Die Erfindung betrifft einen Antriebsstrang für ein Kraftfahrzeug, insbesondere für ein Hybridfahrzeug, gemäß dem jeweiligen Oberbegriff von Patentanspruch 1 beziehungsweise 7.The invention relates to a drive train for a motor vehicle, in particular for a hybrid vehicle, according to the respective preamble of patent claims 1 and 7, respectively.

Ein solcher Antriebsstrang für ein Kraftfahrzeug, insbesondere für ein Hybridfahrzeug, ist beispielsweise bereits der DE 10 2009 050 957 A1 als bekannt zu entnehmen. Der Antriebsstrang weist wenigstens eine Verbrennungskraftmaschine sowie ein Hauptgetriebe auf, welches eine Getriebeglocke aufweist. Ferner umfasst der Antriebsstrang ein in der Getriebeglocke angeordnetes Anfahrelement, welches beispielsweise als hydrodynamischer Drehmomentwandler ausgebildet sein kann. Über das Anfahrelement sind von der Verbrennungskraftmaschine bereitgestellte Drehmoment in das Hauptgetriebe einleitbar. Ferner umfasst der Antriebsstrang eine Hinterachse, deren Räder von der Verbrennungskraftmaschine über das Hauptgetriebe und das Anfahrelement antreibbar sind. Darüber hinaus ist eine Vorderachse vorgesehen, welche in Fahrzeuglängsrichtung vor der Hinterachse angeordnet ist.Such a drive train for a motor vehicle, in particular for a hybrid vehicle, for example, is already the DE 10 2009 050 957 A1 to be known as known. The drive train has at least one internal combustion engine and a main transmission, which has a transmission bell. Further, the drive train comprises a arranged in the bell housing starting element, which may be formed for example as a hydrodynamic torque converter. About the starting element provided by the internal combustion engine torque can be introduced into the main transmission. Furthermore, the drive train comprises a rear axle whose wheels can be driven by the internal combustion engine via the main transmission and the starting element. In addition, a front axle is provided, which is arranged in the vehicle longitudinal direction in front of the rear axle.

Aufgabe der vorliegenden Erfindung ist es, einen Antriebsstrang der eingangs genannten Art derart weiterzuentwickeln, dass sich eine besonders kompakte Bauweise des Antriebsstrangs realisieren lässt.Object of the present invention is to develop a drive train of the type mentioned in such a way that a particularly compact design of the drive train can be realized.

Diese Aufgabe wird durch einen Antriebsstrang mit den Merkmalen des Patentanspruchs 1 sowie durch einen Antriebsstrang mit den Merkmalen des Patentanspruchs 7 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a drive train having the features of patent claim 1 and by a drive train having the features of patent claim 7. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

Um einen Antriebsstrang der eingangs genannten Art derart weiterzuentwickeln, dass sich eine besonders kompakte Bauform realisieren lässt, so dass der Bauraumbedarf des Antriebsstrangs besonders gering gehalten werden kann, sind erfindungsgemäß eine in der Getriebeglocke angeordnete elektrische Maschine und ein wenigstens eine Stufe aufweisendes Versatzgetriebe vorgesehen, über welches Räder der Vorderachse von der elektrischen Maschine antreibbar sind. Der Erfindung liegt insbesondere die Erkenntnis zugrunde, dass herkömmliche P2-Hybridsysteme den Nachteil mit sich bringen, dass von der elektrischen Maschine generierte beziehungsweise bereitgestellte Antriebsmomente ergänzend zu von der Verbrennungskraftmaschine bereitgestellten Antriebs- beziehungsweise Drehmomenten durch das Hauptgetriebe an die jeweiligen Räder geleitet werden müssen. Die von der elektrischen Maschine bereitgestellten Antriebsmomente werden auch als elektrisch generierte beziehungsweise elektrisch bereitgestellte Antriebsmomente bezeichnet.In order to develop a drive train of the type mentioned in such a way that a particularly compact design can be realized, so that the space requirement of the drive train can be kept particularly low, according to the invention arranged in the bell housing electric machine and at least one stage having offset gear, via which wheels of the front axle of the electric machine can be driven. The invention is based in particular on the recognition that conventional P2 hybrid systems have the disadvantage that drive torques generated or provided by the electric machine must be routed through the main transmission to the respective wheels in addition to drive or torque provided by the internal combustion engine. The drive torques provided by the electric machine are also referred to as electrically generated or electrically provided drive torques.

