Definitions

  • the invention relates to a drive device for a motor vehicle with a drive unit, which acts via a drive wheel on a arranged in an axle bridge differential gear and two output shafts, as well as acting as an electric motor and / or generator electric machine.
  • a drive device it is known to arrange two electric machines, which are each connected via a planetary gear stage drivingly connected to an output shaft.
  • the drive unit is an internal combustion engine whose performance can be supported by the electric machine. It is also possible that the vehicle is driven only by the electric machine. When driving downhill and during braking operation, the electric machine can be operated as a generator and charge a battery through which later the electric machine can be operated as a drive. This training requires a complex structure and thus a large amount of space.
  • the object of the invention is therefore to provide a drive device for a motor vehicle, which requires a small space as a mild hybrid with a high performance summation of drive unit and electric machine.
  • This object is achieved in that the only electric machine is drivingly connected via a first gear stage with the drive wheel or the differential carrier of the differential gear.
  • the vehicle is preferably a bus.
  • the structure Since only a single electric machine is needed to support both output shafts, the structure is inexpensive and requires only a small space.
  • the first gear stage and / or the other gear stages may be spur gears whose structure is simple and requires a small space.
  • the electric machine and / or the first gear stage and / or one or more of the further gear stages can be arranged wholly or partly in the axle bridge.
  • the electric machine and / or the first gear stage and / or one or more of the other gear stages are arranged wholly or partially outside the axle bridge.
  • the electric machine can be arranged longitudinally to the vehicle longitudinal direction or transversely to the vehicle longitudinal direction.

Description

Antriebsvorrichtung für ein Kraftfahrzeug  Drive device for a motor vehicle
Die Erfindung bezieht sich auf eine Antriebsvorrichtung für ein Kraftfahrzeug mit einem Antriebsaggregat, das über ein Antriebsrad auf ein in einer Achsbrücke angeordnetes Differentialgetriebe und auf zwei Abtriebswellen wirkt, sowie mit einer als Elektromotor und/oder Generator wirkenden Elektromaschine. The invention relates to a drive device for a motor vehicle with a drive unit, which acts via a drive wheel on a arranged in an axle bridge differential gear and two output shafts, as well as acting as an electric motor and / or generator electric machine.
Bei einer derartigen Antriebsvorrichtung ist es bekannt zwei Elektromaschinen anzuordnen, die jeweils über eine Planetengetriebestufe antriebsmäßig mit einer Abtriebswelle verbunden sind. Das Antriebsaggregat ist dabei ein Verbrennungsmotor, dessen Leistung durch die Elektromaschine unterstützt werden kann. Auch ist es möglich, daß das Fahrzeug nur durch die Elektromaschine angetrieben wird. Bei Bergabfahrt sowie beim Bremsbetrieb kann die Elektromaschine als Generator betrieben werden und einen Akkumulator aufladen, durch den später die Elektromaschine als Antrieb betrieben werden kann. Diese Ausbildung benötigt einen aufwendigen Aufbau und damit auch einen großen Bauraum. In such a drive device, it is known to arrange two electric machines, which are each connected via a planetary gear stage drivingly connected to an output shaft. The drive unit is an internal combustion engine whose performance can be supported by the electric machine. It is also possible that the vehicle is driven only by the electric machine. When driving downhill and during braking operation, the electric machine can be operated as a generator and charge a battery through which later the electric machine can be operated as a drive. This training requires a complex structure and thus a large amount of space.
Aufgabe der Erfindung ist es daher eine Antriebsvorrichtung für ein Kraftfahrzeug zu schaffen, die als Mildhybrid bei einer hohen Leistungssummierung von Antriebsaggregat und Elektromaschine einen geringen Bauraum benötigt. The object of the invention is therefore to provide a drive device for a motor vehicle, which requires a small space as a mild hybrid with a high performance summation of drive unit and electric machine.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die einzige Elektromaschine über eine erste Getriebestufe mit dem Antriebsrad oder dem Differentialkorb des Differentialgetriebes antriebsmäßig verbunden ist.. This object is achieved in that the only electric machine is drivingly connected via a first gear stage with the drive wheel or the differential carrier of the differential gear.
