The set of planetary gears (1) incorporates a first(5) and second (7) set of single planetary gears. One planetary gear holder of the first set is connected to a hollow wheel of the second set. . A hollow wheel of the first set is connected to a planetary wheel holder of the second set. One planetary wheel holder of the first set acts as reaction element. One drive mechanism selectively operates three elements of the t two sets. a first one-way coupling is positioned between a gear housing (11) and one element of the second set. A coupling selectively connects the first one-way coupling and the sun wheel of the second set. |
