ANNULAR FRICTION LINING FOR A DRY CLUTCH.

摘要

The liner (1) has radial internal and external edges (2, 3) and a friction face (5) in which first annular groove (6) is arranged. The first groove extends from the internal edge to the external edge. The friction face comprises a second annular groove (8) that cuts through the first groove. The grooves define studs (9). Ratio between a sum of a bottom surface and a side surface of the first and second grooves and sum of friction surfaces of the studs is between 0.5 and 1..
