Description
Die Erfindung betrifft eine Hybrid-Antriebsvorrichtung mit einem Verbrennungsmotor, einer elektrischen Maschine und einem Getriebe nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a hybrid drive device with an internal combustion engine, an electric machine and a transmission according to the type defined in more detail in the preamble of
Zum Stand der Technik beschreibt beispielsweise die
Trotz vergleichsweise wenigen Gangstufen ist der Aufbau dabei relativ groß, vor allem auch in axialer Richtung, also in der entlang der Eingangswelle des Getriebes verlaufenden Richtung.Despite comparatively few gears, the structure is relatively large, especially in the axial direction, ie in the direction running along the input shaft of the transmission.
Die Aufgabe der hier vorliegenden Erfindung besteht nun darin, eine verbesserte Hybrid-Antriebsvorrichtung anzugeben, welche trotz einer Vielzahl von Gangstufen vor allem in axialer Richtung sehr kompakt baut, und welche darüber hinaus in der Lage ist, im Hybrid-Modus ohne vollständige Zugkraftunterbrechung zu schalten.The object of the present invention is to specify an improved hybrid drive device which, despite a large number of gears, is very compact, especially in the axial direction, and which is also able to switch gears in hybrid mode without a complete interruption in traction .
Erfindungsgemäß wird diese Aufgabe durch eine Hybrid-Antriebsvorrichtung mit den Merkmalen im Anspruch 1, und hier insbesondere im kennzeichnenden Teil des Anspruchs 1, gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Hybrid-Antriebsvorrichtung ergeben sich aus den hiervon abhängigen Unteransprüchen.According to the invention, this object is achieved by a hybrid drive device having the features in
Die Hybrid-Antriebsvorrichtung gemäß der Erfindung umfasst also neben dem Verbrennungsmotor eine elektrische Maschine sowie ein Getriebe. Das Getriebe umfasst eine Eingangswelle und wenigstens eine Vorgelegewelle. Dabei sind mindestens sechs schaltbare Radpaarungen mit jeweils einem koaxial zu der Eingangswelle angeordneten Zahnrad vorgesehen, wobei eine erste der Radpaarungen zwei Losräder umfasst, eines auf der Eingangswelle und eines auf der wenigstens einen Vorgelegewelle. Die elektrische Maschine ist derart an diese erste Radpaarung angebunden, dass Drehmomente ausgehend von der elektrischen Maschine über die erste Radpaarung in das Getriebe eingeleitet werden können. Durch die Ausgestaltung der ersten Radpaarung über zwei Losräder ist dabei sowohl eine P2-Anbindung als auch eine P3-Anbidnung möglich. Die erste Radpaarung ist dabei entlang der Eingangswelle von der Trennkupplung aus gesehen die letzte oder vorletzte Radpaarung. Erfindungsgemäß ist es so, dass die elektrische Maschine in axialer Richtung die Trennkupplung überlappt. Die überlappende Anordnung im Sinne der Erfindung bedeutet dabei, dass die genannten Elemente in derselben axialen Ebene liegen können oder aber vorzugsweise in axialer Richtung in dieselbe axiale Ebene hineinragen. Die axiale Ebene ist dabei jeweils auf die Eingangswelle bezogen, so dass jede axiale Ebene senkrecht auf einer Drehachse der Eingangswelle und damit auf der axialen Richtung steht.The hybrid drive device according to the invention thus includes, in addition to the internal combustion engine, an electric machine and a transmission. The transmission includes an input shaft and at least one countershaft. At least six shiftable wheel pairs are provided, each with a gear wheel arranged coaxially to the input shaft, with a first of the wheel pairs comprising two loose wheels, one on the input shaft and one on the at least one countershaft. The electrical machine is connected to this first pair of wheels in such a way that torques can be introduced into the transmission from the electrical machine via the first pair of wheels. Due to the configuration of the first pair of wheels via two loose wheels, both a P2 connection and a P3 connection are possible. The first pair of wheels is the last or penultimate pair of wheels along the input shaft as seen from the separating clutch. According to the invention, the electrical machine overlaps the separating clutch in the axial direction. The overlapping arrangement within the meaning of the invention means that the elements mentioned can lie in the same axial plane or preferably protrude in the axial direction into the same axial plane. The axial plane is in each case related to the input shaft, so that each axial plane is perpendicular to an axis of rotation of the input shaft and thus to the axial direction.
