Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Vermeiden eines Schadens eines Lagers mindestens einer Welle eines Reichweitenverlängerers eines Elektrofahrzeuges. The present invention relates to a method and a device for avoiding damage to a bearing of at least one shaft of a range extender of an electric vehicle.
Stand der Technik State of the art
Um die Reichweite von Elektrofahrzeugen zu erhöhen, werden seit einiger Zeit sogenannte Reichweitenverlängerer, auch als Range Extender bezeichnet, eingesetzt. Diese umfassen einen Verbrennungsmotor mit nachgeschaltetem Generator, der im Bedarfsfall die Batterie lädt, welche die Energie für den elektrischen Antrieb liefert. To increase the range of electric vehicles, so-called range extenders, also known as range extenders, are used for some time. These include an internal combustion engine with a downstream generator which, if necessary, charges the battery which supplies the power for the electric drive.
Im Gegensatz zu Verbrennungsmotoren, welche auch als Antriebsaggregat für das Fahrzeug genutzt werden, können die Verbrennungsmotoren für Reichweitenverlängerer auf deutlich geringere Leistungen ausgelegt werden und stets in einem optimalen Betriebspunkt betrieben werden. In contrast to internal combustion engines, which are also used as a drive unit for the vehicle, the internal combustion engines for range extenders can be designed for significantly lower outputs and can always be operated at an optimum operating point.

Aus der
Über einen elektrischen Zusatzmotor, welcher ebenfalls mit dem Planetengetriebe verbunden ist, kann bei dem dort beschriebenen Kraftfahrzeug die Drehzahl des Kompressors in einem günstigen Drehzahlbereich gehalten werden. Bei stehendem Kraftfahrzeug und ausgeschalteter Verbrennungskraftmaschine wird der Kompressor elektrisch von dem Zusatzmotor angetrieben. About an additional electric motor, which is also connected to the planetary gear, the speed of the compressor can be kept in a favorable speed range in the described motor vehicle. When the vehicle is stationary and the internal combustion engine is switched off, the compressor is driven electrically by the auxiliary engine.
Offenbarung der Erfindung Disclosure of the invention
Die vorliegende Erfindung schafft ein Verfahren zum Vermeiden eines Schadens eines Lagers mindestens einer Welle eines Reichweitenverlängerers eines Elektrofahrzeuges mit den Merkmalen des Patentanspruchs 1. The present invention provides a method for avoiding damage to a bearing of at least one shaft of a range extender of an electric vehicle having the features of patent claim 1.
Demgemäß ist ein Verfahren mit folgenden Verfahrensschritten vorgesehen: Erzeugen eines Drehmomentes mit Hilfe einer elektrischen Motorgeneratoreinrichtung des Reichweitenverlängerers während eines Ruhezustands des Reichweitenverlängerers; und Drehen der mindestens einen Welle des Reichweitenverlängerers mittels des erzeugten Drehmomentes. Accordingly, a method is provided with the following method steps: generating a torque with the aid of an electric motor-generator device of the range extender during a rest state of the range extender; and rotating the at least one shaft of the range extender by means of the generated torque.
Die Erfindung schafft außerdem eine Vorrichtung zum Vermeiden eines Schadens eines Lagers mindestens einer Welle eines Reichweitenverlängerers eines Elektrofahrzeuges gemäß Patentanspruch 8. The invention also provides a device for avoiding damage to a bearing of at least one shaft of a range extender of an electric vehicle according to claim 8.
Demgemäß ist eine Vorrichtung zum Vermeiden eines Schadens eines Lagers mindestens einer Welle eines Reichweitenverlängerers eines Elektrofahrzeuges vorgesehen. Accordingly, an apparatus for avoiding damage to a bearing of at least one shaft of a range extender of an electric vehicle is provided.
Die Vorrichtung umfasst eine Sensoreinrichtung, welche dazu ausgebildet ist, einen Ruhezustand des Reichweitenverlängerers und mindestens eine Drehwinkelstellung der mindestens einen Welle des Reichweitenverlängerers zu erfassen; und eine Steuereinrichtung, welche dazu ausgebildet ist, ein auf die mindestens eine Welle wirkendes Drehmoment mit Hilfe von einer elektrischen Motorgeneratoreinrichtung des Reichweitenverlängerers während eines Ruhezustandes des Reichweitenverlängerers zu erzeugen und dadurch einen Drehwinkel der mindestens einen Welle des Reichweitenverlängerers mittels des erzeugten Drehmomentes zu verstellen. The device comprises a sensor device which is designed to detect an idle state of the range extender and at least one rotational angle position of the at least one shaft of the range extender; and a control device configured to generate a torque acting on the at least one shaft by means of an electric motor generator device of the range extender during a rest condition of the range extender and thereby adjust a rotational angle of the at least one shaft of the range extender by means of the generated torque.
