Description

Rad, insbesondere Leichtmetallrad Wheel, especially light alloy wheel
BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft ein Rad, insbesondere ein Leichtmetallrad für Kraftfahrzeuge, gemäß Oberbegriff des Anspruchs 1.The invention relates to a wheel, in particular a light alloy wheel for motor vehicles, according to the preamble of claim 1.
Derartige Räder erfreuen sich speziell in der Ausführung alsSuch wheels are particularly popular in the design as
Leichtmetallräder sehr großer Beliebtheit, da sich neben einem gesteigerten ästhetischen Gesamterscheinungsbild des Kraftfahrzeugs weitere technische Vorteile erzielen lassen.Alloy wheels are very popular because, in addition to an increased overall aesthetic appearance of the motor vehicle, other technical advantages can be achieved.
Ganz allgemein geht die Tendenz dahin, das Gewicht des Rades soweit wie möglich zu reduzieren. Dies ist ein weiterer Grund für die zunehmende Verbreitung der Leichtmetallräder. Die Gewichtsersparnis gegenüber herkömmlichen Stahlrädern fällt jedoch häufig nicht sehr hoch aus, da die verwendeten Leichtme- talllegierungen meist nicht die Festigkeit von Stahl aufweisen. Solche Räder müssen deshalb mit größeren Wanddicken ausgeführt werden, wodurch der Gewichtsvorteil zum Teil wieder verloren geht .In general, there is a tendency to reduce the weight of the wheel as much as possible. This is another reason for the increasing spread of light alloy wheels. However, the weight saving compared to conventional steel wheels is often not very high, since the light metal alloys used do not usually have the strength of steel. Such wheels must therefore be made with larger wall thicknesses, whereby the weight advantage is partially lost again.
Aus der WO 01/17799A1 ist ein Rad bekannt, das durch einen speziellen Aufbau eine weitere Gewichtsreduzierung ermöglicht.A wheel is known from WO 01 / 17799A1, which enables a further weight reduction due to a special structure.
Dieses bekannte Rad weist eine Radfelge auf, die mit einem Felgenaußenbett und einem Felgeninnenbett versehen ist. Das Felgenaußenbett dient zusammen mit einem Profilsegment alsThis known wheel has a wheel rim which is provided with a rim outer bed and a rim inner bed. The outer rim bed serves together with a profile segment
Sitz für einen Reifen, unterhalb des Profilsegments existiert ein Hohlraum, so dass ein geschlossenes Hohlprofil entsteht, das zu gewünschten Festigkeitserhöhung führt. Das Profilseg- ment besteht aus separat gefertigten Halbschalen, die beispielsweise aus Kunststoff gefertigt sind, wodurch sich ein leichtes Rad aufbauen lässt, das besonders in gefährdeten Be- reichen eine hohe Festigkeit aufweist.Seat for a tire, there is a cavity below the tread segment so that a closed hollow profile is created, which leads to the desired increase in strength. The profile segment consists of separately manufactured half-shells, which are made of plastic, for example, which means that a lightweight wheel can be built that is particularly strong in hazardous areas.
Nachteilig hierbei ist jedoch der relativ hohe fertigungstechnische Aufwand. Das Profilsegment muss, wenn es als Halbschale ausgebildet ist, separat hergestellt und anschließend durch Kleben oder Schweißen mit der Felge verbunden werden,However, the relatively high manufacturing outlay is disadvantageous here. If it is designed as a half-shell, the profile segment must be manufactured separately and then connected to the rim by gluing or welding,
Der Erfindung lag deshalb das Problem zugrunde, ein Rad der eingangs genannten Art dahingehend zu verbessern, dass der fertigungstechnische Aufwand reduziert wird.The invention was therefore based on the problem of improving a wheel of the type mentioned at the outset in such a way that the manufacturing outlay is reduced.
Gelöst wird dieses Problem durch ein Rad mit den Merkmalen des Anspruchs 1.This problem is solved by a wheel with the features of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind durch die Merkmale der ünteransprüche angegeben.Advantageous embodiments of the invention are specified by the features of the subclaims.
Die Erfindung basiert auf der Idee, den Kunststoff unmittelbar am Rad anzufor en. Hierdurch gelingt es, die Gewichts- und Festigkeitsvorteile des bekannten Rades, bei denen das Felgen- außenbett zumindest abschnittsweise durch vorge ertigte Profilsegmente gebildet ist, beizubehalten, den Fertigungsaufwand jedoch erheblich zu reduzieren. Durch diese Konzeption können etablierte Fertigungsverfahren, wie beispielsweise das Spritzgießverfahren, zur Anwendung kommen.The invention is based on the idea of requesting the plastic directly on the wheel. In this way, it is possible to maintain the weight and strength advantages of the known wheel, in which the rim outer bed is formed at least in sections by pre-made profile segments, but to reduce the manufacturing effort considerably. With this concept, established manufacturing processes, such as the injection molding process, can be used.