Kommt als die Verbrennungskraftmaschine eine besonders drehmomentstarke Verbrennungskraftmaschine zum Einsatz, so dass bereits lediglich die von der Verbrennungskraftmaschine bereitgestellten Drehmomente ohne zusätzliches Einleiten von von der elektrischen Maschine bereitgestellten Drehmomenten in das Hauptgetriebe ausreichen, um Bauteilgrenzen des Hauptgetriebes zu erreichen, kommt es zu dem Nachteil, dass die hier als elektrische Antriebsmaschine fungierende elektrische Maschine keine zusätzliche Antriebsleistung beziehungsweise keine zusätzlichen Antriebsmomente aufbringen kann. Diese Nachteile und Probleme können bei dem erfindungsgemäßen Antriebsstrang vermieden werden, da die Räder der Hinterachse von der Verbrennungskraftmaschine und somit verbrennungsmotorisch und die Räder der Vorderachse von der elektrischen Maschine und somit elektromotorisch angetrieben werden können. Da dabei die elektrische Maschine in der Getriebeglocke angeordnet ist, kann der Bauraumbedarf des Antriebsstrangs, insbesondere in Fahrzeuglängsrichtung, besonders gering gehalten werden.If a particularly high-torque internal combustion engine is used as the internal combustion engine, then only the torques provided by the internal combustion engine without additional introduction of torques provided by the electrical machine into the main transmission suffice to achieve component limits of the main transmission, there is the disadvantage that the electric machine operating here as the electric drive machine can not apply any additional drive power or additional drive torques. These disadvantages and problems can be avoided in the drive train according to the invention, since the wheels of the rear axle of the internal combustion engine and thus internal combustion engine and the wheels of the front axle of the electric machine and thus can be driven by an electric motor. Since in this case the electric machine is arranged in the transmission bell, the space requirement of the drive train, in particular in the vehicle longitudinal direction, can be kept particularly low.

Bei dem Anfahrelement handelt es sich beispielsweise um einen hydrodynamischen Drehmomentwandler, welcher auch einfach als Wandler bezeichnet wird. Somit handelt es sich bei der Getriebeglocke um eine sogenannte Wandlerglocke.The starting element is, for example, a hydrodynamic torque converter, which is also referred to simply as a converter. Thus, the transmission bell is a so-called converter bell.

Die mittels der elektrischen Maschine bereitgestellten Antriebs- beziehungsweise Drehmomente werden im Gegensatz zu herkömmlichen P2-Hybridsystemen über das Versatzgetriebe, insbesondere direkt, an die Vorderachse beziehungsweise deren Räder geleitet, so dass eine durch die elektrische Maschine beziehungsweise durch von der elektrischen Maschine bereitgestellte Drehmomente bewirkte Belastung des Hauptgetriebes unterbleibt. Es kann vorgesehen sein, dass das Versatzgetriebe wenigstens zwei oder demgegenüber mehrere Stufen aufweist, so dass die elektrische Maschine beispielsweise mit einem mehrstufigen Versatzgetriebe versehen ist, so dass ein besonders großer Betriebsbereich dargestellt werden kann.In contrast to conventional P2 hybrid systems, the drive or torques provided by means of the electrical machine are conducted via the offset gear, in particular directly, to the front axle or its wheels, so that a load caused by the electric machine or by torques provided by the electric machine of the main transmission is omitted. It can be provided that the offset gear has at least two or moreover several stages, so that the electric machine is provided, for example with a multi-stage offset gear, so that a particularly large operating range can be displayed.

