Abstract
A backing plate and associated brake pad that includes a reinforcement plate and a retention plate. The reinforcement plate has an outboard surface, an inboard surface, and a mold hole. The retention plate has an outboard surface, an inboard surface, and a locking projection that cooperates with the mold hole of the reinforcement plate to mechanically lock the retention plate to the reinforcement plate so that the inboard surface of the reinforcement plate faces the outboard surface of the retention plate. A dampening layer may be included between the reinforcement plate and the retention plate.
Claims13
A backing plate for a brake pad, comprising:
- a reinforcement plate having an outboard surface, an inboard surface, and a mold hole;
- a retention plate having an outboard surface, an inboard surface, and a locking projection that cooperates with the mold hole of the reinforcement plate to mechanically lock the retention plate to the reinforcement plate so that the inboard surface of the reinforcement plate faces the outboard surface of the retention plate, wherein the mold hole is configured to retain at least a portion of friction pad material from a friction pad, wherein the locking projection is a hollow boss comprising an annular interface wall having an outer surface and an inner surface;
- and
- a dampening layer between the reinforcement plate and the retention plate, wherein an annular portion of the dampening layer is located adjacent to the outer surface of the annular interface wall of the locking projection.

A brake pad, comprising:
- a backing plate and a friction pad, the backing plate comprising:
- a reinforcement plate having an outboard surface, an inboard surface, and a mold hole;
- and
- a retention plate having an outboard surface, an inboard surface, and a locking projection that cooperates with the reinforcement plate to mechanically lock the retention plate to the reinforcement plate so that the inboard surface of the reinforcement plate faces the outboard surface of the retention plate, wherein the retention plate includes a plurality of retention members configured to interlock a the friction pad, wherein the plurality of retention members project from the inboard surface of the retention plate to interlock the friction pad, and wherein the plurality of retention members is located on the inboard surface of the retention plate separate from the locking projection and the mold hole;
- and
- wherein the friction pad is comprised of a friction material and the friction pad has a friction surface and an attachment surface, wherein the attachment surface is attached to the inboard surface of the retention plate, wherein the friction material at the attachment surface extends at least partially into the mold hole, and wherein the retention plate is located between the friction pad and the reinforcement plate such that the inboard surface of the retention plate faces against the attachment surface of the friction pad and the outboard surface of the retention plate faces against the inboard surface of the reinforcement plate.

A brake pad, comprising:
- a backing plate and a friction pad, the backing plate comprising:
- a reinforcement plate having an outboard facing surface, an inboard surface, and a mold hole;
- and
- a retention plate having an outboard surface, an inboard surface, and a locking projection that cooperates with the mold hole of the reinforcement plate to mechanically lock the retention plate to the reinforcement plate so that the inboard surface of the reinforcement plate faces the outboard surface of the retention plate, wherein the locking projection includes a flanged edge which rests against the outboard facing surface of the reinforcement plate, wherein the mold hole is configured to retain at least a portion of friction pad material from a friction pad, and wherein the reinforcement plate is thicker than the retention plate;
- and
- wherein the friction pad is comprised of a friction material and the friction pad has a friction surface and an attachment surface, wherein the attachment surface is attached to the inboard surface of the retention plate, wherein the friction material at the attachment surface extends at least partially into the mold hole, and wherein the retention plate is located between the friction pad and the reinforcement plate such that the inboard surface of the retention plate faces against the attachment surface of the friction pad and the outboard surface of the retention plate faces against the inboard surface of the reinforcement plate.
