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