Definitions
- Brake shoe in particular for commercial vehicle disc brakes.
- 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.
- Brake pad and brake disc results
- high strength requirements have to be met on brake shoes, because due to the large vehicle masses, correspondingly high braking forces occur during braking for protection against breakage and / or deformation
- bracing forces of up to 10 t there is also a high strength in the area of the end faces of the brake pads vitally important
- the invention therefore aims to provide a brake shoe that is easy to manufacture and that can also cope with higher strength loads
- the invention achieves this goal by the subject matter of claim 1.
- a basic idea of the invention is therefore to assemble the brake pad carrier from a plurality of individual sheets, and the brake pad material not only on one but on two (or more) individual brake pad sheets of the contributor - with one sufficiently large adhesive surface to be attached parallel or at an angle to the main plane of the brake shoe that guarantees sufficient strength.
- a particularly cost-effective and secure connection of the individual sheets is thus achieved, since the process of connecting the covering material to the covering carrier is combined with the process of connecting the individual sheets which would otherwise have to be carried out.
- connection of the lining material and the lining carrier automatically benefits the connection of the individual sheets to one another, that is, the connection of the individual sheets has a strength that the strength of the connection between the covering material and the Brake pad carrier corresponds to the order of magnitude.
- two process steps that are otherwise to be carried out separately are advantageously linked to one another, which leads, among other things, to significant cost advantages.
- Another advantage of the invention is the division of the lining carrier into (as few as possible) firmly joined individual sheets, but not in the sense of the noise-insulating multi-layer carrier known from the prior art (for use in the car sector - see, for example, DE 26 40 824 ).
- the brake lining supports known from these documents tend to reduce the bending stiffness, since the sum of the individual stiffnesses of the sheets (due to the connections between the individual sheets ensuring the spring action) is smaller than the stiffness of a correspondingly dimensioned solid sheet.
- DE 26 40 824 it is stated that the connection of the lamella sheets must be such that the spring action of the disk pack is retained.
- the brake pad would lose its spring properties and thus the noise-reducing effect. All So it is essential in the case of the lamellar flooring that the strength of the flooring is rather reduced in order to achieve noise insulation.
- the use of such brake pads is theoretically conceivable; in the field of commercial vehicle braking technology, on the other hand, the use of the "disk pack brake pads" is not very suitable, because the strength of such brake pads does not meet the high strength requirements described above.
- multi-plate covering supports In order to clarify the difference between multi-plate covering supports and the present invention, it should also be emphasized that, starting from the multi-plate covering supports, the development in the passenger car sector has tended to be in the direction of a multi-plate package with intervening non-metallic dam layers or to an additional dam plate with displacement options (see, for example GB 1 586 465).
- the individual sheets are joined so that they cannot move relative to one another during braking so that no relative movement is possible between them, which leads to a maximum flexural rigidity which gives an optimal directivity a kind of "quasi-compact element" can also be easily realized in this way
- 1 to 4 are sectional views of various exemplary embodiments of the invention.
- FIG. 5 shows a top view of the exemplary embodiment according to FIG. 4 1 is first described.
- 1 shows a cross-sectional view of a first exemplary embodiment of the invention, a brake shoe 1 having a lining carrier 2 and a lining material 3 arranged on the lining carrier 2.
- the covering carrier 2 consists of two individual sheets 4 and 5, the individual sheet 4 facing the covering material 3 having cutouts 6 (for example bores).
- the lining material 3 is firmly connected to the single sheet 4 as well as - through the recesses 6 - to the single sheet 5 (eg glued; if necessary, the surfaces are suitably pretreated).
- FIG. 1 shows a cross-sectional view of a first exemplary embodiment of the invention, a brake shoe 1 having a lining carrier 2 and a lining material 3 arranged on the lining carrier 2.
- the covering carrier 2 consists of two individual sheets 4 and 5, the individual sheet 4 facing the covering material 3 having cutouts 6 (for example bores).
- the lining material 3 is
- the sheet metal 5 has embossments 7 which are adapted to the cutouts 6 in the sheet metal 4 and into which e.g. Intervene in half, so that on the one hand the advantage of simultaneous engagement of the covering material 3 in the recesses 6 is maintained and on the other hand the shear resistance of the sheets 4, 5 against one another is increased.
- Fig. 3 shows a further optimized variant of the invention, in which the forms of the sheet 5 reach through the recesses of the sheet 4 into the actual covering material 3, which guarantees particularly advantageous shear ratios.
- Fig. 4 shows a variant of the invention, in which the adhesive connection between the covering material 3 and the sheets 4, 5 by a fastening means 8 (e.g. a Rivet connection) between the sheets 4 and 5 is added.
- a fastening means 8 e.g. a Rivet connection
- the advantage of this variant of the invention is the further increased security and the ability to preassemble the covering carrier before the covering material is applied.
- the individual sheets 4, 5 are assembled with the invention in a simple manner so that they cannot move in such a way that no relative movement between them is possible during braking.
