Fluid coupling

This diploma´s thesis deals in the first part with hydrodynamic coupling, mainly on her construction and function description. In the second part of this diploma´s thesis is solved influence construction changes of the hydrodynamic coupling to the transmitted torque. Changes in the construction are determined by changing the number of blades and changing the value gap between the turbine and pump round. Finally, construction change is solved of the hydrodynamic coupling to increase the transmitted torque and force effects are evaluated on the hydrodynamic coupling
