Abstract

Bicycle provided with front-wheel drive, making it possible to replace the handlebars by a crank, the muscular force of the arms being added as a supplement to that provided by the legs on the ordinary pedals, characterized in that it includes: - an articulated support panel unit 1 rotates about the spindle 11 which supports all the front train and is articulated to the bike 9; - the fixed fork 2 with the unit 1. This fork carries the front wheel, on the spindle of which is fixed the small sprocket 5; the crank or connecting rod 3 which carries the hand pedal 4; at 6 there is the large sprocket which, by means of the chain 7, controls the small sprocket 5 keyed onto the front wheel 10.

Description

Bicyclette avec traction avant
Quand on est en bicyclette , la plupart des usagers ont du mal à monter les cotes trés raides et bien souvent descendent de vélo et marchent à pied 1' invention a pour but de remédier à cet inconvenient.Bicycle with front wheel drive
When you are on a bicycle, most users have trouble climbing very steep hills and very often get off the bike and walk on foot 1 invention aims to remedy this drawback.

Pour cela on ajoute une traction avant actionnant la roue avant à l'aide de manivelle chaine et pignon de cette façon on ajoute à 11 effort des jambes une puissance donnée par les bras.For this we add a front wheel drive actuating the front wheel using a chain and pinion crank in this way we add to 11 leg effort a power given by the arms.

la figure I est une vue schématique en élévation la figuez 2 est la vue en plan andessus du vélo la figure 3 est une vue de face devant le vélo sur la figure I on voit que le bloc tableau support I bloc articulé tourne autour de l'ave II (onze) qui supporte tout le train avar,t et s'articule avec le vélo 9 on trouve la fourche 2 fixe avec le bloc I
Cette fourche porte la roue avant sur l'axe de laquelle est fixé le petit pignon denté 5 la manivelle ou bielle 3 qui porte la pédale à main. 4 en 6 on a le grand pignon denté qui commande par l'intermédiaire de la chaine 7 le petit pignon denté 5 calé sur la roue avant IO sur la figure 2 on trouve en I le bloc support tableau en 5 les bielles ou manivelles e- 4 les L: :anivcllcs ou maneton à main en 6 le gnand pignen l'ensemble artioulé autour le l'axe II (onze) relié eu care de velo 9 figure 3
I le bloc articulé tableau support qui porte le grand 2 la fourche pignon 3 la bielle ou manivelle 4 la pédale à main 5-- le petit pignon 6 le grand pignon 7 la chaine 8 l'axe 9 le cadre ( non visible ) 10 la roue avant par exemple un vélo avec pédales simples développe 0,75 cheval
Si avec la traction avant on ajoute 0,35 cheval
Cela donne une puissance totale de I,IO cheveaux vapeur
soit facilement les 736 WATTS Figure I is a schematic view in elevation Fig 2 is the plan view andessus of the bike Figure 3 is a front view in front of the bike in Figure I we see that the support table block I articulated block rotates around the ave II (eleven) which supports the whole avar, t train and is articulated with the bike 9 we find the fork 2 fixed with the block I
This fork carries the front wheel on the axis of which is fixed the small toothed pinion 5 the crank or connecting rod 3 which carries the hand pedal. 4 in 6 we have the large toothed pinion which controls through the chain 7 the small toothed pinion 5 wedged on the front wheel IO in Figure 2 we find in I the table support block in 5 the rods or cranks e- 4 the L:: anivcllcs or crank pin by hand in 6 the big pin pin the whole articulated around the axis II (eleven) connected to the bike care 9 figure 3
I the articulated support table block which carries the large 2 the pinion fork 3 the connecting rod or crank 4 the hand pedal 5-- the small pinion 6 the large pinion 7 the chain 8 the axis 9 the frame (not visible) 10 the front wheel for example a bicycle with single pedals develops 0.75 horsepower
If with front wheel drive you add 0.35 horsepower
This gives a total power of I, IO steam horses
or easily the 736 WATTS
