Abstract

The booster system for a bicycle uses deflections of the rear suspension over bumps and potholes to assist forward motion. The energy generated when the suspended rear wheel is deflected, is stored before being converted into forward motion energy. The pulsating deflection energy is stored in eg. a torsion spring (4), elastomer part, compressed air chamber, or compressed oil chamber, and is continuously supplied to the bottom bracket bearing shaft. Several energy accumulated elements may be used together.

Description

System zur Unterstützung des Antriebs eines hinterradgefederten Fahrrads, welches die Federenergie des Hinterrades in Fortbewegungsenergie umwandelt.System to support the drive of a rear suspension bike, which converts the spring energy of the rear wheel into locomotion energy.

Die heutzutage verwendeten Federungssysteme arbeiten ausschließlich mit dem Ziel, die Energie, die beim Einfedern des Hinterrades entsteht, zu dämpfen und zu annullieren.The suspension systems used today only work with The goal is to dampen the energy generated by the compression of the rear wheel and cancel.

Diese Energie läßt sich jedoch mit Hilfe einer Torsionsfeder oder einem ähnlichen Speicherelement auf die Tretlagerachse umwandeln und somit als Fortbewegungs­ energie nutzen.However, this energy can be absorbed by means of a torsion spring or the like Convert storage element to the bottom bracket axis and thus as a locomotion use energy.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Anspruch 3 angegeben. Demnach erreicht man durch die versetzte Kombination unterschiedlicher Speicher­ elemente eine verbesserte Speicherung der Energie.An advantageous embodiment of the invention is specified in claim 3. According to this, the offset combination of different storage systems can be used elements an improved storage of energy.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is shown in the drawings and will described in more detail below.

Die Erfindung wird anhand Fig. 3 erläutert. The invention is explained with reference to FIG. 3.

Aufbauend auf dem bereits bekannten Federungssystem, in welchem die Hinter­ radschwinge 2 mit dem Hauptrahmen 1 gemeinsam auf der Tretlagerachse 3 ge­ lagert ist, baut man eine Torsionsfeder (Schneckenfeder) 4 so ein, daß sie sich durch die Aufwärtsbewegung des Hinterrads vorspannt. Mit Hilfe des Frei­ laufs 5a, der zwischen Hinterradschwinge und Torsionsfeder liegt und der bewirkt, daß sich die Feder bei jeder Einfederbewegung weiter vorspannt und beim Aus­ federn gespannt bleibt. Zwischen Torsionsfeder 4 und Tretlagerachse 3 liegt der Freilauf 5b, mit der Aufgabe die Energie der vorgespannten Torsionsfeder auf die Tretlagerachse abzugeben und die Vor- und Zurückbewegung der Tretlager­ achse ohne Einfluß der Torsionsfeder zu gewährleisten.Building on the already known suspension system, in which the rear swing arm 2 with the main frame 1 is jointly supported on the bottom bracket axis 3 , a torsion spring (helical spring) 4 is built in so that it is pretensioned by the upward movement of the rear wheel. With the help of free running 5 a, which lies between the rear swing arm and torsion spring and which causes the spring to be further biased with each compression movement and remains tensioned when the springs are off. Between torsion spring 4 and bottom bracket axis 3 is the freewheel 5 b, with the task of releasing the energy of the prestressed torsion spring on the bottom bracket axis and the back and forth movement of the bottom bracket axis without the influence of the torsion spring.

Die Freiläufe, welche in diesem System verwendet werden, sind baugleich mit den Freiläufen, die bewirken, daß die Kraft der Kette auf das Hinterrad übertra­ gen wird, allerdings keinen Einfluß auf das Vor- und Zurückrollen des Rades hat.The freewheels that are used in this system are identical in construction to the freewheels that cause the power of the chain to transfer to the rear wheel is, however, has no influence on the forward and backward rolling of the wheel.

So kann die Energie, die beim Einfedern des Hinterrades pulsierend entsteht, kurzzeitig gespeichert und kontinuierlich auf die Tretlagerachse abgegeben werden. Als Dämpfungselement verwendet man eine konventionelle Federungseinheit, die allerdings auf die Torsionsfeder abgestimmt sein muß.So the energy that pulsates when the rear wheel is deflected stored for a short time and continuously delivered to the bottom bracket axle. A conventional suspension unit is used as the damping element however, must be matched to the torsion spring.
