Die Erfindung betrifft einen elektrischen Fahrantrieb mit einem Antriebsmotor und einer Antriebsachse, zwischen die ein mit dem Antriebsmotor gekoppelter elektrischer Generator und ein mit der Antriebsachse gekoppelter elektrischer Fahrmotor geschaltet ist, wobei der Generator und der Fahrmotor miteinander elektrisch verbunden und durch eine Regeleinheit regelbar sind.The invention relates to an electric travel drive with a drive motor and Drive axis, between which an electrical coupled to the drive motor Generator and an electric drive motor coupled to the drive axle is, wherein the generator and the traction motor are electrically connected to each other and can be regulated by a control unit.
Ein derartiger Fahrantrieb kommt bei den Flurförderzeugen der STILL GmbH, Hamburg, des Typs R70 zum Einsatz.Such a traction drive comes with the industrial trucks from STILL GmbH, Hamburg, type R70.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Fahrantrieb der ein gangs genannten Art insbesondere im Hinblick auf eine Reduzierung des Montage aufwands vereinfachen.The present invention is based on the object of a travel drive gangs mentioned in particular with regard to a reduction in assembly simplify effort.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Generator und der Fahrmotor zu einem eine gemeinsame Baueinheit bildenden Elektro-Wandler zusam mengefasst sind.This object is achieved in that the generator and the Drive motor together to form a common structural unit electrical converter are quantified.
Die erfindungswesentliche Integration von Generator und Fahrmotor zu einer gemein samen Baueinheit führt zu einer Reihe von Vorteilen: Anstelle zweier getrennt zu montierender und am Fahrzeug zu befestigender Baugruppen muß lediglich der erfindungsgemäße Elektro-Wandler montiert und in das Fahrzeug eingebaut werden. Darüber hinaus vereinfacht sich auch die Bauteilprüfung vor dem Einbau in das Fahrzeug, da nicht - wie bisher - getrennte Komponenten separat geprüft werden müssen. Die Prüfung der gemeinsamen Baueinheit ist weniger zeitaufwendig. The integration of generator and traction motor essential to the invention to a common The same structural unit leads to a number of advantages: Instead of two separate ones assemblies and to be attached to the vehicle only the electric converter according to the invention are mounted and installed in the vehicle. In addition, component testing before installation in the is simplified Vehicle because separate components are not tested separately, as has been the case up to now have to. Checking the common assembly is less time consuming.
Der erfindungsgemäße Elektro-Wandler kann beispielsweise dadurch hergestellt werden, daß der Generator mit dem Fahrmotor verschraubt wird. Gemäß einer vor teilhaften Ausgestaltung der Erfindung ist es jedoch auch eine Ausführung möglich, bei der der Elektro-Wandler ein für den Generator und den Fahrmotor gemeinsames Ge häuse aufweist. Eine solche Konstruktion hat einen nochmals verringerten Fertigungs- und Montageaufwand. Darüber hinaus ist ein gemeinsames Gehäuse steifer als zwei miteinander verbundene Einzelgehäuse. Maßnahmen zur Geräuschdämpfung sind einfacher möglich. Die Herstellungskosten werden reduziert.The electrical converter according to the invention can be produced, for example, by this that the generator is screwed to the drive motor. According to one before partial embodiment of the invention, however, it is also possible to carry out that of the electrical converter is a common ge for the generator and the drive motor has housing. Such a construction has a further reduced manufacturing and assembly effort. In addition, a common housing is stiffer than two interconnected individual housing. Measures to reduce noise are easier possible. The manufacturing costs are reduced.
Die gewünschte Abtriebsdrehzahl und -drehrichtung wird mit Hilfe der Regeleinheit eingestellt. Der Fahrmotor des Elektro-Wandlers kann dabei ausgangsseitig direkt mit einem Differentialgetriebe der Antriebsachse verbunden sein. Sofern erforderlich, kann jedoch auch ein Untersetzungsgetriebe zwischen dem Fahrmotor und dem Differen tialgetriebe angeordnet sein.The desired output speed and direction of rotation is determined using the control unit set. The traction motor of the electrical converter can also be used on the output side be connected to a differential gear of the drive axle. If necessary, can but also a reduction gear between the drive motor and the Differen tial gear be arranged.
