Abstract

In bicycles which do not have auxiliary motors, the energy produced when braking is lost. The eco-auxiliary motor stores this braking energy and, when the need arises, releases it and assists the manual power used when cycling. In order to store the excess energy produced when braking, the energy is transmitted to an energy-storing system (spring system) and stored via a friction wheel on the rear wheel of the bicycle. During forwards travel, on "stepping into the pedals", the energy which is needed is released from the energy store back to the bicycle. The flow of energy into the energy store and back takes place via a coupling system which is controlled automatically by bicycle mechanisms which are already in place (see Fig. 1). The special control and change-over via the chain tension ensures that the assisting action takes place without the cyclist also having to change gear. The eco-auxiliary drive does not replace the muscular power used when cycling but rather facilitates and assists cycling. The drive can be mounted on any bicycle or else retrofitted. <IMAGE>

Description

Am Hinterrad, etwa am Ort des Gepäckträgers, wird ein Hilfsmotor angebaut, der über ein Reibrad mit Kupplungssystem Fahrrad-Brems­ energie speichern und bei Bedarf wieder abgeben kann.At the rear wheel, for example at the location of the luggage rack, there is an auxiliary motor attached by a friction wheel with clutch system bicycle brake save energy and release it when needed.

Energie-SpeicherungEnergy storage

Bei einem Bremsvorgang werden eine oder mehrere Federn gespannt. Das Fahrrad verzögert und die Bremsenergie wird in gespeicherte Feder­ energie umgewandelt.One or more springs are tensioned during braking. The Bicycle decelerates and the braking energy is stored in spring energy converted.

Energie-AbgabeEnergy delivery

Tritt der Fahrer in die Pedale zum "Vorwärts-Fahren", d. h. er benötigt Energie, so wird die gespeicherte Energie über das Reibrad auf das Fahrrad wieder abgegeben.If the driver steps on the pedals to "drive forward", i. H. he needs Energy, so the stored energy on the friction wheel on the Bicycle returned.

LeerlaufNeutral

Bei Leerlauf, d. h. der Fahrer bremst nicht und tritt auch nicht in die Pedale, ruht das Energie-Speichersystem. Es wird weder Energie aufge­ nommen noch abgegeben.At idle, i.e. H. the driver does not brake and does not step into the Pedals, the energy storage system rests. Neither energy is consumed still given up.

UmschaltungenSwitching

Die Umschaltungen zur Energie-Aufnahme, zur Energie-Abgabe und zum Leerlauf erfolgen aus den sich vom "normalen" Radfahren ergebenden Bewegungsabläufen, d. h. keine zusätzlichen Schaltungen.The switches for energy consumption, energy delivery and Idling occurs from those resulting from "normal" cycling Movements, d. H. no additional circuits.

Es wird der Effekt ausgenutzt, daß sich beim "Vorwärtsfahren, in die Pedale treten" die Kette oben spannt und unten schlaff wird. Umgekehrt wird beim "Rücktritt" die Kette unten stramm und oben schlaff.The effect is exploited that when driving "forward, into the Pedaling "tensions the chain at the top and slackens at the bottom. Vice versa the chain becomes tight at the bottom and slack at the top when you step back.

Um diesen Effekt zu Schaltvorgängen auszunutzen, werden im Zwischen­ raum der Fahrradkette Kettenräder (Ritzel) angebracht, über die die Fahrradkette geführt wird. Wird nun der Kettenstrang wechselnd oben oder unter stramm oder schlaff, oder beidseitig schlaff, so wird die daraus resultierende Kettenwegung als Schaltvorgang umgesetzt.In order to take advantage of this effect for switching operations, in between Space of the bicycle chain chain sprockets (sprocket) attached over which the Bicycle chain is guided. Now the chain strand is alternately at the top or under tight or limp, or flaccid on both sides, so the resulting chain movement implemented as a switching process.

Schaltzusatz bei Fahrrädern ohne RücktrittsbremseGear change on bicycles without a coaster brake

Bei Fahrrädern ohne Rücktritt wird der Bremszug der Hinterrad- Handbremse als "Energie-Speicher-Befehl" mitbenutzt.On bicycles without back pedaling, the brake cable on the rear wheel Handbrake used as "energy storage command".

Claims (3)

Es wird Patentanspruch erhoben auf eine Vorrichtung, die es ermöglicht, die beim Bremsen entstehende Energie zu speichern und beim "in die Pedale treten" benötigte Energie als unterstützende Kraft abzugeben,
gekennzeichnet dadurch, daß die Schaltvorgänge zum Energie-Speichern oder zum Energie-Abgeben oder zum Leerlauf keine zusätzlichen manuellen Schaltvorgänge erforderlich sind, sondern daß diese Schalt- Informationen über die beim Fahrradfahren entstehenden Ketten­ spannungen und vorhanden Handbremsen ausgelöst werden.There is a claim to a device that makes it possible to store the energy generated during braking and to deliver the energy required when “pedaling” as a supporting force,
characterized in that the switching operations for storing energy or for releasing energy or for idling no additional manual switching operations are required, but that this switching information about the chains arising during cycling and existing hand brakes are triggered. Bei Fahrrädern ohne Rücktritt findet die Schaltung zur Energie­ speicherung ebenfalls ohne zusätzliche Schaltvorgänge statt; In diesem Fall wird der Zug der Hinterrad-Handbremse gleichzeitig als Umschalter zur Energiespeicherung herangezogen.With bicycles without resignation, the circuit for energy takes place storage also takes place without additional switching operations; In this In this case, the rear wheel handbrake train is also used as a changeover switch used for energy storage. Mit diesem Öko-Hilfsmotor wird das Fahrradfahren erleichtert, weil vom Fahrer unbemerkt ein ständiger Energieaustausch zugunsten des Fahrrad­ fahrers stattfindet, ohne daß zusätzliche Fremdenergien (Kraftstoffe u.ä.) zugeführt werden müssen.With this eco auxiliary motor, cycling is made easier because of Riders unnoticed a constant energy exchange in favor of the bike driver takes place without additional external energies (fuels etc.) must be fed.