Vorteile der Erfindung Advantages of the invention
Die Idee der Erfindung liegt darin, den einseitigen Verschleiß der Lager der Wellen des Reichweitenverlängerers zu reduzieren. Wird das Elektrofahrzeug nur für Kurzstrecken eingesetzt und regelmäßig geladen, so wird der Reichweitenverlängerer sehr selten in Betrieb sein. Die dadurch beanspruchten Lager der Wellen, sowohl die der Brennkraftmaschine als auch die der elektrischen Motorgeneratoreinrichtung des Reichweitenverlängerers werden vorteilhaft durch eine vorbestimmte Drehung der gelagerten Wellen gleichmäßig abgenutzt. The idea of the invention is to reduce the unilateral wear of the bearings of the shaft of the range extender. If the electric vehicle is used only for short distances and regularly charged, the range extender will be very rarely in operation. The thus claimed bearings of the waves, both the internal combustion engine and the electric motor generator means of the range extender are advantageously uniformly worn by a predetermined rotation of the stored waves.
Die Kontaktstellen der Lager und der in den Lagern gelagerten Wellen werden verschoben und mechanische Belastungen werden somit auf die gesamte Oberfläche der Wellen verteilt. The contact points of the bearings and the shafts stored in the bearings are shifted and mechanical stresses are thus distributed over the entire surface of the shafts.
Vorteilhafte Ausführungsformen und Weiterbildungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung unter Bezugnahme auf die Figuren. Advantageous embodiments and further developments emerge from the dependent claims and from the description with reference to the figures.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass als die mindestens eine Welle des Reichweitenverlängerers eine Kurbelwelle einer Brennkraftmaschine gedreht wird. Dadurch kann vorteilhaft der einseitige Verschleiß der Lager der Kurbelwellen der Brennkraftmaschine des Reichweitenverlängerers reduziert werden. According to one embodiment of the invention, it is provided that, as the at least one shaft of the range extender, a crankshaft of an internal combustion engine is rotated. As a result, the one-sided wear of the bearings of the crankshafts of the internal combustion engine of the range extender can advantageously be reduced.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass die Kurbelwelle gegen einen Kompressionsdruck der Kurbelwelle gedreht wird und eine Drehrichtung der Kurbelwelle geändert wird, falls der Kompressionsdruck der Kurbelwelle ein vorbestimmtes Drehmoment übersteigt. Dadurch kann vorteilhaft der Energieverbrauch der Vorrichtung und damit des Elektrofahrzeuges reduziert werden. According to one embodiment of the invention, it is provided that the crankshaft is rotated against a compression pressure of the crankshaft and a direction of rotation of the crankshaft is changed if the compression pressure of the crankshaft exceeds a predetermined torque. As a result, the energy consumption of the device and thus of the electric vehicle can advantageously be reduced.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass als die mindestens eine Welle des Reichweitenverlängerers eine Antriebswelle der elektrischen Generatormotoreinrichtung gedreht wird. Dies erlaubt vorteilhaft, die Antriebswelle der elektrischen Generatormotoreinrichtung vor einem Festsetzen der in den Antriebswellenlagern gelagerten Antriebswelle zu schützen. According to one embodiment of the invention, it is provided that, as the at least one shaft of the range extender, a drive shaft of the electric generator motor device is rotated. This advantageously allows to protect the drive shaft of the electric generator motor device from settling the drive shaft mounted in the drive shaft bearings.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass das Drehen der mindestens einen Welle des Reichweitenverlängerers schrittweise innerhalb vorbestimmter Zeitabstände vorgenommen wird. Dadurch kann vorteilhaft der Schutz der Lager auch über einen im Vergleich zu den typischen Einsatzzeiten des Elektrofahrzeuges längeren Zeitraum sichergestellt werden. According to one embodiment of the invention, it is provided that the rotation of the at least one shaft of the range extender is performed stepwise within predetermined time intervals. As a result, the protection of the bearings can advantageously also be ensured by means of a longer period of time compared to the typical operating times of the electric vehicle.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass die vorbestimmten Zeitabstände an einen elektrischen Leistungsbedarf des Elektrofahrzeuges angepasst werden. Dies erlaubt vorteilhaft, dass die zum Antrieb zu Verfügung stehende elektrische Leistung des Elektrofahrzeuges nicht beeinträchtigt wird. According to one embodiment of the invention, it is provided that the predetermined time intervals are adapted to an electrical power requirement of the electric vehicle. This advantageously allows the electric power available to the drive of the electric vehicle not to be impaired.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass das Drehen der mindestens einen Welle des Reichweitenverlängerers weniger als eine Volldrehung der mindestens einen Welle umfasst. Dies erlaubt einen energiesparenden Einsatz der Vorrichtung zum Vermeiden eines Schadens eines Lagers mindestens einer Welle eines Reichweitenverlängerers eines Elektrofahrzeuges. According to one embodiment of the invention, it is provided that the rotation of the at least one shaft of the range extender comprises less than one complete rotation of the at least one shaft. This allows an energy-saving use of the device for avoiding damage to a bearing of at least one shaft of a range extender of an electric vehicle.
