Abstract

A freewheel device having a switchable freewheel which may include a first race, a second race, locking elements arranged between the first and second races and a locking element cage for receiving the locking elements. The locking element cage may be rotated relative to the first race to a first rotational position in which the first race is in rotationally entraining connection to the second race via the locking elements and to a second rotational position in which the first race is not in rotationally entraining connection to the second race. The switching device may be formed by a first planetary gear, a second planetary gear and a switching drive.
