raum meist weniger eingeschränkt; dennoch erfordert eine Verteilung von Antriebsstrang, Kraftstoffbehälter und elektrischem Energie speicher einen höheren Aufwand beim Einbau und führt zu komple- xen Wegen für den Kraftstoff und für die elektrischen Leitun gen. In the case of watercraft, the space available for fuel tanks and electrical energy storage devices is usually less restricted; Nevertheless, the distribution of the drive train, fuel tank and electrical energy storage requires more effort during installation and leads to complex xen ways for the fuel and for the electrical lines.
Die Erfindung setzt sich zum Ziel, einen besonders sicher und flexibel einsetzbaren Antrieb für ein Fahrzeug zu schaffen, welcher einfach verbaut werden kann und kurze Kraftstoffleitun- gen und/oder elektrische Leitungen ermöglicht. The aim of the invention is to create a drive for a vehicle that can be used particularly safely and flexibly, which can be easily installed and which enables short fuel lines and / or electrical lines.
Dieses Ziel wird gemäß einem ersten Aspekt der Erfindung mit einem Antriebsstrang der einleitend genannten Art erreicht, welcher sich dadurch auszeichnet, dass die Verbindungswelle mit Radialabstand in einem Rohr des Antriebsstrangs aufgenommen ist, wobei in dem durch den Radialabstand zwischen dem Rohr und der Verbindungswelle ausgebildeten Ringraum ein Kraftstoffbe hälter und/oder ein elektrischer Energiespeicher aufgenommen ist. According to a first aspect of the invention, this object is achieved with a drive train of the type mentioned in the introduction, which is characterized in that the connecting shaft is received with a radial spacing in a tube of the drive train, with the annular space formed by the radial spacing between the pipe and the connecting shaft a fuel tank and / or an electrical energy store is added.
Ein Antriebsstrang dieser Art ermöglicht durch seine zent ral gebündelte Anordnung einen hervorragenden Schutz des emp findlichen Kraftstoffbehälters bzw. des empfindlichen elektri schen Energiespeichers. Ferner ist dadurch eine besonders güns tige Gewichtsverteilung und gute Raumausnutzung des Antriebs strangs in dem Fahrzeug erzielbar. Überdies kann ein derartig aufgebauter Antriebsstrang besonders einfach als Gesamtmodul in unterschiedliche Fahrzeuge eingebaut und mit geringem Aufwand flexibel an unterschiedliche Erfordernisse angepasst werden. Je nach Anzahl elektrischer Maschinen sind verschiedene hybride Antriebsvarianten erzielbar. Insgesamt sind durch die Anordnung des Kraftstoffbehälters und/oder der elektrischen Energiespei cher in unmittelbarer Nähe der Verbrennungskraftmaschine und der elektrischen Maschine die jeweiligen Längen der zugehörigen Energieleitungen gering und können die Leitungen in Axialrich tung des Antriebsstrangs weitgehend geradlinig geführt werden, sodass sich besonders einfache Wege ergeben. Es versteht sich, dass in dem Ringraum weitere Elemente des Antriebs, z.B. Leis tungselektronik und/oder eine Regelung für die elektrische Ma schine untergebracht sein kann. In einer vorteilhaften Ausführungsform ist der Ringraum in zwei oder mehrere Kammern unterteilt. Dies ermöglicht eine be sonders flexible Nutzung des Ringraums für unterschiedliche E- nergiespeicher, d.h. für einen Kraftstoffbehälter bzw. für e- lektrische Energiespeicher in beliebiger Aufteilung. Ferner er leichtert eine solche Unterteilung den Einbau weiterer An triebselemente, z.B. der Leistungselektronik und/oder Regelung der elektrischen Maschine. A drive train of this type enables excellent protection of the sensitive fuel tank or the sensitive electrical energy storage device due to its centrally bundled arrangement. Furthermore, a particularly favorable weight distribution and good space utilization of the drive train in the vehicle can thereby be achieved. In addition, a drive train constructed in this way can be installed particularly easily as an overall module in different vehicles and flexibly adapted to different requirements with little effort. Different hybrid drive variants can be achieved depending on the number of electrical machines. Overall, due to the arrangement of the fuel tank and / or the electrical energy storage device in the immediate vicinity of the internal combustion engine and the electrical machine, the respective lengths of the associated power lines are small and the lines can be routed largely in a straight line in the axial direction of the drive train, resulting in particularly simple routes . It goes without saying that further elements of the drive, for example power electronics and / or a control system for the electrical machine, can be accommodated in the annular space. In an advantageous embodiment, the annular space is divided into two or more chambers. This enables a particularly flexible use of the annular space for different energy stores, ie for a fuel tank or for electrical energy stores in any distribution. Furthermore, such a subdivision makes it easier to install additional drive elements, such as the power electronics and / or control of the electrical machine.
Ein besonders einfacher Aufbau ergibt sich, wenn die Kupp lung zwischen der Ausgangswelle und der Verbindungswelle liegt, wobei die elektrische Maschine auf die Verbindungswelle aufge steckt ist. Dabei kann die elektrische Maschine als Hohlwellen maschine an der der Ausgangswelle oder dem Endantrieb zugewand ten Seite der Verbindungswelle auf diese aufgesteckt sein. A particularly simple structure is obtained when the hitch is between the output shaft and the connecting shaft, the electrical machine being plugged onto the connecting shaft. The electric machine can be plugged onto the connecting shaft as a hollow shaft machine on the side of the connecting shaft facing the output shaft or the final drive.
