  • the bicycle frame is suitable for bicycles, as a traction mechanism as
  • the bicycle frame can be made foldable for the construction of folding wheels by design only with great effort.
  • Sprocket by means of a separate dropout (for example, by means of the extruded profile provided here for receiving the seat tube) are arranged so far below the frame tube pair that it does not cut the bicycle frame, and the upper chain strand must still be performed below the bicycle frame through the output sprocket can cut without the bicycle frame.
  • Frame side parts known, wherein the frame side parts can be carried out as extruded profiles, which are connected in the middle with spacer elements.
  • This bicycle frame has the disadvantage that it consists of at least two frame side parts and separate spacers are provided between the two frame side parts.
  • Bottom bracket housing is very close to the bottom bracket shell, so this connection must be made very stable due to the bending moment loads occurring there.

  • Rear struts are provided with grooves in which the rear wheel axle with the
  • Rear struts is attached.
  • a disadvantage of this bicycle frame is that the inclusion of the rear wheel and the positioning of the bottom bracket is only achieved by the fact that the individual segments of the extruded profile must be bent, which is associated with high manufacturing costs and thus the individual segments are significantly weakened in their strength.
  • Bicycles and bicycle frames which provide a lying outside the bicycle frame drive sprocket and a lying between the bicycle frame and rear driven sprocket, have the disadvantage that the two rear struts of the bicycle frame seen from the bottom bracket must extend outward and thus can not run parallel. The resulting manufacturing effort is correspondingly high.

Abstract

L'invention concerne un cadre de bicyclette (1) constitué d'un profilé creux extrudé, qui est divisé en deux segments extérieurs (1c, 1d) et un segment intérieur (1e) par deux parois intérieures (1a, 1b) s'étendant de la face supérieure à la face inférieure du cadre de bicyclette et qui est destiné à être relié à un système d'entraînement arrière (3), comprenant un pignon mené (5) d'un mécanisme de transmission à lien souple ou par engrenage, une roue arrière (2) et un arbre de roue arrière (4) entraîné par le pignon mené et entraînant la roue arrière, le système d'entraînement arrière étant relié à au moins un bras (1f) du cadre de bicyclette, lequel est formé par un segment extérieur. Le cadre de bicyclette est caractérisé en ce que le bras et les éventuelles pattes arrière reliées au bras sont placés sur l'arbre de roue arrière entre le pignon mené et le siège (4a) de la roue arrière, vus dans le sens axial, et en ce que les deux segments extérieurs et le segment intérieur du cadre de bicyclette s'étendent parallèlement les uns aux autres sur toute leur longueur. L'avantage est que les pignons menant et mené du système d'entraînement de la bicyclette sont agencés sur le même côté extérieur du cadre de bicyclette, ce qui permet d'utiliser aussi bien une transmission à courroie qu'une transmission par engrenage.
