Description

Die Erfindung bezieht sich auf ein Kraftfahrzeug zum wahlweisen Antrieb durch einen Verbrennungsmotor mit lösbarer Kupplung zu einem Wechselgetriebe oder durch eine ebenfalls über das Wechselgetriebe des Verbrennungsmotors arbeitende und aus einer Batterie speisbare elektrische Maschine, wobei die gleiche elektrische Maschine bei Antrieb des Kraftfahrzeugs durch den Verbrennungsmotor als Ladegenerator arbeiten kann.The invention relates to a motor vehicle for optional propulsion by an internal combustion engine with a releasable coupling to a change gear or by a likewise via the change gear of the internal combustion engine working electrical machine that can be fed from a battery, wherein the same electric machine when the motor vehicle is driven by the internal combustion engine as Charge generator can work.

Eine derartige Anordnung ist aus der US-Patentschrift 1 323 500 bekannt. Der Elektromotor ist dabei, koaxial mit der Hauptwelle des Verbrennungsmotors, zwischen diesem letzteren und einem nachgeschalteten Getriebe ebenfalls koaxial zu dessen Eingangswelle angeordnet. Dieser Elektromotor muß also für eine Bewegung des Fahrzeugs überhaupt ebenso große Drehmomente aufbringen wie der Verbrennungsmotor, was ihn groß und schwer macht und auch die Batterie dementsprechend stärker belastet, da der Wirkungsgrad des Elektromotors, auf die gleiche Leistung gesehen, stark zurückgeht. Man benötigt bei dieser bekannten Anordnung schon ein erhebliches Batteriegewicht, damit überhaupt gefahren werden kann, da große Anzugsströme gebraucht werden. Such an arrangement is known from US Pat. No. 1,323,500. The electric motor is there coaxial with the main shaft of the internal combustion engine, between the latter and a downstream one Gearbox also arranged coaxially to its input shaft. This electric motor must in other words, to move the vehicle, generate the same amount of torque as the internal combustion engine, what makes it big and heavy and also puts a higher load on the battery, because the efficiency of the electric motor, seen on the same power, drops sharply. You need with this known arrangement already a considerable battery weight, so driven at all can be, since large inrush currents are needed.

Andererseits ist es bekannt, ein im Normalbetrieb durch einen Verbrennungsmotor angetriebenes Fahrzeug über kurze Strecken mit dem elektrischen Anlasser hilfsweise zu bewegen, wobei allerdings der Verbrennungsmotor mitgedreht werden muß, was wiederum eine erhebliche zusätzliche Belastung für die Batterie ist.On the other hand, it is known to use a vehicle driven by an internal combustion engine during normal operation to move over short distances with the electric starter as an alternative, although the Combustion engine must be rotated, which in turn is a considerable additional burden for the battery is.

Ausgehend von der recht aufwendigen bekannten gemischt-brennkraft-elektrischen Antriebsanordnung nach der US-PS 1 323 500 soll nach der -der Erfindung zugrunde.:, liegenden Aufgabe eihj.'Antrieb geschaffen werden, der keinen wesentlich größerenBased on the very complex known mixed-combustion-electric drive arrangement According to US Pat. No. 1,323,500, the invention is based on the object of the invention not a much bigger one

ίο Aufwand für die Elektroanlage bedingt als die bekannten Anordnungen für das Fahren mit dem Anlasser, jedoch gestattet, eine wesentlich größere Fahrstrecke, bei u. U. höherer Geschwindigkeit, zu durchfahren. ίο More effort for the electrical system than the known ones Arrangements for driving with the starter, but allowing a much longer driving distance, at possibly higher speed to drive through.

Erfindungsgemäß wird dies dadurch erreicht, daß als elektrische Maschine eine an sich bekannte Anlaßlichtmaschine mit einem deren Drehmoment beim Anlassen vervielfachenden und bei Übergang zum Ladebetrieb selbsttätig auf eine kleinere Unterset-According to the invention, this is achieved in that a known starting generator is used as the electrical machine with a torque that multiplies when starting and when transitioning to Loading operation automatically on a smaller subset

ao zung umschaltenden Hilfs-Untersetzungsgetriebe angewendet ist, wobei die Ausgangswelle des Hilfs-Untersetzungsgetriebes direkt mit der Eingangswelle des Wechselgetriebes gekuppelt ist.ao application switching auxiliary reduction gear is, the output shaft of the auxiliary reduction gear directly to the input shaft of the Gearbox is coupled.

