Abstract
Description
Die Erfindung betrifft eine Luftfeder, insbesondere für gefederte Radaufhängungen von Kraftfahrzeugfahrwerken, nach dem Oberbegriff des Hauptanspruchs.The The invention relates to an air spring, especially for sprung suspension of motor vehicle chassis, according to the preamble of the main claim.
Es ist bereits bekannt, einen Luftfederkolben mit einem Luftfederdeckel über einen zylindrischen Luftfederbalg aus elastomerem Werkstoff zu einer dichten Luftkammer zu verbinden. Bei einer so aufgebauten Luftfeder wälzt sich der Luftfederbalg unter Veränderung des Luftkammervolumens und unter Bildung einer Rollfalte mit seiner äußeren Mantelfläche am Luftfederkolben ab.It is already known, an air spring piston with an air spring cover over a cylindrical air bag made of elastomeric material to a tight Connect air chamber. With an air spring constructed in this way, it rolls the air bag under change of the air chamber volume and with the formation of a roll fold with its outer surface on the air spring piston from.
Besitzt eine solche Luftfeder mit Innenführung einen Rollbalg mit Kreuzlagenverstärkung, kann deren Wickelwinkel so gewählt werden, dass keine Außenführung für den Rollbalg notwendig ist. Besitzt jedoch der Rollbalg eine achsparallele Verstärkung oder eine axialnahe Kreuzlagenverstärkung, wird, zusätzlich zu einer Innenführung, eine Außenführung für den Rollbalg benötigt.has such an air spring with an inner guide a bellows with cross-layer reinforcement, its winding angle so chosen that no outer guide for the bellows necessary is. However, the bellows has an axially parallel reinforcement or an axial cross reinforcement, will, in addition to an inside tour, an external guide for the roller bellows needed.
Eine
Verwendung einer biegesteifen Außenführung, wie in
Deshalb ist es Aufgabe der Erfindung, eine Luftfeder bereitzustellen, die, bei optimalem Ansprechverhalten, die Achsauslegung nicht auf lineare Federki nematik einschränkt, sondern konstruktive Freiheiten zulässt durch Ermöglichung einer räumlichen Federkinematik.Therefore it is an object of the invention to provide an air spring which, with optimum response behavior, the axle design is not based on linear spring kinematics restricts but allows constructive freedom by enabling a spatial Spring kinematics.
Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The Task is inventively with the characteristic Features of claim 1 solved. Further refinements of the invention result from the subclaims.
Nach der Erfindung besteht eine Luftfeder, insbesondere für federnde Radaufhängungen von Kraftfahrzeugfahrwerken, aus einem, einen Luftfederkolben mit einem Luftfederdeckel zu einer dichten Luftkammer verbindenden zylindrischen Luftfederbalg aus elastomerem Werkstoff. Der Luftfederbalg wälzt sich unter Veränderung des Luftkammervolumens und unter Bildung einer Rollfalte mit seiner äußeren Mantelfläche luftfederkolbenseitig am Luftfederkolben und luftfederdeckelseitig in einem Führungszylinder ab. Die Erfindung ist dadurch gekennzeichnet, dass der Führungszylinder biegeweich ausgeführt ist.To The invention is an air spring, especially for resilient suspension of motor vehicle undercarriages, from one, with an air spring piston an air spring cover to a tight air chamber connecting cylindrical Air bag made of elastomeric material. The air bellows is rolling under change of the air chamber volume and with the formation of a roll fold with its outer lateral surface on the air spring piston side on the air spring piston and on the air spring cover side in a guide cylinder from. The invention is characterized in that the guide cylinder designed to be flexible is.
Eine solche biegeweiche, aber unter Innendruckbeaufschlagung in Umfangsrichtung unnachgiebig ausgeführte Außenführung hat den Vorteil, dass für den Konstrukteur bei der Achsauslegung größtmögliche konstruktive Freiheit bei optimalem Ansprechverhalten gegeben ist.A such flexible, but under internal pressure in the circumferential direction relentlessly executed Has outside guidance the advantage that for the designer with the greatest possible design freedom when designing the axis given optimal response.
Bevorzugte Ausführungsbeispiele der Erfindung sind dadurch gekennzeichnet, dass der Führungszylinder ein Elastomerschlauch ist, der mit Einlagen versehen ist, die diesen in Umfangsrichtung verstärken aber eine elastische Mindestauslenkung in Längsrichtung zulassen.preferred embodiments the invention are characterized in that the guide cylinder is an elastomer hose, which is provided with inserts that this reinforce in the circumferential direction but allow a minimum elastic deflection in the longitudinal direction.
Dabei können die Einlagen vorteilhafterweise umlaufende Ringe oder eine Spirale mit geringer Steigung sein und aus Fasern oder aus Federstahl bestehen. Ist der Führungszylinder ein innendrucksteifer Gewebeschlauch, hat das den Vorteil, dass die Luftfeder sehr einfach aufgebaut und herzustellen ist.there can the deposits advantageously encircling rings or a spiral be on a slight slope and consist of fibers or spring steel. Is the guide cylinder an inner pressure-resistant fabric hose has the advantage that the Air spring is very simple to build and manufacture.
Alternativ kann der Führungszylinder ein Elastomerschlauch in Form eines Faltenbalgs sein, dessen Falten zumindest bereichsweise mit Einlagen versehen sind, die diesen in Umfangsrichtung verstärken aber eine elastische Mindestauslenkung in Längsrichtung zulassen.alternative can the guide cylinder be an elastomer tube in the form of a bellows, the folds of which are at least partially provided with deposits that Reinforce circumferential direction but allow a minimum elastic deflection in the longitudinal direction.
Zur Kapselung des Rollbalges ist die einteilige Ausführung der elastischen Außenführung mit einem Faltenbalg besonders vorteilhaft. Dabei ist luftfederdeckelseitig eine gemeinsame Verkrimpung von Rollbalg und elastischer Außenführung möglich. Bei einer Außenführung aus Elastomer ist ferner eine sehr vorteilhafte Steinschlagresistenz gegeben.to Encapsulation of the rolling bellows is the one-piece design with the elastic outer guide a bellows particularly advantageous. The air spring cover is on the side joint crimping of the bellows and elastic outer guide possible. At a External tour Elastomer is also a very advantageous stone chip resistance given.
