Patent ID: 8113330

Claim:
A friction disk for a wet-running clutch in a motor vehicle, the friction disk comprising: a lining carrier ring having opposed faces and connecting areas for connecting to one of a drive side and a takeoff side of a clutch; and a plurality of friction lining elements on at least one face of the carrier ring, circumferentially adjacent said friction lining elements on one side being separated by fluid flow channels, each said friction lining element have a friction surface, at least one of the friction lining elements having a groove arrangement in the friction surface the groove arrangement having a plurality of grooves, each of the plural grooves having a respective width, wherein the plural grooves do not intersect, wherein each plural friction lining element has a radially inner side, a radially outer side, a first circumferential side, and a second circumferential side, and the groove arrangement provides at least one first radially continuous groove connection from the radially inner side to the first circumferential side of the at least one friction lining element, wherein the groove arrangement provides at least one second radially continuous groove connection from the radially outer side to the second circumferential side of the at least one friction lining element, and wherein the at least one first radially continuous groove connection and the at least one second radially continuous groove connection on a respective friction lining element have opposite radial curvatures.
