  • Another permanent magnet 126 is by means of a stroke drive, for example one electromotive spindle drive 119 displaceable in the axial direction.
  • a stroke drive for example one electromotive spindle drive 119 displaceable in the axial direction.
  • the radial slide 122 by the repulsive forces of the permanent magnets 124, 126 in an opening of the lock bit 32 driven to form fit between the lock bit 32 and shaft 18 to manufacture.
  • the radial slide 122 is form-fitting in one Deepening of the shaft 18 is added, so that between the shaft 18 and the lock bit 32 no form fit is established.
  • the radial slide can be disengaged automatically, e.g. by means of roof-like Flanks between the radial slide 122 and the locking bit 32.
  • FIG. 11 shows an alternative embodiment of a slide 40 "'.
  • the slider is circumferential instead of several distributed first permanent magnet 42 and a plurality of circumferentially distributed second Permanent magnet 44 a disc-like permanent magnet 130 on this is in Aligned longitudinal direction of the axis 19 and acts regardless of the rotational position the north pole of the permanent magnet 130 for decoupling (or coupling) and the South Pole for coupling (or decoupling).
  • the slide 40 "' is structurally easier to manufacture, but it will not achieved magnetic reset as described above.
  • FIG. 12 shows a further alternative embodiment of a slide 40 IV .
  • the longitudinal groove 66 ′′ is in the region of the second permanent magnet 44 a little longer.
  • a stable uncoupling position of the slide 40 can also be achieved without self-locking of the lifting drive 36.
  • the stroke H of the slide 40 IV is selected such that, in the decoupling position, the permanent magnet 54 is offset by a travel amount ⁇ s with respect to the second permanent magnet 44.
  • the repelling poles are slightly further apart than if they were directly opposite each other.
  • a certain repulsive force must be overcome in order to move the slide 40 IV from the uncoupling position towards the coupling position.
