BeschreibungDescription

Reibradantrieb, insbesondere zum Antrieb von Fahrrädern, 3-Räder, Krankenfahrstühle u. Boots-SlipwagenFriction wheel drive, especially for driving bicycles, 3-wheelers, wheelchairs and boat launching trolleys

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 Ein-Reibrad ist in der Regel auch ein Getriebe notwendig, d.h. das Ein-Reibrad sollte mind. 50 mm Durchmesser haben, um die Kraft vernünftig aufs Rad zu bekommen. Selbst dann steht durch eindrücken des Ein-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. With a single friction wheel, a gearbox is generally also necessary, i.e. the single 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 single 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 von 2 oder mehreren hintereinander angeordneten Reibrädern, welche mit gleicher Umfangsgeschwindigkeit laufen und über eine Kette oder Riemen bzw. Zahnriemen miteinander verbunden sind und synchron laufen eine doppelt oder mehrfach größere Auflagefläche entsteht und der Reifen sicherer u. weitgehend schlupffrei bei geringerem spezifischem Anpreßdruck mitgenommen wird.The invention achieves that by using 2 or more friction wheels arranged one behind the other, which run at the same circumferential speed and are connected to one another via a chain or belt or toothed belt and run synchronously, a contact surface that is twice or several times larger is created and the tire is carried more safely and largely without slippage at a lower specific contact pressure.

dadurch gekennzeichnet,2. Drive according to claim 1
characterized, daß im Gegensatz zu einem einfachen ein-Rollenantrieb durch 2 oder mehrere hintereinander angeordnete Rollen eine größere Auflagefläche auf dem Reifen entsteht und diesen sicherer mitnimmt und bei geringerem spezifischem Auflagedruck geringere Einschleifspuren hinterläßt. that in contrast to a simple single-roller drive, two or more rollers arranged one behind the other create a larger contact surface on the tire and move it more securely and, with a lower specific contact pressure, leaves fewer grinding marks. 3. Antrieb dadurch gekennzeichnet, daß er aus3. Drive characterized in that it consists of Leerlaufstellung nach aufsetzen auf den Reifen diesen weicher und sicherer mitnimmt.Neutral position after placing on the tire moves it more smoothly and safely. 4. Antrieb dadurch gekennzeichnet,4. 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 oder Jalousieführung 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 rotary handle and engages in the lifted position via a latch or blind guide (idle).
