Abstract
A friction disc has a flat carrier ring which includes a first surface and a second surface, wherein a first annular friction lining is arranged on the first surface, the first annular friction lining including a geometry that deviates from the circular ring shape, wherein the carrier ring also includes the geometry of the first friction lining, each as viewed in the axial direction, and/or the first annular friction lining including at least one opening in the axial direction, which extends in the axial direction also through the carrier ring, wherein the opening is formed to start at the inner circumference or at the outer circumference of the carrier ring.
Claims7
A friction disc having a flat carrier ring which comprises a first surface and a second surface,
- wherein a first annular friction lining is arranged on the first surface,
- wherein the first friction lining is a scatter-sintered friction lining sintered onto the carrier ring,
- wherein a first opening is formed in the first friction lining in an axial direction, which extends in the axial direction also through the carrier ring,
- wherein the first opening in at least some areas of the carrier ring and the first annular friction lining has a dome-shape starting at an outer circumference of the carrier ring and becoming smaller inwardly in the radial direction;
- wherein if the friction disc is an inner disc, the friction disc comprises at least one driver element on a radially inner end face, which is separate from the first opening;
- and
- wherein if the friction disc is an outer disc, the friction disc does not have at least one driver element on the radially inner end face.
