Definitions

  • the invention relates to a brake lining for a partially lined disc brake according to the preamble of claim 1.
  • brake pads are used, the friction elements are made of a hard material.
  • the friction elements in the contact area with the carrier plate are provided with spherical-segment-shaped formations which engage in dome-shaped receptacles adapted thereto.
  • the support plate forms together with the friction elements positioned thereon a covering element, of which in turn several are held tiltably in a lining carrier.
  • the friction elements are displaced almost without any change in the contact pressure, which is essentially the same in all friction elements.
  • a homogeneous contact pattern is generated and local heat spots on the brake disc are avoided.
  • the Isobar brake pad Due to its high performance, the Isobar brake pad is primarily used in high-speed traffic, although when decelerating it causes a very high level of heating of the entire brake pad.
  • the heating capability of the system is limited by the achievement of the local deformation resistance of the carrier plate and the lining carrier, wherein the frictional heat is conducted via the contact friction element / carrier plate and the contact area carrier plate / lining carrier in the lining carrier.
  • the invention has for its object to develop a brake pad of the generic type so that its usefulness improved with little design and manufacturing effort and its life is increased. This object is achieved by a brake pad with the features of claim 1.
  • the dimensioning and shaping of the recess is in principle freely selectable and is limited only by the technically feasible.
  • a preferred embodiment of the recess is such that it is designed in the sense of a ball pan, quasi parallel to the spherical segment-shaped projection, with which the carrier plate rests tiltably in an adapted receptacle of the lining carrier.
  • the recess may also be polygonal in plan, with a flat or concave or convex curved bottom.
  • the recess as the support plate may otherwise be provided with a metallic coating or coated with a corrosion protection.
  • the friction elements can be facing surface of the support plate, at least in the areas not covered by the friction elements, be provided with a corresponding layer.
  • the recess can be designed such that it meets the requirements for rigidity of the carrier plate in order to achieve a favorable total compliance of the lining system.
  • the invention is also characterized by the fact that it is basically cost-neutral to implement.
  • the carrier plate is produced as a precision casting part, so that the recess can be cast with. It is also conceivable to produce the recess without cutting or machining, the former, for example, when the support plate is made of sheet metal and is deformed by stamping, drawing or the like.
  • the higher heat radiation that results from the new brake pad results in a higher load capacity, so that the new brake pad is particularly suitable for use in high-speed trains. In this respect, the usability of the brake pad is improved.
  • the new brake pad also has a longer service life, which naturally reduces the operating costs to a quite remarkable extent, which includes not only the procurement and assembly costs, but also the downtime of the vehicle. Further advantageous embodiments of the invention are characterized in the subclaims.
  • Figure 1 shows a partial section of the brake pad in a perspective
  • Figure 2 is a plan view of a support plate
  • FIG. 3 shows a section through the carrier plate according to the line III-III in FIG.
  • FIG. 1 shows a partial section of a brake pad for a partially lined disc brake, in particular a rail vehicle, with a plurality of pad elements 2 connected to a pad carrier 1, of which only one is shown in FIG.
  • Each covering element 2 has a carrier plate 3 and friction elements 4 mounted on the rear side in receptacles 6 of the carrier plate 3, wherein the receptacle 6 as a calotte and the region of the friction element 4 inserted therein are formed in a spherical segment.
  • the receptacles 6 are arranged in three, mutually angled legs 7 of the support plate 3.
  • the support plate 3, which is shown in Figures 2 and 3 as a detail, is tiltably held on the lining carrier 1, to which the carrier plate 3 has a kugelab- cut-shaped projection 9 which rests in a ball socket 10 of the lining carrier 1.
  • at least one recess 5 which enlarges the surface of the carrier plate 3 and is concentric with the projection 9 and spherical in the present embodiment is provided in the carrier plate 3, which is designed as a casting, adjacent to the receivers 6, with a central, sack-hole-like bore 8.
  • the depression 5 and the bore 8 are introduced during casting and positioned in the overlap region of the projection 9.
  • the curvature of the recess 5 corresponds in its course substantially to the curvature of the projection 9.

Abstract

La présente invention concerne une garniture de frein destinée à un frein à disque à garniture partielle notamment d'un véhicule ferroviaire, comprenant plusieurs éléments de garniture (2) raccordés à un support de garniture (1) et présentant chacun une plaque de support (3) et des éléments de friction (4) fixés sur la plaque de support et insérés dans des logements (6) sur le côté arrière, chaque plaque de support (3) étant maintenue contre le support de garniture (1) pour pouvoir effectuer un mouvement de basculement. La garniture de frein selon l'invention est conçue de sorte que la plaque de support (3) présente, au voisinage des logements (6), au moins une cavité (5) qui augmente la taille de la surface de la plaque de support (3).