Das Fahrzeug ist vorzugsweise ein Bus. The vehicle is preferably a bus.
Da nur eine einzige Elektromaschine zur Unterstützung beider Abtriebswellen benötigt wird, ist der Aufbau wenig aufwendig und benötigt nur einen geringen Bauraum. Since only a single electric machine is needed to support both output shafts, the structure is inexpensive and requires only a small space.
Ist die einzige Elektromaschine zusätzlich zur ersten Getriebestufe über wenigstens eine weitere Getriebestufe mit dem Antriebsrad oder dem Differentialkorb des Differentialgetriebes antriebsmäßig verbunden, kann der erforderliche Bauraum weiter verringert werden. Die erste Getriebestufe und/oder die weiteren Getriebestufen können Stirnradstufen sein, deren Aufbau einfach ist und einen geringen Bauraum erfordert. If the only electric machine, in addition to the first gear stage, is drivingly connected to the drive wheel or the differential cage of the differential gear via at least one further gear stage, the required installation space can be further reduced. The first gear stage and / or the other gear stages may be spur gears whose structure is simple and requires a small space.
Sind die erste Getriebestufe und/oder die weiteren Getriebestufen Planetengetriebestufen, so ist bei geringem Bauraumbedarf eine wesentliche Drehzahlreduzierung der Drehzahl der Elektromaschine erreichbar. If the first gear stage and / or the further gear stages planetary gear stages, so with a small space requirement, a significant speed reduction of the speed of the electric machine can be achieved.
Ebenfalls nur geringen Bauraum erfordernd kann die Elektromaschine und/oder die erste Getriebestufe und/oder eine oder mehrere der weiteren Getriebestufen ganz oder teilweise in der Achsbrücke angeordnet sein. Also requiring only small installation space, the electric machine and / or the first gear stage and / or one or more of the further gear stages can be arranged wholly or partly in the axle bridge.
Es ist aber auch möglich, daß die Elektromaschine und/oder die erste Getriebestufe und/oder eine oder mehrere der weiteren Getriebestufen ganz oder teilweise außerhalb der Achsbrücke angeordnet sind. But it is also possible that the electric machine and / or the first gear stage and / or one or more of the other gear stages are arranged wholly or partially outside the axle bridge.
Je nach dem vorhandenen Bauraum kann die Elektromaschine längs zur Fahrzeuglängsrichtung oder quer zur Fahrzeuglängsrichtung angeordnet sein. Depending on the available space, the electric machine can be arranged longitudinally to the vehicle longitudinal direction or transversely to the vehicle longitudinal direction.
In dem vom Antriebsaggregat zum Antriebsrad führenden Antriebsstrang kann eine im Normalbetrieb der Antriebsvorrichtung geschlossene offenbare Kupplung angeordnet sein. In the drive train leading from the drive unit to the drive wheel, an open clutch which is closed during normal operation of the drive device can be arranged.
Durch Öffnen der Kupplung ist ein Stopp/Start-Betrieb möglich. By opening the clutch, a stop / start operation is possible.
In dem Antriebsstrang von dem Antriebsaggregat zum Antriebsrad kann eine Bremse angeordnet sein. In the drive train from the drive unit to the drive wheel, a brake may be arranged.
Zum rein elektromotorischen Fahren wird die bei Normalbetrieb geschlossene Kupplung geöffnet und die Bremse festgesetzt. For purely electric motor driving the closed during normal operation clutch is opened and fixed the brake.

Figur 11 ein elftes Ausführungsbeispiel einer Prinzipdarstellung einer Achsbrücke im Bereich eines Differentialgetriebes im Längsschnitt. Die Figuren zeigen Ausschnitte von Achsbrücken eines Kraftfahrzeugs, das vorzugsweise ein Bus ist. Figure 11 shows an eleventh embodiment of a schematic diagram of an axle in the range of a differential gear in a longitudinal section. The figures show sections of axle bridges of a motor vehicle, which is preferably a bus.