Zur Erfindung gehört auch ein solcher Antriebsstrang, bei welchem es erfindungsgemäß vorgesehen ist, dass bezogen auf einen Drehmomentfluss von dem Hauptgetriebe zu der Hinterachse zwischen der Hinterachse und dem Hauptgetriebe wenigstens eine elektrische Maschine angeordnet ist, mittels welcher Räder der Vorderachse antreibbar sind. Dies bedeutet, dass die als elektrische Antriebsmaschine fungierende elektrische Maschine bezogen auf den Drehmomentfluss beziehungsweise in Fahrzeuglängsrichtung hinter dem Hauptgetriebe, insbesondere vollständig hinter dem Hauptgetriebe, angeordnet ist, wobei die elektrische Maschine an einer Stelle eines herkömmlicherweise zum Einsatz kommenden Verteilergetriebes eines Vierrad-Triebstrangs angeordnet ist. Hierdurch kann der Antriebsstrang als hybrider oder hybridisierter Antriebsstrang ausgebildet werden, wobei gleichzeitig der Bauraumbedarf des Antriebsstrangs, insbesondere in Fahrzeuglängsrichtung, besonders gering gehalten werden kann.The invention also includes such a drive train, in which it is provided according to the invention that based on a torque flow from the main transmission to the rear axle between the rear axle and the main gear at least one electric machine is arranged, by means of which wheels of the front axle can be driven. This means that the electrical machine acting as the electric drive machine with respect to the torque flow or in the vehicle longitudinal direction behind the Main transmission, in particular completely behind the main transmission, is arranged, wherein the electric machine is disposed at a position of a conventionally used for transfer case of a four-wheel drive train. In this way, the drive train can be formed as a hybrid or hybridized drive train, wherein at the same time the space requirement of the drive train, in particular in the vehicle longitudinal direction, can be kept particularly low.

Ferner umfasst der Antriebsstrang 10 ein in 1 nicht näher dargestelltes Anfahrelement, über welches von der Verbrennungskraftmaschine 12 bereitgestellte Drehmomente in das Hauptgetriebe 18 eingeleitet werden können. Bei dem Anfahrelement handelt es sich beispielsweise um einen hydrodynamischen Drehmomentwandler, welcher einfach auch als Wandler bezeichnet wird. Da der Wandler in der Getriebeglocke 20 angeordnet ist, wird die Getriebeglocke 20 auch als Wandlerglocke bezeichnet.Furthermore, the drive train includes 10 a whole with 18 designated main gear, which is a bell housing 20 having.

Die Hinterachse 24 umfasst dabei ein Differentialgetriebe 26, welches auch als Hinterachsgetriebe bezeichnet wird. Dabei sind die Hinterräder über das Differentialgetriebe 26 von der Verbrennungskraftmaschine 12 antreibbar. Wie aus dem allgemeinen Stand der Technik bekannt, dient das Differentialgetriebe 26, insbesondere bei einer Kurvenfahrt des Kraftfahrzeugs, dem Drehzahlausgleich zwischen den Hinterrädern. Der Antriebsstrang umfasst ferner eine Vorderachse 28, welche in Fahrzeuglängsrichtung beziehungsweise in Vorwärtsfahrtrichtung vor der Hinterachse 24 angeordnet ist und in 1 nicht näher dargestellte Räder aufweist, welche als Vorderräder bezeichnet werden.The rear axle 24 includes a differential gear 26 , which is also referred to as Hinterachsgetriebe.

The powertrain also includes a front axle 28 , which in the vehicle longitudinal direction or in the forward direction of travel in front of the rear axle 24 is arranged and in 1 not shown wheels, which are referred to as front wheels.

Um nun den Bauraumbedarf des Antriebsstrangs 10 besonders gering zu halten, und einen besonders vorteilhaften Betrieb des Antriebsstrangs 10 zu realisieren, umfasst der Antriebsstrang 10 eine elektrische Maschine 30, welche in der Wandlerglocke (Getriebeglocke 20) angeordnet ist. Ferner umfasst der Antriebsstrang 10 ein Versatzgetriebe 32, über welches die Vorderräder von der elektrischen Maschine 30 antreibbar sind. Dabei umfasst die Vorderachse ein Differentialgetriebe 34, welches auch als Vorderachsgetriebe bezeichnet wird. Dabei sind die Vorderräder über das Differentialgetriebe 34 und das Versatzgetriebe 32 von der elektrischen Maschine 30 antreibbar.Now to the space requirements of the powertrain 10 To keep particularly low, and a particularly advantageous operation of the drive train 10 To realize includes the powertrain 10 an electric machine 30 , which in the converter bell (gear bell 20 ) is arranged. Furthermore, the drive train includes 10 an offset gearbox 32 over which the front wheels of the electric machine 30 are drivable. The front axle comprises a differential gear 34 , which is also referred to as Vorderachsgetriebe. The front wheels are on the differential gear 34 and the offset gear 32 from the electric machine 30 drivable.

