SWITCHABLE MAGNETORHEOLOGICAL TORQUE OR FORCE TRANSMISSION DEVICE, THE USE THEREOF, AND MAGNETORHEOLOGICAL TORQUE OR FORCE TRANSMISSION METHOD

摘要

The present invention relates to a magnetorheological torque transmission device comprising two device parts separated by at least one transmission gap for transmitting torque, said gap being fillable and/or filled with a magnetorheological material, rotating relative to each other about an axis of rotation, wherein the magnetic circuit system of the torque transmission device comprises at least one permanent magnet having variable magnetization in addition to at least one electromagnet for generating the magnetic flux in at least one part of the transmission gap, wherein the electromagnet and the permanent magnet are designed and disposed such that the magnetization of the permanent magnet can be adjusted by changing the coil current of the electromagnet. The present invention further relates to a correspondingly designed force transmission device.