In einer bevorzugten Ausführungsform des Antriebsstrangs ist die elektrische Maschine auf die Verbindungswelle an ihrer der Ausgangswelle zugewandten Seite aufgesteckt und umfasst der Antriebsstrang eine mit dem Endantrieb verbundene zweite elekt rische Maschine und eine zweite Kupplung zum lösbaren Verbinden der zweiten elektrischen Maschine mit der Verbindungswelle. Dies ermöglicht eine höhere Gesamtleistung des Antriebsstrangs und eine flexible Verteilung der Antriebsleistung. Auch bleiben die jeweiligen Längen der Energieleitungen weiterhin gering, besonders die elektrischen Leitungen der zu den beiden dem Ringraum unmittelbar benachbarten elektrischen Maschinen, was auch Gewicht spart, umso mehr, wenn die Leistungselektronik und Regelung für die elektrischen Maschinen ebenfalls in dem Ring raum angeordnet sind. In a preferred embodiment of the drive train, the electrical machine is plugged onto the connecting shaft on its side facing the output shaft and the drive train comprises a second electrical machine connected to the final drive and a second coupling for releasably connecting the second electrical machine to the connecting shaft. This enables a higher total power of the drive train and a flexible distribution of the drive power. The respective lengths of the power lines remain small, especially the electrical lines of the two electrical machines immediately adjacent to the annulus, which also saves weight, all the more if the power electronics and control for the electrical machines are also arranged in the annulus.
Besonders günstig ist dabei, wenn die beiden Kupplungen voneinander unabhängig schaltbar sind. Ebenfalls günstig ist, wenn die beiden elektrischen Maschinen voneinander unabhängig regelbar sind. Durch einfaches Schalten der Kupplungen bzw. durch die Regelung der elektrischen Maschinen sind so alle hyb riden Antriebsvarianten unmittelbar erzielbar, d.h. serieller, paralleler und leistungsverzweigender Hybridbetrieb, ohne von der strukturellen Einfachheit und dem geringen Raumbedarf des Antriebsstrangs abzugehen. It is particularly advantageous if the two clutches can be switched independently of one another. It is also advantageous if the two electrical machines can be regulated independently of one another. By simply switching the clutches or by regulating the electrical machines, all hybrid drive variants can be achieved directly, ie serial, parallel and power-split hybrid operation without the structural simplicity and the small footprint of the drive train.
In einer vorteilhaften Variante umfasst der Endantrieb ein Achsgetriebe und zwei Antriebswellen für ein Landfahrzeug. So mit ergibt sich eine besonders einfache Struktur für Landfahr zeuge. Dabei ist besonders günstig, wenn der Endantrieb ferner ein dem Achsgetriebe vorgelagertes Wechselgetriebe umfasst. Auf diese Weise kann die Maschinendrehzahl von der Fahrgeschwindig keit zumindest teilweise entkoppelt werden, um so einen günsti gen Wirkungsgrad der Maschinen und dabei die für den Antrieb des Fahrzeugs erforderliche Antriebsleistung zu erzielen. In an advantageous variant, the final drive comprises an axle drive and two drive shafts for a land vehicle. This results in a particularly simple structure for land vehicles. It is particularly advantageous if the final drive further comprises a change gear upstream of the axle drive. In this way, the machine speed can be at least partially decoupled from the Fahrgeschwindig speed in order to achieve a favorable efficiency of the machines and thereby the drive power required to drive the vehicle.
In einer alternativen oder sogar ergänzenden Variante um fasst der Endantrieb eine Antriebsachse und einen von dieser angetriebenen Propeller für ein Wasserfahrzeug. Wiederum ergibt sich daraus eine besonders einfache Struktur für den Antriebs strang. In an alternative or even a supplementary variant, the final drive comprises a drive axle and a propeller for a watercraft driven by this. Again, this results in a particularly simple structure for the drive train.
In einem zweiten Aspekt schafft die Erfindung einen Zent ralrohrrahmen für ein Fahrzeug, insbesondere ein Landfahrzeug, welcher zur Verankerung eines vorderen und eines hinteren Fahr werks des Fahrzeugs und eines Fahrzeugaufbaus ausgebildet ist und sich dadurch auszeichnet, dass er einen Antriebsstrang der vorgenannten Art enthält, wobei die Verbrennungskraftmaschine und das Rohr tragende Elemente des Zentralrohrrahmens sind. Die Vorteile des Antriebsstrangs, insbesondere sein geringer Raum bedarf, seine flexible Einsetzbarkeit, seine Modularität und seine mechanische Struktur, werden dadurch gewinnbringend für den gleichermaßen flexibel einsetzbaren Zentralrohrrahmen nutz bar gemacht. Der Antriebsstrang, insbesondere sein Kraftstoff behälter bzw. die elektrischen Energiespeicher, sind im Zent ralrohrrahmen besonders gut geschützt. Zugleich entfallen durch die Nutzung der Verbrennungskraftmaschine und des Rohrs des An triebsstrangs als tragende Elemente des Zentralrohrrahmens zu sätzliche separate Elemente und damit deren Gewicht und der da für erforderliche Bauraum. Besonders günstig ist, wenn der Zentralrohrrahmen durch den Motorblock der Verbrennungskraftmaschine, ein an dem Motor block verankertes erstes Gehäuse, das Rohr, welches an dem ers ten Gehäuse verankert ist, und ein an dem Rohr verankertes zweites Gehäuse gebildet ist, wobei die elektrische Maschine auf die Verbindungswelle aufgesteckt und das erste Gehäuse zur Aufnahme der Kupplung und der elektrischen Maschine ausgebildet ist, und wobei das zweite Gehäuse zur Aufnahme einer zweiten elektrischen Maschine des Antriebsstrangs, eines von dieser ge speisten Wechselgetriebes mit angeschlossenem Achsgetriebe des Endantriebs und einer zweiten Kupplung zum lösbaren Verbinden der Verbindungswelle mit der zweiten elektrischen Maschine aus gebildet ist. So entfallen separate tragende Elemente für den Zentralrohrrahmen; dieser ist stabil ausführbar und dabei ge wicht- und raumsparend und für eine Vielzahl verschiedener Fahrzeuge, insbesondere Landfahrzeuge, verwendbar. Durch ge ringfügige Änderungen kann ein solcher Zentralrohrrahmen ferner flexibel und unter Beibehaltung der Vorteile und Wirkungsweise an die jeweiligen Erfordernisse unterschiedlicher Fahrzeuge an gepasst werden. In a second aspect, the invention provides a central tubular frame for a vehicle, in particular a land vehicle, which is designed to anchor a front and a rear chassis of the vehicle and a vehicle body and is characterized in that it contains a drive train of the aforementioned type, wherein the internal combustion engine and the pipe are elements of the central tubular frame that support the pipe. The advantages of the drive train, in particular its small footprint, its flexible usability, its modularity and its mechanical structure, are thereby made profitable for the equally flexible central tube frame. The drive train, in particular its fuel tank or the electrical energy storage, are particularly well protected in the central tube frame. At the same time, due to the use of the internal combustion engine and the tube of the drive train as supporting elements of the central tubular frame, additional separate elements and thus their weight and the space required for it are eliminated. It is particularly advantageous if the central tubular frame is formed by the engine block of the internal combustion engine, a first housing anchored to the engine block, the tube, which is anchored to the first housing, and a second housing anchored to the tube, the electric machine being on the connecting shaft is plugged on and the first housing is designed to accommodate the clutch and the electric machine, and the second housing to accommodate a second electric machine of the drive train, a gearbox fed by this with a connected axle drive of the final drive and a second clutch for releasable connection the connecting shaft is formed from the second electrical machine. Separate load-bearing elements for the central tubular frame are no longer necessary; this can be carried out in a stable manner and it saves weight and space and can be used for a variety of different vehicles, in particular land vehicles. By making minor changes, such a central tube frame can also be adapted flexibly and while maintaining the advantages and mode of operation to the respective requirements of different vehicles.
