BeschreibungDescription

Die in den SchutzansprUchen beschriebene einarmige Gabel basiert in den Grundzügen auf die Funktionsweise herkömmlicher zweiarmiger Upside-down-Gabeln. Die einarmige Bauweise wird durch die stabilisierende Wirkung des Bremsbügels ermöglicht,dadurch kann sich die Achsaufnahme nicht verdrehen und die allgemeine Steifigkeit die durch das Weglassen des einen Gabelarms geschwächt ist wird wiederhergestellt.The single-arm fork described in the claims is based in principle on the functionality of conventional two-arm upside-down forks. The single-arm design is made possible by the stabilizing effect of the brake bracket, which means that the axle mount cannot twist and the general rigidity that is weakened by the omission of one fork arm is restored.

Der Bremsbügel ist mit Aufnahme (II) fest verbunden,läuft aber in den Aufnahmen (I) und (2) vertikal frei beweglich. Der Bremsbügel muß verschiebar gelagert sein, da die an ihm befestigten Felgenbremsen den Weg, bei Federungsbewegungen, der Radfelge mitgehen müssen. Das heißt durch die Anordnung des Bügels als verschiebbares Element verändert sich der Weg zwischen Felgenmittelpunkt, Felgenschulter und Bremsbacken nicht. Bei bisherigen zweiarmigen Upside-down Konstruktionen werden aufgrund des oben beschriebenen Problems Scheibenbremsen eingesetzt.The brake bracket is firmly connected to mount (II), but runs freely vertically in mounts (I) and (2). The brake bracket must be mounted so that it can be moved, since the rim brakes attached to it must follow the path of the wheel rim during suspension movements. This means that the arrangement of the bracket as a movable element means that the path between the rim center, rim shoulder and brake shoes does not change. In previous two-arm upside-down designs, disc brakes are used due to the problem described above.

Auch hier könnten durch den Einsatz eines verschiebaren Bremsbügels (Der im Aufbau,dem in den Schutzansprüchen beschriebenen einarmigen Bremsbügel gleicht und sich nur durch seine zweiarmige Ausführung unterscheidet) herkömmliche preisgünstigere Felgenbremsen der diversen Herstellermarken verwendet werden.Here too, by using a movable brake lever (which is similar in structure to the single-arm brake lever described in the claims and differs only in its two-arm design), conventional, cheaper rim brakes from various manufacturers could be used.

SchutzansprUcheProtection claims Federungsvorrichtung für das Vorderrad von einem Fahrrad, dadurch gekennzeichnet,daß eine einarmige Upside-down-Gabel,mit einem beweglichen Bremsaufnahmebügel versehen ist.Suspension device for the front wheel of a bicycle, characterized in that a single-arm upside-down fork is provided with a movable brake support bracket. (Upside-down = gegenüber herkömmlicher Gabelbauweise sind beim Upside-down Prinzip Tauchrohr und Standrohr miteinander vertauscht)(Upside-down = compared to conventional fork construction, the upside-down principle swaps the fork tube and standpipe) Das Standrohr (7) wird in einer Buchse (6) die mit einer Schiebeaufnahme (I),in der der Bremsbügel (3) läuft,versehen ist,geführt.The standpipe (7) is guided in a bushing (6) which is provided with a sliding mount (I) in which the brake bracket (3) runs. Die Buchse (6) wird zusammengefügt mit Teil (7),in das Tauchrohr eingeschraubt.The bushing (6) is joined with part (7) and screwed into the immersion tube. Am Standrohrunterteil ist die Achsaufnahme (9) angebracht. Sie ist mit der Achsaufnahmenbohrung (8) und der unteren festen Aufnahme (II) des Bremsbügels (3) versehen. Der Bremsbügel (3) ist mit Bremsschuhaufnahmen (4), und an seinem oberen Ende mit einem zusätzlichen Führungselement bestückt.The axle mount (9) is attached to the lower part of the standpipe. It is provided with the axle mount hole (8) and the lower fixed mount (II) of the brake bracket (3). The brake bracket (3) is equipped with brake shoe mounts (4) and an additional guide element at its upper end. Dieses Führungselement läuft in der Aufnahme (2),die mit dem Gabelkopf unterhalb des Lenkkopfs verschraubt ist.This guide element runs in the holder (2), which is screwed to the fork head below the steering head.
