Abstract
Description
Die Erfindung betrifft eine Radfelge, insbesondere für Kraftfahrzeuge.The The invention relates to a wheel rim, in particular for motor vehicles.
Bekanntermaßen spielt bei der Entwicklung von Fahrzeugbauteilen die Reduzierung des Gewichts eine wesentliche Rolle, insbesondere im Hinblick auf den Kraftstoffverbrauch. Die Festigkeit und Widerstandsfähigkeit der Bauteile dürfen durch Gewichtsreduzierungen allerdings nicht beeinträchtigt sein. Insbesondere Radfelgen unterliegen mit zunehmender Leistungsfähigkeit der Fahrzeuge erhöhten Belastungen.As you know, plays in the development of vehicle components the reduction of weight an essential role, especially with regard to fuel consumption. The strength and resilience of the components but not be affected by weight reduction. In particular wheel rims are subject to increasing efficiency the vehicles increased loads.
Der Erfindung liegt die Aufgabe zugrunde, eine neue Radfelge zu schaffen, die bei geringem Materialeinsatz eine hohe Festigkeit und Widerstandsfähigkeit aufweist.Of the Invention has for its object to provide a new wheel rim, The high strength and resistance with low material usage having.
Die diese Aufgabe lösende Radfelge nach der Erfindung ist dadurch gekennzeichnet, dass sie ganz oder teilweise pressgehärtet ist.The solving this task Wheel rim according to the invention is characterized in that it completely or partially press-hardened is.
Durch die Presshärtung, d. h. durch Abkühlen in einem Presswerkzeug unter Pressdruck, lässt sich bei gegebener Materialmenge die Festigkeit und Widerstandsfähigkeit der Radfelge erheblich steigern. Darüber hinaus lassen sich Radfelgen mit hoher Maßgenauigkeit und damit geringer Unwucht herstellen, da bei dem Presshärtvorgang das Werkstück das Presswerkzeug ohne jede Rückfederung verlässt und damit genau die durch das Werkzeug vorgegebene Form aufweist. Bei herkömmlichen Härtungsverfahren würde sich die Radfelge infolge der Wärmeeinwirkung merklich verziehen. Große Festigkeit und Härte, insbesondere im Bereich des Reifenbetts, ver hindern Beschädigungen bei Reifendurchschlägen oder seitlichem Anfahren an Hindernisse.By the press hardening, d. H. by cooling in a pressing tool under pressing pressure, can be at a given amount of material the strength and resilience significantly increase the wheel rim. In addition, wheel rims can be with high dimensional accuracy and thus produce less imbalance, as in the press hardening process the workpiece the pressing tool leaves without any springback and so that exactly has the predetermined by the tool shape. at conventional curing process would become the wheel rim as a result of the heat noticeably forgiven. Great strength and hardness, especially in the area of the tire bed, ver prevent damage at tire punctures or sideways approaching obstacles.
Die Radfelge kann durch Warmumformung, insbesondere Warmtiefziehen hergestellt sein, wobei die Presshärtung vorzugsweise in einem Arbeitsgang mit dem Umformvorgang erfolgt. Die Teile können vorgeformt, d. h. in mehreren Stufen geformt sein, wobei in der letzten Stufe z. B. die Presshärtung erfolgt.The Wheel rim can be produced by hot forming, in particular thermoforming be, with the press hardening preferably takes place in one operation with the forming process. The parts can be preformed, d. H. be formed in several stages, with the last stage z. B. the press hardening he follows.
In einer besonders bevorzugten Ausführungsform der Erfindung weist die Felge Bereiche mit unterschiedlichem Presshärtungsgrad auf. D. h. die Presshärtung wird so gesteuert, dass sich in unterschiedlichen Bereichen unterschiedliche Härten und Festigkeiten ergeben. So kann gezielt an Stellen großer Belastung eine entsprechend große Festigkeit und Harte erreicht werden.In a particularly preferred embodiment The invention provides the rim regions with different degrees of compacting on. Ie. the press hardening is controlled so that different in different areas hardening and give strength. This allows targeted in places of great stress a correspondingly large Strength and hardness can be achieved.
