  • FIGS. 3 and 4 show a construction which differs greatly in the front part from the subject of the invention. Another difference is that in this known bike, the two people are seated next to each other rather than one behind the other.
  • a further development of the invention consists in that the first part consists essentially of three in the right There are walls arranged at an angle to one another, of which the middle first wall runs approximately vertically and carries the first gear, the second wall runs approximately horizontally at the top and carries parts of the link bearing and the third wall runs approximately horizontally below and carries parts of the fork bearing.

Abstract

L'invention concerne un véhicule à deux ou à trois roues avec ou sans moteur pour une personne ou pour deux personnes situées l'une derrière l'autre, qui comprend une roue avant, une roue arrière ou deux roues arrière, un cadre avec une selle, un entraînement, notamment une manivelle de pédalier, un premier pignon situé sur le cadre, en bas, entre la roue avant et la (les) roue(s) arrière, une première chaîne d'entraînement entourant ce premier pignon, une première partie située sur le cadre dans laquelle se trouvent, en haut, un guidon et, en bas, une fourche de roue avant, une seconde partie reliant la partie support solidaire du guidon et la partie support solidaire de la fourche, un second pignon monté rotatif sur la première partie et sur lequel la première chaîne passe et un troisième pignon situé en bas à l'avant, qui est entouré par une chaîne et qui entraîne la roue avant. L'invention se caractèrise en ce que la première et la seconde partie se trouvent chacune d'un côté de l'axe de pivotement commun du support de la fourche et du support du guidon; un quatrième pignon (10) est monté rotatif sur la seconde partie faisant face au second pignon (9); ces deux pignons (9, 10) sont reliés l'un à l'autre par l'intermédiaire d'un arbre qui comprend un joint articulé se trouvant sur l'axe de pivotement du support de la fourche et du support du guidon; une seconde chaîne (11) entoure également le troisième et le quatrième pignon (12, 10). L'invention permet par conséquent d'éviter que les chaînes ne sortent des pignons ou ne se déplacent sur ceux-ci, par mouvement latéral, lorsque le guidon pivote.
