Estimating the term…
Disk brake including a brake caliper and an application device arranged therein for applying force to the brake pads of the disk brake, wherein a component of the application device is a brake lever which can be actuated by a force element and preferably by a pressure cylinder and is composed of a lever arm against which the force element is supported and an application shaft. The application shaft is supported, on one side, against a pressure piece operating in the direction of the brake pads and, on the other side, with the interposition of a shell, against a channel arranged on the inside of the brake caliper, wherein the curvature of the shell is complementary to the curvature of the channel. In order to develop the disk brake and the shell assembly by constructive measures so as to prevent the shell assembly from moving out of the original position even in the case of long-term use and under frequent load caused by braking, an opening of a bore is located in the channel.
A disk brake comprising a brake caliper and an application device arranged therein for applying force to the brake pads of the disk brake, wherein a component of the application device is a brake lever which can be actuated by a force element, which brake lever is composed of a lever arm against which the force element is supported and an application shaft which is supported, on one side, against a pressure piece operating in the direction of the brake pads, and, on the other side, with the interposition of a shell, against a channel arranged on the inside of the brake caliper, wherein the curvature of the shell is complementary to the curvature of the channel, characterized in that an opening of a bore is located in the channel, in that a passage produced by deformation of the shell material is formed on the shell, facing the channel, which passage extends into the bore in the form of a collar to produce a positive fit between the shell and the channel, and in that a shaped element is arranged in the passage, the outer diameter of which shaped element is equal or nearly equal to the inner diameter of the passage.
A shell assembly for pressure transmission in an application device of a disk brake, comprising a shell on which, on one side, a concave pressure transmission surface for supporting a brake lever of the application device and, on the other side, a convex pressure transmission surface for support against an abutment designed as a channel is formed, characterized in that a passage in the form of a collar produced by deformation of the shell material is formed on the shell on the side of the convex pressure transmission surface, and in that a shaped element, the outer diameter of which is equal to the inner diameter of the passage, is arranged in the passage.
