Abstract

A disc brake for vehicles, in particular for commercial vehicles, includes brake pads which are arranged on both sides of a brake disc, a brake application device for applying one of the brake pads and a brake caliper for transmitting the application force to the brake pad on the other side, that is to say on the reaction side, of the brake disc. The brake caliper of the disc brake has a caliper frame which is produced from a shaped hollow profile.

First claim

What is claimed is:

1. A disc brake having a brake disc and brake pads, the disc brake comprising:
a brake application device for applying one of the brake pads against the brake disc on an application side;
a brake caliper that transfers an application force applied by the brake application device to the one of the brake pads on the application side to another one of the brake pads on a reaction side of the brake disc, wherein
the caliper comprises a caliper frame made from a closed internal hollow profile.

2. The disc brake according to claim 1 , wherein the caliper frame comprises at least one tension strut.

3. The disc brake according to claim 2 , wherein the caliper frame comprises a caliper rear.

4. The disc brake according to claim 3 , wherein the caliper frame comprises at least one shoulder for fixing the caliper frame to a caliper housing.

5. The disc brake according to claim 4 , wherein the tension strut has a substantially oval cross-section with parallel side faces.

6. The disc brake according to claim 5 , wherein the caliper rear has a substantially D-shaped cross-section.

7. The disc brake according to claim 6 , wherein the shoulder has a substantially oval cross-section with parallel side faces.

8. The disc brake according to claim 7 , wherein the hollow profile of the caliper frame has a constant wall thickness.

9. The disc brake according to claim 1 , wherein the hollow profile of the caliper frame has a constant wall thickness.

10. The disc brake according to claim 8 , further comprising a material bond of the caliper frame to the caliper housing.

11. The disc brake according to claim 8 , wherein the caliper frame is fixed to the caliper housing via a form and/or force fit.

12. The disc brake according to claim 1 , wherein the disc brake is a commercial vehicle disc brake.

13. A caliper for a commercial vehicle disc brake having a brake disc and brake pads, the caliper comprising:
a caliper housing in which a brake application device is arrangeable for applying an application force to one of the brake pads on an application side of the brake disc;
a caliper frame configured to straddle the brake disc and transfer application force applied by the brake application device to the one of the brake pads on the application side to another one of the brake pads on a reaction side of the brake disc, the caliper frame being formed by at least two tension struts and a caliper rear, wherein
the caliper frame has a closed internal hollow profile.

14. The caliper according to claim 13 , wherein the tension struts have a substantially oval cross-section with parallel side faces and the caliper rear has a substantially D-shaped cross-section.

15. The caliper according to claim 14 , wherein the hollow profile of the caliper frame has a constant wall thickness.

16. A method of forming a caliper frame of a disc brake, the caliper frame having at least one tension strut and a caliper rear, the method comprising the acts of:
providing a hollow steel profile by which to form the caliper frame, wherein the hollow steel profile has a mass predistribution in a region that will form the caliper rear; and
forming the caliper frame comprising the at least one tension strut and caliper rear such that the hollow profile of the caliper frame has a constant wall thickness.

17. The method according to claim 16 , wherein the mass predistribution in the region of the caliper rear is provided by an upsetting process.

18. The method according to claim 17 , wherein the act of forming the caliper frame comprises a bending process.

19. The method according to claim 18 , wherein the bending process is a swivel bending process.

20. The method according to claim 17 , wherein the act of forming the caliper frame comprises an internal high-pressure forming process.
