PISTON FOR A BRAKE CALIPER OF A DISK BRAKE

摘要

The invention relates to a piston for a brake caliper, which can be actuated in combined fashion, of a disk brake, which piston 1 is produced by shaping processes from a metallic material, in particular from a planar metal sheet, and which piston 1 is formed as a pot which is open on one side and which has a longitudinal axis, a wall and a piston crown, and which piston has a twist prevention facility for a drive nut. The invention is based on the problem of providing a robust piston construction which is better capable of tolerating erroneous repair work. To solve the problem, it is proposed that the twist prevention facility has, between the piston and drive nut, at least one reinforcement for protecting against plastic deformation of at least one driver.

主权项

1. A piston (1) for a brake caliper of a disk brake, which piston (1) is produced by forming processes from a metallic material, in particular from a flat metal sheet, and which piston (1) is designed as a pot which is open on one side and which has a longitudinal axis, a wall and a piston head (11), and can be placed against a brake pad by means of an axial contact surface (12), and which piston (1) has at least one twist prevention means between the piston (1) and a drive nut (13), characterized in that the twist prevention means has at least one integrated reinforcement, which serves to protect the piston (1) against plastic deformation by the drive nut (13).
