Abstract

A disk brake having an electromagnetic friction clutch that can be brought into controllable frictional engagement with a brake disk. The friction clutch can act on a device for generating hydraulic pressure independent of the direction of rotation, and this pressure can act upon a clamping device for operating friction linings. To press the friction linings against the brake disk, energy is taken from the rotating vehicle wheel by means of the friction clutch and metered to the clamping device with pressure fluid as the energy carrier. The friction brake can be used in passenger cars, for example.
