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: An operating system with an operating device and an interface device. The operating device has a receiving part and an operating element movably mounted on the receiving part relative to the receiving part for performing an input. A movement resistance for the movability of the operating element is set based on a relative position of the operating element by a controllable braking device and considers a stored assignment between relative positions and movement resistances. The assignment is adjustable via interface device. The interface device displays a coordinate system with default points for a setting range that can be positioned by an input means. The interface device creates a curve, which runs in accordance with the default points, and the interface device displays the curve on the user interface and determines the assignment based on the shape of the curve.

A magnetic-field generator forms a magnetic field to influence the medium in the closed chamber. The second brake component is axially slidable on the first brake component to change a volume of the closed chamber to compensate for temperature-related and/or leakage-related volume changes.

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.

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.
