A synchronised shift device for locked connection of at least two shafts(30, 32), which shafts have different rotation speeds at the start of a shift procedure. An arrangement of first annular drive body (36),synchronisation body (42) and first annular coupling element (44) bring about synchronisation of the shaft speed prior to coupling by a synchronisation sleeve (50). A further shaft (60), coaxially arranged, may be provided with a similar arrangement of annular drive body (62) and coupling element (66) for synchronised connection with one of the other shafts (32). |