Die Achsbrücken weisen ein als Au ßenkegelzahnrad ausgebildetes Antriebsrad 1 auf, das von einem Antriebsaggregat 2, nämlich einem Verbrennungsmotor, drehbar antreibbar ist. Das Antriebsrad ist dabei um eine sich in Fahrzeuglängsrichtung 3 erstreckende Drehachse 4 drehbar. The axle bridges have a drive wheel 1 designed as an outer bevel gear, which can be driven rotatably by a drive unit 2, namely an internal combustion engine. The drive wheel is rotatable about an axis of rotation 4 extending in the vehicle longitudinal direction 3.
Das Antriebsrad 1 greift in ein Außenkegelrad 5 eines in einer Achsbrücke 6 angeordneten Differentialgetriebes 7 ein, das um eine sich quer zur Fahrzeuglängsrichtung 3 erstreckende zweite Drehachse 8 drehbar gelagert ist. The drive wheel 1 engages in a Außenkegelrad 5 of a arranged in a axle 6 differential gear 7, which is rotatably mounted about a transverse to the vehicle longitudinal direction 3 extending second axis of rotation 8.
Mit dem Außenkegelrad 5 ist ein Differentialkorb 9 fest verbunden, an dem sich diametral gegenüberliegend zwei Ausgleichskegelräder 10, 10' um eine sich in Fahrzeuglängsrichtung 3 erstreckende dritte Drehachse 1 1 drehbar gelagert sind. With the external bevel gear 5, a differential cage 9 is fixedly connected to the diametrically opposite two bevel gears 10, 10 'are mounted rotatably about a third axis of rotation 1 1 extending in the vehicle longitudinal direction 3.
In die Ausgleichskegelräder 10, 10' greifen zwei sich ebenfalls diametral gegenüberliegende Achswellenkegelräder 12, 12' ein, wobei das Achswellenkegelrad 12 auf einer linken Abtriebswelle 17 und das Achswellenkegelrad 12' auf einer Abtriebswelle 17' drehfest angeordnet ist. Die Abtriebswellen 17 und 17' erstrecken sich voneinander weg zu nicht dargestellten Rädern des Fahrzeugs. In the bevel gears 10, 10 'engage two likewise diametrically opposite Achswellenkegelräder 12, 12', wherein the Achswellenkegelrad 12 on a left output shaft 17 and the Achswellenkegelrad 12 'on an output shaft 17' is arranged rotationally fixed. The output shafts 17 and 17 'extend away from each other to unillustrated wheels of the vehicle.
Weiterhin ist eine Elektromaschine 13 vorhanden, die sowohl im Motorbetrieb als auch im Generatorbetrieb betreibbar ist und mit der das Antriebsrad 1 oder eine Komponente des Differentialgetriebes 7 über einen Nebenabtrieb verbunden ist. Furthermore, an electric machine 13 is present, which is operable both in engine operation and in generator operation and with which the drive wheel 1 or a component of the differential gear 7 is connected via a power take-off.
Bei dem Ausführungsbeispiel der Figur 1 ist die Elektromaschine 13 quer zur Fahrzeuglängsrichtung 3 angeordnet und befindet sich in Fahrzeuglängsrichtung 3 vor dem Differentialgetriebe 7. Über eine eine erste Getriebestufe bildende erste Planetengetriebestufe 14 an der Elektromaschine 13 wird die Drehzahl der als Motor betriebenen Elektromaschine 13 reduziert und die Leistung der Elektromaschine 13 mit einer zur ersten Planetenradstufe 14 koaxialen, eine zweite Getriebestufe bildenden ersten Stirnradstufe 15 übersetzt auf den Differentialkorb 9 des Differentialgetriebes 7 übertragen. Im Differentialkorb 9 wird dann die vom Verbrennungsmotor ggf. über ein nicht dargestelltes Schaltgetriebe kommende Verbrennungsmotorleistung mit der Elektroma- schinenleistung summiert und über die Antriebswellen 17, 17' auf die nicht dargestellten Räder des Kraftfahrzeugs weitergeleitet. In the embodiment of Figure 1, the electric machine 13 is arranged transversely to the vehicle longitudinal direction 3 and located in the vehicle longitudinal direction 3 in front of the differential gear 7. About a first gear stage forming first planetary gear stage 14 on the electric machine 13, the speed of the motor operated as an electric motor 13 is reduced and the power of the electric machine 13 with a coaxial to the first planetary gear 14, a second gear stage forming the first spur gear 15 translated to the differential carrier 9 of the differential gear 7 transmitted. In the differential carrier 9, the internal combustion engine, possibly via an unillustrated manual transmission engine output is then summed with the electrical machine performance and forwarded via the drive shafts 17, 17 'to the wheels, not shown, of the motor vehicle.
