  • Sintered friction material
    Patent number: 11534829
    Abstract: A sintered friction material is formed by pressure sintering mixed powder at 800° C. or above, the mixed powder consisting of, in mass %, Cu and/or Cu alloy: 40.0 to 80.0%, Ni: 0% or more and less than 5.0%, Sn: 0 to 10.0%, Zn: 0 to 10.0%, VC: 0.5 to 5.0%, Fe and/or Fe alloy: 2.0 to 40.0%, lubricant: 5.0 to 30.0%, metal oxide and/or metal nitride: 1.5 to 30.0%, and the balance being impurity.
    Type: Grant
    Filed: April 7, 2017
    Date of Patent: December 27, 2022
    Assignees: NIPPON STEEL CORPORATION, FINE SINTER CO., LTD.

  • Brake lining for a railway vehicle and disk brake equipped with the same
    Patent number: 11434964
    Abstract: This brake lining includes: a plurality of friction members which are arranged to be spaced from each other, each of the friction members having a front surface that is to face a sliding surface of a brake disk; a back board fastened to a back surface of each of the friction members; a base plate that supports each of the friction members at a region including a center portion of each friction member; and an elastic member disposed between the base plate and the back board, on a back surface side of each friction member. Two friction members that are adjacent to each other are taken as a pair, and the back board is fastened to each of the pairs of friction members. In each pair of friction members, the two friction members are arranged along the circumferential direction of the brake disk.
