A speed variator for cars of the kind essentially comprising a variable-pitch-circle sheave and a belt and a driven sheave is improved by the provision of two driving half-sheaves which, with their respective driven half-sheaves, and the two belts compose the mechanical part of the variator. Hydraulic or mechanical provide necessary counteracting forces and are controlled by detectors and a transducing system so that the pitch circle diameters of the driving and the driven sheave can be controlled consistently with the variations of any preselected operative parameter of the engine or another part of the vehicle concerned.
