Description

Druckmittelbetätigte Lamellenkupplung Die Erfindung betrifft eine druckmittelbetätigte Lamellenkupplung, deren Lamellen im ausgerückten Zustand der Kupplung durch Federkraft auseinandergedrückt werden.Pressure-medium-actuated multi-plate clutch The invention relates to a Pressure medium-actuated multi-plate clutch, the plates of which in the disengaged state of the Clutch can be pushed apart by spring force.

Es ist bekannt, bei derartigen Kupplungen die Lamellen durch ein Kühlmittel, wie Luft oder Öl, zu kühlen, welches das Innere der Kupplung durchströmt und wozu im allgemeinen das Druckmittel benutzt wird, durch welches die Lamellen zur Kupplung zusammengepreßt werden.It is known that in such clutches the lamellae by a coolant, like air or oil, which flows through the inside of the coupling and what for In general, the pressure medium is used through which the disks to the clutch are pressed together.

Obwohl in Leerlaufstellung der Kupplung, d. h. bei voneinander abgehobenen Lamellen, eine unmittelbare Anlage oder ein gegenseitiges Schleifen derselben nicht erfolgt, treten bei den meist hohen Relativgeschwindigkeiten zwischen den voneinander getrennten Lamellen noch wesentliche Reibungsverluste auf, und es findet insbesondere eine unerwünscht große Erwärmung des umlaufenden Kühlöles statt.Although in the neutral position of the clutch, i. H. when lifted from each other Lamellae, direct contact or mutual grinding of the same are not occurs, occur at the mostly high relative speeds between the one another separate lamellas still have significant friction losses, and it takes place in particular an undesirably large heating of the circulating cooling oil takes place.

Zur Vermeidung dieses Nachteiles war es bereits bekannt, das Innere der Kupplung zur Kühlung der Lamellen vom Kühlmittel nur vom Beginn und während der Kupplung durchströmen zu lassen, wobei das Offnen bzw. Schließen der Kühlölleitung mittels eines besonderen, verhältnismäßig umfangreichen Ventilschiebers erfolgt.To avoid this disadvantage, it was already known the interior the clutch for cooling the fins from the coolant only from the beginning and during the clutch to flow through, with the opening and closing of the cooling oil line takes place by means of a special, relatively extensive valve slide.

Gemäß der Erfindung werden druckmittelbetätigte Lamellenkupplungen, deren Lamellen im ausgerückten Zustand der Kupplung durch Federkraft auseinandergedirückt und nur im eingekuppelten Zustand von Kühlöl umspült werden, wobei das Öffnen der Kühlölleitung mittels eines vom Druckmittel betätigten Ventilschiebers erfolgt, dadurch vereinfacht und verbessert, daß als Ventilschieber eine innere, stärker als die übrigen Lamellen ausgebildete Lamelle dient, die einen Kanal aufweist, der beim Einkuppeln mit dem Ölzufuhrkanal in der Kupplungswelle unmittelbar in Verbindung tritt.According to the invention, pressure medium-actuated multi-plate clutches, whose lamellae are pushed apart by spring force in the disengaged state of the clutch and are only washed around by cooling oil in the coupled state, whereby the opening of the The cooling oil line takes place by means of a valve slide actuated by the pressure medium, thereby simplified and improved that as a valve slide an inner, stronger serves as the remaining lamellae formed lamella which has a channel which directly in connection with the oil supply channel in the coupling shaft when coupling occurs.

Die Kupplung nach der Erfindung hat neben der vorerwähnten Vereinfachung und dadurch möglichen Verkürzung der Kupplung auch den Vorteil. daß die Zufuhr des Kühlöles in der Mitte zwischen den Lamellengruppen erfolgen kann, so daß das Ö1 bei öftnung des ölzufuhrkanals auf dem kürzesten Wege nach allen Richtungen schnell zwischen die einzelnen Lamellen gelangen und nach dem Ausschalten der Kupplung auch schnell aus der Kupplung abfließen kann.The coupling according to the invention has in addition to the aforementioned simplification and thereby possible shortening of the coupling also the advantage. that the supply of the Cooling oil can be done in the middle between the lamella groups, so that the Ö1 when the oil supply channel is opened, it takes the shortest route in all directions quickly get between the individual lamellas and also after switching off the clutch can quickly flow out of the coupling.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung im Längsschnitt dar.The drawing shows an embodiment of the invention in longitudinal section represent.

