  • Patent number: 7143882
    Abstract: Disk (1, 11) for a force transmitting aggregate, in particular for wet disk clutch, with a core plate (2, 12) exhibiting a front side (V) and a backside (R), wherein the front side (V) and/or the backside (R) exhibits a friction lining (3v, 3r, 13v) which may be provided with grooves (4a, 4b, 5a, 5b, 5c, 14a, 14b, 15a, 15b, 15c). In accordance with the invention, in the case of a friction lining with an essentially planar surface (O3v, O3r, O13v) at least one surface area (6) is provided which is raised in comparison to this planar surface (O3v, O3r, O13v) and exhibits a spring characteristic. Alternatively thereto, it is envisioned in accordance with the invention that the cross-sectional area of the lining increases or decreases in the radial direction.
