  • Patent number: 9677621
    Abstract: 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).

  • Patent number: 9624983
    Abstract: The invention relates to a friction assembly (1) comprising a first component (5) and a second component (8) and a plurality of inner discs (2) and a plurality of outer discs (3), wherein the inner discs (2) are arranged on the first component (5) and the outer disc (3) are arranged on the second component (8) and the inner discs (2) and the outer discs (3) are arranged alternately in 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 which has an opening (29) with an inner diameter (14), and wherein the inner disc (2) and/or the outer disc (3) can be adjusted relative to one another to form a friction connection with the friction rings (11) in axial direction (4). The freely rotating friction rings (11) are guided in the region of the inner diameter (14) on the first component (5).
