Method for producing a pattern of depressions in the friction surface of a friction component and a friction component for a frictionally operating device having such a pattern of depressions

摘要

A method for producing a pattern of depressions in the friction surface of a friction component for a frictionally operating device, preferably a multiplate clutch or multiplate brake. After the preparation of the friction component, the pattern of depressions is produced by nontraditional material removal, removal of material preferably being accomplished in a contactless manner, particularly preferably with the aid of a laser beam.

1. A method for producing a pattern of depressions, in a friction surface of a friction component for a frictionally operating device, comprising: producing a friction component having a friction surface, and creating a pattern of depressions by removing material from the friction component; wherein the removing material comprises directing a laser beam at a friction material, in which the focal point of the laser beam and the friction component perform a movement relative to one another, by means of which the focal point of the laser beam is guided over the friction surface along at least one path or wherein the focal point is guided over the friction surface along a path which deviates from a straight line, or is an arcuate, curved or spiral path; and wherein the focal point is guided along at least two paths which intersect at an intersection point, wherein one of the paths end at the intersection point and the focal point is guided with a constant power of the laser beam, at least in the path sections adjoining the intersection point wherein the laser beam, with the constant power in the path sections adjoining the intersection point and a friction facing are matched to one another in such a way that the friction facing is completely removed at the intersection point but only partially removed in the path sections adjoining the intersection point.
