MAGNETORHEOLOGICAL TRANSMISSION APPARATUS

摘要

Transmission apparatus comprising at least two couplable components, which move in translatory fashion in relation to one another, wherein a coupling gap extends between a first and a second end between the components. The coupling gap is provided with a magnetorheological medium. A magnetic field generation device for generating at least one magnetic field in at least part of the coupling gap is provided in order to influence coupling between the couplable components. The coupling gap is configured and sealed off from the outside in the translatory direction at the first end and at the second end in such a way that the magnetorheological medium remains in the coupling gap as a type of controllable friction lining independently of a coupling between the couplable components in order to influence the coupling via shear forces between the couplable components corresponding to the magnetic field present in the coupling gap. A plurality of radially extending arms on one of the components is provided, which arms are each equipped with a magnetic field generation device. Each magnetic field generation device comprises an electrical coil having at least one winding. The winding extends in each case completely next to the central axis and spaced apart from the central axis. Different poles of the magnetic field generation devices are provided at the adjacent ends of adjacent arms of a component. The coupling gap is connected to a reservoir for magnetorheological medium.
