- a torque transmission device having a primary side and a secondary side, which are rotatable relative to one another against the force of an energy accumulator, wherein the primary side and the secondary side are coupled together by a friction damper whose damping own shafts are controllable during operation ,
- the friction damper is preferably a viscous damper or includes a controllable viscous damper in addition to a dry friction damper.
- the viscous friction damper preferably comprises an electrorheological medium.
- the viscous damping can be controlled or regulated.
- Theological properties of a medium such as a liquid, are understood to mean its deformation and flow behavior.
- Electrorheological fluids have the ability to change their theological properties under the influence of mostly an electrical or even a magnetic field. In this case, the apparent viscosity of the electrorheological fluid increases with increasing field strength. This effect sets itself up with a high dynamic and in a short response time. The viscosity of the electrorheological fluid can therefore be controlled very quickly and with a large dynamic range by means of an electrical control signal and a corresponding conversion of the control signal into an electric field.
- Electrorheological fluids usually consist of a suspension
- polarizable particles and a non-conductive carrier liquid The size of the particles of relevant liquids is 1 to 15 ⁇ and their volume fraction 30 to 50%.

- the energy store comprises at least one spring which connects the primary side and the secondary side with one another, wherein the
- electrorheological medium at least partially surrounds the spring and thereby acts as a friction damper, in particular a viscous friction damper.
- electrorheological medium replaces or supplements the grease for lubrication of the spring, which is in particular a bow spring or an array of coaxial bow springs.
- the variable viscosity of the lubricant causes additional viscous friction between the coaxial bow springs and between the (outer) bow springs and the primary side and the secondary side.
- the friction damper comprises a damper bearing coupled to the primary side and a sliding flange coupled to the secondary side, each of which comprises surfaces which are displaceable and / or rotatable relative to one another by a gap, the gap being at least partially with the electrorheological medium is filled.
- the gap is preferably formed as a circumferential groove.
- the damper bearing and the sliding flange are each independent parts of the primary or secondary side and can therefore be optimized in terms of their geometry and arrangement for their intended use as damper elements.

- the friction damper in one embodiment of the invention comprises a roller bearing arranged between the primary side and the secondary side, wherein the
- electrorheological medium is added at least in parts of the rolling bearing and acts as a viscous friction damper.
- the rolling bearing between a primary side and secondary side is thus used in addition to the introduction of viscous damping in the system. This has the advantage that no additional component, apart from the electrical control of the electrorheological medium, is provided with additionally required space. This variant therefore requires only minimal additional space.
- the torque transmission device in one embodiment of the invention comprises means for generating an electric and / or magnetic field, wherein the field penetrates at least parts of the electrorheological medium of the friction damper.
- the means are in particular plates (capacitor plates) for generating an electric field or coils for generating a magnetic field or combinations thereof.
- the electrical energy for generating the respective field can be transmitted via wires and sliding contacts or in particular contactless, for example via magnetic transmission means to the rotating assemblies.
- a drive train of a motor vehicle comprising a torque transmission device according to the invention and by a method for operating such a drive train in the case of Controlling the electrical input signal of the transmitter, the damping properties, in particular a viscous damping, the friction damper is controlled due to a measured and / or simulated operating state of the drive train.
- the damper according to the invention is an electrorheologically operating medium which can change its viscosity appreciably by applying electrical or magnetic signals. Due to the electrorheological medium, components in the damper can be coupled or decoupled or their transmission behavior can be significantly influenced. Thus, for example, a coupling / decoupling of masses (primary and secondary mass) or friction elements (friction control disk) can take place or, for example, spring-type accumulators can be changed with regard to their spring rigidity. For this purpose, it may be provided that the damper fat has electrorheological properties. Alternatively it can be provided that the electrorheological medium is independent of the damper fat.
- the electrorheological medium operates in annular spaces with close spacings ( ⁇ 10 mm) to the component to be influenced, wherein the component to be influenced can be a largely annular flange.
- the lubricant of the damper bearing has this electrorheological properties.
- the transmission of information and control signals to the damper system is preferably via a radio link.
- energy can also be transmitted via this route to the rotating component.
