Abstract

A controlled front wheel, which is driven by the use of muscular power, in the case of single-track vehicles and tricycles, with a low seat position for the driver - approximately 40 to 50 cm above the ground and between the two axles - and where the entire propulsion mechanism is mounted on the movable front-wheel fork which forms a smaller, i.e. more oblique angle with the ground than is formed in the case of conventional two-wheelers. The combination of the propulsion mechanism which is attached to the front-wheel fork, is operated by muscular power and is concomitantly moved when steering, and with a low seat position (see above) with a more pronounced inclination of the fork with respect to the ground than is customary in the case of two-wheelers, is the new idea which has the effect that a vehicle of this type can be driven without effort and safely since the pedalling forces which influence the steering can readily be sustained at the handlebars by the driver, as described above (Figure 1). <IMAGE>

Description

Die Erfindung betrifft das technische Gebiet der muskelgetriebenen Fahrzeuge (Fahrräder, Dreiräder).The invention relates to the technical field of muscle-driven Vehicles (bicycles, tricycles).

Es soll ein Fahrzeug entstehen, einspurig (als Fahrrad) oder als Dreirad, jeweils mit gesteuertem Vorderrad, das durch die geringe Sitzhöhe des Fahrers - etwa 40 bis 50 cm über dem Erdboden - eine größere Sicherheit für den Fahrer ergibt, ein Absteigen an Ampeln unnötig macht und eine bessere Aerodynamik bewirkt. Der Fahrer sitzt zwischen Vorder- und Hinterrad (-rädern) im bestgefederten Raum. Ein Vorderradantrieb wurde gewählt, weil zum einen das Fahrzeug kürzer als die neu aufgekommenen Liegeräder gebaut werden kann, zum anderen - und das ist sehr wichtig bei dieser sesselartigen Sitz­ stellung des Fahrers - kann eine weiche Sitz- oder Hinterradfederung eingebaut werden, die sich bei angetriebenem Hinterrad wegen des durch die Tretarbeit entstehenden Aufschaukeleffekts bisher bei Fahrrädern nicht hat durchsetzen können, die aber bei dieser sesselartigen Liege­ sitzstellung erforderlich ist.A vehicle should be created, single track (as a bicycle) or as Tricycle, each with a controlled front wheel, due to the low Seat height of the driver - about 40 to 50 cm above the ground - one greater safety for the driver results in dismounting at traffic lights makes unnecessary and better aerodynamics. The driver is sitting between the front and rear wheel (wheels) in the best suspension room. A front wheel drive was chosen because, firstly, the vehicle shorter than the newly emerging recumbent bikes can be built to others - and that's very important with this armchair-like seat position of the driver - can have a soft seat or rear suspension be installed, which are driven by the rear wheel because of the rocking effect of bicycles could not prevail, but with this armchair-like couch sitting position is required.

Der durch Muskelkraft betätigte Antriebsmechanismus (durch Ketten­ räder, Kette und Kurbel, Hebel oder durch Riemen oder Zahnräder) (Fig. 1 und 2) ist an der lenkbaren Gabel des Vorderrades befestigt, um ein Abspringen der Kette zu verhindern. Durch diese Anordnung wird aber die Lenkung durch die Tretarbeit zu stark beeinflußt. Um diese Beeinflussung so gering zu halten, daß sie am Lenker leicht aus­ geglichen werden kann - und dies ist der Kern dieser Idee -, erhält die Gabel eine starke Neigung zum Erdboden - etwa 35 bis 55 Grad -, denn bei einer Neigung von z. B. 45 Grad werden die die Lenkung beein­ flussenden Tretkräfte zu 50% durch die Gabellagerung aufgenommen, und der Rest kann am Lenker leicht ausgeglichen werden, wie es die Fahrversuche bewiesen.The drive mechanism operated by muscle power (by chain wheels, chain and crank, lever or by belt or gear wheels) ( Fig. 1 and 2) is attached to the steerable fork of the front wheel to prevent the chain from jumping off. With this arrangement, however, the steering is influenced too much by the pedal work. In order to keep this influence so low that it can be easily balanced on the handlebars - and this is the essence of this idea - the fork gets a strong inclination to the ground - about 35 to 55 degrees - because with an inclination of e.g. B. 45 degrees, the steering influence influencing pedal forces are absorbed 50% by the fork bearing, and the rest can be easily balanced on the handlebar, as the driving tests proved.

Ein Hebelantrieb hat dabei zwei zusätzliche Vorteile: Erstens wird die Beeinflussung der Lenkung durch die Tretarbeit weiter reduziert, und zweitens braucht der Fahrer die Füße nicht über die Antriebsachse zu heben (Fig. 2).A lever drive has two additional advantages: firstly, the influence on the steering by pedaling is further reduced, and secondly, the driver does not need to lift his feet above the drive axle ( Fig. 2).
