Abstract

A disc brake assembly includes a brake clip having a U-shaped section, at least one retention tang, and an abutment leg. The U-shaped section has a base leg and opposing upper and lower legs extending from the base leg. The upper leg has an inner face facing the lower leg. The at least one tang extends away from the U-shaped section and inner face. The abutment leg extends from the lower leg and has a midpoint between a top edge and a bottom edge. The midpoint is not planar with the top and bottom edges.

First claim

What is claimed is:

1. A disc brake assembly comprising:
a brake clip having:
a U-shaped section having a base leg and opposing upper and lower legs extending from the base leg; and
a retraction spring having a first retraction spring portion being coplanar with the base leg and extending from the base leg, a second retraction spring portion extending from the first retraction spring portion, and a first position without loading, wherein:
the first and second retraction spring portions move from the first position to a second position when loaded to a threshold load, wherein when in the second position the first retraction spring portion and a transition portion of the second retraction spring portion are at a right angle to the base leg with the transition portion, the upper leg, and the lower leg extending to the same side of the base leg; and
the first retraction spring portion remains at the second position, and the second retraction spring portion moves beyond the second position, when loaded beyond the threshold load.

2. The disc brake assembly of claim 1 wherein the upper leg has an inner face facing the lower leg, and a retention tang extends from the U-shaped section and away from the inner face.

3. The disc brake assembly of claim 2 wherein the retention tang is fixed to the base leg.

4. The disc brake assembly of claim 2 further comprising:
an anchor bracket having a channel in which the brake clip is mounted; and
a groove in an upper surface of the channel, wherein the retention tang is engaged in the groove.

5. The disc brake assembly of claim 4 further comprising:
at least one brake pad supported on the anchor bracket; and
a brake caliper slidably supported on the anchor bracket.

6. The disc brake assembly of claim 1 further comprising:
a support leg extending from the upper leg and configured to generally correspond with and extend adjacent to a front surface of the anchor bracket when the brake clip is installed on the anchor bracket.

7. The disc brake assembly of claim 1 wherein the threshold load is configured to be calibrated by adjusting the material or cross-section of the first and second retraction spring portions.

8. The disc brake assembly of claim 1 wherein the first and second retraction spring portions are resilient portions.

9. A disc brake assembly comprising:
a brake clip having:
a U-shaped section having a base leg and opposing upper and lower legs extending from the base leg, wherein the upper leg has an inner face facing the lower leg and a retention tang extends from the U-shaped section and away from the inner face; and
a retraction spring having a first retraction spring portion being coplanar with the base leg and extending from the base leg, a second retraction spring portion extending from the first retraction spring portion, and a first position without loading, wherein:
the first and second retraction spring portions move from the first position to a second position when loaded to a threshold load, wherein when in the second position the first retraction spring portion and a transition portion of the second retraction spring portion are at an angle to the base leg with the transition portion, the upper leg, and the lower leg extending to the same side of the base leg; and
the first retraction spring portion remains at the second position, and the second retraction spring portion moves beyond the second position, when loaded beyond the threshold load;
wherein the threshold load is configured to be calibrated by adjusting the material or cross-section of the first and second retraction spring portions; and
wherein the first and second retraction spring portions are resilient portions.

10. The disc brake assembly of claim 9 wherein the upper leg has an inner face facing the lower leg, and a retention tang extends from the U-shaped section and away from the inner face.

11. The disc brake assembly of claim 10 wherein the retention tang is fixed to the base leg.

12. The disc brake assembly of claim 10 further comprising:
an anchor bracket having a channel in which the brake clip is mounted; and
a groove in an upper surface of the channel, wherein the retention tang is engaged in the groove.

13. The disc brake assembly of claim 12 further comprising:
at least one brake pad supported on the anchor bracket; and
a brake caliper slidably supported on the anchor bracket.

14. The disc brake assembly of claim 9 further comprising:
a support leg extending from the upper leg and configured to generally correspond with and extend adjacent to a front surface of the anchor bracket when the brake clip is installed on the anchor bracket.

15. The disc brake assembly of claim 9 wherein when in the second position the first retraction spring portion and the transition portion of the second retraction spring portion are at a right angle to the base leg.

16. A disc brake assembly comprising:
a brake clip having:
a U-shaped section having a base leg and opposing upper and lower legs extending from the base leg; and
a retraction spring having a first retraction spring portion being coplanar with the base leg and extending from the base leg, a second retraction spring portion extending from the first retraction spring portion, and a first position without loading, wherein:
the first and second retraction spring portions move from the first position to a second position when loaded to a threshold load, wherein when in the second position the first retraction spring portion and a transition portion of the second retraction spring portion are at an angle to the base leg with the transition portion, the upper leg, and the lower leg extending to the same side of the base leg; and
the first retraction spring portion remains at the second position, and the second retraction spring portion moves beyond the second position, when loaded beyond the threshold load, wherein the threshold load is configured to be calibrated by adjusting the material or cross-section of the first and second retraction spring portions.

17. The disc brake assembly of claim 16 further comprising:
an anchor bracket having a channel in which the brake clip is mounted; and
a groove in an upper surface of the channel, wherein the retention tang is engaged in the groove.
