Patent number: 11300990Abstract: 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.Type: GrantFiled: February 28, 2020Date of Patent: April 12, 2022Assignee: INVENTUS Engineering GmbHInventor: Stefan Battlogg

Patent number: 11287009Abstract: A rotary damper has a housing and a damper shaft rotatable in the housing. A damper volume contains magnetorheological fluid for influencing the damping of a damper shaft rotation relative to the housing. A partition wall on the shaft and a partition wall formed on the housing divide the damper volume into two variable chambers. A gap is formed between the partition unit of the housing and the damper shaft, and a gap is formed between the partition unit on the damper shaft and the housing. The magnetic field source includes a controllable electric coil for influencing the strength of the magnetic field and thus the strength of damping.
