Description
Die Erfindung bezieht sich auf eine druckflüssigkeitsbetätigte Reibungskupplung, insbesondere eine T Mernbr. mkupplung, und bezweckt eine 1 wirksame Kühlung der sich insbesondere bei häufiger, nur kurzzeitig unterbrochener Betätigung stark erwärmenden Kupplungsteile.The invention relates to a hydraulic fluid operated friction clutch, in particular a T Mernbr. mkupplung, and aims to 1 effective cooling of the strongly heated in particular in common, only briefly interrupted actuation coupling parts.
Erreicht wird dies erfindungsgemäß dadurch, daß die Kt@plunn der Druckflüssig keit.ständig durch-strömt wird,- wobei der Anpreßcruck -durch ein in der Druckflüssigkeitsableitung eingebautes Drosselorgan geregelt wird. Die von der Druckflüssigkeit aufgenommene Reibungswärme wird somit laufend abgeführt. Von besonderem Vorteil ist die erfindungsgemäße Art der Kühlung insofern, als gerade die durch eine Außenluftkühlung schlecht zu erfassenden inneren Kupplungsteile wirksam gekühlt werden. Das in der Druckflüssigkeitsableitung zur Regelung des Anpreßdruckes vorgesehene Drosselorgan kann, wenn erforderlich, in besonderer Weise gesteuert werden, beispielsweise so, daß der Anpreßdruck in Abhängigkeit von der Kupplungsdrehzahl veränderlich ist.This is achieved according to the invention characterized in that the Kt @ plunn the pressure liquid is keit.ständig By J h- flows, - wherein the Anpreßcruck is regulated -by a built-in pressure of the liquid discharge throttle element. The frictional heat absorbed by the hydraulic fluid is thus continuously dissipated. The type of cooling according to the invention is particularly advantageous insofar as it is precisely the inner coupling parts that are difficult to grasp by external air cooling that are effectively cooled. The throttle element provided in the hydraulic fluid discharge line for regulating the contact pressure can, if necessary, be controlled in a special way, for example so that the contact pressure is variable as a function of the clutch speed.
Zur Verstärkung der Kühlwirkung kann insbesondere in den Fällen, in denen die Druckflüssigkeit im geschlossenen Kreislauf durch die Kupplung geführt wird, in weiterer Ausgestaltung der Erfindung in den Druckflüssigkeitsstrom eine besondere Kühleinrichtung eingebaut werden. Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung.To increase the cooling effect, especially in the cases in where the hydraulic fluid is passed through the coupling in a closed circuit is, in a further embodiment of the invention in the hydraulic fluid flow a special cooling device can be installed. The figure shows an exemplary embodiment the invention.
Die dargestellte, das Drehmoment einer nicht gezeigten Brennkraftmaschine übertragende Reibungskupplung besteht aus einem auf der Welle 2 aufsitzenden äußeren Kupplungsteil i und zwei mit Reibflächen 3 und 4 versehenen, auf einer Welle 5 sitzenden Ku pplungsmembranen 6 und 7. Bei Inbetriebnahme der @l upplung w°ir txrceine-Fumpe 8 Druckflüssigkeit aus dem Vorratsbehälter 9 über das Schaltventil io, die Leitung ii und eine in der Welle befindliche Bohrung 1,2 in den von den beiden Kupplungsmembranen gebildeten Druckraum 13 gefördert. Aus diesem Druckraum führt eine Leitung 14 zu einer in der Welle 5 befindlichen Bohrung 15, welche wiederum über einen Ringraum 16 und eine Leitung 17 mit dem Vorratsbehälter 9 in Verbindung steht. Der auf diese Weise zustande gekommene Flüssigkeitsumlauf wird durch ein in die Rückflußleitung 17 eingebautes Ventil 18 gedrosselt, so daß der Druck im Druckraum 13 der Membranen ansteigt und letztere mit ihren Reibflächen 3 und 4 gegen den Kupplungsteil i gepreßt werden. Über das Gestänge i9 wird das Drosselventil 18 vom Steuerstand der Brennkraftmaschine aus so gesteuert, daß der Anpreßdruck in der Kupplung und damit das von dieser übertragbare Drehmoment in weiten Grenzen veränderlich ist. Zwecks Rückkühlung der sich beim Durchfluß durch die Kupplung erwärmenden Druckflüssigkeit ist in die Rückflußleitung 17 eine an die Kühlwasserzuflußleitung der Brennkraftmaschine angeschlossene Kühleinrichtung 2o eingebaut.The illustrated friction clutch transmitting the torque of an internal combustion engine, not shown, consists of an outer clutch part i seated on the shaft 2 and two clutch membranes 6 and 7, which are provided with friction surfaces 3 and 4 and seated on a shaft 5 ir txrceine pump 8 pressurized fluid is conveyed from the reservoir 9 via the switching valve io, the line ii and a bore 1,2 located in the shaft into the pressure chamber 13 formed by the two clutch diaphragms. A line 14 leads from this pressure space to a bore 15 located in the shaft 5, which in turn is connected to the storage container 9 via an annular space 16 and a line 17. The fluid circulation that has come about in this way is throttled by a valve 18 built into the return line 17 , so that the pressure in the pressure chamber 13 of the membranes rises and the latter is pressed with their friction surfaces 3 and 4 against the coupling part i. Via the linkage i9, the throttle valve 18 is controlled from the control station of the internal combustion engine in such a way that the contact pressure in the clutch and thus the torque which can be transmitted by it can be varied within wide limits. For the purpose of recooling the pressure fluid which heats up as it flows through the clutch, a cooling device 2o connected to the cooling water supply line of the internal combustion engine is installed in the return line 17.