Ein besonders günstige Gewichtsverteilung im Fahrzeug ist dabei erzielbar, wenn das zweite Gehäuse zum Verankern und der Endantrieb zum Antreiben des hinteren Fahrwerks des Fahrzeugs ausgebildet sind. Der Zentralrohrrahmen erstreckt sich so vom hinteren Fahrwerk in Richtung der Fahrzeugfront. A particularly favorable weight distribution in the vehicle can be achieved if the second housing is designed for anchoring and the final drive for driving the rear chassis of the vehicle. The central tubular frame extends from the rear chassis in the direction of the front of the vehicle.
Ferner ist vorteilhaft, wenn der Motorblock der Verbren nungskraftmaschine an seiner dem Rohr abgewandten Seite zum Verankern des vorderen Fahrwerks des Fahrzeugs ausgebildet ist. Das hilft, zusätzliche Bauteile einzusparen. It is also advantageous if the engine block of the internal combustion engine is designed on its side facing away from the pipe for anchoring the front chassis of the vehicle. This helps to save additional components.
Alternativ dazu kann der Zentralrohrrahmen einen zweiarmi gen Träger zum Verankern des vorderen Fahrwerks des Fahrzeugs umfassen, wobei jeder Trägerarm an jeweils einer Lateralseite des ersten Gehäuses verankert ist und die Trägerarme den Motor block lateral umgreifen. Dies ermöglicht eine Teilentkopplung der Verankerung des vorderen Fahrwerks von der Verbrennungs- kraftmaschine, indem die im Fährbetrieb am vorderen Fahrwerk auftretenden Kräfte über die Trägerarme auf das erste Gehäuse und somit näher zur Fahrzeugmitte auf den Zentralrohrrahmen ü- bertragen werden. Alternatively, the central tube frame can comprise a two-arm carrier for anchoring the front chassis of the vehicle, each carrier arm being anchored on a respective lateral side of the first housing and the carrier arms laterally encompassing the engine block. This enables a partial decoupling of the anchoring of the front landing gear from the combustion engine, in that the forces occurring on the front chassis during ferry operation are transmitted via the support arms to the first housing and thus closer to the center of the vehicle on the central tubular frame.
Günstig ist dabei, wenn an den Trägerarmen ein drittes Ge häuse verankert ist, welches von der dem Rohr abgewandten Seite des Motorblocks beabstandet und zur Aufnahme einer dritten e- lektrischen Maschine und eines weiteren Achsgetriebes für das vordere Fahrwerk des Fahrzeugs ausgebildet ist. Alternativ dazu ist an der dem Rohr abgewandten Seite des Motorblocks ein drit tes Gehäuse verankert, welches zur Aufnahme einer dritten e- lektrischen Maschine und eines weiteren Achsgetriebes zum An treiben des vorderen Fahrwerks des Fahrzeugs ausgebildet ist. Damit umfasst der Zentralrohrrahmen eine weitere, von den ande ren unabhängige elektrische Maschine, welche als Antriebsmotor bzw. als Bremsgenerator auf das vordere Fahrwerk wirkt. Die dritte elektrische Maschine kann dabei z.B. von dem im Ringraum angeordneten elektrischen Energiespeicher gespeist werden bzw. diesen speisen. Insgesamt ermöglicht dies einen sehr kompakten Zentralrohrrahmen mit komplettem integriertem Antriebsstrang und Allradantrieb in Hybridtechnik. It is advantageous if a third housing is anchored to the support arms, which is spaced from the side of the engine block facing away from the pipe and designed to accommodate a third electrical machine and a further axle drive for the front chassis of the vehicle. Alternatively, a third housing is anchored on the side of the engine block facing away from the pipe, which housing is designed to accommodate a third electrical machine and a further axle drive for driving the front chassis of the vehicle. The central tubular frame thus includes another electrical machine that is independent of the others and acts as a drive motor or as a brake generator on the front chassis. The third electrical machine can, for example, be fed by the electrical energy store arranged in the annulus or feed it. Overall, this enables a very compact central tubular frame with a completely integrated drive train and all-wheel drive in hybrid technology.
Hinsichtlich weiterer Vorteile und Ausführungsformen des Zentralrohrrahmes wird auf die vorangegangenen Ausführungen zu dem Antriebsstrang verwiesen. With regard to further advantages and embodiments of the central tubular frame, reference is made to the preceding statements on the drive train.
Die Erfindung wird nachfolgend anhand von in den beige schlossenen Zeichnungen dargestellten Ausführungsbeispielen nä her erläutert.

