Abstract

A brake dust particle filter for a brake caliper of a disc brake assembly, wherein the brake caliper comprises a lining inspection opening, closes in a mounted state thereof the lining inspection opening at least partially with precise fit. The brake dust particle filter is provided with a filter medium support that supports a filter medium. A brake caliper provided with the brake dust particle filter in the lining inspection opening is arranged across the brake disc of the disc brake assembly.

First claim

What is claimed is:

1. A brake dust particle filter for a brake caliper of a disc brake assembly, wherein
the brake caliper comprises
a lining inspection opening,

wherein the brake dust particle filter is configured to close in a mounted state thereof the lining inspection opening at least partially with precise fit,
wherein the brake dust particle filter comprises
at least one opening extending in a radial direction with a predetermined axial extension,
wherein through the at least one opening at least one indicator can be guided,
wherein the indicator, in the mounted state of the brake dust particle filter, is configured to be brought into interaction with at least one brake lining of the brake caliper for detection of a brake lining thickness.

2. The brake dust particle filter according to claim 1 , wherein
the brake dust particle filter comprises
a filter medium support configured to be flowed through by a fluid at least in sections thereof,
wherein the filter medium support is matched to a shape and dimensions of the lining inspection opening and is configured to be inserted into the lining inspection opening.

3. The brake dust particle filter according to claim 2 , further comprising
a filter medium arranged on the filter medium support.

4. The brake dust particle filter according to claim 3 , wherein
the filter medium is at least at some locations thereof connected to the filter medium support.

5. The brake dust particle filter according to claim 4 , wherein
the filter medium is welded to the filter medium support.

6. The brake dust particle filter according to claim 3 , wherein
the filter medium is arranged radially inwardly in relation to the filter medium support in the mounted state of the brake dust particle filter.

7. The brake dust particle filter according to claim 1 , wherein
the brake dust particle filter comprises
a filter medium closing the lining inspection opening at least partially with precise fit in the mounted state of the brake dust particle filter.

8. The brake dust particle filter according to claim 7 , wherein
the filter medium comprises or is comprised of
a heat-resisting material.

9. The brake dust particle filter according to claim 8 , wherein
the heat-resisting material is selected from the group consisting of a metal, a metal fiber nonwoven, glass, ceramic, a high temperature resistant plastic material, and combinations thereof.

10. The brake dust particle filter according to claim 2 , wherein
the filter medium support comprises
at least one stop configured to be supported in the mounted state of the brake dust particle filter at the brake caliper.

11. The brake dust particle filter according to claim 10 , wherein
the at least one stop is configured to be supported at a rim region of the lining inspection opening.

12. The brake dust particle filter according to claim 10 , wherein
the at least one stop is a radial stop formed as a tongue.

13. The brake dust particle filter according to claim 2 , wherein
the filter medium support comprises
at least one clamping hook configured to hold the filter medium support in the lining inspection opening in the mounted state of the brake dust particle filter.

14. The brake dust particle filter according to claim 13 , wherein
the at least one clamping hook comprises
a radial extension matched to a material thickness of the brake caliper in a rim region surrounding the lining inspection opening so that the at least one clamping hook engages from behind the lining inspection opening in the mounted state of the brake dust particle filter.

15. The brake dust particle filter according to claim 1 , wherein
the brake dust particle filter is configured at least in sections thereof to be flowed through by a fluid.

16. The brake dust particle filter according to claim 1 , wherein
the brake dust particle filter in the mounted state thereof closes at least 60% of the lining inspection opening.

17. The brake dust particle filter according to claim 1 , wherein
the brake dust particle filter is configured to be inserted at least with sections thereof into the lining inspection opening.

18. The brake dust particle filter according to claim 2 , wherein
the filter medium support comprises
a plurality of through openings configured to be flowed through by the fluid.

19. A brake caliper for a disc brake assembly, the brake caliper comprising:
at least one caliper bridge extending in an axial direction of the brake caliper;
wherein the brake caliper further comprises a lining inspection opening arranged in the at least one caliper bridge;
a brake dust particle filter arranged in the lining inspection opening and closing the lining inspection opening at least partially with precise fit,
wherein the brake dust particle filter is connected to a brake caliper body of the brake caliper by a pivotable connection assembly.

20. The brake caliper according to claim 19 , wherein
the pivotable connection assembly comprises
at least one hinge.

21. The brake caliper according to claim 19 , wherein
the brake dust particle filter is connected to the brake caliper body of the brake caliper in a rim region of the lining inspection opening.

22. A disk brake assembly comprising:
a brake disc;
a brake caliper comprising
at least one caliper bridge extending in an axial direction of the brake caliper across the brake disc,
wherein the brake caliper comprises
a lining inspection opening arranged in the at least one caliper bridge, and

wherein the brake caliper further comprises
a brake dust particle filter for the brake caliper of the disc brake assembly,
wherein the brake dust particle filter is arranged in the lining inspection opening and closing the lining inspection opening at least partially with precise fit,

the disk brake assembly further comprising
a splash guard cover covering at least partially the brake disc circumferentially,

wherein the brake dust particle filter of the brake caliper is fastened to the splash guard cover.

23. The disk brake assembly according to claim 22 , wherein
the brake dust particle filter of the brake caliper is formed integrally as one piece with the splash guard cover.

24. A brake dust particle filter for a brake caliper of a disc brake assembly, wherein
the brake caliper comprises
a lining inspection opening,

wherein the brake dust particle filter is configured to close in a mounted state thereof the lining inspection opening at least partially with precise fit,
wherein the brake dust particle filter comprises
a filter medium support configured to be flowed through by a fluid at least in sections thereof,
wherein the filter medium support is matched to a shape and dimensions of the lining inspection opening and is configured to be inserted into the lining inspection opening,

wherein the filter medium support comprises
at least one clamping hook configured to hold the filter medium support in the lining inspection opening in the mounted state of the brake dust particle filter,

wherein the at least one clamping hook comprises
a radial extension matched to a material thickness of the brake caliper in a rim region surrounding the lining inspection opening so that the at least one clamping hook engages from behind the lining inspection opening in the mounted state of the brake dust particle filter.
