An electromagnetic clutch is provided which includes—a selector sleeve arranged in a rotationally fixed manner on a first shaft and is adapted to be shifted linearly along the first shaft between an engaged and a disengaged state, a coupling body which is aligned coaxially to the first shaft, a stator which has a coil which serves to shift an armature ring linearly along the first shaft, the armature ring being mounted radially in an axial guide separately from the first shaft and the coupling body, wherein a shifting of the armature ring by the coil is also accompanied by a shifting of the selector sleeve. A method of closing and opening an electromagnetic clutch is also included herein.

Electromagnetic clutch comprising a selector sleeve

An electromagnetic clutch is specified, includes a shifting sleeve which is arranged on a shaft for joint rotation therewith and is linearly displaceable along the shaft between a first engaged position, a second engaged position and a disengaged position located between the engaged positions, a first clutch body and a second clutch body, which are axially spaced apart from each other and are each aligned coaxially with the shaft, each clutch body having an internal toothing, and a stator having a first and a second energizable coil. The shifting sleeve has a first toothing for engaging the internal toothing of the first clutch body in the first engaged position and a second toothing for engaging the internal toothing of the second clutch body in the second engaged position. The clutch furthermore includes a locking device which prevents the shifting sleeve from moving beyond the disengaged position in the direction of the further engaged position when the shifting sleeve is displaced out of an engaged position in the direction of the disengaged position. A method of actuating the clutch is also specified.
