Zentrifugal-Radspeiche
BeschreibungCentrifugal wheel spoke
Description

Herkömmliche Radspeichen dienen einzig als starre Verbindung zwischen Radnabe (Zentrum) und Radfelge (Außenkranz) eines Rades.Conventional wheel spokes serve only as a rigid connection between the wheel hub (center) and the wheel rim (outer rim) of a wheel.

Mit herkömmlichen Speichen ist es nicht möglich, durch eine Massen verschiebung einen Schwungradeffekt zu erzielen.With conventional spokes it is not possible to achieve a flywheel effect through a mass shift.

Dieses Problem wird dadurch gelöst, daß man einem Gewicht freie Bewegung innerhalb oder entlang einer Führung, ermöglicht.This problem is solved by allowing a weight to move freely within or along a guide.

Diese Führung kann ein staub- und schmutzgeschütztes System sein, rund oder eckig, z.B. mit Nut und / oder Feder, es kann ein Stab sein, oder mehrere, auf dem / denen das Gewicht mit entsprechender / entsprechenden Bohrung(en) gleiten kann, vergleichbar einem Trainingsgewicht auf einer Hantelstange.This guide can be a dust and dirt-protected system, round or square, e.g. with a tongue and/or groove, it can be one bar, or several, on which the weight can slide with the corresponding hole(s), comparable to a training weight on a barbell.

Zum äußeren Radius hin wird das Gewicht durch eine Feder abgefangen. Diese ist so konstruiert, daß sich ihr Widerstand um so mehr erhöht, je schneller sich das Rad dreht, also je weiter sie komprimiert wird.Towards the outer radius, the weight is absorbed by a spring. This is designed in such a way that its resistance increases the faster the wheel rotates, i.e. the more it is compressed.

Durch die Zentrifugalkraft wird also bei zunehmender Drehzahl das Gewicht vom Zentrum fort bewegt, bei nachlassender Drehzahl durch den Federdruck entgegen der Zentrifugalkraft zum Zentrum zurück. Bezogen auf ein Fahrrad wird dadurch folgender Effekt erzielt:As the speed increases, the centrifugal force causes the weight to move away from the center, and as the speed decreases, the spring pressure pushes it back to the center against the centrifugal force. In relation to a bicycle, this achieves the following effect:

beim Anfahren oder bei sehr langsamer Fahrt treten keine zusätzlichen Schwungmassen auf, ist also keine zusätzliche Muskelkraft erforderlich. Mit zunehmender Geschwindigkeit wandert das Gewicht immer weiter nach außen. Das Rad erhält dadurch zusätzliche Schwungmasse. Dies hat zur Folge, daß sich das Rad schneller dreht, und zum Selbstläufer wird. Bei langsamerer Fahrt läßt dieser Effekt wieder nach, bei abruptem Abbremsen wird das Gewicht schlagartig zur Nabe zurück Befördert.When starting off or driving very slowly, no additional inertia occurs, so no additional muscle power is required. As the speed increases, the weight moves further and further outwards. This gives the wheel additional inertia. This means that the wheel turns faster and becomes self-propelled. When driving more slowly, this effect diminishes, and when braking abruptly, the weight is suddenly returned to the hub.

Claims (2)

1. Zentrifugal-Radspeiche, dadurch gekennzeichnet, daß die Speiche aus einem festen, stabilisierenden Anteil besteht, sowie aus einem beweglichen Gewicht, und einer Feder. 1. Centrifugal wheel spoke, characterized in that the spoke consists of a fixed, stabilizing part, as well as a movable weight and a spring. 2. Zentrifugal-Radspeiche nach Schutzanspruch 1, dadurch gekennzeichnet, daß mit zunehmender Umdrehungszahl des Rades sich das Gewicht entlang dem stabilisierenden Anteil entgegen dem Federdruck vom Zentrum fort bewegt, und bei nachlassender Umdrehungszahl sofort wieder zum Radzentrum zurück. 2. Centrifugal wheel spoke according to claim 1, characterized in that with increasing rotational speed of the wheel the weight moves along the stabilizing portion against the spring pressure away from the center, and with decreasing rotational speed immediately returns to the wheel center.
