Definitions

  • the present invention relates to a pair of brake pads for a disc brake according to the preamble of claim 1.
  • a brake designed as a sliding caliper disc brake is known, which can be installed in a vehicle, in particular a commercial vehicle.
  • this disc brake also comprises two brake linings which form a pair of brake linings and which can be pressed against the friction surfaces of a brake disc during braking.
  • the brake disc is encompassed by a displaceably mounted brake caliper, on one side of which a clamping device, preferably operated by compressed air, is arranged, with which the brake lining on the brake side is pressed against the brake disc. Due to the reaction forces that occur when the brake lining is applied to the brake disk, the brake caliper moves in the opposite direction while simultaneously carrying and engaging the brake lining on the brake disk.
  • Each of the two brake linings consists of a lining carrier plate and an associated friction lining, which, in the use position, abuts the associated friction surface of the brake disk.
  • the thickness In order to absorb the considerable loads occurring in the operating position, in particular bending loads, the thickness must be dimensioned accordingly of the base plates required. This applies equally to the design of the lining carrier plate with regard to shear stresses occurring in the connection area between the respective friction lining and the associated lining carrier plate, the connection of which is subject to very high requirements, which also result from thermal loads such as are caused by the resulting frictional heat during braking.
  • the previously used two brake pads of a pair of brake pads are dimensioned and configured without taking these load differences into account.
  • a thickness of 21 mm remains for the friction pad, of which only 19 mm can be used as a wear thickness, since the remaining thickness of 2 mm forms a safety thickness, so to speak. when they reach the brake pad is replaced.
  • the dimensions mentioned refer, for example, to the brake lining on the application side, where the reaction-side brake lining can be oversized due to a changed load application.
  • the pad carrier plate then made of sheet metal in the area of the outer circumference with an at least partially circumferential into which the friction lining To provide the opposite direction cranked edge for reinforcement, through which a certain bending stiffness is achieved, but is not sufficient due to the lack of correspondence in the surface of the lining carrier plate, so that this construction does not meet the requirements to a sufficient extent.
  • the present invention is therefore based on the object of further developing a pair of brake pads so that it is optimized for the respective purpose and location.
  • the two brake pads of the pair of brake pads can now be optimized both with regard to their load capacity and with regard to their service life.
  • the pad carrier plate of the respective brake pad is configured in a way that is precisely adapted to the existing spatial and load conditions.
  • the wear volume of the friction lining can be chosen larger without exceeding the total thickness of the brake lining.
  • reinforcement ribs can be provided on the respective lining carrier plate, which ribs can be placed where the installation space permits this.
  • depressions and / or elevations and holes in or on the lining carrier plate which are preferably provided with undercuts and which correspond to the friction lining in a form-fitting manner, thereby providing sufficient shear strength and sufficient strength in other load directions.
  • the lining carrier plates can be formed as sheet metal parts. However, they are preferably produced as a cast part, which gives rise to the possibility of flexible shaping, by means of which the stiffening ribs and form-fitting parts mentioned can be produced in particular.
  • the elevations, depressions or holes which are shaped in accordance with the requirements, can be arranged in such a way that there is no reduction in the bending stiffness associated therewith.
  • the invention of a load-dependent design of the lining carrier plates offers considerable freedom.
  • the invention also provides a disc brake with a pair of brake pads according to the invention.
  • Figure 1 a disc brake according to the invention in a schematic plan view
  • Figures 2 and 3 the two pad carrier plates of the pair of brake pads each in a rear view
  • FIG. 4 shows a front view of the lining carrier plate according to FIG. 2
  • FIG. 5 shows a cross section through a partial section of the lining carrier plate according to FIG. 3
  • FIG. 6 a cross section through a partial section of the lining carrier plate according to FIG. 2
  • FIG. 1 shows a sliding calliper disc brake, preferably operated by compressed air, which is attached to a commercial vehicle, not shown, by means of a brake carrier 2.
  • the sliding caliper disc brake has a sliding caliper 1, which comprises a brake disc 3, which is fastened to an axle, not shown, of the commercial vehicle.
  • the brake caliper 1 is arranged on the brake carrier 2, with respect to the brake disc 3, so as to be axially displaceable.
  • a brake pad 5, 6 is provided on both sides of the brake disk 3, which together form a pair of brake pads 4 and of which the right, application side, can be pressed against the brake disk 3 by means of an application device 11 via pressure pieces 10 during a braking operation.
  • the application-side brake pad 6 is placed in an installation space 12 of the brake caliper 1, like the reaction-side brake pad 5 in a space 13, which differ in shape and dimensions due to the installed components.
  • the application-side 9 and the reaction-side 7 lining carrier plates have different configurations and dimensions adapted to the loads that occur and the installation spaces 12, 13 of the brake caliper 1. This can be seen particularly clearly in FIGS. 2 to 6.
  • holes 16 are arranged distributed over the entire surface, which, as can be seen in the cross-sectional illustration in FIG. 6, open into recesses 15 on their side facing the friction lining 8, also recognizable in FIG. 4, and widen conically in the opposite direction. The so between the

  • the covering support plate 7 of FIG. 3 can also be seen, the outer edge region of which is partly thicker, as a result of which a reinforcing edge 14 is formed.
  • This has an advantageous effect on a surface pressure arising during braking, which results from the support that occurs. Since there is a greater coverage area for this support by the reinforcing edge 14, the minimum permissible pane thickness can also be optimized.
  • the conical widening of the holes 16 can be seen as an undercut, for example. However, it is also conceivable to introduce undercuts in a different shape, so that the material of the friction lining 8 is embedded in a form-fitting manner.
  • the total thickness of the covering support plate according to the prior art is, for example, 9 mm.
  • the new covering support panels can be reduced to an installation-relevant thickness of 7 mm with the same load-bearing capacity if the ribs are arranged and dimensioned accordingly. This results in an increase in the thickness of the friction lining 8 by 2 mm and a corresponding increase in the service life of the brake linings as a whole.

Abstract

L'invention concerne une paire de garnitures de frein (4) pour un frein à disque comprenant un étrier de frein (1), en particulier un frein à disque pourvu d'un étrier glissant, constituée d'une garniture de frein (6) qui coopère avec un dispositif d'application de frein (11) côté application de frein, ainsi que d'une garniture de frein (5) côté réaction. Ces garnitures de frein comprennent respectivement une plaque de support de garniture (9, 7) et une garniture de friction (8) disposée sur cette dernière qui, en position de freinage, reposent sur le disque de frein (3) de manière à exercer une friction. La paire de garnitures de frein selon l'invention est conçue de manière que la plaque de support de garniture côté application de frein (9) et côté réaction (7) présentent des configurations et des dimensions différentes qui sont adaptées aux sollicitations engendrées respectives et à l'encombrement (12, 13) respectif de l'étrier de frein (1).
