Abstract
A frictional shift element for a transmission of a vehicle, including a first friction element and a second friction element, wherein one friction element of the first and second friction elements has an approximately annular friction surface, and the other friction element of the first and second friction elements has an approximately annular base body and a plurality of friction surface elements distributed over a periphery of the approximately annular base body. The friction surface and the plurality of friction surface elements are brought into contact with each other in an overlap area for transmitting torque, wherein the friction surface elements protrude radially into the overlap area. The one friction element with the friction surface, the other friction element, and the friction surface elements are each formed as one piece. The one friction element and the approximately annular base body of the other friction element are spaced radially apart.
