ABSTRACT:
A speed variator pulley provided with reduced flexion removable rings is used in a variable speed transmission of the V pulley type, provided with a trapezoidal belt. Transmissions of this type are, for example, used in snow scooters, motorcycles, utilitarian or pleasure vehicles or cars without permit or of the TQM type. The pulley of the invention has an arrangement which makes it possible to reduce the axial friction forces which are the cause of a hysteresis effect in the operation of the pulley.
