A twin clutch, in particular an actively closing, dry friction twin clutch is provided for a twin clutch transmission of a motor vehicle having an internal combustion engine, a crankshaft, and two transmission input shafts. The ring bearing comprises an upper casing, a lower casing, and a plastic ring engaged between the upper and lower casings, thereby forming said ring bearing. In this manner, event execution is not dependent on other processes in the network and the simulation can actually be carried out at speeds faster than real time. The stop mechanism is preferably configured such that relative axial movement between the guidewire and the outer shaft may be selectively precluded. Further, the storing of the plurality of predetermined tonal values is performed prior to the receiving of the plurality of input values.
