Definitions

  • Figure 1 of the drawings is a perspective view from above of a gearing arrangement 10 in accordance with a preferred embodiment of the present invention.
  • the illustrated embodiment is intended for use in a relatively low power machine, such as a bicycle or moped and includes a housing 10 which provides mounting for a rotating input member 14 and a rotating output member 16.
  • the housing 10 is illustrated as being open, however it will be recognised that the housing would normally enclose and protect the inner workings of the arrangement .

Abstract

L'invention concerne un agencement d'engrenages (10) permettant des changements de rapports de vitesses sans à-coups. Dans le mode de réalisation décrit, ledit agencement d'engrenages (10) comprend un certain nombre de leviers (30, 31, 32, 33) couplés au niveau de leurs axes pivotants à un élément de sortie (16) rotatif via des embrayages unidirectionnels (34) respectifs. Lesdits leviers (30, 31, 32, 33) sont également couplés à un élément d'entrée (14) rotatif au moyen d'un agencement de came et de poussoir de came, de sorte que le mouvement rotatif de l'arbre d'entrée (14) entraîne le mouvement des leviers (30, 31, 32, 33) autour de leurs axes pivotant et entraîne donc la rotation de l'arbre de sortie (16). La distance entre l'arbre de sortie (16), et donc les axes pivotant des leviers (30, 31, 32, 33) à partir de l'agencement de came et de poussoir de came est variable, ce qui permet de modifier le rapport de vitesses.
