Abstract
Description
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 zum Betreiben einer Luftfeder. Ferner betrifft sie eine Luftfederanordnung nach dem Oberbegriff des Patentanspruchs 2 zur Durchführung dieses Verfahrens.The The invention relates to a method according to the preamble of the claim 1 for operating an air spring. Furthermore, it relates to an air spring arrangement according to the preamble of claim 2 for carrying out this Process.
Luftfedern
werden in großem
Umfang zur Federung von Fahrzeugen eingesetzt, wo sie als tragende
Teile, insbesondere zwischen dem Fahrzeugaufbau (Karosserie und
Fahrgestell) und den Achsen, angeordnet werden. Ihre störungsfreie
Funktion ist eine Voraussetzung für den zuverlässigen Betrieb und
in besonderem Maße
auch für
die Verkehrssicherheit der Fahrzeuge. Da ein Defekt an einer Luftfeder
in aller Regel nur in einer Werkstatt behoben werden kann, ist ggf.
mit einem u.U. längeren
Ausfall des Fahrzeuges zu rechnen. Man ist daher bestrebt, die Verschleißanfälligkeit
von Luftfedern so zu vermindern, dass ihre Lebensdauer der voraussichtlichen
Gebrauchsdauer des gesamten Fahrzeuges entspricht (zum Stand der
Technik siehe z.B. die Druckschriften
Es ist bekannt, dass der Verschleiß von Luftfedern sich insbesondere dadurch erhöhen kann, dass ihr Rollbalg stärkeren Erwärmungen ausgesetzt ist, durch die das elastomere bzw. textile Rollbalgmaterial beschleunigt altert. Man hat daher bereits versucht, Erwärmungen der Rollbalgwandung dadurch entgegenzuwirken, dass man den Einfluss von Wärmestrahlung, die z.B. vom Motor oder von der Auspuffanlage ausgeht, mit Hilfe von Abschirmblechen verringert. Soweit der Wärmeeintrag in die Rollbalgwandung jedoch durch Konvektion und/oder Wärmeleitung erfolgt, erweisen sich Abschirmbleche und Reflektoren weitgehend als wirkungslos. Das gleiche gilt für Erwärmungen der Rollbalgwandung, die aus deren eigener Walkarbeit resultieren.It it is known that the wear of Air springs can increase in particular by the fact that their rolling bellows stronger warming is exposed, through which the elastomeric or textile Rollbalgmaterial accelerated aging. One has therefore already tried warming counteract the Rollbalgwandung by that the influence of heat radiation, the e.g. from the engine or the exhaust system, with the help of reduced by shielding. As far as the heat input into the Rollbalgwandung However, done by convection and / or conduction, prove Shielding and reflectors largely ineffective. The same applies warming the Rollbalgwandung resulting from their own flexing work.
Der Erfindung liegt daher die Aufgabe zugrunde, andere Maßnahmen aufzuzeigen, durch die die Temperatur der Rollbalgwandung unter allen im praktischen Betrieb auftretenden Bedingungen auf einen für die Rollbalgwandung unschädlichen Maximalwert begrenzt werden kann.Of the Invention is therefore the object of other measures show, by the temperature of the Rollbalgwandung below all conditions occurring in practical operation to one for the Rollbalgwandung harmless Maximum value can be limited.
Erfindungsgemäß wird diese Aufgabe zunächst durch ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 gelöst, das die im kennzeichnenden Teil dieses Anspruchs angegebenen Merkmale aufweist.According to the invention this Task first solved by a method according to the preamble of claim 1, the the features specified in the characterizing part of this claim having.
Ferner wird zur Lösung der genannten Aufgabe eine Luftfederanordnung nach dem Oberbegriff des Patentanspruchs 2 vorgeschlagen, die die im kennzeichnenden Teil dieses Anspruchs angegebenen Merkmale aufweist und die durch die kennzeichnenden Merkmale der Ansprüche 3 bis 5 vorteilhaft weitergebildet sein kann.Further becomes the solution the above object, an air spring assembly according to the preamble of Proposed patent claim 2, which in the characterizing part This claim has specified characteristics and by the Characteristic features of claims 3 to 5 advantageously developed can be.
Das erfindungsgemäße Verfahren hat den Vorteil, dass jeglicher schädlichen Erwärmung der Rollbalgwandung unverzüglich und effektiv durch einfaches Einschalten eines Kühlaggregates entgegengewirkt wird, das seinerseits unmittelbar die Innenluft des Rollbalges abkühlt. Sobald dann die Innenluft hinreichend abgekühlt ist, entzieht sie der angrenzenden Balgwand ihre überschüssige Wärme.The inventive method has the advantage that any harmful heating of the Rollbalgwandung immediately and effectively counteracted by simply switching on a cooling unit which in turn immediately cools the interior air of the rolling bellows. As soon as then the inside air has cooled sufficiently, it deprives the adjacent Bellows wall their excess heat.
