Patent number: 9677621Abstract: The invention relates to an friction assembly (1) comprising a plurality of inner discs (2) and a plurality of outer discs (3), the inner discs (2) and the outer discs (3) being arranged alternately in an axial direction (4), and wherein between the inner discs (2) and the outer discs (3) respectively at least one freely rotational friction ring (11) is arranged, and wherein the inner discs (2) and/or the outer discs (3) can be adjusted relative to one another in axial direction (4) to form a frictional connection with the friction rings (11). The friction rings (11) are made from at least one resin, containing at least one additive, or a sintered material, wherein the friction rings (11) on a surface (19) facing an inner disc (2) and on a surface (18) facing an outer disc (3) comprise respectively at least one compacted area (20) and at least one non-compacted area (21) and/or at least one area (21) that is less compacted than the compacted area (20).Type: GrantFiled: August 20, 2015Date of Patent: June 13, 2017Assignee: Miba Frictec GmbHInventors: Falk Nickel, Andreas Promberger
