Abstract
A frictional part for a frictionally operating device includes friction lining pieces, which are spaced apart from one another to form an annular disc-like friction surface having grooves, and the friction lining pieces have the shape of triangles and pentagons. The pentagonal friction lining pieces may be provided with a radially inward or outward directed top and may be intrinsically symmetrical with respect to a radial. The pentagonal friction lining pieces may be oriented with the tops thereof alternating radially inward and radially outward. The triangular friction lining pieces may have the shape of acute-angled or right-angled triangles having one short and two longer sides. The triangular friction lining pieces may each have a longest side which is arranged radially inward or radially outward. The pentagonal friction lining pieces may each be arranged in the circumferential direction between four triangular friction lining pieces.
