In the following special driving modes are highlighted, which can be realized by means of the transmission shown in FIG. 1:
So ist mit der in der Figur 1 gezeigten Getriebestruktur ein Standladen der Elektromaschine 1 1 ermöglicht, sofern das Fahrzeug im Fahrzeugstillstand ist, zum Beispiel an einer Ampel oder im Stau. In diesem Fall kann Thus, with the transmission structure shown in Figure 1, a stand shop of the electric machine 1 1 allows, if the vehicle is in vehicle standstill, for example at a traffic light or in a traffic jam. In this case can
beispielhaft das Schaltelement SE-F nach rechts betätigt werden, um die Brennkraftmaschinen-Welle 3 mit der ersten Hybrid-Radebene E1 zu verbinden. Zugleich wird die Kupplung K1 (bestehend aus dem For example, the switching element SE-F are operated to the right to connect the engine shaft 3 with the first hybrid gear plane E1. At the same time, the clutch K1 (consisting of the
Außenlamellenträger 45 und dem Innenlamellenträger 49) geschlossen, um die erste Hybrid-Radebene E1 mit der Elektromaschinen-Welle 9 zu verbinden. Dadurch kann ein Momentenfluss von der Brennkraftmaschine 7 über die Brennkraftmaschinen-Welle 3, die erste Hybrid-Radebene E1 , die geschlossene Kupplung K1 bis zur Elektromaschine 1 1 erfolgen. Zudem ist mit Hilfe der Elektromaschine 1 1 ein Brennkraftmaschinen-Start durchführbar. Die Elektromaschine 1 1 kann die Brenn kraftmasch ine 7 über einen Lastpfad starten, bei dem beispielhaft die zweite Kupplung K2 Outer disk carrier 45 and inner disk carrier 49) are closed to connect the first hybrid gear plane E1 to the electric machine shaft 9. As a result, a torque flow from the internal combustion engine 7 via the engine shaft 3, the first hybrid wheel plane E1, the closed clutch K1 to the electric machine 11 take place. In addition, with the aid of the electric machine 1 1 an engine start-up feasible. The electric machine 1 1, the internal combustion engine ine 7 start via a load path, in the example, the second clutch K2
(bestehend aus dem Außenlamellenträger 45 und dem Innenlamellentrager 47) geschlossen ist und das Schaltelement SE-F nach links betätigt ist. (consisting of the outer disc carrier 45 and the inner disc carrier 47) is closed and the switching element SE-F is actuated to the left.
Ferner kann in der Figur 1 ein Schaltvorgang zwischen den Furthermore, in the figure 1, a switching operation between the
verbrennungsmotorischen Gängen 1 bis 6 mit Hilfe der Elektromaschine 1 1 zugkraftunterbrechungsfrei erfolgen, und zwar z.B. mit Hilfe der internal combustion engine gears 1 to 6 with the aid of the electric machine 1 1 traction interruption-free, namely. with the help of
elektromotorischen Gänge EM1 , EM2, die beim verbrennungsmotorischen Schalten als Stützgänge wirken. Ein solcher Schaltvorgang wird mit einem Öffnen der Trennkupplung 4 gestartet, um die Brennkraftmaschine 7 vom Getriebe 1 zu entkoppeln. Ein eingelegter elektromotorischer Stützgang stellt während des zwischen den verbrennungsmotorischen Gängen erfolgenden Schaltvorgangs einen Stützlastpfad bereit, der von der Elektromaschine 1 1 zur Antriebsseite verläuft. Während des Schaltvorgangs (das heißt die Brennkraftmaschine 7 ist mittels der Trennkupplung 4 vom Antriebsstrang abgekoppelt) kann somit die Elektromaschine 1 1 ein Antriebsmoment erzeugen, das über den Stütz-Lastpfad zur Abtriebsseite übertragen wird. electromotive gears EM1, EM2, which act as support gears during internal combustion engine switching. Such a switching operation is started with an opening of the separating clutch 4 in order to decouple the internal combustion engine 7 from the transmission 1. An engaged electromotive support gear provides during the switching process between the internal combustion engine gear shifting a supporting load path that extends from the electric machine 1 1 to the drive side. During the switching process (that is, the internal combustion engine 7 is decoupled from the drive train by means of the disconnect clutch 4), the electric machine 1 1 can thus generate a drive torque, which is transmitted via the support load path to the output side.
