Description

Die Erfindung betrifft eine Abfederung für das Vorderrad eines Fahrrades.The invention relates to a suspension system for the front wheel of a bicycle.

Sie besteht darin, daß die umgedreht befestigte Vorderradgabel eines Fahrrades mit einem Schwingbügel versehen ist, welcher mit seinem einen Bügelende in der Achsmitte des Vorderrades gelagert ist, während das andere Ende mit einer-am Schutzblech angebrachten Schraubenfeder in Verbindung steht.It consists in the fact that the front fork is attached upside down Bicycle is provided with a swing arm, which with its one end of the bracket is mounted in the center of the axle of the front wheel, while the other end with an -am Coil spring attached to the guard plate.

Durch diese Art der Befestigung der Vorderradgabel über den abgefederten Schwingbügel wird eine Verlängerung der Federausschwingung, erreicht und dadurch ein weiches, stoßfreiesAbfangen der einzelnen Stoßbelastungen des Vorderrades ermöglicht.This type of attachment of the front fork over the sprung Swing arm is an extension of the spring oscillation, achieved and thereby allows a soft, shock-free interception of the individual shock loads on the front wheel.

Die Abbildungen zeigen ein Ausführungsbeispiel der Erfindung. ' .The figures show an embodiment of the invention. '.

Abb. i zeigt eine Ansicht und Abb. 2 eine Einzelheit.Fig. I shows a view and Fig. 2 shows a detail.

i ist die Vorderradgabel, 2 der Befestigungspunkt für den Schwingbügel 3, 4 die Befestigung des Schwingbügels 3 in der Achsmitte des Vorderrades, 5 eine Zugfeder, 6 eine Felgenbremse, 7 der Befestigungspunkt der Zugfeder 5 am Schwingbügel 3, 8 der Befestigungspunkt der Zugfeder 5 am Schutzblech 9, io der Versteifungsbügel für den Schwingbügel 3 und schließlich i i der Befestigungspunkt für die Blattfeder 12.i is the front fork, 2 the attachment point for the swing arm 3, 4 the attachment of the swing arm 3 in the center of the axle of the front wheel, 5 a Tension spring, 6 a rim brake, 7 the attachment point of the tension spring 5 on the swing arm 3, 8 the attachment point of the tension spring 5 on the protective plate 9, io the stiffening bracket for the swing arm 3 and finally i i the attachment point for the leaf spring 12th

Die Wirkungsweise ist folgende: Die umgedrehte Vorderradgabel i - ist mit ihren beiden Enden bei 2 mit einem Schwingbügel 3 drehbar verbunden. Der Schwingbügel 3, welcher mit seinen vorderen beiden Bügelenden bei 4 in der Achsmitte des Vorderfades drehbar gelagert ist; ist am hinteren Ende mit einer Zugfeder 5 und mit einer Felgenbremse 6 versehen. Die Zugfeder 5 ist 'bei 7 am Schwingbügel 3 und bei 8 am Schutzblech 9 befestigt. Zur besseren Halterung zwischen Bügel 3 und Feder 5 ist ein Versteifungsbügel io angebracht. Durch eine bei i i mit dem Schutzblech 9 verbundene Blattfeder 12 werden die auftretenden senkrechten Stöße abgedämpft, und zwar so, daß die Bereifungsoberfläche die Blattfeder tangential berührt.The mode of operation is as follows: The upturned front fork i - is rotatably connected with its two ends at 2 to a swing arm 3. The swing arm 3, which is rotatably mounted with its two front bracket ends at 4 in the center of the axis of the front wheel; is provided with a tension spring 5 and a rim brake 6 at the rear end. The tension spring 5 is attached to the swing arm 3 at 7 and to the protective plate 9 at 8. For better retention between bracket 3 and spring 5, a stiffening bracket io is attached. By a leaf spring 12 connected to the fender 9 at ii, the vertical shocks that occur are dampened in such a way that the tire surface touches the leaf spring tangentially.
