Description

Die Erfindung betrifft eine Fahrrad-Federung, die durch Einwirkung eines zweiarmigen Hebels, auf einen als Blattfeder ausgebildeten einarmigen Hebel eine ruhige und gleichmäßige Federung bewerkstelligt, wobei die Verbindung zwischen dem zweiarinigen und dem einarmigen Hebel verstellbar ist. Hierdurch ist die Möglichkeit gegeben, durch Verlängern oder Verkürzen des ei,närmigen Hebels (Blattfeder) die Federung der jeweiligen Radbelastung anzupassen.The invention relates to a bicycle suspension, which by action a two-armed lever on a one-armed lever designed as a leaf spring a smooth and even suspension is achieved, with the connection between the two-armed lever and the one-armed lever is adjustable. This creates the possibility given by lengthening or shortening the egg-shaped lever (leaf spring) the Adapt the suspension to the respective wheel load.

Bei den bis jetzt ini Handel befindlichen Fahrrädern wurde das Hauptaugenmerk auf einen gut hgefederten Sattel gelegt, während alle Stöße, die # durch Fahren auf unebenen Straßen usw. sich auf den nicht federnden Rahmen bzw: Gabel auswirken und hier vorzeitige Zerstörungen verursachen, vollkommen unberücksichtigt blieben.The main focus has been on the bicycles that have been in trade up to now placed on a well-sprung saddle, during all the shocks that # by driving on uneven roads etc. affect the non-springy frame or fork and cause premature destruction here, were completely disregarded.

Die Vorteile der neuen Federung bestehen nicht nur in einem angenehmeren Fahren, sondern auch in der Schonung des ganzen Rades.The advantages of the new suspension are not just more comfortable Driving, but also protecting the whole bike.

Iti der Zeichnung ist die Fahrrad-Federung in einem Ausführungsbeispiel dargestellt.Iti the drawing is the bicycle suspension in one embodiment shown.

1?ig. I zeigt die Seitenansicht, Fig. 1I die Vorderansicht, während Fig.1II die Blattfeder in der Draufsicht zeigt. Fig. I und III zeigen eine Blattfeder i, die durch einen Bügel 2 mit der Radgabel 6b starr verbunden, ist. Ein U-förmiger Bügel 4 ist' bei 4a mit der Blattfeder i und bei 5b mit einem zweiarmigen Hebel 5 verbunden und durch einen Sicherungsbügel 3 an der Blattfeder gesichert. Ein Anschlag 6 zur Begrenzung des Hebels 5 ist bei 6a mit der Radgabel 6b und dem zAveiarmigen Hebels verbunden. Eiine Schutzkappe 7 ist bei 6a und 7a befestigt und schützt den Anschlag 6 zur Begrenzung des Anschlages dies Hebels 5 gleichzeitig gegen Verdrehung. Ein U-förmiger Bügel 4 greift bei 4a vermittels eines Nockens in die Blattfeder i ein. Er ist auf der Blattfeder mittels Rasten verstellbar und kann somit der jeweiligen Radbelastung angepaßt werden. Bei Belastung drückt die Radgabel 6b bei 6a den zweiarmigen Hebel 5, an dem bei 5a die Radachse gelagert ist, nach unten, wodurch der U-förmige Bügel 4, der bei 5b drehbar gelagert ist, nach oben gegen die Blattfeder i gedrückt wird. Dadurch tritt dieselbe als Druckausgleich in Tätigkeit. Bei einer Überbelastung des Rades tritt der Anschlag 6 .zur Begrenzung des Anschlages des .Elebels 5 in Tätigkeit. In diesem Fall nimmt die Blattfeder i nur die i'hr zugedachte Belastung auf, während jede weitere Belastung durch den Begrenzer 6 auf die Radgabel übertragen wird'. Die Blattfeder i (Fig. III) ist an mehreren Stellen ja his ic durchbohrt. Die Löcher dienen zum Verstellen des U-förmigen Bügels 4 je nach Belastung.1? Ig. I shows the side view, Fig. 1I the front view, while Fig.1II shows the leaf spring in plan view. Fig. I and III show a leaf spring i, which is rigidly connected to the wheel fork 6b by a bracket 2. A U-shaped one Bracket 4 is' at 4a with the leaf spring i and at 5b with a two-armed lever 5 connected and secured by a safety bracket 3 on the leaf spring. An attack 6 to limit the lever 5 is at 6a with the wheel fork 6b and the zAveiarmigen Lever connected. A protective cap 7 is attached at 6a and 7a and protects the Stop 6 to limit the stop this lever 5 at the same time against rotation. A U-shaped bracket 4 engages in the leaf spring at 4a by means of a cam i a. It can be adjusted on the leaf spring by means of notches and can therefore be used with the respective Wheel load can be adjusted. When loaded, the wheel fork 6b pushes the two-armed fork at 6a Lever 5, on which the wheel axle is mounted at 5a, downwards, whereby the U-shaped Bracket 4, which is rotatably mounted at 5b, pressed upwards against the leaf spring i will. As a result, it acts as a pressure equalization. In the event of an overload of the wheel, the stop 6 occurs to limit the stop of the .Elebels 5 in Task. In this case, the leaf spring i only takes the load intended for it on, while any further load is transferred to the wheel fork by the limiter 6 will'. The leaf spring i (Fig. III) is pierced in several places. The holes are used to adjust the U-shaped bracket 4 depending on the load.

Die im vorstehenden beschriebene Fährrad-Federung kann auch auf das Hinterrad oder auf Vorder-und Hinterrad übertragen werden.The bicycle suspension described above can also be applied to the Rear wheel or to be transferred to the front and rear wheel.
