Abstract
Magnetorheological transmission device and method for influencing the coupling intensity of two components, which can be coupled and whose coupling intensity can be influenced. A channel is provided, which contains a magnetorheological medium with magnetically polarizable particles, which can be influenced by a magnetic field. A magnetic field generating unit generates a magnetic field in the channel in order to influence the magnetorheological medium in the channel. A body is disposed in the channel. A free distance between the body and the component is at least ten times greater than a typical mean diameter of the magnetically polarizable particles in the magnetorheological medium. A space with magnetorheological medium is disposed between the body and a component. The magnetic field is applied to the region in order to optionally chain together the particles and/or wedge or release them with the body.
