Definitions

  • the invention relates to a brake pad for a disc brake according to the preamble of claim 1.
  • brake pads are used both in disc brakes for passenger cars as well as for commercial vehicles.
  • the brake pad consists of a lining carrier plate and a friction lining mounted thereon, which is pressed in the case of braking against a rotating brake disc.
  • the pad carrier plate to which the friction lining is usually applied by pressing, serves on the one hand, the distribution of application forces, the
  • Brakes are applied by means of an application device and on the other hand for the transmission of braking torques arising during braking on, for example, brake carrier horns, which delimit a lining shaft in which the brake lining is positioned, of a stationary brake carrier.
  • the invention has for its object to develop a brake pad of the generic type so that it is weight-optimized weight with unchanged reliability and its performance is improved.
  • This object is achieved by a brake pad with the features of claim 1.
  • This brake lining is initially characterized by the fact that the rigid core, which may consist of metal, such as aluminum, steel or cast iron, but also, for example, a fiber-reinforced material such as carbon or the like, exactly adapted to the load curve during braking or dimensioned can be made, while the remaining areas that are not or only slightly loaded, are formed from the existing of a material for embedding the core plasticizable layer which is formed at least one side to a plate.
  • this material consists of a polymeric or elastomeric plastic, which at least partially surrounds the core, wherein the force-transmitting surfaces themselves are not coated. It is also conceivable, however, to form this envelope from the material constituting the friction lining which is produced by sintering after insertion of the core into the plastified friction lining mass.
  • the core itself which, as mentioned, is designed exclusively to optimize the load, can be designed in the form of a framework, as a honeycomb structure or as a suitable, thinly ribbed plate. As a result, the transmission of the high forces occurring during braking at extremely low weight is possible.
  • the so-called composite lining carrier plate allows a weight saving per disc brake of up to 1 kilogram, with a 22.5 "disc brake, resulting in a corresponding increase in payload and a reduction in unsprung masses
  • a weight saving per disc brake of up to 1 kilogram
  • a 22.5 "disc brake resulting in a corresponding increase in payload and a reduction in unsprung masses
  • fuel savings so that overall business benefits arise.
  • the invention By adapting and optimizing the shape of the metallic core to the respective axle construction, it is possible to shift critical excitation frequencies into uncritical regions for noise generation, which can lead to an improvement in the so-called NVH behavior.
  • the surrounding plastic layer has an additional damping effect.
  • the lining carrier ie the preferably metallic core including the coating can be made separately and then the friction lining as a cake, as before, pressed or glued under high pressure. There- In the case of the coating, the coating forms a plane surface, albeit thin, on which the friction lining bears.
  • the core as an insert and to provide it in a manufacturing step with the layer and the friction mass.
  • the core can also be embedded without plastic coating in the friction material.
  • the core is applied to the already prefabricated friction lining and then the layer in a mold in which the unit friction lining / core is cast or injected.
  • the core itself may be formed as a stamped part or as a forming and / or sheet metal part. Of course, there is also the possibility to produce the core by casting. In any case, the core is to be manufactured as a series part, wherein the use of material optimized by the load-optimized design is limited to the actual necessary level, which naturally results in a very cost-effective production. Further advantageous embodiments of the invention are characterized in the subclaims.
