Abstract:
A frictional coupling, comprised of: at least two coupling bodies (1,2), which come into frictional contact upon engagement of the frictional coupling, a first of the two coupling bodies having a ring-shaped base body (3) made of metal with at least one flat, conical or cylindrical carrier surface, a frictional layer made of organic or inorganic frictional material (4) is attached to said at least one carrier surface, and a second of the two coupling bodies having a counter body (8) made of metal, and having a counter surface which works together with the frictional layer, a wear material (10, 1415) made of paraffin or wax is applied between the base body (3) and the counter-body (8), onto at least one part of the surface (4, 9, 11', 3') facing the other coupling body (1,2), the wear material (10, 14, 15) keeps the base body (3) and the frictional layer from being in contact with the counter-body (8) and the wear material (10, 14, 15) closes the frictional coupling for a short time in a first operation during the frictional contact between the coupling bodies (1, 2) through frictional forces.
