Die Erfindung betrifft weiterhin ein Verfahren zu deren Herstellung nach dem Oberbegriff des Anspruchs 6.The The invention relates to a wheel rim made of fiber composite material The preamble of claim 1. The invention further relates a method for their preparation according to the preamble of the claim 6th
Die Radfelge besteht aus Felgennabe, Felgenstern bzw. Speichen oder Felgenscheibe und Felgenbett bzw. Felgenkranz. Das Felgenbett trägt beim luftbereiften Rad den Luftreifen. Es hat dann einen etwa u-förmigen, in radialer Richtung nach außen offenen Querschnitt; die beiden Seitenwände enden als Felgenhorn. Die Felgenscheibe und die Felgennabe bilden die radiale Tragstruktur für das Felgenbett und sind über einen Radflansch mit der Fahrzeugachse verbunden. Die Felgenscheibe kann Löcher aufweisen bzw. nur aus einzelnen Speichen bestehen. In ihrem Zentrum befindet sich die Felgennabe, die eine Anbindungsfläche für den Radflansch darstellt. Die Anbindungsfläche besitzt eine kreisförmige Öffnung, welche zur Radzentrierung dient, und mehrere um diese Öffnung angeordnete kleinere Löcher für die Befestigung der Radfelge auf dem Radflansch.The Wheel rim consists of wheel hub, rim star or spokes or Rim wheel and rim bed or rim. The rim bed is worn in pneumatic Wheel the pneumatic tire. It then has an approximately U-shaped, in the radial direction outward open cross section; the two side walls end as a rim flange. The Rim wheel and the rim hub form the radial support structure for the Rim bed and are over a wheel flange connected to the vehicle axle. The rim disk can holes have or only consist of individual spokes. In her center is the rim hub, which represents a connection surface for the wheel flange. The connection area has a circular opening, which serves for Radzentrierung, and several arranged around this opening smaller holes for the Fixing the wheel rim on the wheel flange.
Die Forschung und Entwicklung in der Automobilindustrie ist wesentlich vom Streben nach Massereduktion geprägt, um das Leistungsgewicht sowie den Fahrkomfort der Fahrzeuge zu verbessern. Diesbezüglich bieten endlosfaserverstärkte Verbundwerkstoffe als Konstruktionsmaterialien ein enormes noch nicht ausgeschöpftes Leichtbaupotenzial. Der Einsatz dieser Materialien gelingt derzeit besonders gut im Bereich der Karosseriebeplankung, wie etwa in Dach- und Türstrukturen aus Faserverbundwerkstoffen (FVW). Im Bereich der strukturell, medial und thermisch hoch belasteten Fahrzeugbaugruppen werden jedoch endlosfaserverstärkte Verbundwerkstoffe bisher kaum eingesetzt.The Research and development in the automotive industry is essential characterized by the pursuit of mass reduction to the power to weight ratio and to improve the ride comfort of the vehicles. Offer in this regard continuous fiber reinforced Composites as construction materials a tremendous yet not exhausted Lightweight potential. The use of these materials is currently successful particularly well in the area of body paneling, such as roofing and door structures made of fiber composite materials (FVW). In the field of structural, medial and thermally highly loaded vehicle assemblies, however, become continuous fiber reinforced composites hardly used until now.
Radfelgen sind entsprechend hoch belastete Bauteile und werden derzeit üblicherweise in Metallbauweise ausgeführt. Aufgrund ihrer Funktion stellt die Radfelge eine ungefederte und rotierende Masse am Fahrzeug dar und ist somit hinsichtlich einer Massereduktion besonders prädestiniert. Aufgrund der angestrebten bauteilbezogenen Massereduktion von mindestens 30% zur Metallbauweise und einem neuartigen, hocheffizienten Herstellungsprozess besitzt die hier beschriebene Erfindung der Erzeugung von Radfelgen aus endlosfaserverstärkten Verbundwerkstoffen ein extrem großes Potenzial für den Automobilbau.wheel rims are correspondingly highly loaded components and are currently becoming commonplace executed in metal construction. Due to its function, the wheel rim represents an unsprung and rotating mass on the vehicle and is thus in terms of a Mass reduction particularly predestined. Due to the targeted component-related mass reduction of at least 30% to the metal construction and a new, highly efficient manufacturing process The invention described here has the production of wheel rims made of endless fiber reinforced Composites an extremely great potential for the automotive industry.
