Abstract
A friction part for a frictionally working device includes a plurality of friction lining elements arranged to form a circular disk-shaped friction surface having radial slots disposed between the friction lining elements. The radial slots are arranged to receive a coolant or lubricant traversing from a radial inside of the friction surface to a radial outside of the friction surface. The conformation of the friction lining elements and the arrangement of the friction lining elements relative to one another are optimized with regard to an interdependency between a drawing-in of air and a separation behavior of the frictionally working device, and drag losses. The radial slots may extend in a diffuser-like manner from the radial inside to the radial outside, or the radial slots may narrow in a nozzle-like manner from the radial inside to the radial outside.