Die Fig. 1 und 2 zeigen jeweils ein Fahrgestell 1 eines Fahrzeugs (hier: eines Landfahrzeugs). Die Fahrgestelle 1 haben jeweils einen Zentralrohrrahmen 2, an welchen ein vorderes und ein hinteres Fahrwerk 3, 4 verankert ist. Der Zentralrohrrahmen1 and 2 each show a chassis 1 of a vehicle (here: a land vehicle). The chassis 1 each have a central tubular frame 2 on which a front and a rear chassis 3, 4 is anchored. The central tubular frame
2 hat optionale Verankerungspunkte 5 für einen Fahrzeugaufbau (nicht dargestellt) und enthält einen Antriebsstrang 6. Der An triebsstrang 6 umfasst eine Verbrennungskraftmaschine 7 mit ei ner Ausgangswelle 8. Die Verbrennungskraftmaschine 7 ist im dargestellten Beispiel ein Hubkolbenmotor; sie könnte alterna tiv ein Rotationskolbenmotor, eine Gasturbine od.dgl. sein, da bei ist die Ausgangswelle 8 beispielsweise eine Kurbelwelle des Hubkolbenmotors, eine Exzenterwelle des Rotationskolbenmotors, eine Turbinenwelle der Gasturbine oder eine Welle am Ausgang eines in die Verbrennungskraftmaschine integrierten oder daran angebauten Getriebes. 2 has optional anchoring points 5 for a vehicle body (not shown) and contains a drive train 6. The drive train 6 comprises an internal combustion engine 7 with an output shaft 8. The internal combustion engine 7 is a reciprocating engine in the example shown; they could alterna tively a rotary piston engine, a gas turbine or the like. because the output shaft 8 is, for example, a crankshaft of the reciprocating engine, an eccentric shaft of the rotary piston engine, a turbine shaft of the gas turbine or a shaft at the output of a transmission integrated into the internal combustion engine or attached to it.
Der Antriebsstrang 6 umfasst ferner einen Endantrieb 9 für das Fahrzeug und eine Verbindungswelle 10 zwischen der Aus gangswelle 8 und dem Endantrieb 9, sowie eine elektrische Ma schine 11 und eine Kupplung 12. Die Kupplung 12 verbindet die elektrische Maschine 11 lösbar mit der Ausgangswelle 8. Die Ausgangswelle 8, die Verbindungswelle 10 und die elektrische Maschine 11 sind im Wesentlichen koaxial zueinander am An triebsstrang 6 angeordnet; „im Wesentlichen" bedeutet in diesem Zusammenhang, dass auch ein Kardangelenk mit geringem Gelenk winkel und/oder ein geringfügiger axialer Versatz zwischen die sen drei Elementen bestehen kann. The drive train 6 further comprises a final drive 9 for the vehicle and a connecting shaft 10 between the output shaft 8 and the final drive 9, as well as an electrical machine 11 and a coupling 12. The coupling 12 releasably connects the electrical machine 11 to the output shaft 8. The output shaft 8, the connecting shaft 10 and the electric machine 11 are arranged essentially coaxially to one another on the drive train 6; "Essentially" means in this Relation that a universal joint with a small joint angle and / or a slight axial offset between the three sen elements can exist.
In den dargestellten Beispielen liegt die Kupplung 12 zwi schen der Ausgangswelle 8 und der Verbindungswelle 10. Ferner ist die elektrische Maschine 11 als Hohlwellenmaschine auf die Verbindungswelle 10 aufgesteckt, u.zw. an der der Ausgangswelle 8 zugewandten Seite der Verbindungswelle 10; alternativ kann die elektrische Maschine 11 an der dem Endantrieb 9 zugewandten Seite der Verbindungswelle 10 auf diese aufgesteckt sein. Auch die Kupplung 12 kann, anstatt zwischen der Ausgangswelle 8 und der Verbindungswelle 10 zu liegen, an der dem Endantrieb 9 zu gewandten Seite der Verbindungswelle 10 jedoch zwischen elekt rische Maschine 11 und Verbrennungskraftmaschine 7 angeordnet sein, um die elektrische Maschine 11 (in diesem Fall: über die Verbindungswelle 10) mit der Ausgangswelle 8 lösbar zu verbin den. In the examples shown, the coupling 12 is between the output shaft 8 and the connecting shaft 10. Furthermore, the electric machine 11 is plugged onto the connecting shaft 10 as a hollow shaft machine, u.zw. on the side of the connecting shaft 10 facing the output shaft 8; alternatively, the electrical machine 11 can be plugged onto the connecting shaft 10 on the side of the connecting shaft 10 facing the final drive 9. The coupling 12, instead of being between the output shaft 8 and the connecting shaft 10, can also be arranged on the side of the connecting shaft 10 facing the final drive 9, however, between the electric machine 11 and the internal combustion engine 7 in order to connect the electric machine 11 (in this case : via the connecting shaft 10) with the output shaft 8 to releasably connect the.
In den gezeigten Beispielen umfasst der Antriebsstrang 6 eine optionale zweite elektrische Maschine 13, welche mit dem Endantrieb 9 verbunden ist; ferner umfasst der Antriebsstrang 6 an der dem Endantrieb 9 zugewandten Seite der Verbindungswelle 10 eine optionale zweite Kupplung 14, welche die zweite elekt rische Maschine 13 lösbar mit der Verbindungswelle 10 verbin det. Dabei ist die zweite elektrische Maschine 13 wieder im We sentlichem koaxial zur Verbindungswelle 10. In the examples shown, the drive train 6 comprises an optional second electrical machine 13, which is connected to the final drive 9; Furthermore, the drive train 6 comprises, on the side of the connecting shaft 10 facing the final drive 9, an optional second coupling 14 which releasably connects the second electric machine 13 to the connecting shaft 10. The second electrical machine 13 is again essentially coaxial with the connecting shaft 10.
