  • Sintered friction material for a friction lining
    Patent number: 10247271
    Abstract: A sintered friction material comprises a metallic matrix and granular constituents embedded in the matrix. The metallic matrix comprises a copper base alloy. The friction material is characterized in that the granular constituents comprise at least one sintered cemented carbide in a proportion of up to 9 weight percent, based on the total weight of the friction material. Furthermore, a friction body, in particular for clutches and brakes, that comprises a friction lining with at least one layer made of the sintered friction material, and a method for the production of a friction lining with the sintered friction material are described.
    Type: Grant
    Filed: June 16, 2017
    Date of Patent: April 2, 2019

  • Friction ring and method for producing same
    Patent number: 9718093
    Abstract: The invention relates to a friction ring, in particular for wet-running clutches or transmissions, having a carrier (10) and a friction lining (12) with a friction lining starting material (20) being a mixture at least of a thermosetting binder and a filler, and with the friction lining starting material (20) having a non-flowable, pasty processing consistency and the friction lining (12) having a solid final consistency after processing on the carrier (10). The invention further relates to a method producing such a friction ring.
