Abstract
A disk clutch or brake, with inner and outer disk carriers that respectively carry inner and outer disks. The inner and outer disks are arranged axially in alternation next to one another. At least one of the inner and outer disk carriers have radial openings through which coolant flows toward the disks. The inner and/or outer disk carrier have a toothed component, which is fixed to and at least partially axially and radially encompasses a basic component. The inner or outer disks are fixed toothed component to prevent relative rotation while allowing axial displacement. Radial openings are formed in the basic and toothed components to enable a flow of coolant.
