Abstract
Description
Die vorliegende Erfindung betrifft die Befestigung des äußeren Federbalgendes an der Innenseite eines Verschlussteils einer Luftfeder.The The present invention relates to the attachment of the outer Federbalgendes on the inside of a closure part of an air spring.
Technisches GebietTechnical area
Für die Befestigung von Federbalgenden bei Luftfedern sind verschiedene Methoden bekannt. Weit verbreitet ist das Festklemmen des Federbalgendes über einen Klemmring. Dabei wird das Federbalgende an einen Kolbenrand oder auch an dem oberen Verschlussteil der Luftfeder angelegt und durch einen Klemmring daran festgeklemmt. Bei der Befestigung des Federbalgendes am Kolben ist dieses fertigungstechnisch einfach durchführbar, wobei durch die entstehende Umschlingung des Klemmrings durch das Federbalgende eine gute Abdichtung erreicht wird. Auch können hier sogenannte Schlauchrollbälge verwendet werden, bei denen das Federbalgende eine offene Schnittkante hat, da diese Schnittkante mit dem freiliegenden Fadenmaterial des Balgs außerhalb des Druckraums der Druckfeder liegt. Problematischer ist die Verbindung am Verschlussteil der Luftfeder und zwar in Hinsicht der Fertigungstechnik als auch der angestrebten Dichtheit auch bei sehr hohen Drücken in der Luftfeder.For the attachment of Federbalgenden with air springs are different Methods known. Widely used is the clamping of the Federbalgendes a clamping ring. In this case, the Federbalgende to a piston edge or also applied to the upper closure part of the air spring and through a clamping ring clamped it. When fixing the Federbalgendes on the piston, this manufacturing technology is easy to carry out, wherein by the resulting wrap of the clamping ring by the Federbalgende a good seal is achieved. Also can here so-called Schlauchrollbälge be used, at which the Federbalgende has an open cutting edge, because this cutting edge with the exposed thread material of the bellows outside the pressure chamber of the compression spring is located. More problematic is the connection on the closure part of the air spring and in terms of manufacturing technology as well as the intended tightness even at very high pressures in the air spring.

Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt folglich die Aufgabe zugrunde, eine Befestigungsmöglichkeit für das äußere Federbalgende an der Innenseite eines oberen Verschlussteils bei einer Luftfeder zu finden, bei der das Ende des Balges nicht im Druckraum liegt und die fertigungstechnisch rationell herstellbar ist.Of the Invention is therefore the object of a mounting option for the outer Federbalgende on the inside find an upper closure part in an air spring at the end of the bellows is not in the pressure chamber and the manufacturing technology can be produced efficiently.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche 2 bis 10 stellen vorteilhafte weitere Ausgestaltungen des Erfindungsgegenstandes dar.The Solution of the task is with the characteristics of Claim 1 reached. Subclaims 2 to 10 provide advantageous further embodiments of the subject invention represents.
Gemäß der vorliegenden Erfindung wird das äußere Federbalgende mit seiner Schnittkante außerhalb des Druckraums der Luftfeder liegend um einen Innenring gelegt und durch ein Element des Verschlussteils am Innenring festgeklemmt. Als Element des Verschlussteils kann der Rand eines Deckels oder Topfes dienen. Auch ist es möglich einen Bereich der Topfwand als Verschlussteilelement heranzuziehen. Dieses ist abhängig von der gegebenen Konstruktion des Verschlussteils der Luftfeder.According to the present invention is the outer Federbalgende with its cutting edge outside the pressure chamber of the air spring lying around an inner ring and by an element of the closure part clamped on the inner ring. As an element of the closure part can serve the edge of a lid or pot. It is also possible to use a region of the pot wall as a closure element element. This depends on the given construction of the Locking parts of the air spring.
Die aufgezeigte Befestigungsmöglichkeit des Federbalgendes kann besonders vorteilhaft bei Luftfedern eingesetzt werden, die zusammen mit einem Teleskop-Stoßdämpfer zu einem so genannten Federbein an Kraftfahrzeugen verwendet werden. Dabei ist es in weiterer besonders vorteilhafter Ausgestaltung des Verschlussteils möglich, die Luftfeder mit einem vergrößerten Topf auszuführen, um ein größeres Luftvolumen für die Luftfeder zu schaffen. Hierdurch kann beispielsweise auf einen Behälter mit einem Zusatzluftvolumen verzichtet werden und dennoch ein hoher Fahrkomfort durch die Luftfeder erreicht werden. So kann beispielsweise bei Federbeinen der McPherson-Bauweise ein großvolumiger Topf verwendet werden, an dessen Außenrand ein nach innen gerichtetes Innenelement anbringbar ist, dessen Innenrand als Verschlusselement herangezogen wird. McPherson-Federbeine werden im allgemeinen für die Radaufhängung an Fahrzeugen verwendet, bei der eine Kompensation von Querkräften erforderlich ist.The indicated mounting possibility of Federbalgendes can be used particularly advantageously in air springs, the together with a telescopic shock absorber to one so called strut used on motor vehicles. there it is in a further particularly advantageous embodiment of the closure part possible, the air spring with an enlarged Pot to carry out a larger volume of air to create for the air spring. This can, for example dispensed with a container with an additional air volume be achieved and yet a high ride comfort by the air spring become. For example, with struts of the McPherson design a large-volume pot can be used, at its outer edge an inwardly directed inner element is attachable, the inner edge is used as closure element. McPherson struts will be in general for the suspension of vehicles used in which a compensation of shear forces required is.
Eine vereinfachte Konstruktion für die vorliegende Erfindung kann auch dadurch erreicht werden, dass das Federbalgende durch einen Bereich der Topfwand eines üblichen Topfes am Innenring festgeklemmt wird und der überstehende Rand der Topfwand mit dem Außenrand eines Zusatztopfes größeren Durchmessers luftdicht verbunden wird. In die Wand des kleineren Topfes werden Durchlässe eingebracht, so dass auf diese Weise in Verbindung mit dem Zusatztopf ein Zusatzvolumen für die Luftfederung erreicht wird ohne dass ein außenliegender Zusatzbehälter benötigt wird.A simplified construction for the present invention can also be achieved by the Federbalgende an area of the pot wall of a conventional pot on the inner ring is clamped and the protruding edge of the pot wall larger with the outer edge of a supplementary pot Diameter is connected airtight. In the wall of the smaller one Pot will be introduced passages, so on this Way in conjunction with the additional pot an additional volume for the air suspension is achieved without an outboard Additional container is needed.
Zum Schutz des Federbalgs als auch zu seiner Verstärkung kann um den Innenring auch ein Stützlager gelegt sein, so dass der Innenring vom Stützlager und auch vom Federbalgende umschlungen wird. Auch ist es möglich den Federbalg selbst von einer Außenführung einzufassen. Bei einer Anwendung des Stützlagers und auch einer Außenführung können die genannten Teile über einen Klemmring miteinander verbunden werden.To the Protection of the bellows as well as its reinforcement can around the inner ring also be placed a support bearing, so that the inner ring of the support bearing and also the Federbalgende is entwined. Also it is possible the bellows itself to enclose an external guide. In one application the support bearing and also an external guide can the mentioned parts via a clamping ring be connected to each other.
Schließlich ist es auch möglich in besonderen Anwendungsfällen einen sogenannten Stützring einzusetzen, welcher das an der Innenseite des Innenrings liegende Federbalgteil noch zusätzlich abstützt.After all it is also possible in special cases to use a so-called support ring, which on the the inside of the inner ring lying Federbalgteil even more supported.
