Abstract

A disc brake including a brake caliper, which includes two lateral wings which tangentially encompass at least one brake disc, and which is displaceably guided on a brake carrier by two guiding elements, which are arranged opposite with respect to each other and radially with respect to the axis of the brake disc between the brake caliper and the brake carrier, in which a first guiding element in the area of one wing consists of a combination of a sliding bore and a guide pin being guided within it, and in which a second guiding element is configured within the opposite wing as a combination of at least two cooperating guiding surfaces.

First claim

The invention claimed is:

1. A disc brake including a brake caliper, said brake caliper comprising:
first and second lateral wings tangentially encompassing at least one brake disc, said brake caliper being displaceably guided on a brake carrier by means of two guiding elements that are arranged opposite with respect to each other and radially with respect to an axis of the at least one brake disc between the brake caliper and the brake carrier,
a first guiding element in an area of the first lateral wing, the first guiding element including a sliding bore and a guide pin being guided within the sliding bore, and
a second guiding element is configured within the second lateral wing, the second guiding element including at least two cooperating guiding surfaces at least one of said guiding surfaces being integral with the second lateral wing or made as a separate component to be fixed to the second lateral wing,
said brake carrier comprises at least one guiding section having at least one guiding surface, which is guided by at least one corresponding guiding surface of the second lateral wing, thereby forming a second guiding element.

2. The disc brake according to claim 1 , in which the second guiding element in axial direction is arranged substantially in proximity to a center of the second lateral wing.

3. The disc brake according to claim 2 , in which the second guiding element is arranged radially above the at least one brake disc.

4. The disc brake according to claim 1 , in which the guiding elements are arranged radially and externally of a braking surface of the at least one brake disc.

5. The disc brake according to claim 1 , in which the brake carrier comprises two guiding sections having guiding surfaces, which are guided at guiding surfaces being arranged on the edges of the second lateral wing.

6. The disc brake according to claim 5 , in which a guiding section of the brake carrier comprises a guiding surface and opposite thereto a guiding surface for guidance of a brake pad holder.

7. The disc brake according to claim 1 , in which the second lateral wing comprises a recess, in which a guiding section of the brake carrier is guided in a sliding manner.

8. The disc brake according to claim 7 , in which at least one spring element is arranged between the guiding surfaces of the brake carrier and of the second lateral wing, which spring element extends axially over the length of the recess.

9. The disc brake according to claim 8 , in which the spring element is guided in the recess in a displaceable manner.

10. The disc brake according to claim 1 , in which at least one spring element is arranged between the guiding surfaces of the brake carrier and the second lateral wing.

11. The disc brake according to claim 10 , in which the spring element can be compressed thereby generating a return force.

12. The disc brake according to claim 1 , in which the guiding surfaces of the brake carrier and/or of the wings are provided with a friction-reducing and/or wear-resistant coating.

13. A disc brake having a brake caliper, said brake caliper comprising:
a first lateral wing,
a second lateral wing,
at least one brake disc, wherein said first and second lateral wings tangentially encompass said at least one brake disc,
wherein said brake caliper is displaceably guided on a brake carrier by means of two guiding elements that are arranged opposite with respect to each other and radially with respect to an axis of said at least one brake disc between the brake caliper and the brake carrier,
a first guiding element positioned in adjacent to the first lateral wing, said first guiding element having a sliding bore and a guide pin that is guided within the sliding bore, and
at least one guiding section having at least one guiding surface that is guided by at least one corresponding guiding surface of said second lateral wing, thereby forming a second guiding element, wherein at least one of said guiding surfaces being integral with said second lateral wing or made as a separate component to be fixed to said second lateral wing.

14. The disc brake according to claim 13 , in which the second guiding element in axial direction is arranged substantially in proximity to a center of the second lateral wing.

15. The disc brake according to claim 14 , in which the second guiding element is arranged radially above the at least one brake disc.

16. The disc brake according to claim 13 , in which the guiding elements are arranged radially and externally of a braking surface of the at least one brake disc.

17. The disc brake according to claim 13 , in which the brake carrier comprises two guiding sections having guiding surfaces, which are guided at guiding surfaces being arranged on the edges of the second lateral wing.

18. The disc brake according to claim 17 , in which a guiding section of the brake carrier comprises a guiding surface and opposite thereto a guiding surface for guidance of a brake pad holder.

19. The disc brake according to claim 13 , in which at least one spring element is arranged between the guiding surfaces of the brake carrier and the second lateral wing.

20. The disc brake according to claim 13 , in which the guiding surfaces of the brake carrier and/or of the wings are provided with a friction-reducing and/or wear-resistant coating.
