Es ist Aufgabe der vorliegenden Erfindung, bei einer Vorrichtung zum Antrieb einer Strömungsmaschine der eingangs genannten Art die thermische Belastung der Regelkupplung zu reduzieren und somit auch den Wirkungsgrad der Antriebsvorrichtung zu erhöhen.It Object of the present invention, in a device for Drive a turbomachine of the type mentioned the thermal load of the control clutch to reduce and thus the efficiency of the drive device to increase.
Die Lösung dieser Aufgabe ergibt sich zunächst aus den Merkmalen des Patentanspruches 1. Erfindungsgemäß sind zwei parallel geschaltete Antriebsstränge vorgesehen, wobei ein Antriebsstrang eine Schaltkupplung und der andere Antriebsstrang eine Regelkupplung enthält. Die Strömungsmaschine, insbesondere ein Lüfter eines Kraftfahrzeuges wird dabei entweder über die Schaltkupplung, d. h. schlupffrei oder über die Regelkupplung (mit Schlupf) angetrieben. Mit der erfindungsgemäßen Antriebsvorrichtung wird der Vorteil erreicht, dass der Lüfter bei hohen Lüfterdrehzahlen über den Antriebsstrang mit Schaltkupplung, d. h. schlupffrei und ohne Entstehung von Verlustwärme angetrieben werden kann, während bei geringeren Lüfterdrehzahlen, also einem geringerem Kühlbedarf der zweite Antriebsstrang mit Regelkupplung gewählt wird. Damit erniedrigt sich auch – gegenüber dem Stand der Technik – die Eingangsdrehzahl der Regelkupplung und deren Lastmoment, welches mit der zweiten Potenz der Drehzahl abnimmt, so dass eine wesentlich geringere Verlustleistung infolge Schlupfes an der Regelkupplung anfällt. Der erfindungsgemäße Antrieb ist für alle Arten von Strömungsmaschinen, die den bekannten Strömungsgesetzen unterliegen, anwendbar, d. h. für mit Schaufeln bestückte Rotoren, die von einem Fluid, gasförmig oder flüssig, kontinuierlich überströmt werden, wobei die Schau feln Arbeit an das Fluid abgeben und an der Rotorwelle Energie zugeführt wird.The solution this task arises first from the features of claim 1. According to the invention are two parallel drive trains provided, wherein a drive train is a clutch and the other drive train contains a control clutch. The turbomachine, in particular a fan a motor vehicle is thereby either via the clutch, d. H. slip-free or over the control clutch (with slip) driven. With the drive device according to the invention the advantage is achieved that the fan at high fan speeds on the Powertrain with clutch, d. H. slip-free and without emergence from waste heat can be driven while at lower fan speeds, So a lower cooling requirement the second drive train with control clutch is selected. Thus humiliated yourself too - compared to the State of the art - the Input speed of the control clutch and its load torque, which decreases with the second power of the speed, making a significant lower power loss due to slip on the control clutch accrues. The drive according to the invention is for all Types of turbomachines, the known flow laws subject, applicable, d. H. For equipped with shovels Rotors which are continuously overflowed by a fluid, gaseous or liquid, the blades give off work on the fluid and on the rotor shaft Energy supplied becomes.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Der die Schaltkupplung enthaltende erste Antriebsstrang weist vorteilhaft die schnellere Übersetzung auf, d. h. i1 > i2, vorzugsweise i1 = 1,3; i2 = 0,9 auf. Der die Regelkupplung enthaltende zweite Antriebsstrang weist somit die langsamere Übersetzung auf. Bei diesem bevorzugten Ausführungsbeispiel ergibt sich für die Regelkupplung gegenüber dem Stand der Technik eine Reduzierung der Schlupfleistung und damit der Verlustwärme von ca. 50 %. Während Regelkupplungen nach dem Stand der Technik – wie oben ausgeführt – beim Hochtrieb mit hohen Eingangsdrehzahlen und hohen Abtriebsdrehzahlen, d. h. hohen Lastmomenten betrieben werden, trifft dies für die erfindungsgemäße Antriebsvorrichtung nicht zu.Advantageous embodiments of the invention will become apparent from the dependent claims. The first drive train containing the clutch advantageously has the faster gear ratio, ie i 1 > i 2 , preferably i 1 = 1.3; i 2 = 0.9. The second drive train containing the control clutch thus has the slower ratio. In this preferred embodiment results for the control clutch over the prior art, a reduction of the slip performance and thus the heat loss of about 50%. While control clutches according to the prior art - as stated above - in high-drive with high input speeds and high output speeds, ie high load torques are operated, this is not true for the drive device according to the invention.