Bei dieser erfindungsgemäßen Lösung wird gegenas über den bekannten Anordnungen nicht nur das Batteriegewicht im Vergleich zur Fahrstrecke relativ klein, sondern die Erfindung ist ohne fundamentalen Eingriff in das Konzept bestehender Kraftfahrzeuge realisierbar und der heute akute Wunsch, eine beschränkte Fahrleistung mit relativ kleiner Batterie mit einem konventionellen Fahrzeug zu erreichen, erfüllbar. In this solution according to the invention, not only is the battery weight compared to the known arrangements Relatively small compared to the driving distance, but the invention is without fundamental Intervention in the concept of existing motor vehicles is feasible and today's acute desire, a limited one Achieving driving performance with a relatively small battery with a conventional vehicle is achievable.

Die US-PS 1 131402 zeigt zwar auch schon die Ankoppelung des elektrischen Anlassers an die Eingangswelle des Wechselgetriebes, jedoch wird die Erfindung gerade in der Kombination mit dem selbsttätig umschaltenden Hilfs-Untersetzungsgetriebe gesehen, was einen besonders wirtschaftlichen elektrischen Hilfsantrieb für ein brennkraft-maschinengetriebenes Fahrzeug ermöglicht.The US-PS 1 131402 already shows the coupling of the electric starter to the input shaft of the gearbox, however, the invention is automatic in combination with the switching auxiliary reduction gear seen what a particularly economical electrical Auxiliary drive for a combustion engine-driven vehicle allows.

In Ausgestaltung der Erfindung wird vorgeschlagen, daß das Untersetzungshilfsgetriebe beim Drehkraftwechsel durch Überholungskupplungen selbsttätig schaltbar ist. Überholkupplungen sind an sich ebenfalls bekannt. Jedoch erzielt man mit der Erfindung bei normaler Auslegung für Schrittbetrieb oder langsame Fahrgeschwindigkeit eine bedeutend größere Fahrstrecke.
Die weitere Ausgestaltung der Erfindung ist gekennzeichnet durch eine derartige Bemessung der elektrischen Einrichtung, daß die für den Stadtverkehr nötige Geschwindigkeit bei im täglichen Betrieb ausreichender Fahrstrecke mit einer Batterieladung erzielbar ist.In an embodiment of the invention it is proposed that the auxiliary reduction gear can be switched automatically by overrunning clutches when the torque is changed. Overrunning clutches are also known per se. However, with the invention, with a normal design for step-by-step operation or slow driving speed, a significantly longer driving distance is achieved.
The further embodiment of the invention is characterized by a dimensioning of the electrical device such that the speed required for city traffic can be achieved with one battery charge, with a sufficient distance in daily operation.

Die erfindungsgemäße Kombination ermöglicht, daß die elektrische Maschine mit einem viel besseren Wirkungsgrad arbeiten kann und trotzdem erfordert diese Lösung keinen wesentlichen zusätzlichen Materialaufwand. Die Erfindung erlaubt ein konventionelles Kraftfahrzeug mit dessen praktisch schon vorhandener elektrischer Anlage in einem beschränkten Bereich günstiger und besser zu bewegen und kommt damit einem akuten Bedürfnis gerade in Stadtkerngebieten, Tiefgaragen, Krar.kenhauszufahrten u. ä., auch im Sinne optimaler Umweltbedingungen, mit mäßigem Aufwand sehr entgegen.The combination according to the invention enables the electrical machine to be operated with a much better Efficiency can work and yet this solution does not require any significant additional material expenditure. The invention allows a conventional motor vehicle with its practically already existing one electrical system in a limited area cheaper and better to move and comes thus an acute need, especially in city center areas, underground garages, Krar.kenhaus entrances, etc., also in terms of optimal environmental conditions, with moderate effort very contrary.
