Abstract

The drive for the bicycle is provided by two hydraulic cylinders (1) located next to each other. The hydraulic pressure created by leg power drives a hydraulic wheel fitted on the front and rear wheel of the bicycle. The hydraulic cylinders retract and extend alternately. The rectilinear movement of the hydraulic cylinders is converted into rotational movement by the hydraulic wheel. The wheels of the bicycle are driven by two chain wheels.

Description

Bei Fahrrädern üblicher Bauart wird über zwei Kettenräder das Hin­ terrad angetrieben. Die Krafteinleitung erfolgt über die Pedaldrehung. Für Geschwindigkeitsänderungen wird, über die Kettenradschaltung, ein anderes Übersetzungsverhältnis gewählt. Der Antrieb des Vorderrades mittels Kette ist wegen der Lenkbewegung nicht ohne weiteres lösbar.In the case of bicycles of the usual type, the way is via two chain wheels terrad powered. The force is applied by turning the pedal. For changes in speed, use the sprocket shift another gear ratio selected. The drive of the front wheel a chain is not easily detachable due to the steering movement.

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zu­ grunde, ein Allradantrieb mit stufenloser Geschwindigkeitsänderung zu schaffen.The invention specified in the protection claim addresses the problem basic, an all-wheel drive with stepless speed change to accomplish.

Mit der Erfindung wird erreicht, daß das Vorder- und Hinterrad an­ getrieben werden kann und eine Geschwindigkeitsänderung durch Än­ derung der Hubgrößen der Hydraulikzylinder erreicht wird.With the invention it is achieved that the front and rear wheel on can be driven and a change in speed by Än the stroke sizes of the hydraulic cylinders is achieved.

Ein Ausführungsbeispiel der Erfindung wird anhand der Fig. 1 bis 3 erläutert.An embodiment of the invention is explained with reference to FIGS. 1 to 3.

Fig. 1 Gesamtdarstellung Fig. 1 overall view

Fig. 2 Antrieb Fig. 2 drive

Fig. 3 Hydr. Antrieb Fig. 3 hydraulic drive

Fig. 1 Über das Fußpedal (5) wird der Kolben des Hydraulikzylinders (1) eingedrückt, daß Drucköl fließt über die Hydraulikleitungen (4) zum Hydraulikrad (7) und treibt dieses an. Das abfließende Öl (9) wird dem anderen Hydraulikzylinder zugeleitet und hebt dessen Kolben an. Die Kolbenstange mit Fußpedal fährt aus. Die Hydraulikzylinder werden auf diese Art im Wechsel bewegt und das Vorder- und Hinterrad an­ getrieben. Für Geschwindigkeitsänderungen kann der Hub an den Hydrau­ likzylindern stufenlos geändert werden. Kleiner Hub, geringe Geschwin­ digkeit, großer Hub, große Geschwindigkeit. Fig. 1 via the foot pedal ( 5 ), the piston of the hydraulic cylinder ( 1 ) is pressed in that pressure oil flows through the hydraulic lines ( 4 ) to the hydraulic wheel ( 7 ) and drives it. The flowing oil ( 9 ) is fed to the other hydraulic cylinder and lifts its piston. The piston rod with foot pedal extends. The hydraulic cylinders are moved alternately in this way and the front and rear wheels are driven. The stroke on the hydraulic cylinders can be changed continuously for speed changes. Small stroke, low speed, large stroke, high speed.

Eine Gangschaltung ist nicht erforderlich. Die Rückschlagventile (6) sperren den ausfließenden Ölstrom in diese Richtung.Gear shifting is not required. The check valves ( 6 ) block the oil flow in this direction.

Die Hydraulikleitungen werden durch den Hohlrahmen des Fahrrades ge­ führt und können so die Lenkbewegungen des Vorderrades mitmachen.The hydraulic lines are ge through the hollow frame of the bike leads and can participate in the steering movements of the front wheel.

Die Zuschaltung des Allradantriebes erfolgt mechanisch. Ein Ölkreis­ lauf wird gesperrt. Das Vorder- oder Hinterrad kann dann wahlweise angetrieben werden.The all-wheel drive is activated mechanically. An oil circuit run is blocked. The front or rear wheel can then optionally are driven.

Claims (1)

Hydraulisch angetriebenes Fahrrad mit zuschaltbaren Allradantrieb, stufenloser Geschwindigkeitsregulierung, dadurch gekennzeichnet, daß der Antrieb des Fahrrades über zwei, nebeneinander stehende Hydraulikzylinder (1) eingeleitet wird. Der durch die Beinkraft erzeugte hydraulische Druck treibt ein am Vorder- und Hinterrad angebrachtes Hydraulikrad (7). Die Hydraulikzyl. werden im Wechsel ein- und ausgefahren. Die geradlinige Bewegung der Hydraulikzylinder wird durch das Hydraulikrad in eine drehende Be­ wegung umgewandelt. Über zwei Kettenräder (3) werden die Räder des Fahr­ rades angetrieben.Hydraulically driven bicycle with switchable all-wheel drive, infinitely variable speed regulation, characterized in that the drive of the bicycle is initiated via two hydraulic cylinders ( 1 ) standing next to one another. The hydraulic pressure generated by the leg force drives a hydraulic wheel ( 7 ) attached to the front and rear wheels. The hydraulic cylinder. are moved in and out alternately. The straight-line movement of the hydraulic cylinders is converted into a rotating movement by the hydraulic wheel. The wheels of the driving wheel are driven by two chain wheels ( 3 ).
