Spannringbefestigung für einen Schlauchrollbalg einer LuftfederClamping ring fastening for a hose bellows of an air spring
Die Erfindung betrifft eine Luftfeder mit einem Schlauchrollbalg aus elastomerem Werkstoff, der mit mindestens einem Endabschnitt mittels eines radial plastisch verformten metallischen Spannrings an einem Anschlußteil dicht befestigt ist.The invention relates to an air spring with a hose bellows made of elastomeric material , which is tightly fastened to a connecting part with at least one end section by means of a radially plastically deformed metallic clamping ring.
Gegenüber den für höhere Belastungen in größeren Fahrzeugen mit Dichtwülsten und darin eingebetteten formsteifen Kernringen versehenen üblichen Luftfederbälgen bieten die hauptsächlich für den Einsatz in Personenkraftfahrzeugen vorgesehenen einfach-zylindrischen Schlauchrollbälge den Vorteil besonders kostengünstiger Herstellung mit der Möglichkeit, sie durch einfaches mechanisches Abtrennen von größeren Schlauchlängen zu gewinnen. Für die Befestigung der wulstlosen Endabschnitte des Schlauchrollbalges an den mit dem Fahrgestell bzw. der Fahrzeugachse verbundenen Anschlußteilen haben sich geschlossene, radial plastisch verformbare Spannringe bewährt. Durch das radiale Verformen der Spannringe werden die Endabschnitte der Schlauchrollbälge reibschlüssig verspannt. Eine derartige Spannringbefestigung eines Schlauchrollbalges ist aus der EP-A-O 151 696 bekannt.Compared to the usual air spring bellows with sealing beads and rigid core rings embedded in them for higher loads in larger vehicles, the single-cylindrical hose bellows, which are mainly intended for use in passenger vehicles, offer the advantage of being particularly cost-effective to manufacture and can be obtained by simply mechanically cutting off longer hose lengths. Closed, radially plastically deformable clamping rings have proven to be effective for fastening the beadless end sections of the hose bellows to the connecting parts connected to the chassis or the vehicle axle. The end sections of the hose bellows are clamped in a frictional manner by radially deforming the clamping rings. Such a clamping ring fastening of a hose bellows is known from EP-A-O 151 696.
Die Spannringe werden durch Absägen oder Abstechen von metallischen Rohren oder Rohrstücken gewonnen. Dabei wird der gewünschte Spannringdurchmesser durch Auswahl des entsprechenden Rohrdurchmessers bestimmt. Unterschiedliche Spannringdurchmesser erfordern daher die Vorhaltung einer entsprechenden Vielzahl von Rohren mit unterschiedlichen Durchmessern.The clamping rings are obtained by sawing or cutting off metal pipes or pipe sections. The desired clamping ring diameter is determined by selecting the corresponding pipe diameter. Different clamping ring diameters therefore require the provision of a corresponding number of pipes with different diameters.
Der Erfindung liegt die Aufgabe zugrunde, die Spannringbefestigung bei Luftfedern mit unterschiedlichem Durchmesser unter geringerem logistischem und konstruktivem Aufwand zu ermöglichen, wobei die Beschränkung auf eine begrenzte Durchmesseranzahl vermieden ist.The invention is based on the object of enabling the clamping ring fastening for air springs with different diameters with less logistical and structural effort, while avoiding the restriction to a limited number of diameters.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Spannring aus einem kreisförmig gebogenen Flachstahlabschnitt besteht, dessen aneinanderstoßende Enden stumpfgeschweißt sind.The object is achieved according to the invention in that the clamping ring consists of a circularly bent flat steel section, the abutting ends of which are butt-welded.
Flachstahl weist einen rechteckigen Querschnitt auf. Wird der Flachstahl zu einem Ring gerollt und anschließend an seinen Enden stumpf verschweißt, liegt ein geschlossener Spannring vor, der in üblicher Weise radial plastisch verformbar ist.Flat steel has a rectangular cross-section. If the flat steel is rolled into a ring and then butt-welded at the ends, a closed clamping ring is created that can be radially plastically deformed in the usual way.
Die Herstellung des Spannringes aus einem laufenden Flachstahl erlaubt die Anpassung auf beliebig große Durchmesser. Dadurch fällt das Vorhalten von unterschiedlich großen Halbzeugen, d.h. Rohren weg, was die Logistik in der Herstellung von Luftfedern wesentlich vereinfacht. Aus dem Halbzeug Flachstahl kann eine Vielzahl von verschiedenen Spannringdurchmessern gefertigt werden. Dadurch wird der Nachteil überwunden, daß bei der Spannringfertigung aus Rohrstücken die Verfügbarkeit nur bestimmter Rohrdurchmesser die Konstruktionen einschränkt. Bei der Fertigung von geschweißten Spannringen ist jeder beliebige Spannringdurchmesser realisierbar. Damit bestimmtThe manufacture of the clamping ring from a continuous flat steel allows adjustment to any diameter. This eliminates the need to stock semi-finished products of different sizes, i.e. pipes, which makes logistics in the manufacture of air springs much easier. A large number of different clamping ring diameters can be manufactured from the semi-finished flat steel. This overcomes the disadvantage that when manufacturing clamping rings from pipe sections, the availability of only certain pipe diameters limits the designs. When manufacturing welded clamping rings, any clamping ring diameter can be realized. This means that
• * &igr;• * &igr;
nicht mehr der Durchmesser der Halbzeuge Rohr die Konstruktion sondern der jeweilige Einsatzfall. Der jeweilige gewünschte Spannringdurchmesser wird durch entsprechendes Ablängen eines Flachstahlabschnittes realisierbar.It is no longer the diameter of the semi-finished pipe that determines the design but the specific application. The required clamping ring diameter can be achieved by cutting a flat steel section to the appropriate length.
