Abstract
A magnetorheological braking device with a fixed mount and with two braking components. One of the two braking components is non-rotatably affixed to the mount and the two braking components are continuously rotatable relative to one another. A first braking component extends in the axial direction. The second braking component has a hollow shell part that extends around the first braking component. A peripheral gap is filled with a magnetorheological medium. The first braking component has an electric coil and a core made from a magnetically conductive material. Magnetic field concentrators on the core and/or magnetic field concentrators on the shell part protrude into the gap, which results in a peripheral gap with a variable gap height. A magnetic field of the electric coil runs through the core and the magnetic field concentrators and through the gap into a wall of the shell part.