Die axiale Richtung ist dabei identisch mit einer Richtung der Drehachse der Eingangswelle.The axial direction is identical to a direction of the axis of rotation of the input shaft.
Mit einem auf einer Welle angeordneten Losrad ist ein koaxial und drehbar zu dieser Welle angeordnetes Zahnrad gemeint, das mittels einer zugehörigen Schalteinrichtung drehfest mit der genannten Welle verbunden werden kann. Die zugehörige Schalteinrichtung ist dabei ebenfalls koaxial zu der genannten Welle angeordnet.A loose wheel arranged on a shaft means a gear wheel which is arranged coaxially and rotatably with respect to this shaft and which can be connected in a rotationally fixed manner to the said shaft by means of an associated switching device. The associated switching device is also arranged coaxially to said shaft.
Mit einem Festrad ist dagegen ein Zahnrad gemeint, das koaxial zu einer Welle angeordnet ist und permanent drehfest mit dieser Welle verbunden ist.A fixed wheel, on the other hand, means a gear wheel which is arranged coaxially to a shaft and is permanently connected to this shaft in a rotationally fixed manner.
Mit einer drehfesten Verbindung zweier drehbar gelagerter Elemente ist generell gemeint, dass die beiden Elemente koaxial zueinander angeordnet sind und derart miteinander verbunden sind, dass sie mit gleicher Winkelgeschwindigkeit drehen.A non-rotatable connection of two rotatably mounted elements generally means that the two elements are arranged coaxially to one another and are connected to one another in such a way that they rotate at the same angular velocity.
Unter einer Radpaarung sollen genau zwei miteinander kämmende Zahnräder verstanden werden. Die beiden Zahnräder sind dabei im Wesentlichen in einer gemeinsamen axialen Ebene angeordnet.A pair of wheels should be understood to mean exactly two gears meshing with one another. The two gears are essentially arranged in a common axial plane.
Darunter, dass ein erstes Element axial überlappend zu einem zweiten Element angeordnet ist, ist zu verstehen, dass zumindest ein erster Teil des ersten Elementes und ein zweiter Teil des zweiten Elementes einen gleichen axialen Erstreckungsbereich haben.The fact that a first element is arranged in an axially overlapping manner with respect to a second element means that at least a first part of the first element and a second part of the second element have the same axial extent.
Unter einer koaxialen Anordnung eines Elementes in Bezug auf ein anderes Element ist gemeint dass eine Drehachse des Elementes und eine andere Drehachse des anderen Elementes identisch sind.By a coaxial arrangement of one element with respect to another element is meant that an axis of rotation of the element and a other axis of rotation of the other element are identical.
Auf die oben genannte Weise wird ein außerordentlich kompakter Aufbau der erfindungsgemäßen Hybrid-Antriebsvorrichtung sichergestellt, welche eine dementsprechend kompakte Bauweise bei durch die spezielle Radsatzarchitektur erreichten sehr geringen Kosten ermöglicht. Außerdem ist trotz des einfachen Aufbaus die volle Funktionalität von sechs oder mehr Gangstufen und ein hoher Komfort bei den Schaltungen gegeben.In the manner mentioned above, an extraordinarily compact construction of the hybrid drive device according to the invention is ensured, which enables a correspondingly compact construction at very low costs achieved by the special wheelset architecture. In addition, despite the simple structure, the full functionality of six or more gears and a high level of comfort in the circuits is given.
Die Hybrid-Antriebsvorrichtung gemäß der Erfindung kann dazu vorzugsweise auf eine anfahrfähige Trennkupplung sowie insbesondere auch auf einen mechanischen Rückwärtsgang verzichten. Hierdurch lässt sich der Durchmesser der Trennkupplung entsprechend gering auslegen, sodass diese platzsparend überlappend zu der elektrischen Maschine und gemäß einer außerordentlich günstigen Weiterbildung hierzu überlappend zu wenigstens einem Abtriebsrad auf der wenigstens einen Vorgelegewelle angeordnet sein kann.For this purpose, the hybrid drive device according to the invention can preferably dispense with a separating clutch capable of starting off and, in particular, also with a mechanical reverse gear. As a result, the diameter of the separating clutch can be designed to be correspondingly small, so that it can be arranged to save space, overlapping the electric machine and, according to an extremely favorable development, overlapping at least one output gear on the at least one countershaft.