Sind die genannte eine (im Folgenden auch: „erste") Kupp lung 12 und die zweite Kupplung 14 voneinander unabhängig schaltbar, wie dies optional der Fall ist, kann die genannte eine (im Folgenden auch: „erste") elektrische Maschine 11 mit der Ausgangswelle 8 lösbar verbunden werden, u.zw. unabhängig vom Lösen oder Verbinden der zweiten elektrischen Maschine 13 mit der Verbindungswelle 10 durch die zweite Kupplung 14. Sind ferner die erste und zweite elektrische Maschine 11, 13 vonein ander unabhängig regelbar, d.h. auch voneinander unabhängig je weils in einen motorischen oder generatorischen Betriebszustand überführbar, wie dies optional der Fall ist, kann der Antrags strang 6 beliebige unterschiedliche Betriebszustände einnehmen: If the mentioned one (hereinafter also: "first") clutch 12 and the second clutch 14 can be switched independently of one another, as is optionally the case, the mentioned one (hereinafter also: "first") electrical machine 11 can be connected to the Output shaft 8 can be detachably connected, u.zw. Independent of the loosening or connection of the second electrical machine 13 to the connecting shaft 10 by the second clutch 14. Furthermore, the first and second electrical machines 11, 13 are independently controllable from one another, ie also independently of one another in a motor or generator mode transferrable, as is optionally the case, the application thread 6 can assume any different operating states:
Erstens kann die erste Kupplung 12 die beiden elektrischen Maschinen 11, 13 von der Verbrennungskraftmaschine 7 lösen und die Verbrennungskraftmaschine 7 dabei beispielsweise stillge legt werden, sodass die beiden elektrischen Maschinen 11, 13 (oder optional nur eine davon) den Endantrieb 9 und somit das Fahrzeug antreiben. First, the first clutch 12 can release the two electrical machines 11, 13 from the internal combustion engine 7 and the internal combustion engine 7 can be shut down, for example, so that the two electrical machines 11, 13 (or optionally only one of them) drive the final drive 9 and thus the vehicle drive.
Zweitens kann die zweite Kupplung 14 die zweite elektri sche Maschine 13 von der Verbindungswelle 10 lösen, und die zweite elektrische Maschine 13 dabei alleine das Fahrzeug an treiben (oder bremsen); in diesem Fall können die Verbrennungs kraftmaschine 7 und die erste elektrische Maschine 11 stillge legt werden oder die Verbrennungskraftmaschine 7 treibt die ü- ber die erste Kupplung 12 verbundene erste elektrische Maschine 11, welche dabei im generatorischen Betrieb elektrische Energie für die zweite elektrische Maschine 13 erzeugt. Second, the second clutch 14 can release the second electrical machine 13 from the connecting shaft 10, and the second electrical machine 13 alone drive (or brake) the vehicle; In this case, the internal combustion engine 7 and the first electrical machine 11 can be shut down or the internal combustion engine 7 drives the first electrical machine 11 connected via the first clutch 12, which generates electrical energy for the second electrical machine 13 in generator mode .
Drittens können beide Kupplungen 12, 14 jeweils geschlos sen sein, sodass die Verbrennungskraftmaschine 7, die erste e- lektrische Maschine 11 und die zweite elektrische Maschine 13 miteinander mechanisch verbunden sind und entweder alle drei Maschinen 7, 11, 13 das Fahrzeug antreiben oder zumindest eine der elektrischen Maschinen 11, 13 dabei generatorisch betrieben wird und elektrische Energie erzeugt. Third, both clutches 12, 14 can each be closed so that the internal combustion engine 7, the first electrical machine 11 and the second electrical machine 13 are mechanically connected to one another and either all three machines 7, 11, 13 drive the vehicle or at least one of the electrical machines 11, 13 is operated as a generator and generates electrical energy.
Es versteht sich, dass die zweite Kupplung 14 an jeder be liebigen Stelle der Verbindungswelle 10 zwischen der ersten und der zweiten elektrischen Maschine 11, 13 angeordnet sein kann, um die genannten Betriebszustände zu erzielen. It goes without saying that the second clutch 14 can be arranged at any point on the connecting shaft 10 between the first and second electrical machines 11, 13 in order to achieve the aforementioned operating states.
Wie in den Fig. 3a - 3c dargestellt, ist die Verbindungs welle 10 mit Radialabstand R in einem Rohr 15 des Antriebs strangs 6 aufgenommen. Durch den Radialabstand R ist zwischen dem Rohr 15 und der Verbindungswelle 10 ein Ringraum 16 ausge bildet. Der Ringraum 16 ist optional in zwei oder mehrere Kam mern K , K2, ..., allgemein Ki, unterteilt. Eine solche Untertei- lung kann in Umfangsrichtung (wie gezeigt) oder alternativ bzw. zusätzlich in Achsrichtung des Rohrs 15 bestehen. As shown in FIGS. 3a - 3c, the connecting shaft 10 is received with a radial distance R in a tube 15 of the drive train 6. Due to the radial distance R, an annular space 16 is formed between the tube 15 and the connecting shaft 10. The annular space 16 is optionally divided into two or more chambers K, K 2 , ..., generally Ki. Such a sub- Treatment can exist in the circumferential direction (as shown) or alternatively or additionally in the axial direction of the tube 15.
Im Beispiel der Fig. 3a ist in den Ringraum 16 ein Kraft stoffbehälter 17 aufgenommen, welcher optional den Kammern Ki des Ringraums 16 entsprechend unterteilt ist. Im Beispiel der Fig. 3b ist in den Kammern Ki des Ringraums 16 ein - hier viel zelliger - elektrischer Energiespeicher 18 aufgenommen. Fig. 3c zeigt eine Variante, bei welcher in zwei Kammern Ki, K2 jeweils Zellen des elektrischen Energiespeichers 18, in einer dritten Kammer K3 Leistungselektronik 19 zur geregelten elektrischen Energieversorgung zumindest einer elektrischen Maschine 11, 13 und in einer vierten Kammer K4 eine Regelung 20 für die elekt rischen Maschinen 11, 13 bzw. für die Leistungselektronik 19 aufgenommen sind. So speist der elektrische Energiespeicher 18 - im Allgemeinen über die Leistungselektronik 19 - zumindest eine der (hier: beide) elektrischen Maschinen 11, 13 bzw. wird von diesen, wenn sie generatorisch betrieben werden, mit elekt rischer Energie gespeist, welche der Energiespeicher 18 in sei nen Zellen speichert. Es versteht sich, dass die in den Fig. 3a, 3b und 3c dargestellten Varianten der Nutzung des Ringraums 16 miteinander kombinierbar sind. In the example of Fig. 3a, a fuel tank 17 is added to the annular space 16, which is optionally divided into the chambers Ki of the annular space 16 accordingly. In the example of FIG. 3b, an electrical energy store 18 - here much cellular - is accommodated in the chambers Ki of the annular space 16. Fig. 3c shows a variant in which in two chambers Ki, K 2 cells of the electrical energy store 18, in a third chamber K 3 power electronics 19 for regulated electrical energy supply at least one electrical machine 11, 13 and in a fourth chamber K 4 one Control 20 for the electrical machines 11, 13 or for the power electronics 19 are added. The electrical energy store 18 feeds - generally via the power electronics 19 - at least one of the (here: both) electrical machines 11, 13 or, if they are operated as a generator, is fed with electrical energy which the energy store 18 in stores its cells. It goes without saying that the variants of the use of the annular space 16 shown in FIGS. 3a, 3b and 3c can be combined with one another.
