ABSTRACT:
A power transmission unit with at least one driving shaft that can be coupled to a driven machine includes a modular hydrodynamic coupling unit. The coupling unit includes at least two blade wheels, which together form at least one toroidal working chamber. The two blade wheels each can be connected non-rotatingly to a hub-like element, which can be connected non-rotatingly with one of the driving shaft or driven shaft. An intermediate hub is disposed between at least one blade wheel and a corresponding hub-like element. The intermediate hub is coupled non-rotatingly to the blade wheel and extends in the axial direction from the blade wheel at least to directly above an axial end wall of the housing of the coupling unit. The intermediate hub is removably securable to the coupling housing. The hub-like element forms at least one axial stop for the intermediate hub when it is mounted in the housing. Also when the intermediate hub is mounted in the housing, it is non-rotatingly connected to the hub-like element in a region of the end of the driving shaft.
