Abstract

A resetting device by which a brake caliper can be reset after a braking-induced displacement and release of a brake. The resetting device has a spreading device which has resilient spreading elements. The spreading device is arranged in a central opening of the brake caliper. The spreading elements engage, outside the friction pads, directly or indirectly on one side at at least two abutment regions arranged spaced apart from one another relative to the center, of the brake pads, where the abutment regions have one abutment surface and one bearing surface on which the spreading elements are movably arranged. The spreading device has spring arms, of which in each case two lie against an associated pad carrier plate, where the spring arms are connected to one another in the central region of the opening. The spring arms are connected to a retaining bow which is attached to a brake carrier.

First claim

What is claimed is:

1. A resetting device for a disc brake of a commercial vehicle, comprising:
a spreading device which is engageable on opposite brake pads of the disc brake and which has resilient spreading elements which are engageable on respective pad carrier plates of the disc brake;
wherein the spreading device is arrangeable in a central opening of a brake caliper of the brake disc;
wherein the spreading device has spring arms;
wherein the spring arms are connected to a retaining bow which is attachable to a brake carrier of the disc brake;
and wherein each spring arm is formed, at an end, with a fork-shaped spring end such that a support limb and a thrust-imparting limb are formed.

2. The resetting device as claimed in claim 1 , wherein the retaining bow is attachable to two mutually oppositely situated stirrups which are connected to the brake carrier.

3. The resetting device as claimed in claim 1 , wherein the retaining bow is of C-shaped form with two mutually oppositely situated end limbs and with a center limb.

4. The resetting device as claimed in claim 3 , wherein the end limbs have in each case one lug into which pegs of the brake carrier horns are insertable.

5. The resetting device as claimed in claim 1 , wherein the spring arms and/or the retaining bow are/is supportable in a radial direction on the brake carrier.

6. A resetting device for a disc brake of a commercial vehicle, comprising:
a spreading device which is engageable on opposite brake pads of the disc brake and which has resilient spreading elements which are engageable on respective pad carrier plates of the disc brake;
wherein the spreading device is arrangeable in a central opening of a brake caliper of the brake disc;
wherein the spreading device has spring arms;
wherein the spring arms are connected to a retaining bow which is attachable to a brake carrier of the disc brake;
and wherein each spring arm is formed, at an end, with a spring end with a fastening section which, in its longitudinal direction, is formed with an elongated hole which is a guide section for the spring end of the spreading device.

7. The resetting device as claimed in claim 6 , wherein the retaining bow is attachable to two mutually oppositely situated stirrups which are connected to the brake carrier.

8. The resetting device as claimed in claim 6 , wherein the retaining bow is of C-shaped form with two mutually oppositely situated end limbs and with a center limb.

9. The resetting device as claimed in claim 8 , wherein the end limbs have in each case one lug into which pegs of the brake carrier horns are insertable.

10. The resetting device as claimed in claim 6 , wherein the spring arms and/or the retaining bow are/is supportable in a radial direction on the brake carrier.
