Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen für eine Brennkraftmaschine vorgesehenen Assistenzantrieb nach dem Oberbegriff des Anspruchs 1.The The invention relates to an intended for an internal combustion engine Assistance drive according to the preamble of claim 1.
Hintergrund der ErfindungBackground of the invention
Ein
gattungsgemäßer Assistenzantrieb einer Brennkraftmaschine
ist beispielsweise aus der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zu Grunde, einen weiterentwickelten Assistenzantrieb einer Brennkraftmaschine anzugeben.Of the Invention is the object of a further developed Specify assistant drive an internal combustion engine.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch einen Assistenzantrieb mit den Merkmalen des Anspruchs 1. Der Assistenzantrieb umfasst einen Wärmetauscher, welcher mittels eines strömenden Mediums, insbesondere Dampfes, Abwärme der Brennkraftmaschine aufnimmt, sowie eine Expansionsmaschine, welche von dem den Wärmetauscher durchströmenden Medium angetrieben wird. Die Expansionsmaschine dient dem mechanischen Antrieb eines Nebenantriebs der Brennkraftmaschine. Der Nebenantrieb der Brennkraftmaschine ist somit mit Leistung versorgbar, ohne mechanische Leistung von der Brennkraftmaschine abzuzweigen. Die von der Brennkraftmaschine abgegebene thermische Leistung, welche von der Expansionsmaschine in mechanische Leistung umgesetzt wird, wird ohne Umwandlung in andere Energieformen in den Nebenantrieb geleitet.These The object is achieved by an assistant drive with the features of claim 1. The assistant drive comprises a heat exchanger, which by means of a flowing medium, in particular steam, absorbs waste heat of the internal combustion engine, and an expansion machine, which from the heat exchanger flowing through Medium is driven. The expansion machine serves the mechanical Drive a power take-off of the internal combustion engine. The PTO the internal combustion engine is thus supplied with power, without mechanical To divert power from the internal combustion engine. The of the internal combustion engine delivered thermal power, which from the expansion machine is converted into mechanical power, without conversion into other forms of energy passed into the PTO.
Unter einem Nebenantrieb im Sinne des Anspruchs 1 wird einerseits ein Antrieb mindestens eines Nebenaggregats, beispielsweise einer Wasserpumpe, der Brennkraftmaschine, typischerweise eines Kolbenmotors, verstanden. Andererseits wird unter den Begriff „Nebenantrieb” auch ein Hilfsantrieb von Rädern eines mit der Brennkraftmaschine angetriebenen Fahrzeugs subsumiert. Bei den mithilfe des Nebenantriebs angetriebenen Rädern handelt es sich dabei um diejenigen Räder des Fahrzeugs, welche nicht mittels der Brennkraftmaschine angetrieben sind. Beispielsweise ist der Nebenantrieb, in welchen von der Expansionsmaschine erzeugte mechanische Leistung gespeist wird, zum Antrieb der Hinterräder eines Kraftfahrzeugs vorgesehen, welches ansonsten einen Vorderradantrieb aufweist. Der Assistenzantrieb stellt somit ei nen „Soft-Allradantrieb” bereit. Ein besonderer Vorteil eines solchen Allrad-Hilfsantriebs liegt darin, dass kein Antriebsstrang zwischen von der Brennkraftmaschine angetriebenen Rädern und den zusätzlich, nämlich durch die Expansionsmaschine, angetriebenen Rädern – im Extremfall eines einzelnen durch die Expansionsmaschine angetriebenen Rades – benötigt wird.Under a power take-off in the sense of claim 1 is on the one hand Drive at least one auxiliary unit, for example a water pump, the internal combustion engine, typically a piston engine understood. On the other hand, under the term "power take-off" also an auxiliary drive of wheels one with the internal combustion engine driven vehicle subsumes. When using the power take-off driven wheels are those Wheels of the vehicle, which are not by means of the internal combustion engine are driven. For example, the PTO, in which powered by the expansion machine generated mechanical power is, to drive the rear wheels of a motor vehicle provided, which otherwise has a front wheel drive. Of the Assist drive thus provides a "soft four-wheel drive" ready. A particular advantage of such a four-wheel auxiliary drive is in that no drivetrain between the engine driven wheels and in addition, namely through the expansion machine, driven wheels - in extreme cases a single wheel driven by the expander - needed becomes.
