Description

Die Erfindung betrifft ein von einem Elektromotor ange­ triebenes, einen Batterieraum mit Batterien aufweisendes Kraftfahrzeug, welches zusätzlich mit einem Brennkraft­ motor ausgestattet ist.The invention relates to an electric motor driven, having a battery room with batteries Motor vehicle, which also has an internal combustion engine motor is equipped.

Die Entwicklung von elektromotorisch angetriebenen Kraft­ fahrzeugen wird derzeit mit großem finanziellen Aufwand gefördert, weil solche Fahrzeuge im Vergleich zu brenn­ kraftangetriebenen Kraftfahrzeugen wesentlich umwelt­ freundlicher sind. Nachteilig bei den ausschließlich elektrisch angetriebenen Kraftfahrzeugen ist, daß sich ihre Batterien relativ rasch erschöpfen, so daß sie sich bislang überwiegend nur für den Stadtverkehr eignen.The development of electric motor power vehicles is currently with great financial expense promoted because such vehicles burn compared to power-driven motor vehicles significantly environmental are friendlier. A disadvantage of the exclusively electrically powered motor vehicles is that itself exhaust their batteries relatively quickly, so that they become exhausted So far, they are mainly only suitable for city traffic.

Zur Erhöhung der Reichweite von elektromotorisch ange­ triebenen Kraftfahrzeugen ist es bekannt, diese zusätz­ lich mit einem Antrieb durch einen Brennkraftmotor zu versehen. Das ermöglicht es, bei Überlandfahrten den Brennkraftmotor als Antrieb und bei Fahrten in der Innen­ stadt, wo es auf die Vermeidung schädlicher Abgase ganz besonders ankommt, den Elektromotor zu benutzen. Weiter­ hin kann bei einem solchen Hybridantrieb bei Überland­ fahrten mittels des Brennkraftmotors zusätzlich zum Fahr­ zeugantrieb ein Generator zum Aufladen der Batterien angetrieben werden.To increase the range of electric motors driven motor vehicles, it is known to add this Lich with a drive by an internal combustion engine Mistake. This makes it possible to travel overland Internal combustion engine as drive and when traveling inside city where it is all about avoiding harmful emissions especially arrives to use the electric motor. Next Such a hybrid drive can be used in overland areas traveled by means of the internal combustion engine in addition to driving a generator for charging the batteries are driven.

Ungünstig bei solchen Kraftfahrzeugen ist es, daß sie bei Betrieb mit Brennkraftmotor ebenso nachteilig für die Umwelt sind wie übliche Kraftfahrzeuge mit Brenn­ kraftmotor. Weiterhin ist wegen der beiden separaten Antriebe ein solches Kraftfahrzeug relativ teuer herzu­ stellen. It is unfavorable in such motor vehicles that they when operated with an internal combustion engine also disadvantageous for the environment is like conventional motor vehicles with combustion motor. Furthermore, because of the two separate Drives such a motor vehicle relatively expensive put.  

Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahr­ zeug der eingangs genannten Art zu entwickeln, welches die Vorteile eines elektromotorisch angetriebenen Kraft­ fahrzeugs mit denen eines Kraftfahrzeugs mit Brennkraft­ motor im möglichst hohen Maße auf sich vereint.The invention has for its object a motor vehicle to develop stuff of the type mentioned at the beginning the advantages of an electric motor-powered force vehicle with those of a motor vehicle with internal combustion engine combined as much as possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Brennkraftmotor ausschließlich zum Antrieb eines zum Laden der Batterien vorgesehenen Batterieladegenerators ausgebildet ist.This object is achieved in that the internal combustion engine only to drive one to Charging the batteries provided battery charger is trained.

Bei einem solchen Kraftfahrzeug kann der Brennkraftmotor wesentlich kleiner bemessen sein als bei einem vergleich­ baren Kraftfahrzeug mit Antrieb ausschließlich durch einen Brennkraftmotor oder mit Hybridantrieb, da die Energie für Leistungsspitzen den Batterien entnommen wird und der Brennkraftmotor deshalb mit einer zum Auf­ laden der Batterien ausreichenden, relativ geringen Grundlast arbeiten kann. Das gleichmäßige Arbeiten der Brennkraftmaschine ermöglicht es, daß diese stets in einem für ihren Wirkungsgrad, ihre Haltbarkeit und den Schadstoffgehalt des Abgases optimalen Drehzahlbereich laufen kann, so daß auch ohne Katalysator ausreichend sauberes Abgas zu erzielen ist. Ein weiterer Vorteil der Verwendung des Brennkraftmotors ausschließlich zum An­ trieb des Generators liegt darin, daß das Kraftfahrzeug kein Schaltgetriebe benötigt, so daß es insgesamt sehr kostengünstig herstellbar ist.In such a motor vehicle, the internal combustion engine be much smaller than a comparison ble motor vehicle with drive only through an internal combustion engine or with hybrid drive, because the Energy for power peaks taken from the batteries and therefore the internal combustion engine with one to open charge the batteries sufficiently, relatively low Base load can work. The even work of the Internal combustion engine enables them to always be in one for their efficiency, their durability and the Pollutant content of the exhaust gas optimal speed range can run so that even without a catalyst sufficient clean exhaust gas can be achieved. Another advantage of Use of the internal combustion engine only for on drive of the generator is that the motor vehicle No manual gearbox needed, making it very much overall is inexpensive to manufacture.

