Abstract
The invention is a plate for holding a friction material in a brake assembly. The plate preferably comprises a contact surface for attaching the friction material to the plate, a second surface opposing the contact surface; and a plurality of retaining structures formed on the contact surface, each retaining structure comprising a projecting member extending from a point between the contact surface and the second surface, so that the member extends outwardly from the contact surface for engagement with the friction material.
Claims24
A method of manufacturing a brake backing plate for securing a friction material to a contact surface thereof, the plate comprising a contact surface for attaching the friction material to the plate, the method comprising:
- positioning a cutting apparatus adjacent a contact surface of the plate, wherein the cutting apparatus includes at least one knife with at least one tooth, the at least one tooth including a single leading surface at least a portion of which is formed in a sideward plow angle shape;
- and
- forming a plurality of parallel rows of integral retaining structures on the contact surface, each retaining structure comprising:
- (a) a projecting member extending outwardly from the contact surface for engagement with the friction material and having a shaped configuration resulting from the sideward plow angle of the at least one tooth;
- and
- (b) a depression surface abutting the projecting member, the depression surface extending into the contact surface without perforating the contact surface.
A method of manufacturing a brake backing plate for securing a friction material thereto, the method comprising:
- positioning a cutting apparatus adjacent a contact surface of the plate, wherein the cutting apparatus includes at least one knife with at least one tooth, the at least one tooth including a single leading surface at least a portion of which is formed in a sideward plow angle shape;
- and
- cutting a plurality of rows of projecting members on the contact surface of the backing plate, wherein each projecting member extends outwardly from the plate in a shaped configuration resulting from the sideward plow angle shape of the tooth.
