Piston for a hydraulic brake and method for production thereof

Piston for a hydraulic brake and method for production thereof

A piston for a hydraulic brake configured as a bowl, open on one side, with a longitudinal axis, a wall and a bottom, and is delimited on an open end face by a rim with an axial abutment surface which is movable into abutment on a brake pad. The bottom has an essentially plane outside surface, a wal...

description A piston for a hydraulic brake configured as a bowl, open on one side, with a longitudinal axis, a wall and a bottom, and is delimited on an open end face by a rim with an axial abutment surface which is movable into abutment on a brake pad. The bottom has an essentially plane outside surface, a wall thickness of the bottom is thicker than a minimum wall thickness of the wall, and at a transition area between bottom and wall, a wall thickness of the wall is continuously increasing towards the bottom, thus, the wall passing over into the bottom in a slope. Furthermore, a method including forming a disc-shaped round blank into a bowl-type hollow cylinder, and upsetting the hollow cylinder in its longitudinal axis so that the bottom material is thickened due to the upsetting operation.
