Abstract: A magnetorheological braking device with a fixed holder and a first and second braking component. One of the braking components is connected to the holder and does not rotate relative thereto. The two braking components are continuously rotatable relative to one another. The first braking component extends axially, and the second braking component has a hollow shell part extending around the first braking component. A peripheral gap, filled with a magnetorheological medium, is formed between the first and second braking component. The first braking component has an electric coil and a magnetically conductive core extending axially. Magnetic field concentrators, on the core and/or the shell part, protrude into the gap, creating variable gap height. The electric coil is wound around a section of the core. A magnetic field of the electric coil runs through the core, magnetic field concentrators, and the gap into a wall of the shell part.

Abstract: A method and an assembly for pivoting a movable component having a drive device with an electric drive motor in order to influence a pivoting of the component between a first setting and a second setting. A position sensor detects a position measure for a setting of the component and a speed parameter for a displacement speed of the component. During a displacement of the component with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. The setpoint voltage is increased if a current intensity flowing through the drive motor is lower than the electrical setpoint current intensity, and the setpoint voltage is reduced if the current intensity flowing through the drive motor is higher than the electrical setpoint current intensity.
