BeschreibungDescription

Kettenantrieb für Fahrrad - Vorderrad (Allrad)Chain drive for bicycle - front wheel (four-wheel drive)

Die Erfindung betrifft einen Kettenantrieb für ein Fahrrad - Vorderrad.The invention relates to a chain drive for a bicycle front wheel.

Die Kraftübertragung erfolgt mittels einer Ax - Parallel Drehkurbel (Pos.2), welche zugleich als Lenkstange dient, über eine zwangegeführte Kette (Pos.3). Mittels Lcrlaufkettenrad, welches ikit Federkraft angepresst ist (Pos.5) wird die Kette gespannt. Das Vorderrad ist mit einer Freilauf - Rücktrittsbremsnabe ausgerüstet (Pos.4).The power is transmitted by means of an Ax-parallel crank (item 2), which also serves as a handlebar, via a force-guided chain (item 3). The chain is tensioned by means of a freewheel sprocket, which is pressed on by spring force (item 5). The front wheel is equipped with a freewheel coaster brake hub (item 4).

Bei einem handelsüblichem Fahrrad wird nur die Muskelkraft unterhalb der 3ürtel!inie genutzt. Mit einem Vorderradantrieb über Ax - Parallel - Drehkurbel wird die Muskelkraft der Arme und die Gewichtsverlagerung des Oberkörpers genutzt. Extreme Bergfahrten sind leichter als mit handesüblichen Fahrrädern auszuführen. Ferner kann das Fahrrad mit Vorderradantrieb als Trainingsgerät für Sportler eingesetzt werden.With a standard bicycle, only the muscle power below the belt line is used. With a front-wheel drive via an Ax-parallel crank, the muscle power of the arms and the weight shifting of the upper body are used. Extreme mountain rides are easier than with standard bicycles. Furthermore, the bicycle with front-wheel drive can be used as a training device for athletes.