Eine ganz besonders vorteilhafte Weiterbildung der Erfin­ dung besteht darin, daß der Batterieladegenerator und der Brennkraftmotor in einem lösbar mit der Fahrzeug­ karosserie verbindbaren, separaten Ladeaggregatteil ange­ ordnet sind. Diese Ausbildung ermöglicht es, das Kraft­ fahrzeug auch ohne Mitführen des Brennkraftmotors und des Batterieladegenerators beispielsweise für die täg­ liche Fahrt zum Arbeitsplatz zu benutzen, wodurch das Kraftfahrzeug dann insgesamt leichter wird, so daß sich sein Energieverbrauch verringert und höhere Beschleuni­ gungen zu erzielen sind.A particularly advantageous further training of the Erfin tion is that the battery charging generator and the internal combustion engine in a detachable manner with the vehicle body connectable, separate charger part are arranged. This training enables the force vehicle even without carrying the internal combustion engine and the battery charging generator, for example for the day  to use the journey to work, which means that Motor vehicle then becomes lighter overall, so that its energy consumption is reduced and accelerations are higher are to be achieved.

Das Ladeaggregatteil kann als ein an das Kraftfahrzeug anzukuppelnder Anhänger ausgebildet sein. Eine solche Ausführungsform ist sehr kostengünstig und erfordert keinerlei Umgestaltungen an einem üblichen, elektromo­ torisch angetriebenen Kraftfahrzeug. Sie bietet zusätz­ lich den Vorteil, daß ein solcher Anhänger die Ladekapa­ zität des Kraftfahrzeugs zu erhöhen vermag.The charging unit part can be attached to the motor vehicle be coupled trailer trained. Such Embodiment is very inexpensive and requires no changes to a conventional, electromo toric motor vehicle. It offers additional Lich the advantage that such a trailer the Ladekapa ability of the motor vehicle to increase.

Eine andere, sehr vorteilhafte Ausgestaltung der Erfin­ dung besteht darin, daß das Ladeaggregatteil ein am Fahr­ zeugheck zu befestigender rucksackartiger Aufsatz ist. Durch einen solchen Aufsatz lassen sich die Nachteile eines Anhängerbetriebes, insbesondere Schwierigkeiten beim Rangieren und Einparken und schlechtere Fahreigen­ schaften bei hohen Geschwindigkeiten, vermeiden.Another, very advantageous embodiment of the Erfin manure is that the charger part on a driving hatchback to attach backpack-like attachment. With such an essay, the disadvantages can be overcome a trailer company, especially difficulties when maneuvering and parking and poor driving skills at high speeds, avoid.

Besonders vorteilhaft ist es, wenn das Ladeaggregatteil aus einem von oben her auf den Kofferraum des Fahrzeug­ hecks aufsitzenden, im wesentlichen horizontalen, einen zusätzlichen Laderaum bildenden Bereich und einem den Verbrennungsmotor und das Ladeaggregat aufnehmenden, von hinten her gegen den Kofferraum des Fahrzeughecks anlie­ genden, vertikalen Bereich gebildet ist. Durch ein sol­ ches Ladeaggregatteil läßt sich die Ladekapazität des Kraftfahrzeugs vergrößern, was besonders vorteilhaft ist, weil das Ladeaggregatteil immer dann benötigt wird, wenn größere Fahrstrecken zurückgelegt werden sollen und gerade dann auch üblicherweise mehr Gepäck mitgeführt werden muß. It when the loading unit part is particularly advantageous from above onto the trunk of the vehicle rear-sitting, essentially horizontal, one additional cargo space and an area Internal combustion engine and the charger, from against the trunk of the rear of the vehicle ing vertical area is formed. Through a sol Ches loading unit part, the loading capacity of the Motor vehicle enlarge, which is particularly advantageous is because the charger part is always needed if larger distances are to be covered and just then usually carry more luggage must become.  

Vorteilhaft kann es auch sein, wenn der horizontale Be­ reich als Pritsche ausgebildet ist. Hierdurch kann bei­ spielsweise ein viersitziges Kabriolett in ein Pick-up- Fahrzeug umgewandelt werden, dessen Ladefläche durch entsprechende Bemessung des horizontalen Bereiches des Ladeaggregatteils bis zu den Vordersitzen reichen kann.It can also be advantageous if the horizontal loading is richly trained as a flatbed. This can help for example, a four-seater convertible in a pick-up Vehicle can be converted, the loading area through appropriate dimensioning of the horizontal area of the Loading unit part can extend to the front seats.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist in der Zeichnung ein Kraftfahrzeug schematisch in Seitenansicht mit seinen für die Erfindung wesentlichen Einbauteilen dargestellt und wird nachfolgend beschrieben.The invention permits numerous embodiments. To further clarification of their basic principle is in the Drawing a motor vehicle schematically in side view with its built-in parts essential for the invention shown and will be described below.
