Abstract: An actuating device for applying actuating forces in a friction clutch device for engaging and disengaging a friction clutch assembly of the friction clutch device. The torque transmission device comprises the actuating device for transmission of torque between a drive unit and a transmission which also includes the friction clutch device. A method for installing a torque transmission device of this type. Various aspects relate to setting of a pre-load on a bearing of the actuating device, setting an over-dead-point configuration for a compensation spring associated with at least one rotary member of the actuating device, setting a rotation movement range for the rotary member and/or an axial movement range for an actuating element which can be displaced axially by rotation movement imparted to the rotary member, and producing either a normally engaged or disengaged characteristic in a normally-engaged or normally-disengaged friction clutch assembly with the compensation spring.

Abstract: An actuating system for at least first and second coaxially arranged shifting elements of a transmission, in particular, a dual-clutch transmission (1) with at least two coaxially arranged control devices for actuating the associated shifting elements. The control devices comprise at least one rotary drive (4, 5) and at least one control element (6, 7) which are coupled to one another by corresponding gearteeth such that rotational movement, of each rotary drive (4, 5), can be converted into an axial control movement of the associated control element (6, 7). The axial position of the teeth of the geartooth array, of each control element (6, 7), varies in the circumferential direction, at least over a certain range.

Abstract: A method of blocking inadmissible gearshift processes in a transmission with a plurality of shifting devices which, in order to carry out a shift process, are moved by actuating devices when a shift command is sent by a control unit to the relevant actuating device. The actuating devices exchange data with one another and the control unit such that the actuating device of the shifting device to be shifted is activated only if clearance is given by at least another actuating device. In a transmission with a control unit and a plurality of actuating devices for the actuation of shifting devices, the actuating devices are associated with at least one shaft and connected for data exchange with one another and with the control unit such that the actuating device of the shifting device to be shifted can be activated provided that clearance has been given by at least one other actuating device.