Eine Weiterbildung der Erfindung sieht vor, dass der Elektro-Wandler und die Antriebs achse zu einem elektromechanischen Kompaktgetriebe zusammengefasst sind. Dieses Kompaktgetriebe wird als vormontierte Baueinheit am Fahrzeugrahmen befestigt bzw. kann einen Teil des Fahrzeugrahmens bilden.A further development of the invention provides that the electrical converter and the drive axis are combined to form an electromechanical compact gearbox. This compact transmission is a pre-assembled unit on the vehicle frame attached or can form part of the vehicle frame.
Bei räumlich getrennter Anordnung des Antriebsmotors ist dieser zweckmäßigerweise mittels einer Antriebswelle mit dem Kompaktgetriebe verbunden.If the drive motor is spatially separated, this is expedient connected to the compact transmission by means of a drive shaft.
In konsequenter Fortführung des Erfindungsgedankens ist es aber auch möglich, dass der Antriebsmotor mit dem Kompaktgetriebe verblockt ist. In diesem Fall ist der Antriebsstrang mit allen Komponenten (Antriebsmotor, Elektro-Wandler, Antriebs achse) zu einer vormontierten Baueinheit zusammengefasst.In a consistent continuation of the inventive concept, it is also possible that the drive motor is blocked with the compact transmission. In this case it is Drive train with all components (drive motor, electrical converter, drive axis) combined into a pre-assembled unit.
Sind die Platzverhältnisse im Bereich der Antriebsachse beengt, so kann eine andere zweckmäßige Ausgestaltung der Erfindung gewählt werden, bei der der Antriebsmotor mit dem Elektro-Wandler verblockt ist, der mittels einer Antriebswelle mit der Antriebs achse verbunden ist. In diesem Fall kann eine handelsübliche Antriebsachse ver wendet werden. If space is limited in the area of the drive axle, another can Expedient embodiment of the invention can be selected in which the drive motor is blocked with the electrical converter, which is connected to the drive by means of a drive shaft axis is connected. In this case, a commercially available drive axle can be used be applied.
Um die elektrischen Verbindungsleitungen kurz zu halten, ist es günstig, wenn die elektrische Regeleinheit im Bereich des Elektro-Wandlers angeordnet und/oder am Elektro-Wandler und/oder dem Kompaktgetriebe befestigt ist. Dadurch wird auch eine Vormontage dieser Baueinheit ermöglicht und somit die Endmontage des Antriebs strangs vereinfacht.In order to keep the electrical connection lines short, it is advantageous if the electrical control unit arranged in the area of the electrical converter and / or on Electric converter and / or the compact transmission is attached. This also makes one Pre-assembly of this unit enables and thus the final assembly of the drive strangs simplified.
Sofern eine Speichereinrichtung, insbesondere ein Akkumulator, vorgesehen ist, die an die Regeleinheit und den Elektro-Wandler angeschlossen ist, kann im Bremsbetrieb Energie gespeichert werden, beispielsweise als elektrische Energie eines Akkumula tors.If a storage device, in particular an accumulator, is provided, the on the control unit and the electrical converter can be connected in braking mode Energy can be stored, for example as electrical energy of an accumulator tors.
Besonders vorteilhaft ist die Verwendung des erfindungsgemäßen elektrischen Fahrantriebs in einem Flurförderzeug.The use of the electrical device according to the invention is particularly advantageous Travel drive in an industrial truck.
Weitere Vorteile und Einzelheiten der Erfindung werden anhand der in den schema tischen Figuren dargestellten Ausführungsbeispiele näher erläutert. Dabei zeigtFurther advantages and details of the invention are based on the in the scheme table figures illustrated embodiments explained in more detail. It shows
Fig. 1 eine erste Ausführungsform des erfindungsgemäßen elektrischen Fahrantriebs, Fig. 1 shows a first embodiment of the electrical travel drive according to the invention,
Fig. 2 eine zweite Ausführungsform des erfindungsgemäßen elektrischen Fahrantriebs und Fig. 2 shows a second embodiment of the electric travel drive according to the invention and
Fig. 3 eine dritte Ausführungsform des erfindungsgemäßen elektrischen Fahrantriebs. Fig. 3 shows a third embodiment of the electric travel drive according to the invention.
