Methods for making a brake pad retention plate
A method of making a brake pad retention plate and a brake pad retention plate is provided. The method includes upsetting a brake pad facing surface on the retention plate to form a first set of rows having a gutter, or a negative feature such as a depression in the primary plane, in the surface of the retention plate and a tooth feature on a first side of the gutter. The surface of the retention plate is upset to form a second set of rows having a gutter and a tooth feature on the second side of the gutter. The second set of rows being a single row. The second set of rows is placed adjacent to or between the first set of rows. A mechanical press is used to deform the tooth to form a base portion and a mezzanine portion extending over a portion of the gutter.
1. A method of making at least one retention feature on a surface of a brake pad retention plate, comprising the steps of:
upsetting a portion of the surface to form at least one gutter and at least one tooth feature; and
bending the at least one tooth feature to form a base portion extending vertically from the surface and a mezzanine portion extending horizontally above the at least one gutter.
2. The method according to claim 1 , wherein the step of bending the at least one tooth feature comprises compressing the at least one tooth feature with a press, wherein the at least one tooth feature bends at an inflection point to form the base portion and the mezzanine portion, such that a capture chamber is formed between the mezzanine portion and the at least one gutter.
3. The method according to claim 2 , wherein the capture chamber has an opening configured to allow material to enter the capture chamber.
4. The method according to claim 1 , wherein the mezzanine portion is formed proximate to a longitudinal center line of the at least one gutter.
5. The method according to claim 1 , wherein the mezzanine portion has a length of no more than about 3 mm.
6. The method according to claim 1 , wherein the mezzanine portion has a length between 1.5 and 2.5 mm.
7. The method according to claim 1 , wherein the mezzanine portion has a length of approximately ⅓ of the length of the at least one gutter.
8. The method according to claim 1 , wherein the mezzanine portion has a length of approximately ¼ of the length of the at least one gutter.
9. The method according to claim 8 , wherein the angle is between 45 and 90 degrees.
10. The method according to claim 1 , wherein the at least one tooth feature has a substantially straight gutter facing surface that forms an angle with a floor of the at least one gutter.
11. A brake pad retention plate, comprising
a brake pad facing surface;
at least one gutter disposed on the brake pad facing surface; and
at least one tooth feature having a base portion extending vertically from the brake pad facing surface and a mezzanine portion extending horizontally above the at least one gutter.
12. The brake pad retention plate according to claim 11 , wherein the base portion and the mezzanine portion are separated by a bend in the at least one tooth feature.
13. The brake pad retention plate according to claim 11 , wherein a capture chamber is disposed between the mezzanine portion and the at least one gutter.
14. The brake pad retention plate according to claim 13 , wherein the capture chamber has an opening configured to allow material to enter the capture chamber.
15. The brake pad retention plate according to claim 11 , wherein the mezzanine portion is formed proximate to a longitudinal center line of the at least one gutter.
16. The brake pad retention plate according to claim 11 , wherein the mezzanine portion has a length between 1.5 and 2.5 mm.
17. The brake pad retention plate according to claim 11 , wherein the mezzanine portion has a length of approximately ⅓ of the length of the at least one gutter.
18. The brake pad retention plate according to claim 11 , wherein the mezzanine portion has a length of approximately ¼ of the length of the at least one gutter.
19. The brake pad retention plate according to claim 11 , wherein the at least one tooth feature has a substantially straight gutter facing surface that forms an angle with a floor of the at least one gutter.
20. The brake pad retention plate according to claim 19 , wherein the angle is between 45 and 90 degrees.