Die Kupplungswelle 10 einer Lamellenkupplung wird durch ein Zahnrad 11 angetrieben. Auf der Welle 10 sitzen die inneren Lamellen 12 axial verschiebbar, aber nicht verdrehbar. Sie werden durch öl-und wärmefeste Gummiringfedern 13 auseinandergedrückt. Das Kupplungsgehäuse 14 ist mit einem Zahnkranz 15 zum Antrieb der Drehung der Kupplung versehen. In dem Gehäuse 14 sind Lamellen 16 vorgesehen, die zwischen die Lamellen 12 greifen. Sie sind im Gehäuse 14 nicht drehbar, wohl aber axial verschiebbar. Zwischen den Lamellen 16 liegen Gummiringfedern 17, die die Lamellen 16 auseinanderspreizen.The clutch shaft 10 of a multi-plate clutch is through a gear 11 powered. On the shaft 10, the inner lamellae 12 are axially displaceable, but not twistable. They are pressed apart by oil-resistant and heat-resistant rubber ring springs 13. The clutch housing 14 is provided with a ring gear 15 for driving the rotation of the clutch Mistake. In the housing 14 lamellae 16 are provided between the lamellae 12 grab. They cannot be rotated in the housing 14, but can be moved axially. Between the lamellae 16 are rubber ring springs 17 which spread the lamellae 16 apart.

Das Einkuppeln erfolgt durch Öldruck, der über eine Leitung 18 in der Welle 10 auf Druckkolben 19 wirkt. Durch die Kolben 19 werden die Lamellen 12 und 16 zusammengepreßt, um den Reibungsverschluß zwischen der Welle 10 und dem Gehäuse 14 herzustellen.The clutch is engaged by means of oil pressure, which is supplied via a line 18 in the shaft 10 acts on the pressure piston 19. The lamellae 12 and 16 compressed to frictionally lock the shaft 10 and the housing 14 to manufacture.

Die mittlere der inneren Lamellen 12, die Lamelle 20, ist verstärkt ausgeführt und enthält einen oder mehrere Kanäle 21. Dieser Kanal 21 dient dazu, beim Betrieb dem Inneren der Kupplung Kühlöl zuzuführen. Die Zufuhr erfolgt über einen Kanal 22 in der Welle 10, der mit der Kühlölpumpe Verbindung hat. Wird die Kupplung durch Druck der Kolben 19 eingekuppelt, so kommen die Kanäle 21 und 22 zur Deckung. Das Kühlöl tritt dann durch die Bohrungen 23 in das Gehäuse 14 ein. Beim Auskuppeln dagegen wird selbsttätig der Kanal 21 gegenüber dem Kanal 22 verschoben. Damit ist der Kühlölzufluß unterbrochen, so daß eine übermäßige Erwärmung des Öles vermieden wird.The middle of the inner lamellae 12, the lamella 20, is reinforced and contains one or more channels 21. This channel 21 is used to to supply cooling oil to the interior of the clutch during operation. The supply is via a channel 22 in the shaft 10, which is connected to the cooling oil pump. Will the Coupling engaged by the pressure of the piston 19, the channels 21 and 22 come for cover. The cooling oil then enters the housing 14 through the bores 23. When the coupling is disengaged, however, the channel 21 is automatically shifted relative to the channel 22. This interrupts the flow of cooling oil, so that excessive heating of the oil is avoided.

Die einzelnen Lamellen sind in an sich bekannter Weise mit radial gerichteten Nuten 24 versehen., durch die das Kühlöl nach außen durch das Gehäuse strömt. Durch eine oder mehrere Bohrungen 25 im Gehäuse fließt das Kühlöl zum Zahneingriff des Kranzes 15 ab.The individual lamellae are radial in a manner known per se Directional grooves 24 provided., through which the cooling oil to the outside through the housing flows. The cooling oil flows through one or more bores 25 in the housing for the meshing of the teeth of the wreath 15.
