Abstract
Schließklappen für Strömungskanäle in Kraftfahrzeugklimaanlagen sind mit einer weichen umlaufenden Dichtlippe versehen, die, da sie zumindest im Bereich der Lagerzapfen an der zugeordneten Wand des Strömungskanals anliegt, zu Verschleiß und zu erhöhten Verstellkräften führt. Es wird vorgeschlagen, im Bereich der Lagerzapfen die Dichtung mit einem Ansatz zu versehen, der aus einem härteren Material besteht und einen geringen Reibungskoeffizienten zur Strömungswand aufweist. Verwendung für Schließklappen von Strömungskanälen in Kraftfahrzeugklimaanlagen.Closing flaps for flow channels in motor vehicle air conditioning systems are provided with a soft circumferential sealing lip, which, since it bears against the associated wall of the flow channel at least in the region of the bearing journal, leads to wear and to increased adjusting forces. It is proposed to provide the seal in the region of the bearing journal with a shoulder which consists of a harder material and has a low coefficient of friction with the flow wall. Use for closing flaps of flow channels in motor vehicle air conditioners.
Description
Die Erfindung betrifft eine Schließklappe für einen Strömungskanal, mit einem Innenkörper, der mit Mitteln zur beweglichen Halterung der Klappe und Übertragung von Klappenbetätigungskräften auf den Innenkörper verbunden ist, und mit einer klappenrandseitigen Dichtlippe, die außen an einem Rahmenteil angeordnet ist, das mit dem Innenkörper über ein elastisches Verbindungselement verbunden ist.The The invention relates to a closing flap for one A lazy river, with an inner body, with means for movably holding the flap and transmission of flap actuation forces the inner body is connected, and with a flap edge sealing lip, the Outside is arranged on a frame part, which is connected to the inner body via a elastic connecting element is connected.

Die
Klappen dieser Art leiden aber unter dem Nachteil, daß zumindest der in der Nähe der Drehachse der Klappe angeordnete Teil der Dichtlippe, um einen dichten Abschluß im Strömungskanal zu erreichen, an der zugeordneten Wand des Strömungskanales anliegt, so daß wegen des zwischen der weichen Dichtlippe und der Strömungskanalwand auftretenden relativ hohen Reibungskoeffizienten auch große Reibungskräfte auftreten, die durch den Antrieb überwunden werden müssen. Sollen diese Reibungskräfte niedriger gehalten werden, so muß ein Schmiermittel verwendet werden, das aber dazu führt, daß solche Schließklappen nicht wartungsfrei sind, was in der Regel aber für solche in Klimaanlagen von Kraftfahrzeugen verwendeten Klappen gefordert wird. Ein gewisser Nachteil kann auch darin gesehen werden, daß aufgrund der hohen Reibung zwischen Dichtlippe und Strömungskanal ein relativ starker Abrieb der Dichtungslippe vorliegt.fold However, this type suffer from the disadvantage that at least the near the axis of rotation the flap arranged part of the sealing lip to a tight seal in the flow channel to reach, applied to the associated wall of the flow channel, so that because of occurring between the soft sealing lip and the flow channel wall relatively high friction coefficients also occur large frictional forces, that overcome by the drive Need to become. Should these frictional forces be kept lower, a lubricant must be used but that leads to that such closing flaps are not maintenance free, which is usually for those in air conditioners Vehicles used flaps is required. Someone specific Disadvantage can also be seen that due to the high friction between Sealing lip and flow channel There is a relatively strong abrasion of the sealing lip.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Schließklappe der eingangs genannten Art so auszubilden, daß die Verwendung von Schmiermittel unnötig wird, ohne daß aber auf die Vorteile solcher Schließklappen verzichtet werden muß.Of the Invention is therefore based on the object, a closing flap of the type mentioned above in such a way that the use of lubricant unnecessary will, but without on the advantages of such closing flaps must be waived.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung bei einer Schließklappe der eingangs genannten Art vorgesehen, daß die Dichtlippe im Bereich des Drehzapfens mit einem an der Wand des Strömungskanales anlegbaren Ansatz versehen ist, der aus einem gegenüber dem Material der Dichtlippe härteren Matertial besteht.to solution This object is achieved according to the invention at a closing flap of the type mentioned provided that the sealing lip in the area of the pivot with an attachable to the wall of the flow channel approach is provided, which from one opposite the material of the sealing lip tougher Matertial exists.
Diese Ausgestaltung erlaubt es, insbesondere wenn zur Herstellung des Anatzes ein Material verwendet wird, das einen sehr niedrigen Reibungskoeffizienten gegenüber der Wand des Strömungskanales aufweist, daß die Betätigungskräfte für die Klappe klein gehalten werden können, ohne daß die zusätzliche Verwendung von Schmiermittel notwendig wird.These Design allows it, especially if for the production of the Anatzes a material is used, which has a very low coefficient of friction across from the wall of the flow channel that the Actuating forces for the flap small can be held without that additional Use of lubricant is necessary.
In Weiterbildung der Erfindung kann der Ansatz dabei aus einem Material bestehen, das dem des Inserts, also des Innenkörpers und/oder des Rahmenteils entspricht. Das in der Regel für die Herstellung des Inserts verwendete relativ biegesteife Polypropylenmaterial besitzt relativ gute Gleiteigenschaften gegenüber dem Material des Strömungskanales, das ebenfalls ein Kunststoff, aber auch Blech sein kann.In Further development of the invention may be the approach of a material exist, that of the insert, so the inner body and / or the frame part equivalent. That usually for the preparation of the insert used relatively rigid polypropylene material has relatively good sliding properties compared to the material of the flow channel, which can also be a plastic, but also sheet metal.
In Weiterbildung der Erfindung kann ein Verbindungskanal zwischen Insert und Außenrand vorgesehen sein, so daß Ansatz und Insert in einem Arbeitsgang gespritzt werden können.In Further development of the invention can be a connection channel between insert and outer edge be provided so that approach and insert can be injected in one operation.
In Ausgestaltung der Erfindung kann schließlich die Dichtlippe im Bereich des Ansatzes verdickt ausgebildet sein, so daß sie den hinter dem Ansatz liegenden Raum dichtend ausfüllt.In Embodiment of the invention may finally the sealing lip in the area be formed thickened the approach so that they are behind the approach Filling in space.
Die Erfindung ist anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und wird im folgenden beschrieben. Es zeigen:The Invention is based on an embodiment shown in the drawing and will be described below. Show it:
