HAPTIC CONTROL DEVICE WITH A MAGNETORHEOLOGICAL BRAKING DEVICE

A haptic operating device having a magnetorheological braking device, a fixed holder, and two braking components. One braking component is non-rotatably connected to the fixed holder. Both braking components are continuously rotatable relative to one another about a rotation axis. A first braking component extends along a rotation axis and comprises a magnetically conductive core. The second braking component comprises a hollow casing part extending around the first braking component. At least one circumferential braking gap filled with a magnetorheological medium is between the first and second braking components. An electrical coil, surrounding the core and around the rotation axis, is between the casing part and the core. Two different radial braking gap portions and a disk contour are formed at a first braking gap portion between the casing part and the core, and a plurality of rolling bodies are arranged as magnetic field concentrators at the periphery of the core in a second braking gap portion.
