Description

Die vorliegende Erfindung betrifft einen Luftfederbalgträger zur Aufnahme des Luftfederbalgs an Nutzfahrzeugen wobei der Luftfederbalgträger aus faserverstärktem thermoplastischem Kunststoff besteht.The present invention relates to an air bellows carrier for receiving the air bellows on commercial vehicles, the air bellows carrier made of fiber-reinforced thermoplastic Plastic is made.

Moderne Lkw und deren Anhänger werden heute mit luftgefederten Fahrwerksystemen ausgestattet. Dadurch wird ein hoher Federungskomfort der Fahrzeuge sowie eine reduzierte Straßenbelastung erzielt. Grundsätzlich bestehen Luftfedern aus dem eigentlichen Luftbalg, einem unteren Befestigungskolben zur Befestigung auf dem Fahrwerksaggregat, einem Gummipuffer zur Fedenwegbegrenzung sowie einer oberen Befestigungsplatte zur Befestigung am Fahrzeugrahmen. Die obere Befestigungsplatte kann dabei über einen Luftfederbalgträger an dem Fahrzeugrahmen verbunden werden.Modern trucks and their trailers are today equipped with air suspension suspension systems. This will make a high suspension comfort of the vehicles and reduced road traffic achieved. in principle Air springs consist of the actual air bellows, a lower one Fastening piston for fastening on the chassis assembly, one Rubber buffer to limit the spring travel and an upper mounting plate for attachment to the vehicle frame. The top mounting plate can over an air bellows carrier be connected to the vehicle frame.

Luftfederbalgträger sind heute üblicherweise als Stahl- oder Aluminium-Schweißkonstruktion gefertigt und typischerweise als Winkel-Konsole ausgeführt.Air suspension bellows are commonly used today as Steel or aluminum welded construction manufactured and typically designed as an angle bracket.

Die steigenden Anforderungen an Gewichtseinsparung führen an die Grenzen des Potentials konventioneller Werkstoffe. In diesen Bereichen eröffnen neue, leistungsfähigere Werkstoffe neue Möglichkeiten der Produktentwicklung und -Optimierung.The increasing demands for weight saving to lead to the limits of the potential of conventional materials. In these Open areas new, more powerful Materials new opportunities product development and optimization.

Bei der Suche nach leichten, hochfesten und biegesteifen Materialien stößt man auf die Faser-Kunststoff-Verbunde. Durch geeignete Kombination eines Kunststoffs als Matrixwerkstoff mit hochfesten Fasern als Verstärkung gelangt man zu einem vielseitigen Verbundwerkstoff. Durch die Wahl eines geeigneten Verstärkungsaufbaus lassen sich den Anforderungen entsprechend maßgeschneiderte Werkstoff- und zugehörige Bauteileigenschaften einstellen.When looking for lightweight, high-strength and rigid materials are encountered the fiber-plastic composites. By a suitable combination of a Plastic as a matrix material with high-strength fibers as reinforcement one into a versatile composite material. By choosing a suitable one reinforcing structure can be tailored according to requirements associated Set component properties.

Luftfederbalgträger aus thermoplastischem Faser-Kunststoff-Verbunden übertreffen herkömmliche Stahl- oder Aluminiumkonsolen hinsichtlich ihrer Eignung, bieten darüber hinaus entscheidende Vorteile wie geringes Gewicht und vollständige Korrosionsbeständigkeit.Airbag bellows made of thermoplastic fiber-plastic composites surpass conventional Steel or aluminum consoles with regard to their suitability about that decisive advantages such as low weight and complete corrosion resistance.

Alle bisher bekannten Bauarten von Luftfederbalgträgern sind entweder zu aufwendig und damit zu kostenintensiv in der Herstellung, halten den Anforderungen bezüglich geringen Gewichtes, Korrosionsfreiheit oder mechanischer Beanspruchungen nicht stand und weisen optisch unzureichende Oberflächengüten auf.All previously known types of Luftfederbalgträgern are either too complex and therefore too expensive to manufacture, keep the requirements regarding low weight, no corrosion or mechanical stress stood and have optically inadequate surface qualities.

Der Erfindung liegt daher die Aufgabe zugrunde, Luftfederbalgträger derart weiterzubilden, dass die dem heutigen Stand der Technik entsprechenden Nachteile vermieden werden. Insbesondere soll ein Luftfederbalgträger mit geringem Eigengewicht und vollständiger Korrosionsbeständigkeit geschaffen werden, der zudem den mechanischen Beanspruchungen dauerhaft standhält und kostengünstig herzustellen ist.The invention is therefore the object based, air bellows carrier to be further developed in such a way that it corresponds to the current state of technology Disadvantages are avoided. In particular, an air bellows carrier is also intended low weight and more complete corrosion resistance be created, which also the mechanical stresses permanently withstands and inexpensive is to be produced.

Die Aufgabe wird gemäß einem ersten Aspekt der Erfindung bei dem eingangs genannten Luftfederbalgträger dadurch gelöst, dass der Luftfederbalgträger aus thermoplastischem Kunststoff in Kombination mit kontinuierlich faserverstärkten Kunststoff-Einlegeteilen besteht. Der thermoplastische Kunststoff kann zudem mit Füllstoffen versehen und/oder faserverstärkt sein.The task is carried out according to a first aspect of the invention in the air bellows carrier mentioned above solved, that the air bag carrier made of thermoplastic in combination with continuous fiber reinforced Plastic inserts exist. The thermoplastic can also with fillers provided and / or fiber reinforced his.

In einem weiteren Aspekt der Erfindung ist die Geometrie des Luftfederbalgträgers durch eine entsprechend kunststoffgerechte geometrische Ausgestaltung der Berührungsflächen zwischen Luftfederbalg und Luftfederbalgträger angepasst.In another aspect of the invention is the geometry of the air bag by a corresponding plastic-appropriate geometric design of the contact surfaces between Air suspension bellows and air suspension bellows adapted.

In einem weiteren Aspekt der Erfindung sind die Berührungsflächen zwischen Luftfederbalg und Luftfederbalgträger in der Oberflächenbeschaffenheit derart ausgestaltet, dass ein schonendes Abgleiten des Luftfederbalges erfolgen kann. Dies kann beispielsweise, aber nicht ausschließlich, durch Integration mit Elastomer beschichteten Oberflächen erfolgen.In another aspect of the invention are the interfaces between Air bag and air bag carrier in the surface condition in such a way designed that a gentle sliding of the air bellows can be done. This can be done, for example, but not exclusively Integration with surfaces coated with elastomer.

Die Befestigung des Luftfederbalgträgers, beispielsweise an Rahmenteile eines Fahrzeuges, erfolgt in einem weiteren Aspekt der Erfindung durch geeignete metallische Anschlusselemente.The attachment of the air bag carrier, for example on the frame parts of a vehicle takes place in a further aspect the invention by means of suitable metallic connecting elements.

Da thermoplastisch basierte Matrixsysteme zum Einsatz kommen kann der erfindungsgemäße Luftfederbalgträger beispielsweise durch mechanische Zerkleinerung und Wiedereinschmelzen sehr gut rezyklierf werden.Since thermoplastic based matrix systems for The bellows carrier according to the invention can be used, for example very good due to mechanical crushing and remelting be recyclable.

Die Erfindung wird im Folgenden anhand von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Zeichnungen näher beschrieben.The invention is explained below of embodiments described in more detail with reference to the accompanying drawings.
