Abstract
Description
Die Erfindung betrifft eine Luftfederanordnung, bestehend wenigstens aus:
- - einem Luftfederbalg aus elastomerem Werkstoff mit zwei Balgenden, wobei der Luftfederbalg eine schräg verlaufende Schlaufe ausbildet; sowie
- - einem Deckel und Abrollkolben, die je einen Klemmsitz mit Befestigungsmitteln für das jeweilige Balgende aufweisen, wobei die Schlaufe an der Außenwand des Abrollkolbens entlang gleiten kann.
- - An air bellows made of elastomeric material with two bellows ends, the air bellows forming an oblique loop; such as
- - A lid and rolling piston, each having a clamp seat with fastening means for the respective bellows end, the loop being able to slide along the outer wall of the rolling piston.
Die gattungsgemäße Luftfederanordnung (Kurzbezeichnung "Luftfeder") findet im Fahrzeugbau (PKW, Nutz- und Schienenfahrzeuge) eine breite Anwendung. The generic air spring arrangement (short name "air spring") takes place in Vehicle construction (cars, commercial and rail vehicles) is widely used.
Zusätzliche Bauteile können Stoßdämpfer mit Dämpferlager, Außenführung für den Luftfederbalg und/oder Schutzmanschette sein. Ferner ist der Luftfederbalg zumeist mit einem eingebetteten Festigkeitsträger in Form eines Axialbalges (DE 36 43 073 A1) oder Kreuzlagenbalges (DE 29 04 522 A1) versehen. Hinsichtlich des diesbezüglichen Standes der Technik wird insbesondere auf folgende Druckschriften verwiesen: DE 36 24 296 C3, DE 36 31 610 A1, DE 197 53 637 A1 und EP 0 225 271 B1. Additional components can include shock absorbers with damper bearings, external guidance for the Air bag and / or protective sleeve. Furthermore, the air bag is mostly with an embedded reinforcement in the form of an axial bellows (DE 36 43 073 A1) or cross-layer bellows (DE 29 04 522 A1). Regarding The related art is particularly based on the following References: DE 36 24 296 C3, DE 36 31 610 A1, DE 197 53 637 A1 and EP 0 225 271 B1.
In der Offenlegungsschrift DE 199 07 656 A1 wird die Befestigung eines Luftfederbalges beschrieben, wobei neben dem üblichen Befestigungsmittel (Klemmring) zusätzlich ein Stützteil vorgesehen ist. Dadurch soll bei nicht wirkendem oder wesentlich abgesenktem Innendruck im Luftfederinnenraum die Bildung einer unerwünschten Falte im Luftfederbalg im Umgebungsbereich des Befestigungsmittels verhindert werden. In the published patent application DE 199 07 656 A1 the attachment of a Air bellows described, in addition to the usual fasteners (Clamping ring) an additional support part is provided. This is said to be inactive or significantly reduced internal pressure in the air spring interior to form a undesired fold in the air bellows in the area surrounding the fastener be prevented.
Die Aufgabe der Erfindung besteht nun darin, eine Luftfederanordnung bereitzustellen, bei der unter Einbezug der Entwicklung gemäß DE 199 07 656 A1 eine gezielte Erzeugung von Querkräften möglich ist. The object of the invention is now to provide an air spring arrangement, in which, taking into account the development according to DE 199 07 656 A1, a targeted Generation of lateral forces is possible.
Gelöst wird diese Aufgabe gemäß Kennzeichen des Patentanspruches 1 dadurch, dass im Bereich des Klemmsitzes des Abrollkolbens eine Stützhülse angeordnet ist, die asymmetrisch gestaltet ist, so dass der Luftfederbalg unterschiedlich große Bogenlängen überwinden muss, die zur Bildung der schrägen Schlaufe führen. This object is achieved in accordance with the characterizing part of patent claim 1 by that a support sleeve is arranged in the area of the clamping seat of the rolling piston, which is designed asymmetrically so that the air bellows have different sizes Must overcome arc lengths that lead to the formation of the oblique loop.
Zweckmäßige Ausgestaltungen der erfindungsgemäßen Luftfederanordnung sind in den Patentansprüchen 2 bis 11 genannt. Appropriate configurations of the air spring arrangement according to the invention are shown in the claims 2 to 11 called.
Die Erfindung wird nun anhand von Ausführungsbeispielen unter Bezugnahme auf schematische Zeichnungen erläutert. Es zeigen: The invention will now be described using exemplary embodiments with reference to schematic drawings explained. Show it:
Fig. 1 eine einfache Ausführung einer Stützhülse mit unterschiedlichem Höhenverlauf; . Figure 1 shows a simple embodiment of a support sleeve with varying height profile;
Fig. 2 eine Stützhülse mit unterschiedlichem Höhen- und Kantenverlauf. Fig. 2 shows a support sleeve with different heights and edges.
Fig. 1 zeigt einen Luftfederbalg 1 mit schräger Schlaufe 3 im Betriebszustand unter Druck, wobei die Schlaufe an der Außenwand 5 des Abrollkolbens 4 entlang gleiten kann. Der Luftfederbalg selbst ist zylindrisch geschnitten. Fig. 1 shows an air spring bellows 1 with oblique strap 3 in the operating state under pressure, wherein the loop on the outer wall 5 of the rolling piston 4 can slide along. The air bag itself is cut cylindrically.
Im Bereich des Klemmsitzes 6 des Abrollkolbens ist nun eine Stützhülse 8 als separates Bauteil (in Bezug auf den Abrollkolben) angeordnet, die asymmetrisch (d. h. nicht rotationssymmetrisch) gestaltet ist, so dass der Luftfederbalg unterschiedlich große Bogenlängen überwinden muss, die zur Bildung der schrägen Schlaufe 3 mit den beiden Tiefpunkten A und B führen. Die Asymmetrie der Stützhülse wird hier durch einen unterschiedlichen Höhenverlauf bewirkt. In the area of the clamping seat 6 of the roll-off piston, a support sleeve 8 is now arranged as a separate component (with respect to the roll-off piston), which is designed asymmetrically (ie not rotationally symmetrical), so that the air bellows has to overcome arc lengths of different sizes, which form the inclined loop 3 lead with the two low points A and B. The asymmetry of the support sleeve is brought about by a different height profile.
Nach Fig. 2 weist die Stützhülse 8' bei einem unterschiedlichen Höhenverlauf zusätzlich eine unterschiedliche Kontur 9 in Form eines unterschiedlichen Kantenverlaufs auf. According to FIG. 2, the support sleeve 8 'additionally has a different contour 9 in the form of a different edge profile with a different height profile.
Bei beiden Ausführungsbeispielen ist der Abrollkolben 4 im Gegensatz zur Stützhülse
im Wesentlichen rotationssymmetrisch ausgebildet.
