Title (EN) APPARATUS FOR CHANGING SPEED BETWEEN TWO PARALLEL SHAFTS
(FR) APPAREIL PERMETTANT DE CHANGER DE VITESSE ENTRE DEUX ARBRES PARALLÈLES
Abstract: front page image
(EN)An apparatus (1000) for changing speed between two parallel shafts ((X), (J)) of a bicycle, for example. The apparatus (1000) includes a speed-change device (100; 100*; 100**), and a speed-change mechanism connected mechanically to the speed-change device (100; 100*; 100**). The apparatus (1000) is characterized in that the speed-change device (100; 100*; 100**) has two arc-shaped flexible members ((BNL1); (BNL2)) on which a chain rests. And the radius of curvature ((R1); (R2) ) of the two arc-shaped flexible members ((BNL1); (BNL2)) can be user-adjusted by operating actuating devices controlled by the speed-change mechanism, to achieve the desired velocity ratio of the two shafts ( (X), (J) ).
(FR)L'invention concerne un appareil (1000) permettant de changer la vitesse entre deux arbres parallèles ((X), (J)), d'une bicyclette, par exemple. L'appareil (1000) comprend un dispositif de changement de vitesse (100; 100*; 100**) et un mécanisme de changement de vitesse relié mécaniquement au dispositif de changement de vitesse (100; 100*; 100**). L'appareil (1000) se caractérise en ce que le dispositif de changement de vitesse (100; 100*; 100**) présente deux éléments souples en arc de cercle ((BNL1); (BNL2)) sur lesquels repose une chaîne. Le rayon de courbure ((R1); (R2) ) des deux éléments souples en arc de cercle ((BNL1); (BNL2)) peut être ajusté par l'utilisateur au moyen de dispositifs d'actionnement commandés par le mécanisme de changement de vitesse, afin d'obtenir le rapport de vitesse souhaité des deux arbres ( (X), (J) ).