Zurückkommend auf die Beispiele der Fig. 1 und 2 werden im Folgenden Varianten des Zentralrohrrahmens 2, welcher den ge zeigten Antriebsstrang 6 enthält, beschrieben. In jeder dieser Varianten des Zentralrohrrahmens 2 sind die Verbrennungskraft maschine 7 und das Rohr 15 des Antriebsstrangs 6 jeweils tra gende Elemente des Zentralrohrrahmens 2. Returning to the examples of FIGS. 1 and 2, variants of the central tubular frame 2, which contains the drive train 6 shown, are described below. In each of these variants of the central tubular frame 2, the internal combustion engine 7 and the tube 15 of the drive train 6 are each supporting elements of the central tubular frame 2.
Im einfachsten Fall ist der Zentralrohrrahmen 2 ohne weit- re tragende Elemente durch die Verbrennungskraftmaschine 7, z.B. ihren Motorblock 21, und das Rohr 15 gebildet, welches in diesem Fall direkt am Motorblock 21 verankert ist und in wel chem neben der Verbindungswelle 10 in diesem Fall auch die Kupplung 12, die elektrische Maschine 11 und der Endantrieb 9 aufgenommen sind. In den Ausführungsvarianten der Fig. 1 und 2 ist der Zent ralrohrrahmen 2 durch den Motorblock 21 der Verbrennungskraft maschine 7, ein an dem Motorblock 21 verankertes optionales erstes Gehäuse 22, das Rohr 15, welches in diesen Varianten an dem ersten Gehäuse 22 verankert ist, und ein an dem Rohr 15 verankertes optionales zweites Gehäuse 23 gebildet. Dabei ist ferner die (hier: erste) elektrische Maschine 11 auf die Ver bindungswelle 10 aufgesteckt und zusammen mit der (hier: ers ten) Kupplung 12 im ersten Gehäuse 22 aufgenommen. Im zweiten Gehäuse 23 sind die zweite elektrische Maschine 13 des An triebsstrangs 6, ein daran angeschlossenes Achsgetriebe 24 des Endantriebs 9 und die zweite Kupplung 14 aufgenommen. In the simplest case, the central tube frame 2 is formed by the internal combustion engine 7, for example its engine block 21, and the tube 15 without any further supporting elements, which in this case is anchored directly to the engine block 21 and in which case it is next to the connecting shaft 10 the clutch 12, the electric machine 11 and the final drive 9 are also included. In the embodiment variants of FIGS. 1 and 2, the central tube frame 2 is anchored to the engine block 21 by the engine block 21 of the internal combustion engine 7, an optional first housing 22, the tube 15, which in these variants is anchored to the first housing 22, and an optional second housing 23 anchored to tube 15 is formed. The (here: first) electrical machine 11 is also plugged onto the connecting shaft 10 and received in the first housing 22 together with the (here: first) coupling 12. In the second housing 23, the second electric machine 13 of the drivetrain 6, a connected axle gear 24 of the final drive 9 and the second clutch 14 are added.
In den Beispielen der Fig. 1 und 2 speist die zweite elektrische Maschine 13 das Achsgetriebe 24 über ein diesem vorgelagertes optionales Wechselgetriebe 25 des Endantriebs 9, z.B. ein automatisches, stufenloses, handgeschaltetes oder e- lektronisch geschaltetes Wechselgetriebe 25, an welches das Achsgetriebe 24 angeschlossen ist. Das Wechselgetriebe 25 kann dabei eine oder mehrere zusätzliche Kupplungen enthalten. In the examples of FIGS. 1 and 2, the second electrical machine 13 feeds the axle drive 24 via an optional change gear 25 of the final drive 9 upstream of it, for example an automatic, continuously variable, manually shifted or electronically switched change gear 25 to which the axle drive 24 is connected is. The change gear 25 can contain one or more additional clutches.
Es versteht sich, dass die erste Kupplung 12 und die erste elektrische Maschine 11, wenn der Antriebsstrang 6 keine zweite Kupplung 14 und keine zweite elektrische Maschine 13 umfasst, alternativ zu der dargestellten Variante im zweiten Gehäuse 23, oder die erste Kupplung 12 im ersten Gehäuse 22 und die erste elektrische Maschine 11 im zweiten Gehäuse 23 aufgenommen sein können. Ferner könnten alternativ die zweite Kupplung 14 im ersten Gehäuse 22, u.zw. abtriebsseitig, d.h. zwischen erster und zweiter elektrischer Maschine 11, 13, und die zweite elekt rische Maschine 13 im zweiten Gehäuse 23, oder überhaupt beide Kupplungen 12, 14 und elektrischen Maschinen 11, 13 jeweils im ersten oder zweiten Gehäuse 22, 23 aufgenommen sein. It goes without saying that the first clutch 12 and the first electrical machine 11, if the drive train 6 does not include a second clutch 14 and no second electrical machine 13, as an alternative to the variant shown in the second housing 23, or the first clutch 12 in the first housing 22 and the first electrical machine 11 can be accommodated in the second housing 23. Furthermore, the second clutch 14 in the first housing 22, u.zw. On the output side, i.e. between the first and second electrical machine 11, 13, and the second electrical machine 13 in the second housing 23, or both clutches 12, 14 and electrical machines 11, 13 in each case in the first or second housing 22, 23.
