摘要： A brake disc (1) including at least one friction ring (2) and a brake hub (3) connected to the friction ring (2) for conjoint rotation. A side wall section (17) of the brake hub (3) has a plurality of radially oriented deformations (5). A contact surface (7) extending in the radial direction is formed by these deformations (5), and a rotationally fixed connection (8) is established by the contact surface (7) between the friction ring (2) and the brake hub (3). A ratio Da/Di formed from the outer diameter Da of a side wall section (17) of the brake hub (3) and an inner diameter Di of the friction ring (2) is at most 1.01.

摘要： A thin-walled piston having a multi-part construction for a brake caliper, the piston having a one-piece design with the form of a pot, which is open on one side, a longitudinal axis, a wall and a piston floor, and which can be applied in the region of the piston floor with an axial contact surface to a brake lining, wherein a tubular insert with a cone is fixed in the interior of the piston, the insert forming a bearing for a bushing.

摘要： A pot-shaped, cold-formed steel brake piston as a pot which is open on one side includes a base and a wall including inner and outer walls, a radially inwardly configured groove is open in a radially outward direction and forms, radially at the inside, a groove bead projection. The open side of the pot ends as a bearing for a friction pad backplate. Interfaces integrated at the inside on the end side serve a) for the fixing between friction pad and steel brake piston and b) as support bearing for spring mounting the friction pad. An aspect is a further improved steel brake piston of the new generation. The minimum inner diameter dimin is axially set back in the direction of the base by a multiple of the length of a wall thickness s, and the minimum piston inner diameter dimin is formed by the groove bead projection.

摘要： The invention relates to a brake piston 1 for a brake caliper 9 of a disk brake, which is produced using working processes from a metallic material, in particular from a flat metal sheet, and is formed in one piece as a unilaterally open pot with a piston longitudinal axis A, with a piston wall 2 and with a piston head 3. There is a need for robust and light as well as alternatively constructed, efficiently producible and well guided brake pistons. The object is achieved firstly in principle on the basis of a cup-shapedly worked brake piston blank 19, in that at least one locally defined, i.e. partially cold-upset or partially ironed, cylindrical piston wall portion is present with a partially deformed piston wall 2 which is configured in adaptively modified manner by plastic material deformation by means of material redistribution (flow) including strain-hardening of its piston wall thickness of sl−x.

摘要： The invention relates to a cold-formed steel brake piston 1 for a motor vehicle partial-pad disc brake brake pad with a thin-walled structure as a cup open at one end and comprising a base 2 and a wall 3 with a radially outwardly impressed groove 6 in the wall 3 and with a radially inwardly impressed wall projection 7. The invention has the object of providing a further improved stable steel brake piston construction with an improved interface which can be used flexibly and cost-effectively for both large-bore and small-bore steel brake pistons 1. This object is accomplished by making the wall 3 with at least one groove 14 and at least one land 15 at a distance from wall projection 7 profiled in such a way that wall 3 has wall surface areas of varying thickness which are spaced apart from each other in the circumferential direction with a spacing V.
