Abstract

A brake dust particle filter for a disc brake assembly with brake disc and brake caliper has a ring segment-shaped housing accommodating the brake disc in the interior. The housing has first and second axially spaced apart housing sidewalls and a housing peripheral wall extending radially outwardly in circumferential direction and arranged between the first and second housing sidewalls. A first housing part includes the first and/or second housing sidewall such that the first and/or second housing sidewall is positionable axially displaced to the brake disc. A second housing part includes at least the housing peripheral wall. First and second housing parts are connected by a pivot mechanism having a pivot axis extending parallel to an axis of rotation of the brake disc. Due to the pivot mechanism, the housing peripheral wall is pivotable relative to the first housing part while the first and/or second housing sidewall remains stationary.

First claim

What is claimed is:

1. A brake dust particle filter for a disc brake assembly with a brake disc and a brake caliper, wherein the brake dust particle filter is configured for catching particles produced when braking, the brake dust particle filter comprising:
a ring segment-shaped housing comprising a housing interior and configured to accommodate, in a mounted state thereof, at least partially the brake disc in the housing interior;
wherein the ring segment-shaped housing comprises housing walls, including a first housing sidewall and a second housing sidewall axially spaced apart from each other,
wherein the housing walls further include a housing peripheral wall extending radially outwardly in a circumferential direction of the ring segment-shaped housing and arranged between the first and second housing sidewalls in the mounted state;
wherein the ring segment-shaped housing comprises a first housing part comprising the first housing sidewall and/or the second housing sidewall and configured such that the first housing sidewall and/or the second housing sidewall are positionable axially displaced relative to the brake disc;
wherein the ring segment-shaped housing comprises a second housing part comprising at least the housing peripheral wall;
wherein the first housing part and the second housing part are connected to each other by a pivot mechanism comprising a pivot axis extending parallel to an axis of rotation of the brake disc in the mounted state and configured such that the housing peripheral wall is pivotable relative to the first housing part with the first housing sidewall and/or the second housing sidewall remaining stationary.

2. The brake dust particle filter according to claim 1 , wherein
the pivot axis is arranged at an end of the ring segment-shaped housing that, in the mounted state, faces the brake caliper such that the pivot mechanism is openable opposite to a predefined forward travel rotational direction of the disc brake assembly.

3. The brake dust particle filter according to claim 1 , wherein
the first housing part and the second housing part are connected to each other so as to be reversibly detachable.

4. The brake dust particle filter according to claim 1 , wherein
the housing peripheral wall is embodied at the first housing sidewall and/or at the second housing sidewall.

5. The brake dust particle filter according to claim 1 , wherein
the housing peripheral wall is embodied of the first and second housing parts that at least partially overlap each other.

6. The brake dust particle filter according to claim 1 , wherein
the first housing part and/or the second housing part is embodied as a splash guard.

7. The brake dust particle filter according to claim 6 , wherein
the splash guard is a splash guard plate.

8. The brake dust particle filter according to claim 1 , wherein
the first housing part is connected to the second housing part by a releasable connecting arrangement.

9. The brake dust particle filter according to claim 8 , wherein
the releasable connecting arrangement connects the first housing part and the second housing part in an end position of the pivot mechanism.

10. The brake dust particle filter according to claim 9 , wherein
the releasable connecting arrangement is a screw connection or a clip connection.

11. The brake dust particle filter according to claim 1 , further comprising
at least one tongue arranged at the ring segment-shaped housing and projecting at least with sections thereof inwardly into the housing interior and
further comprising at least one filter medium,
wherein the at least one tongue supports the at least one filter medium and is covered at least partially with the filter medium.

12. The brake dust particle filter according to claim 11 , wherein
the at least one tongue is arranged at one of the housing sidewalls so that the at least one filter medium is connected indirectly or directly to said one housing wall.

13. The brake dust particle filter according to claim 11 , wherein
the at least one tongue is arranged at the housing peripheral wall so that the at least one filter medium is connected indirectly or directly to the housing peripheral wall.

14. The brake dust particle filter according to claim 11 , further comprising
a filter element with a filter element support structure,
wherein the filter element includes the least one filter medium,
wherein the filter element support structure includes the at least one tongue, and
wherein the filter element is arranged in the ring segment-shaped housing.

15. The brake dust particle filter according to claim 14 , wherein
the filter element is reversibly exchangeably arranged in the ring segment-shaped housing.

16. The brake dust particle filter according to claim 11 , wherein
the at least one filter medium is fastened to one or more elements selected from the group consisting of the at least one tongue; the housing walls; and the filter element support structure.

17. The brake dust particle filter according to claim 11 , wherein
the at least one filter medium forms a fold into which the at least one tongue projects at least partially.

18. The brake dust particle filter according to claim 11 , wherein
the at least one tongue comprises one or more through openings covered by the at least one filter medium.

19. The brake dust particle filter according to claim 1 , wherein
one of the housing walls comprises one or more openings for discharge of filtered air.

20. The brake dust particle filter according to claim 1 , wherein
the housing peripheral wall comprises one or more openings for discharge of filtered air.

21. A disc brake assembly comprising the brake disc, the brake caliper, and the brake dust particle filter according to claim 1 .

22. A disc brake assembly according to claim 21 , wherein
the brake dust particle filter is arranged stationarily relative to the brake caliper or is fastened to the brake caliper.

23. The disc brake assembly according to claim 21 , further comprising
a wheel bearing housing,
wherein the brake dust particle filter is stationarily arranged relative to the wheel bearing housing or is fastened to the wheel bearing housing.

24. The disc brake assembly according to claim 21 , further comprising
a splash guard,
wherein the brake dust particle filter is stationarily arranged relative to the splash guard; is fastened to the splash guard; or the first housing part of the ring segment-shaped housing forms the splash guard.

25. The disc brake assembly according to claim 24 , wherein
the splash guard is a splash guard plate.
