Abstract
Description
Die Erfindung betrifft eine Luftfeder für Fahrzeuge gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an air spring for vehicles according to the preamble of
Luftfedern sind allgemein zwischen Karosserie und Radachse bzw. Fahrwerk angeordnet und wirken in der Regel zusammen mit parallel dazu angeordneten Bewegungsdämpfern, wobei die Luftfeder beispielsweise als luftgefüllter Roll- oder Faltenbalg und der Bewegungsdämpfer als doppelt wirkende pneumatische Kolben-Zylindereinheit mit einer die beiden Dämpferräume verbindenden Drossel ausgebildet ist.Air springs are generally arranged between the body and wheel axle or suspension and usually act together with parallel motion dampers, the air spring, for example, as an air-filled roll or bellows and the motion damper as a double-acting pneumatic piston-cylinder unit with a throttle connecting the two damper chambers is trained.

Bei vielen Anwendungsfällen ist es erwünscht oder erforderlich, eine Abdichtung zwischen der Karosserie und dem Deckel der Gasfeder-Dämpfereinheit vorzusehen, um Schmutzansammlungen am oder im Deckel zu vermeiden. Schmutzansammlungen können nämlich die Bewegung der Luftfederteile im Anschlussbereich, insbesondere des unteren Deckelteils, behindern und somit das Komfortverhalten reduzieren. Es ist hierzu bereits vorgeschlagen worden, an einer geeigneten Stelle des Deckels eine Dichtung aufzukleben. Dies bedeutet jedoch einen zusätzlichen Arbeitsschritt bei der Montage der Gasfeder-Dämpfereinheit; außerdem muss die Dichtung für diesen Anwendungsfall speziell hergestellt werden, was die Teilezahl erhöht.In many applications, it is desirable or necessary to provide a seal between the body and the lid of the gas spring damper unit to prevent buildup of dirt on or in the lid. Dirt accumulations can namely hinder the movement of the air spring parts in the connection area, in particular of the lower cover part, and thus reduce the comfort behavior. It has already been proposed for this purpose to glue a seal to a suitable point of the lid. However, this means an additional step in the assembly of the gas spring damper unit; In addition, the seal must be specially manufactured for this application, which increases the number of parts.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Luftfeder der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, bei der die Anzahl der Montageschritte und der verwendeten Teile gegenüber den bekannten Lösungen reduziert ist.Against this background, the invention has for its object to provide an air spring referred to in the preamble of
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen der Patentansprüche 1 und 3, während eine vorteilhafte Ausgestaltung der Erfindung dem Anspruch 2 entnehmbar ist.The solution to this problem arises from the features of
Der Erfindung liegt die Erkenntnis zugrunde, dass für das Elastomerelement einerseits und eine Abdichtung andererseits Materialien mit ähnlichen bzw. gleichartigen Eigenschaften eingesetzt werden können.The invention is based on the recognition that materials with similar or similar properties can be used for the elastomer element on the one hand and a seal on the other hand.
Demnach geht die Erfindung aus von einer Luftfeder für Fahrzeuge, umfassend einen an einer Montagefläche der Fahrzeugkarosserie montierbaren Deckel mit einem ersten Deckelteil und einem dazu koaxialen zweiten Deckelteil, sowie mit einem zwischen den Deckelteilen angeordneten Elastomerelement, welches die Deckelteile beweglich miteinander verbindet.Accordingly, the invention is based on an air spring for vehicles, comprising a cover which can be mounted on a mounting surface of the vehicle body with a first cover part and a second cover part coaxial therewith, and with an elastomer element arranged between the cover parts, which connects the cover parts to one another in a movable manner.
Zur Lösung der gestellten Aufgabe ist dabei vorgesehen, dass an das Elastomerelement eine kreisförmige Dichtlippe integral angeformt ist, die sich bei der Montage des Deckels an der Montagefläche abdichtend an diese anlegt. Auf diese Weise kann die Dichtlippe im gleichen Arbeitsgang mit dem Elastomerelement hergestellt und mit dem Deckel verbunden werden, so dass einerseits eine eigene, speziell für diesen Anwendungsfall hergestellte Dichtung und andererseits ein zusätzlicher Arbeitsgang für die Montage dieser Dichtung entfallen können.To achieve the object is provided that on the elastomeric element, a circular sealing lip is integrally formed, which applies in the assembly of the lid to the mounting surface sealingly to this. In this way, the sealing lip can be made in the same operation with the elastomeric element and connected to the lid, so that on the one hand own, specially prepared for this application seal and on the other hand, an additional operation for the installation of this seal can be omitted.
In einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Dichtlippe radial nach außen geneigt ausgerichtet ist. Auf diese Weise wird sie beim Ansetzen des Deckels an die Montagefläche der Fahrzeugkarosserie eindeutig und vorhersehbar weiter nach außen verformt.In a preferred embodiment of the invention it is provided that the sealing lip is oriented radially outwardly inclined. In this way, it is unambiguously and predictably further deformed when attaching the lid to the mounting surface of the vehicle body to the outside.
Bei einem Verfahren zur Herstellung eines an einer Montagefläche einer Fahrzeugkarosserie montierbaren Deckels einer Luftfeder mit einem ersten Deckelteil und einem dazu koaxialen zweiten Deckelteil sowie mit einem zwischen den Deckelteilen angeordneten Elastomerelement ist erfindungsgemäß vorgesehen, dass das Elastomerelement in einem Arbeitsgang mit einer an diesem integral angeformten Dichtlippe hergestellt und mit den Deckelteilen verbunden wird.In a method for producing a cover of an air spring which can be mounted on a mounting surface of a vehicle body with a first cover part and a second cover part coaxial therewith, and with an elastomer element arranged between the cover parts, the elastomer element is provided in one operation with a sealing lip integrally formed thereon made and connected to the lid parts.