Der Wärmetauscher, welcher zur Übertragung thermischer Leistung von der Brennkraftmaschine in die Expansionsmaschine als weiterer Wärmekraftmaschine vorgesehen ist, ist in bevorzugter Ausgestaltung zumindest teilweise in einem von Abgasen der Brennkraftmaschine durchströmten Auspuffkrümmer, insbesondere Fächerkrümmer, angeordnet. Zusätzlich oder alternativ ist Abwärme eines Abgasturboladers für den Betrieb der Expansionsmaschine nutzbar. Das in die Expansionsmaschine einströmende Medium kann damit auf eine besonders hohe Temperatur, insbesondere eine Temperatur von mehr als 600°C, erhihtzt werden. Die Expansionsmaschine ist vorzugsweise als Strömungsmaschine, insbesondere Dampfturbine, ausgebildet.Of the Heat exchanger, which for the transmission of thermal Power from the internal combustion engine in the expansion machine as further heat engine is provided is in a preferred embodiment at least partially in one of exhaust gases of the internal combustion engine flowed through exhaust manifold, especially exhaust manifold, arranged. Additionally or alternatively, waste heat an exhaust gas turbocharger for the operation of the expansion machine available. The medium flowing into the expansion machine can thus be at a particularly high temperature, especially one Temperature of more than 600 ° C, erhihtzt. The expansion machine is preferably as a turbomachine, in particular steam turbine, educated.
Gemäß einer ersten Variante des Assistenzantriebs weist der Nebenantrieb eine mechanische Kopplung ausschließlich mit der Expansionsmaschine, nicht jedoch mit der Brennkraftmaschine, auf. Damit ist insbesondere eine hohe Variabilität hinsichtlich der Einbausituation des Nebenantriebs im mit der Brennkraftmaschine betriebenen Fahrzeug, typischerweise Straßenfahrzeug, gegeben. Ist eine Betriebsbereitschaft des Nebenantriebs auch dann gefordert, wenn die Expansionsmaschine noch keine entsprechende Leistung liefert, so kann als Energiequelle, welche den Nebenantrieb speist, beispielsweise ein elektrischer Energiespeicher oder ein Druckluftspeicher genutzt werden.According to one first variant of the assistant drive, the PTO has a mechanical coupling exclusively with the expansion machine, not however with the internal combustion engine, on. This is in particular a high variability with regard to the installation situation the power take-off in the vehicle powered by the internal combustion engine, typically road vehicle, given. Is an operational readiness the power take-off is also required when the expansion machine does not yet provide any corresponding power, then as an energy source, which feeds the auxiliary drive, for example an electric Energy storage or a compressed air storage are used.
Gemäß einer zweiten Variante des Assistenzantriebs ist der Nebenantrieb mechanisch, vorzugsweise über eine schaltbare Kupplung, mit der Brennkraftmaschine koppelbar. Die mechanische Kopplung zwischen der Brennkraftmaschine und dem Nebenantrieb ist dabei einerseits nutzbar, um mechanische Leistung von der Brennkraftmaschine in den Nebenantrieb einzuspeisen, solange die Expansionsmaschine noch keine oder nur eine unzureichende Leistung abgibt. Zum anderen ist damit auch die Möglichkeit gegeben, von der Expansionsmaschine erzeugte mechanische Leistung über den Nebenantrieb zumindest teilweise in den Antriebsstrang der Brennkraftmaschine zu leiten.According to one second variant of the assistant drive, the auxiliary drive is mechanical, preferably via a switchable clutch, with the internal combustion engine coupled. The mechanical coupling between the internal combustion engine and the power take-off is on the one hand usable to mechanical To feed power from the engine into the PTO, as long as the expansion machine is not or only inadequate Delivers performance. On the other hand is also the possibility given, mechanical power generated by the expander the power take-off at least partially in the drive train of the internal combustion engine to lead.
Unabhängig davon, welche Komponenten mithilfe des Nebenantriebs angetrieben sind, umfasst dieser vorzugsweise ein schaltbares Getriebe, insbesondere ein stufenloses Getriebe. Ein solches beispielsweise als Riemengetriebe oder Reibradgetriebe ausgebildetes stufenloses Getriebe ermöglicht den Betrieb einer vom Nebenantrieb angetriebenen Komponente im optimalen Drehzahlbereich. Dies gilt analog auch in Fällen, in denen der Nebenantrieb zum Radantrieb genutzt wird.Regardless of which components driven by the auxiliary drive, this preferably comprises a switchable transmission, in particular a continuously variable transmission. Such as a belt drive or friction gear formed continuously variable transmission allows the operation of a driven by the auxiliary component in the optimum speed range. This also applies analogously in cases where the auxiliary drive is used for wheel drive.