Besondere Vorteile ergeben sich speziell bei denjenigen Rädern, bei denen der Radstern Speichen aufweist. Die SpeichenSpecial advantages arise especially for those wheels in which the wheel star has spokes. The spokes
BESTÄTIGUN S OP können aus Gründen der Gewichtsersparnis mit Speichenhohlräumen versehen werden, die dann mit Kunststoff ausgefüllt werden. Der hierdurch entstehende KunstStoffkern wird radial so weit aus dem unmittelbaren Bereich des Radsterns herausge- führt, dass er nach oben hin in den Bereich des Felgenaußen- betts hineingeführt wird und unmittelbar als Reifensitz dient. Somit lassen sich derartige Räder kostengünstig herstellen, wobei hervorragende Festigkeitswerte erzielbar sind. Insbesondere können die Wanddicken der Speichen weiter reduziert wer- den, wodurch sich eine erhebliche Gewichtsreduzierung bei gleichbleibender Festigkeit erzielen lässt.CONFIRMATION S OP can be provided with spoke cavities to save weight, which are then filled with plastic. The resulting plastic core is led radially out of the immediate area of the wheel spider so that it is led upwards into the area of the outer rim bed and serves directly as a tire seat. Such wheels can thus be produced inexpensively, and excellent strength values can be achieved. In particular, the wall thicknesses of the spokes can be reduced further, as a result of which a considerable weight reduction with constant strength can be achieved.
Besondere Vorteile ergeben sich bei der Verwendung von. geschäumten Kunststoffen, mit denen sich zusätzlich eine weitere Gewichtsersparnis erzielen lässt. Diese kann gegenüber bisherigen Konstruktionen mindestens 1 bis 2 kg pro Rad betragen.There are special advantages when using. foamed plastics, with which additional weight savings can be achieved. Compared to previous designs, this can be at least 1 to 2 kg per wheel.
Besonders vorteilhaft ist es, wenn der geschäumte Kunststoff an seiner Oberfläche eine Haut aufweist, die somit einen glat- ten und optimalen Reifensitz gewährlei-stet und insbesondere auch ohne zusätzliche Maßnahmen einen luftdichten Abschluss zum Reifen ermöglicht.It is particularly advantageous if the foamed plastic has a skin on its surface, which thus ensures a smooth and optimal tire fit and, in particular, also enables an airtight seal to mature without additional measures.
Wenn der Kunststoff ein verstärkter, insbesondere faserver- stärkter Kunststoff ist, beispielsweise ein glasfaser- oder kohlenstofffaserverstärkter Kunststoff, können die geforderten Festigkeitseigenschaften des Rades besonders einfach und zugleich Gewicht sparend erreicht werden.If the plastic is a reinforced, in particular fiber-reinforced plastic, for example a glass fiber or carbon fiber reinforced plastic, the required strength properties of the wheel can be achieved particularly easily and at the same time saving weight.

Kunststoffe besonders Polyamid oder ein Polycarbonat . Machfolgend wird ein Ausführungsb'eispiel anhand der Figur näher erläutert.Plastics especially polyamide or a polycarbonate. Mach Following is a Ausführungsb 'EXAMPLE explained in more detail with reference to FIG.
Sie zeigt einen Halbschnitt durch ein erfindungsgemäßes Rad.It shows a half section through a wheel according to the invention.
Ein Rad 1 ist in an sich bekannter Weise aus einer Radfelge 10 und einem Radstern 20 aufgebaut.A wheel 1 is constructed in a manner known per se from a wheel rim 10 and a wheel star 20.
Die Radfelge 10 weist ein Felgeninnenbett 16 und ein Felgenau- ßenbett 14 auf. Diese gehen axial auswärts jeweils in ein Felgeninnenhorn 18 und ein Felgenaußenhorn 12 über. Zwischen dem Felgeninnenhorn 18 und dem Felgenaußenhorn 12 wird ein Reifen 50 gehalten, der auf dem Felgeninnenbett 16 und dem Felgenaußenbett 14 sitzt und seitlich am Felgeninnenhorn 18 und Fel- genaußenhorn 12 anliegt.The wheel rim 10 has an inner rim bed 16 and an outer rim bed 14. These merge axially outward into a rim flange 18 and a rim flange 12. A tire 50 is held between the inner rim 18 and the outer rim 12, which sits on the inner rim 16 and the outer rim 14 and rests laterally on the inner rim 18 and the outer rim 12.
Die Radfelge 10 geht in den Radstern 20 über, der eine Vielzahl von Speichen 22 aufweist. Die Speichen 22 sind aus Gründen der Gewichtsersparnis als Hohlspeichen ausgeführt und wei- sen jeweils einen Speichenhohlraum 24 auf.The wheel rim 10 merges into the wheel star 20, which has a plurality of spokes 22. To save weight, the spokes 22 are designed as hollow spokes and each have a spoke cavity 24.
Die Oberfläche des Kunststoffschaums bildet eine Haut 32 aus und bietet somit einen gl tten und optimalen Sitz für den Reifen 50. Durch das Ausfüllen des' Hohlraums 24 der Speiche 22 mit dem Kunststoff kann die Festigkeit der Speiche 22 gesteigert werden, was insbesondere bei Leichtmetallrädern von großem Vorteil ist, da dadurch ihr Impact-Verhalten verbessert. Somit wird mit dem erfindungsgemäßen Rad 1 die Gefahr einer Beschädigung beim Überfahren einer Bordsteinkante oder eines Schlagloches reduziert. The surface of the plastic foam forms a skin 32 and thus offers a smooth and optimal fit for the tire 50. By filling the ' cavity 24 of the spoke 22 with the plastic, the strength of the spoke 22 can be increased, which is particularly the case with light metal wheels is a big advantage because it improves their impact behavior. Thus, the risk of damage when driving over a curb or a pothole is reduced with the wheel 1 according to the invention.
