Description

Die Abfederung von Motor-, Fahrrad- und anderen Sätteln erfolgt mittels Federn, die durchweg aus bloßem Federstahl bestehen. Der Nachteil derartiger Federungen besteht darin, daß sie entweder weich ansprechen und dann zum Durchschlagen neigen oder aber nicht durchschlagen, dafür aber zu Beginn der Federarbeit zu hart ansprechen. Diese Nachteile etwa dadurch zu beseitigen, daß mehrere Federn verschiedener Federkonstante hintereinandergeschaltet werden, hat zu keinem brauchbaren Ergebnis geführt.The cushioning of motor, bicycle and other saddles is carried out by means of Springs that consist entirely of bare spring steel. The disadvantage of such suspensions is that they either respond softly and then tend to bottom out or not through, but respond too hard at the beginning of the spring work. To eliminate these disadvantages, for example, that several springs of different spring constants connected in series did not lead to any useful result.

Die Erfindung besteht darin, .daß eine Schraubenfeder aus Federstahl um einen geeignet vulkanisierten, in seiner Härte abgestimmten Gummikern derart herumgewickelt ist, daß zu Beginn der Federarbeit der Gummikern zwischen die Federwindungen auszuweichen vermag. Je mehr die Federwindungen einander genähert werden, um so weniger wird diese Ausweichmöglichkeit und um so härter wird der Gummikern. Zu Beginn der Federarbeit spricht also die Federung gemäß der Erfindung weich an, um mit zunehmender Federarbeit härter zu werden.The invention consists in .that a coil spring made of spring steel around a suitably vulcanized rubber core with a matched hardness is wound around that at the beginning of the spring work the rubber core between the spring coils able to evade. The closer the coils of the spring are brought to one another, the more so This alternative option becomes less and the rubber core becomes harder. At the start the spring work so the suspension according to the invention responds softly to with increasing Spring work to get harder.

In der Zeichnung ist die Federung in beispielsweiser Ausführung an einem Motorradsattel im Schnitt dargestellt. Der in an sich bekannter Weise um die Achse i drehbare Sattel 2 ist über eine Druckschraubenfeder 3 gegen das Gestell 4 abgefedert. Die Feder ist erfindungsgemäß um einen Gummikern gewickelt, der bei dem gezeichneten Ausführungsbeispiel als Schlauch 5 ausgebildet ist und im Innern einen Führungsbolzen 6 aufweist. Bei Belastung des Sattels 3 wird nicht nur die Feder 3, sondern auch die Gummihülse 5 zusammengedrückt, die dabei zwischen die Federwindungen auszuweichen versucht und dadurch die zu Beginn weich ansprechende Federung mit zunehmender Federarbeit härter werden läßt, bis schließlich die Federwindungen mit dem dazwischenliegenden Gummi nicht weiter zusammengedrückt werden können.In the drawing, the suspension is on in an exemplary embodiment a motorcycle saddle shown in section. The in a known manner around the Axis i rotatable saddle 2 is against the frame via a compression coil spring 3 4 cushioned. According to the invention, the spring is wound around a rubber core, which at the illustrated embodiment is designed as a hose 5 and inside has a guide pin 6. When the saddle 3 is loaded, not only the Spring 3, but also the rubber sleeve 5 compressed, which is between the Tries to avoid spring coils and thereby the softly appealing at the beginning Suspension becomes harder with increasing spring work, until finally the spring coils with the rubber in between cannot be squeezed any further.

Wenn erforderlich, kann bei schlauchartigem Gummikern auch in dessen Innerm eine Feder vorgesehen sein, so daß der Gummikern zwischen den Windungen der äußeren und denjenigen der Innenfeder zu liegen kommt.If necessary, a hose-like rubber core can also be used in its Inside a spring be provided so that the rubber core between the turns of the outer and those of the inner spring come to rest.

Die Härte des Gummikerns muß mit der Federkonstante abgestimmt sein, um die beschriebene progressiv wirkende Federarbeit zu gewährleisten.The hardness of the rubber core must be matched to the spring constant, to ensure the progressively acting spring work described.
