Abstract

A commercial vehicle axle air spring (1, 1', 1'', 1''') incorporates a supporting plate (2) forming the upper section and a piston (3) forming the lower section. The piston (3) is linked to a base plate (4) and buffer (5) unit. The two parts are linked by an elasticised bellows (6) incorporating travel-limiting belts (8, 13) fabricated in polyamid or polyester material, or galvanised steel wire (10, 12).

Description

Die Erfindung betrifft eine Luftfeder, umfassend eine Tragplatte als oberes Bauteil; einen Kolben als unteres Bauteil, wo bei der Kolben mit einer Bodenplatte versehen ist und zu dem einen Puffer aufweist; sowie einen Balg aus elastomerem Werkstoff, der die beiden Bauteile unter Verwendung entsprechender Befestigungsmittel miteinander verbindet.The invention relates to an air spring, comprising a support plate as an upper component; a piston as the lower component, where the piston is provided with a base plate and a buffer having; as well as a bellows made of elastomeric material, which the two components under Connects using appropriate fasteners.

Durch die einseitige Lagerung der Lkw-Achsen ist es möglich, daß z. B. bei der Einschiffung von Lkws starke Federwege auftreten, die über die maximale Luftfederauslenkung hinausgehen. Bei diesen Ausfedervorgängen können Kräfte auftreten, die zu einer Beschädigung der Luftfeder führen. Um einen Ausfall der Luftfeder zu vermeiden, werden von den Achsherstellern Fangseile vorgesehen, mit denen die Ausfederung begrenzt wird. Diese Fangseile werden zwischen den Fahrzeugrahmen und der Achse angeordnet.Due to the one-sided mounting of the truck axles, it is possible that, for. B. when embarking from Trucks have a lot of suspension travel that goes beyond the maximum air suspension deflection. At These rebound processes can cause forces that damage the air spring to lead. To prevent the air spring from failing, the axle manufacturers use safety ropes provided with which the rebound is limited. These safety ropes are between the Vehicle frame and the axle arranged.

Im Hinblick auf eine verbesserte Begrenzung der Ausfederung, verbunden mit einer längeren Lebensdauer der Luftfeder, wird nun erfindungsgemäß vorgeschlagen, daß das Fangsystem innerhalb der Luftfeder integriert ist.With regard to an improved limitation of the rebound, combined with a longer one Lifetime of the air spring, it is now proposed according to the invention that the catching system is integrated within the air spring.

Das Fangsystem kann ein Fang band sein, insbesondere auf der Basis von Kunststoff, insbesondere wiederum auf der Basis von Polyamid und/oder Polyester.The catching system can be a tether, especially based on plastic, again in particular based on polyamide and / or polyester.

Eine weitere vorteilhafte Möglichkeit ist, als Fangsystem ein Fangseil zu verwenden, insbesondere auf der Basis von Stahl, insbesondere wiederum auf der Basis von verzinktem Stahl.Another advantageous possibility is to use a safety rope as a safety system, in particular on the basis of steel, in particular in turn on the basis of galvanized Stole.

Im folgenden werden nun vier vorteilhafte Varianten (A, B, C, D) beschrieben.Four advantageous variants (A, B, C, D) are now described below.

  • A) Das Fang band ist durch einen an der Innenseite der Tragplatte befestigten Tunnel gezogen und verläuft dabei entlang der Innenwand des Balges, wobei die Fangbandenden im Bereich des Puffers befestigt sind, insbesondere in Form eines Kappen-Laschen-Systems.A) The tether is pulled through a tunnel attached to the inside of the support plate  and runs along the inner wall of the bellows, with the tether ends in the area of the buffer are attached, in particular in the form of a cap-tab system.
  • B) Das Fangseil ist an der Bodenplatte und der Tragplatte befestigt und verläuft dabei innerhalb des Kolbens, wobei die Befestigung des Fangseiles an der Tragplatte, insbesondere mittels zweier Laschen erfolgt.B) The safety rope is attached to the base plate and the support plate and runs inside of the piston, wherein the attachment of the safety rope to the support plate, in particular by means of two tabs.
  • C) Das Fangseil ist im unbelasteten Zustand spiralförmig im Bereich des Puffers abgelegt, wobei die Befestigung des Fangseiles an dem Kolben insbesondere mittels einer Halteklammer erfolgt, während die Befestigung des Fangseiles an der Tragplatte vorzugsweise mittels zweier Laschen geschieht.C) In the unloaded state, the safety rope is placed in a spiral in the area of the buffer, wherein the attachment of the safety rope to the piston in particular by means of a Retaining clip is done while attaching the safety rope to the support plate preferably done by means of two tabs.

Der besondere Vorteil dieser Variante ist das schnelle Ansprechverhalten der Luftfeder bei Befüllvorgängen.The particular advantage of this variant is the quick response of the air spring Filling processes.

  • D) Das Fangband ist durch einen an der Innenseite der Tragplatte befestigten Tunnel gezogen und verläuft dabei innerhalb des Kolbens zur Bodenplatte, wo die Fangbandenden befestigt sind.D) The tether is pulled through a tunnel attached to the inside of the support plate and runs inside the piston to the base plate, where the tether ends are attached are.

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:
