Definitions

  • the invention relates to a brake pad for a disc brake of a vehicle, in particular a commercial vehicle, having a lining carrier plate which is configured as a cast part and having a friction lining which is fastened in the lining carrier plate.
  • disc brakes for vehicles in particular for commercial vehicles, also include two brake pads, which can be pressed against the friction faces of a brake disc when required, that is to say in the case of a braking operation.
  • each brake pad includes a lining carrier plate and a friction lining which is fastened thereto and bears frictionally against the associated friction face of the brake disc in the use position.
  • the friction lining is held positively only on the positively connected parts, with the result that there is the risk that, if the friction lining tears, parts are released from it, which not only limits the functional capability of the disc brake overall to a great extent, but possibly leads to its failure, since the released parts can jam in the brake caliper and impede the displacement movement of the brake pads and/or the brake disc.
  • the invention is therefore based on the object of further developing a brake pad such that it can be produced less expensively while improving its functional reliability.
  • a brake pad for a disc brake of a vehicle in particular a commercial vehicle, has a lining carrier plate which is configured as a cast part, and has a friction lining, which is fastened in the lining carrier plate.
  • the lining carrier plate has a flat-shaped basic body and elevated or raised positively connected parts, which are integrally cast thereon and are enclosed by the friction lining. At least one part of the positively connected parts is surrounded, at least in regions, by an adjoining depression of the basic body.
  • the lining carrier plate can be cast in a substantially simpler and less expensive manner. This relates to both the casting itself and preparatory work, such as the production of a sand mold and the like, and also to the unproblematic production of the casting mold which is then possible and in which the use of correspondingly elastic mold means can be dispensed with, so that a considerably higher service life of the corresponding model results. Overall, the invention leads to a substantial cost reduction of the brake pad, which cost reduction has a particular significance in view of the series production of such brake pads.
  • the embedding of the friction lining into the depressions of the basic body which surround at least a part of the positively connected parts at least in regions ensures additional security for holding the friction lining on the lining carrier plate, which depressions make possible improved absorbtion of shearing forces that occur and additionally guarantee improved securing of friction lining parts if the friction lining is destroyed, for example, by the formation of cracks. That is to say, the friction lining parts continue to adhere to the carrier plate even when the brake is not in engagement, that is to say, is released.
  • the shape, dimensions and arrangement of the positively connected parts can be of different designs.
  • the configuration of the positively connected parts is substantially dependent on the force absorption which occurs during braking, the temperature which is produced, and the properties of the friction materials used (which can be different as a result of various production processes and compositions).
  • the positively connected parts can be integrally molded in the form of round or rectangular pins or pegs, which are arranged offset with respect to one another, in a row or extending obliquely in one or more directions. It is also contemplated to configure the positively connected parts as meandering webs, which are integrally cast such that they extend parallel to one another, for example.
  • FIGS. 1-3 show, in each case, one exemplary embodiment of a lining carrier plate of a brake pad according to the invention in a perspective view or a plan view;
  • FIG. 4 shows a section through the lining carrier plate according to FIG. 3 in a perspective view.
  • FIG. 1 shows, in each case, one exemplary embodiment of a lining carrier plate 1 , which is a constituent part of a brake pad which, moreover, has a friction lining (not shown) connected fixedly to the lining carrier plate by means of positively connected parts 3 .
  • the positively connected parts 3 of the lining carrier plate 1 which is composed of a cast material, are integrally cast onto a flat-shaped (basically planar) basic body 2 and, in the example shown in FIG. 1 , are shaped as pegs which lie next to one another in offset rows and are of square or rectangular configuration in cross section.
  • the positively connected parts 3 are surrounded, in each case, by an adjacent depression 4 of the basic body 2 , into which depression 4 the friction lining material which is to be applied is inserted.
  • the free end side of the positively connected parts 3 which faces away from the base plate 2 , is provided with a recess 5 which, as can be seen very clearly, in particular in FIG. 4 , is of a cavity-shaped configuration but can also certainly extend deeper into the positively connected parts.
  • the positively connected parts 3 are configured as webs, which extend in a meandering manner over the planar basic body, and of which a plurality are arranged in parallel and at a spacing from one another. In each case, they are surrounded by a depression 4 , while the free end side has a recess 5 here also.
  • FIG. 3 is comparable with the exemplary embodiment in FIG. 1 , in the former the positively connected means 3 likewise being shaped as pegs or pins but of round cross section and likewise being provided with recesses 5 , like the positively connected means 3 which are shown in the other examples.
  • the depressions 4 surrounding the positively connected parts 3 are configured in this case in the manner of circular rings, as can be seen in FIG. 4 .
  • the recesses 5 ensure fixed anchoring of the friction lining, in particular also with regard to absorbing the shearing forces that occur.