Die Radfelge kann aus einem einzigen Blechmaterialstück oder mehreren solchen Materialstücken hergestellt sein. Vorzugsweise ist ein das Reifenbett bildende Außenring der Radfelge und ein mit der Radnabe verbindbarer Innenteil der Radfelge jeweils aus einem Materialstück hergestellt, wobei die Materialstücke, z. B. durch Verschweißen miteinander verbunden sind. Es können pressgehärtete und nicht pressgehärtete Teile miteinander verbunden sein.The Wheel rim can be made from a single piece of sheet metal or several such pieces of material be. Preferably, an outer ring forming the tire bed the wheel rim and a connectable to the hub inner part of the Wheel rim each made of a piece of material, wherein the pieces of material, for. B. by welding connected to each other. It can Press-hardened and not press-hardened Parts be connected.
Besteht nur der das Reifenbett bildende Außenring aus einem gesonderten Blechteil, so kann dieser Außenring vorteilhaft aus einem rohrförmigen Rohling geformt sein, wobei in einem Arbeitsgang mit der Formung aus dem Rohling eine Presshärtung erfolgen kann.Consists only the tire bed forming outer ring of a separate Sheet metal part, so this outer ring advantageous from a tubular blank be formed, in one operation with the shaping of the Blank a press hardening can be done.
Die die Radfelge bildenden Teile können durch Verschweißen, Löten, Kleben oder unter Verwendung von Schrauben oder Nieten aber auch durch Bördelung oder/und Verprägung miteinander verbunden sein, wobei die Teile insbesondere durch Warmbördeln bzw. Warmprägen bei gleichzeitiger Presshärtung verbunden werden. Eine Verbördelungsnaht oder Verprägungsnaht kann sich ringförmig entlang des das Reifenbett bildenden Außenteils erstrecken.The the wheel rim forming parts can through welding, Soldering, Gluing or using screws or rivets but also by flanging and / or embossing be connected to each other, wherein the parts in particular by hot crimping or hot stamping with simultaneous press hardening get connected. A flaring seam or stamped seam can be ring-shaped extend along the tire bed forming outer part.
In einer Ausführungsform der Erfindung weist der mit der Radnabe verbindbare Innenteil der Radfelge radiale Stege und dazwischen breite Ausnehmungen auf. Durch Presshärten, insbesondere der Stege, lässt sich ein stabiles Rad aus Stahlblech in Speichenoptik herstellen.In an embodiment The invention has the connectable to the wheel hub inner part of the wheel rim radial webs and wide recesses therebetween. By press hardening, especially the Footbridges, lets create a stable wheel made of sheet steel in spoke optics.
In einer bevorzugten Ausführungsform der Erfindung ist der das Reifenbett bildende Außenring der Radfelge am Außen- oder/und Innenrand umgebördelt und der Außenring weist in einem Randbereich einen im Querschnitt durch zwei Materiallagen gebildeten Abschnitt auf. Auf diese Weise lässt sich an den besonders belasteten Stellen des das Reifenbett bildenden Außenrings eine hohe Stabilität erzielen. Entsprechend widerstandsfähig ist die Radfelge gegen Durchschlagen und seitliches Anschlagen.In a preferred embodiment the invention of the tire bed forming outer ring of the wheel rim on the outside and / or Bordered inside edge and the outer ring has an edge region formed in cross section by two layers of material Section on. That way at the particularly stressed areas of the tire bed forming outer ring a high stability achieve. Accordingly, the wheel rim is resistant to Penetration and lateral striking.
Eine der beiden Materiallagen kann bis an den Innenteil der Radfelge heranreichen. Bei einstückiger Herstellung der Radfelge geht die dem Reifenbett abgewandte Materiallage dann einstückig in das Innenteil über.A The two material layers can be up to the inner part of the wheel rim come close. In one piece Production of the wheel rim is the material bed facing away from the tire bed then in one piece in the inner part over.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen und der beiliegenden, sich auf diese Ausführungsbeispiele beziehenden Zeichnungen näher erläutert.
