Abstract: A modularly constructed pulley for a continuously variable transmission, provided with at least two discs on a pulley shaft and/or sleeve of the pulley shaft, one or more discs fixed as individual components to the pulley shaft and/or sleeve, and having at least one disc which is axially displaceable, by, e.g., a piston/cylinder assembly with pistons or cylinders individually fixed to the disc.

Abstract: The invention relates to a pulley, in particular for a continuously variable transmission, provided with two sheaves on a pulley shaft, the sheaves being non-rotationally fixable on the pulley shaft, and at least one sheave being axially movable relative to the pulley shaft by means of movement means.According to the invention, the movable sheave is placed on the pulley shaft in such a way that, if the movement means impose a stable position on the sheave, the sheave is fixed axially relative to the pulley shaft and that, if the movement means impose a change in the axial position of the sheave, the sheave is movable in the axial direction and/or in the direction of rotation relative to the pulley shaft.

Abstract: Pulley, in particular for a continuously variable transmission. The pulley is provided with two discs on a pulley shaft, at least one disc being axially movable relative to the other disc by means of control means. The movable disc is connected to the pulley shaft by means of a key/groove connection. A radially inward profile of the key/groove connection is connected to the disc, and a radially outward profile of the key/groove connection is connected to the shaft.
