Description

Die Erfindung betrifft ein Rad aus Faserverbundwerkstoff nach dem Oberbegriff des ersten Anspruchs und ein Verfahren zu dessen Herstellung.The invention relates to a wheel made of fiber composite material according to the preamble of the first claim and a method for its production.

Es ist bereits bekannt, Räder aus Faserverbundwerkstoff zu bauen, indem verschiedene Radeinzelteile vorgefertigt werden und danach das Rad aus diesen zusammen gesetzt wird.It is already known to build wheels made of fiber composite material by prefabricating various Radeinzelteile and then the wheel is made of these together.

Die DE 41 23 459 C1 beschreibt ein solches gebautes Rad mit einer Felge aus Kunststoff und einer Radschüssel aus Metall. Beide sind form-/kraft-/oder materialschlüssig zusammen gefügt. Ein solches Rad ist zwar leichter als ein komplett aus Metall gefertigtes Rad, allerdings begrenzt die massive Radschüssel aus Metall den Gewichtsvorteil.The DE 41 23 459 C1 describes such a built wheel with a plastic rim and a metal wheel disc. Both are form-fit / kraft- / or material-joined together. Although such a wheel is lighter than a completely made of metal wheel, but the massive metal wheel bowl limits the weight advantage.

Deshalb ist es Aufgabe der Erfindung, ein Rad aus Faserverbundwerkstoff mit Endlosfasersträngen bereitzustellen, das so beanspruchungsgerecht ausgebildet ist, dass die Radschüssel wenigstens teilweise aus Faserverbundwerkstoff aufgebaut werden kann, um eine weitere Gewichtsminimierung zu erhalten. Außerdem soll ein großserientaugliches Fertigungsverfahren zur Anwendung kommen.Therefore, it is an object of the invention to provide a wheel made of fiber composite material with endless fiber strands, which is designed to be stress-resistant, that the wheel disc can be at least partially constructed of fiber composite material in order to obtain a further weight minimization. In addition, a large-scale manufacturing process should be used.

Die Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung und ein Verfahren zur Herstellung ergeben sich aus den abhängigen Ansprüchen.The object is achieved with the features of claim 1. Further embodiments of the invention and a method for manufacturing resulting from the dependent claims.

Nach der Erfindung besteht ein einstückig in Form gewickeltes und danach gespritztes Rad aus Faserverbundwerkstoff mit Endlosfasersträngen, mindestens aus einer Felge und aus einem Radstern oder einer Radscheibe. Es ist dadurch gekennzeichnet, dass der Radstern oder die Radscheibe und/oder die Feige durch wenigstens einen Einleger aus Metall verstärkt sind.According to the invention there is an integrally wound in the form and then sprayed wheel made of fiber composite material with endless fiber strands, at least one rim and a wheel hub or a wheel disc. It is characterized in that the wheel center or the wheel disc and / or the fig are reinforced by at least one metal insert.

Bei einem Rad, das einstückig gefertigt wird und einen Einleger aus Metall besitzt, sind alle für die Gewichtsminimierung vorteilhaften Fertigungsmaßnahmen berücksichtigt. Es ist zur Herstellung kein nachträglicher Fügevorgang nötig, der Fügestellen als Schwachstellen im Faserverbund hinterlässt. Durch den metallischen Einleger im Radstern oder der Radscheibe, der mit dem Felgenbereich direkt verbunden ist, wird vorteilhafterweise ein duktiles Verhalten im Versagensfall erreicht, zum Beispiel bei einer Bordsteinanfahrt, und damit ein Wegbrechen von Faserverbundwerkstoff verhindert. Dadurch werden bessere mechanische Festigkeitswerte erreicht und das Gewicht kann aufgrund höherer Festigkeit vorteilhafterweise weiter reduziert werden.In a wheel, which is made in one piece and has a metal insert, all weight-minimizing manufacturing measures are taken into account. It is necessary for the production of no subsequent joining process, leaving joints as weak points in the fiber composite. Due to the metallic insert in the wheel center or the wheel disc, which is directly connected to the rim area, a ductile behavior is advantageously achieved in the event of a failure, for example in the event of a curb, and thus prevents the fiber composite from breaking away. As a result, better mechanical strength values are achieved and the weight can advantageously be further reduced due to higher strength.

