Definitions

  • the invention relates to a damping plate for disc brake pads.
  • damping plates or damping films are used. These are continuous steel sheets that can be coated with rubber. Such sheets are usually provided at most there with recesses, where this geometrically, for example. is required for attachment. The adaptation to the noise damping takes place over the materials of the damping plate and over the thickness of the individual layers (steel, rubber, adhesive).
  • such a damping plate comprises at least one sheet-metal layer, wherein the sheet-metal layer comprises over its surface a multiplicity of perforations which are designed such that they reduce sound of at least one predetermined frequency.
  • the perforations may extend over the entire surface of the sheet metal layer. Depending on the embodiment, the perforations may be evenly distributed at least in part be arranged or arranged irregularly. Optionally, the perforations may comprise at least two different sizes.
  • the damping plate may also include at least a second sheet metal layer.
  • the second or even further sheet metal layers can be provided with perforations.
  • an intermediate layer may be arranged between the first and the second sheet-metal layer, which could be made, for example, from a woven fabric, a wire, an elastomer or a sheet material.
  • Damping sheets in exemplary embodiments may be provided with an elastomeric coating.
  • Figure 1 shows a shield with evenly distributed round holes
  • Figure 2 shows a further shielding plate, in which only a part of the sheet surface is provided with holes in different sizes
  • Figure 3 shows a shield with rectangular holes.
  • FIG. 1 shows a shielding plate for a disc brake pad.
  • the sheet in this example essentially corresponds to the size and shape of a brake pad; but it could also be made larger or smaller.
  • Such a shielding plate may have fastening openings for fastening the sheet to the brake system or on the brake lining, for example an opening 4 for the passage of a bolt or a screw.
  • additional perforations 6 are introduced into the shielding.
  • the additional holes 6 are not used for attachment or similar purposes, but cause better sound attenuation compared to continuous, unperforated sheets.
  • the sheet metal surface of a shielding plate according to the invention is correspondingly provided with a plurality of perforations, as shown in the figures.
  • the perforations may be distributed at regular intervals over a fixed part of the shielding plate or over the entire sheet 2. Depending on the design, this can result in a very cost-effective solution, since a perforated plate with uniform perforation can be used as the starting material, from which the shielding plate is punched out as required.
  • FIG. 1 shows an example in which essentially the entire shielding plate 2 is provided with evenly distributed, equally large round perforations 6.
  • the hole patterns could follow a certain pattern and / or be irregularly distributed over the sheet surface.
  • the perforations can be designed as round holes 6, 6a, 6b, as shown in Figures 1 or 2; but also square, hexagonal or other shaped perforations could be introduced into the sheet.
  • Figure 3 shows as an example evenly distributed over the sheet 2 rectangular holes 6c. Even grid-like perforations, wavy lines or other geometric patterns are conceivable.
  • Various perforations can also be combined in a sheet metal layer.
  • the hole diameter can be varied; For example, in Figure 2, small round perforations are combined in a uniform pattern with large round perforations, but not the entire surface is perforated here.
  • the shielding plate 2 may be, for example, a steel sheet of predetermined thickness. Likewise, other materials, such as glass fiber materials or aluminum sheets.
  • the shielding plate 2 could also be additionally coated with a glued or otherwise applied elastomer layer of desired thickness.
  • further openings 4 may be introduced, for example, for attachment.
  • the coating for example an elastomer layer, can likewise be perforated in the area of the perforations or else extend into the perforations or over them.
  • a shielding plate may comprise a plurality of at least partially perforated sheet metal layers 2.
  • a perforated plate could be considered with a non-perforated plate, or two perforated plates could be combined to form a shield.
  • a nonwoven or fabric material may be introduced between the two or more sheet metal layers 2 .
  • additional layers or coatings such as elastomer layers or film layers could be arranged therebetween, wherein the intermediate layers could be continuous or likewise perforated.
  • Such liners may have different effects depending on the design; For example, they can attenuate further specific frequencies for which the concrete perforated plate is permeable, but could also be e.g. serve as heat insulation.
  • materials of the intermediate layers could at least partially extend into the holes of the respective shielding plate and thus fill the holes. It is also conceivable, even in embodiments without an intermediate layer, to completely or partially fill at least part of the holes, for example with an elastomer, rubber or other suitable materials.
  • the layers can be connected to each other in a suitable manner. It is conceivable to connect the layers, for example by riveting, crimping or gluing together. In this case, in certain embodiments, the sheets could be crimped, in particular in the region of the perforations, so that an edge of a sheet-metal layer extends through the opening of the other sheet-metal layer. In this case, only a portion of the holes or all perforations could be carried out in this way.
  • the diameter of the holes in an exemplary shielding plate may be between about 1mm and 20mm, preferably between 5 and 15mm.
  • a plurality of holes are introduced, in usual embodiments, at least 10 holes over the sheet surface away.
  • the distance between the holes to each other, measured between the hole edges, is at least as large as the hole diameter, preferably the distance corresponds to at least the hole diameter + 1mm.
  • a hole diameter of 6mm so a hole spacing of at least 7mm could be used, but also larger distances such as 15mm are possible in this case.
  • the hole spacings can be varied over the metal sheet; Similarly, the hole diameter could be varied with uniform hole spacing. If patterns of different hole sizes are introduced into the sheet, the hole spacing can be designed accordingly different.
  • At least some of the holes or the sheet metal regions could be pulled deep around introduced holes. In this way, for example, round, cylindrical or conical depressions could arise in a sheet, at the end of the corresponding hole is introduced.
  • depressions are all formed to one side, or that recesses are alternately or irregularly formed on both sides of the sheet.
  • non-perforated sheet metal areas could alternatively or additionally be deformed by deep drawing. Similar embodiments are also possible with a combination of several sheet metal layers, so that one or more of the sheet metal layers used at least partially deep drawn areas.
  • the different possibilities of carrying out the shielding plates can also be combined with one another, for example the deep drawing of sheet metal areas with the introduction of a coating or another Liner;
  • the various hole patterns, distances and hole designs are applicable to all described embodiments.
  • the increased noise attenuation can result from different effects. For example, refraction of the sound waves at the edges of the perforations could cause sound to be reflected and refracted and attenuated to exit.
  • the arrangement, shape and orientation and diameter of the perforations can be optimally adjusted by simulations or test results to the frequencies occurring in a specific brake system, so as to further increase the damping. Further, it is possible that the vibration behavior of the perforated shielding plate is changed by the plurality of perforations and so takes place a reduced noise due to resonant vibrations.
  • a sound attenuation in various audible ranges between about 500Hz and 17kHz take place, the respective damped frequency ranges of the design of the sheet and the entire brake system are dependent.
  • the sound attenuation can take place evenly over a large area or concentrate on certain frequency ranges, which are attenuated above average.
