Abstract

The invention relates to a brake lining assembly, particularly for drum brakes, comprising a brake shoe having an outer contour, a brake lining having an inner contour, and an intermediate layer having an outer contact region and an inner contact region. The intermediate layer is arranged between the brake shoe and the brake lining, and the intermediate layer is formed, as viewed radially with respect to an axis of rotation of the brake shoe, in such a manner that the inner contact region is matched in a form-fitting manner to the outer contour of the brake shoe in a circumferential direction of the brake shoe. The outer contact region is matched in a form-fitting manner to the inner contour of the brake lining along the circumferential direction.

First claim

The invention claimed is:

1. A brake lining assembly, comprising:
a brake shoe having an outer contour;
a brake lining having an inner contour; and
an intermediate layer having an outer contact region and an inner contact region;
wherein the intermediate layer is arranged between the brake shoe and the brake lining;
wherein the intermediate layer is configured, as viewed radially with respect to the brake shoe, in such a manner that at least a certain area of the inner contact region is matched in a form-fitting manner to the outer contour of the brake shoe in a circumferential direction of the brake shoe; and
at least a certain area of the outer contact region is matched in a form-fitting manner to the inner contour of the brake lining along the circumferential direction; and
wherein the intermediate layer has at least one arrangement region configured for arranging an additional element where the additional element is configured for at least one of an exchange of information and/or data in, on and/or from the brake lining assembly, and the intermediate layer includes a separating element configured to allow dismounting of the intermediate layer, wherein the separating element comprises a thread that cuts through the intermediate layer.

2. The brake lining assembly of claim 1 , wherein the arrangement region comprises at least one connection portion providing a spatial connection with at least one of the brake lining and the brake shoe.

3. The brake lining assembly of claim 2 , wherein the additional element is connected to at least one of the brake lining and the brake shoe by at least one connection element.

4. The brake lining assembly of claim 3 , wherein the at least one connection element comprises a cable.

5. The brake lining assembly of claim 3 , wherein in the at least one arrangement region a sacrificial anode is arranged which provides a corrosion protection effect via the connection portion.

6. The brake lining assembly of claim 5 , wherein at least one of a mechanical and acoustic dampening effect is provided by the specific weight of the intermediate layer.

7. The brake lining assembly of claim 6 , wherein the intermediate layer comprises at least a first and a second material.

8. The brake lining assembly of claim 7 , wherein the intermediate layer along the circumferential direction has a varying stiffness such that the application of the brake lining against a brake drum is influenced.

9. The brake lining assembly of claim 8 , wherein the intermediate layer, as viewed radially with respect to an axis of rotation, has a thickness which is adapted such that the friction surface of the brake lining is configured to be positioned substantially parallel to at least one of the outer contour of the brake shoe and a friction surface of a brake drum.

10. The brake lining assembly of claim 1 , wherein the additional element is connected to at least one of the brake lining and the brake shoe by at least one connection element.

11. The brake lining assembly of claim 10 , wherein the at least one connection element comprises a cable.

12. The brake lining assembly of claim 10 , wherein in the at least one arrangement region a sacrificial anode is arranged which provides a corrosion protection effect via the connection portion.

13. The brake lining assembly of claim 1 , wherein at least one of a mechanical and acoustic dampening effect is provided by the specific weight of the intermediate layer.

14. The brake lining assembly of claim 1 , wherein the intermediate layer comprises at least a first and a second material.

15. The brake lining assembly of claim 1 , wherein the intermediate layer along the circumferential direction has a varying stiffness such that the application of the brake lining against a brake drum is influenced.

16. The brake lining assembly of claim 1 , wherein the intermediate layer, as viewed radially with respect to an axis of rotation, has a thickness which is adapted such that the friction surface of the brake lining is configured to be positioned substantially parallel to at least one of the outer contour of the brake shoe and a friction surface of a brake drum.

17. An intermediate layer configured for being arranged between a brake lining and a brake shoe of a drum brake, comprising:
an outer contact region; and
an inner contact region;
wherein at least a certain area of the outer contact region is configured to be connected to a brake lining in a form-fitting manner;
wherein at least a certain area of the inner contact region is configured to be connected to a brake shoe in a form-fitting manner;
wherein the intermediate layer has at least one arrangement region which is adapted for arranging an additional element;
and wherein the intermediate layer includes a separating element configured to allow dismounting of the intermediate layer, and wherein the separating element comprises a thread that cuts through the intermediate layer.

18. A brake lining assembly, comprising:
a brake shoe having an outer contour;
a brake lining having an inner contour; and
an intermediate layer having an outer contact region and an inner contact region;
wherein the intermediate layer is arranged between the brake shoe and the brake lining;
wherein the intermediate layer is configured, as viewed radially with respect to the brake shoe, in such a manner that at least a certain area of the inner contact region is matched in a form-fitting manner to the outer contour of the brake shoe in a circumferential direction of the brake shoe; and
at least a certain area of the outer contact region is matched in a form-fitting manner to the inner contour of the brake lining along the circumferential direction, wherein at least one of the inner contact region and the outer contact region is substantially arcuately shaped as viewed radially with respect to the brake shoe; and
wherein the intermediate layer has at least one arrangement region configured for arranging an additional element where the additional element is configured for at least one of an exchange of information and/or data in, on and/or from the brake lining assembly, and the intermediate layer includes a separating element configured to allow dismounting of the intermediate layer, and wherein the separating element comprises a thread that cuts through the intermediate layer.
