Claim Text:
1. A freewheel device, comprising: a switchable freewheel having 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, which locking element cage is rotated relative to the first race, and a switching device by means of which the locking element cage is rotated to a first rotational position relative to the first race in which the first race is in rotationally entraining connection to the second race via the locking elements in a first direction of rotation relative to the second race, and to a second rotational position relative to the first race in which the first race is not in rotationally entraining connection to the second race in the first direction of rotation relative to the second race, wherein the switching device comprises a first planetary gear having three first components, being a first sun gear, a first planet gear carrier with at least one planet gear which is in rotationally entraining engagement with the first sun gear, and a first ring gear or gear wheel which is in rotationally entraining engagement with the at least one planet gear of the first planet gear carrier, and a second planetary gear having three second components, being a second sun gear, a second planet gear carrier with at least one planet gear which is in rotationally entraining engagement with the second sun gear, and a second ring gear or gear wheel which is in rotationally entraining engagement with the at least one planet gear of the second planet gear carrier, wherein the first race is connected non-rotatably to one of the first components and the locking element cage to one of the second components, another of the first components is connected non-rotatably to another of the second components, and a switching drive is engaged with a further of the first components or with a further of the second components.
