Die Erfindung befasst sich mit der Anordnung eines Faltenbalgs als Schutzmanschette an einer Luftfeder oder einem Luftfederdämpfer mit einem freistehenden Kreuzlagen-Federbalg.The The invention relates to the arrangement of a bellows as a protective sleeve on an air spring or a pneumatic spring damper with a freestanding Cross-ply bellows.
Stand der TechnikState of the art
Es ist allgemein bekannt, bei Luftfederbeinen mit einem freistehenden Kreuzlagen-Federbalg Faltenbalge als Schutzmanschetten einzusetzen. Dabei wird der obere Teil der Manschette am Topf des Luftfederbeins angebracht, während der untere Teil der Manschette im unteren Bereich des Abrollkolbens bzw. Dämpferteils angebracht wird. Auf diese Weise ist der Kreuzlagen-Federblag vor Verschmutzungen bzw. Beschädigungen geschützt. Derartige Schutzmanschetten können sowohl bei Luftfedern als auch bei Luftfederdämpfern zur Anwendung kommen. Nachteilig ist hierbei, dass für diese Konstruktionen ein relativ großer Bauraum benötigt wird, um die Funktionsfähigkeit des Federbalgs nicht einzuschränken. Zwischen dem Federbalg und der Manschette entsteht ein großer Kollisionsbereich, insbesondere dann, wenn große Winkeländerungen des Fahrwerks entstehen. Dabei können Beschädigungen oder auch eine Funktionseinschränkung sowohl am Federbalg als auch an der Schutzmanschette eintreten.It is well known in air spring struts with a freestanding Cross-ply bellows Use bellows as protective cuffs. The upper part of the cuff is at the pot of the air spring leg attached while the lower part of the sleeve in the lower region of the rolling piston or damper part is attached. In this way, the cross-layer Federblag from contamination or damage protected. Such protective cuffs can Both air springs and air spring dampers are used. adversely here is that for these constructions a relatively large space is needed to the functionality of the bellows not to restrict. Between the bellows and the cuff creates a large collision area, in particular then when big angle changes of the chassis arise. It can damage or a functional restriction enter both the bellows and the protective sleeve.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, hier Abhilfe zu schaffen und eine Anordnung eines Faltenbalgs als Schutzmanschette an einem freistehenden Kreuzlagen-Federbalg herzustellen, welche die oben genannten Nachteile vermeidet. Die Anordnung soll außerdem einfach im Aufbau und in der Fertigung sein. Schließlich soll sie möglichst kostengünstig bei einer hohen Funktionstüchtigkeit zu fertigen sein.Of the Invention is based on the object to remedy this situation and an arrangement of a bellows as a protective sleeve on a freestanding To produce cross-layer bellows, which the above-mentioned disadvantages avoids. The arrangement should also be simple in construction and to be in production. After all should she possible economical at a high functionality to be finished.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche 2 bis 11 enthalten vorteilhafte, weitere Ausbildungen des Erfindungsgegenstands.The solution the object is achieved with the features of claim 1. The dependent claims 2 to 11 contain advantageous, further embodiments of the subject invention.
Bei der erfindungsgemäßen Anordnung der Schutzmanschette an einer Luftfeder wird der eingesetzte Faltenbalg mit einem seiner Enden an der Außenseite des Kreuzlagen-Federbalgs außerhalb des Rollfaltenbereichs befestigt. Das andere Ende des Faltenbalgs wird, wie bisher an sich üblich, bevorzugt am Topf der Luftfeder oder auch des Luftfederdämpfers befestigt. Eine Befestigung am unteren Ende des Kolbens bzw. des Dämpfers ist ebenfalls möglich. Durch diese Anordnung des Faltenbalgs an der Luftfeder bzw. am Luftfederdämpfer und an dem freistehenden Kreuzlagen-Federbalg folgt die Schutzmanschette der Bewegung des Federbalgs. Dadurch wird die Relativbewegung zwischen Balg und Manschette zumindest reduziert und gegebenenfalls völlig vermieden. Eine Kollision zwischen Federbalg und Manschette wird weitgehend aufgehoben. Die Befestigung des als Schutzmanschette wirkenden Faltenbalgs am Kreuzlagen-Federbalg erfolgt außerhalb des Rollfaltenbereichs des Federbalgs, damit der Abrollvorgang der Rollfalte nicht behindert wird.at the inventive arrangement the boot on an air spring becomes the inserted bellows with one of its ends on the outside of the crossply bellows outside attached to the roll fold area. The other end of the bellows will be, as usual in the past, preferably attached to the pot of the air spring or the air spring damper. An attachment at the lower end of the piston or the damper is also possible. By this arrangement of the bellows on the air spring and the air spring damper and on the freestanding cross-layer bellows follows the protective sleeve the movement of the bellows. This will cause the relative movement between Bellows and cuff at least reduced and possibly completely avoided. A collision between bellows and cuff is largely canceled. The attachment of acting as a protective bellows bellows on the crossply bellows takes place outside of the rolling fold area of the Federbalgs, so that the rolling process does not hinder the roll fold becomes.
