Description

Luftfederanordnung Air spring arrangement
Beschreibungdescription
Die Erfindung betrifft eine Luftfederanordnung, bestehend wenigstens aus:The invention relates to an air spring arrangement consisting at least of:
- einem Luftfederbalg aus elastomerem Werkstoff mit zwei Balgenden, der unter Bildung einer Schlaufe eine volumenelastische Luftkammer umschließt und insbesondere mit einer Außenführung versehen ist;- An air bellows made of elastomeric material with two bellows ends, which encloses a volume-elastic air chamber to form a loop and is in particular provided with an outer guide;
- einem Deckel und Kolben mit je einem Anschlussbereich für das jeweilige Balgende, wobei der Kolben eine Abrollfläche für die Schlaufe aufweist; sowie- A cover and piston, each with a connection area for the respective bellows end, the piston having a rolling surface for the loop; such as
- einer Manschette mit einem ersten Haltekragen, der gemeinsam mit dem korrespondierenden Balgende mittels eines Klemmringes am Deckel befestigt ist, und einem zweiten Haltekragen, der zumeist innerhalb des statischen Bereiches des Luftfederbalges und/oder an der Außenführung verankert ist.- A sleeve with a first holding collar, which is fastened together with the corresponding bellows end by means of a clamping ring on the cover, and a second holding collar, which is usually anchored within the static area of the air bellows and / or on the outer guide.
Eine gattungsgemäße Luftfederanordnung findet im Fahrzeugbau (PKW, Nutz- und Schienenfahrzeuge) eine breite Anwendung, wobei insbesondere auf die Druckschriften DE 298 23 508 U1, DE 100 50 028 A1 und 101 06 064 A1 verwiesen wird. In diesen Publikationen wird vorrangig die Technologie des Luftfederbalges mit Außenführung vorgestellt.A generic air spring arrangement is widely used in vehicle construction (passenger cars, utility vehicles and rail vehicles), reference being made in particular to documents DE 298 23 508 U1, DE 100 50 028 A1 and 101 06 064 A1. The main focus of these publications is on the technology of air bellows with external guidance.
Nach dem Gebrauchsmuster DE 298 23 508 U1 erfolgt die Anbindung der Außenführung am Deckel, die auch eine größere kardanische Auslenkung ermöglichen soll, mittels einer Manschette. Der erste Haltekragen der Manschette ist dabei zwischen einem Klemmring und einer zusätzlichen Schelle angeordnet. Ein derartiges Anbindungskonzept ist aufwendig und kostenintensiv. Vor allem ist hiermit eine aufwendige Positionierung des Klemmringes erforderlich.According to the utility model DE 298 23 508 U1, the outer guide is connected to the cover, which is also intended to allow greater gimbal deflection, by means of a sleeve. The first retaining collar of the cuff is arranged between a clamping ring and an additional clamp. Such a connection concept is complex and cost-intensive. Above all, a complex positioning of the clamping ring is required.
In der Offenlegungsschrift DE 101 06 064 A1 ist daher vorgeschlagen worden, den ersten Haltekragen der Manschette zwischen dem korrespondierenden Balgende und dem Klemmring anzuordnen. Auf diese Weise erfolgt zudem eine Aufdickung (Verstärkung) des Luftfederbalges innerhalb des Klemmbereiches, was im Hinblick auf seine Lebensdauer vorteilhaft ist.In the published patent application DE 101 06 064 A1 it has therefore been proposed to arrange the first retaining collar of the cuff between the corresponding bellows end and the clamping ring. In this way there is also a thickening (Reinforcement) of the air bellows within the clamping range, which is advantageous in terms of its service life.
Die Manschette kann zusätzlich eine Schutzfunktion ausüben. Darüber hinaus ist es möglich, die Manschette als Stützlager für eine zweite Schlaufe zu verwenden (DE 101 06 064 A1).The cuff can also perform a protective function. In addition, it is possible to use the cuff as a support bearing for a second loop (DE 101 06 064 A1).
Im Rahmen einer Weiterentwicklung besteht nun die Aufgabe der Erfindung darin, die Manschette so zu gestalten, dass die nachträgliche Balglagenüberprüfung innerhalb des Klemmbereiches möglich ist.As part of a further development, the object of the invention is to design the cuff so that the subsequent bellows position check is possible within the clamping area.
Gelöst wird diese Aufgabe gemäß Kennzeichen des Patentanspruches 1 dadurch, dass innerhalb des ersten Haltekragens der Manschette wenigstens eine Aussparung vorhanden ist, die von außen einen freien Blick auf das korrespondierende Balgende erlaubt, und zwar bezogen auf den verklemmten Zustand.This object is achieved in accordance with the characterizing part of patent claim 1 in that at least one recess is present within the first retaining collar of the cuff, which allows an unobstructed view of the corresponding bellows from the outside, in relation to the jammed state.
Zweckmäßige Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 4 genannt.Expedient embodiments of the invention are mentioned in claims 2 to 4.
