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: 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 friction lining holding spring and the equipped component/assembly, specifically a motor vehicle disc brake lining, including the friction lining holding spring. The friction lining holding spring includes an offset knee piece of a U-spring leg, which branches off at an angle from a largely flat U base section, and wherein the largely flat base section has a fastening tab with a cup-shaped rim hole including a through-opening for the purpose of fixing on a backplate of the friction lining, wherein each knee piece has integrated gearing, which is in particular designed as an uneven brake piston insertion trajectory such that, when a brake piston is inserted, there is a predefined gearing reduction effect for the purpose of automatically influencing or modelling the necessary force requirement.

摘要: A double cup-shaped piston for a disc brake including an electromechanical parking brake device. An aspect of the invention permits an improved compromise between easier operability, rationalized component logistics in piston production, reduced hydraulic volume uptake in cooperation with the wheel brake periphery, and enhanced fatigue strength under maximum collective stress, in particular for heavy-duty applications of a disc brake with an electromechanical parking brake device. The problem is solved by the presence of a piston wall, which is provided, on the one hand, to sit with a free edge on a rear plate of a friction lining, and wherein the piston, on the other hand, includes an integral dome which forms an open receptacle for an actuator arranged diametrically to the edge of the piston.
