Abstract
A friction part for a frictionally operating device includes a friction lining carrier and a friction lining. The friction lining includes pentagonal friction lining pieces arranged on the friction lining carrier to form an annular friction surface. Each of the pentagonal friction lining pieces has a two-dimensional shape made up of a rectangle and an isosceles triangle, and a base coinciding with a relatively long side of the rectangle. A radially inner row includes pentagonal friction lining pieces with a same first shape, a same first size, and a same first tip directed radially outward, and a radially outer row includes pentagonal friction lining pieces with a same second shape, a same second size, and a same second tip directed radially inward. The annular friction surface has an inner edge, an outer edge, and a groove set formed between the pentagonal friction lining pieces.