Bei einer vorteilhaften Ausführung der Erfindung erstreckt sich der Einleger, den Radstern oder die Radscheibe verstärkend, in radialer Richtung gesehen, wenigstens über einen Bereich, von innen am Radstern oder an der Radscheibe bei den Ausnehmungen für die Radschrauben beginnend, bis in die Felge hinein zum Felgenhump hin. Dabei sind die Endlosfaserstränge vorteilhafterweise aus Aramid- und/oder Carbon- und/oder Glasfasern in eine Matrix aus duroplastischem oder thermoplastischem Polymerwerkstoff eingebettet.In an advantageous embodiment of the invention, the insert, the wheel or the wheel disc reinforcing extends, seen in the radial direction, at least over a range, starting from the inside of the wheel or on the wheel at the recesses for the wheel bolts, into the rim into the Felgenhump down. The continuous fiber strands are advantageously embedded in aramid and / or carbon and / or glass fibers in a matrix of thermosetting or thermoplastic polymer material.

Ein bevorzugtes Verfahren zum Herstellen eines Rades ist dadurch gekennzeichnet, dass in einem ersten Verfahrensschritt unidirektionale Endlosfaserstränge um einen drehbaren Formkern gewickelt werden, wobei der Einleger aus Metall als Halbzeug bereits beigefügt sein kann oder erst in einem zweiten Verfahrensschritt in einen Formhohlraum eines Spritzgieß-Werkzeugs eingelegt, mit diesem zum umwickelten Formkern hinzugefügt und im Weiteren mit umwickelt wird, wonach in einem dritten Verfahrensschritt das Werkzeug geschlossen wird und in den Formhohlraum flüssiger Polymerwerkstoff zur Erzeugung einer thermo- oder duroplastischen Matrix eingespritzt wird, womit der Einleger und die Endlosfaserstränge eingebettet werden. Dabei kann der flüssige Polymerwerkstoff kurze Aramid- und/oder Carbon- und/oder Glasfasern enthalten.A preferred method for producing a wheel is characterized in that unidirectional endless fiber strands are wound around a rotatable mandrel in a first method step, the metal insert may already be attached as semi-finished or inserted in a second step in a mold cavity of an injection mold , is added with this to the wrapped mandrel and further wrapped with, after which the tool is closed in a third step, and in the mold cavity liquid polymer material is injected to produce a thermosetting or thermosetting matrix, whereby the insert and the endless fiber strands are embedded. The liquid polymer material may contain short aramid and / or carbon and / or glass fibers.

Vorteilhafterweise bildet der Einleger während der Herstellung des Rades einen Teil der Form, ist somit Verstärkung, tragendes Bauteil und Form gleichzeitig, was die Herstellung des Rades mit einem Kern erst ermöglicht. Außerdem ist dieses Verfahren zur Herstellung als Spritzguss-Verfahren großserientauglich und verspricht eine preiswerte, schnelle Herstellung.Advantageously, the insert during manufacture of the wheel forms part of the mold, thus reinforcing, supporting member and form at the same time, which enables the production of the wheel with a core first. In addition, this process for production by injection molding is suitable for mass production and promises an inexpensive, rapid production.

Ein bevorzugtes Ausführungsbeispiel der Erfindung beschreibt die nachfolgende Beschreibung mit der zugehörigen Zeichnung. Die einzige Figur zeigt einen Querschnitt durch ein Spritzgusswerkzeug mit einem Rad gemäß der Erfindung.A preferred embodiment of the invention describes the following description with the accompanying drawings. The single figure shows a cross section through an injection molding tool with a wheel according to the invention.

Die Figur zeigt, schematisch gezeichnet, einen Querschnitt durch Oberform 1, Unterform 2, Losteile 3, Angussbuchse 4 und den Formhohlraum eines Spritzguss-Werkzeugs, gefüllt mit einem Rad 5 gemäß der Erfindung und hergestellt nach dem erfindungsgemäßen Verfahren.The figure shows, drawn schematically, a cross section through the upper mold 1 , Subform 2 , Loose parts 3 , Sprue bush 4 and the mold cavity of an injection molding tool filled with a wheel 5 according to the invention and prepared by the method according to the invention.