Die elektrische Maschine 30 umfasst einen Stator 36 und einen um eine Drehachse relativ zu dem Stator 36 drehbaren Rotor 38, wobei der Stator 36 und der Rotor 38 jeweils zumindest teilweise, insbesondere zumindest überwiegend oder vollständig, in der Getriebeglocke 20 aufgenommen sind. Das Versatzgetriebe 32 ist bei der in 1 gezeigten ersten Ausführungsform als einstufiges Versatzgetriebe ausgebildet und weist somit genau eine Stufe auf, welche auch als Getriebestufe bezeichnet wird. Hierzu umfasst das Versatzgetriebe 32 ein erstes Zahnrad 40 und ein mit dem ersten Zahnrad 40 in Eingriff stehendes zweites Zahnrad 42. Das zweite Zahnrad 42 ist drehfest mit einer Welle 44 verbunden, über welche das Differentialgetriebe 34 und somit die Vorderräder von der elektrischen Maschine 30 antreibbar sind. Dabei ist dem Rotor 38 beispielsweise eine Verzahnung zugeordnet, über welche der Rotor 38 in Eingriff mit dem Zahnrad 40 steht. Dadurch ist das Zahnrad 42 über das Zahnrad 40 von dem Rotor 38 antreibbar, so dass die Welle 44 über das Zahnrad 42 und das Zahnrad 40 von dem Rotor 38 antreibbar ist. Dies bedeutet, dass die elektrische Maschine 30 Drehmomente zum Antreiben des Kraftfahrzeugs, das heißt Antriebsmomente über den Rotor 38 bereitstellt. Die von der elektrischen Maschine 30 bereitgestellten Antriebsmomente werden über den Rotor 38 auf die Zahnräder 40 und 42 und über diese auf die Welle 44 übertragen.The electric machine 30 includes a stator 36 and one about an axis of rotation relative to the stator 36 rotatable rotor 38 , where the stator 36 and the rotor 38 in each case at least partially, in particular at least predominantly or completely, in the transmission bell 20 are included. The offset gear 32 is at the in 1 shown first embodiment as a single stage offset gear and thus has exactly one step, which is also referred to as gear stage. This includes the offset gear 32 a first gear 40 and one with the first gear 40 engaged second gear 42 , The second gear 42 is non-rotatable with a shaft 44 connected via which the differential gear 34 and thus the front wheels of the electric machine 30 are drivable. Here is the rotor 38 For example, associated with a toothing, via which the rotor 38 in engagement with the gear 40 stands. This is the gear 42 over the gear 40 from the rotor 38 drivable so that the shaft 44 over the gear 42 and the gear 40 from the rotor 38 is drivable. This means that the electric machine 30 Torques for driving the motor vehicle, that is drive torque via the rotor 38 provides. The of the electric machine 30 provided drive torques are transmitted through the rotor 38 on the gears 40 and 42 and about this on the wave 44 transfer.

Da die von der elektrischen Maschine 30 bereitgestellten Antriebsmomente auf die Vorderräder und die von der Verbrennungskraftmaschine 12 bereitgestellten Antriebsmomente auf die Hinterräder übertragen werden können, können zwei Drehmomentpfade, insbesondere zwei voneinander getrennte Drehmomentpfade, realisiert werden. Über einen ersten der Drehmomentpfade können die von der elektrischen Maschine 30 bereitgestellten Drehmomente auf die Vorderräder übertragen werden, so dass über den ersten Drehmomentpfad die Vorderräder angetrieben werden können. Dabei können die Vorderräder von der elektrischen Maschine 30 und somit elektrisch angetrieben werden. Über den zweiten Drehmomentpfad können die von der Verbrennungskraftmaschine 12 bereitgestellten Drehmomente auf die Hinterräder übertragen werden, so dass die Hinterräder über den zweiten Drehmomentpfad verbrennungsmotorisch angetrieben werden können.Because of the electric machine 30 provided driving torques on the front wheels and from the internal combustion engine 12 provided drive torque can be transmitted to the rear wheels, two torque paths, in particular two separate torque paths, can be realized. The first of the torque paths can be from the electric machine 30 provided torques are transmitted to the front wheels, so that over the first torque path, the front wheels can be driven. In this case, the front wheels of the electric machine 30 and thus electrically driven. The second torque path can be used by the internal combustion engine 12 provided torques are transmitted to the rear wheels, so that the rear wheels can be driven by the internal combustion engine via the second torque path.

