  • Patent number: 11536329
    Abstract: A brake pad for a disk brake of a vehicle, in particular a rail vehicle, includes a backing plate, to which a plurality of friction units is fastened, each using a securing element supported on the rear side of the backing plate facing away from the friction unit, wherein each friction unit has, on the side of the backing plate facing away from the securing element, a friction element, which is mounted for tilting by means of a spherical-portion-shaped attachment and under the load of a spring supported on the backing plate, is designed in such a way that an annular disk is arranged between the spring and the friction element, at least some regions of said disk lying against the spring and the friction element.

  • Patent number: 10816050
    Abstract: A brake lining for a disc brake includes a distribution of lining elements which are arranged on a lining support or on group supports in groups, and the group supports are secured to the lining support. The lining elements have first lining elements and second lining elements, and the group supports have a first group support and a second group support. The first lining elements are arranged on the first group support or on the lining support in a non-tiltable and/or inflexible manner, and the second lining elements are arranged on the second group support or on the lining in a tiltable and/or flexible manner.

  • Patent number: 10718392
    Abstract: An arrangement for a brake lining, method for actuating the brake lining and the brake lining itself are a partially lined disc brake of a rail vehicle that has a lining support and multiple group elements arranged on the lining support. Each of the group elements consists of a support plate and multiple lining elements arranged on the support plate, and lining elements with at least two friction surfaces of differing sizes are arranged on each support plate. The lining elements are arranged such that their total surface area at least approximates a ring sector, and at least two different first and second group elements are arranged on the lining support.

  • Publication number: 20180355931
    Abstract: A brake pad mounting of a brake pad of a disc brake of a rail vehicle on a pad holder of the disc brake is described, wherein the pad holder has a holder plate and at least one locking element for securing the pad carrier on the holder plate, the brake pad has a pad carrier plate and at least one pad element arranged thereon, in the mounted position of the brake pad on the pad holder the pad carrier plate is held on the pad holder in a form-fitting manner, wherein border-side embracing webs which extend in the direction of the pad carrier plate and have grooves open with respect to the surface centre of the holder plate are integrally formed on the holder plate. A brake pad and a pad holder are furthermore described.

  • Publication number: 20180017123
    Abstract: A brake lining for a partial-lining disk brake of a rail vehicle includes a lining carrier and a plurality of lining elements mounted on the lining carrier via carrier plates spherically, wherein the mounting of the lining elements on the lining carrier via the carrier plates are designed such that a surface pressure of the lining elements generated by a brake application force during pressing of the lining elements against a brake disk decreases radially relative to the axis of rotation of the brake disk with increasing distance of the lining elements from the axis of rotation of the brake disk.
