Definitions

• the invention relates to a brake pad of a disc brake according to the preamble of claim 1.
• Such brake pads find particular use in disc brakes, which are used in commercial vehicles.
• a brake lining consists of a particular metallic lining carrier plate, either of cast iron or sheet metal, of an intermediate layer fixed to its base surface and of an abrasive friction lining which is held on the intermediate layer.
• This intermediate layer serves primarily to reduce the heat transfer and the damping during braking occurring vibrations, which are synonymous with the generation of squeaking noise, which is prevented by the intermediate layer.
• the thickness of the friction lining is determined so far by a predetermined maximum wear plus a safety allowance, upon reaching the brake pad must be replaced in total. In this case, a residual thickness of the friction lining adheres to the intermediate layer, which is disposed of in its entirety, together with the residual friction lining and the lining carrier plate.
• the brake pad Since due to the space conditions in the disc brake, concretely in the brake caliper and / or a brake pads receiving brake carrier, the brake pad must not exceed a certain total thickness, on the other hand, the pad carrier plate due to a required bending stiffness also must not fall below a certain thickness, remains for the thickness of the intermediate layer a relatively small dimension, in the known
• Brake pads for example, or usually about 2 mm, while the thickness of the friction lining is about 19 mm.
• the invention has for its object to develop a brake pad of the generic type so that it is cheaper to produce and its usefulness is improved.
• the inventive design of the brake lining can now be dispensed with the relatively expensive material of the intermediate layer and parts of the friction material. Instead, a material is used, which is cheaper, but due to the greater thickness at least similar damping properties as the previously used intermediate layer. It is even conceivable to use a material which is more cost-effective than the material of the friction lining as a new intermediate layer, for which purpose, for example, recycled friction material is suitable, mixed with abrasive friction grains and resins as binder. Since the thickness of the unused friction lining according to the invention is less than or equal to a predetermined maximum wear, comes after removal of the friction lining including the thickness of the safety allowance now also sufficiently frictionable intermediate layer used, which has comparable friction properties as the friction lining itself.
• the brake pad In principle, even after reaching the predetermined degree of wear, the brake pad remains in the same thickness as the previous brake pad after abrasion of the friction lining determined by the wear dimension, so that the so-called residual thickness of the brake pad in both cases, thus in the hitherto used and at the new brake pad is the same.
• the intermediate layer can be made of recycled friction material, so that an extremely favorable production of the intermediate layer results, especially since the total thickness of the unused brake pad remains unchanged, the friction lining is correspondingly thinner.
• the intermediate layer is therefore now> 2 mm, while the friction lining is ⁇ 19 mm, but uniform in addition to the lining carrier plate.
• the tendency to crack of the brake lining is also significantly reduced, since the intermediate layer now essentially has the relevant properties, which also has the friction lining.
• the single FIGURE shows a brake pad according to the invention in a plan view.
• a brake pad of a disc brake is shown, with a lining carrier plate 1, which consists of metal or other suitable material and may be formed, for example, from cast iron or sheet metal.
• a lining carrier plate 1 which consists of metal or other suitable material and may be formed, for example, from cast iron or sheet metal.
• an intermediate layer 2 is fixed, usually by gluing and / or positive engagement, which carries an abrasive friction lining 3, which contacts in function, ie during braking, a vehicle-mounted brake disc under contact pressure.
• the friction lining 3 is preferably materially connected to the intermediate layer.
• the illustrated brake lining is a new product, so to speak.
• the friction lining 3 is unused and is present in a maximum thickness b.
• the thickness of the intermediate layer 2 is designated by a.
• the thickness of the unused friction lining 3 is less than a predetermined maximum amount of wear c max , wherein the thickness b of the friction lining 3 plus a part of the thickness a of the intermediate layer 2 corresponds to the wear coefficient c max .
• the thickness b of the friction lining 3 in the unused position is preferably ⁇ 19 mm, while the thickness a of the intermediate layer 2 is> 2 mm.
• other dimensions are conceivable, which is dependent on the space of the respective disc brake, in which the brake pads are used with respect to the total thickness of the brake pad.