Wird über das Schaltgetriebe der Verbrennungsmotor von dem Triebstrang zum Differentialgetriebe 7 entkoppelt, kann das Kraftfahrzeug auch rein elektrisch von der im Motorbetrieb betriebenen Elektromaschine 13 angetrieben werden, insbesondere, wenn nur kurze Strecken zu fahren sind. If the internal combustion engine is decoupled from the drive train to the differential gear 7 via the gearbox, the motor vehicle can also be driven purely electrically by the electric machine 13 operated during engine operation, in particular if only short distances are to be traveled.
Die Elektromaschine ist in Fahrzeuglängsrichtung 3 vor der Achsbrücke 6 angeordnet, so daß kein wesentlicher zusätzlicher Bauraum dafür erforderlich ist. The electric machine is arranged in the vehicle longitudinal direction 3 in front of the axle 6, so that no significant additional space is required for it.
Durch die Summierung der Verbrennungsmotorleistung mit der Elektromaschinen- leistung ist es möglich einen kleineren Verbrennungsmotor zu verwenden, was wiederum zu einer Reduzierung des erforderlichen Bauraums sowie zu einer Kraftstoffeinsparung führt. Da sich gleichzeitig auch die Betriebstemperatur des Verbrennungsmotors erhöht, kann die Abgasanlage des Kraftfahrzeugs optimal betrieben werden, was einen vorzeitigen Ausfall oder eine vorzeitige Wartung vermeidet. By summing the engine power with the electric machine power, it is possible to use a smaller internal combustion engine, which in turn leads to a reduction of the required installation space and to fuel savings. Since at the same time the operating temperature of the internal combustion engine increases, the exhaust system of the motor vehicle can be optimally operated, which avoids premature failure or premature maintenance.
Das in Figur 2 dargestellte Ausführungsbeispiel entspricht weitgehend dem Ausführungsbeispiel der Figur 1 . Im Unterschied dazu ist eine von der Elektromaschine 13 antreibbare erste Getriebestufe von einer zweiten Stirnradstufe 18 und die weitere Getriebestufe durch eine dritte Stirnradstufe 19 gebildet. Dadurch kann die Elektromaschine flexibel zum Antrieb der dritten Stirnradstufe 19 verdreht werden. The exemplary embodiment illustrated in FIG. 2 largely corresponds to the exemplary embodiment of FIG. 1. In contrast, a first gear stage which can be driven by the electric machine 13 is formed by a second spur gear stage 18 and the further gear stage is formed by a third spur gear stage 19. As a result, the electric machine can be flexibly rotated to drive the third spur gear 19.
Auch das Ausführungsbeispiel der Figur 3 entspricht weitgehend dem Ausführungsbeispiel der Figur 1 . Im Unterschied dazu ist die Elektromaschine 13 in Fahrzeuglängsrichtung 3 hinter der Achsbrücke 6 angeordnet. Dadurch kommt es nicht zu einer möglichen Kollision mit nicht dargestellten Dreiecksachslenkern des Kraftfahrzeugs. Das Ausführungsbeispiel der Figur 4 entspricht weitgehend dem Ausführungsbeispiel der Figur 2. Im Unterschied dazu ist wie in Figur 3 die Elektromaschine 13 in Fahrzeuglängsrichtung 3 hinter der Achsbrücke 6 angeordnet. Also, the embodiment of Figure 3 largely corresponds to the embodiment of Figure 1. In contrast, the electric machine 13 is arranged in the vehicle longitudinal direction 3 behind the axle 6. This does not lead to a possible collision with triangular axle links, not shown, of the motor vehicle. The embodiment of Figure 4 largely corresponds to the embodiment of Figure 2. In contrast, as in Figure 3, the electric machine 13 is arranged in the vehicle longitudinal direction 3 behind the axle 6.