Der obige Sachverhalt ist nachfolgend anhand eines The above facts are described below with reference to a
Zugkraftunterbrechungsfreien Schaltvorgangs zwischen dem dritten und vierten verbrennungsmotorischen Gang erläutert, bei dem der Traction interruption-free switching operation between the third and fourth internal combustion engine gear explained, in which the
elektromotorische zweite Gang EM2 als Stützgang wirkt: So ist im Getriebe 1 der Figur 1 im verbrennungsmotorischen dritten Gang VM3 das electromotive second gear EM2 acts as a support gear: Thus, in the transmission 1 of Figure 1 in the internal combustion engine third gear VM3 the
Schaltelement SE-F nach rechts und das Schaltelement SE-D nach links geschaltet. Dadurch verläuft ein Lastpfad von der Brennkraftmaschine 7, dem Teilgetriebe T1 , der Abtriebswelle 17 bis zum abtriebsseitigen  Switching element SE-F to the right and the switching element SE-D to the left. As a result, a load path extends from the internal combustion engine 7, the partial transmission T1, the output shaft 17 to the output side
Stirnradtrieb St, während das Teilgetriebe T2 deaktiviert (stillgelegt) ist. Zu Beginn des Schaltvorgangs wird die Trennkupplung 4 gelöst und das Schaltelement SE-D in seine Neutralstellung geschaltet. Zudem wird der als Stützgang wirkende elektromotorische Gang EM2 eingelegt, das heißt die Lamellenkupplung K2 geschlossen und das Schaltelement SE-E nach links geschaltet, und die Elektromaschine 1 1 hochgefahren. Dadurch erfolgt eine Lastübertragung von der Elektromaschine 1 1 zur Abtriebswelle 17, bei der die Elektromaschine 1 1 ein beliebig einstellbares Moment erzeugt. Spur gear St, while the partial transmission T2 is deactivated (shut down). At the beginning of the switching operation, the separating clutch 4 is released and the Switching element SE-D switched to its neutral position. In addition, acting as a support gear electromotive gear EM2 is inserted, that is, the multi-plate clutch K2 is closed and the switching element SE-E switched to the left, and the electric machine 1 1 started up. This results in a load transfer from the electric machine 1 1 to the output shaft 17, in which the electric machine 1 1 generates an arbitrarily adjustable torque.
Der Schaltvorgang in den Zielgang VM4 wird fortgesetzt, indem das The shift into the target gear VM4 is continued by the
Schaltelement SE-D von seiner Neutralstellung nach rechts geschaltet wird. Damit ist ein Lastpfad von der Brennkraftmaschine 7 über das Schaltelement SE-F, die Radebene V4, das Schaltelement SE-D sowie die Abtriebswelle 17 bis zum abtriebsseitigen Stirnradtrieb St vorbereitet. Zum Ende des Switching element SE-D is switched from its neutral position to the right. Thus, a load path of the internal combustion engine 7 via the switching element SE-F, the gear plane V4, the switching element SE-D and the output shaft 17 is prepared to the output side spur gear St. At the end of the
Schaltvorgangs wird die Trennkupplung 4 wieder geschlossen, das heißt die Brennkraftmaschine 7 zugeschaltet, sowie die Elektromaschine 1 1 wieder heruntergefahren, so dass der Zielgang VM4 geschaltet ist und abermals eine Lastübertragung von der Brennkraftmaschine 7 zur Abtriebsseite erfolgt. Switching operation, the clutch 4 is closed again, that is, the internal combustion engine 7 is switched on, and the electric machine 1 1 shut down again, so that the target gear VM4 is switched and again a load transfer from the engine 7 takes place to the output side.
Von daher kann im Getriebe 1 der Figur 1 jede Schaltung mittels eines elektromotorischen Stützgangs gestützt werden. Therefore, in the transmission 1 of Figure 1, each circuit can be supported by means of an electromotive support gear.
Zudem ist mittels des in der Figur 1 gezeigten Getriebes 1 ein In addition, by means of the transmission 1 shown in Figure 1 a
elektromotorisches Anfahren aus dem Fahrzeugstillstand oder ein Boost- Betrieb ermöglicht, bei der für einzelne verbrennungsmotorische Gänge mehrere elektromotorische Gänge zum Boosten zur Verfügung stehen. electromotive starting from the vehicle standstill or a boost mode allows in which for individual internal combustion engine gears several electromotive gears are available for boosting.
Anhand der folgenden Figuren 2 und 3 sind Abwandlungen des in der Figur 1 gezeigten Getriebes 1 beschrieben: So sind in der Figur 2 die beiden elektromaschinenseitigen Zahnräder 27, 29 der Hybrid-Radebenen E1 , E2 nicht über eine Doppelkupplung (Figur 1 ) mit der Elektromaschinen-Welle 9 verbindbar, sondern anstelle dessen mittels einer Freilaufkupplung F und einer Lamellenkupplung K. Die Modifications of the transmission 1 shown in FIG. 1 are described with reference to the following FIGS. 2 and 3: Thus, in FIG. 2, the two gear wheels 27, 29 of the hybrid gear planes E1, E2 can not be connected to the electric machine shaft 9 via a double clutch (FIG. 1), but instead by means of an overrunning clutch F and a multi-plate clutch K.