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung können die Übersetzungen im ersten und zweiten Antriebsstrang auch getauscht werden, so dass der Antriebsstrang mit der Regelkupplung die schnellere Übersetzung und der Antriebsstrang mit der Schaltkupplung die langsamere Übersetzung aufweisen. Die Vorteile dieser Übersetzungskombination bestehen u. a. darin, dass eine Begrenzung der maximalen Lüfterdrehzahlen (Überdrehzahlen) möglich ist.To In a further advantageous embodiment of the invention, the translations in the first and second powertrain also be swapped, so that the powertrain with the control clutch the faster translation and the powertrain with the clutch the slower translation exhibit. The advantages of this translation combination exist u. a. in that a limitation of the maximum fan speeds (Overspeed) possible is.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist mindestens ein Antriebsstrang als zweiachsiger, form- oder kraftschlüssiger Trieb ausgebildet. Kraftschlüssige Triebe können Riementriebe, insbesondere Keilriementriebe, formschlüssige Triebe können Zahnriementriebe, Kettentriebe, Zahnradgetriebe oder dergleichen sein.In Another advantageous embodiment of the invention is at least a drive train as a biaxial, positive or non-positive drive educated. Frictional Shoots can Belt drives, in particular V-belt drives, form-locking drives can Timing belt drives, chain drives, gear transmission or the like be.
In weiterer vorteilhafter Ausgestaltung der Erfindung fällt die erste Achse des zweiachsigen Triebes mit der Achse der Kurbelwelle zusammen, während die zweite Achse durch eine zur Kurbelwelle parallele Achse mit Befestigung vorzugsweise am Motorblock gebildet wird.In a further advantageous embodiment of Invention, the first axis of the biaxial drive coincides with the axis of the crankshaft, while the second axis is preferably formed by an axis parallel to the crankshaft with attachment to the engine block.
Nach einer bevorzugten Anordnung ist die Regelkupplung auf der Achse der Kurbelwelle und die Schaltkupplung auf der parallelen Achse angeordnet.To a preferred arrangement is the control coupling on the axis the crankshaft and the clutch on the parallel axis arranged.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann auch diese Anordnung von Regel- und Schaltkupplung dahingehend getauscht werden, dass die Regelkupplung auf der zweiten achsparallelen Achse angeordnet und die Schaltkupplung auf der Kurbelwellenachse angeordnet ist.To a further advantageous embodiment of the invention can also this arrangement of control and clutch are exchanged to that the control clutch is arranged on the second axis parallel to the axis and the clutch is disposed on the crankshaft axis.
Vorzugsweise ist die Regelkupplung als drehmomentgeregelte Flüssigkeitsreibungskupplung ausgebildet. Die Schaltkupplung kann als Magnetkupplung (Elektromagnetkupplung) mit Magnetspule und Ankerscheibe ausgebildet sein.Preferably the control clutch is designed as a torque-controlled fluid friction clutch. The clutch can be used as magnetic clutch (electromagnetic clutch) be formed with magnetic coil and armature disc.
Die Aufgabe der Erfindung wird auch durch die Merkmale des Patentanspruches 15 gelöst. Danach ist vorgesehen, dass der erste Antriebsstrang als Durchtrieb mit Schaltkupplung, d. h. koaxial und mit einer Übersetzung von i1 = 1 ausgebildet ist, während der zweite Antriebsstrang zwei hintereinander geschaltete form- oder kraftschlüssige Triebe mit der Regelkupplung enthält, wobei das Übersetzungsverhältnis i2 > 1 ist. Vorteilhaft bei dieser nebengeordneten Lösung ist, dass die Regelkupplung im Abluftstrom des Lüfters liegt und somit gut gekühlt wird.The object of the invention is also achieved by the features of claim 15. Thereafter, it is provided that the first drive train is formed as a through drive with clutch, ie coaxially and with a ratio of i 1 = 1, while the second drive train contains two successive positive or non-positive drives with the control clutch, the gear ratio i 2 > 1 is. An advantage of this sibling solution is that the control clutch is located in the exhaust air flow of the fan and thus is well cooled.
