ABSTRACT:
The invention relates to a fluid-friction coupling for the cooling fan of an internal combustion engine. The torque transmission of the coupling is controlled in dependence upon the working temperature of the internal combustion engine. In order to suppress undesiredly high temperatures within the coupling at excessively high drive-input rotation speed, the torque transmission and thus the power loss are reduced when the working temperature of the coupling rises.