Der Stand der Technik umfasst derzeit eine große Vielfalt verschiedenster metallischer Radfelgenkonstruktionen welche mit gängigen Verarbeitungsprozessen wie z.B. dem Gesenkschmieden, dem Druckguss bzw. der Zerspanung oder dem Umformen hergestellt werden.Of the The state of the art currently includes a wide variety of different types Metallic wheel rim constructions with common processing processes such as. die forging, die casting or machining or forming.
Endlosfaserverstärkte Felgenstrukturen
sind derzeit in Faserverbundbauweise nur mittels verschiedenster
Fügetechniken
herstellbar. Dabei müssen
entweder einzelne konsolidierte Komponenten der Felge wie zum Beispiel
das Felgenbett und der Felgenstern (Speichen) miteinander gefügt werden oder
die Faserpreform besteht aus mehreren, beispielsweise vernähten oder
verklebten Faserhalbzeugen (vgl.
Metallische Felgenkonstruktionen sind zwar wirtschaftlich herstellbar, besitzen jedoch nur ein moderates Leistungsgewicht.Metallic Rim constructions are indeed economical to produce, own but only a moderate power to weight ratio.
Radfelgen aus Faserverbundwerkstoffen weisen ein wesentlich besseres Leistungsgewicht auf, können aber zur Zeit nur mit Hilfe von Fügeverfahren hergestellt werden. Die beim Fügen immer notwendigen Fügeelemente (Nähfäden, Schrauben, Nieten) reduzieren das Leistungsgewicht auf Grund ihrer zusätzlichen Masse. Die Fügestellen bilden immer eine Unterbrechung des Kraftflusses und verursachen dadurch an den Fügestellen einen erhöhten Materialeinsatz (z.B. Überlappungen oder lokale Wandstärkenaufdickungen).wheel rims made of fiber composite materials have a much better power to weight, can but at present only with the help of joining processes. The joining always necessary joining elements (Sewing threads, screws, rivets) reduce the power-to-weight ratio due to their extra weight Dimensions. The joints always make an interruption of the power flow and cause thereby at the joints an increased use of materials (e.g., overlaps or local wall thickness thickening).
Aufgrund der benötigten Maschinen bzw. Arbeitskräfte können Felgen aus Faserverbund im Moment nur schlecht automatisierbar und nur mit einem hohen technischen bzw. wirtschaftlichen Aufwand hergestellt werden. Insbesondere die meist aufwendigen Fügeprozessschritte stellen einen hohen Kostenfaktor am Gesamtbauteil dar.by virtue of the needed Machines or workers can Rims made of fiber composite at the moment only poorly automated and produced only with a high technical or economic effort become. In particular, the most complex joining process steps make one high cost factor on the overall component.
Daher besteht derzeit keine Möglichkeit Faserverbundfelgen in vergleichbarer Effizienz zu metallischen Felgenkonstruktionen herzustellen.Therefore there is currently no possibility Fiber composite rims in comparable efficiency to metallic rim designs manufacture.
Die Aufgabe der Erfindung besteht darin, eine Radfelge sowie ein Verfahren zur wirtschaftlich effizienten Herstellung der Radstruktur aus endlosfaserverstärkten Verbundwerkstoffen ohne Verwendung zusätzlicher Fügeelemente oder Verbindungsstellen anzugeben.The The object of the invention is a wheel rim and a method for the economically efficient production of the wheel structure from continuous fiber reinforced composite materials without the use of additional joining elements or connecting points.
Erfindungsgemäß wird die Aufgabe durch eine Radfelge mit den im Anspruch 1 genannten Merkmalen gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand von abhängigen Unteransprüchen.According to the invention Task by a wheel rim with the features mentioned in claim 1 solved. Advantageous embodiments are the subject of dependent subclaims.
