Abstract

The disclosure relates to a brake caliper for a disk brake, comprising a support structure having a bridge and at least one bridge finger. The at least one bridge finger has a brake lining side, an outer side, and a bore introduced into the outer side. The bore has a bore wall, a bore groove let into the bore wall. A cover having a pin projects into the bore and a pin groove extending into the pin circumferential surface, A sleeve is arranged between the bore wall and the pin circumferential surface and has a sleeve body
The sleeve has a spring arm which is bent outward in the radial direction away from the sleeve body and/or a spring arm which is bent inward in the radial direction away from the sleeve body. The outwardly bent spring arm engages into the bore groove and/or the inwardly bent spring arm engages into the pin groove.

First claim

The invention claimed is:

1 . A brake caliper for a disk brake, comprising:
a support structure having a bridge and at least one bridge finger which has a brake lining side, an outer side, and a bore introduced into the outer side and having a bore wall, a bore groove extending into the bore wall, a cover having a pin which projects into the bore and a pin groove extending into the pin circumferential surface, and a sleeve arranged between the bore wall and the pin circumferential surface and having a sleeve body, an outwardly bent spring arm, and an inwardly bent spring arm,
wherein the outwardly bent spring arm engages the bore groove and the inwardly bent spring arm engages the pin groove to secure the cover to the support structure; and
wherein the bore groove comprises a groove base that is inclined relative to the bore wall and two side walls that are not oriented at a right angle to the bore wall, such that a width of the bore groove increases from the groove base toward the bore wall.

2 . The brake caliper as claimed in claim 1 , wherein the pin groove comprises a groove base that is inclined relative to the pin circumferential surface such that a radial distance between the pin circumferential surface and the groove base decreases in a direction toward an end face of the pin.

3 . The brake caliper as claimed in claim 1 , wherein the sleeve has a sleeve longitudinal axis and wherein, in an unloaded state, a bending angle of the outwardly bent spring arm and the inwardly bent spring arm relative to the sleeve longitudinal axis is less than 90°.

4 . The brake caliper as claimed in claim claim 1 , wherein the sleeve comprises a lip directed inward in a radial direction on which an end face of the pin rests, and wherein the lip is formed by a plurality of folded-over portions separated by incisions.
