Abstract
An actuating system for at least first and second coaxially arranged shifting elements of a transmission, in particular, a dual-clutch transmission () with at least two coaxially arranged control devices for actuating the associated shifting elements. The control devices comprise at least one rotary drive () and at least one control element () which are coupled to one another by corresponding gearteeth such that rotational movement, of each rotary drive (), can be converted into an axial control movement of the associated control element (). The axial position of the teeth of the geartooth array, of each control element (), varies in the circumferential direction, at least over a certain range.
