Abstract

La présente invention se rapporte à un appareil d'accélération de bicyclette destiné à accroître la vitesse de roulement de la bicyclette. L'appareil d'accélération de bicyclette selon l'invention comprend : une paire de pédales (110) dont chacune est accouplée à un bras (111), pour l'exécution d'une opération de pédalage ; des arbres rotatifs (120) dont chacun est respectivement accouplé aux deux extrémités d'un bras (111) de la pédale (110) ; un tube de guidage (130) destiné à recevoir et à guider l'arbre rotatif (120) qui le traverse ; un boîtier (140) accouplé à un côté du tube de guidage (30) ; un bloc d'engrenages d'accélération (150) qui comprend une roue planétaire (151) clavetée sur l'arbre rotatif (120) et une pluralité de pignons satellites (153) montés équidistants autour de la roue planétaire (151) et en prise avec celle-ci, chaque pignon satellite (153) comprenant deux roues d'engrenage et une roue d'engrenage de petit diamètre ayant un plus petit nombre de dents qui est en prise avec la roue planétaire (151) pour coopérer avec elle ; et une roue à chaîne (160) qui comprend un engrenage de transmission de puissance (161) destiné à être mis en prise avec l'autre roue d'engrenage de grand diamètre, qui possède un plus grand nombre de dents que les pignons satellites (153) qui sont disposés concentriquement à la roue planétaire (151) du bloc d'engrenages d'accélération (150), et qui tourne autour de l'arbre rotatif (120). Lorsqu'un appareil d'accélération est monté sur les arbres rotatifs qui tournent en réponse à une opération de pédalage de la bicyclette, la force de rotation de la roue à chaîne résultant de l'opération de pédalage est doublée et la vitesse de la bicyclette peut aussi être au moins deux fois plus rapide. En outre, étant donné que l'appareil d'accélération peut être facilement incorporé dans l'arbre rotatif, même de petites bicyclettes peuvent bénéficier de ses performances d'accélération.
