Abstract

The invention relates to a brake dust collector (10) for a disc brake (12) comprising a brake disc (18) and a brake caliper (16) clasping the latter. The brake dust collector (10) includes a housing (24) designed to clasp a portion of the brake disc (18) directly adjoining the brake caliper (16) in the main direction of rotation (R) of the brake disc (18). Provided arranged in the housing (24) is a brake dust retainer comprising a plurality of brake dust intake ports. To ensure practically total retainment of the resulting brake dust without detrimenting, indeed, even improving the cooling of the disc brake (12) the housing (24) features a plurality of air intake ports (34; 38) separate from the inner brake dust intake ports, making it possible to direct the inflow of air in the direction of the brake disc (18) and into the inner brake dust intake ports.

Claims

1. A brake dust collector (10) for a disc brake (12) comprising a brake disc (18) and a brake caliper (16) clasping the latter, including a housing (24) designed to clasp a portion of the brake disc (18) directly adjoining the brake caliper (16) in the main direction of rotation (R) of the brake disc (18) and provided arranged in the housing (24) with a brake dust retainer comprising a plurality of brake dust intake ports, characterized in that the housing (24) features a plurality of air intake ports (34;

38) separate from the brake dust intake ports (48).

2. The brake dust collector as set forth in claim 1 characterized in that the housing (24) is provided on both sides of the brake disc (18) with at least one air intake port (34) arranged upstream of the brake dust intake ports (48) as viewed in the main direction of rotation (R) of the brake disc (18).

3. The brake dust collector as set forth in claim 1, characterized in that the housing (24) features at least one air intake port (38) radially external to the brake disc (18).

4. The brake dust collector as set forth in claim 1, characterized in that the housing (24) comprises air outlet ports (46) arranged separate from the air intake ports (34;

38).

5. The brake dust collector as set forth in claim 4, characterized in that the air outlet ports (46) feature filters which retain the brake dust but allow air and water to pass.

6. The brake dust collector as set forth in claim 1, characterized in that the brake dust retainer features on both sides of the brake disc (18) at least one slat (42, 42′

) extended radially relative to the brake disc (18) and along the circuference of the brake disc (18), beginning at a brake dust intake port (48) and ending in the brake dust collection chamber (44).

7. The brake dust collector as set forth in claim 6, characterized in that a plurality of slats (42) is provided, each extending from an assigned brake dust intake port (48) into the brake dust collection chamber (44), defining between each other passageways (50) for directing the brake dust into the brake dust collection chamber (44).

8. The brake dust collector as set forth in claim 6, characterized in that the cross-section of the one or each brake dust intake port (48) is greater than the porting criss section at the end of each slat (42, 42′

).

9. The brake dust collector as set forth in claim 6, characterized in that each slat (42′

) extends along the the circuference of the brake disc (18) firstly in the main direction of rotation (R), before extending radially inwards and finally contrary to the main direction of rotation (R).

10. The brake dust collector as set forth in claim 1, characterized in that the housing (24) is configured split to comprise a first housing part (26) for mounting the brake dust collector on the disc brake (12), as well as a second housing part (32) releasably secured to the first housing part (26).

11. The brake dust collector as set forth in claim 10, characterized in that the housing (24) is provided on both sides of the brake disc (18) with at least one air intake port (34) arranged upstream of the brake dust intake ports (48) as viewed in the main direction of rotation (R) of the brake disc (18) and in that the air intake ports (34) arranged on both sides of the brake disc (18) are configured on the first housing part (26).

12. The brake dust collector as set forth in claim 10, characterized in that the brake dust retainer features on both sides of the brake disc (18) at least one slat (42, 42′

) extended radially relative to the brake disc (18) and along the circuference of the brake disc (18), beginning at a brake dust intake port (48) and ending in the brake dust collection chamber (44) and in that the brake dust collection chamber (44) is provided in the second housing part (32).

13. The brake dust collector as set forth in claim 6, characterized in that a level sensor monitors the amount of brake dust in the brake dust collection chamber (44).

14. The brake dust collector as set forth in claim 13, characterized in that the level sensor is an optical sensor.

15. The brake dust collector as set forth in claim 6, characterized in that the brake dust collection chamber (44) comprises a dump valve.

16. The brake dust collector as set forth claim 1, characterized in that provided on both sides of the brake disc (18) upstream of the brake dust intake ports (48) is at least one wiper (4) designed to come into contact with the corresponding sides of the brake disc (18).

17. The brake dust collector as set forth in claim 16, characterized in that the wipers (40) are mounted movable axially and come into contact axially with the brake disc (18) when the disc brake (12) is activated.

18. The brake dust collector as set forth in claim 17, characterized in that the wipers (40) are moved to the brake disc (18) hydraulically.

19. A disc brake (12), characterized by a brake dust collector (10) as set forth in claim 1.