Bei dem Ausführungsbeispiel der Figur 5 ist die Elektromaschine 13 längs zur Fahrzeuglängsrichtung 3 angeordnet. Die Elektromaschine 13 liegt dabei in Fahrzeuglängsrichtung 3 vor der Achsbrücke 6. Über eine eine erste Getriebestufe bildende erste Planetengetriebestufe 14 an der Elektromaschine 13 wird die Drehzahl der als Motor betriebenen Elektromaschine 13 reduziert und mit einer zur ersten Pla- netenradstufe 14 koaxialen, eine zweite Getriebestufe bildenden ersten Stirnradstufe 15 übersetzt die Leistung der Elektromaschine auf das Antriebsrad 1 übertragen. In the embodiment of Figure 5, the electric machine 13 is arranged along the vehicle longitudinal direction 3. The electric machine 13 lies in front of the axle bridge 6 in the vehicle longitudinal direction 3. The speed of the electric machine 13 operated as a motor is reduced via a first planetary gear stage 14 forming a first gear stage and a second gear stage coaxial with the first planetary gear stage 14 forming first spur gear 15 translates the power of the electric machine transmitted to the drive wheel 1.
An dem Antriebsrad 1 wird dann die vom Verbrennungsmotor kommende Leistung mit der von der Elektromaschine 13 kommenden Leistung summiert und auf das Differentialgetriebe 7 übertragen und über die Abtriebswellen 13, 13' auf die nicht dargestellten Räder des Kraftfahrzeugs weitergeleitet. On the drive wheel 1, the power coming from the internal combustion engine is then summed with the power coming from the electric machine 13 and transmitted to the differential gear 7 and transmitted via the output shafts 13, 13 'to the wheels of the motor vehicle, not shown.
Wird über das Schaltgetriebe der Verbrennungsmotor von dem Triebstrang zum Differentialgetriebe 7 entkoppelt, kann das Kraftfahrzeug auch rein elektrisch von der im Motorbetrieb betriebenen Elektromaschine 13 angetrieben werden, insbesondere, wenn nur kurze Strecken zu fahren sind. If the internal combustion engine is decoupled from the drive train to the differential gear 7 via the gearbox, the motor vehicle can also be driven purely electrically by the electric machine 13 operated during engine operation, in particular if only short distances are to be traveled.
Die Elektromaschine 13 ist in Fahrzeuglängsrichtung 3 vor der Achsbrücke 6 angeordnet, so daß kein wesentlicher zusätzlicher Bauraum dafür erforderlich ist. The electric machine 13 is arranged in the vehicle longitudinal direction 3 in front of the axle 6, so that no significant additional space is required for it.
Bei dem Ausführungsbeispiel der Figur 5 kann die komplette Achsübersetzung zum Reduzieren der Drehzahl der Elektromaschine 13 genutzt werden. In the embodiment of Figure 5, the complete axle ratio for reducing the speed of the electric machine 13 can be used.
Durch die Summierung der Verbrennungsmotorleistung mit der Elektromaschinen- leistung ist es möglich einen kleineren Verbrennungsmotor zu verwenden, was wiederum zu einer Reduzierung des erforderlichen Bauraums sowie zu einer Kraftstoffeinsparung führt. Da sich gleichzeitig auch die Betriebstemperatur des Verbrennungsmotors speziell im Stadtbuseinsatz erhöht, kann die Abgasanlage des Kraft- fahrzeugs optimal betrieben werden, was einen vorzeitigen Ausfall oder eine vorzeitige Wartung vermeidet. By summing the engine power with the electric machine power, it is possible to use a smaller internal combustion engine, which in turn leads to a reduction of the required installation space and to fuel savings. Since at the same time the operating temperature of the internal combustion engine increases, especially in city bus use, the exhaust system of the power plant can be optimally operated vehicle, which avoids premature failure or early maintenance.
