Steering device with a magnetorheological braking device and method for operating a steering device

A steering device for steering a vehicle by, comprising:

• a movable steering unit;
• at least one magnetorheological braking device configured to brake a movement of said steering unit;
• said braking device having a stationary holder and at least two brake components, at least one of said at least two brake components is rotatable by said steering unit and at least one other of said at least two brake components is non-rotatably connected to said holder;
• said at least two brake components being continuously rotatable relative to one another about an axis of rotation;
• a first brake component of said at least two brake components extending along said axis of rotation and having a core made of a magnetically conductive material, and a second brake component of said at least two brake components having a hollow casing part extending around said first brake component;
• at least one circumferential gap formed between said first brake component and said second brake component, said at least one circumferential gap being filled at least partially with a magnetorheological medium;
• and
• said gap having at least a first braking gap section and a second braking gap section, said first braking gap section having a disk contour formed between said casing part and said core, and said second braking gap section having a plurality of rolling elements arranged on a circumference of said core.
