Abstract

This invention relates to a controllable clutch based on electrorheological or magnetorheological liquids, in which the transmission of force or the transmission of torque is achieved in that an electrorheological or magnetorheological liquid is pushed through an electrode gap or magnet gap of the clutch by means of a surface acting as a piston.
