Antriebsanordnung von Nebenaggregaten an einer BrennkraftmaschineDrive arrangement of ancillary units on an internal combustion engine
Die Erfindung bezieht sich auf eine Antriebsanordnung von Nebenaggregaten an einer Brennkraftmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a drive arrangement for auxiliary units on an internal combustion engine according to the preamble of claim 1.
Durch die DE-OS 27 43 149 ist eine Brennkraftmaschine bekannt, in'deren Abgasstrom ein Abgasturbolader angeordnet ist. Eine der Brennkraftmaschine zugeordnete Gasturbine wird von der Verlustwärme der Brennkraftmaschine angetrieben. Mit der mechanischen Antriebsarbeit der Gasturbine wird ein einem Ladeluftkühler zugeordneter Lüfter angetrieben und über ein Reduziergetriebe erfolgt eine mechanische Ankoppelung der mechanischen Arbeit der Gasturbine an die Kurbelwelle der Brennkraftmaschine. Von Nachteil ist jedoch dabei, daß beim Betreiben der Brennkraftmaschine immer wieder Betriebsphasen vorkommen, bei denen die Gasturbine nicht ausreichend von Verlustwärme der Brennkraftmaschine versorgt wird, so daß die Brennkraftmaschine unter Abgabe von Leistung an die Gasturbine diese über die mechanische Ankoppelung antreibt.From DE-OS 27 43 149 an internal combustion engine is known in' whose exhaust gas flow an exhaust gas turbocharger is arranged. A gas turbine assigned to the internal combustion engine is driven by the heat loss from the internal combustion engine. With the mechanical drive work of the gas turbine a fan assigned to a charge air cooler is driven and the mechanical work of the gas turbine is mechanically coupled via a reduction gear to the crankshaft of the internal combustion engine. A disadvantage is, however, that when operating the internal combustion engine, there are always operating phases in which the gas turbine is not sufficiently supplied with heat loss from the internal combustion engine, so that the internal combustion engine while delivering power to the gas turbine, it drives it via the mechanical coupling.

Aufgabe der Erfindung ist es, bei einer mechanisch an die Brennkraftmaschine angekoppelten Gasturbine zu verhindern, daß diese über die Ankoppelung durch die Brennkraftmaschine angetrieben wird, und daß sich Gleichlauf-Schwankungen von der Gasturbine über die Ankoppelung auf die Brennkraftmaschine übertragen.The object of the invention is to prevent, in a gas turbine mechanically coupled to the internal combustion engine, that this via the coupling through the internal combustion engine is driven, and that there are wow and flutter from the gas turbine on the coupling the internal combustion engine transmitted.
Erfindungsgemäß wird diese Aufgabe durch die gekennzeichneten Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is characterized by the Features of claim 1 solved.
Weitere Merkmale der Erfindung beinhalten die Unteransprüche. Further features of the invention are contained in the subclaims.
Die erfindungsgemäße Ausgestaltung der mechanischen Ankoppelung der Gasturbine an die Kurbelwelle der Brenn- kraftmaschine weist den Vorteil auf, daß z.B. bei einer von der Brennkraftmaschine bereitgestellten' geringen Abgasmenge und bei einer gleichzeitigen hohen Brennkraftmaschin endrehzahl die. Gasturbine nicht von der Antriebsleistung der Brennkraftmaschine angetrieben wird, sondern nur die zum Betreiben des Lüfters erforderliche Antriebsleistung von der Brennkraftmaschine zur Verfügung gestellt wird. Bedarf es keiner Antriebsleistung für den Lüfterantrieb, so wird die von der Gasturbine bereitgestellte mechanische Arbeit ausschließlich der Brennkraftmaschine zugeführt.The inventive design of the mechanical coupling of the gas turbine to the crankshaft of the combustion engine has the advantage that, for example, with a small amount of exhaust gas provided by the internal combustion engine and with a simultaneous high internal combustion engine final speed the. Gas turbine does not depend on the drive power the internal combustion engine is driven, but only that required to operate the fan Drive power is made available by the internal combustion engine. No drive power is required for the fan drive, the mechanical work provided by the gas turbine is exclusively the Internal combustion engine supplied.
In der Zeichnung wird eine beispielsweise Ausführungsform der Erfindung gezeigt. An example embodiment of the invention is shown in the drawing.
