Abstract

The invention relates to a braking device comprising a stator and a rotor. The rotor and the stator are positioned in relation to one another in such a way and a working medium can be supplied or connected in such a way that during a braking operation a braking moment is transferred from the rotor to the stator when the working medium is supplied or connected. The inventive braking device is characterised by the following: a fan impeller, which can enter into and be disconnected from a drive connection with the rotor by the activation and deactivation of a coupling; the fan impeller is configured and positioned in such a way that it supplies a stream of cooling air to the braking device, when the drive connection with the rotor has been made; the coupling is positioned and supplied with working medium in such a way that the supply or connection and evacuation or disconnection of the working medium automatically activates and deactivates the coupling.
