Abstract
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.