Die Befestigung des Faltenbalgs am Kreuzlagen-Federbalg kann auf unterschiedliche Weise durchgeführt werden. Dabei kommen sowohl kraft- als auch formschlüssige Verbindungen in Frage sowie auch Haftverbindungen.The Fastening the bellows on the crossply bellows can be different Manner performed become. Here are both positive and positive connections in question as well as adhesive joints.
Eine sehr einfache Befestigung kann dadurch erreicht werden, dass das zu befestigende Ende des Faltenbalgs durch einen Außenring an den Federbalg gepresst wird. Gegebenenfalls kann hier auch ein Innenring zusätzlich verwendet werden und das Ende des Faltenbalgs mit dem betreffenden Abschnitts des Federbalgs zwischen dem Außenring und dem Innenring eingeklemmt werden. In beiden vorstehend genannten Möglichkeiten ist es günstig, wenn der für das Einklemmen vorgesehene Abschnitt des Federbalgs durch eine nach innen gerichtete Einbuchtung gebildet wird.A Very simple attachment can be achieved by that to be fastened end of the bellows through an outer ring pressed against the bellows. If necessary, can also be here Inner ring additionally be used and the end of the bellows with the relevant Section of the bellows between the outer ring and the inner ring clamped become. In both possibilities mentioned above, it is favorable if the for the pinching provided section of the bellows by one after inside inward dent is formed.
Eine ebenfalls sehr einfache Ausführungsform der Befestigung des Faltenbalgs am Federbalg kann dadurch erreicht werden, dass am Befestigungsabschnitt der Federbalg mit einer in eine Balgfalte des Faltenbalgs einfügbaren, ringförmigen Auswölbung versehen ist. Bei der Montage wird die betreffende Balgfalte über die Auswölbung am Federbalg gezogen. Um hier eine möglichst sichere Anbindung zu erreichen, kann hier gegebenenfalls über die Balgfalte noch eine Befestigungsschelle aufgesetzt werden.A also very simple embodiment the attachment of the bellows on the bellows can be achieved be that on the attachment section of the bellows with an in a bellows fold of the bellows insertable, provided annular bulge is. During assembly, the Belgfalte is about the bulge pulled on the bellows. To be as secure as possible reach here, if necessary, via the bellows fold one more Mounting clamp are placed.
Ohne Befestigungsschelle kann eine Befestigung auskommen, bei der das betreffende Ende des Faltenbalgs mit einer Ringnut versehen wird, die als Schnappverbindung auf eine am Federbalg angebrachte Ringwulst aufknöpfbar ist. In vielen Fällen ist eine solche Schnappverbindung ausreichend.Without Mounting clamp can get by a fixture in which the end of the bellows is provided with an annular groove, as a snap connection on an attached to the bellows annular bead aufknöpfbar is. In many cases is such a snap connection is sufficient.
Für die Befestigung des Faltenbalgs am Kreuzlagen-Federbalg können auch Haftverbindungen herangezogen werden und das Ende des Faltenbalgs am Federbalg angeklebt sein. An Stelle der Klebeverbindung kann auch eine Anvulkanisierung erfolgen. Schließlich ist auch eine kraftschlüssige Verbindung möglich, indem beispielsweise an dem Befestigungsabschnitt am Federbalg eine zusammenpressbare Einlage aus einem Polyurethanmaterial aufgebracht wird, die durch das Aufblasen des Federbalgs mit hoher Kraft an den Faltenbalg angepresst wird, so dass dadurch eine kraftschlüssige Verbindung entsteht. Die Einlage wird in ihrer Länge so bemessen, dass der Kraftschluss eine dauerhafte Verbindung ergibt.For the attachment of the bellows on the cross-layer bellows adhesive bonds can be used and the end of the bellows are glued to the bellows. In place of the adhesive bond can also be scorched. Finally, a non-positive connection is possible by, for example, a compressible insert made of a polyurethane material is applied to the attachment portion on the bellows, by the inflation of the Federbalgs is pressed with high force to the bellows, thereby creating a positive connection. The insert is dimensioned in its length so that the adhesion results in a permanent connection.
