Abstract
Description
Die Erfindung bezieht sich auf ein Antriebssystem für insbesondere Kraftfahrzeuge mit mindestens zwei Antriebsmotoren, von denen ein Antriebsmotor eine Hubkolbenbrennkraftmaschine ist und beide Antriebsmotoren über ein Getriebeelement sowohl einzeln als auch zusammen als Fahrzeugantrieb schaltbar sind.The The invention relates to a drive system for in particular motor vehicles with at least two drive motors, one of which is a drive motor a reciprocating internal combustion engine and both drive motors via a Transmission element both individually and together as a vehicle drive are switchable.
Antriebssysteme
zum Antrieb eines Fahrzeuges mit zwei oder mehr Antriebsmotoren
sind allgemein bekannt. So ist es beispielsweise aus der
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Antriebssystem für insbesondere ein Kraftfahrzeug zu schaffen, dass sich unter Verwendung eines einzigen Kraftstoffsystems durch geringen Bauraum, eine leichte Bauweise und durch eine reduzierte Anzahl an Baukomponenten auszeichnet.Of these, Based on the object of the invention, a drive system for in particular to create a motor vehicle that is using a single fuel system by small space, a slight Design and characterized by a reduced number of components.
Die Aufgabe ist erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.The Task is inventively by the characterizing features of claim 1 solved.
Das erfindungsgemäße Antriebssystem umfasst in vorteilhafter Weise eine Hubkolben- und eine Kreiskolbenbrennkraftmaschine, die beide als Brennkraftmaschinen von einem Kraftstoffsystem aus versorgt werden können.The Drive system according to the invention advantageously comprises a reciprocating and a rotary piston internal combustion engine, both as internal combustion engines from a fuel system can be supplied.
Ein weiterer Vorteil besteht in der Kombination der Hubkolbenbrennkraftmaschine mit einer Kreiskolbenbrennkraftmaschine, welche kompakt baut, so dass insgesamt ein Antriebssystem gegeben ist, dass mit einem sehr geringen Bauraum auskommt und daher für den Antrieb von Kraftfahrzeugen hervorragend geeignet ist.One Another advantage is the combination of reciprocating internal combustion engine with a rotary piston internal combustion engine, which builds compact, so that a total drive system is given that with a very requires little space and therefore for the drive of motor vehicles is outstanding.
Schließlich ist auch noch von Vorteil, dass die Kreiskolbenbrennkraftmaschine mit weniger Baukomponenten auskommt als eine Hubkolbenbrennkraftmaschine und daher auch wesentlich leichter baut, so dass durch diese Kombination von Hubkolben- und Kreiskolbenbrennkraftmaschine ein insgesamt leicht bauendes Antriebsaggregat gegeben ist.Finally is also still advantageous that the rotary piston engine with fewer components than a reciprocating internal combustion engine and therefore also much easier to build, so that through this combination of reciprocating and Rotary piston internal combustion engine a total of easy-build drive unit given is.
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Antriebssystems sind Gegenstand der Unteransprüche.Further advantageous embodiments of the drive system according to the invention are the subject of Dependent claims.
In der Zeichnung sind drei Ausführungsbeispiele für ein erfindungsgemäßes Antriebssystem dargestellt.In the drawing are three embodiments for a illustrated drive system according to the invention.
