Definitions

  • the invention detailed in this document concerns the development of a new rear wheel hub for assisting the propulsion of cycles both in the sports arena and domestic use.
  • the outer hub rotates as normal on the central axis pin. This is then connected to an inner hub via a torsion spring. This spring stores energy generated through each pedal stroke which is then released at the point when the pedal stroke diminishes during the 'dead point'.
  • An inner hub is connected via the torsion spring to an outer hub on which the gear wheels are fixed.
  • the inner and outer hubs are connected with bearings allowing the torsion spring to move independently from the outer hub.
  • a torsion spring is fixed in the centre of the inner hub with a lever anchored at an angle to the axle, another lever rests on a buttress screw on the outer hub.
  • the torsion spring which strains and relaxes, allows movement of the inner hub independently of the outer hub and thus abolishes the dead point of the driving gear.
  • Fig. 2 side section of the rear wheel hub
  • Fig. 3 partial section with a review of the set up of spring levers (8, 11 ).
  • the inner hub (1 ) is connected via the torsion spring (7) to the outer hub (3) on to which the gear wheels are attached (2).
  • the inner and outer hubs are connected with the use of bearings (6) which allows the torsion spring (7) to operate independently from the outer hub.
  • the torsion spring (7) connects with the centre of the hub via a lever which is anchored at a suitable angle onto the axle (5) with a groove in the inner hub and another lever (11) which leans onto the buttress screw (10) on the outer hub (1).
  • the inner and outer hubs are connected via a torsion spring (6) which strains and relaxes while allowing movement of the inner hub (3) independently of the outer hub (1 ) and thus the dead point of the driving gear is abolished.
  • the torsion spring (7) is primed with the forward motion of gear wheel (2).
  • the inner hub (3) starts to push over the buttress screw (10) while the outer hub (1) connects to the lever (8).
  • the inner hub (3) connected in the opposite direction as the gear wheel is turned.
  • the torsion spring (7) is unwound during the pedalling of the driving gear until the point of the dead point.
  • the torsion spring which has engaged with the lever (8) and anchored into the groove (9) of the inner hub, begins to release its kinetic energy against the buttress screw (10) which is fixed on to the outer hub (1) and gives continued forward motion eliminating the dead point.
  • the driving force is given by the accumulated kinetic energy in the torsion spring which drives the outer hub for the period of the dead point.

Abstract

L'invention révèle des détails relatifs à la mise au point d'un nouveau moyeu de roue arrière qui facilite la propulsion des cycles aussi bien dans le domaine du sport que celui de l'usage domestique, appelé 'E-HUB'. Le problème technique résolu par le moyen 'E-HUB'' est celui du 'point mort', c.-à-d., la période au cours du pédalage dans laquelle la puissance de propulsion avant chute sous l'effet du contact du mécanisme d'entraînement de la bicyclette (voir figure 1). La conception d'un moyeu mobile permet d'atteindre une vitesse plus élevée et un élan plus constant avec la même rendement énergétique de la part du cycliste. Le moyeu intérieur (3) pivote normalement autour du rivet d'axe central (5). Celui-ci est ensuite relié à un moyeu extérieur (1) via un ressort de torsion (7). Ce ressort (7) accumule l'énergie produite à chaque coup de pédale et la libère lorsque le coup de pédale diminue au cours du 'point mort'.
