Abstract

The air spring has an elastomeric bellows (3) which is fastened at the top to a pressure chamber (2) by a first ring clip (7) and to a piston (4) by a second ring clip, forming a roll (3) which overlaps it. A guide sleeve (5) fits over this with a protective collar (6) at the top which is fastened between the first ring clip and the top of the bellows.

Description

Die Erfindung betrifft eine Luftfederanordnung, bestehend aus wenigstens folgenden Bauteilen, nämlich:
The invention relates to an air spring arrangement consisting of at least the following components, namely:

  • - einem Luftfederbalg aus elastomerem Werkstoff, der eine volumenvariable Luftkammer einschließt und zumeist mit einem eingebetteten Festigkeitsträger versehen ist (Axialbalg, Kreuzlagenbalg);- A bellows made of elastomeric material, which is a volume variable Air chamber encloses and mostly with an embedded reinforcement is provided (axial bellows, cross-layer bellows);
  • - einem Druckbehälter, an dem das erste Ende des Luftfederbalges mittels eines ersten Klemmringes befestigt ist;- A pressure vessel on which the first end of the air bellows by means of a first clamping ring is attached;
  • - einem Luftfederkolben, an dem das zweite Ende des Luftfederbalges mittels eines zweiten Klemmringes befestigt ist und an dessen Außenwand der Luftfederbalg unter Bildung einer Schlaufe abrollen kann;- An air spring piston on which the second end of the air bellows by means of a second clamping ring is attached and on the outer wall of the air bellows can roll to form a loop;
  • - einer Außenführung für den Luftfederbalg, insbesondere in Verbindung mit einem Axialbalg; sowie ferner aus- An outer guide for the air bellows, especially in connection with one Axial bellows; as well as from
  • - einer Schutzmanschette, die zwei Halteelemente umfasst, nämlich- A protective sleeve, which comprises two holding elements, namely
  • - ein erstes Halteelement, das sich im Bereich des ersten Endes des Luftfederbalges befindet; sowie- A first holding element, which is in the region of the first end of the Air bellows located; such as
  • - ein zweites Halteelement, das wenigstens teilweise die Außenführung außenseitig umgreift.- A second holding element, which is at least partially the outer guide encompasses the outside.

Eine gattungsgemäße Luftfederanordnung ist aus dem Gebrauchsmuster DE-U-298 23 508 (Fig. 1) bekannt. Die Anbindung der Außenführung am Druckbehälter, die auch eine größere kardanische Auslenkung ermöglichen soll, erfolgt mittels einer Schutzmanschette. Das erste Halteelement der Schutzmanschette ist dabei zwischen dem ersten Klemmring und einer Schelle angeordnet. Ein derartiges Anbindungskonzept ist aufwendig und kostenintensiv. Vor allem ist hiermit eine aufwendige Positionierung des ersten Klemmringes erforderlich. A generic air spring arrangement is known from utility model DE-U-298 23 508 ( Fig. 1). The outer guide is connected to the pressure vessel, which is also intended to allow greater gimbal deflection, by means of a protective sleeve. The first holding element of the protective sleeve is arranged between the first clamping ring and a clamp. Such a connection concept is complex and cost-intensive. Above all, a complex positioning of the first clamping ring is required.

Die Aufgabe der Erfindung besteht nun darin, die Schutzmanschette so auszufegen, dass mit ihrer Hilfe der erste Klemmring bei der Montage positioniert werden kann, so dass dadurch das Verklemmen des Luftfederbalges mit dem Druckbehälter wesentlich vereinfacht wird.The object of the invention is now to sweep out the protective sleeve that with their help the first clamping ring can be positioned during assembly, so that the jamming of the air bellows with the pressure vessel is essential is simplified.

Gelöst wird diese Aufgabe gemäß Kennzeichen des Patentanspruches 1 dadurch, dass sich das erste Halteelement der Schutzmanschette zwischen dem ersten Ende des Luftfederbalges und dem ersten Klemmring befindet.This object is achieved in accordance with the characterizing part of patent claim 1 by that the first retaining element of the protective cuff is between the first end the air bellows and the first clamping ring.

Zweckmäßige Werkstoffe der Schutzmanschette sind in den Patentansprüchen 2 bis 6 genannt.Appropriate materials of the protective sleeve are in claims 2 to 6 called.

Die Erfindung wird nun anhand eines Ausführungsbeispieles unter Bezugnahme auf eine schematische Zeichnung erläutert, wobei diesbezüglich folgende Bezugsziffernliste gilt: 1 Luftfederanordnung
2 Druckbehälter (Luftfederdeckel)
3 Luftfederbalg mit Schlaufe (Rollfalte)
4 Luftfederkolben (Abrollkolben, Tauchkolben)
5 Außenführung
6 Schutzmanschette
7 erster Klemmring
The invention will now be explained using an exemplary embodiment with reference to a schematic drawing, in which respect the following list of reference numbers applies: 1 air spring arrangement
2 pressure vessels (air spring cover)
3 air bellows with loop (roll fold)
4 air spring pistons (rolling pistons, plunger pistons)
5 external guidance
6 protective sleeve
7 first clamping ring
