Abstract
Description
Die Erfindung betrifft einen Antriebsstrang für ein Kraftfahrzeug, bei dem alternativ entweder über eine Brennkraftmaschine oder über eine elektrische Maschine ein Antriebsmoment erzeugt wird.The The invention relates to a drive train for a motor vehicle, in which alternatively either via a Internal combustion engine or over an electric machine, a drive torque is generated.
Fahrzeuge mit derartigen Antriebssträngen sind bereits vielfach bekannt und teilweise bereits auf dem Markt verfügbar (z.B. Toyota Prius).vehicles with such drive trains are already widely known and partly already available on the market (e.g. Toyota Prius).
Darüber hinaus ist in dem Buch zum 7. LuK Kolloquium, vom 11./12. April 2002, unter dem Titel „Gearing up for tomorrow Take a LuK inside ...", Seite 259–261 ein kupplungsloses zweistufiges Getriebe beschrieben, über welches eine elektrische Startermaschine mittels einem Riemenantrieb an die Kurbelwelle einer Brennkraftmaschine gekoppelt ist.Furthermore is in the book of the 7th LuK Colloquium, from 11./12. April 2002, under the title "Gearing up for tomorrow Take a LuK inside ... ", page 259-261 a clutchless two-stage Gear described above which is an electric starter machine by means of a belt drive is coupled to the crankshaft of an internal combustion engine.
Der Erfindung liegt die Aufgabe zugrunde, einen Antriebsstrang für ein Kraftfahrzeug mit einem konstruktiv vereinfachten und robusten Aufbau anzugeben, insbesondere soll ein Antriebsstrang geschaffen werden, der sich für Kraftfahrzeuge mit hoher Brennkraftmaschinenleistung eignet.Of the Invention is based on the object, a drive train for a motor vehicle with a structurally simplified and robust design, In particular, a drive train is to be created, which is for motor vehicles with high engine power is suitable.
Erfindungsgemäß wird die Aufgabe durch die Gesamtheit der Merkmale des Anspruchs 1 gelöst. Durch die Kopplung der elektrischen Maschine mit der Brennkraftmaschine über eine kupplungsfreie (kupplungslose) zweistufige Getriebeeinrichtung, die derart ausgebildet ist, dass sie in Abhängigkeit von ihrer antriebsseitigen Drehrichtung automatisch zwischen ihren beiden Übersetzungsstufen umschaltet, wird ein einfacher Aufbau eines Antriebsstranges gewährleistet. Durch diese Art der Kopplung ist zwingend stets nur eine Antriebsquelle – entweder Brennkraftmaschine oder elektrische Maschine – zur Erzeugung eines positiven Antriebsmoments aktiv zu schalten. Die elektrische Maschine kann aufgrund der Übersetzung kleiner ausgeführt werden als herkömmliche elektrische Maschinen, die ohne Übersetzung in den Antriebsstrang gekoppelt sind. Ferner kann die Kupplung zwischen Brennkraftmaschine und Fahrzeuggetriebeeinrichtung wie bei einer Auslegung ohne elektrische Maschine dimensioniert werden. Schließlich wird die Kupplung zusätzlich geschont für den Fall beispielsweise, dass der Anfahrbetrieb stets elektrisch erfolgt.According to the invention Problem solved by the entirety of the features of claim 1. By the coupling of the electric machine with the internal combustion engine via a Clutch-free (clutchless) two-stage transmission device, which is designed such that it depends on its drive-side The direction of rotation automatically switches between its two gear ratios ensures a simple construction of a drive train. By this kind The coupling is always necessarily only one drive source - either Internal combustion engine or electric machine - to generate a positive Actuator torque to switch active. The electric machine can smaller due to the translation accomplished be considered conventional electrical machines without translation are coupled in the drive train. Furthermore, the coupling between Internal combustion engine and vehicle transmission device as in a Dimensioning without electrical machine dimensioned. Finally will the clutch in addition spared for the case, for example, that the starting operation is always electric he follows.
Vorzugsweise ist die elektrische Maschine derart dimensioniert, dass mittels ihr ausschließlich ein Anfahrbetrieb bei geringer Lastanforderung (unterhalb einer vordefinierten Lastanforderungsgrenze) erfolgt und bei größerer Lastanforderung (z.B. Volllast/kick-down) ein Antrieb über die Brennkraftmaschine erfolgt.Preferably is the electrical machine dimensioned such that means her exclusively Starting operation with low load request (below a predefined Load request limit) and at a greater load request (e.g. Full load / kick-down) a drive over the internal combustion engine takes place.
Bevorzugt findet der Antriebsstrang Verwendung bei leistungsstarken Fahrzeugen, insbesondere Fahrzeugen mit Heckantrieb.Prefers the powertrain is used in high-performance vehicles, especially vehicles with rear-wheel drive.
Zur Optimierung des Schwerpunktes ist die zweistufige Getriebeeinrichtung unmittelbar auf der Welle zwischen dem Ausgang der Fahrzeuggetriebeeinrichtung und dem Differentialgetriebe der Antriebsachse angeordnet und über ein Kraftübertragungsmittel, wie einen Riemen oder eine Kette, mit der Rotorwelle der elektrischen Maschine verbunden.to Optimization of the center of gravity is the two-stage gear mechanism directly on the shaft between the output of the vehicle transmission device and the differential gear of the drive axle and arranged over a Power transmission means, like a belt or a chain, with the rotor shaft of the electric Machine connected.
Um bei einem elektrischen Antrieb ein ausreichendes Antriebsmoment bereitstellen zu können, und zugleich bei einem generatorischen Betrieb der elektrischen Maschine (beispielsweise im Schubbetrieb des Fahrzeugs oder beim Antrieb über die Brennkraftmaschine) keine zu hohen Drehzahlen der elektrischen Maschine zuzulassen, wird eine Übersetzung der zweistufigen Getriebeeinrichtung von vier zu eins (4:1) gewählt. Dabei stellt sich die Übersetzung 4 (vier) automatisch für den Fall ein, dass die elektrische Maschine motorisch betrieben wird (also als Antriebsmaschine dient), und stellt sich die Übersetzung 1 (eins) automatisch ein, für den Fall des generatorischen Betriebs der elektrischen Maschine.Around In an electric drive sufficient drive torque to be able to provide, and at the same time in a regenerative operation of the electric machine (For example, in overrun mode of the vehicle or when driving via the internal combustion engine) not to allow too high rotational speeds of the electric machine, becomes a translation of the two-stage transmission device selected from four to one (4: 1). there imagine the translation 4 (four) automatically for the case in which the electric machine is operated by a motor is (ie serves as a prime mover), and turns the translation 1 (one) automatically, for the case of the generator operation of the electric machine.
Ferner betrifft die Erfindung gemäß Patentanspruch 4 ein Kraftfahrzeug mit einem, wie vorstehend beschrieben ausgebildeten Antriebsstrang.Further relates to the invention according to claim 4 is a motor vehicle with a, as described above Powertrain.