Die Erfindung wird nun anhand eines Ausführungsbeispieles unter Bezugnahme auf schematische Zeichnungen erläutert. Es zeigen:The invention will now be explained using an exemplary embodiment with reference to schematic drawings. Show it:
Fig. 1 eine Luftfederanordnung mit den wesentlichen Grundbauteilen;1 shows an air spring arrangement with the essential basic components;
Fig. 2 eine Manschette mit Aussparungen;2 shows a cuff with recesses;
Fig. 3 eine Seitenansicht der Luftfederanordnung mit einer eingebauten Manschette gemäß Fig. 2;3 shows a side view of the air spring arrangement with a built-in sleeve according to FIG. 2;
Fig. 4 eine Schnittdarstellung der Luftfederanordnung gemäß Fig. 3.4 shows a sectional illustration of the air spring arrangement according to FIG. 3.
Fig. 1 zeigt eine Luftfederanordnung 1 mit den wesentlichen Grundbauteilen, nämlich Luftfederbalg 3, Deckel 2 mit Anbindungsmöglichkeiten für die Karosserie, Kolben 4 und Manschette 6. Der Deckel kann als Druckbehälter ausgebildet sein, gegebenenfalls in Verbindung mit einem Ventil (DE 198 19 642 A1). Der Luftfederblag 3 aus elastomerem Werkstoff ist zumeist mit einem eingebetteten Festigkeitsträger in Form eines Axialbalges (DE 36 43 073 A1 ) oder Kreuzlagenbalges (DE 29 04511 A1) versehen. Die beiden Balgenden sind innerhalb der beiden Anschlussbereiche an dem Deckel 2 bzw. Kolben 4 befestigt. Dadurch wird eine volumenelastische Luftkammer gebildet. Bei der Einfederung entsteht eine Schlaufe (dynamischer Bereich des Luftfederbalges), die an der Abrollfläche des Kolbens 4 entlang gleiten kann. Eine zusätzliche Außenführung 5 stützt den Luftfederbalg 3, was insbesondere bei Verwendung eines Axialbalges von Bedeutung ist.Fig. 1 shows an air spring arrangement 1 with the essential basic components, namely air bellows 3, cover 2 with connection options for the body, piston 4 and sleeve 6. The cover can be designed as a pressure vessel, optionally in connection with a valve (DE 198 19 642 A1 ). The air spring bracket 3 made of elastomeric material is usually provided with an embedded strength member in the form of an axial bellows (DE 36 43 073 A1) or cross-layer bellows (DE 29 04511 A1). The two bellows ends are fastened to the cover 2 or piston 4 within the two connection areas. This creates a volume-elastic air chamber. During the deflection, a loop is created (dynamic range of the air bellows), which can slide along the rolling surface of the piston 4. An additional outer guide 5 supports the air bellows 3, which is particularly important when using an axial bellows.
Fig. 2 zeigt nun Details der Manschette 6, die bei dem Ausführungsbeispiel gemäß Fig. 1 insbesondere als Schutzmanschette verwendet wird und aus einem elastomeren Werkstoff, einem thermoplastischen Elastomeren (TPE), einem thermoplastischen Kunststoff oder aus einem textilen Werkstoff besteht. Die Manschette umfasst dabei einen ersten Haltekragen 8 und zweiten Haltekragen 12, die jeweils endständig nach außen umgebördelt sind. Innerhalb des Außenrandes 13 des ersten Haltekragens sind nun umlaufend mehrere Aussparungen 9 vorhanden, die in etwa gleichen Abständen zueinander angeordnet sind.FIG. 2 now shows details of the cuff 6, which is used in the exemplary embodiment according to FIG. 1 in particular as a protective cuff and consists of an elastomeric material, a thermoplastic elastomer (TPE), a thermoplastic plastic or a textile material. The cuff comprises a first holding collar 8 and a second holding collar 12, each of which is flanged at the end. Within the outer edge 13 of the first retaining collar there are now a plurality of recesses 9 which are arranged at approximately equal distances from one another.
Die Fig. 3, 4 veranschaulichen das Zusammenwirken des Deckels 2, des Luftfederbalges 3, der Außenführung 5 und der Manschette 6. Der erste Haltekragen 8 ist hiernach gemeinsam mit dem korrespondierenden Balgende 11 mittels eines Klemmringes 7 innerhalb des Anschlussbereiches 10 am Deckel 2 befestigt. Mittels der Aussparungen 9 kann auch im verklemmten Zustand die Lage des Luftfederbalges 3 kontrolliert werden.3, 4 illustrate the interaction of the cover 2, the air bellows 3, the outer guide 5 and the sleeve 6. The first retaining collar 8 is then fastened together with the corresponding bellows end 11 by means of a clamping ring 7 within the connection area 10 on the cover 2. By means of the recesses 9, the position of the air bellows 3 can also be checked in the clamped state.
Der zweite Haltekragen 12 umgreift fest die Außenführung 5, wobei die Befestigung mittels Verklebung und/oder eines Klemmringes erfolgt. Hat die Luftfederanordnung keine Außenführung, so erfolgt die Verankerung des zweiten Haltekragens innerhalb des statischen Bereiches des Luftfederbalges. Gegebenenfalls kann der zweite Haltekragen so ausgebildet sein, dass er gleichzeitig die Funktion der Außenführung übernimmt (DE 2 064 751 A1, Fig. 2). BezugszeichenlisteThe second holding collar 12 tightly encompasses the outer guide 5, the attachment being carried out by means of gluing and / or a clamping ring. If the air spring arrangement has no outer guide, the second retaining collar is anchored within the static area of the air bellows. If necessary, the second retaining collar can be designed such that it simultaneously takes over the function of the external guide (DE 2 064 751 A1, Fig. 2). LIST OF REFERENCE NUMBERS
