Abstract

An electric motor (3) is secured to the bicycle front fork by a clamp mounting (4). The output shaft of the motor is fitted with a spur gear. This engages with a plastic or metal drive ring (1) with matching teeth fitted to the inside of the front wheel rim.

Description

Die Fahrradantriebsvorrichtung besteht aus einem Elektromotor mit einer Flachzahnscheibe auf der Motorwelle, und eines kreisförmigen Metallringes mit innenseitig geformten Flachzahnprofil, der im Radfelgenbereich befestigt wurde.The bicycle drive device is made an electric motor with a flat toothed washer on the motor shaft, and a circular one Metal ring with a flat tooth profile formed on the inside, in the wheel rim area was attached.

Bei dieser Fahrradantriebskonstruktion kann auf ein Übersetzungsgetriebe verzichtet werden; d. h. die Motorkraft wird direkt und verlustarm auf den Antriebsring aus Metall oder Kunststoff übertragen , der das Vorderrad in kraftvolle Drehbewegungen versetzt.With this bicycle drive construction can on a gearbox to be dispensed with; d. H. the motor power becomes direct and low-loss transferred to the metal or plastic drive ring of the front wheel set in powerful rotary movements.

Nachteile bei dieser Bauart entstehen, wenn noch ein Übersetzungsgetriebe zwischen E-Motor und Antriebsring zwischengeschaltet werden muß. Denn jede zusätzliche getriebliche Übersetzung bedeutet Übertragungsverluste der Antriebsleistung.Disadvantages arise with this design, if still a transmission gear must be interposed between the electric motor and the drive ring. Because any additional gear translation means transmission losses the drive power.

Die Aufgabe der Erfindung wird darin gesehen, eine Anordnung der anfangs genannten Bauart zu konstruieren, der den dargestellten Nachteil beseitigen soll.The object of the invention is therein seen to construct an arrangement of the type initially mentioned, which should eliminate the disadvantage shown.

Die Lösung der Aufgabe besteht erfindungsgemäß darin, dass die Kraftübertragung auf das Vorderrad nicht im Nabenbereich, sondern im Felgenbereich erfolgt. Hier zeigt sich der antriebstechnische Vorteil des Radfelgenantriebs gegenüber dem Nabenantrieb. Die Kraftübertragung an der Radfelge bedeutet eine energieeffizientere Leistungsumsetzung der Antriebskraft.According to the invention, the object is achieved by that power transmission on the front wheel not in the hub area, but in the rim area he follows. This shows the drive technology advantage of the wheel rim drive across from the hub drive. The power transmission on the wheel rim means more energy-efficient power conversion the driving force.

Aus der nachfolgenden Beschreibung und der skizzierten Darstellung des hybriden Antriebssystems in einer kombinierten muskel-elektrischen Antriebsform soll die Erfindung ausführlich erläutert werden.From the description below and the sketched representation of the hybrid drive system in The invention is intended to be a combined muscle-electric drive form in detail are explained.

1: Schematische Gesamtdarstellung des Fahrrades mit Antriebsvorrichtung; 1 : Overall schematic representation of the bicycle with drive device;

2: Perspektivische Teildarstellung der Antriebsvorrichtung in Form einer kombinierten Elektromotor/Antriebsringverbindung (mit Flachzahnprofil); 2 : Partial perspective view of the drive device in the form of a combined electric motor / drive ring connection (with flat tooth profile);

3: Schematische Gesamtdarstellung der Fahrradantriebsvorrichtung, bestehend aus Elektromotor mit Halterung an der Vorderradgabel und des Antriebsringes mit Flachzahnprofilierung im Radfelgenbereich; 3 : Schematic overall view of the bicycle drive device, consisting of an electric motor with a bracket on the front wheel fork and the drive ring with flat tooth profiling in the wheel rim area;

Wie aus den Darstellungen der drei Figuren zu ersehen ist, handelt es sich erfindungsgemäß um ein hybrides Antriebssystem für ein Fahrrad in Form eines muskel-elektrischen Doppelantriebes.As from the representations of the three According to the figures, it is a matter of the invention hybrid drive system for a bicycle in the form of a muscle-electric double drive.

Der elektromechanische Antrieb besteht aus dem Elektromotor 3 mit festsitzender Flachzahnscheibe 2 auf der Motorwelle. Das Antriebsrad 2 greift in die großprofilierte Flachzahnform, das auf der Innenoberfläche des Antriebsringes 1 plaziert ist. Der Antriebsring 1 kann aus Metall oder Kunststoff bestehen und ist fest im Radfelgenbereich mit dem Vordenad eines Fahnades verbunden.The electromechanical drive consists of the electric motor 3 with fixed flat toothed washer 2 on the motor shaft. The drive wheel 2 engages in the large-profile flat tooth shape on the inner surface of the drive ring 1 is placed. The drive ring 1 can be made of metal or plastic and is firmly connected to the front wheel of a wheel in the area of the wheel rims.

Das Material der Flachzahnform des Antriebsringes 1 ist aus hochbelastbaren Kautschuk mit Gewebe gefertigt. Störende Geräuschemissionen während der Fahrt werden auf diese Weise minimiert.The material of the flat tooth shape of the drive ring 1 is made of heavy-duty rubber with fabric. In this way, disturbing noise emissions while driving are minimized.

Als Vorteil erweist sich der einfache konstruktive Aufbau der Antriebsvorrichtung. Ein direkter Antrieb des Antriebsringes von Elektromotoren mit hohen Drehzahlen ist ohne Getriebe antriebstechnisch problemlos durchführbar.The simple one proves to be an advantage constructive structure of the drive device. A direct drive the drive ring of electric motors with high speeds is without Gearbox can be carried out without problems in terms of drive technology.

Die vergrößerte Verfügbarkeit und Bereitstellung von ausreichenden Kraftreserven bedeuten für den aktiven Fahrradfahrer mehr Mobilität und Fahrqualität.The increased availability and provision of sufficient power reserves mean for the active cyclist more mobility and driving quality.