Man erkennt in der Kavität des Spritzguss-Werkzeugs das eingespritzte Rad 5 als ein in der äußeren Gestaltung wie üblich aufgebautes Rad eines Kraftfahrzeugs, beispielsweise Personenkraftwagens, bestehend aus einer Felge 6, mehreren Speichen 7 sowie Ausnehmungen 8 zur Aufnahme der Radschrauben. Dieses Rad 5 wird als Leichtbaurad aus faserverstärktem Kunststoffmaterial mit Einleger in einem Schuss nach dem erfindungsgemäßen Verfahren hergestellt. Demzufolge befindet sich in dem Radstern 10 mit den Speichen 7 ein nicht dargestellter Einleger aus Metall, eingelegt zwischen Oberform 1 und Unterform 2 als Halbzeug vor dem Schließen des Spritzguss-Werkzeugs. Der Einleger ist einstückig und befindet sich, in axialer Richtung gesehen, innerhalb des Radsterns 10, sich erstreckend, in radialer Richtung gesehen, über die Ausnehmungen 8 für Radschrauben bis in die Felge 6 hinein zum Felgenhump 9 hin.It can be seen in the cavity of the injection molding tool, the injected wheel 5 as a constructed as usual in the outer design wheel of a motor vehicle, such as passenger car, consisting of a rim 6 , several spokes 7 as well as recesses 8th for receiving the wheel bolts. This wheel 5 is manufactured as Leichtbaurad of fiber-reinforced plastic material with insert in a weft by the method according to the invention. As a result, is located in the wheel star 10 with the spokes 7 an unillustrated insert made of metal, inserted between the upper mold 1 and subform 2 as a semi-finished product before closing the injection molding tool. The insert is in one piece and, viewed in the axial direction, is located inside the wheel center 10 extending, viewed in the radial direction, over the recesses 8th for wheel bolts to the rim 6 into the rim hump 9 out.

Das Rad 5, des Weiteren bestehend aus Faserverbundwerkstoff mit Endlosfasersträngen aus Carbonfasern, ist einstückig in Form gewickelt und danach gespritzt. Das Verfahren zum Herstellen des Rades 5 zeichnet sich dadurch aus, dass in einem ersten Verfahrensschritt die nicht separat gezeichneten unidirektionalen Endlosfaserstränge um einen drehbaren Formkern, die Oberform 1, gewickelt werden. Der Einleger aus Metall wird als Halbzeug in einem zweiten Verfahrensschritt in den Formhohlraum des Spritzgieß-Werkzeugs eingelegt und mit diesem zum umwickelten Formkern hinzugefügt. Dann wird in einem dritten Verfahrensschritt das Spritzguss-Werkzeug geschlossen, das heißt die Oberform 1, die Unterform 2 und die Losteile 3 mit einer Teilung von 3X120 Winkelgrad werden dicht zusammengefügt, worauf in den Formhohlraum über die Angussbuchse 4 flüssiger thermoplastischer Polymerwerkstoff mit Überdruck aus einer Schmelze 11 eingespritzt wird, welcher danach aushärtet und womit der Einleger und die Endlosfaserstränge eingebettet werden. Der flüssige Polymerwerkstoff enthält kurze Carbonfasern.The wheel 5 , further consisting of fiber composite material with continuous fiber strands of carbon fibers, is integrally wound in the form and then sprayed. The method of manufacturing the wheel 5 is characterized by the fact that in a first process step, the non-separately drawn unidirectional endless fiber strands about a rotatable mandrel, the upper mold 1 to be wrapped. The insert made of metal is inserted as a semi-finished product in a second process step in the mold cavity of the injection mold and added with this to the wrapped mandrel. Then, in a third process step, the injection molding tool is closed, that is, the upper mold 1 , the subform 2 and the loose parts 3 with a pitch of 3X120 angular degrees are tightly joined, whereupon into the mold cavity via the sprue bushing 4 liquid thermoplastic polymer material with overpressure from a melt 11 is injected, which then hardens and with which the depositor and the endless fiber strands are embedded. The liquid polymer material contains short carbon fibers.

Die Endlosfaserstränge aus Carbonfasern werden im 1. Verfahrensschritt als bandförmiges Halbzeug zur Verstärkung der Felge 6 durch Drehen des Kerns um diesen, d. h. um die Oberform 1 gewickelt.The endless fiber strands of carbon fibers are in the 1st step as a band-shaped semi-finished product for reinforcing the rim 6 by turning the core around it, ie around the upper mold 1 wound.

Nach dem Aushärten des Rades 5 wird das Spritzguss-Werkzeug geöffnet und das Rad 5 entnommen. Das Spritzguss-Werkzeug kann deshalb so einfach ausgebildet werden, weil durch die Verwendung des Einlegers auch als Kern, notwendige Hinterschnitte, auf welche hier nicht näher eingegangen werden muss, beim Spritzguss-Werkzeug entfallen.After curing the wheel 5 The injection mold is opened and the wheel 5 taken. The injection molding tool can therefore be so easily formed, because through the use of the insert as a core, necessary undercuts, which need not be discussed here in detail, account for the injection molding tool.
