Abstract
An input device, such as a joystick, has an operating device, a magnetorheological brake device, and a controller for activating the brake device. An operating lever is disposed on a supporting structure for pivoting around at least one pivot axis. The brake device is coupled with the pivot axis for controlled damping of a pivoting motion of the operating lever. The brake device has a rotary damper with two components, namely, an inside component and an outside component. The outside component radially surrounds the inside component and a damping gap is formed in between that is filled with a magnetorheological medium. The damping gap can be exposed to a magnetic field to damp a pivoting motion between the two contrapivoting components about an axis. One of the components has radial arms equipped with an electric coil whose winding extends adjacent to and spaced apart from the axis.
