초록 ▼

Cushions for disc brake pads are disposed between the brake pads and their caliper pistons or caliper fingers. The cushions possess such characteristics of resilience that, during braking action, brake pads follow irregularities and ride over high spots on rotor faces. This action significantly reduces uneven frictional drag, which lowers braking temperature increasing braking efficiency and brake system longevity. Each cushion comprises a resilient body which is further comprised of either a material, such as an elastomeric pad, or a structure such as a compressible spring or other apparatus.

대표청구항 ▼

1. A cushion for reducing uneven frictional drag between a disc brake pad and a disc brake rotor caused by irregularities on a friction face of the disc brake rotor, the cushion comprising: a cushion shape, the cushion shape allowing the cushion to fit between a force producing element of the disc brake assembly and a brake pad backing plate;the cushion placed between the force producing element and the brake pad backing plate, the cushion positioned to prevent the force producing element from directly contacting the brake pad backing plate;the cushion having a thickness to accommodate lateral movement of the brake pad as the pad passes the irregularities of the friction face;the cushion comprising resilient elastomeric material with Compression Set of less than about 30% when tested at about 200 C for about 70 hours, resilient response at frequencies from about 1 Hz. to about 500 Hz to accommodate lateral movement as the disc brake pad passes the irregularities of the friction face, and Tan Delta of from about 0.01 to about 0.4 at frequencies from about 10 Hz. to about 30 Hz. and temperatures from about ambient temperature to about 204 C; andthe cushion preventing generation of excessive heat caused by the uneven frictional drag arising from interaction between the irregularities and the brake pad. 2. The cushion of claim 1 where the cushion is positioned between the force producing element of a brake assembly and the brake pad backing plate such that the cushion distributes force uniformly over the friction face of the disk brake rotor, the cushion reducing uneven heating of the brake rotor. 3. The cushion of claim 1 where the cushion is placed adjacent the backing plate of the disc brake pad in resilient elastomeric communication with the force producing element of the brake system to absorb lateral movement of the disc brake pad as the disc brake pad passes over irregularities in the friction face of the brake rotor, the cushion reducing excessive heating of the brake rotor. 4. The cushion of claim 1 where the resilient material comprises an elastomeric material having a Compression Set of less than about 15% when tested at about 200 C for about 70 hours. 5. The cushion of claim 1 where the resilient material comprises an elastomeric material having a Tan Delta from about 0.02 to about 0.05 at frequencies from about 6 Hz to about 20 Hz in the temperature range from about 93 C to about 260 C. 6. The cushion of claim 1 where the resilient material comprising the brake pad cushion is shaped to match the shape of a brake piston end. 7. The cushion of claim 1 in which the resilient material is a material having a synchronous response that can follow the brake rotor irregularities as they pass by the brake pad at frequencies from about 1 Hz to about 500 Hz. 8. An apparatus for reducing uneven frictional drag between a disc brake pad and a brake rotor friction face of a brake assembly due to irregularities on the brake rotor friction face comprising: a brake caliper;a brake rotor having the brake rotor friction face;a brake piston for exerting force to press against the brake rotor friction face;a brake pad comprising a backing plate and a friction pad for receiving force from a force producing element of the brake assembly to press against the brake rotor friction face; anda cushion disposed adjacent the brake pad backing plate in resilient communication with the force producing element of the brake assembly, the cushion comprising: a cushion shape, the cushion shape allowing the cushion to fit between the force producing element of the disc brake assembly and the brake pad backing plate;the cushion placed between the force producing element and the brake pad backing plate, the cushion positioned to prevent the force producing element from directly contacting the brake pad backing plate;the cushion having a thickness to accommodate lateral movement of the brake pad as the pad passes the irregularities of the friction face;the cushion comprising a resilient elastomeric material with Compression Set of less than about 30% when tested at about 200 C for about 70 hours, resilient response at frequencies from about 1 Hz. to about 500 Hz to accommodate lateral movement as the disc brake pad passes the irregularities of the friction face, and Tan Delta of from about 0.01 to about 0.4 at frequencies from about 10 Hz. to about 30 Hz. and temperatures from about ambient temperature to about 204 C; andthe cushion evening the distribution of force exerted by the brake pad against the brake rotor friction face to reduce excessive brake heating. 9. The apparatus of claim 8 wherein the force producing element of the brake assembly is the brake piston. 10. The apparatus of claim 8 wherein the force producing element of the brake is the brake caliper. 11. The apparatus of claim 8 wherein the resilient material comprising the cushion is a resilient material having Tan Delta from about 0.01 to about 0.04 at frequencies from about 10 Hz to about 30 Hz in the temperature range from about 93 C to about 204 C. 12. The apparatus of claim 8 where the resilient material comprising the cushion is a resilient material having a Tan Delta, determined from dynamic mechanical analysis, from about 0.02 to about 0.05 at frequencies from about 6 Hz. to about 20 Hz. in the temperature range from about 93 C to about 260 C. 13. The apparatus of claim 8 having the resilient material comprising the cushion shaped to match the shape of the brake piston resting on the brake pad. 14. The apparatus of claim 8 comprising the cushion disposed on the backing plate of the brake pad to provide cushioning between the brake pad and the force element providing pressure on the brake pad to cause the brake pad to press on the brake rotor friction face.
