Definitions

• the invention relates to a brake shoe, in particular for
• Brake pad carriers form a brake shoe in connection with a brake pad material attached to them.
• the brake lining carrier and the brake lining material attached to it are passed on. from which the braking force between the brake pad and brake disc results.
• high strength requirements have to be met on brake shoes, because infoige of the large vehicle masses have correspondingly high braking forces during braking being able to develop disturbing noises
• One of the requirements for a brake shoe that is also suitable for the commercial vehicle sector is therefore the lowest possible noise development during driving or when braking
• the invention aims to provide a brake shoe that is easy to manufacture and that causes only a low level of noise even in continuous operation
• the invention achieves this goal by the subject matter of claim 1.
• a basic idea of the invention is therefore to design the generic brake pad or the generic brake shoe in such a way that the pad carrier has an at least limited elastic support element.
• the support element can be designed in this way with regard to the material and the geometry That the noise development is significantly reduced by colliding parts - especially when the brake is released.
• the invention particularly reduces the noise development between the lining carrier and the brake carrier, whereby, in contrast to the known dam plates for car linings, the noise development in the side area of the lining in the lining shaft is also reduced becomes
• the support element is supported in the lining carrier, it protrudes beyond the support surfaces, it is supported on the brake carrier and it is elastically deformable in the direction of the braking torque and / or in the direction of the contact pressure of the brake shoe.
• the noise pressure can be implemented particularly well, the elasticity should be such that the support element is compressed somewhat during braking and thus does not hinder the support of the metallic support surfaces of the pads and the brake support during braking. The support element is then only with a defined elastic force and not loaded with a full contact force and / or force resultant from the braking torque
• FIG. 3 shows a sectional view of a further exemplary embodiment of the invention
• Fig. 4 shows an exemplary embodiment of the invention in the installed position
• FIG. 1 a shows a plan view of a brake shoe 1 for commercial vehicle disc brakes, the lining carrier 2 composed of two individual plates 2a, 2b and a lining material 3, the lining carrier 2 with (metallic) support surfaces 4 during braking supported on the lining carrier 6 (see FIG. 4)
• the lining carrier plates 2b are provided with a supporting element 5 (rubber, elastomer) for noise reduction, which also engages with the lining carrier plates 2a with a projection 5a.
• the connection between the lining carrier 2 (or, if applicable, the lining material) should 3) and the support element 5 can be designed in such a way that the support element 5 can be replaced easily and uncomplicatedly (for example screwing, vernieru ⁇ g).
• gluing and / or material pressing are alternatively conceivable
• the support element 5 when the brake is released, protrudes slightly beyond the support surfaces 4 of the lining carrier plate 2 (a few mm) and (in plan view) it is almost rectangular (with beveled corners).
• the support element engages in recesses 9, which are recessed in the corners of one of the plates 2b of the lining carrier 2a, so that there is a noise-reducing effect even when the brake is released in two mutually perpendicular directions of movement.
• the support element 5 is also designed such that the support surface 4 is at a full deformation path of the support element 5 of the lining carrier 2 is fully in effect with the brake support 6.
• the support element 5 also preferably has a resilient effect in the direction of the application force, the support surface 4 acting as a limitation of the elastic deformation of the support element 5 and forming a kind of fixed stop
• the support element 5 is designed as a sealing part which has an essentially resilient and / or damaging area, which is designed as an elasto element 51, and an essentially solid, low-friction area, which is designed as a sliding element 52 3 differs from this in order to achieve favorable temperature properties in that a shielding element 7 is arranged between the support element 5 and the lining carrier 2.
• the shielding element 7 preferably consists of a temperature-resistant material, and / or a material is selected which has a low thermal conductivity
• a variant of the invention that is particularly advantageous in terms of production technology is further characterized in that the support element 5 and the shielding element 7 are designed as an integrated compact part 8
• FIG. 4 illustrates the mode of operation of the invention on the basis of the installation position of the brake shoe 1 in the disc brake mechanism.
• the support element 5 is supported on the side wall of the lining shaft 10 of the brake support 6