Für eine besonders günstige Weiterbildung mit zwei Vorgelegewellen, welche jeweils ein Abtriebsrad aufweisen, können insbesondere die Trennkupplung und die beiden Abtriebsräder axial überlappend angeordnet sein. Dieser Aufbau mit einer bezüglich ihres Durchmessers sehr kleinen Trennkupplung kann insbesondere durch den Verzicht auf die Anfahrfähigkeit der Trennkupplung erreicht werden.For a particularly favorable further development with two countershafts, each of which has a driven gear, the separating clutch and the two driven gears can in particular be arranged in an axially overlapping manner. This design with a very small separating clutch in terms of its diameter can be achieved in particular by dispensing with the ability of the separating clutch to start up.
In einem Hybrid-Fahrzeug mit der erfindungsgemäßen Hybrid-Antriebsvorrichtung ist es dann möglich, dass diese zusammen mit einer weiteren rein elektrisch angetriebenen Achse zum Antrieb einer über die Hybrid-Antriebsvorrichtung angetriebenen Achse eingesetzt wird. Anfahrvorgänge sowie eine Rückwärtsfahrt können dann rein elektrisch mit einer oder auch beiden elektrischen Maschinen, also der der erfindungsgemäßen Hybrid-Antriebsvorrichtung und der der weiteren rein elektrisch angetriebenen Achse realisiert werden. Die Schaltungen innerhalb des Getriebes können für den Fall des Hybrid-Antriebs mit dem Verbrennungsmotor unf ggf. der elektrischen Maschine ohne Lastunterbrechung erfolgen, indem die elektrische Maschine in der P3-Anbindung während der Schaltung die Drehzahlen und Drehmomente entsprechend ausgleicht bzw. stützt.In a hybrid vehicle with the hybrid drive device according to the invention, it is then possible for this to be used together with another purely electrically driven axle to drive an axle driven via the hybrid drive device. Starting processes and reversing can then be implemented purely electrically with one or both electrical machines, ie the hybrid drive device according to the invention and the other purely electrically driven axle. In the case of the hybrid drive with the internal combustion engine and, if necessary, the electric machine, the shifts within the transmission can take place without load interruption, in that the electric machine in the P3 connection compensates for or supports the speeds and torques accordingly during the shift.
Gemäß einer weiteren sehr günstigen Ausgestaltung der erfindungsgemäßen Hybrid-Antriebsvorrichtung in der oben beschriebenen vorteilhaften Ausgestaltung mit zwei Vorgelegewellen sieht es dabei vor, dass zumindest zwei Doppelradebenen vorgesehen sind, was den Aufbau der Radsätze vereinfacht und in axialer Richtung eine sehr kompakte Bauweise des Getriebes erlaubt.According to a further very favorable embodiment of the hybrid drive device according to the invention in the advantageous embodiment described above with two countershafts, at least two double wheel planes are provided, which simplifies the structure of the wheel sets and allows a very compact design of the transmission in the axial direction.
Mit dem Begriff der Doppelradebene sind zwei in einer axialen Ebene liegende Radpaarungen gemeint, wobei die beiden Radpaarungen ein gemeinsames Zahnrad haben. Das gemeinsame Zahnrad ist dabei koaxial zu der Drehachse der Eingangswelle angeordnet und kämmt sowohl mit einem Rad der einen Radpaarung als auch mit einem anderen Rad der anderen Radpaarung.The term double wheel plane means two wheel pairs lying in an axial plane, with the two wheel pairs having a common gear wheel. The common gear wheel is arranged coaxially to the axis of rotation of the input shaft and meshes both with a wheel of one pair of wheels and with another wheel of the other pair of wheels.
Von den zwei vorgesehenen Doppelradebenen wird eine von zwei der 6 schaltbaren Radpaarungen gebildet. Die andere wird von zwei anderen der 6 schaltbaren Radpaarungen gebildet. Somit sind gemäß dieser Weiterbildung 4 der schaltbaren Radpaarungen in lediglich 2 axialen Ebenen angeordnet.One of two of the 6 switchable wheel pairs is formed by the two planned double wheel planes. The other is formed by two other of the 6 switchable wheel pairs. Thus, according to this development, 4 of the shiftable wheel pairs are arranged in only 2 axial planes.
