Description
Technisches GebietTechnical area
Die vorliegende Erfindung befasst sich mit einer Befestigungseinrichtung für das Ende eines Rollbalgs aus einem elastomeren Material an einer Luftfeder oder einem Luftfederdämpfer.The The present invention is concerned with a fastener for the end of a rolling bellows made of an elastomeric material on an air spring or a pneumatic spring damper.

Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe, eine gegenüber dem Stand der Technik verbesserte Verklemmung für die Enden eines Schlauchrollbalgs zu erstellen, die auf einfache Weise herstellbar ist und starke Zugbelastungen aufnehmen kann. Eine Vereinfachung der Montage wird angestrebt.Of the Invention is the task of a comparison with the state of Technique improved clamping for the ends of a hose roll to create that is easy to produce and strong Can absorb tensile loads. A simplification of the assembly will sought.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche 2 bis 13 stellen vorteilhafte Weiterbildungen des Erfindungsgegenstandes dar. Bei einer Befestigungseinrichtung der eingangs genannten Art wird eine das Ende des Schlauchrollbalgs umfassende und wenigstens an einer Stelle an seinem Umfang unterbrochene ringförmige Einlage verwendet, die mit dem Ende des Schlauchrollbalgs in eine umlaufende nutförmige Vertiefung an der Befestigungsstelle des Anschlussteils einfügbar ist und von einem die Einlage spannend einfassenden Spannring umschlungen wird. Hierdurch wird eine Befestigung erreicht, bei der der Spann- oder Klemmring nicht mehr über ein Backenfutter radial plastisch deformiert werden muss. Nach Anbringung der Einlage mit dem Rollbalgende in die nutförmige Vertiefung am Anschlussteil genügt es, wenn der Spannring in axialer Richtung über die Einlage gesteckt und damit eine Verklemmwirkung erzielt wird.The Solution of the task is with the characteristics of Claim 1 reached. Subclaims 2 to 13 provide advantageous developments of the subject invention a fastening device of the type mentioned is a the end of the hose roll comprehensive and at least one Place at its circumference interrupted annular insert used with the end of the hose roll in a circumferential groove-shaped depression at the attachment point of the connection part is insertable and of an insert enclosing exciting Strapping ring is wrapped. This achieves a fastening, when the clamping or clamping ring is no longer a jaw chuck must be deformed radially plastically. After attachment of the insert with the Rollbalgende in the groove-shaped depression on the connection part it is sufficient if the clamping ring in the axial direction over put the insert and thus a Verklemmwirkung is achieved.
In vorteilhafter Weise wird die nutförmige Vertiefung durch zwei im Winkel zueinander stehenden Seitenflächen der Nut gebildet. Die Einlage selbst wird mit ihrer Außenseite konisch ausgebildet, so dass sie mit ihren Wänden etwa parallel zu den Seitenflächen der Nut verläuft.In Advantageously, the groove-shaped depression is through two mutually angled side surfaces of the groove educated. The insert itself is with its outside Conically shaped, so they with their walls about runs parallel to the side surfaces of the groove.
Die Unterbrechung an der Einlage erlaubt ein Auseinanderdrücken beim Einlegen in die Nut und ist auch gleichzeitig so ausgebildet, dass sie ein entsprechendes Zusammendrücken zum Einspannen des Rollbalgs durch den aufgesteckten Spannring erlaubt. Außerdem ist die Unterbrechung der Einlage stufenförmig ausgebildet, so dass eine weitgehend gleichmäßige Anpressung am Rollbalg erreicht wird.The Interruption of the insert allows a separation when inserting into the groove and is also designed at the same time, that they are a corresponding compression for clamping the rolling bellows allowed by the attached clamping ring. Besides that is the interruption of the insert is stepped, so that a largely uniform contact pressure is reached on the bellows.
Zur Unterstützung des Aufstecksvorgangs des Spannrings auf die Einlage hat die Außenseite der Einlage eine Einfuhrschräge. In weiterer Ausgestaltung des Erfindungsgedankens wird die Einlage und der Spannring mit ihren aneinander anliegenden Flächen so ausgeführt, dass beim aufgeschobenen Spannring eine selbstklemmende Reibschlussverbindung entsteht.to Support for the attachment process of the clamping ring the insert has the outside of the insert an import slope. In a further embodiment of the inventive concept, the insert and the clamping ring with their abutting surfaces executed so that the deferred clamping ring a self-locking frictional connection arises.
Möglichst ist aber auch, die Einlage mit Sicherungshaken zu versehen, um für den aufgeschobenen Spannring eine Halterung zu erreichen. Um den Aufschiebevorgang des Spannrings nicht zu stören, können die Sicherungshaken wegklappbar ausgebildet sein.preferably But is also to provide the deposit with safety hooks for to reach the deferred clamping ring a holder. To the Aufschiebeporgang the clamping ring not to disturb the securing hooks can be folded away.
Die vorliegende Verbindung eignet sich besonders gut für Schlauchrollbälge deren Enden wulstlos sind. Es ist somit möglich, die Schlauchrollbälge von einem vorgefertigten Schlauch abzulängen.The This compound is particularly suitable for hose bladders whose ends are beadless. It is thus possible, the Schlauchrollbälge cut to length from a prefabricated hose.
Zur Unterstützung der Verbindung der Enden des Schlauchrollbalgs kann das Ende des Schlauchrollbalgs die Einlage und den Spannring umschlingen. Hierdurch wird eine verringerte Zugkraft am Ende des Rollbalgs erreicht.to Supporting the connection of the ends of the flexible hose the end of the hose roll can wrap around the insert and the clamping ring. As a result, a reduced tensile force at the end of the rolling bellows is achieved.
Die Vorbefestigungseinrichtung eignet sich besonders gut für die Anbringung am Rand des Abrollkolbens für den Rollbalg.The Pre-fastening device is particularly suitable for the attachment at the edge of the rolling piston for the rolling bellows.
