Magnetorheological braking device

A magnetorheological braking device, comprising:

• a brake housing, a stationary mount, and at least two brake components including a first brake component and a second brake component;
• one of said brake components being connected to said mount in a rotationally fixed relationship, and said at least two brake components being continuously rotatable relative to one another;
• said first brake component extending in an axial direction and having a core of a magnetically conductive material that extends in the axial direction;
• said second brake component including a hollow casing part which extends about said first brake component, forming an encircling gap;
• a magnetorheological medium at least partially filling said encircling gap;
• an electric coil disposed in said brake housing;
• a star contour disposed between said casing part and said core, said star contour having magnetic field concentrators that protrude into said gap to form therein an encircling gap section having a variable gap height in a region of said star contour, and said star contour including at least one stack of star sheets.