Die elektrische Maschine kann dabei direkt über ein mit ihrer Rotorwelle drehfest verbundenes, also mit der gleichen Drehzahl umlaufendes, Ritzel angebunden werden oder über ein entsprechendes Getriebeelement, welches prinzipiell jede Art von Getriebeelemente wie beispielsweise, ein Zwischenrad, ein Zwischengetriebe, ein Kettenantrieb oder dergleichen sein kann, an die erste Radpaarung angebunden sein. Die Anbindung kann dabei entweder im zweiten Zahnrad der erste Radpaarung oder alternativ dazu auch am ersten Zahnrad der Radpaarung, also entweder an dem koaxial zur Vorgelegewelle oder an dem koaxial zur Eingangswelle des Getriebes angeordneten Zahnrad der ersten Radpaarung erfolgen. Hierdurch ist eine weitere Optimierung hinsichtlich des zur Verfügung stehenden Bauraums möglich. Durch die Ausgestaltung der beiden Zahnräder der ersten Radpaarung als Losräder ermöglichen dabei beide Varianten sowohl eine P2- als auch eine P3-Anbindung.The electric machine can be connected directly via a pinion that is non-rotatably connected to its rotor shaft, i.e. rotating at the same speed, or via a corresponding transmission element, which in principle can be any type of transmission element such as an intermediate wheel, an intermediate gear, a chain drive or the like can be connected to the first pair of wheels. The connection can be made either in the second gear of the first pair of wheels or alternatively also on the first gear of the pair of wheels, ie either on the coaxial to the countershaft or on the gear of the first pair of wheels arranged coaxially to the input shaft of the transmission. As a result, further optimization with regard to the available installation space is possible. By configuring the two gear wheels of the first pair of wheels as loose wheels, both variants allow both a P2 and a P3 connection.
Vorzugsweise kann die elektrische Maschine dabei an der in axialer Richtung von der Trennkupplung aus gesehen letzten Radpaarung angebunden sein, sodass diese sich in axialer Richtung entlang des sehr kompakten Aufbaus des Getriebes erstreckt und in der eingangs geschilderten Art und Weise überlappend zu der Trennkupplung und gemäß den beschriebenen Ausgestaltungen vorzugsweise auch in axialer Richtung überlappend zu dem wenigstens einen Abtriebsrad angeordnet sein.Preferably, the electric machine can be connected to the last wheel pair viewed in the axial direction from the separating clutch, so that it extends in the axial direction along the very compact structure of the transmission and overlaps the separating clutch in the manner described above and according to the described configurations preferably also be arranged overlapping in the axial direction to the at least one output gear.
Gemäß einer weiteren sehr günstigen Ausgestaltung können dabei genau sechs schaltbare Radpaarungen mit einem koaxial zur Eingangswelle angeordneten Zahnrad vorgesehen sein. Ein solches Getriebe erlaubt in einem sehr einfachen Aufbau, insbesondere bei dem oben beschriebenen Verzicht auf den mechanischen Rückwärtsgang, mit den sechs Radpaarungen die Realisierung von sechs Gangstufen. Dabei lassen sich die genau sechs Radpaarungen bei der Ausgestaltung mit zwei Vorgelegewellen beispielsweise auf drei Doppelradebenen oder auf zwei Doppelradebenen sowie zwei Einzelradebenen verteilen, um so die einzelnen Radebenen und benötigte Schaltkupplungen bezüglich ihrer Anordnung in axialer Richtung optimal und mit der gewünschten kurzen Bauform des Getriebes in Axialrichtung realisieren zu können.According to a further very favorable embodiment, exactly six switchable gear pairs can be provided with a gear wheel arranged coaxially to the input shaft. In a very simple design, such a transmission allows six gear stages to be realized with the six wheel pairs, in particular when the mechanical reverse gear is dispensed with as described above. The exactly six wheel In the design with two countershafts, the pairings can be distributed, for example, over three double wheel planes or two double wheel planes and two single wheel planes, in order to be able to optimally implement the individual wheel planes and required clutches with regard to their arrangement in the axial direction and with the desired short design of the transmission in the axial direction.
