Patent ID: 8167107

Claim:
A wet clutch comprising: a first friction surface; a supporting part; and a ring-shaped friction lining having a surface on the supporting part, the ring-shaped friction lining having a flat ring-shaped second friction surface, having an inner and an outer circumference and having a thickness defined by a distance between the second friction surface and the surface on the supporting part, the friction lining having a defined porosity and having a porous structure permitting oil to flow through the porous structure from the outer circumference to the inner circumference when the flat second friction surface contacts the first friction surface, wherein the friction lining has at least one cut-out reducing an extent of the friction lining between the inner and outer circumference and extending through the entire thickness of the friction lining, wherein the at least one cut-out is on the outer and/or inner circumference of the friction lining, wherein the at least one cut-out includes a first cut-out situated on the outer circumference of the friction lining and another cut-out situated on the inner circumference of the friction lining, the cut-outs being situated opposite each other.