Das zweite Gehäuse ist optional zum Verankern des hinteren Fahrwerks 4 ausgebildet, welches die Räder 26 und jeweils eine Radaufhängung 27 für jedes Rad 26 umfasst. Zum Endantrieb 9 gehören hier neben dem Achsgetriebe 24 noch Antriebswellen 28, welche die Räder 26 treiben. The second housing is optionally designed for anchoring the rear undercarriage 4, which comprises the wheels 26 and a wheel suspension 27 for each wheel 26. To final drive 9 In addition to the axle drive 24, drive shafts 28 which drive the wheels 26 also belong here.
Im Beispiel der Fig. 2 ist der Motorblock 21 der Verbren nungskraftmaschine 7 optional an seiner dem Rohr 15 abgewandten Seite zum Verankern des vorderen Fahrwerks 3, insbesondere der Radaufhängung 29 für die Vorderräder 30, ausgebildet. Alterna tiv dazu treibt der Endantrieb 9 das vordere Fahrwerk 3 des Fahrzeugs, welches in diesem Fall optional am zweiten Gehäuse 23 verankert ist. In the example of FIG. 2, the engine block 21 of the internal combustion engine 7 is optionally designed on its side facing away from the pipe 15 for anchoring the front chassis 3, in particular the wheel suspension 29 for the front wheels 30. Alternatively, the final drive 9 drives the front chassis 3 of the vehicle, which in this case is optionally anchored on the second housing 23.
Im Beispiel der Fig. 1 hat der Zentralrohrrahmen 2 einen zweiarmigen Träger 31, an welchem das vordere Fahrwerk 3 des Fahrzeugs verankert ist. Jeder Trägerarm 31i, 31r des TrägersIn the example in FIG. 1, the central tubular frame 2 has a two-armed support 31 on which the front chassis 3 of the vehicle is anchored. Each support arm 31i, 31 r of the carrier
31 ist an jeweils einer Lateralseite des ersten Gehäuses 22 verankert. Ferner umgreifen die Trägerarme 31i, 31r den Motor block 21 der Verbrennungskraftmaschine 7 an seinen Lateralsei ten, d.h. jeder Trägerarm 31i, 31r wird - ohne direkten Kontakt - an jeweils einer Lateralseite des Motorblocks 21 vorbeige führt und überragt den Motorblock 21 an seiner dem Rohr 15 ab gewandten Seite in Axialrichtung des Zentralrohrahmens 2. 31 is anchored on each lateral side of the first housing 22. Furthermore, the support arms 31i, 31 r encompass the engine block 21 of the internal combustion engine 7 at its Lateralsei th, ie each support arm 31i, 31 r is - without direct contact - leads past one lateral side of the engine block 21 and protrudes beyond the engine block 21 at its Tube 15 from the opposite side in the axial direction of the central tubular frame 2.
In diesem Beispiel ist ferner an den Trägerarmen 31i, 31r ein optionales drittes Gehäuse 32 (hier: etwa mittig zwischen den Trägerarmen 31r, 31i) verankert. Das dritte Gehäuse 32 ist in der dargestellten Ausführungsform vom Motorblock 21 an sei ner dem Rohr 15 abgewandten Seite beabstandet, könnte jedoch alternativ oder zusätzlich an dieser Seite des Motorbocks 21 verankert sein. In dem dritten Gehäuse 32 sind eine dritte elektrische Maschine 33 und ein weiteres Achsgetriebe 34 aufge nommen, welches über vordere Antriebswellen 35 das vordere Fahrwerk 3 des Fahrzeugs, d.h. die Vorderräder 30, antreibt. In this example, further to the support arms 31i, 31 r an optional third housing 32 (here approximately centrally r between the carrier arms 31, 31i) anchored. In the embodiment shown, the third housing 32 is spaced from the engine block 21 on its side facing away from the pipe 15, but could alternatively or additionally be anchored on this side of the engine bracket 21. In the third housing 32, a third electrical machine 33 and a further axle drive 34 are taken up, which drives the front chassis 3 of the vehicle, ie the front wheels 30, via front drive shafts 35.
In Ausführungsform nach Fig. 2 entfällt der Träger 31. Stattdessen ist das dritte Gehäuse 32 an der dem Rohr 15 abge wandten Seite des Motorblocks 21 der Verbrennungskraftmaschinen 7 verankert. Auch in diesem Fall treibt die im dritten GehäuseIn the embodiment according to FIG. 2, the carrier 31 is omitted. Instead, the third housing 32 is anchored on the side of the engine block 21 of the internal combustion engine 7 facing away from the pipe 15. In this case, too, the one in the third housing drives
32 untergebrachte dritte elektrische Maschine 33 über das weite Achsgetriebe 34 das vordere Fahrwerk 3 des Fahrzeugs. Die vor- dere Radaufhängung 29 ist in diesem Beispiel am dritten Gehäuse 32 verankert. 32 housed third electrical machine 33 via the wide axle drive 34 the front chassis 3 of the vehicle. The previous Their wheel suspension 29 is anchored on the third housing 32 in this example.
Optional wird die dritte elektrische Maschine 33 - wie die erste und die zweite elektrische Maschine 11, 13 - im Motorbe trieb aus dem elektrischen Energiespeicher 18 gespeist bzw. speist im Generatorbetrieb den elektrischen Energiespeicher 18, z.B. jeweils über die Leistungselektronik 19. Im Allgemeinen wird die dritte elektrische Maschine 33 unabhängig von den bei den anderen elektrischen Maschinen 11, 13, d.h. auch über eine separate Leistungselektronik 19 gespeist. Es versteht sich, dass die dritte elektrische Maschine 33 auch in der Ausfüh rungsform des Antriebsstrangs 6 ohne zweite elektrische Maschi ne 13 eingesetzt werden kann. Optionally, the third electrical machine 33 - like the first and second electrical machines 11, 13 - is powered from the electrical energy store 18 in motor mode or, in generator mode, feeds the electrical energy store 18, for example via the power electronics 19. In general, the third electrical machine 33 independently of the other electrical machines 11, 13, that is to say also fed via separate power electronics 19. It goes without saying that the third electrical machine 33 can also be used in the embodiment of the drive train 6 without a second electrical machine 13.
In der alternativen Ausführungsform, in welchen der An triebsstrang 6 das vordere Fahrwerk 3 treibt, treibt umgekehrt die dritte elektrische Maschine 33 das hintere Fahrwerk 4. In the alternative embodiment, in which the drive train 6 drives the front landing gear 3, the third electrical machine 33, conversely, drives the rear landing gear 4.
