Abstract
A haptic operating device having a magnetorheological braking device, a stationary holder, and two brake components. One of the brake components is connected to the holder for fixed rotation therewith. The brake components can be continuously rotated relative to one another about a rotation axis. A first brake component extends along the rotation axis and has a magnetically conductive core. The second brake component has a hollow casing part extending around the first brake component. Axially spaced apart peripheral braking gap portions formed between the first and second brake components are at least partially filled with a magnetorheological medium. At least one third braking gap portion is located axially between a first and a second braking gap portion. A first electric coil is assigned to the first braking gap portion and a separately controllable second electric coil is assigned to the second braking gap portion.
