    Abstract: A multidifferential device of the type comprising a plurality of differentials, whereby each comprises a differential holder with at least two epicyclic gears and two planetary gears and in which the imaginary rotation axis of all the differential holders and planetary gears is the same. The differential holders and planetary gears are designed as rotary members, whereof two serve as input members and one serves as the output member. They comprise two end members and, between them, a plurality of intermediate members in which an end input and output member is constituted as a planetary gear, whereby the epicyclic gears of every other intermediate differential holder member are located at the same radial level relative to said rotation axis. A plurality of intermediate differential holder members each comprises an external or internal planetary gear path on both of its faces. At least one inner or outer epicyclic gear of each end member comprises a planetary gear.
