Abstract (en)
[origin: WO2021123343A1] A magnetorheological braking device (1) with a fixed holder (4) and with two braking components (2, 3), wherein one of the two braking components (2, 3) is connected fixedly to the holder (4) so as not to rotate relative thereto, and wherein the two braking components (2, 3) are continuously rotatable relative to one another, wherein a first braking component (2) extends in the axial direction (20), and wherein the second braking component (3) comprises a shell part (13) of hollow configuration which extends around the first braking component (2). A peripheral gap (5) which is filled with a magnetorheological medium (6) is configured between the first and the second braking component (2, 3). The first braking component (2) comprises an electric coil (26) and a core (21) which extends in the axial direction (20) and which is made from a magnetically conductive material, wherein the core (21) comprises a main body (33). Magnetic field concentrators (80, 81) which are configured on the core and/or magnetic field concentrators (80, 81) which are configured on the shell part protrude into the gap (5), which results in a peripheral gap (5) with a variable gap height (5b). The electric coil (26) is wound around at least one section of the core (21), with the result that a magnetic field (8) of the electric coil (26) runs through the core (21) and the magnetic field concentrators (80, 81) and through the gap (5) into a wall of the shell part (13).
