BESCHREIBUNGDESCRIPTION

Vorderradaufhängung fur KrafträderFront suspension for motorcycles

Gegenwärtig wird das Vorderrad von Krafträdern fast ausnahmslos mittels einerTeleskopgabel geführt, entweder in der herkömmlichen Weise, indem die amLenkkopf befestigten Standrohre in die am Vorderrad befestigten Gabelhülsen eintauchen, oder in umgekehrter Weise bei der Upside - down - Gabel. DieTeleskopgabel steht dabei in einem Winkel von ca. 60° zur Fahrbahnebene, um die Schwingungen des auf der unebenen Fahrbahn rollenden Vorderrades in vertikalerRichtung wirksam aufzunehmen und zu dämpfen.Currently, the front wheel of motorcycles is almost always guided by a telescopic fork, either in the traditional way, where the stanchions attached to the steering head dip into the fork sleeves attached to the front wheel, or in the opposite way with the upside-down fork. The telescopic fork is at an angle of approx. 60° to the road surface in order to effectively absorb and dampen the vibrations of the front wheel rolling on the uneven road in a vertical direction.

Hervorgerufen durch den langen Hebelarm und die horizontale Steifheit derGabelholme der Teleskopgabel ergeben sich jedoch zum Teil starke Biegemomente im Lenkkopf, vor allem bei der Überwindung von größeren Unebenheiten bzw.Hindernissen.However, the long lever arm and the horizontal stiffness of the fork legs of the telescopic fork can sometimes result in strong bending moments in the steering head, especially when overcoming larger bumps or obstacles.

Das Problem besteht im "Einnicken" des Fahrzeugs mit der Gefahr des Verdrehensdes Lenkers oder sogar des Aushebens des Kraftrades infolge der Hebelwirkung derTeleskopgabel auf den Lenkkopf und damit auch auf den gesamten Rahmen.The problem is that the vehicle "nodding" with the risk of twisting the handlebars or even lifting the motorcycle due to the leverage of the telescopic fork on the steering head and thus on the entire frame.

Durch die Führung des Vorderrades mittels einer Langarm - Vorderradschwingekönnen selbst noch große Fahrbahnunebenheiten oder Hindernisse überwunden werden, da hierdieSchwinge auch bei vollkommen horizontal wirkenden Kräftennoch einfedert (Fig. 2). Die auf das Vorderrad wirkende Kraft wird über die Schwinge und die Verbindungsstange nahezu vollständig auf den im Langarm Führungselementbefestigten Stoßdämpfer übertragen.By guiding the front wheel using a long-arm front wheel swing arm, even large road bumps or obstacles can be overcome, asthe swing arm still compresses even when forces are acting completely horizontally (Fig. 2). The force acting on the front wheel is transferred almost completely to the shock absorber attached to the long-arm guide element via the swing arm and the connecting rod.

Durch eine Massenverschiebung der Langarm - Vorderradschwinge nach vorngegenüber der Teleskopgabel wird außerdem die Haftungsfähigkeit des Vorderrades und die Richtungsstabilität des Fahrzeuges erhöht, was sich besonders positiv beistarken Beschleunigungsvorgängen auswirkt. Die Geradeauslaufstabilität ist durchden positiven Nachlauf des Vorderrades gesichert. Die drehbar gelagerten, seitlicham oberen Teil des Langarm - Führungselementes angebrachten Gabelholme sollen nur führend, nicht dämpfend wirken und verleihen der Gesamtkonstruktion einehöhere Formstabilität, wodurch die genaue Spurhaltung gewährleistet ist.By shifting the mass of the long-arm front swing arm forwardsin relation to the telescopic fork, the grip of the front wheel and the directional stability of the vehicle are also increased, which has a particularly positive effect during strong acceleration. The straight-line stability is ensured by the positive caster of the front wheel. The pivoting fork legs, which are attached to the side of the upper part of the long-arm guide element, are only intended to guide, not dampen, and give the overall construction a higher dimensional stability, which ensures precise tracking.
