Abstract
A disk brake has an electromagnetic friction clutch that is brought into controllable frictional engagement with a brake disk. The friction clutch is in form-fitting rotational engagement with a piston of a clamping device for the friction linings associated with the brake disk, the piston is axially displaceable by a key driver that is independent of the direction of rotation. To press the friction linings against the brake disk, energy is provided by the rotating vehicle wheel by the friction clutch and metered to the clamping device. The friction brake can be used in passenger cars, for example.
