Estimating the term…
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, rationalised 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.
A double cup-shaped piston, a disk brake comprising an electromechanical parking brake apparatus, and a method for chipless production of a piston the disk brake, there being a piston wall which is provided to be seated with a free edge firstly on a rear plate of a friction lining, and the piston secondly having an integral dome starting from a piston crown, which dome forms an open receptacle for an actuating apparatus of the electromechanical parking brake apparatus diametrically with respect to the edge of the piston.
