Friction plate having a groove pattern formed by means of friction lining pads

A groove pattern for an annular wet friction system having external lubrication, comprising a frictional surface having a circumferential groove extending circumferentially in a zigzag or undulating manner, wherein:

• the circumferential groove is arranged, in a radial direction, between first pentagonal friction lining pads arranged radially outwards in a first row of pads and second pentagonal friction lining pads arranged radially inwards in a second row of pads;
• the first and second pentagonal friction lining pads have a rectangular geometry with an immediately adjacent triangular geometry;
• tips of the triangular geometry of the first pentagonal friction lining pads are directed radially inwards and tips of the triangular geometry of the second pentagonal friction lining pads are directed radially outwards;
• first radial grooves are arranged in a circumferential direction between the first pentagonal friction lining pads and second radial grooves are arranged in the circumferential direction between the second pentagonal friction lining pads;
• the tips of the triangular geometry of the first pentagonal friction lining pads face the second radial grooves and the tips of the triangular geometry of the second pentagonal friction lining pads face the first radial grooves;
• the first pentagonal friction lining pads have a V-shaped double groove comprising two stamped grooves spaced apart in the circumferential direction with a distance therebetween decreasing radially outwards;
• an angle between the two stamped grooves is between twenty (20) degrees and thirty (30) degrees;
• and
• the two stamped grooves each extend uninterruptedly from an outer edge of the first pentagonal friction lining pad towards an outer edge of a respective second pentagonal friction lining pad and open into the circumferential groove.