Gemäß Anspruch 1 wird die Aufgabe durch den Einsatz von geflochtenen endlosen Fasern zur Erzeugung der textilen Preform gelöst. Dabei sind die Fasern in Form eines Flechtschlauches angeordnet. Dieser Flechtschlauch kann durch Überflechten eines Hilfskerns erzeugt werden oder als Halbzeug vorliegen. Mit Flechtschläuchen kann die Radgeometrie sehr gut nachgebildet werden.According to claim 1, the object is achieved by the use of braided endless fibers to produce the textile preform. Here are the Fibers arranged in the form of a braided hose. This braided hose can be produced by braiding over an auxiliary core or be present as a semi-finished product. With braided hoses, the wheel geometry can be simulated very well.
Flechtschläuche sind Stand der Technik und kommerziell in verschiedensten Ausführungen verfügbar. Durch die speziellen Eigenschaften von Faserflechtschläuchen lassen sich Querschnittsänderungen leicht realisieren. Die Besonderheit des schlauchförmigen Geflechtes liegt in seiner extremen Drapierfähigkeit, wodurch es sich für den vorliegenden Einsatzfall in besonderer Weise anbietet. Ein Flechtschlauch kann eine typische Durchmesseränderung von 700% realisieren, ohne seine strukturelle Integrität zu verlieren. Daraus ergeben sich die erreichbaren Verhältnisse zwischen Rohr- und Scheibendimension der Felge. Hinsichtlich der absoluten Bauteilabmessungen sind keine Beschränkungen vorhanden.Braided tubes are State of the art and commercially available in various designs available. Due to the special properties of fiber braided sleeving itself cross-sectional changes easy to realize. The peculiarity of the tubular braid lies in its extreme drape ability, which makes it suitable for the present Application offers in a special way. A braided hose can a typical diameter change 700% without losing its structural integrity. This results in the achievable ratios between pipe and Slice dimension of the rim. With regard to the absolute component dimensions There are no restrictions.
Die Aufgabe wird weiterhin durch ein Verfahren zur Herstellung eines Rades mit den im Anspruch 6 genannten Merkmalen gelöst. Vorteilhafte Varianten des Verfahrens sind in den abhängigen Unteransprüchen genannt.The Task will continue by a method for producing a Rades solved with the features mentioned in claim 6. advantageous Variants of the method are mentioned in the dependent subclaims.
Zur Erzeugung der textilen Preform wird ein Stück Flechtschlauch in mehreren Schritten gleichzeitig aufgeweitet und umgestülpt bis es eine Felgenform angenommen hat. Das Umstülpen erfolgt dabei vorteilhaft über einen Hilfskern. Er verbleibt dauerhaft in der Felgenstruktur und kann aus verschiedensten vollen oder geschäumten Werkstoffen bestehen. Durch diesen Hilfskern wird eine Vorfixierung der textilen Preform erreicht. Vorteilhaft wird ein Kunststoffschaumkern verwendet, der im Sinne der Sandwichbauweise die Felgenstruktur zusätzlich versteift. Anstelle des Hilfskerns kann der Flechtschlauch auch über mehrere Ringe gestülpt werden, welche dann über ein entsprechendes Werkzeug zueinander fixiert werden.to Production of the textile preform becomes a piece of braided hose in several Steps widened at the same time and everted until it's a rim shape has accepted. The eversion takes place advantageously over an auxiliary kernel. It remains permanently in the rim structure and can consist of a variety of full or foamed materials. By This auxiliary core prefixing of the textile preform is achieved. Advantageously, a plastic foam core is used, in the sense The sandwich construction additionally stiffens the rim structure. Instead of of the auxiliary core, the braided hose can also be put over several rings, which then over a corresponding tool are fixed to each other.
Um eine mehrlagige Preform zu erzeugen, können entweder mehrere kurze Schlauchstücke ineinander geschoben werden und dann nach dem oben beschrieben Prinzip gestülpt oder ein sehr langes Stück Flechtschlauch immer wieder nach dem selben Prinzip übereinander gestülpt werden. Ein Vorteil dieser Mehrfachumstülpung ist die Möglichkeit einer endlosen Faserablage über mehrere Faserschichten hinweg.Around producing a multilayer preform can either be several short ones Connectors be pushed into each other and then according to the principle described above inverted or a very long piece Braided hose repeatedly on the same principle on top of each other inverted become. An advantage of this multiple overturning is the possibility of a endless fiber tray over several fiber layers away.
