Description
Die Erfindung bezieht sich auf eine Antriebsan ordnung für ein Kraftfahrzeug mit einer unmittelbar und einer über eine Flüssigkeitsreibungskupplung mittel bar getriebenen Achse, wobei die Flüssigkeitsreibungs kupplung aus ineinandergreifenden Innen- und Außenlamel len besteht.The invention relates to a drive regulation for a motor vehicle with an immediate and one medium via a fluid friction clutch bar driven axis, the fluid friction coupling of interlocking inner and outer plates len exists.
Eine solche Antriebsanordnung ist bereits bekannt (GB-PS 13 57 106). Dabei wird vom Motor des Kraftfahr zeuges die eine Achse unmittelbar und die andere Achse über einen Stirnradtrieb od. dgl. und die Flüssigkeits reibungskupplung angetrieben, wobei die Drehzahlen der zur ersteren Achse führenden Welle und der Eingangs welle der Flüssigkeitsreibungskupplung gleich groß sind. Bei normalen Fahrtverhältnissen, also gleicher Drehzahl beider Achsen erfolgt der Kraftfahrzeugantrieb nur über die unmittelbar getriebene Achse, weil die Flüssigkeits reibungskupplung lediglich bei einer vorhandenen Dreh zahldifferenz zwischen der An- und Abtriebsseite ein Drehmoment überträgt. Ergibt sich dagegen, beispiels weise wegen verminderter Bodenreibung der Räder einer Achse, zwischen der An- und Abtriebsseite der Flüssig keitsreibungskupplung ein Drehzahlunterschied, so wird über die Flüssigkeitsreibungskupplung ein Drehmoment weitergeleitet, und es wirken beide Achsen als getrie bene Achsen. Die Flüssigkeitsreibungskupplung ersetzt also mehr oder weniger komplizierte mechanische Einrich tungen zum willkürlichen Zu- und Abschalten der jeweils zweiten Achse.Such a drive arrangement is already known (GB-PS 13 57 106). The engine of the motor vehicle one axis directly and the other axis via a spur gear drive or the like. and the liquid friction clutch driven, the speeds of the to the first axis leading shaft and the input shaft of the fluid friction clutch are the same size. In normal driving conditions, i.e. the same speed Both axles drive the motor vehicle only via the directly driven axis because of the liquid friction clutch only with an existing rotation difference between the input and output side Transmits torque. However, there is, for example wise because of reduced ground friction of the wheels Axis, between the input and output side of the liquid friction clutch a speed difference, so a torque via the fluid friction clutch forwarded, and both axes act as driven plane axes. The fluid friction clutch replaced so more or less complicated mechanical setup instructions for the arbitrary switching on and off of each second axis.
Um diese Wirkung zu verbessern bzw. das übertrag bare Drehmoment zu vergrößern, müßte die Drehzahldifferenz an der Kupplung erhöht werden, was wiederum eine Dreh zahlerhöhung der Antriebswellen und damit eine Vergrößerung der am Anfang und am Ende des ganzen Antriebsstranges not wendigen Getriebe zur Voraussetzung hätte. Eine geringere Drehzahl des Antriebsstranges, in dem die Flüssigkeits reibungskupplung eingeschaltet ist, bringt auch bei ge forderter Höhe des zu übertragenden Drehmomentes ent sprechend große Abmessungen der Flüssigkeitsreibungs kupplung selbst mit sich. Insbesondere ist es dann not wendig, die Anzahl der Lamellen zu vermehren, so daß sich eine beträchtliche Kupplungsabmessung in Achsrichtung er gibt.To improve this effect or the transmission To increase bare torque, the speed difference would have to be increased on the clutch, which in turn is a turn Increase in the number of drive shafts and thus an increase the need at the beginning and at the end of the entire drive train agile gearbox would be required. A lesser Speed of the drive train in which the fluid friction clutch is switched on, also brings ge required amount of the torque to be transmitted ent speaking large dimensions of fluid friction clutch yourself with. In particular, it is then necessary maneuverable to increase the number of slats so that a considerable coupling dimension in the axial direction gives.
Es ist zwar auch schon bekannt, einer Flüssigkeits reibungskupplung antriebsseitig ein Planetengetriebe vor zuschalten (GB-PS 13 57 106), wobei der Planetenradträger vom Motor her angetrieben wird, das Sonnenrad, das mit den Innenlamellen drehfest verbunden ist, eine von zwei Fahrzeugachsen antreibt und das Hohlrad einerseits mit den Außenlamellen in drehfester Verbindung steht und andererseits zur Abnahme des Antriebes der zweiten ge triebenen Achse dient. Hier hat aber die Flüssigkeits reibungskupplung eine ganz andere Funktion; sie dient nämlich als Sperre für das das Ausgleichgetriebe zwi schen den beiden Achsen (Längsausgleich) bildende Pla netengetriebe.Although it is already known, a liquid friction clutch on the drive side a planetary gear connect (GB-PS 13 57 106), the planet carrier is driven by the motor, the sun gear that with the inner lamellae is rotatably connected, one of two Drives vehicle axles and the ring gear on the one hand the outer slats are in a rotationally fixed connection and on the other hand to decrease the drive of the second ge driven axis is used. But here's the liquid friction clutch a completely different function; she serves namely as a lock for the differential between between the two axes (longitudinal compensation) planetary gear.
