DESCRIPTION OF PREFERRED EMBODIMENTS

[0031] In FIGS. 1 to 3, in a first embodiment variant a brake disc arrangement 1 is illustrated that is typically used in motor vehicles. The brake disc arrangement 1 is provided with a brake dust particle filter 2 that comprises a filter housing 3 which is placed onto a brake disc 4 of the brake disc arrangement 1. The filter housing 3 accommodates a filter medium body in which brake dust is collected which is produced by friction during a braking action.

[0032] The brake disc arrangement 1 comprises in addition to the brake disc 4 a brake caliper holder 5 and a brake caliper 6 that is a carrier of brake pads which contact the brake disc 4 during a braking action. The brake caliper 6 is floatingly supported at the brake caliper holder 5 which is, for example, arranged at a wheel support. The floating support of the brake caliper 6 enables a relative movement of the brake caliper 6 relative to the brake caliper holder 5 in axial direction, in relation to the longitudinal axis of the brake disc 4. The floating support of the brake caliper 6 is achieved by means of bearing bolts 7 which extend parallel to the longitudinal axis of the brake disc 4 and are received in correlated cutouts in the brake caliper holder 5. Distributed about the circumference, a total of two bearing bolts 7 are arranged at oppositely positioned ends of brake caliper holder 5 and brake caliper 6.

[0033] The brake dust particle filter 2 is held by the brake caliper 6. For this purpose, the filter housing 3 of the brake dust particle filter 2 is screw-connected to an adapter part 8 that is fastened at the brake caliper 6. The adapter part 8 is embodied in a ring segment shape and extends concentrically to the circumferential side of the brake disc 4 at a radial distance to the circumferential side. The adapter part 8 comprises a total of three screw sleeves 9 distributed across its length—in relation to the circumferential direction—into which screws 10 can be screwed which can be inserted through openings 11 in the curved outer wall of the filter housing 3. The curved outer wall of the filter housing 3 is positioned in the mounted state also concentrically to the outer contour of the brake disc 4 so that the curved adapter part 8 and the inner side of the outer wall of the filter housing at which the adapter part 8 is resting extend also concentrically to each other (FIG. 2), wherein the inner side of the outer wall is supported advantageously at the adapter part 8. By being screw-connected to the adapter part 8, the filter housing 3 is fixedly connected to the brake caliper 6 so that, due to the floating support of the brake caliper 6 at the brake caliper holder 5, the brake dust particle filter 2 also carries out the floating movement of the brake caliper 6.

[0034] The adapter part 8 extends in circumferential direction across the same length as the brake caliper 6. The adapter part 8 comprises at both circumferential ends a respective U-shaped connecting section with laterally folded-down legs into which a bearing eye is introduced, respectively, through which the bearing bolt 7 is passed. The bearing bolt 7 at one end can be provided with a head wherein at the other end a securing element is arranged at the bearing bolt 7 in order to secure the bearing bolt 7 in its position for securing and holding brake caliper 6 as well as adapter part 8 at the brake caliper holder 5.

[0035] The total of three screw sleeves 9 at the adapter part 8 are distributed across the length of the adapter part. The two outwardly positioned screw sleeves 9 are positioned at or adjacent to the U-shaped connecting section at the respective end face end of the adapter part 8. The third screw sleeve 9 is located at the center of the adapter part 8. Immediately below the central screw sleeve 9 a recess is introduced in the brake caliper 6, as can be taken from FIG. 2, that enables an unhindered screwing in of the screw 10 into the central screw sleeve 9, wherein the tip of the screw projects through the screw sleeve 9 and the adapter part 8. The screw sleeve 9 comprises a radial extension while the length axis of the bearing bolts 7 is parallel to the axis of rotation of the brake disc 4.

[0036] The filter housing 3 forms a segment-shaped hood that extends about 180° wherein two parallel sidewalls are arranged at the curved outer wall. As a whole, the filter housing 3 forms a semi-annular shape that is closed to the exterior and to the sides but is open inwardly in order to enable placement on the brake disc 4.

[0037] The filter housing 3 extends across a larger angle segment than the brake caliper 6 and engages completely across the brake caliper 6 in circumferential direction. As can be taken from FIG. 2, the filter housing 3 is arranged slightly pivoted by a small angle amount of 5° to 10° in relation to the symmetry axis of the brake caliper 6. Due to this asymmetric positioning of the filter housing 3 in relation to the brake caliper 6, the filter housing 3 extends with sections of different size to the left and to the right of the brake caliper 6. Advantageously, the larger section of the filter housing 3 is located at the brake caliper 6 at the downstream side in relation to the rotational direction of the brake disc 4.

[0038] In FIGS. 4 to 6, a further embodiment of a brake disc arrangement 1 with a brake dust particle filter 2 is illustrated. The basic configuration corresponds to that of the first embodiment according to FIGS. 1 to 3. In the second embodiment according to FIGS. 4 to 6, an adapter part for connection of the filter housing 3 to the brake disc arrangement 1 is eliminated, however. Instead, the connection of the filter housing 3 to the brake disc arrangement 1 is realized by clamping tongues 12 that form clamping elements and are arranged at the filter housing 3. The clamping tongues 12 are monolithically formed with the filter housing 3 and are produced in the ring-shaped section of the filter housing 3 by stamping. In this way, in the ring-shaped section of the filter housing 3, a stamped opening 13 is formed in which the clamping tongue 12 extends radially inwardly in the direction toward the bearing bolt 7 which is engaged about by a curved section of the clamping tongue 12. In this way, a form fit and friction connection can be produced.

[0039] The curved sections of the clamping tongues 12 are oriented away from each other. In the mounted state, each bearing bolt 7 is engaged about by the clamping tongues 12 in circumferential direction at the outwardly positioned side—viewed from a central position between the bearing bolts 7. In this way, a form fit securing of the filter housing 3 at the bearing bolts 7 is ensured in circumferential direction.
