Abstract

In a variable speed transmission of the pulley type, one of the pulley cheeks is movable axially with respect to the other which is stationary. The movable cheek faces a reaction cup which is solid with the stationary cheek. The cup and the movable cheek are formed with converging cam surfaces which define between them a chamber into which are disposed centrifugal weights having ends sliding on the cam surfaces. When the pulley and reaction cup rotate, the weights are thrown outward and force the movable cheek toward the stationary one.
According to the invention, the cam surface of the reaction cup is concave, having a radius of curvature of predetermined length. On the other hand, the end edges of the centrifugal weights slidable on the cam surface of the reaction cup are convex and have a radius of curvature shorter than said predetermined length so that the ends of the weights bear only on a limited part of the cam surface of the reaction cup.