Demnach liegt der Erfindung die Aufgabe zugrunde, die eingangs geschilderte Antriebsanordnung so zu ver bessern, daß sowohl mit einer kleineren Flüssigkeits reibungskupplung als auch mit kleiner bemessenen Getrie ben an den beiden Enden des Antriebsstranges für die zwei Achsen das Auslangen gefunden wird.Accordingly, the invention is based on the object the drive arrangement described above to ver better that both with a smaller liquid friction clutch as well as with a smaller gearbox ben at both ends of the drive train for the two axes of sufficiency is found.
Die Erfindung löst die gestellte Aufgabe dadurch, daß der Flüssigkeitsreibungskupplung antriebsseitig ein Planetengetriebe mit ange triebenem Planetenradträger vorgeschaltet ist, mit dessen Sonnenrad die Innenlamellen und mit dessen Hohlrad die Außenlamellen drehfest verbunden sind, und daß vom Hohl rad der Abtrieb zur mittelbar getriebenen Achse abge leitet ist.The invention achieves the object by that the fluid friction clutch on the drive side a planetary gear with driven planet gear carrier is connected, with its Sun gear the inner fins and with its ring gear the External slats are rotatably connected, and that of the hollow rad the output to the indirectly driven axis is leading.
Durch diese Anordnung des Planetengetriebes wird die jeweils auftretende Drehzahldifferenz an der Rei bungskupplung wesentlich erhöht, was selbstverständlich auch eine entsprechende Erhöhung des übertragbaren Dreh momentes zur Folge hat. Diese Drehmomenterhöhung bringt in diesem Fall aber keine Vergrößerung der Kupplungs abmessungen mit sich, da durch das Planetengetriebe eben mit wesentlich höheren Drehzahlen gearbeitet wird. Die Drehzahlen der Eingangs- und Abtriebswelle der Flüssigkeitsreibungskupplung braucht dagegen nicht vergrößert zu werden, so daß es auch nicht notwendig ist, die Getriebe an den Enden des Antriebsstranges in ihren Abmessungen zu verändern. Das Auftreten einer erhöhten Relativdrehzahl zwischen den Innen- und Außen lamellen hat schließlich entsprechend der Kennlinie einer solchen Kupplung auch deren raschere Reaktion auf Schlupfänderungen zur Folge.This arrangement of the planetary gear the speed difference occurring at the Rei Exercise clutch significantly increased, which goes without saying also a corresponding increase in the transferable rotation moment. This torque increase brings in this case, however, the coupling is not enlarged dimensions with it because of the planetary gear just work at much higher speeds. The speeds of the input and output shaft of the In contrast, fluid friction clutch does not need to be enlarged so that it is not necessary either is, the transmission at the ends of the drive train to change in their dimensions. The appearance of a increased relative speed between the inside and outside Finally, lamellas have the characteristic such a coupling also its faster reaction on slip changes.
In der Zeichnung ist als Ausführungsbeispiel das Schema einer erfindungsgemäßen Antriebsanordnung darge stellt. In the drawing, this is an exemplary embodiment Scheme of a drive arrangement according to the invention Darge poses.
Vom Motor 1′ eines Kraftfahrzeuges wird die eine Achse 1 unmittelbar angetrieben. Von der Achse 1 wird über einen Winkeltrieb 2 ein Antriebsstrang 3, 4 ange trieben, der über einen weiteren Winkeltrieb 5 die zweite Achse 6 treibt. In dem Antriebsstrang 3, 4 ist eine Flüssigkeitsreibungskupplung 7 mit antriebsseitig angeordnetem Planetengetriebe 8 eingeschaltet. Dabei ist der Planetenradträger 9 mit der Welle 3 drehfest verbunden, während das Sonnenrad 10 auf einer die Innen lamellen 11 tragenden Welle sitzt. Das Hohlrad 12 ist dem Kupplungsgehäuse 13 zugeordnet, in dem die Außen lamellen befestigt sind und von dem der Abtrieb über die Welle 4 zur Achse 6 abgeleitet ist. Es ist selbst verständlich, daß das Kupplungsgehäuse 13 mit einer viskosen Flüssigkeit gefüllt ist.From the engine 1 'of a motor vehicle having an axis 1 is directly driven. From the axis 1 through an angle drive 2, a powertrain 3, 4 is driven, via a further angle drive 5, the second axis 6 is driving. A fluid friction clutch 7 with a planetary gear 8 arranged on the drive side is switched on in the drive train 3, 4 . The planet carrier 9 is rotatably connected to the shaft 3 , while the sun gear 10 is seated on a lamella 11 supporting shaft. The ring gear 12 is assigned to the clutch housing 13 , in which the outer plates are fastened and from which the output is derived via the shaft 4 to the axis 6 . It is self-evident that the clutch housing 13 is filled with a viscous liquid.
