Description
Die vorliegende Erfindung befasst sich mit der Befestigung der Enden eines Federbalgs an den Beschlagteilen einer Luftfeder.The The present invention is concerned with attachment of the ends a bellows on the fitting parts of an air spring.
Stand der TechnikState of the art
Bei Luftfedern ist ein gasdicht abgeschlossener Innenraum erforderlich. Die hierfür eingesetzten Federbälge umschließen das Innenvolumen und werden mit ihren Enden an einem Deckel oder dergl. und einem Stützkolben befestigt. Die Befestigung erfolgt dabei über Steckverbindungen oder über Klemmverbindungen. Bei den Steckverbindungen sind die Federbälge mit Endwulsten versehen, die häufig mit darin eingebetteten formsteifen Kernringen ausgestattet sind. Bei Klemmverbindungen werden die schlauchartigen Enden der Federbälge in der Mehrzahl der Fälle durch Klemmringe an entsprechenden Beschlagteilen der Luftfeder festgeklemmt. Die Enden des Federbalgs werden zwischen dem Klemmring und dem in dem Beschlagteil ausgeformten Klemmsitz durch mechanische Verformung des Klemmrings verpresst. es entsteht eine mechanische Verbindung der Einzelteile und eine Dichtheit der Luftfeder insgesamt. Bei den häufig auftretenden Temperaturveränderungen an den Luftfedern treten unterschiedliche Wärmeausdehnungen zwischen den Klemmringen und den Beschlagteilen und gegebenenfalls auch zwischen den Kernringen in den Endwulsten und den Beschlagteilen der Luftfeder auf. Durch das dann eintretende Kriech- und Setzverhalten der beteiligten Materialien kann es zu Undichtigkeiten bei der mechanischen Verbindung des Federbalgs mit den Beschlagteilen kommen. Dieses wirkt sich nachteilig auf das Federverhalten der Luftfeder aus.at Air springs require a gas-tight closed interior. The bellows used for this purpose enclose the inner volume and are with their ends on a lid or Like. And a support piston attached. The attachment takes place via plug connections or via clamp connections. In the plug connections are the bellows with Endwulsten often with embedded therein dimensionally stable Core rings are equipped. With clamp connections, the tube-like Ends of the bellows in the majority of cases by clamping rings on corresponding fitting parts of the air spring clamped. The ends of the bellows are between the clamping ring and the molded in the fitting part clamping seat by mechanical Deformation of the clamping ring pressed. it creates a mechanical connection of the items and a tightness of the air spring as a whole. at the frequently occurring temperature changes different thermal expansions occur at the air springs between the clamping rings and the fitting parts and if necessary also between the core rings in the Endwulsten and the fitting parts the air spring on. By the then entering creep and setting behavior The materials involved can cause leaks in the mechanical Connection of the bellows come with the fitting parts. This works disadvantageous to the spring behavior of the air spring.

Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt deshalb die Aufgabe zu Grunde, eine Befestigung der Enden eines Federbalgs an den Beschlagteilen einer Luftfeder zu schaffen, welche auch trotz starker Temperaturschwankungen eine sichere Abdichtung der Luftfeder aufrecht erhält und zwar auch über sehr lange Betriebszeiten. Die neue Befestigung soll möglichst einfach in ihrer Ausgestaltung sein und keine Behinderung bei der Montage ergeben.Of the The invention is therefore based on the object, an attachment the ends of a bellows on the fitting parts of an air spring to create, which despite strong temperature fluctuations secure seal the air spring maintains and that also over very long operating times. The new attachment should be as simple as possible in their design and no obstruction during assembly result.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche 2 bis 10 stellen vorteilhafte Ausgestaltungen des Erfindungsgegenstands dar.The Solution of the task is with the characteristics of Claim 1 reached. Subclaims 2 to 10 provide advantageous embodiments of the subject invention.
Bei der erfindungsgemäßen Luftfeder wird im Kontaktbereich zwischen wenigstens einem der Enden des Luftfederbalgs und dem zugehörigen Beschlagteil der Luftfeder eine chemische Verbindung hergestellt. Die bevorzugte Herstellung dieser chemischen Verbindung erfolgt durch ein Klebemittel. Durch das Einbringen eines geeigneten Klebstoffs in den Kontaktbereich zwischen den Enden des Luftfederbalgs und den Beschlagteilen der Luftfeder, wird eine haftende chemische Verbindung hergestellt, die auch unter Temperatureinwirkung und unabhängig vom Kriech- und Setzverhalten der beteiligten Materialien die Gasdichtigkeit der Luftfeder sicherstellt. Das Klebemittel kann vor dem Zusammenfügen des Balgendes und des Beschlagteils auf das Balgende oder auch auf dem Beschlagteil aufgebracht werden. Hier ist eine flächige Auftragung des Klebemittels von Vorteil. Möglich ist aber auch, das Klebemittel vor dem Zusammenfügen des Balgendes und des betreffenden Beschlagteils mit Überschuss in eine oder mehrere auf dem Umfang des Beschlagteils angebrachte Vertiefungen einzufügen. Durch das Aufsetzen des Luftbalgendes wird der Überschuss des Klebemittels zwischen Balg und Beschlagteil verteilt. Dabei sind die Vertiefungen aus umlaufenden Nuten ausgebildet. Diese Möglichkeit ist besonders günstig bei der Verwendung von Klemmringen, da bei der Verpressung des Klemmrings der Klebstoff aus der Vertiefung herausgedrückt und zwischen Balg und Beschlagteil verteilt wird. Der Klebstoff kann dabei so in der Vertiefung untergebracht werden, dass es bei der Montage des Luftfederbalgs nicht zu einem Wegschieben des Klebstoffes kommt. Dabei ist es des Weiteren besonders günstig, wenn der Klebstoff unter Druck aktiviert wird.at the air spring according to the invention is in the contact area between at least one of the ends of the bellows and the associated one Fitting part of the air spring made a chemical compound. The preferred preparation of this chemical compound takes place through an adhesive. By introducing a suitable adhesive in the contact area between the ends of the bellows and The fittings of the air spring, an adhesive chemical compound manufactured, which also under temperature effect and independently of Creep and settling behavior of the materials involved the gas tightness the air spring ensures. The adhesive may be prior to assembly of the bellows and the fitting part on the Balgende or on be applied to the fitting. Here is a plane Application of the adhesive of advantage. It is possible also, the adhesive before assembling the bellows and the relevant fitting with excess in one or more recesses mounted on the circumference of the fitting insert. By placing the Luftbalgendes is the excess of the adhesive between bellows and fitting distributed. The recesses are formed from circumferential grooves. This possibility is particularly favorable at the Use of clamping rings, as in the compression of the clamping ring the glue is pushed out of the recess and between Bellows and fitting part is distributed. The adhesive can be so in The recess will be housed in the mounting of the bellows does not come to a pushing away of the adhesive. It is further especially favorable when the adhesive is activated under pressure becomes.
Die chemische Verbindung kann auch durch einen Vulkanisationsvorgang hergestellt werden, in dem dass bzw. die Enden des Luftfederbalgs an den Beschlagteilen der Luftfeder anvulkanisiert werden.The Chemical compound can also be cured by a vulcanization process be prepared in that or the ends of the bellows vulcanized to the fitting parts of the air spring.