Ein optionaler Aufprallschutz 36 mit einem Stoßfänger 37 ist beispielsweise an den Trägerarmen 31i, 31r (Fig. 1) oder an dem dritten Gehäuse 32 (Fig. 2) verankert. An optional impact protection 36 with a bumper 37 is, for example, on the carrier arms 31i, 31 r (Fig. 1) or to the third housing 32 (Fig. 2) anchored.
Fig. 4 zeigt das Fahrgestell 1 einer landwirtschaftlichen Zugmaschine, z.B. eines Traktors, welches mit dem Zentralrohr rahmen 2 und dem Antriebsstrang 6 gemäß der Ausführungsform von Fig. 2 ausgestattet ist. Es versteht sich, dass das Fahrgestell 1 der landwirtschaftlichen Zugmaschine alternativ mit einer an deren der beschriebenen Varianten des Zentralrohrrahmens 2 bzw. des Antriebsstrangs 6, z.B. jener mit einem Träger 31 ausges tatteten Variante gemäß Fig. 1 oder einer Variante mit nur zwei oder nur der einen (ersten) elektrischen Maschine 11 gebildet sein kann. FIG. 4 shows the chassis 1 of an agricultural tractor, for example a tractor, which is equipped with the central tubular frame 2 and the drive train 6 according to the embodiment of FIG. It goes without saying that the chassis 1 of the agricultural tractor can alternatively be equipped with one of the described variants of the central tubular frame 2 or the drive train 6, for example that variant according to FIG. 1 equipped with a carrier 31 or a variant with only two or only the a (first) electrical machine 11 can be formed.
In Fig. 5 ist eine den Zentralrohrrahmen 2 umfassende Va riante des Fahrgestells 1 eines Lastkraftwagens gezeigt. Das Fahrgestell 1 ist in diesem Beispiel dreiachsig; das hintere Fahrwerk 4 und das zweite Gehäuse 23 mit darin aufgenommener zweiter Kupplung 14, zweiter elektrischer Maschine 13, optiona lem Wechselgetriebe 25 und Achsgetriebe 24 ist gleichsam ver- doppelt als viertes Gehäuse 38, an welchem ein zweites hinteres Fahrwerk 39 verankert ist, das die dritte Fahrzeugachse bildet. Das zweite hintere Fahrwerk 39 ist optional ebenfalls angetrie ben, z.B. über einen aus dem zweiten Gehäuse 23 herausgeführten Wellstummel 40, welcher über ein zweites hinteres Achsgetriebe 41 das zweite hintere Fahrwerk 39 antreibt. In Fig. 5, the central tube frame 2 comprehensive Va riante of the chassis 1 of a truck is shown. The chassis 1 is triaxial in this example; the rear undercarriage 4 and the second housing 23 with the second clutch 14, the second electric machine 13, the optional change gear 25 and the axle gear 24 accommodated therein doubly as a fourth housing 38, on which a second rear chassis 39 is anchored, which forms the third vehicle axle. The second rear chassis 39 is optionally also driven, for example via a shaft stub 40 which is led out of the second housing 23 and which drives the second rear chassis 39 via a second rear axle drive 41.
Im Beispiel der Fig. 5 sind in dem vierten Gehäuse 38 fer ner eine optionale vierte elektrische Maschine 42 und ein an das zweite hintere Achsgetriebe 41 angeschlossenes optionales zweites Wechselgetriebe 43 aufgenommen; dabei ist optional der Wellenstummel 40 direkt mit der zweiten elektrischen Maschine 13 verbunden. Die vierte elektrische Maschine 42 ist in diesem Beispiel über eine dritte Kupplung 44 mit den Wellenstummel 40 lösbar verbunden und treibt das zweite Wechselgetriebe 43; al ternativ entfallen der Wellenstummel 40 und die dritte Kupplung 44, sodass die vierte elektrische Maschine 42 - ähnlich der dritten elektrischen Maschine 33 am vorderen Fahrwerk 3 - unab hängig vom Antriebsstrang 6 das zweite hintere Fahrwerk 39 treibt. Auch die vierte elektrische Maschine 42 speist optional den elektrischen Energiespeicher 18 bzw. wird von diesem ge speist, z.B. jeweils über Leistungselektronik 19. In the example of FIG. 5, an optional fourth electric machine 42 and an optional second change gear 43 connected to the second rear axle gear 41 are included in the fourth housing 38; The shaft stub 40 is optionally connected directly to the second electrical machine 13. In this example, the fourth electrical machine 42 is detachably connected to the shaft stub 40 via a third clutch 44 and drives the second change gear 43; Alternatively, the stub shaft 40 and the third clutch 44 are omitted, so that the fourth electric machine 42 - similar to the third electric machine 33 on the front chassis 3 - drives the second rear chassis 39 independently of the drive train 6. The fourth electrical machine 42 also optionally feeds the electrical energy store 18 or is fed by it, e.g. via power electronics 19 in each case.
Fig. 6 zeigt ein Beispiel, in welchem der Endantrieb 9 ei ne Antriebsachse 45 und einen von dieser angetriebenen Propel ler 46 für ein durch einen Bootsrumpf 47 versinnbildlichtes Wasserfahrzeug umfasst. Die Funktion und das Zusammenwirken der Verbrennungskraftmaschine 7 mit zumindest einer elektrischen Maschine 11, 13 entspricht weitgehend jenen zuvor für Landfahr zeuge beschriebenen Varianten, wie dem Fachmann unmittelbar er sichtlich ist. Ferner kann der Zentralrohrrahmen 2 als tragen des bzw. verstärkendes Element für das Wasserfahrzeug genutzt werden. 6 shows an example in which the final drive 9 comprises a drive axle 45 and a propeller 46 driven by this for a watercraft symbolized by a boat hull 47. The function and the interaction of the internal combustion engine 7 with at least one electrical machine 11, 13 largely corresponds to the variants previously described for land vehicles, as it is immediately apparent to the person skilled in the art. Furthermore, the central tube frame 2 can be used as a support or reinforcing element for the watercraft.
