Abstract

A friction part for a frictionally operating device includes a friction lining carrier and a friction lining. The friction lining includes friction lining pieces arranged in two rows to form an annular friction surface. The friction surface has an inner edge, an outer edge, and a groove set. The groove set has a first stem groove between the inner edge and a first branching point, a first branch groove between the first branching point and a first connecting point, a second branch groove between the first branching point and a second connecting point, a third branch groove between a second branching point and the second connecting point, and a second stem groove between the second connecting point and the outer edge. The first stem groove, and first and second branch grooves form a y shape. The second stem groove, and second and third branch grooves form an inverted y shape.
