Abstract

Brake lining arrangement with wear indicator, comprising a planar lining carrier with a brake lining attached to a substantially plane holding surface, wherein the wear indicator has a supporting section, with which it is supported on the lining carrier, and an indicator section which extends beyond the holding surface in such a manner that it overlaps the material thickness of the brake lining and indicates a lining wear limit value, wherein the indicator section and supporting section are connected to each other via a transition section, wherein the transition section has a transition section axis. According to the invention, it is provided that the transition section axis is inclined at an acute angle to the holding surface.

First claim

The invention claimed is:

1. A brake lining arrangement with wear indicator comprising:
a planar lining carrier with a brake lining attached to a substantially plane holding surface,
wherein the wear indicator has a supporting section, with which the wear indicator is supported on the lining carrier, and an indicator section which extends beyond the holding surface in such a manner that the indicator section overlaps a material thickness of the brake lining and indicates a lining wear limit value,
wherein the indicator section and supporting section are connected to each other via a transition section, wherein the transition section has a transition section axis which extends longitudinally through a center of the transition section,
wherein the transition section axis is inclined at an acute angle to the holding surface.

2. The brake lining arrangement according to claim 1 , wherein the transition section axis is inclined at an angle of 40° to 70° to the holding surface.

3. The brake lining arrangement according to claim 1 , wherein the transition section is of rounded form.

4. The brake lining arrangement according to claim 3 , wherein the transition section is formed with a radius of 1 mm to 3.5 mm.

5. The brake lining arrangement according to claim 1 , wherein the supporting section and the indicator section extend, at least in sections, in planes parallel to each other.

6. The brake lining arrangement according to claim 1 , wherein the transition section is arranged on a side of the lining carrier facing away from the brake lining.

7. The brake lining arrangement according to claim 1 , wherein the supporting section is arranged completely on a side of the lining carrier facing away from the brake lining.

8. The brake lining arrangement according to claim 1 , wherein the transition section encloses an angle of greater than 180°.

9. The brake lining arrangement according to claim 1 , wherein the indicator section extends substantially in one plane and the transition section extends, at least in sections, beyond the one plane of the indicator section.

10. The brake lining arrangement according to claim 9 , wherein the transition section extends by a distance of 0.25 mm to 1.5 mm beyond the one plane of the indicator section.

11. The brake lining arrangement according to claim 1 , wherein the wear indicator is formed as a component separate from the lining carrier.

12. The brake lining arrangement according to claim 1 , wherein the supporting section comprises a fastening section, with which the wear indicator is fastened to the lining carrier.

13. The brake lining arrangement according to claim 12 , wherein the fastening section comprises a receiving opening which receives a plastically deformed securing pin of the lining carrier, wherein the receiving opening is formed with a non-circular profile.

14. The brake lining arrangement according to claim 13 , wherein the receiving opening is formed with a D-shaped profile.

15. A wear indicator for a brake lining arrangement according to claim 1 .
