ABSTRACT:
A hysteresis coupling comprising a magnetic cylinder (1) made of a permanent-magnetic material and a thrust ring (4) made of a hysteresis material. The thrust ring (4) is fixedly connected to a thrust ring holder (5) and separated from the magnetic cylinder (1) by an air gap (3). The hysteresis coupling transmits the torque from a drive (7) to a pinion (9) which is part of the thrust ring holder (5). The thrust ring (4) is surrounded on its outside by non-magnetic material of high density in order to increase the moment of inertia (5) for noise reduction.