Der in Fig. 1 dargestellte elektrische Fahrantrieb weist einen Antriebsmotor 1 auf, der beispielsweise als Verbrennungsmotor ausgebildet ist. Selbstverständlich sind auch andere Ausführungen möglich, z. B. eine Gasturbine, ein Pressluftmotor usw.The electric travel drive shown in FIG. 1 has a drive motor 1 which is designed, for example, as an internal combustion engine. Of course, other designs are possible, e.g. B. a gas turbine, an air motor, etc.
Am anderen Ende des Antriebsstranges befindet sich eine Antriebsachse 2 mit zwei an den Achsenden angeordneten Treibrädern 3 und 4. Die Antriebsachse 2 enthält ein Differentialgetriebe 5 und kann darüber hinaus mit einem dem Differentialgetriebe 5 vorgeschalteten Untersetzungsgetriebe oder zwei dem Differentialgetriebe 5 nach geschalteten, radseitigen Untersetzungsgetrieben versehen sein. At the other end of the drive train there is a drive axle 2 with two drive wheels 3 and 4 arranged on the axle ends. The drive axle 2 contains a differential gear 5 and can also be provided with a reduction gear connected upstream of the differential gear 5 or two reduction gears connected downstream of the differential gear 5 .
Zwischen den Antriebsmotor 1 und die Abtriebsachse 2 sind ein mit dem Antriebsmotor 1 gekoppelter elektrischer Generator 6 und ein mit der Antriebsachse 2 gekoppelter elektrischer Fahrmotor 7 geschaltet. Der Generator 6 und der Fahrmotor 7 sind elek trisch miteinander verbunden und bilden einen elektrischen Drehmoment-Wandler, mit dessen Hilfe das vom Antriebsmotor 1 erzeugte Antriebsmoment variiert und an die Antriebsachse 2 weitergeleitet werden kann. Beide elektrische Maschinen können in Gleichstrom- oder in Wechselstrom- bzw. Drehstromtechnik ausgeführt sein.Between the driving motor 1 and the output shaft 2 is coupled to the drive motor 1 electric generator 6 and coupled to the drive shaft 2 driving electric motor 7 are connected. The generator 6 and the traction motor 7 are electrically connected to one another and form an electric torque converter, with the aid of which the drive torque generated by the drive motor 1 varies and can be passed on to the drive axle 2 . Both electrical machines can be implemented in direct current or in alternating current or three-phase technology.
Erfindungsgemäß sind der Generator 6 und der Fahrmotor 7 zu einem eine gemein same Baueinheit bildenden Elektro-Wandler 8 zusammengefasst. Es muß daher nur eine einzige Baugruppe, nämliche der Elektro-Wandler 8 montiert und in ein mit den elektrischen Fahrantrieb auszurüstendes Fahrzeug eingebaut werden. Bisher wurden zwei Baugruppen (Generator; Fahrmotor) getrennt voneinander montiert und im Fahr zeug befestigt. Zudem wird der Zeitaufwand für die Bauteilprüfung verringert, die vor dem Einbau in das Fahrzeug erfolgt.According to the invention, the generator 6 and the traction motor 7 are combined to form a common electrical converter 8 . It is therefore only necessary to mount a single assembly, namely the electric converter 8 , and to install it in a vehicle to be equipped with the electric travel drive. So far, two assemblies (generator; traction motor) have been assembled separately and attached to the vehicle. In addition, the time required for component testing, which is carried out before installation in the vehicle, is reduced.
