Abstract: The present invention concerns a method for manufacturing a part consisting at least partially of a metal alloy. The method includes a metallurgical manufacturing step a1) consisting of manufacturing the body of the part. The method subsequently includes a reinforcing step a2) consisting of forming a local reinforcement directly on the body, in an area of the part that is under stress. The invention also concerns a method for optimising a part.

Abstract: Disc brake incorporating an assembly of a crown (11) and a brake bowl (12), with the brake bowl (12) incorporating a circular base (12a), extended radially and externally by lugs (12b), with the crown accommodating a number of fingers (13) protruding externally into the interior volume of the crown (11). The lugs (12b) have a staged configuration with, at the end, a hood form (12d) internally establishing a housing for each of the fingers (13); the lugs have an access opening in unclosed ‘U’ form; the lugs (12b) are oriented in the same direction, with their opening part on the same side. After assembly of the brake bowl and the crown, the lugs are closed around the fingers, by distortion and flowage of the material around the finger, leaving them a capability for axial movement.

Abstract: The process includes: definition of the final hollow part in its internal portion after forging with deformation of solid or thinned-down sections; modelling of the solid or thinned-down sections; formation of the thinned-down sections by recyclable single-material cores positioned at places requiring zones with a thinned-down section, and modelling of the cores; after modelling, definition of the semi-finished product and of the cores in their initial forms having a different configuration from the forged cores; after casting of metal around the cores, in the prior initial form, striking of the semi-finished product with its cores resulting in the part and its cores being deformed from their initial shapes to their final shapes; fettling of the burrs; and removal of the cores.
