Definitions

  • the motion of the pedal crank makes spin both the pin (A) and the train holder unit (C) linked to it.
  • the link between pin (A) and unit (C) is achieved by means of a thounsandtooth jawclutch.
  • On the train-holder unit (C) are placed some planetary gears (D)(6 in the given example) which turn round pin (E).
  • These planetary gears (D) start turning round by means of tha motion of (C) and since they find a hinder in the fixed crown gear (F), they make the ring gear (G) turn round.
  • this ring gear (G) is linked to a cylinder front sprocket wheel holding axle whict turn round axle (A).
  • Cap (K) is fixed to the bicycle frame for example by means of a hinder (S) (as shown in fig. 3), whict prevent the cap itself from turning round.
  • S hinder
  • Two groups of little balls (L1) and (L2) are placed in the space obtained from the special shape of axle (A) and from cap (K).

Abstract

Train multiplicateur épicycloïdal ayant une tige (M) d'entraînement creuse placée dans le logement de l'arbre de pédale. Les engrenages planétaires (D) sont entraînés au moyen de tiges d'entraînement (E) bloquées par une couronne à denture (F) fixe, et déplacent à la fois une couronne planétaire (G) et les grands pignons avant lui étant reliés. Les pièces d'introduction (A) de l'arbre de pédale sont coniques et ont une vis de serrage.
