  • Patent number: 6623581
    Abstract: In order to regenerate a brake lining, preferably for a railway vehicle, a friction lining is worked by machining, starting from its worn surface, and provided with a three-dimensional surface profile. The profiled surface is then coated with an agglutinant, and a fresh friction lining substance is pressed on. The worn surface is preferably worked by profile grinding or profile milling, such that a profiled surface structure is produced having a teeth-like, trapezoidal or meander-shaped profile that is vertical to the surface, wherein the profile depth of the surface structure lies in the region of approx. 1-30 mm, preferably 5-20 mm. The profile is preferably oriented in one direction, crosswise to the main strain of the friction lining during braking.

  • Patent number: 6478125
    Abstract: Several long friction bodies (31 . . . 37) each with several rivets (4) , are fixed to the anchor plate of a disk brake pad (1) for rail or utility vehicles. The peripheral profile of each friction body is configured in the shape of a stadium so that the two semi-circle-shaped ends are each connected by parallel sides. The fixing rivets (4) are arranged at a mutual distance in the direction of the greatest longitudinal extension of the corresponding friction body (L1 . . . . L7). The directions of all of the greatest longitudinal extensions are at an acute angle &agr; to the run-in direction (E). The angles incidence (&agr;) are different for the various friction bodies of the friction body arrangement but are never greater than 45°.
