Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum direkten torsionsfreien Vorspannen eines Federsystems mit definierter Kraft gegen ein Widerlager. Weiterhin bezieht sich diese auf ein Montageverfahren für ein torsionsfrei vorgespanntes Federsystem sowie schließlich auf einen Spreiz-Klemmverbinder.The The invention relates to a device for direct torsion-free Preloading a spring system with a defined force against an abutment. Furthermore, this relates to a mounting method for a torsion-free preloaded spring system and finally to a spreading clamp connector.
In Ventilsystemen von Schwingungsdämpfern müssen Ventilscheiben und weitere Federelemente mit einer definierten Vorspannkraft eingestellt werden. Das Positionieren der einzelnen Bauteile soll hierbei vorzugsweise torsionsfrei und unmittelbar erfolgen, um Setzeffekte zu vermeiden und die Kennlinienstreuung bzw. Schwankungen durch Reibungseinflüsse bei mittelbarer Krafteinleitung in axialer Richtung (wie z. B. bei einer Gewinde/Mutter-Verbindung) gering zu halten.In Valve systems of vibration dampers have to Valve discs and other spring elements with a defined preload force be set. The positioning of the individual components should hereby preferably torsion-free and immediate, to set effects to avoid and the Kennleistervreuung or fluctuations by friction effects with indirect application of force in the axial direction (such as at a thread / nut connection) to keep low.
Aus
dem Stand der Technik sind Klemmverbindungen bekannt, die für die Einstellung
der Vorspannkraft zunächst
eine translatorische Verschiebung zulassen. Hernach erfolgt dann
eine Fixierung der Klemmverbindung ohne eine Verdrehung relativ zu
dem Federsystem. Entsprechende Klemmverbindungen in Form von Welle-Nabe-Verbindungen oder als
separate Befestigungsorgane werden beispielsweise in der
Der Erfindung liegt daher die Aufgabe zugrunde, das torsionsfreie Vorspannen eines Federsystems gegen ein Widerlager zu vereinfachen und ein entsprechendes System kompakter zu gestalten.Of the The invention is therefore based on the object torsion-free prestressing to simplify a spring system against an abutment and a corresponding system to make it more compact.
Diese Aufgabe wird gemäß Patentanspruch 1 durch eine Vorrichtung zum torsionsfreien Vorspannen eines Federsystems gegen ein Widerlager gelöst, die im folgenden umfasst: ein Hülsenelement zur axialen Abstützung des Federsystems, wobei das Hülsenelement eine Längsöffnung sowie einen Eingriffsabschnitt zur Anordnung in einer Aufnahmeöffnung des Widerlagers aufweist, und einen Schaft, der sich durch die Längsöffnung in den Eingriffsabschnitt des Hülsenelements erstreckt, wobei ein Abschnitt des Schafts und der Eingriffsabschnitt derart konfiguriert sind, dass der Eingriffsabschnitt infolge einer Längsverschiebung des Schafts relativ zu dem Hülsenelement radial in der Aufnahmeöffnung des Widerlagers verspreizt ist.These The object is according to claim 1 by a device for torsion-free pretensioning of a spring system solved against an abutment, comprising: a sleeve member for axial support the spring system, wherein the sleeve member a longitudinal opening as well an engaging portion for disposition in a receiving opening of the Abstützers, and a shaft extending through the longitudinal opening in the engaging portion of the sleeve member extends, wherein a portion of the shaft and the engagement portion are configured such that the engagement portion due to a longitudinal displacement of the shaft relative to the sleeve member radially in the receiving opening of the abutment is gespreizt.
Hierdurch lässt sich eine exakte Positionierung sowie eine schnelle und sichere Fixierung gewährleisten. Der erfindungsgemäße Spreiz-Klemmverbinder aus Hülsenelement und Schaft ist ein kompaktes, platzsparendes Bauteil, das darüber hinaus magazinfähig ist und sich für eine automatisierte Montage eignet.hereby let yourself an exact positioning as well as a fast and secure fixation guarantee. The expansion clamp connector according to the invention from sleeve element and shaft is a compact, space-saving component that is also magazineable and up for an automated assembly is suitable.
Alle für die Montage notwendigen Wege lassen sich translatorisch und koaxial zur Bauteilachse ausführen. Gemäß Patentanspruch 7 ergibt sich ein Montageverfahren, bei dem zunächst das Federsystem zwischen dem Hülsenelement des Spreiz-Klemmverbinders und dem Widerlager eingegliedert und das Hülsenelement mit einem Eingriffsabschnitt in eine Aufnahmeöffnung des Widerlagers eingeführt wird. Daraufhin werden das Hülsenelement und das Widerlager translatorisch gegeneinander verschoben, bis eine vorgegebene Federkraft und/oder ein vorgegebener Federweg eingestellt ist. Danach wird der sich in den Eingriffsabschnitt erstreckende Schaft des Spreiz-Klemmverbinders relativ zu dem Hülsenelement durch Druck oder Zug belastet, wodurch der Schaft den Eingriffsabschnitt des Hülsenelements gegen das Widerlager verspreizt.All for the Mounting necessary ways can be translational and coaxial to the component axis. According to claim 7 results in a mounting method in which initially the spring system between the sleeve element of the expansion clamp connector and the abutment incorporated and the sleeve member with an engaging portion in a receiving opening of the abutment introduced becomes. Then the sleeve element and the abutment translationally shifted against each other until set a predetermined spring force and / or a predetermined spring travel is. Thereafter, the extending into the engagement portion Shaft of the expansion clamp connector relative to the sleeve member loaded by pressure or tension, whereby the shaft of the engaging portion of the sleeve element spread against the abutment.
In vorteilhafter Ausgestaltung wird der Schaft des Spreiz-Klemmverbinders in dem Hülsenelement durch eine translatorische Zug- oder Druckbewegung verkeilt.In advantageous embodiment of the shaft of the expansion clamp connector in the sleeve member wedged a translational tensile or compressive motion.
Nach erfolgter Montage können überstehende Abschnitte des Schafts, die zum Ansatz eines Werkzeugs dienen, entfernt werden. Im Falle einer durch Zug bewirkten Fixierung des Spreiz-Klemmverbinders kann an dem Schaft eine Sollbruchstelle vorgesehen werden, so dass die Fixierung und anschließende Abtrennung des überstehenden Abschnitts in einem Vorgang durchführbar sind.To successful assembly can be supernatant Sections of the shaft, which serve for the approach of a tool removed become. In the case of a train caused by fixation of the expansion clamp connector can be provided on the shaft a predetermined breaking point, so that the fixation and subsequent Separation of the supernatant Section are performed in one operation.
Weitere, vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen angegeben.Further, advantageous embodiments of the invention are specified in the claims.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in:following the invention with reference to an embodiment shown in the drawing explained in more detail. The Drawing shows in:
