FIELD: machine building.
SUBSTANCE: piston is made by means of pressure shaping of a flat sheet and is formed as a one side open cup with a longitudinal axis, a wall and a base. Thickness of walls of the base is greater than the minimum wall thickness. It is limited on the open end side by an edge with the axial surface flanking the friction pad of a brake lining. This flanking surface is greater than the cross sectional area at the wall its thinnest point. In the transition area between the base and the wall thickness continuously increases to the base, so the wall becomes a sloped base. According to the method of the piston manufacturing a disc-shaped work piece is pressure shaped to produce a hollow cylinder-type cup with a longitudinal axis and then the hollow cylinder is compressed along its longitudinal axis, resulting in increased base wall thickness as compared to the original material.
EFFECT: manufacture of a piston with a design optimised for a structural stress.