Der Elektro-Wandler 8 kann beispielsweise dadurch hergestellt werden, daß der Generator 6 mit dem Fahrmotor 7 verschraubt wird. Günstiger ist es jedoch, wenn der Elektro-Wandler 8 ein für den Generator 6 und den Fahrmotor 7 gemeinsames Gehäuse 8a aufweist. Dadurch wird der Fertigungs- und Montageaufwand weiter reduziert. Ein gemeinsames Gehäuse 8a ist zudem steifer als zwei miteinander verbundene Einzelgehäuse. Schließlich vereinfachen sich auch Maßnahmen zur Geräuschdämpfung.The electrical converter 8 can be manufactured, for example, by screwing the generator 6 to the drive motor 7 . However, it is more favorable if the electrical converter 8 has a housing 8 a that is common to the generator 6 and the drive motor 7 . This further reduces manufacturing and assembly costs. A common housing 8 a is also stiffer than two interconnected individual housings. Finally, measures to reduce noise are also simplified.
Der Generator 6 des Elektro-Wandlers 8 ist im vorliegenden Ausführungsbeispiel mittels einer Antriebswelle 9 (beispielsweise eine Gelenkwelle) mit dem Antriebsmotor 1 gekoppelt. Die Koppelung des Fahrmotors 7 des Elektro-Wandlers 8 mit der Antriebsachse 2 kann ebenfalls mittels einer Welle erfolgen (nicht dargestellt).In the present exemplary embodiment, the generator 6 of the electrical converter 8 is coupled to the drive motor 1 by means of a drive shaft 9 (for example a cardan shaft). The driving motor 7 of the electric converter 8 can also be coupled to the drive axle 2 by means of a shaft (not shown).
Günstiger ist es jedoch, wenn - wie im vorliegenden Ausführungsbeispiel - der Elektro- Wandler 8 mit der Antriebsachse 2 zu einem elektromechanischen Kompaktgetriebe zusammengefasst ist. However, it is more favorable if — as in the present exemplary embodiment — the electrical converter 8 is combined with the drive axis 2 to form an electromechanical compact transmission.
Mittels einer an den Elektro-Wandler 8 angeschlossenen Regeleinheit 10 werden die Übersetzung, die Abtriebsdrehrichtung und das Verhältnis zwischen eingangsseitigem und ausgangsseitigem Drehmoment geregelt. An die Regeleinheit 10 und den Elektro- Wandler 8 ist eine Speichereinrichtung 11 angeschlossen, im vorliegenden Ausfüh rungsbeispiel ein Akkumulator. In der Speichereinrichtung 11 kann im Bremsbetrieb Energie gespeichert werden. Die Regeleinrichtung 10 ist bevorzugt unmittelbar im Bereich des Elektro-Wandlers 8 angeordnet oder an diesem befestigt, dadurch können die Verbindungskabel kurz gehalten werden und es ergeben sich Montagevorteile.By means of a control unit 10 connected to the electrical converter 8 , the translation, the output rotation direction and the ratio between the input-side and output-side torque are regulated. A storage device 11 is connected to the control unit 10 and the electrical converter 8 , in the present exemplary embodiment an accumulator. Energy can be stored in the storage device 11 during braking operation. The control device 10 is preferably arranged directly in the area of the electrical converter 8 or fastened to it, as a result of which the connecting cables can be kept short and assembly advantages result.
Das Ausführungsbeispiel nach Fig. 2 unterscheidet sich von dem Ausführungsbeispiel nach Fig. 1 dadurch, dass der Antriebsmotor 1 mit dem aus dem Elektro-Wandler 8 und der Antriebsachse 2 gebildeten Kompaktgetriebe verblockt ist. Dabei wird die Antriebswelle 9 eingespart.The exemplary embodiment according to FIG. 2 differs from the exemplary embodiment according to FIG. 1 in that the drive motor 1 is interlocked with the compact transmission formed from the electrical converter 8 and the drive axis 2 . The drive shaft 9 is saved.
Eine weitere Ausführungsform der Erfindung zeigt Fig. 3. Dort ist der Antriebsmotor 1 mit dem Elektro-Wandler 8 zu einer Baueinheit zusammengefasst, während die Antriebsachse 2 räumlich getrennt angeordnet und mittels einer Antriebswelle 12 mit dem Ausgang des Elektro-Wandlers verbunden ist.A further embodiment of the invention is shown in FIG. 3. There the drive motor 1 is combined with the electrical converter 8 to form a structural unit, while the drive axis 2 is arranged spatially separated and connected to the output of the electrical converter by means of a drive shaft 12 .
