Description
Die vorliegende Erfindung betrifft einen Elektroantrieb für ein Fahrzeug gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art. The present invention relates to an electric drive for a vehicle according to the closer defined in the preamble of
Aus der Fahrzeugtechnik sind zweigängige Getriebevarianten für Fahrzeugelektroantriebe bekannt. Die Elektroantriebe umfassen eine elektrische Maschine, die mit dem Getriebeeingang eines Planetengetriebes koppelbar ist, wobei dem Getriebeausgang als Abtrieb ein Differenzialgetriebe zugeordnet ist. Zum Schalten der beiden Gangstufen sind nasslaufende Reibschaltelemente vorgesehen. Bei eingelegtem Gang werden bei dem bekannten Elektroantrieb aufgrund auftretender Schleppmomente an den Reibschaltelementen der Gesamtwirkungsgrad verringert. Speziell der Antrieb im Hauptgeschwindigkeitsbereich, nämlich im ersten Gang im Stadt- und stadtnahen Betriebsbereich führt aufgrund des wälzenden Planetengetriebes im ersten Gang zu einem zusätzlichen Wirkungsgradnachteil. From the vehicle technology zweigängige transmission variants for vehicle electric drives are known. The electric drives comprise an electric machine which can be coupled to the transmission input of a planetary gear, wherein the transmission output is assigned as output a differential gear. To switch the two gear ratios wet running Reibschaltelemente are provided. When engaged, the overall efficiency is reduced in the known electric drive due to drag torque occurring at the Reibschaltelementen. Specifically, the drive in the main speed range, namely in first gear in the city and city-related operating range leads due to the rolling planetary gear in first gear to an additional efficiency disadvantage.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Elektroantrieb der eingangs beschriebenen Gattung vorzuschlagen, der hinsichtlich seines Gesamtwirkungsgrades optimiert ist. The present invention is based on the object to propose an electric drive of the type described above, which is optimized in terms of its overall efficiency.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst, wobei sich vorteilhafte Ausgestaltungen aus den Unteransprüchen, der Beschreibung und den Zeichnungen ergeben. This object is achieved by the features of
Bei dem erfindungsgemäßen Elektroantrieb ist zumindest als Antrieb eine elektrische Maschine vorgesehen, die mit einem Zweiganggetriebe als Planetengetriebe oder dergleichen koppelbar ist, wobei das Planetengetriebe zwei Schaltelemente zum Realisieren der Übersetzungsstufen umfasst. Dem Planetengetriebe ist ein Untersetzungsgetriebe als Abtrieb nachgeschaltet. Das Planetengetriebe ist derart mit An- und Abtrieb gekoppelt, dass der erste Gang verblockt betrieben wird, indem zwei Elemente des Planetengetriebes miteinander verbunden sind, so dass auf diese Weise der erste Gang, der den Hauptfahrbereich des Elektroantriebes entspricht als Direktgang ausgeführt ist und unnötige Wälzverluste verhindert werden. In the electric drive according to the invention, an electric machine is provided at least as a drive, which can be coupled with a two-speed transmission as a planetary gear or the like, wherein the planetary gear comprises two switching elements for realizing the gear ratios. The planetary gear is followed by a reduction gear as an output. The planetary gear is so coupled with input and output that the first gear is operated locked by two elements of the planetary gear are connected to each other, so that in this way the first gear, which corresponds to the main driving range of the electric drive is designed as a direct gear and unnecessary rolling losses be prevented.
Daraus ergibt sich für den Hauptfahranteil des Elektroantriebes ein optimaler Wirkungsgrad. Der Wirkungsgrad wird weiter verbessert, indem als Schaltelemente trocken laufende Reibschaltelement eingesetzt werden, so dass bei den offen laufenden Schaltelementen keine Schleppverluste und möglichst geringe Vibration auftreten. This results in an optimal efficiency for the main driving portion of the electric drive. The efficiency is further improved by using dry-running friction switching elements as switching elements, so that no drag losses and the lowest possible vibration occur in the open-running switching elements.