Das Ausführungsbeispiel der Figur 6 entspricht weitgehend dem Ausführungsbeispiel der Figur 5. Im Unterschied dazu ist eine von der Elektromaschine 13 antreibbare erste Getriebestufe von einer zweiten Stirnradstufe 18 und die weitere Getriebestufe durch eine dritte Stirnradstufe 19 gebildet. Dadurch kann die Elektromaschine 13 flexibel zum Antrieb der dritten Stirnradstufe 19 verdreht werden.  The embodiment of Figure 6 largely corresponds to the embodiment of Figure 5. In contrast, one of the electric machine 13 driven first gear stage of a second spur gear 18 and the further gear stage by a third spur gear 19 is formed. As a result, the electric machine 13 can be flexibly rotated to drive the third spur gear stage 19.
Bei dem Ausführungsbeispiel der Figur 7 ist die Elektromaschine 13 längs zur Fahrzeuglängsrichtung 3 in Fahrzeuglängsrichtung 3 vor der Achsbrücke 6 angeordnet. Über eine eine erste Getriebestufe bildende erste Stirnradstufe 15 wird die Drehzahl der im Motorbetrieb betriebenen Elektromaschine 13 reduziert. Die Abtriebswelle 20 der ersten Stirnradstufe 15 geht auf ein Stirnrad 21 , welches zusammen mit einem au ßenverzahnten Hohlrad 22 eine weitere Übersetzung bildet. An dem Achseingang 23 des Antriebsrads 1 sitzt eine eine zweite Getriebestufe bildende Planetengetriebestufe 24. Die Planetenräder 25 der zweiten Planetengetriebestufe 24 sind mittels einem Steg 26 mit dem Achseingang 23 des Antriebsrades 1 verbunden. Das Sonnenrad 27 der zweiten Planetengetriebestufe 24 ist über eine Gelenkwelle 28 mit dem Antriebsaggregat 2 verbunden. Ein Teil der Leistung kommt somit von dem von einem Verbrennungsmotor gebildeten Antriebsaggregat 1 auf das Sonnenrad 27 der Planetengetriebestufe 24 und ein weiterer Teil der Leistung kommt von der Elektromaschine über das Hohlrad 22 auf die Planetengetriebestufe 24. Die beiden Leistungen werden in den Planetenrädern 25 summiert und auf den Achseingang 24 des Antriebsrades 1 übertragen. In the embodiment of Figure 7, the electric machine 13 is arranged along the vehicle longitudinal direction 3 in the vehicle longitudinal direction 3 in front of the axle 6. About a first gear stage forming the first spur gear 15, the rotational speed of the operated electric motor 13 is reduced. The output shaft 20 of the first spur gear 15 is based on a spur gear 21 which together with an au ßenverzahnten ring gear 22 forms a further translation. The planetary gears 25 of the second planetary gear stage 24 are connected by means of a web 26 with the axis input 23 of the drive wheel 1. The sun gear 27 of the second planetary gear stage 24 is connected via a propeller shaft 28 to the drive unit 2. Part of the power thus comes from the drive unit 1 formed by an internal combustion engine on the sun gear 27 of the planetary gear stage 24 and another part of the power comes from the electric machine via the ring gear 22 to the planetary gear stage 24. The two powers are summed in the planetary gears 25 and transmitted to the axis input 24 of the drive wheel 1.
Steht das Kraftfahrzeug still, dreht sich das Hohlrad 22 entgegen dem Sonnenrad 27, so daß die Planetenräder 25 relativ zum Antriebsrad 1 still stehen. Beim Anfahren wird die Drehzahl des Antriebsaggregats 2 erhöht und die Drehzahl der Elektromaschine 13 konstant gehalten, bis sich das Antriebsaggregat 2 in seinem optimalen Betriebspunkt befindet. Im weiteren Beschleunigungsvorgang wird die Drehzahl der Elektromaschine 13 verringert und dann umgekehrt, bis die geforderte Geschwindigkeit erreicht ist. Beim Verzögern des Kraftfahrzeugs erfolgt dies in umgekehrter Reihenfolge und die Bremsenergie kann dabei rekuperiert werden. Beim Stillstand des Kraftfahrzeugs kann die Leerlaufdrehzahl des Antriebsaggregats 2 zum Aufladen der Batterie des Kraftfahrzeugs genutzt werden. Dadurch ist keine Stopp/Start-Funktion des Antriebsaggregats 2 zur Energieeinsparung notwendig. If the motor vehicle is stationary, the ring gear 22 rotates counter to the sun gear 27, so that the planet gears 25 are stationary relative to the drive wheel 1. When starting the speed of the drive unit 2 is increased and the speed of the electric machine 13 is kept constant until the drive unit 2 is in its optimum operating point. In the further acceleration process, the rotational speed of the electric machine 13 is reduced and then reversed until the required speed is reached. When decelerating the motor vehicle, this is done in reverse order and the braking energy can be recuperated. When the motor vehicle is at a standstill, the idling speed of the drive unit 2 can be used to charge the battery of the motor vehicle. As a result, no stop / start function of the power plant 2 for energy saving is necessary.
