Abstract
A frictional surface for an annular wet friction system with external lubrication includes a groove pattern with first pentagonal friction lining pads, second pentagonal frictional lining pads, and a groove. The first pentagonal friction lining pads are arranged radially outwards in a first row and the second pentagonal friction lining pads arranged radially inwards in a second row. The groove extends circumferentially between the first pentagonal friction lining pads and the second pentagonal friction lining pads in a zigzag or undulating manner. In an embodiment, each of the first pentagonal friction lining pads has a triangular geometry with a first tip directed radially inwards and each of the second pentagonal friction lining pads has a triangular geometry with a second tip directed radially outwards.
