VEHICLE BRAKE DRUMS HAVING BRAKING WALLS ENHANCED WITH COMPRESSIVE STRESSES

摘要

A brake drum for a vehicle braking system includes a closed end, an open end opposite the closed end, a braking wall axially extending between the open end and the closed end, and a compression device that applies a radial compressive force to the braking wall thereby increasing the thermo-mechanical fatigue resistance of the braking wall. A first restraining tab on the braking wall to axially restrain the compression device on the braking wall.
