Abstract

A disc brake, in particular its brake lining, is provided with at least one temperature indicator which changes state after a permitted operating temperature is exceeded and/or remains in its position after a permitted operating temperature is exceeded. The temperature indicator may be, in particular, a coating of an adhesive or paint, an affixed label or an affixed tag.

Claims

1. A disc brake for a vehicle, comprising:

a caliper which, in use, straddles a brake disc;

an application device arranged in the caliper;

brake linings configured to be selectively applied against the brake disc, one brake lining being arranged on each side of the brake disc when in use; and

at least one temperature indicator provided for the disc brake, the at least one temperature indicator operating to at least one of change state after a permitted operating temperature is exceeded and remain in a certain position after the permitted operating temperature is exceeded.

2. The disc brake according to claim 1, wherein each of the brake linings includes a lining support and lining material, the at least one temperature indicator being arranged on the lining support of at least one of the brake linings.

3. The disc brake according to claim 1, wherein a first temperature indicator is arranged on a first of the brake linings and a second temperature indicator is arranged on a second of the brake linings.

4. The disc brake according to claim 1, wherein a first temperature indicator is arranged on at least one of the brake linings of the disc brake and a second temperature indicator is arranged on another component of the disc brake.

5. The disc brake according to claim 1, wherein the temperature indicator comprises a paint coating.

6. The disc brake according to claim 2, wherein the temperature indicator comprises a paint coating.

7. The disc brake according to claim 4, wherein the temperature indicator comprises a paint coating.

8. The disc brake according to claim 1, wherein the temperature indicator comprises an adhesive coating.

9. The disc brake according to claim 2, wherein the temperature indicator comprises an adhesive coating.

10. The disc brake according to claim 4, wherein the temperature indicator comprises an adhesive coating.

11. The disc brake according to claim 1, wherein the temperature indicator comprises a label provided with an adhesive layer.

12. The disc brake according to claim 2, wherein the temperature indicator comprises a label provided with an adhesive layer.

13. The disc brake according to claim 4, wherein the temperature indicator comprises a label provided with an adhesive layer.

14. The disc brake according to claim 1, wherein the temperature indicator comprises a mechanical display unit.

15. The disc brake according to claim 2, wherein the temperature indicator comprises a mechanical display unit.

16. The disc brake according to claim 4, wherein the temperature indicator comprises a mechanical display unit.

17. A component of a disc brake for a vehicle, comprising:

a brake lining; and

a temperature indicator operatively configured with the brake lining, the temperature indicator operating to at least one of change state after a permitted operating temperature of the disc brake is exceeded and remain in a certain position after the permitted operating temperature is exceeded.

18. The component according to claim 17, wherein the brake lining includes a lining support, the temperature indicator being arranged on the lining support of the brake lining.

19. The component according to claim 18, wherein the temperature indicator comprises a paint coating.

20. The component according to claim 18, wherein the temperature indicator comprises an adhesive coating.

21. The component according to claim 17, wherein the temperature indicator is a mechanical display unit.