Bei der Ausführungsvariante mit zwei Vorgelegewellen kann es ferner vorgesehen sein, dass koaxial zu jeder der Vorgelegewellen wenigstens zwei schaltbare Losräder angeordnet sind, vorzugsweise jeweils axial benachbart zueinander. Durch diesen Aufbau kann der Aktuator für die Schaltung zwischen die beiden zueinander benachbarten Losräder verlagert werden, was den Aufbau nochmals einfacher und hinsichtlich der Ansteuerung und Aktuatorik kompakter macht.In the embodiment variant with two countershafts, it can also be provided that at least two switchable loose wheels are arranged coaxially with each of the countershafts, preferably in each case axially adjacent to one another. With this structure, the actuator for the shift can be shifted between the two mutually adjacent loose wheels, which makes the structure even simpler and more compact in terms of control and actuators.
Eine weitere sehr günstige Ausgestaltung der erfindungsgemäßen Hybrid-Antriebsvorrichtung kann es ferner vorsehen, dass in axialer Richtung auf die Trennkupplung folgend wenigstens zwei Festräder auf der Eingangswelle angeordnet sind, welche entsprechende Radpaarungen, vorzugsweise jeweils in einer Doppelradebene, ausbilden. Dieser Aufbau ist außerordentlich kompakt und effizient und kann insbesondere mit der oben genannten Kombination zur Anbindung der elektrischen Maschine an die letzte oder vorletzte Radpaarung als erste Radpaarung im Sinne der Erfindung die Kompaktheit des Aufbaus weiter unterstützten.Another very favorable embodiment of the hybrid drive device according to the invention can also provide that at least two fixed wheels are arranged on the input shaft following the separating clutch in the axial direction, which form corresponding wheel pairs, preferably each in a double wheel plane. This structure is extremely compact and efficient and can further support the compactness of the structure in the context of the invention, in particular with the above-mentioned combination for connecting the electric machine to the last or penultimate pair of wheels as the first pair of wheels.

In den nachfolgenden Figuren ist schematisch jeweils eine Hybrid-Antriebsvorrichtung 1 in einem erfindungsgemäßen Aufbau dargestellt. Die Radsatzpläne, welche zur Darstellung des darin verbauten Getriebes dienen, sind dabei weder maßstäblich zu verstehen noch liegen alle Bauteile zwingend in der Blattebene, in der sie dargestellt sind. Auch die Größenordnungen der Komponenten zueinander müssen dabei nicht dem realen Aufbau entsprechen.In the following figures, a
In axialer Richtung a der Eingangswelle 5 folgt von der Trennkupplung 4 aus gesehen koaxial zur Eingangswelle 5 ein erstes Festrad 7, ein zweites Festrad 8, ein erstes Losrad 9 sowie ein zweites Losrad 10 sowie zwischen diesen beiden Losrädern 9, 10 eine Schalteinrichtung 11, mit denen die Losräder 9, 10 jeweils drehfest mit der Eingangswelle 5 verbunden werden können. Drehfest im Sinne der Erfindung bedeutet dabei, dass die Elemente mit der gleichen Drehzahl umlaufen.In the axial direction a of the
Jeweils parallel zu der Eingangswelle 5 sind zwei Vorgelegewellen 12, 13 angeordnet. Beide Vorgelegewellen 12, 13 weisen in einer axialen Ebene mit der Trennkupplung 4 Abtriebsräder 14, 15 auf, welche ihrerseits beispielsweise mit einem hier nicht dargestellten Differential direkt oder über wenigstens ein zwischengeordnetes Getriebeelement kämmen.Two
Das zweite Losrad 10, welches in axialer Richtung a aus Blickrichtung der Trennkupplung 4 entlang der Eingangswelle 5 das letzte Zahnrad darstellt, bildet mit einem Losrad 16 der ersten Vorgelegewelle 12 eine erste Radpaarung 17 aus. Das erste Losrad 9 auf bzw. koaxial zur Eingangswelle 5 bildet mit einem Festrad 18 eine zweite Radpaarung 19 aus. Das in axialer Richtung a in Blickrichtung von der Trennkupplung aus vor diesem ersten Losrad 9 der zweiten Radpaarung 19 angeordnete zweite Festrad 8 bildet mit einem Losrad 20 auf der ersten Vorgelegewelle eine dritte Radpaarung 21 aus und mit einem weiteren Losrad 22, dieses mal auf der anderen der Vorgelegewelle 13, eine vierte Radpaarung 23. Vergleichbares gilt für das erste Festrad 7 der Eingangswelle 5, welches mit einem Losrad 24 auf der ersten Vorgelegewelle 12 eine fünfte Radpaarung 25 und mit einem Losrad 26 auf der zweiten Vorgelegewelle 13 eine sechste Radpaarung 27 ausbildet.The second