Durch die Summierung der Verbrennungsmotorleistung mit der Elektromaschinen- leistung ist es möglich einen kleineren Verbrennungsmotor zu verwenden, was wiederum zu einer Reduzierung des erforderlichen Bauraums sowie zu einer Kraftstoffeinsparung führt. Da sich gleichzeitig auch die Betriebstemperatur des Verbrennungsmotors erhöht, kann die Abgasanlage des Kraftfahrzeugs optimal betrieben werden, was einen vorzeitigen Ausfall oder eine vorzeitige Wartung vermeidet. By summing the engine power with the electric machine power, it is possible to use a smaller internal combustion engine, which in turn leads to a reduction of the required installation space and to fuel savings. Since at the same time the operating temperature of the internal combustion engine increases, the exhaust system of the motor vehicle can be optimally operated, which avoids premature failure or premature maintenance.
Durch die erste Stirnradstufe 15 an der Elektromaschine kann diese zum Antrieb des Stirnrads 21 radial verdreht werden und dadurch eine optimale Nutzung des vorhandenen Bauraums erfolgen. By the first spur gear 15 on the electric machine it can be rotated radially to drive the spur gear 21 and thereby make optimal use of the available space.
Durch die Verzweigung der dem Antriebsrad 1 zugeführten Leistung ist eine stufenlose Variierung der Drehzahl des Antriebsrades 1 möglich, was auch einen Entfall eines konventionellen Schaltgetriebes im Antriebsstrang von dem Antriebsaggregat 2 zum Differentialgetriebe 7 ermöglicht. Due to the branching of the drive wheel 1 supplied power is a stepless variation of the rotational speed of the drive wheel 1 is possible, which also allows a omission of a conventional gearbox in the drive train from the drive unit 2 to the differential gear 7.
Das Ausführungsbeispiel der Figur 8 entspricht weitgehend dem Ausführungsbeispiel der Figur 7. Im Unterschied dazu ist zwischen dem Antriebsaggregat 2 und der Gelenkwelle 28 eine dritte Planetengetriebestufe 29 angeordnet, durch die eine Reduzierung der Achsübersetzung erfolgt. Dies verbessert die Lebensdauer der Antriebsvorrichtung. The embodiment of Figure 8 corresponds largely to the embodiment of Figure 7. In contrast, between the drive unit 2 and the propeller shaft 28, a third planetary gear 29 is arranged, through which there is a reduction of the axle ratio. This improves the life of the drive device.
