Abstract

The invention relates to an adjustment mechanism for a vehicle disk brake, which is provided with an adjustment device for compensating the operation-induced wear on the brake linings and the brake disk, wherein the adjustment device has the following components: —a drive element (25) which is rotatably arranged within the housing of the disk brake on an axis (A) parallel to the axis of rotation of the brake disk and which can be set in rotation by a brake application device; —a shaft (40) which is arranged centrally on the axis (A), on which the drive element (25) is rotatably mounted; —a cardanic rotary bearing (45) which supports the shaft (40) in an opening (1A) of the housing in a pendulum-like manner and which is made at least partially of a deformable rubber or elastomer ring (46) and a steel ring (47) which is attached therein. In order to further develop the mentioned adjustment mechanism so that it can be produced more economically and requires only a small number of components, the steel ring (47) is supported in a sliding manner against a cylindrical bearing section (50) of the shaft (40), and a coupling consisting of a first coupling part (51), which is rotationally fi…
