BeschreibungDescription
Teleskopgabel für Fahr- und Motorräder, die eine sich über den Federweg veränderbare Verschiebung der Tauch- und Gleitverbindungsteile zuläßt.Telescopic fork for bicycles and motorcycles, which allows a variable displacement of the plunger and sliding connection parts over the suspension travel.
Bei der Konstruktion der vorliegenden Telegabel handelt es sich um eine, speziell bei Motorrädern und Fahrrädern verwendete, in sich verschiebbare Verbindung, die ein Ein- und Ausfedern des Vorderrades sowohl beim überfahren von Bodenwellen als auch beim Anbremsen oder Beschleunigen zuläßt. Duch die spezielle, dreiteilige, Ausführung kann dabei, je nach Abstimmung der einzelnen Ferderungsraten und Dämpfungsraten der Verbindungsteile zueinander eine unterschiedliche Relativbewegung der einzelnen Verbindungsteile über den gesamten Federweg erreicht werden, über den Verlauf des Federweges beim Einfedern und Anbremsen kann so eine zusätzliche Veränderung des Lenkwinkels, z. B. in Verbindung mit einem variabel aufgehängten Lenkpunkt, erreicht werden, die sich von der bisher bekannten, durch das Einfedern einer herkömmlichen Telegabel allein hervorgerufenen, unterscheidet.The design of this telescopic fork is a sliding connection, used specifically on motorcycles and bicycles, which allows the front wheel to compress and extend when driving over bumps and when braking or accelerating. The special three-part design means that, depending on how the individual suspension rates and damping rates of the connecting parts are coordinated with one another, a different relative movement of the individual connecting parts can be achieved over the entire spring travel. An additional change in the steering angle can be achieved over the course of the spring travel when compressing and braking, for example in conjunction with a variably suspended steering point, which differs from the previously known change caused by the compression of a conventional telescopic fork alone.
Bei den bisher bekannten zweiteiligen Teleskopgabeln bei Fahrrädern und Motorrädern ergibt sich nur eine einzige Bewegung der zwei Verbindungselemente im Verlauf des Ein- und Ausfederns beim Überfahren von Bodenwellen oder beim Bremsen und Beschleunigen. Dadurch werden bei beiden Fahrsituationen die gleichen geometrischen Veränderungen von Lenkwinkel und Nachlauf des Vorderrades erzielt.With the two-part telescopic forks on bicycles and motorcycles that are known to date, there is only a single movement of the two connecting elements during compression and rebound when driving over bumps or when braking and accelerating. This means that the same geometric changes in the steering angle and caster of the front wheel are achieved in both driving situations.
Die gleiche Veränderung der Fahrwerksgeometrie bei den unterschiedlichen Fahrsituationen verhindert eine Optimierung des Fahrverhaltens dieser Fahrzeuge in diesen Fahrsituationen.The same change in chassis geometry in different driving situations prevents optimization of the driving behavior of these vehicles in these driving situations.
Die nunmehr vorliegende Konstruktion einer Telegabel unterteilt, durch die dreiteilige Ausführung und die damit mögliche, unterschiedliche Abstimmung der einzelnen Verbindungselemente, die Federwege beim Überfahren von Bodenwellen und beim Anbremsen/Beschleunigen in zwei unterschiedliche Relativbewegungen der Verbindungselemente zueinander auf. In Verbindung mit geometrisch entsprechend ausgelegten Umlenkhebeln zur Veränderung der Lenkachse, die z.B. mit dem mittleren Verbindungselement der Telegabel verbunden sind, kann so das Fahrverhalten dieser Fahrzeuge optimiert werden. Gleichzeitig ist die Biegesteifigkeit einer solchen, erflndungsgemäßen, Telegabel höher, da eine größere Überlappung der einzelnen Verbindungselemente zueinander gegeben ist.The current design of a telescopic fork, thanks to the three-part design and the resulting different coordination of the individual connecting elements, divides the spring travel when driving over bumps and when braking/accelerating into two different relative movements of the connecting elements to one another. In conjunction with geometrically designed deflection levers for changing the steering axis, which are connected, for example, to the middle connecting element of the telescopic fork, the handling of these vehicles can be optimized. At the same time, the bending stiffness of such a telescopic fork according to the invention is higher because there is a greater overlap of the individual connecting elements with one another.
In einer allgemeinen Ausführung gemäß dem Anspruch 1 wird das untere Verbindungselement 1 der Telegabel (Zeichnung 1), das mit dem zu führenden Vorderrad 6 über eine Achse verbunden ist, innerhalb oder außerhalb des mittleren Verbindungselementes 2 sowie dieses wiederum innerhalb oder außerhalb des obern Verbindungselementes 3 ineinander verschoben.In a general embodiment according to claim 1, the lower connecting element 1 of the telescopic fork (drawing 1), which is connected to the front wheel 6 to be guided via an axle, is displaced inside or outside the middle connecting element 2 and this in turn is displaced inside or outside the upper connecting element 3.

Die vorgeschlagene Konstruktion einer Telegabel ermöglicht die unterschiedliche Abstimmung der Fahrsituationen des Überfahrens einer Bodenwelle oder des Anbremsens. Durch die dreiteilige Ausführung wird, je nach Abstimmung, eine unterschiedliche Relativbewegung der einzelnen Verbindungselemente zueinander erreicht.The proposed design of a telescopic fork enables different adjustments to the driving situations of driving over a bump or braking. The three-part design allows a different relative movement of the individual connecting elements to one another, depending on the adjustment.
Diese kann in Verbindung mit Umlenkhebeln, je nach Abstimmung der erfindungsgemäßen Konstruktion, innerhalb einer Vorderradaufhängung für Fahr- oder Motorräder, einen Effekt erzielen, der die Lenkung beim Anbrenmsen stabilisiert aber glichzeitig die Richtungsänderung und das Überfahren von Bodenwellen vereinfacht.In conjunction with rocker arms, depending on the design according to the invention, within a front wheel suspension for bicycles or motorcycles, this can achieve an effect that stabilizes the steering when braking but at the same time simplifies the change of direction and driving over bumps.