Bei dem Ausführungsbeispiel der Figur 9 ist die Elektromaschine 13 längs zur Fahrzeuglängsrichtung 3 in Fahrzeuglängsrichtung 3 vor der Achsbrücke 6 angeordnet. Über eine eine erste Getriebestufe bildende erste Planetengetriebestufe 14 wird die Drehzahl der im Motorbetrieb betriebenen Elektromaschine 13 reduziert. Die Abtriebswelle 20 der ersten Planetengetriebestufe 14 geht auf ein Stirnrad 21 , welches zusammen mit einem außenverzahnten Hohlrad 22 eine weitere Übersetzung bildet. An dem Achseingang 23 des Antriebsrads 1 sitzt eine eine zweite Getriebestufe bildende Planetengetriebestufe 24. Die Planetenräder 25 der zweiten Planetengetrie- bestufe 24 sind mittels einem Steg 26 mit dem Achseingang 23 des Antriebsrades 1 verbunden. Das Sonnenrad 27 der zweiten Planetengetriebestufe 24 ist über eine Gelenkwelle 28 und eine dritte Stirnradstufe 19 mit dem Antriebsaggregat 2 verbunden. Ein Teil der Leistung kommt somit von dem von einem Verbrennungsmotor gebildeten Antriebsaggregat 1 über die dritte Stirnradstufe 19 auf das Sonnenrad 27 der zweiten Planetengetriebestufe 24 und ein weiterer Teil der Leistung kommt von der Elektromaschine über das Hohlrad 22 auf die zweite Planetengetriebestufe 24. Die beiden Leistungen werden in den Planetenrädern 25 summiert und auf den Achseingang 24 des Antriebsrades 1 übertragen. In the embodiment of Figure 9, the electric machine 13 is arranged along the vehicle longitudinal direction 3 in the vehicle longitudinal direction 3 in front of the axle 6. By means of a first planetary gear stage 14 forming a first gear stage, the rotational speed of the electric machine 13 operated during engine operation is reduced. The output shaft 20 of the first planetary gear 14 is based on a spur gear 21, which forms a further translation together with an externally toothed ring gear 22. At the axis input 23 of the drive wheel 1 sits a second gear stage forming planetary gear stage 24. The planet gears 25 of the second planetary gear level 24 are connected by means of a web 26 with the axis input 23 of the drive wheel 1. The sun gear 27 of the second planetary gear stage 24 is connected to the drive unit 2 via a propeller shaft 28 and a third spur gear stage 19. Part of the power thus comes from the drive unit 1 formed by an internal combustion engine via the third spur gear 19 to the sun gear 27 of the second planetary gear stage 24 and another part of the power comes from the electric machine via the ring gear 22 to the second planetary gear stage 24. The two services are summed in the planet gears 25 and transmitted to the axis input 24 of the drive wheel 1.
Diese Ausbildung ermöglicht eine kleinere Achsübersetzung, was zu einer verbesserten Lebensdauer führt. Darüber hinaus ergibt sich ein reduzierter Beugewinkel der Gelenkwelle 28. This design allows a smaller axle ratio, resulting in an improved life. In addition, there is a reduced flexion angle of the propeller shaft 28th
Das Ausführungsbeispiel der Figur 10 entspricht weitgehend dem Ausführungsbeispiel der Figur 9. Im Unterschied dazu ist zwischen dem Antriebsaggregat 2 und der Gelenkwelle 28 eine dritte Planetengetriebestufe 29 angeordnet. Damit ist eine kleinere Achsübersetzung realisierbar, wodurch die Lebensdauer verbessert wird. The embodiment of Figure 10 largely corresponds to the embodiment of Figure 9. In contrast, a third planetary gear 29 is disposed between the drive unit 2 and the propeller shaft 28. For a smaller axle ratio can be realized, whereby the service life is improved.
Das Ausführungsbeispiel der Figur 1 1 entspricht weitgehend dem Ausführungsbeispiel der Figur 10. Zusätzlich sind zwischen dem Antriebsaggregat und der dritten Planetengetriebestufe 29 eine Kupplung 30 und eine Bremse 31 angeordnet. The embodiment of Figure 1 1 largely corresponds to the embodiment of Figure 10. In addition, a clutch 30 and a brake 31 are arranged between the drive unit and the third planetary gear stage 29.
Zum rein elektromotorischen Fahren wird die bei Normalbetrieb geschlossene Kupplung 30 geöffnet und die Bremse 31 festgesetzt. For purely electric motor driving the closed during normal operation clutch 30 is opened and the brake 31 fixed.
Außerdem kann durch Öffnen der Kupplung ein Stopp/Start-Betrieb ermöglicht werden, wodurch der Fahrzeugenergiehaushalt optimal eingestellt werden kann, da das Antriebsaggregat unabhängig ein- und abgeschaltet werden kann. Bezugszeichen Antriebsrad In addition, a stop / start operation can be made possible by opening the clutch, whereby the vehicle energy budget can be optimally adjusted because the drive unit can be independently switched on and off.
