Abstract
Die Erfindung betrifft einen radführender Lenker im Fahrwerk eines Fahrzeugs, dessen Grundstruktur (ohne Anbauteile) vollständig aus einem faserverstärkten thermoplastischen Werkstoff besteht, wobei die Grundstruktur vollumfänglich durch Spritzgießen oder Spritzpressen hergestellt ist. Vorzugsweise besitzt der Lenker keine nennenswerte biegeelastische Eigenschaft, jedoch im Spritzguß- oder Spritzpressprozess ausgebildete Anbindungsstellen. Es kann sich um einen Schwertlenker oder Längslenker oder Schräglenker oder Querlenker handeln mit Langfasern und/oder Kurzfasern und/oder Endlosfasern als Verstärkungsfasern in Form Carbonfasern oder Glasfasern oder Aramidfasern.The invention relates to a wheel guiding handlebar in the chassis of a vehicle whose basic structure (without attachments) consists entirely of a fiber-reinforced thermoplastic material, wherein the basic structure is made entirely by injection molding or transfer molding. Preferably, the handlebar has no significant bending elastic property, but formed in the injection molding or transfer molding process attachment sites. It may be a sword handlebar or trailing arm or trailing arm or wishbone with long fibers and / or short fibers and / or continuous fibers as reinforcing fibers in the form of carbon fibers or glass fibers or aramid fibers.
Description
Die Erfindung betrifft einen radführenden Lenker im Fahrwerk eines Fahrzeugs, dessen Grundstruktur (ohne Anbauteile) vollständig aus einem faserverstärkten thermoplastischen Werkstoff besteht. Zum Stand der Technik wird neben der
Üblicherweise sind radführende Lenker in Fahrwerken von Kraftfahrzeugen aus metallischen Werkstoffen durch Tiefziehen hergestellt und es werden nach dem Tiefziehen alle benötigten Anschluss- bzw. Lagerstellen eingepresst. Bekannt ist weiterhin ein aus Prepregs oder dgl. geformter Lenker (vgl.
Dieser bekannte Stand der Technik erfordert entweder teure Tiefziehwerkzeuge oder besitzt ein relativ hohes Gewicht oder erlaubt keine optimale Anbindung der Lagerstellen oder erfordert mehrere Schritte im Herstellprozess. Daher soll vorliegend ein demgegenüber verbesserter radführender Lenker nach dem Oberbegriff des Anspruchs 1 aufgezeigt werden (= Aufgabe). Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass die Grundstruktur vollumfänglich durch Spritzgießen oder Spritzpressen hergestellt ist. Vorzugsweise besitzt ein solcher erfindungsgemäßer Lenker keine nennenswerte biegeelastische Eigenschaft, d. h. er stellt eine möglichst steife Konstruktion dar, die keine Federungsfunktion übernehmen soll und es sind Anbindungsstellen oder dgl. bereits im Spritzgußprozess oder Spritzpressprozess ausgebildet.This known prior art either requires expensive thermoforming tools or has a relatively high weight or does not allow optimal connection of the bearings or requires several steps in the manufacturing process. Therefore, in the present case, an improved wheel-guiding handlebar according to the preamble of
Vorgeschlagen wird vorliegend somit die vollständige Herstellung eines radführenden Lenkers aus faserverstärktem Thermoplast durch Spritzgießen und/oder Spritzpressen (RTM = Resin Transfer Moulding), was durch den Begriff der Grundstruktur ausgedrückt werden soll. Der eigentliche Lenker als solcher, d. h. ohne eingepresste Gummilager oder Anbauteile oder dgl. soll in seiner „Grundstruktur” in praktisch einem einzigen Arbeitsgang vollumfänglich durch Spritzgießen und/oder Spritzpressen hergestellt sein. Mögliche Ausführungsformen sind Schwertlenker, Längslenker, Schräglenker u. a.. Der thermoplastische Kunststoff kann sowohl lang-, kurz- und endlosfaserverstärkt sein, wobei als Verstärkungsfasern Carbonfasern, Glasfasern, Aramidfasern und sonstige zu Einsatz kommen können. Gleichzeitig ist eine Funktionalisierung, d. h. Anbringung von funktionalen Komponenten wie Lagerstellen, Anschraubpunkten, Rippen und dgl. durch Thermoplastspritzguß möglich. Dadurch ist eine einfache Integration zusätzlicher Anbindestellen für zum Beispiel Feder, Dämpfer usw. möglich. Grundsätzlich kann die Spritzgussmasse sowohl ohne also auch mit Faserverstärkung (Kurzfasern aus Carbon, Glas, Aramid, u. a.) vorliegen, wobei eine Verstärkung zu bevorzugen ist.In this case, the complete production of a wheel-guiding link made of fiber-reinforced thermoplastic by injection molding and / or transfer molding (RTM = Resin Transfer Molding) is proposed, which is to be expressed by the term "basic structure". The actual handlebar as such, d. H. without pressed rubber bearings or attachments or the like. Should be made in its "basic structure" in virtually a single operation fully by injection molding and / or transfer molding. Possible embodiments are sword handlebar, trailing arm, semi-trailing arm u. a .. The thermoplastic material may be both long, short and continuous fiber reinforced, which can be used as reinforcing fibers carbon fibers, glass fibers, aramid fibers and others. At the same time, functionalization, i. H. Attachment of functional components such as bearings, Anschraubpunkten, ribs and the like. By thermoplastic injection molding possible. As a result, a simple integration of additional attachment points for example, spring, damper, etc. possible. In principle, the injection-molding compound can be present both without and also with fiber reinforcement (short fibers made of carbon, glass, aramid, and the like), reinforcement being preferred.
Aus einem kurzfaser- oder langfaser- oder endlosfaser-verstärktem Thermoplast (und somit aus nur einem einzigen Material und nicht durch eine Kombination aus mehreren Materialien) ist in einem einstufigen Herstellungsprozess somit ein erfindungsgemäßer radführender Lenker hergestellt, der sich durch geringes Gewicht, erhöhte geometrische Flexibilität, Korrosionsbeständigkeit und die Reduzierung der ungefederten Massen im Fahrwerk auszeichnet.From a kurzfaser- or long-fiber or endless fiber-reinforced thermoplastic (and thus only a single material and not by a combination of several materials) in an one-step manufacturing process thus an inventive wheel-guiding handlebar is made, characterized by low weight, increased geometric flexibility , Corrosion resistance and the reduction of unsprung masses in the chassis distinguishes.
