Description

Die Erfindung betrifft einen emissionsfreien Hybridmotor, der insbesondere für Kraftfahrzeuge vorgesehen ist.The invention relates to an emission-free hybrid engine, which in particular is intended for motor vehicles.

Aus dem Stand der Technik sind verschiedene Maßnahmen zur Emissions­ senkung bekannt. So sind z. B. mit einer Batterie betriebene Elektrofahrzeuge mit einem zusätzlichen Verbrennungsmotor ausgerüstet. Je nach Konzeption wird das Fahrzeug durch diesen Verbrennungsmotor entweder zeitweise mit angetrieben oder der Verbrennungsmotor treibt einen Generator, durch den die Batterie nachgeladen wird.Various measures for emission are from the prior art known reduction. So z. B. powered by a battery electric vehicles equipped with an additional internal combustion engine. Depending on the concept the vehicle is either temporarily with this internal combustion engine driven or the internal combustion engine drives a generator through which the battery is recharged.

Diese Fahrzeuge weisen letztlich auf Grund des Verbrennungsmotors. keine Emissionsfreiheit auf, die jedoch zunehmend gerade für Großstädte bzw. Ballungsgebiete gefordert wird.Ultimately, these vehicles are due to the internal combustion engine. no Zero emissions, which is increasingly becoming a problem for large cities and Conurbations is required.

Elektrofahrzeuge ohne Zusatzantrieb sind grundsätzlich emissionsfrei, haben aber den entscheidenden Nachteil, daß die Batterien an stationären Ladesta­ tionen geladen werden müssen. Während der relativ langen Ladezeitdauer sind die Fahrzeuge nicht einsatzfähig, was zu hohen Betriebskosten führt. Gerade bei herkömmlichen Blei-Säure-Batterien kann die Ladezeitdauer nicht verkürzt werden, da Batterien dieses Typs bei unzulässig hohen Ladeströmen irreversibel geschädigt werden.Electric vehicles without additional drive are basically emission-free but the crucial disadvantage that the batteries on stationary charging tion must be loaded. During the relatively long charging time the vehicles are not operational, which leads to high operating costs. Especially with conventional lead-acid batteries, the charging time cannot be shortened because batteries of this type with impermissibly high charging currents be irreversibly damaged.

Es ist demzufolge die Aufgabe der Erfindung, eine Motoranordnung bereitzu­ stellen, die keine Emissionen verursacht und die Nachteile von reinen Elektro­ antrieben vermeidet.It is therefore the object of the invention to provide a motor arrangement places that causes no emissions and the disadvantages of pure electrical avoids drives.

Die Aufgabe wird mit einem Hybridmotor nach Anspruch 1 gelöst, wonach der Hybridmotor wenigstens einen Elektromotor aufweist, der mit einer Bat­ terie betrieben wird. Weiterhin ist wenigstens ein Preßluftmotor vorgesehen, der mit komprimierter Luft aus einem Preßlufttank gespeist wird. Mit dem Preßluftmotor wird ein Generator betrieben, der Elektroenergie zur Aufladung der Batterie bereitstellt.The object is achieved with a hybrid engine according to claim 1 the hybrid motor has at least one electric motor with a bat  terie is operated. Furthermore, at least one compressed air motor is provided, which is fed with compressed air from a compressed air tank.

  • - Im Betriebszustand 2 laufen der Elektromotor und der Preßluftmotor gleich­ zeitig. Das ist der Fall, wenn entschieden worden ist, daß die Batterie zu la­ den ist, oder wenn entschieden worden ist, die Antriebsleistung des Preß­ luftmotors als mechanische Hilfsleistung dem Elektromotorantrieb zuzuschal­ ten.- In operating state 2, the electric motor and the compressed air motor run the same in time.

Es ist also zweckmäßig, die Batterietemperatur in einem vorbestimmten Bereich zu halten. Daher ist eine thermische Kopplung zwischen der Batterie und dem Preßlufttank und/oder der Luftaustragleitung ausgebildet, so daß die beim Ausströmen oder Einströmen der Preßluft bewirkte Temperaturabsenkung oder -erhöhung des Preßlufttanks wahlweise auf die Batterie übertragbar ist.According to claim 3, a controllable battery temperature control device is provided. It is well known that especially lead-acid batteries are too high sensitive or too low temperature. So it’s convenient to keep the battery temperature in a predetermined range. thats why a thermal coupling between the battery and the compressed air tank and / or the air discharge line, so that the outflow or inflow of the compressed air brings about a temperature decrease or increase the compressed air tank is optionally transferable to the battery.

Nach Anspruch 4 hat ein Fahrzeug, das mit dem erfindungsgemäßen Hybrid­ motor ausgerüstet ist, Solarzellen, die die Batterie während der Fahrt oder im Stillstand laden, wobei dem Fachmann klar ist, daß die Solarzellen lediglich einen Teil der benötigten Energie bereitstellen können.
