Description

BeschreibungDescription

Riemenantrieb, insbesondere zum Antrieb von FahrrädernBelt drive, especially for driving bicycles

Stand der TechnikState of the art

Antriebe üblicher Technik sind entweder starr, d.h. sie erfolgen über eine Kette oder Kardanantrieb oder Schneckenantrieb direkt, oder über ein Reibrad.Drives using conventional technology are either rigid, i.e. they are operated directly via a chain or cardan drive or worm drive, or via a friction wheel.

Problemproblem

Bei Antrieben über Ketten, Kardan oder Schnecken ist ein größerer technischer Aufwand nötig (Getriebe) u. der Wirkungsgrad ist in der Regel relativ schlecht. Beim Reibrad ist in der Regel auch ein Getriebe notwendig, d.h. das Reibrad sollte mind. 50 mm Durchmesser haben, um die Kraft vernünftig aufs Rad zu bekommen. Selbst dann steht durch eindrücken des Reibrades auf den Reifen, nur eine geringe Kraftübertragungsfläche zur Verfügung u. es entsteht erheblicher Schlupf.Drives via chains, cardans or worms require a greater technical effort (gearbox) and the efficiency is generally relatively poor. A gearbox is generally also necessary for friction wheels, i.e. the friction wheel should have a diameter of at least 50 mm in order to get the power to the wheel properly. Even then, by pressing the friction wheel onto the tire, only a small power transmission surface is available and considerable slip occurs.

Erfindung
Diese Probleme werden mit der Maßnahme des Anspruchs 1 gelöst. invention
These problems are solved by the measure of claim 1.

Vorteilhafte Wirkung der ErfindungAdvantageous effect of the invention

Mit der Erfindung wird erreicht, daß durch Einsatz eines Reibriemens über einer größeren Fläche des Reifens, dieser nach absenken des Antriebes u. des Riemens auf den Reifen, sicher u. weitgehend schlupffrei mitgenommen wird.The invention achieves that by using a friction belt over a larger surface of the tire, the tire is carried safely and largely without slippage after the drive and the belt are lowered onto the tire.

Claims (3)

SchutzanspruchClaim for protection 1. Hilfsantrieb über Rückseite eines Zahnriemens oder1. Auxiliary drive via back of a toothed belt or Rillen oder Keilriemen direkt auf Vorder- oder Hinterrad eines FahrradesGrooves or V-belts directly on the front or rear wheel of a bicycle dadurch gekennzeichnet,characterized, daß der Riemen an einem Drehpunkt nach unten aufthat the belt is pivoted downwards to das Rad geschwenkt wird u. dieses antreibt.the wheel is swiveled and drives it. 2. Riemen nach Anspruch 1
dadurch gekennzeichnet,2. Belt according to claim 1
characterized, daß er im Gegensatz zu einem Rollenantrieb über einer größeren Fläche des Reifens aufliegt u. diesen sicherer mitnimmt u. auch keine Einschleifspuren hinterläßt.that, in contrast to a roller drive, it rests over a larger area of the tire and moves it more securely and leaves no traces of wear. 3. Antrieb bzw. Riemen dadurch gekennzeichnet,3. Drive or belt characterized by daß er aus Leerlaufstellung nach aufsetzen auf den Reifen, diesen weich, d.h. kupplungsartig mitnimmt.that from the neutral position after touching the tire, it takes it along smoothly, i.e. like a clutch. Antrieb dadurch gekennzeichnet,Drive characterized by daß er mit Gewichts- oder Federkraft auf das Rad gedrückt wird u. über Hebel oder Drehgriff abgehoben werden kann u. über eine Klinke im abgehobenen Zustand einrastet (Leerlauf).that it is pressed onto the wheel by weight or spring force and can be lifted off using a lever or twist grip and engages via a latch when lifted off (idle).
