Description

Verbesserte KUhlungsvorrichtung für Kupplungene insbesondere an Nutzfahrzeugen Die Erfindung betrifft die Verbesserung der Kühlung von Kupplungen in Kraftfahrzeugen und dergleichen. Bekanntlich fühit die Benutzungsweise von Nutzfahrzeugen zu einer starken Anwendung der Kupplung, woraus wegen der Reibung an den Kupplungsbelägen eine starke Erwärmung resultiert, die schädlich für Wirksamkeit und Lebensdauer der Kupplung ist. Die htr entwickelte Wärme muse so schnell wie möglich abgeführt werden.Improved cooling device for clutches, especially on commercial vehicles The invention relates to improving the cooling of clutches in motor vehicles and the same. As is well known, the way commercial vehicles are used leads to a heavy use of the clutch, which is due to the friction on the clutch facings a strong warming results, which is detrimental to effectiveness and lifespan the clutch is. The heat developed htr had to be dissipated as quickly as possible will.

Die erfindungsgemäße Kupplung ist daher im wesentlichen dadurch gekennzeichnet, dass ihre feststehenden und Ihre bewegten Teile miteinander eine Turbomaschine bilden, mit der eine heftige Luftzirkulation erzeugt und eine kräftige Kühlung der Kupplung herbeigeführt wird. Weitere Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispiels für eine derartige Kupplung, die in der Zeichnung schematisch im Schnitt dargestellt Ist.The coupling according to the invention is therefore essentially characterized by that your fixed and your moving parts together form a turbo machine, with which a strong air circulation is generated and a powerful cooling of the clutch is brought about. Further features of the invention result from the following description of an exemplary embodiment for such a Coupling, which is shown schematically in the drawing in section.

In der Zeichnung ist eine Kupplung 1 mit der Hauptwelle 9 zu erkennen, umgeben von einem Kupplungsgehäuse 8 und erfingungsgemäß versehen mit einer Trennwand 2, die vorzugsweise drehsymmetrisch um die Welle 9 verläuft und In deren Mitte sich eine Öffnung 3 passender Grösse befindet; die Öffnung umgibt vorzugsweise die Hauptwelle g.In the drawing, a coupling 1 with the main shaft 9 can be seen, surrounded by a coupling housing 8 and according to the invention provided with a partition 2, which preferably runs in a rotationally symmetrical manner around the shaft 9 and in the center of which there is an opening 3 of a suitable size; the opening preferably surrounds the main shaft g.

Der Rand der Trennwand 2 ist an dem Gehäuse 8 befestigt, das an jeweils einer Seite der Trennwand 2 eine Reihe Öffnungen 6 bzw.-7 aufweist, cle dem Austritt bzw. dem Eintritt von Kühlluft dienen.The edge of the partition 2 is fastened to the housing 8 , which has a row of openings 6 or -7 on each side of the partition 2, cle serve for the exit or entry of cooling air.

Die Kupplung 1 weist zur Trennwand 2 hin gerichtet eine Wand 1 a auf, die nicht rotationasymmetrisch zu der Welle 9 gestaltet Ist und zum Beispiel Vorsprünge 1 b oder Eintiefungen aufweist.The coupling 1 has a wall 1 a directed towards the partition 2, which is not designed to be rotationally asymmetrical to the shaft 9 and has, for example, projections 1 b or depressions.

Die beschriebene Vorrichtung arbeitet folgendermaßen: Wenn die Kupplung 1 arbeitet, entsteht dank der Vorsprünge 1 b und der Eintiefungen in der Wand 1 a der Kupplung eine Turbinenwirkung; die VorsprUnge und Eintiefungen stellen Flügel einer LUftungseinrichtung dar. Die durch die Öffnung 6 (Pfeile 5) ausgestoßene erwärmte Luft wird durch kühle Luft ersetzt, die durch die Öffnungen 7 und die Öffnung 3 (Pfeile 4) angesaugt wird. Es können zusätzlich Plügel 10 an der umlaufenden Wand 1 a angebracht werden, um die Wirksamkeit der Lüftung zu verbessern. Die beschriebene Ausbildung der Belüftung soll keine Einschränkung der Erfindung bedeuten; es lass'en sich Änderungen des Aufbaus vornehmen, die noch im Rahmen der Erfindung liegen.The device described works as follows: When the clutch 1 works, a turbine effect is created thanks to the projections 1 b and the recesses in the wall 1 a of the clutch; the projections and recesses represent wings of a ventilation device. The heated air expelled through the opening 6 (arrows 5) is replaced by cool air which is sucked in through the openings 7 and the opening 3 (arrows 4). Plügel 10 can also be attached to the circumferential wall 1 a in order to improve the effectiveness of the ventilation. The design of the ventilation described is not intended to imply a restriction of the invention; changes to the structure can be made which are still within the scope of the invention.
