Abstract
A shiftable disk clutch or disk brake having two clutch parts which are rotatable relative to one another about a theoretical axis of rotation. Each of the two clutch parts has at least one clutch disk which is stiff against rotation and is rigidly connected with the clutch part so as to be fixed against movement in every direction. A remotely actuatable pressure supply is divided into at least two separate pressure systems, each of which is, by itself, capable of coupling or separating the clutch disks.
