Definitions

  • the invention relates to a Bremsschetbe according to the preamble of the main claim.
  • Such a brake disc is known from DE-A-35 15 512.
  • the brake ring consists of a VoH ceramic disc, which is held in the brake disc carrier.
  • the brake disc is characterized by increased wear resistance due to the great hardness of the ceramic material.
  • a disadvantage of this brake disc lies in another ceramic property, the brittleness. Therefore, this brake disc is much more susceptible to breakage under impact and bending loads than, for example, brake discs made of metal. Weiber is disadvantageous in such a Bremsschedbe that the connection between the ceramic brake ring and the normally made of metal, brake disc carrier is difficult to make.
  • the object of the invention is therefore to design a generic brake disc in such a way that it is non-sensitive while maintaining a high wear resistance against impact and bending loads. In addition, it should be easy to manufacture.
  • the brake shoes In order to ensure that the brake shoes do not get caught between the ceramic plates during a braking process, they have such a shape and are spaced from one another such that they overlap at least partially in a radial orientation. In this way, the brake shoe of the disc brake always grinds on the next ceramic plate before it releases the previous one.
  • a diamond-like shape is chosen.
  • other forms which fulfill the above-mentioned purpose can also be used.
  • the brake disc can be manufactured in a simple manner.
  • the ceramic plates are ring-shaped around the carrier material of the brake ring, so that only the friction surfaces interacting with the brake shoes remain free. An additional attachment is not necessary, since the shrinkage stresses that occur when the carrier material cools hold the ceramic plates securely. In addition, the shrinkage of the carrier material leads to compressive stresses in the ceramic ik platelets, which make them even more unbreakable.
  • both the brake ring, insofar as it serves as a carrier for the ceramic plates, and the brake disc carrier consist of one piece from one material.
  • the material can be aluminum, but the choice of material is not limited to this.
  • all that is required is to insert the ceramic plates into a mold that forms the brake pad, which is then filled with the desired material. After the mold has cooled and separated, the finished brake chute is already available. Small purifications are necessary at most.
  • the brake disc according to the invention is characterized by a low weight, high temperature resistance, insensitivity to impact and bending stresses and by a low wear while driving.
  • Fig. 1 is a not entirely complete brake disc
  • FIG. 2 shows a section through the brake disc according to FIG. 1 along the section line II-II and on a somewhat enlarged scale
  • a brake disc for a vehicle disc brake is generally designated 1.
  • the brake shed 1 has a fastening section 2 serving as a brake disk carrier with a plurality of fastening eyes 2a distributed over the circumference.
  • the brake shed 1 can be screwed onto a vehicle wheel to be braked, not shown in more detail, via the fastening eyes 2a.
  • the actual brake ring 3 is integrally connected to the fastening section 2 radially outward. It provides diamond-shaped ceramic plates 4 distributed over its circumference, which are spaced around the circumference of the brake shoe at uniform intervals and are cast around it in a ring-like manner. As can be seen from FIG. 2, the axial thickness of the ceramic plates 4 is selected to be somewhat larger than the thickness of the rest of the brake ring 3. As a result, the ceramic plates 4 in their entirety form the necessary friction surfaces for the brake shoes, not shown.
  • FIG. 2 also reveals a circumferential, co-molded bead 4a, which is used to anchor each ceramic plate 4 in the carrier material of the brake ring.
  • the position of the individual ceramic plates 4 relative to one another is shown in FIG. They are spaced from each other in such a way that the right upper corner section of a ceramic plate 4 overlaps the lower left corner section of the subsequent ceramic plate 4 in a radial view and clockwise. This is additionally ensured by an upper corner section of each ceramic plate 4, which is extended beyond the actual diamond shape.
  • the brake disc 1 is cast in one piece from the brake disc carrier 2 and the brake ring 3. During the casting process, the ceramic plates 4 are cast in at the same time.
  • the material for the brake disc carrier and the brake ring, insofar as it serves as a carrier for the ceramic plates 4, consists of an aluminum alloy.
  • the brake ring 3 carries brake plates 43, which have an elongated, diamond-like shape in the radial direction. As the center rays shown in the figure indicate, these brake plates 43 in turn overlap in the radial direction.
  • brake pads 44 and 44 'of different shapes are provided.
  • the brake plates 44 have approximately the shape of a triangular triangle, the tips of which point to the center of the brake disc 3, not shown. Between each two brake plates 44, a brake plate 44 'is arranged in a slender shape of the deck and with the tip radially outward.
  • brake pad 3 provides brake plates 45, which are arranged in three radial positions one above the other and offset from one another. These brake plates 45, like the brake plates 44 and 44 'according to FIG. 4, are in turn at such a distance from one another that they overlap in the radial direction.
  • Ceramic materials with high wear resistance and low porosity are particularly suitable as materials for the ceramic brake discs. Good thermal shock sensitivity is advantageous.
  • boron carbide can be used.
  • Si-lumcarfaid is preferred (reactivity-bound, sintered or hot isostatically pressed) or Silmumratrid (reaction-bound, sintered or hot isostatically re-compressed).
  • the ceramic brake pads can have a plurality of parallel channels inside. If these ducts are used for air cooling, they should remain free when pouring. For the most effective cooling, the plates are preferably attached so that the channels are arranged radially. The channels can also be filled when pouring metal in order to improve the mechanical connection between metal and ceramic.
