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.

Abstract: A door component has a controllable damping device containing a magnetorheological fluid as a working fluid. Two connection units can move relative to one another. One of the two connection units can be connected to a support structure and the other of the two connection units can be connected to a moveable door unit of a vehicle in order to damp a movement of the door unit between a closed position and an open position under control of a control device. The damping device has an electrically adjustable magnetorheological damping valve which is current-less in an adjusted state of the damping valve. A damping property of the damping device is continuously adjusted as needed via an electrical adjustment of the damping valve.

Abstract: A door component has a controllable damping device and contains a magnetorheological fluid. Two connection units are movable relative to one another. One of the two connection units is connected to a support structure and the other one to a pivotable door unit. The device damps a movement of the door unit between a closed position and an open position in a controlled manner by way of a control unit. The magnetorheological damping device has a piston unit and a cylinder unit surrounding the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit is equipped with a first one-way valve. The two chambers are connected together, via an external return channel equipped with at least one controllable magnetorheological damping valve, to form a one-way circuit. When the piston unit moves in and out, the magnetorheological fluid flows through the piston unit in the same flow direction.

Abstract: A haptic operating device for a motor vehicle has a base, a stationary central part connected thereto, a rotary knob which can be rotated about the stationary central part and which has a hollow design. A magnetorheological transmission device influences the rotational movement of the rotary knob in a controlled manner. The transmission device has two components which can be rotated relative to each other and one component of which is designed as a brake component that can be rotated relative to the base. The stationary central part is secured to the base by means of a support arm. The transmission device and the support arm are arranged adjacent each other and both are received radially within the rotary knob. The rotary knob is rotationally fixed to the rotatable brake component via a coupling device.

The subassembly has a dividing body or separating body and at least one flow channel formed on the dividing body and extending along it with at least one flow path to influence a flow of a magneto-rheological fluid along the flow channel of the dividing body. The dividing body includes a magnetic field generation device for generating a magnetic field and a field closing device. At least the magnetic field generation device and the field closing device are filled with at least one solidifying medium using a placeholder which can be removed to form the three-dimensionally predefined flow channels on the dividing body.

Abstract: Closed-loop control of an energy absorber acting as a damper between two parts that are movable relative to one another. A damping force of the energy absorber, or damper, can be adjusted by way of the change in the viscosity of a magnetorheological fluid (MRF), which change can be influenced by a magnetic field of a coil. According to the method it is possible to decelerate an impact or a movement with the lowest possible forces in order to minimize possible consequential damage/loading by way of setting as constant a deceleration as possible, as small a deceleration as possible, by way of using the entire available deceleration travel, and low or zero residual speed at the end of the deceleration travel independently of the moving mass or speed.

Abstract: Magnetorheological transmission device and method for influencing the coupling intensity of two components, which can be coupled and whose coupling intensity can be influenced. A channel is provided, which contains a magnetorheological medium with magnetically polarizable particles, which can be influenced by a magnetic field. A magnetic field generating unit generates a magnetic field in the channel in order to influence the magnetorheological medium in the channel. A body is disposed in the channel. A free distance between the body and the component is at least ten times greater than a typical mean diameter of the magnetically polarizable particles in the magnetorheological medium. A space with magnetorheological medium is disposed between the body and a component. The magnetic field is applied to the region in order to optionally chain together the particles and/or wedge or release them with the body.

Abstract: A valve for a magnetorheological fluid is formed with a duct through which the magnetorheological fluid can flow and which can be exposed to a variable magnetic field such that the flow resistance of the duct can be set using the magnetic field in the duct. The magnetic field can be lastingly generated using a magnet device that is made at least in part of magnetically hard material. The magnetization of the magnet device can be lastingly modified by a magnetic pulse of a magnetic field generation device in order to lastingly change the magnetic field in the duct and thus the flow resistance of the duct. A valve of the invention requires energy only to change settings while a specific setting can be lastingly maintained without supplying energy.

Abstract: A valve device is formed with a through-channel and a field generating device. A fluid which can be influenced by a field is provided in the through-channel and the field generating device is configured to act on the field-influenced fluid in the through-channel by way of a field. At least one adjustment device is provided with which the field that is active in the through-channel can be adjusted. A portion of the cross-sectional area of the through-channel can be adjusted, the portion being exposed to a field of a specific intensity so that the through-channel can also only partly be exposed to a field of a specific intensity. Thus, the through-channel, as seen in the direction of the flow, can be divided into regions of different flow resistance, whereby characteristic curves, which were previously attained only with difficulty, are easily obtained when using the valve device in a damper, for example.

Abstract: A shoe contains an adjustable space for the foot and several fluidically connected chambers. In order to adjust the space for the foot, the flowability of a magnetorheological fluid can be influenced by one or more devices that generate a magnetic field and thereby adjust the space for the foot resulting in a better fitting of the shoe. The novel system may also be implemented in orthoses (e.g., pronation correction) or in complete shoes with orthotics devices for correcting musculoskeletal abnormalities.

Abstract: A valve for magnetorheological fluids is formed with a control duct in which the magnetic field of a magnetic device, consisting of a permanent magnet and coil, acts on the fluid. The viscosity of the fluid is directly proportional to the magnetic field strength, with the result that the flow resistance of the valve can be varied via the coil current. The respective control duct is arranged in the end-face region of the coil and runs radially with respect to the center line of the valve, with the result that high flux densities can be achieved in the control duct. A permanent magnet is arranged in the inner space of the coil and, even under currentless operating conditions, can close the valve up to a certain blocking pressure.