Eine Schalteinrichtung 28 für das Losrad 16 der ersten Radpaarung 17, also für das zweite Zahnrad der Radpaarung 17, ist zwischen der Radebene der ersten Radpaarung 17 und der Radebene der zweiten Radpaarung 19 in axialer Richtung a gesehen angeordnet. Vorzugsweise liegt die Schalteinrichtung 28 dabei in axialer Richtung a in einer axialen Ebene mit der Schalteinrichtung 11, welche als Doppelschalteinrichtung zwischen den beiden Losrädern 9, 10 auf der Eingangswelle 5 ausgebildet ist. Eine axiale Ebene bezeichnet dabei eine senkrecht zur axialen Richtung a beziehungsweise zur Eingangswelle 5 liegende Ebene.A switching
Zwischen den beiden als Doppelradebenen ausgebildeten axialen Radebenen mit der dritten und der vierten Radpaarung 21, 23 bzw. der fünften und der sechsten Radpaarung 25, 27 befinden sich zwei weitere Doppelschalteinrichtungen 29, 30, welche vorzugsweise wieder in einer axialen Ebene liegen. In derselben axialen Ebene wie die Trennkupplung 4 liegen außerdem, wie bereits erwähnt, die beiden Abtriebsräder 14, 15 der jeweiligen Vorgelegewellen 12, 13.Between the two axial gear planes configured as double gear planes with the third and fourth pair of
Die Anbindung der elektrischen Maschine 3 erfolgt nun so, dass ein Ritzel 31, welches drehfest mit einer Rotorwelle 32 der elektrischen Maschine verbunden ist, über ein optionales Zwischenrad 33 so an die erste Radpaarung 17 angebunden ist, dass Drehmoment von der elektrischen Maschine 3 in das Getriebe eingeleitet werden kann. Je nach Stellung der Schalteinrichtungen 11, 28 lässt sich dabei eine sogenannte P2-Anbindung realisieren, bei welcher die elektrische Maschine 3 über das Ritzel 31, das Zwischenrad 33, das lose auf der ersten Vorgelegewelle 12 umlaufende Losrad 16 der ersten Radpaarung und das mit der Eingangswelle über die Schalteinrichtung 11 gekoppelten Losrad 10 auf die Eingangswelle 5, und zwar auf der dem Verbrennungsmotor 2 abgewandten Seite der Trennkupplung 4, entsprechend wirkt. Je nach Schaltstellung innerhalb des Getriebes erfolgt dann der Abtrieb über die erste Vorgelegewelle12 und deren Abtriebsrad 14 oder die zweite Vorgelegewelle 13 und deren Abtriebsrad 15. Alternativ dazu wird der Aufbau zu einer sogenannten P3-Anbindung umgeschaltet, in dem bei geöffneter Schalteinrichtung 11 und dementsprechend auf der Eingangswelle 5 umlaufendem Losrad 10 und mit der ersten Vorgelegewelle 12 über die Schalteinrichtung 28 gekoppeltem Losrad 16 der ersten Radpaarung 17 die erste Vorgelegewelle 12 und damit ihr Abtriebsrad 14 von der elektrischen Maschine 3 angetrieben wird.The
Das Getriebe der Hybrid-Antriebsvorrichtung 1 kann beispielsweise so ausgestaltet sein, dass es als Sechsganggetriebe ohne mechanischen Rückwärtsgang genutzt wird. Dabei kann über die erste Radpaarung 17 die erste Gangstufe realisiert werden und über die zweite Radpaarung 19 die zweite Gangstufe. Über die fünfte Radpaarung 25 lässt sich dann die dritte Gangstufe und über die dritte Radpaarung 21 die vierte Gangstufe realisieren. Bei all diesen Gangstufen 1 bis 4 erfolgt der Abtrieb entsprechend über die erste Vorgelegewelle 12 und ihr Abtriebsrad 14, welches als Festrad drehfest mit der ersten Vorgelegewelle 12 verbunden ist. Über die beiden weiteren Radpaarungen der beiden Doppelradebenen um die Festräder 7, 8 auf der Eingangswelle 5 lassen sich dann die fünfte und die sechste Gangstufe realisieren, beispielsweise indem über die sechste Radpaarung 27 die fünfte Gangstufe und die vierte Radpaarung 23 die sechste Gangstufe geschaltet wird.The transmission of the
