Abstract
The invention relates to a wet-running multi-plate clutch () comprising a number of inner plates () and a number of outer plates (), and a first friction lining () is disposed on either side of every inner plate () respectively and a second friction lining () is disposed on either side of every outer plate () respectively, and the first friction linings () are located entirely underneath the second friction linings () in the radial direction so that the first friction linings () move into frictional contact with the outer plate main bodies () when the multi-plate clutch () is engaged and the second friction linings () move into frictional contact with the inner plate main bodies () when the multi-plate clutch () is engaged. The first friction linings () respectively have at least one first groove () with a groove depth of up to 100% of a friction lining thickness of the first friction linings () and the second friction linings () have no or respectively have at least one second groove () which has a smaller cross-sectional surface area, as viewed in the longitudinal extension of the second grooves (), than the first grooves () as viewed in the same direction.
