Abstract

This is a mechanism which makes it possible to regulate, as desired, the speed of rotation of a drive wheel of a bicycle between preset limits, the bicycle's transmission being chain transmission. The mechanism in question consists of a cylindrical body 1 mounted, like a conventional gearwheel (pinion), on the axle corresponding to the drive wheel of the bicycle, in which cylindrical body 1 is mounted, with the ability to move axially, a pair of plates 5 whose inner, facing surface is upwardly divergent, defining a channel in which is freely located a ring 9 with its periphery equipped with teeth 11 on which the corresponding transmission chain 12 meshes, which chain is guided on a gearwheel 17, as tensioning element, mounted on an articulated arm 16, whilst the disc 9 which constitutes the element of friction with the plates 5 and, definitively, the means for transmission of rotation to the drive wheel of the bicycle, in turn meshes with a fixed gearwheel 14 in order to prevent the rotation of the latter with respect to the plates 5, but allowing its axial displacement forwards and backwards in order to increase or reduce the transmission torque.
