Description

Zweiachsiges Fahrzeug, vorzugsweise Fahrrad Die Erfindung betrifft ein zweiachsiges Fahrzeug, vorzugsweise Fahrrad.Two-axle vehicle, preferably bicycle The invention relates to a two-axle vehicle, preferably a bicycle.

Zweiräder sind in der heutigen Form schon seit langem üblich. Nachteilig ist bei ihnen, daß sie außer den Luftreifen nur eine kurzhubige Zusatzfederung besitzen, die sich nur auf das Vorderrad beschränkt. Diese Federung ist aber nicht in der Lage, die hauptsächlichen Stöße aufzunehmen.Two-wheelers have long been common in their current form. Disadvantageous is with them that apart from the pneumatic tires they only have a short-stroke auxiliary suspension, which is limited to the front wheel only. This suspension is not in the Able to absorb the main shocks.

Erfindungsgemäß sind bei einem zweiachsigen Fahrzeug, vorzugsweise Fahrrad, sowohl die vordere als auch die hintere Laufradachse in schwingenden, etwa senkrecht zur Hauptrichtung der beim Fahren aufzunehmenden Stöße gefederten Hebeln gelagert. Das schwingende Nachgeben der beiden Radachsen ist dabei durch elastische Kräfte, z. B. durch Gummibänder, Blattfedern oder Torsionsfedern, gedämpft. Damit durch die Schwingbewegungen der Hinterradachse die Kraftübertragung auf diese Achse möglich bleibt, ist die hintere Achse so angeordnet, daß sie um die Achse eines Antriebsrades, z. B. eines Kettenantriebsrades, schwingt.According to the invention, in a two-axle vehicle, preferably Bicycle, both the front and the rear wheel axle in swinging, approximately spring-loaded levers perpendicular to the main direction of the impacts to be absorbed when driving stored. The oscillating yielding of the two wheel axles is due to elastic Forces, e.g. B. dampened by rubber bands, leaf springs or torsion springs. In order to due to the oscillating movements of the rear wheel axle, the power is transmitted to this axle remains possible, the rear axle is arranged so that it is around the axis of a Drive wheel, e.g. B. a chain drive wheel, swings.

Um eine niedrige Schwerpunktlage zu erhalten, werden Laufräder verwendet, die etwa halb so groß sind wie die eines normalen Fahrrades. Durch eine Zwischenübersetzung vom Tretkurbelzahnrad zum hinteren Laufrad wird unter Verwendung eines auf der Schwingachse des Hinterrades gelagerten Kettenrades die als zweckmäßig erprobte Gesamtübersetzung von der Tretkurbel bis zum Hinterrad erzielt.Impellers are used to maintain a low center of gravity which are about half the size of a normal bicycle. Through an intermediate translation from the crank gear to the rear wheel is made using one on the swing axle of the rear wheel mounted sprocket, the overall transmission that has been tried and tested as appropriate from the crank to the rear wheel.

Mit Rücksicht auf die gute Federung durch die schwingenden Laufradachsen ist es möglich, die Reifen als Hochdruckreifen auszuführen. Die zur Federung der Schwingachsen verwendeten Gummibänder oder Zugfedern können für eine beliebige Spannungsvoreinstellung hergerichtet sein, z. B. können die Gummibänder mit Ösen versehen sein, mittels deren man sie bei gewünschter V orspannung einhängen kann.With regard to the good suspension due to the swinging wheel axles it is possible to run the tires as high-pressure tires. The suspension of the Oscillating axles used rubber bands or tension springs can be used for any tension presetting be prepared, e.g. B. the rubber bands can be provided with eyelets, by means of which they can be hung in at the required voltage.

Zur Erläuterung der Erfindung dient ein Ausführungsbeispiel, dessen Einzelheiten aber nicht eine Festlegung der Erfindung in dem Sinne bedeuten sollen, daß nicht bei gleichen Wirkungen auch andere konstruktive Lösungen anwendbar sind.An exemplary embodiment is used to explain the invention Details are not intended to mean a definition of the invention in the sense that that other constructive solutions cannot be used with the same effects.

In der Zeichnung ist ein Fahrrad mit Tretkurbel wiedergegeben, bei dem sowohl die Laufachse des Vorderrades in einer Gabe14, 5 als auch des Hinterrades in einer Schwinggabel befestigt sind, die etwa 45° nach rückwärts gegen die Horizontale geneigt stehen. Durch diese Schrägstellung erreicht man eine sehr wirksame Abfederung gegen die von Unebenheiten der Straße herrührenden Stöße. Die Schwingungen dieser Hebel werden beim Vorderrad durch eine Feder 6 und beim Hinterrad durch den Hebelarm 1 und eine Feder 3 gedämpft. Mit Rücksicht auf den Kettenantrieb 10 ist die Schwingachse 2 des Hinterrades zugleich die Achse eines Kettenrades 12, das seinerseits mit dem Kettenrad der Tretkurbel 9 verbunden ist. Der Sattelträger 7 ist noch zusätzlich für sich abgefedert durch eine Feder B.In the drawing, a bicycle with a crank is shown, at both the running axis of the front wheel in a Gabe14, 5 and the rear wheel are attached in a tuning fork, which is about 45 ° backwards against the horizontal stand inclined. A very effective cushioning is achieved through this inclination against the bumps caused by bumps in the road. The vibrations of this Lever on the front wheel by a spring 6 and on the rear wheel by the lever arm 1 and a spring 3 damped. With regard to the chain drive 10 is the swing axis 2 of the rear wheel at the same time the axis of a sprocket 12, which in turn with the Chain wheel of the crank 9 is connected. The saddle carrier 7 is also additional cushioned by a spring B.

Die beiden Laufräder sind mit Hochdruckreifen 11 versehen, man kann sogar für diesen Zweck einen Voll- oder Hohlgummireifen verwenden, da die Federung des Rades im ganzen durch die Schwingachsen, die normalerweise um etwa 45° geneigt stehen, eine bessere Federung ergibt als Niederdruckreifen.The two wheels are fitted with high-pressure tires 11, you can even use a solid or hollow rubber tire for this purpose, as the suspension of the wheel as a whole by the oscillating axes, which are normally inclined by about 45 ° stand, gives better suspension than low-pressure tires.
