ABSTRACT:
A variable speed drive pulley, especially for automobile vehicles, comprises coaxial first and second pulley flanges which rotate with a hub and are in axial face-to-face relationship to receive a belt between them. At least the first pulley flange is a mobile pulley flange slidably mounted on the hub with radial clearance. It is thus movable along the hub between two extreme configurations, in at least one of which a primary bearing surface on the mobile pulley flange is in axial face-to-face relationship with a secondary bearing surface. An anti-friction member is disposed axially between the primary and secondary bearing surfaces.
