Improvements in the progressive speed change systems characterized by the fact of forming the pulleys of variable motor diameter and coinciding by separate sliding conical plates along their respective axes driven by an external compensating control device that allows to bring closer those of a pair while separating those from the opposite; because the surface of these plates present a radial groove from the axial base to the peripheral one; to solve the flexible element of transmission between one and another pulleys by a metal chain of complex links whose essentiality lies in that each link forms a transverse ring in which wrapped by an elastic sleeve fits a pack of steel straps perpendicular to the direction of movement of the chain and whose ends protrude sufficiently on each side of the chain to fit and mesh with the radial grooves of the plates.
