Fahrradsattelgestell aus Carbonfaser-verstärktem Kunststoff mit KlemmschutzBicycle saddle frame made of carbon fiber reinforced plastic with clamp protection
Die Forderung nach Gewichtsreduktion im Fahrradbau führt auch bei Sattelgestellen zur Verwendung von Carbonfaser-verstärktem Kunststoff (CFK). CFK ist aber spröde und daher anfällig für Kerben und Abrieb, was zum Bruch führen kann. Deshalb werden Sattelgestelle aus CFK üblicher Bauart im Klemmbereich der Sattelstütze durch Hülsen, Schalen oder Geflecht aus Aluminium oder Edelstahl vor Beschädigung geschützt. The demand for weight reduction in bicycle construction also leads to the use of carbon fiber reinforced plastic (CFRP) in saddle frames. However, CFRP is brittle and therefore susceptible to notches and abrasion, which can lead to breakage. This is why saddle frames made of CFRP of the usual design are protected from damage in the clamping area of the seat post by sleeves, shells or mesh made of aluminum or stainless steel.
Der im Schutzanspruch 1 angegebenen E-rfindung liegt das Problem zugrunde, ein Sattelgestell aus CFK herzustellen, dessen Gewichtsvorteil gegenüber Metallgestellen nicht durch den üblichen Klemmschutz reduziert wird.The invention specified in claim 1 is based on the problem of producing a saddle frame made of CFRP whose weight advantage over metal frames is not reduced by the usual clamping protection.
Dieses Problem wird durch die Verwendung eines Klemmschutzes aus Aramidfaserverstärktem Kunststoff (AFK) gelöst, denn AFK verfügt über besonders hohe Zähigkeit, Schlagfestigkeit und Abriebfestigkeit. Dabei beträgt die spezifische Masse von AFK nur etwa die Hälfte von Aluminium und nur etwa ein Sechstel von Edelstahl. Zudem kann der Klemmschutz aus AFK aufgrund der hervorragenden Materialeigenschaften dünnwandiger ausfallen, was den Gewichtsvorteil weiter erhöht.This problem is solved by using a clamp protection made of aramid fiber reinforced plastic (AFK), because AFK has particularly high toughness, impact resistance and abrasion resistance. The specific mass of AFK is only about half that of aluminum and only about a sixth of that of stainless steel. In addition, the clamp protection made of AFK can be made thinner-walled due to the excellent material properties, which further increases the weight advantage.
Der AFK-Klemmschutz umschließt das Sattelgestell als Hülse in den Klemmbereichen der Sattelstütze.The AFK clamp protection encloses the saddle frame as a sleeve in the clamping areas of the seat post.
Eine vorteilhafte Ausgestaltung der Erfindung ist in Schutzanspruch 2 angegeben. Hierbei wird der AFK-Klemmschutz jeweils in Form von 2 Schalen aufgebracht, die das Gestell nur oben und unten vor Beschädigung schützen. Schutz besteht also nur da, wo der Kontakt zu der Sattelstütze zustande kommen kann. Der Vorteil ist hier eine weitere Gewichtsreduktion, da an den Seiten des Gestells kein AFK benötigt wird.An advantageous embodiment of the invention is specified in claim 2. The AFK clamp protection is applied in the form of 2 shells, which only protect the frame from damage at the top and bottom. Protection is therefore only provided where contact with the seat post can occur. The advantage here is a further reduction in weight, since no AFK is required on the sides of the frame.
