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.

Multi-plate clutch

A friction plate for wet-running applications includes an annular main body having a first and a second surface. A friction lining having first oil grooves and second oil grooves is disposed on at least one of the first and the second surfaces. The first oil grooves extend from a radially inner end face of the friction lining in the direction towards a radially outer end face of the friction lining and terminate at a distance short of the radially outer end face, and the second oil grooves are disposed directly adjoining the first oil grooves in the radial direction and have a smaller maximum width in the circumferential direction than the first oil grooves. The first oil grooves are provided with a cross-sectional widening in the region of a radially outer end. The cross-sectional widenings of the first oil grooves are disposed at different radial heights.