Die zweite Ausführungsform unterscheidet sich insbesondere dadurch von der ersten Ausführungsform, dass das Versatzgetriebe 32 mehrstufig und vorliegend zweistufig ausgebildet ist. Dabei umfasst das Versatzgetriebe 32 die Zahnräder 40 und 42 sowie wenigstens ein Planetengetriebe 46. Das Planetengetriebe 46 umfasst ein Sonnenrad 48, welches mit einer Welle 50 des Planetengetriebes 46 drehfest verbunden ist. Dabei wird die Welle 50 auch als Sonnenwelle bezeichnet. Aus 1 und 2 ist erkennbar, dass beispielsweise der Rotor 38 als Hohlwelle ausgebildet ist beziehungsweise wenigstens eine Hohlwelle aufweist, durch welche die Abtriebswelle 16 hindurchgeführt werden kann, so dass die von der Verbrennungskraftmaschine 12 über die Abtriebswelle 16 bereitgestellten Drehmomente durch die Hohlwelle beziehungsweise durch den Rotor 38 hindurch in das Hauptgetriebe 18 eingeleitet werden können. Aus 2 ist erkennbar, dass die Welle 50 als Hohlwelle ausgebildet sein kann, durch welche die Abtriebswelle 16 hindurchgeführt ist. 2 shows a second embodiment of the drive train 10 , The second embodiment differs in particular from the first embodiment that the offset gear 32 multi-level and present two-stage is formed. This includes the offset gear 32 the gears 40 and 42 and at least one planetary gear 46 , The planetary gear 46 includes a sun wheel 48 which with a wave 50 of the planetary gear 46 rotatably connected.

Out 1 and 2 it can be seen that, for example, the rotor 38 is formed as a hollow shaft or at least has a hollow shaft through which the output shaft 16 can be passed, so that by the internal combustion engine 12 over the output shaft 16 provided torques through the hollow shaft or through the rotor 38 through the main gearbox 18 can be initiated. Out 2 is recognizable that the wave 50 may be formed as a hollow shaft through which the output shaft 16 passed through.

Das Planetengetriebe 46 umfasst ferner Planetenräder 52, welche mit dem Sonnenrad 48 in Eingriff stehen und drehbar an einem Planetenträger 54 des Planetengetriebes 46 gelagert sind. Der Planetenträger 54 ist beispielsweise, insbesondere drehbar, an der Welle 50 gelagert. Alternativ oder zusätzlich kann die Welle 50, insbesondere drehbar, an dem Getriebegehäuse, insbesondere an der Getriebeglocke 20, gelagert sein.The planetary gear 46 also includes planet gears 52 , which with the sun wheel 48 engage and rotatable on a planetary carrier 54 of the planetary gear 46 are stored.

Hierbei ist dem Rotor 38 beispielsweise ein Hohlrad 56 des Planetengetriebes 46 zugeordnet. Das Hohlrad 56 ist beispielsweise von dem Rotor 38 antreibbar und kann drehfest mit dem Rotor 38 verbunden sein. Dabei steht das Hohlrad 56 in Eingriff mit den Planetenrädern 52, so dass die Planetenräder 52 über das Hohlrad 56 von dem Rotor 38 und somit von der elektrischen Maschine 30 antreibbar sind.Here is the rotor 38 for example, a ring gear 56 of the planetary gear 46 assigned. The ring gear 56 is for example from the rotor 38 drivable and can rotatably with the rotor 38 be connected. This is the ring gear 56 in engagement with the planetary gears 52 so that the planetary gears 52 over the ring gear 56 from the rotor 38 and thus of the electric machine 30 are drivable.
