摘要： The invention relates to an actuating device (10) for introducing actuating forces into a friction clutch device in order to actuate at least one friction clutch arrangement of the friction clutch device in the spirit of engagement or disengagement, and to a torque transmission device comprising such an actuating device for transmitting torque in a drive train of a motor vehicle between a drive unit and a transmission, said torque transmission device additionally comprising the friction clutch device. The invention further relates to a method for assembling such a torque transmission device. Different aspects of the invention relate to the setting of an initial load on at least one engagement bearing or release bearing (18, 30) of the actuating device, to the setting of an over-center configuration for at least one compensating spring associated with at least one rotating member (22; 14) of the actuating device, the setting of a rotational adjustment range of the rotating member and/or an axial adjustment range of an axially adjustable actuating member (22; 14) based on a rotational motion provided for the rotating member, to the achievement of an NC characteristic in the case of an NO friction clutch arrangement, or an NO characteristic in the case of an NC friction clutch arrangement by the compensating spring, and to advantageous design solutions relating to the actuating device.

摘要： 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.
