Abstract:
A modular hydrodynamic coupling unit for use in a power transmission unit connected to a driving machine, the coupling unit for the transfer of torque between a driving shaft and a driven shaft, the coupling unit comprising:a) a primary blade wheel and a secondary blade wheel which form together a toroidal working chamber;b) a hub element non-rotatingly connected to each of the blade wheels, the hub element non-rotatingly connectable to the driving shaft and the driven shaft and secured against axial displacement;c) a housing with two axial end walls which extend at least along a part of a radial dimension of the housing;d) an intermediate hub disposed between at least one of the blade wheels and the hub element, the intermediate hub being non-rotatingly coupled to at least one of the blade wheels, the intermediate hub extending from the blade wheels in the axial direction at least to a location above one of the axial end walls;e) means for removably securing the intermediate hub in the housing, the hub element forming at least one axial stop for the intermediate hub when the intermediate hub is mounted in the housing; andf) means for non-rotatingly connecting the mounted intermediate hub with the hub element in a region of an end of the driving shaft.
