Aufgabe der Erfindung ist es, insbesondere für Nutzfahrzeuge einen Antriebsstrang zu schaffen, der einen guten Wirkungsgrad aufweist.task The invention is, in particular for commercial vehicles, a drive train to create, which has a good efficiency.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen von Patentanspruch 1 gelöst.These Task is according to the invention with the Characteristics of claim 1 solved.
Erfindungsgemäß ist zum einen ein Turbo-compound-System vorgesehen. Bei einem solchen System wird eine Abgasturbine von einem Abgasstrom angetrieben. Der Abgasstrom kommt im Fall der Erfindung von einem hinsichtlich des Wirkungsgrades günstigen Dieselmotor. Die Abgasturbine treibt dabei die Kurbelwelle des Antriebsmotors an. Um Schwingungen im Turbo-compound-System auf die Kurbelwelle zu dämpfen, ist im Kraftfluss von der Abgasturbine auf die Kurbelwelle eine hydrodynamische Kupplung angeordnet. Das Turbo-compound-Systems gewährleistet im mittleren und hohen Drehzahlbereich einen hohen Gesamtwirkungsgrad des Antriebsstranges. Der Dieselmotor kann erfindungsgemäß jedoch auch in einem niedrigen Drehzahlbereich bzw. Teillastbereich betrieben werden, ohne dass die im zwangsläufig langsamen Abgasstrom befindliche Abgasturbine und die folgende reibungsbehaftete Übersetzungsstufe die Kurbelwelle herunterbremst und damit den Wirkungsgrad verschlechtert. Dazu wird die Verbindung zwischen der Abgasturbine und der Kurbelwelle geöffnet, wenn ein Drehmoment von der Kurbelwelle eingeleitet wird, anstelle dass ein Drehmoment von der Abgasturbine eingeleitet wird. Damit muss die Kurbelwelle nicht die dem Pumpenrad folgenden reibungsbelasteten Komponenten mitschleppen. Zur Öffnungen der besagten Verbindung ist vorgesehen, die fluidische Verbindung in der hydrodynamischen Kupplung zu trennen, indem das Pumpenrad und das Turbinenrad axial voneinander entfernt werden. Der dann entstehende Breite Spalt verhindert die fluidische Kraftübertragung. Um den Spalt sicher, schnell und definiert zu öffnen kann beispielsweise zusätzliche eine elastische Feder vorgesehen sein. Dadurch, dass keine separate Kupplung zur Öffnung der besagten Verbindung vorgesehen ist, ist die erfindungsgemäße Lösung hinsichtlich des Bauraumes besonders günstig.According to the invention is for one provided a turbo-compound system. In such a system An exhaust gas turbine is driven by an exhaust gas flow. The exhaust gas flow comes in the case of the invention of one in terms of efficiency Great Diesel engine. The exhaust gas turbine drives the crankshaft of the drive motor. To vibrations in the turbo-compound system on to dampen the crankshaft, is in the power flow from the exhaust turbine to the crankshaft one arranged hydrodynamic coupling. The turbo-compound system ensures in the middle and high speed range a high overall efficiency of the Drive train. However, the diesel engine according to the invention also operated in a low speed range or partial load range without necessarily im slow exhaust gas flow exhaust turbine and the following frictional translation stage the crankshaft slows down and thus worsens the efficiency. This is the connection between the exhaust turbine and the crankshaft open, when a torque is introduced from the crankshaft instead that a torque is introduced from the exhaust gas turbine. In order to the crankshaft does not have to bear the friction following the impeller Carry along components. To the openings said connection is provided, the fluidic connection in to separate the hydrodynamic coupling by the impeller and the turbine wheel are axially removed from each other. The resulting width Gap prevents the fluidic transmission. To make sure the gap open quickly and defined can, for example, additional be provided an elastic spring. Because no separate Clutch for opening the said connection is provided, the solution according to the invention is in terms of the installation space particularly favorable.
Die axiale Beabstandung des Pumpenrades gegenüber dem Turbinenrad hat beispielsweise gegenüber einem Freilauf mit Klemmkörpern zur drehmomentrichtungsabhängigen Auftrennung der Verbindung den Vorteil eines praktisch vernachlässigbaren Verschleißes.The axial spacing of the impeller relative to the turbine wheel, for example across from a freewheel with sprags to the torque direction dependent Separation of the compound has the advantage of being practically negligible Wear.
