Definitions

  • the invention relates to a method for producing a brake disk according to the preamble of claim 1, as well as a brake disk according to the preamble of claim 5.
  • a brake disk pot and a friction ring is often shown separately from different materials and then assembled to the brake disc.
  • EP 1 476 670 Bl it is provided to form a brake disk pot by means of an internal high-pressure method onto a friction ring, wherein the friction ring has inwardly directed truncated pyramids around which the brake disk cup is formed.
  • the invention is based on the object to make a connection between a brake disk hub and a friction ring, which has a relation to the prior art, higher mechanical strength and is inexpensive to produce.
  • the solution of the problem consists in a method for producing a brake disc having the features of claim 1 and in a brake disc having the features of claim 5.
  • the method for producing a brake disk according to claim 1 is that a brake disk pot and a friction ring are joined together by a forming process. In this case, material is pressed radially outward by the forming process from the side of the brake disk pot and formed in also radially outwardly extending recesses in the friction ring.
  • the molded material may be material from the brake disk pot itself or may be introduced by additional fasteners such as rivets formed through openings in the brake disk pot.
  • Another component of the invention is a brake disc having the features of claim 5.
  • Fig. 4 shows another composite brake disc
  • FIG. 5 shows a detail of the brake disk from FIG. 4.
  • a brake disk chamber 4 is shown, which is formed for example of an aluminum alloy and is produced in a die-casting process.
  • a friction ring 6 in Fig. 3 is made of a cast iron alloy and is represented by an iron casting method.
  • FIG. 2 shows a cross section through a brake disk, the brake disk chamber 4 being joined to the friction ring.
  • the joining takes place by means of a hydroforming process, wherein the friction ring 6 and the brake disk chamber 4 are inserted into a tool such that the mutual position substantially corresponds to the brake disk.
  • high pressure which is applied for example hydrostatically, pins 22 which are already present in the brake disk chamber are pressed radially outward, so that they are formed into recesses 8 in the form of blind holes 18 in the friction ring 6.
  • the originally short pins 22 are thus deformed longitudinally by the high pressure, which is usually accompanied by a rejuvenation of the wall thickness.
  • the pins 22 sit after forming positively in the recesses 8 and secure the brake disc hub 4 opposite the friction ring 6 in the axial direction 24 and in the tangential direction 28th
  • the recesses 8 may also be configured in the form of axially-shaped grooves 20, as shown in Fig. 4. In this case, an additional axial securing, for example in the form of a retaining ring is appropriate.
  • a further embodiment of a brake disc 2 is shown.
  • This brake disc 2 is designed with an internal ventilation, which manifests itself by two friction plates 30 separated by webs 28, which together form the friction ring 6.
  • a brake disk pot 4 is also connected to the friction ring 6 by a forming process.
  • the brake disk 4 from FIG. 5 differs from the preceding example in that it is not the material of the brake disk cup 4, namely the pins 22, that are pressed into recesses 8.
  • an additional material in the form of connecting elements 10 is used, which in turn are configured in the form of rivets 32 in this embodiment.
  • the rivets 32 are pressed through openings 12 in the brake disk chamber 4 in the radial direction 26 extending recesses 10 of the friction ring.
  • a hydroforming process is used to press in the rivets.
  • a drawing punch can also be used for both embodiments, which presses the pins 22 or the rivets 32 into the depressions 8 provided for this purpose.
  • the depressions 10 in the friction ring 6 according to FIG. 5 have undercuts 34, which can be seen in the enlarged sectional view of FIG.
  • the rivets which can be configured as solid rivets or rivets
  • the recess 10th expanded and pressed into the undercuts 34, which further increases the strength of the connection.
  • the recesses 10 are preferably arranged centrally in the axial direction 24, whereby a shielding of the brake disc is minimized.
  • Shielding means an umbrella-shaped curvature of the friction ring 4, which is caused by a different thermal expansion of the brake disk hub and the friction ring 6.
  • a central arrangement should be understood to mean an offset of 10% from the axial center in both axial directions.
  • an insulation layer for example in the form of an iron foil, for thermal insulation between friction ring 6 and brake disk chamber 4.
  • zinc dust can be introduced into the recesses and / or at the contact surfaces, which leads to the avoidance of contact corrosion.

Abstract

L'invention concerne un procédé de fabrication d'un disque de frein (2) par l'assemblage d'une cloche de disque de frein (4) et d'un anneau de friction (6) au cours d'un processus de formage. L'invention est caractérisée en ce que le processus de formage du côté de la cloche de disque de frein (4) permet de former de la matière dans des creux (8) de l'anneau de friction (6) agencés radialement vers l'extérieur.
