Definitions

  • gears on the axis may optionally be provided a gear nut on the axis or the thread
  • the distance between the two planes of the first gear and thus the distance of the two gears to each other is on the width of the transmission means
  • both chainrings 130 and 140 have the same opening diameter.
  • the thread 120 is likewise stepped, the lower second chainring 140 rests on the step and the first chainring 130 cohesively engages the second chainring 140

Abstract

La présente invention concerne une roue dentée (130) destinée à un engrenage d'une bicyclette, un engrenage muni de ladite roue dentée (130), ainsi qu'une bicyclette munie de ladite roue dentée (130) ou dudit engrenage. Selon l'invention, la roue dentée (130) présente un premier plan (180) et un second plan (190), les dents de la roue dentée étant agencées dans le premier plan (180) et la fixation (200) de la roue dentée (130) étant réalisée au niveau d'un axe ou d'un moyeu (110) de la bicyclette. L'aspect essentiel de l'invention réside en ce que les deux plans (180, 190) sont à distance l'un de l'autre.
