摘要

Improved pulley for speed variator, with pulleys and trapezoid belt of the type comprising a pulley hub, a disk mounted fixed axially on the hub and a mobile disk in axial translation along the hub, characterized by carrying mounted on the hub of the pulley a set of springs disposed in star, which drive the mobile disk so that it is centered with respect to the fixed and hub and that exerts an appropriate pressure on the trapezoidal belt and by having several pairs of lever of each pair articulated on it. The fixed disk, coupled mutually by one end and joined by the other to the mobile disk, so that the latter moves while remaining parallel to the fixed disk.
