Abstract:
A frictional shift element for a motor vehicle transmission includes a first frictional element allocated to a first carrier; and a second frictional element allocated to a second carrier. One of the first frictional element or the second frictional element has an annular frictional surface, and the other of the first frictional element or the second frictional element has a corresponding frictional surface with at least one frictional surface that protrudes along a radial direction in an overlapping area.
