Abstract
The invention relates to a clutch, particularly a multi-disk clutch, of an, in particular, manual transmission for, in particular, vehicles having a spring force of a spring device, said spring force influencing the adjusting force, which is produced in a power source and which serves to actuate the clutch. This clutch should be able to operated while maintaining predetermined closing and/opening times that are as precise as possible. In addition, the closing and/or opening times should be independent of possible changes in properties of the spring device. To this end, a clutch of the aforementioned type is characterized in that the spring device () and/or at least one of its thrust bearings is provided with a sensor (), which detects solid body changes and which serves to determine the spring force exerted by the spring device (), and a device for transmitting the determined measured values for controlling and/or regulating the adjusting power source.
