Die Erfindung betrifft einen Hybridantrieb für ein Fahrzeug.The The invention relates to a hybrid drive for a vehicle.
Ein hoher Prozentsatz herkömmlicher Kraftfahrzeuge wird von einem Verbrennungsmotor angetrieben. Bei diesen Kraftfahrzeugen kann die Bremsenergie nicht genutzt werden, da abgesehen von der Starterbatterie kein weiterer Energiespeicher vorgesehen ist, in welchem rückgewonnene Energie abgespeichert werden könnte.One high percentage of conventional Motor vehicles are powered by an internal combustion engine. at these vehicles, the braking energy can not be used, apart from the starter battery no further energy storage is provided, in which recovered Energy could be stored.
Weiterhin ist es bereits bekannt, Kraftfahrzeuge mittels eines Hybridantriebes anzutreiben. Herkömmliche Hybridantriebe weisen einen Verbrennungsmotor und einen Elektromotor auf, die während des Betriebes des jeweiligen Kraftfahrzeugs individuell zu- und abgeschaltet werden können. Bisherige Hybridantriebe sind recht kostspielig. Dies ist im wesentlichen durch die verwendete Speichertechnik und die Leistungselektronik bedingt.Farther It is already known, motor vehicles by means of a hybrid drive drive. conventional Hybrid drives have an internal combustion engine and an electric motor on that during the Operation of the respective motor vehicle individually switched on and off can be. Previous hybrid drives are quite expensive. This is essentially through the used memory technology and the power electronics conditionally.

Ein Hybridantrieb gemäß der Erfindung stellt eine deutlich kostengünstigere Alternative zu den vorbekannten Hybridantrieben dar. Gemäß der Erfindung liegt ein Hybridantrieb vor, der als Hauptantriebseinheit eine Verbrennungsmaschine und als weitere Antriebseinheit eine Druckluftmaschine enthält. Der der Druckluftmaschine zugeordnete Druckluftspeicher ermöglicht im Schiebebetrieb und bei Bremsvorgängen eine Energiespeicherung bzw. einen Druckaufbau im Sinne einer Rekuperation und im Fahrbetrieb einen kurzzeitigen Betrieb des Fahrzeugs durch eine Energieabgabe im Sinne eines Druckabbaus.One Hybrid drive according to the invention represents a much cheaper Alternative to the previously known hybrid drives. According to the invention is a hybrid drive, the main drive unit is an internal combustion engine and as a further drive unit includes a pneumatic machine. Of the the compressed air machine associated compressed air storage allows in Pushing operation and braking an energy storage or a pressure build-up in the sense of recuperation and during driving a short-term operation of the vehicle by an energy release in the sense of a pressure reduction.
Durch die Verwendung einer Druckluftmaschine als weitere Antriebseinheit eines Hybridantriebs werden Kosten eingespart, da Standardtechnologien und preiswerte Standardbauelemente verwendet werden können. Es kommt ein verschleißfreies Speichermedium mit unbegrenzter Zyklenfähigkeit zum Einsatz. Eine Rekuperation bzw. Speicherung der Bremsenergie im Verzögerungsbetrieb kann über einen längeren Zeitraum mit hohem Wirkungsgrad durchgeführt werden. Es tritt keine Einschränkung der. Leistungsfähigkeit des Energiespeichers über der Umgebungstemperatur auf. Weiterhin kann ein Start des Motors des Fahrzeugs ohne Verwendung eines Anlassers durchgeführt werden. Ferner ist ein problemloses Recycling der Bestandteile der Druckluftmaschine möglich.By the use of a compressed air machine as another drive unit A hybrid drive saves costs because of standard technologies and inexpensive standard components can be used. It comes a wear-free Storage medium with unlimited cycle capability for use. A recuperation or storage of the braking energy in the deceleration mode can via a longer Period can be carried out with high efficiency. It does not occur restriction of the. capacity of energy storage over the ambient temperature. Furthermore, a start of the engine of the vehicle without using a starter. Furthermore, a problem-free recycling of the components of the compressed air machine possible.
Die im Druckluftspeicher enthaltene Druckluft kann in vorteilhafter Weise auch zur Beschleunigung eines Turboladers eines Fahrzeugs verwendet werden. Ferner kann die Druckluft sowohl im Fahrbetrieb als auch bei stehendem Fahrzeug weiteren Aggregaten des Fahrzeugs zugeleitet werden, um diese anzutreiben.The compressed air contained in the compressed air reservoir can also be used to accelerate a turbocharger of a vehicle in an advantageous manner become. Furthermore, the compressed air can be supplied to further units of the vehicle both in driving operation and when the vehicle is stationary in order to drive them.
In vorteilhafter Weise weist der Hybridantrieb insgesamt n Zylinder auf, wobei ein Teil dieser Zylinder der Verbrennungsmaschine und die restlichen Zylinder der Druckluftmaschine zugeordnet sind. Dies hat den Vorteil, dass die Verdichtung der der Druckluftmaschine zugeordneten Zylinder wesentlich höher sein kann als die Verdichtung der der Verbrennungsmaschine zugeordneten Zylinder. Vorzugsweise hat das Verdichtungsverhältnis der der Druckluftmaschine zugeordneten Zylinder einen Wert, der größer oder gleich 25 ist.In Advantageously, the hybrid drive has a total of n cylinders on, wherein a part of these cylinders of the internal combustion engine and the remaining cylinders of the pneumatic machine are assigned. This has the advantage that the compression of the compressed air machine associated cylinder can be much higher than the compression the cylinder associated with the internal combustion engine. Preferably has the compression ratio the cylinder assigned to the pneumatic machine has a value that bigger or is equal to 25.

Beispielsweise können ein aktives Fahrwerk bzw. die Stoßdämpfer im Sinne einer Höhen- und Dämpfungsverstellung angesteuert werden. Dazu müssen allerdings zusätzliche Luftkompressoren mitgeführt werden.For example can an active chassis or the shock absorbers in the sense of a height and damping adjustment be controlled.

Als weitere Alternative ist eine Ansteuerung der Ein- und Auslassventilverstellung mittels Druckluft durchführbar.When Another alternative is a control of the inlet and outlet valve adjustment be carried out by compressed air.
Ferner ist durch eine Lufteinblasung in das Aktivkohlefilter eine verbesserte Tankentlüftung erzielbar. Ein Unterdruck im Saugrohr ist dann nicht mehr zwingend notwendig.Further is an improved by an air injection into the activated carbon filter tank ventilation achievable. A negative pressure in the intake manifold is then no longer mandatory necessary.
