Definitions

  • This invention relates to a multiple-speed cycle gear hub and to a cycle incorporating the same.
  • the touring cyclist particularly requires a wide overall range of gears with small changes of ratio between successive gears.
  • a normal Derailleur gear system can provide either a wide range or close ratios, but not both.
  • the drive input member On the opposite side of the flange 17 from the axial projection 15 the drive input member has a bearing section 20 which supports balls also running in contact with a support 22 screw threaded into the end of the hub casing 4 adjacent to the flange 3.
  • the hub casing is thus supported on the bearing section 16 in a manner allowing relative rotation between the two elements.
  • At least two pins 23, 24 project from the bearing section 16 into the hub casing. These pins engage within grooves or holes formed in a clutch member shown generally as 25 which is formed with four diametrically opposed radially outwardly projecting dogs, two of which are shown in the drawing, 26 and 27.
  • the clutch member is supported for rotation by a bearing 28 on a bush 29 surrounding and axially slidable on the axle 5.
  • a particularly convenient ratio is a 2:1 reduction, to achieve which the annular gear 41 will be formed with twice as many teeth as the sun wheel 34.
  • the rod 33 is released allowing the spring 30 to move the clutch 25 to the left as seen in the drawing, into a limit position wherein the pin 31 contacts the end of the slot 32.
  • the dogs 26, 27 of the clutch move out of engagement with the dogs 42, 43 of the annular gear and slide axially into a position where they engage the shafts 37, 38 carrying the planet wheels 35 and 36.
  • drive from the input member 16 is transmitted directly to the carrier 39, bypassing the gear train, and is thus transmitted directly to the hub casing 4 and the wheel.
  • the invention is applicable to cycle hubs which can be used in the drive assembly of any type of bicycle or tricycle.

Abstract

Un moyeu a pignons de cycle a plusieurs vitesses comprend un boitier de pignon (4) et un organe d'entree d'entrainement (16) dont une extremite se projette depuis le boitier. Cette extremite est adaptee pour recevoir un bloc de pignon de derailleur a dents multiples (19) qui comprend de preference son propre mecanisme de roue libre. Un organe d'embrayage (25) peut etre mis en rotation par l'organe d'entree d'entrainement (16) et peut coulisser axialement sur ce dernier entre des positions ou il entraine directement un porteur (39) fixe au boitier et ou il entraine le porteur par l'intermediaire d'un dispositif d'engrenage planetaire (34, 35, 36, 41). Le moyeu lui-meme est de preference depourvu de tout mecanisme d'encliquetage de roue libre et les pignons interieurs trouvant dans le moyeu sont en engrenement constant et leurs distances radiales ou axiales relatives ne sont pas modifiees pendant le fonctionnement du moyeu.
