Abstract: A freewheel has a first ring which has a first blocking contour on a first axial side and a second ring which is rotatable relative to the first ring and which has a second blocking contour on a second axial side pointing toward the first axial side of the first ring. Tiltable blocking bodies can be caused to engage into the first blocking contour and into the second blocking contour. A switching element tilts the blocking bodies. A displacement unit axially displaces the second blocking contour relative to the first ring between an active setting, which is axially approximated to the first ring, and an inactive setting, which is axially remote from the first ring and in which torque-transmitting blocking of the first ring with the second ring is prevented in any setting of the blocking bodies.
