A multi-part piston for a brake saddle of a hydraulically and/or mechanically and/or electromechanically actuated disk brake is described herein. The piston is a pot open on one side and including a base and a wall attached thereto in one piece. The base can be impinged by brake pressure coming from the inside of the pot so that an outward-facing abutting surface of the base can be pressed against a brake lining. The inside of the pot receives at least one pressure piece associated with a parking brake mechanism. For simplified manufacture in the form of a modular piston system for use in various applications, it is proposed that the pressure piece and the base comprise conical surfaces facing one another for transferring braking pressure.

Multi-part piston construction for a brake caliper of a disk brake

A piston for a brake caliper of a disc brake constructed as a pot which is open at one end, having a longitudinal axis, a wall, and a piston head. The piston is supported in a cylinder of the brake caliper such that it can be moved along the longitudinal direction, and it can be placed against a brake pad in the region of the piston head by an axial contact surface. When the piston is subjected to pressure by a hydraulic fluid, the piston moves in the cylinder and presses the brake pad against a brake disc. A projection having a conical surface is provided on an inner surface of the piston head. A recess is provided, which is substantially at the same distance from the longitudinal axis as the projection on the inner surface of the piston head, on an outer surface of the piston head.

Piston for a brake caliper of a disc brake

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.
