- the wet room will be filled only with a small amount of a viscous medium.
- the viscous medium such as oil or a fat emulsion serves to minimize friction and minimize wear.
- the wet space is characterized in that it is filled with oil or another viscous medium, so that there recorded in the wet room components that advantageously comprise a gear arrangement, run in an oil bath and / are flowed through by a directed flow of oil.

- the separating clutch is adapted to direct the torque or torque components from the input area to the output area.
- the separating clutch can be designed so that it is not only used as an open-close clutch, but also finds application as a slip clutch. This means that the clutch does not pass the entire speed from the engine to the transmission input shaft.

- FIG. 1 shows an illustration of a torque transmission arrangement according to the invention
- FIG. 1 shows a torque transmission assembly 1 for an automated hybrid transmission 2.

- This structural embodiment is necessary in some drive concepts known to guide the drive shaft through the first space area.
- the first torsional damper 10 can be operated with a grease filling and is preferably placed in the drying space 24, in which no viscous medium is contained.
- the second torsion damper 20 is integrated in the second space region 19 and is thus located in the moist space 26, which is an oil mist-containing, but not filled with oil working space. Between the two torsion dampers 10, 20 a speed-adaptive absorber 6 is arranged. This is also located in the oil mist wet space 26th

- the two cover plates 88 and to an inner disk carrier 27 of a separating clutch 14 are joined together.
- the cover plates 88 may have a double S-shaped impact geometry in cross-section. In this way, a spreading movement due to centrifugal force and radial spring system is counteracted at high speeds.
- a ratio between the outer diameter of the cover plates 88 and the rotor carrier diameter can be designed for a technically meaningful interval of 0.9 to 0.98. These interval limits refer to a maximum space of the order of a diameter of 170 ⁇ 20 mm, which is determined by the geometry of the rotor carrier 46.
- the second torsional damper 20 is limited by its small radial extent in its performance. However, this is clearly overcompensated by the use of the previously connected and powerful speed-adaptive damper 6, resulting in a very good decoupling quality of rotational irregularities.
- a rigidity ratio between the first and second torsional damper 10; 20 is from 1: 7 to 1:10. In this case, a ratio between the spring outside diameter of the first and second torsion damper 10; 20 about 1 ⁇ 0.3.
- a separation from the dry working space 24 to the moist working space 26 is effected by a in the first housing member 47 integrally with the first housing member 47 running partition 8, also referred to here as a bearing plate.
