Abstract

A brake lining restoring device includes at least one clamping limb with at least one first aperture, at least one base limb, and at least one clamping limb. The clamping limb and the one base limb may be connected to one another via at least one spring section. The clamping limb may be moved under elastic deformation relative to the at least one base limb. The brake lining restoring device may include a frictionally locking connection to a holding element which is assigned to the brake lining arrangement can be established via one edge (R) of the first aperture of the clamping limb.

First claim

What is claimed is:

1. A brake lining restoring device for a brake lining arrangement of a vehicle disk brake, having:
at least one clamping limb with at least one first aperture,
at least one base limb,
the at least one clamping limb and the at least one base limb being connected to one another via at least one spring section, it being possible for the at least one clamping limb to be moved under elastic deformation relative to the at least one base limb,
the brake lining restoring device being configured in such a way that a frictionally locking connection to a holding element which is assigned to the brake lining arrangement can be established via one edge (R) of the first aperture of the at least one clamping limb,
the brake lining restoring device being configured, furthermore, in such a way that the frictionally locking connection can be released by way of a relative movement of the at least one clamping limb in the direction of the at least one base limb, which relative movement exceeds a predefined travel.

2. The brake lining restoring device as defined in claim 1 , the at least one base limb having at least one second aperture.

3. The brake lining restoring device as defined in claim 2 , it being possible for the at least one spring section to be deformed elastically in such a way that the first aperture and the second aperture can be penetrated by the at least one holding element.

4. The brake lining restoring device as defined in claim 1 , the at least one spring section providing a prestress which presses the edge (R) of the first aperture against the holding element.

5. The brake lining restoring device as defined in claim 1 , the clamping limb and the base limb extending at a predefined angle (α) with respect to one another.

6. The brake lining restoring device as defined in claim 1 , the at least one clamping limb having a fastening section which has a first fastening opening.

7. The brake lining restoring device as defined in claim 6 , the at least one base limb having at least one second fastening opening.

8. The brake lining restoring device as defined in claim 6 , it being possible for the fastening section of the clamping limb to be brought into contact with the base limb.

9. The brake lining restoring device as defined in claim 8 , the predefined angle (α) being set when the fastening section of the clamping limb is in contact with the base limb.

10. The brake lining restoring device as defined in claim 1 , the brake lining restoring device having at least one positioning section which serves to position the brake lining restoring device on a brake lining arrangement.

11. The brake lining restoring device as defined in claim 1 , the base limb having at least one supporting element.

12. The brake lining restoring device as defined in claim 1 , the brake lining restoring device having a brake lining guide element which is connected to the base limb.

13. The braking lining arrangement as defined in claim 1 , the relative movement being in a brake apply direction and the edge being configured to have a first action point engaging the holding element prior to the relative movement exceeding the predefined travel, the edge having a second action point different from the first action point and configured to engage the holding element after the relative movement exceeds the predefined travel.

14. A brake lining arrangement for a vehicle disk brake, having:
a brake lining carrier plate;
at least one friction lining which is attached to the brake lining carrier plate; and
a brake lining restoring device further comprising,
at least one clamping limb with at least one first aperture,
at least one base limb,
the at least one clamping limb and the at least one base limb being connected to one another via at least one spring section, it being possible for the at least one clamping limb to be moved under elastic deformation relative to the at least one base limb,
the brake lining restoring device being configured in such a way that a frictionally locking connection to a holding element which is assigned to the brake lining arrangement can be established via one edge (R) of the first aperture of the at least one clamping limb,
the brake lining restoring device being configured, furthermore, in such a way that the frictionally locking connection can be released by way of a relative movement of the at least one clamping limb in the direction of the at least one base limb, which relative movement exceeds a predefined travel.

15. The brake lining arrangement as defined in claim 14 , at least one fastening projection being configured on the front side of the brake lining carrier plate, to which fastening projection the at least one brake lining restoring device can be fastened.

16. The braking lining arrangement as defined in claim 14 , the relative movement being in a brake apply direction and the edge having a first action point engaging the holding element prior to the relative movement exceeding the predefined travel, the edge having a second action point different from the first action point and engaging the holding element after the relative movement exceeds the predefined travel.

17. A brake lining restoring device for a brake lining arrangement of a vehicle disk brake, having:
a base limb;
a clamping limb with an aperture defined by an edge; and
a spring section connecting the clamping limb to the base limb such that the clamping limb is elastically deformable relative to the base limb, wherein the edge is configured to form a frictionally locking connection with a holding element assigned to the brake lining arrangement, the frictionally locking connection being releasable in response to relative movement between the clamping limb and the base limb exceeding a predefined travel in a brake apply direction such that the edge is configured to have a first action point engaging the holding element prior to the relative movement exceeding the predefined travel, the edge having a second action point different from the first action point and configured to engage the holding element after the relative movement exceeds the predefined travel.