Durch den Wegfall der Fügeprozessschritte und -elemente können mit dieser Erfindung Faserverbundfelgen in bisher noch nicht erreichter wirtschaftlicher Effizienz hergestellt werden. Es besteht weiterhin die Möglichkeit zur Integration von Funktionselementen wie Felgennabe, Felgenhörnern und Felgenbefestigungselementen.By the omission of joining process steps and elements can with this invention fiber composite rims in hitherto not yet reached economic efficiency are produced. It still exists the possibility for integration of functional elements such as rim hub, rim flanges and rim fastening elements.
Durch gezieltes Ausnutzen der Zusammenhänge zwischen Flechtwinkel und Flechtschlauchdurchmesser, kombiniert mit der Möglichkeit der Einbringung zusätzlicher axialer Fäden, wird eine optimale kraftflussgerechte Anordnung der Fasern ermöglicht. Mit Flechtschläuchen kann zudem ein steiler Verlauf der Fasern im Scheibenbereich realisiert werden.By targeted exploitation of the relationships between braiding angles and Braided hose diameter, combined with the possibility of introducing additional axial threads, an optimal power flow fair arrangement of the fibers is made possible. With braided hoses In addition, a steep course of the fibers in the disk area can be realized.
Durch Umkehr der Flechtrichtung und Rücklauf der Fasern (umstülpen des Flechtschlauches) werden Faserschlaufen erzeugt. Diese können unter anderem Krafteinleitungszonen bilden oder als Randsaum (Felgenhörner, Felgennabe) genutzt werden. Der sich lokal ändernde Faserwinkel im Schlaufenbereich kann variiert werden, indem die Schlaufe gestreckt oder gestaucht wird.By Reversal of the braiding direction and return fibers (evert Flechtschlauches) fiber loops are generated. These can be among others Forming force zones or as a rim (rim flanges, rim hub) be used. The locally changing one Fiber angle in the loop area can be varied by the Loop is stretched or compressed.
Eine Integration von Nebenformelementen in die geflochtene Faserstruktur ist möglich. Insbesondere ist das Einbringen von weiteren lokalen Faserpreformen sowie anderer Einlegeteile in die Flechtstruktur realisierbar. Einlegeteile können als Krafteinleitungselemente (z.B. Gewindeeinsätze) oder als Formelemente (z.B. Zentrierringe) ausgebildet sein.A Integration of secondary features in the braided fiber structure is possible. In particular, the introduction of other local Faserpreformen as well as other inserts in the braid structure feasible. inserts can as force introduction elements (for example threaded inserts) or as shaped elements (e.g., centering rings).
Über gängige Verfahren wird das entstandene textile Faserhalbzeug mitsamt allfälligen Einlegeteilen zu einer Felge konsolidiert. Für die Konsolidierung zum Verbundwerkstoff können unterschiedliche Matrixsysteme wie etwa Kunststoffe, Keramiken und Metalle gewählt werden. Die vorfixierte Preform des Ausführungsbeispiel wird mittels eines RTM-Harzes und einem mehrteiligen RTM-Werzeugs konsolidiert.About common procedures is the resulting textile semi-finished fiber products together with any inserts consolidated to a rim. For the consolidation to composite material can be different matrix systems such as plastics, ceramics and metals are chosen. The prefixed Preform of the embodiment is using an RTM resin and a multi-part RTM tool consolidated.
Durch die Verwendung von geflochtenen gestülpten Endlosfasern können im Sinne der Aufgabenstellung Felgenstrukturen in kurzen Zykluszeiten ökonomisch gefertigt und die angestrebte Masseeinsparung erreicht werden. Insbesondere können dabei die an die Felgenstruktur gestellten Anforderungen durch die anpassbare Faserorientierung erfüllt werden.By the use of braided inverted continuous fibers can be used in the Purpose of the task Rim structures in short cycle times economically manufactured and the desired mass savings can be achieved. Especially can while the requirements imposed on the rim structure by the customizable fiber orientation can be met.
