Patent ID: 8439170

Claim:
A self-amplifying electromechanical disc brake, having a brake caliper and a housing in which electromechanical parts of the disc brake are accommodated, wherein the brake caliper comprises two generally parallel first and second caliper plates connected together by cross pieces, each caliper plate having an inner surface facing toward the other caliper plate and an outer surface facing away from the other caliper plate, said first caliper plate having a self-amplifying device attached to its inner surface, said self-amplifying device being equipped with a ramp mechanism, wherein the housing is part of the brake caliper and comprises a dimensionally stable, hollow body that reinforces the brake caliper against bending and/or torsion, said housing being integrally joined to the outer surface of the first caliper plate, wherein the brake caliper further comprises a pad support plate positioned between said caliper plates, said pad support plate having a friction pad attached thereto, wherein said pad support plate is attached to said first caliper plate by a tubular bellows located between said pad support plate and said first caliper plate, and said tubular bellows surrounds said self-amplifying device, wherein a reinforcing rib for reinforcing the brake caliper is integrally joined to and projects toward said pad support plate from the inner surface of the first caliper plate, and wherein the first caliper plate, the housing and the reinforcing rib are embodied as a single piece.