Im Rahmen einer weiteren besonders vorteilhaften Ausführung der Erfindung kann vorgesehen sein, dass die elektrische Maschine als Läufer einen Außenläufer oder Innenläufer aufweist, wodurch sich der Bauraumbedarf je nach Anwendungsbereich optimieren lässt, so dass der vorgeschlagene Elektroantrieb möglich schmal gebaut werden kann, um auch für den Frontquerantrieb geeignet zu sein. Der vorgeschlagene Elektroantrieb eignet sich nicht nur für elektrische Fahrzeugantriebe mit Frontquer-, Frontlängs- und Heckquereinbau. Vielmehr ist auch die Verwendung als Achsantrieb möglich, da die elektrische Maschine im Falle des verbrennungsmotorisches Antriebes über die andere Achse durch Öffnen der beiden Schaltelemente auf einfachste Weise abgekoppelt werden kann und dadurch keine Nulllastverluste der elektrischen Maschine auftreten. Im Falle eines Frontquereinbaus ergibt sich die kürzeste Breite des Antriebes, wenn das Planetengetriebe und der Ölsumpf innerhalb der elektrischen Maschine untergebracht werden. In the context of a further particularly advantageous embodiment of the invention can be provided that the electrical machine as a runner has an external rotor or internal rotor, which can optimize the space requirements depending on the application, so that the proposed electric drive can be made narrow narrow to even for the Front transverse drive to be suitable. The proposed electric drive is not only suitable for electric vehicle drives with front transverse, front longitudinal and rear transverse installation. Rather, the use as a final drive is possible because the electric machine in the case of the internal combustion engine drive via the other axis can be disconnected by opening the two switching elements in the simplest way and thus no zero load losses of the electric machine occur. In the case of a front transverse installation, the shortest width of the drive results when the planetary gear and the oil sump are housed within the electric machine.
Alternative konstruktive Ausführungen des Planetengetriebes können dadurch realisiert werden, dass dieses als Minus-Planetenradsatz oder auch als Plus-Planetenradsatz ausgeführt ist. Als Schaltelemente werden vorzugsweise trockene normally, closed Schaltelemente mit selbsthemmenden Aktuatoren vorgesehen. Durch die selbsthemmende Wirkung kann eine Ölpumpe mit kontinuierlicher Leistungsaufnahme entfallen. Alternative design versions of the planetary gear can be realized that this is designed as a minus planetary gear or as a plus planetary gear. As switching elements preferably dry normally, closed switching elements are provided with self-locking actuators. The self-locking effect eliminates the need for an oil pump with continuous power consumption.
Der Abtrieb wird vorzugsweise durch ein zweistufiges Untersetzungsgetriebe oder dergleichen realisiert, wobei mindestens eine Stufe eine Stirnradstufe ist, in deren Abtriebsrad ein Differenzialgetriebe untergebracht werden kann. The output is preferably realized by a two-stage reduction gear or the like, wherein at least one stage is a spur gear, in the output gear, a differential gear can be accommodated.
Nachfolgend wird die vorliegende Erfindung anhand der Zeichnungen weiter erläutert. Es zeigen: Hereinafter, the present invention will be further explained with reference to the drawings. Show it:

Aus der Zugkraftkennlinie 1. Gang ist ersichtlich, dass das Fahrzeug mit maximaler Zugkraft bis etwa 50 km/h beschleunigt werden kann. Danach fällt die Zugkraftkennlinie bis zu einer Gangendgeschwindigkeit von etwa 100 km/h ab. Aus der Zugkraftkennlinie 2. Gang ist ersichtlich, dass das Fahrzeug mit maximaler Zugkraft bis etwa 75 km/h beschleunigt werden kann. Danach fällt die Zugkraftkennlinie bis zu einer Gangendgeschwindigkeit von etwa 150 km/h ab. Aus den dargestellten Zugkraftkennlinien ergeben sich der angedeutete Wirkungsgradbestbereich 1. Gang und der angedeutete Wirkungsgradbestbereich 2. Gang. Es ist ersichtlich, dass sich der Geschwindigkeitsbereich zwischen 30 und 100 km/h mit optimalem Wirkungsgrad abdecken lässt, da die etwa parabelförmig angedeuteten Wirkungsgradbestbereiche der beiden Gänge möglichst nah aneinander liegen und sogar Überschneidungsbereiche aufweisen. Demzufolge kann auch nach dem Umschalten von dem ersten in den zweiten Gang mit optimalem Wirkungsgradbereich weitergefahren werden. It can be seen from the 1st power draft characteristic that the vehicle can be accelerated with maximum tractive force up to approximately 50 km / h. Thereafter, the traction characteristic drops to a final gear speed of about 100 km / h. It can be seen from the traction characteristic curve 2nd gear that the vehicle can be accelerated with maximum tractive force up to about 75 km / h. Thereafter, the traction characteristic drops to a final speed of about 150 km / h. From the illustrated traction characteristics, the indicated efficiency range 1st gear and the indicated efficiency range 2nd gear result. It can be seen that the speed range between 30 and 100 km / h can be covered with optimum efficiency, since the approximately parabolic indicated Bestbestbereiche the two courses are as close as possible to each other and even have overlapping areas. Consequently, it is possible to proceed even after switching from the first to the second gear with optimum efficiency range.
