DESCRIPTION OF PREFERRED EMBODIMENTS

[0033] In the Figures, a brake dust particle filter 1 is illustrated that is used for a brake disk arrangement 2 (FIGS. 1, 2) in particular in motor vehicles, in order to absorb brake dust which is produced during a braking event by friction. The brake disk arrangement comprises a brake disk 3 and a brake caliper 4 that is carrier of the brake dust particle filter 1.

[0034] The brake dust particle filter 1 comprises a circular segment- or ring segment-shaped filter housing 5 that comprises a U-shaped cross section shape and receives a filter element or filter medium in which the brake dust is collected. The filter element can also have a U-shaped cross section shape corresponding to the filter housing 5. The filter housing 5 extends across an angle segment of approximately 180°.

[0035] The filter housing 5 is comprised of two housing side walls 6 and 7 which form the legs of the U-shape and are arranged spaced apart from each other and parallel. The filter housing 5 comprises moreover a housing circumferential wall 8 which forms the bottom of the U-shape and is of a curved configuration. The inner side of the housing circumferential wall 8 is positioned concentrically and equidistantly to the radial outer edge of the brake disk 3. The housing side walls 6, 7 and the housing circumferential wall 8 can form a one-piece component, wherein optionally also a multi-part filter housing is conceivable in which the housing side walls and the housing circumferential wall 8 are fixedly connected to each other.

[0036] The open radially inwardly oriented U-side in the filter housing 5 forms an opening 9 through which the brake disk 3 projects into the interior of the filter housing 5. Between the lateral surfaces and the radial outer edge of the brake disk 3 and the housing side walls 6, 7 as well as the housing circumferential wall 8, there is a respective gap that ensures a free and unhindered rotation of the brake disk 3 through the brake dust particle filter 1.

[0037] In order to ensure that the gap occupies only a defined maximum size, even when the brake disk becomes more narrow due to abrasion or differently sized or thick brake disks are installed, a delimitation part 10, 11, 12 is provided at the end face edge of both housing side walls 6, 7 and of the housing circumferential wall 8, respectively. Each delimitation part 10, 11, 12 is configured as a sheet metal part and can be screwed onto the respective end face edge of the housing side wall 6, 7 or of the housing circumferential wall 8. This makes it possible to fasten each delimitation part 10, 11, 12 detachably and thus exchangeably at the filter housing 5. Delimitation parts 10, 11, 12 can be used that are adapted to the respective brake disk 3 so that a desired gap width between the brake disk 3 and the filter housing 5 is achieved.

[0038] The delimitation parts 10, 11, 12 are arranged at the exit side—in relation to the rotational direction of the brake disk 3—of the filter housing 5. The two delimitation parts 10, 11 at the end face edge of the housing side walls 6, 7 are each formed in an arc shape and are positioned at the radially inwardly positioned end face edge of the housing side wall. The delimitation parts 10, 11 extend in the direction of the respective oppositely positioned housing side wall 6 or 7, wherein the opening 9 is formed between axially oppositely positioned inner edges of the delimitation parts 10, 11.

[0039] The delimitation part 12 is located at the circumferentially oriented end face edge of the housing circumferential wall 8 and comprises additional legs which simulate the U-shaped cross section shape of the filter housing 5 wherein each leg of the delimitation part 12 also contacts the circumferentially oriented end face edge of the housing side wall 6 and 7. The U-shaped delimitation part 12 is in itself of a planar configuration. The legs of the delimitation part 12 are embodied with different length. The delimitation part 12 forms essentially a delimitation wall of the filter housing in circumferential direction and extends advantageously substantially radially.

[0040] The two arc-shaped delimitation parts 10, 11 at the housing side walls 6, 7 adjoin immediately the U-shaped delimitation part 12 at the circumferentially oriented end face edge of the housing circumferential wall 8. This ensures a constant gap width.

[0041] The delimitation parts 10, 11 each can comprise a greater width than the thickness of the respective housing wall 6, 7, 8. In particular, the width amounts to a multiple of the thickness of the respective housing wall 6, 7, 8, preferably the width is at least 5 times, more preferred at least 10 times, larger than the thickness of the respective housing wall 6, 7, 8. Correspondingly, the delimitation parts 10, 11, 12 project inwardly past the inwardly positioned side wall of the respective housing wall 6, 7, 8 and delimit in this way the opening 9 much more than would be the case without delimitation parts 10, 11, 12.

[0042] In FIG. 4, arrows 13, 14 are shown which indicate the extension of the opening 9 in the filter housing 5 in axial direction (arrow 13) or in circumferential direction (arrow 14). Depending on the size of the delimitation parts 10, 11, 12, the free cross section area of the opening 9 is affected by the delimitation parts 10, 11, 12. Correspondingly, the gap between the inner side of the delimitation parts 10, 11, 12 and the brake disk which projects into the opening 9 changes also.