Lamellenkupplung K weist einen Außenlamellenträger 45 auf, der sowohl an der Elektromaschinen-Welle 9 als auch an der Hohlwelle 51 drehfest angebunden ist. Der Außenlamellenträger 45 wirkt auf einen Multi-disc clutch K has an outer disc carrier 45, which is rotatably connected both to the electric machine shaft 9 and to the hollow shaft 51. The outer disk carrier 45 acts on a
Innenlamellenträger 47. Dieser ist zusammen mit dem Inner disk carrier 47. This is together with the
elektromaschinenseitigen Zahnrad 29 der Hybrid-Ebene 1 auf der Vollwelle 53 drehfest angeordnet, die sich koaxial durch die Hohlwelle 51 erstreckt. Das Zahnrad 27 der ersten Hybridradebene E1 ist über die Freilaufkupplung F mit der Hohlwelle 51 verbindbar. Der Freilaufkupplung F ist ein Hybrid side 1 of the hybrid plane 1 on the solid shaft 53, which extends coaxially through the hollow shaft 51. The gearwheel 27 of the first hybrid wheel plane E1 can be connected to the hollow shaft 51 via the one-way clutch F. The one-way clutch F is a
Schaltelement SE-I zugeordnet, das in zwei Betriebsstellungen schaltbar ist: In der gezeigten Betriebsstellung ist eine Drehmomentübertragung von der Elektromaschinen-Welle 9 über den Außenlamellenträger 45 und über die Hohlwelle 51 in Richtung auf das Zahnrad 27 der ersten Hybrid-Radebene E1 ermöglicht und in Gegenrichtung die Freilauffunktion aktiviert, das heißt eine Drehmomentübertragung unterbunden. Sofern also die mit der Assigned switching element SE-I, which is switchable in two operating positions: In the operating position shown, a torque transmission from the electric machine shaft 9 via the outer disk carrier 45 and the hollow shaft 51 in the direction of the gear 27 of the first hybrid wheel plane E1 allows and Counter direction enabled the freewheeling function, that is, a torque transmission prevented. So if so with the
Hohlwelle 51 verbundene Freilaufkupplungs-Innenseite 58 schneller dreht als das Zahnrad 27, treibt die Hohlwelle 51 das Zahnrad 27 an. In einer zweiten Betriebsstellung ist das Schaltelement SE-I in der Figur 2 nach links geschaltet. In diesem Fall ist eine Drehmomentübertragung in beiden Hollow shaft 51 connected freewheel clutch inside 58 rotates faster than the gear 27, the hollow shaft 51 drives the gear 27 at. In a second operating position, the switching element SE-I is switched to the left in FIG. In this case, torque transmission is in both
Richtungen ermöglicht. Sowohl in der Figur 2 als auch in der Figur 1 sind die elektromotorischen Gänge lastschaltbar. Directions possible. Both in the figure 2 and in the figure 1, the electromotive gears are powershifted.
In der Figur 3 ist die Elektromaschine 1 1 nicht mehr abtriebsseitig an das Getriebe 1 angebunden (wie in den Figuren 1 und 2), sondern antriebsseitig an das Getriebe 1 angebunden. Bei einer solchen antriebsseitigen In FIG. 3, the electric machine 1 1 is no longer connected to the transmission 1 on the output side (as in FIGS. 1 and 2), but is connected to the transmission 1 on the drive side. In such a drive side

bereitgestellt, bei dem die Elektromaschine 1 1 in umgekehrter Richtung zu betreiben ist. provided in which the electric machine 1 1 is to be operated in the reverse direction.
In der Figur 4 ist eine Abwandlung der in der Figur 3 gezeigten FIG. 4 shows a modification of that shown in FIG
Getriebestruktur gezeigt. Demzufolge ist das elektromaschinenseitige Zahnrad 27 der ersten Hybrid-Radebene E1 , wie in der Figur 3, abtriebsseitig angebunden, d.h. es kämmt mit dem zugeordneten abtriebsseitigen Zahnrad 19 der Hybrid-Radebene E1 . Im Unterschied zur Figur 3 ist jedoch in der Figur 4 das elektromaschinenseitige Zahnrad 29 der zweiten Hybrid- Radebene E2 nicht mehr in Zahneingriff mit dem zugeordneten Transmission structure shown. Accordingly, the electric machine-side gear 27 of the first hybrid gear plane E1, as shown in Figure 3, connected on the output side, i. it meshes with the associated output-side gear 19 of the hybrid gear plane E1. In contrast to FIG. 3, however, in FIG. 4 the gear wheel 29 of the second hybrid gear plane E2 on the side of the electric machine is no longer in meshing engagement with the associated one
abtriebsseitigen Zahnrad 21 der zweiten Hybrid-Radebene E2, sondern vielmehr antriebsseitig angebunden. Diese antriebsseitige Anbindung ist in der Figur 4 mittels eines gestrichelten Doppelpfeils veranschaulicht, der eine triebliche Verbindung zwischen dem elektromaschinenseitigen Zahnrad 29 und dem antriebsseitigen Zahnrad 25 der zweiten Hybrid-Radebene E2 darstellen soll. output-side gear 21 of the second hybrid gear plane E2, but rather connected on the drive side. This drive-side connection is illustrated in the figure 4 by means of a dashed double arrow, which is intended to represent a driving connection between the electric machine side gear 29 and the drive-side gear 25 of the second hybrid gear plane E2.
