The invention relates to a disk brake, in particular for utility vehicles, comprising a brake disk, a brake caliper, at least one actuation device lying within the brake caliper on a side of the brake disk, an axially movable device, which moves a brake pad axially toward the brake disk by means of at least one actuating spindle (7) when the brake is actuated, wherein the actuating spindle (7) can be rotated, has an external thread (7a), and is screwed into a threaded bore in the movable device, and an adjusting transmission (11), which can be rotated about an axis (A-B) lying parallel to the axis of rotation of the brake disk and which, in the event of rotation in a first direction of rotation causing adjustment, rotates the actuating spindle because of a rotational coupling acting in said direction of rotation, wherein the adjusting transmission (11) has a thread device (14), which, at least in the event of rotation in a second direction of rotation opposite the first direction of rotation, engages with the external thread (7a) of the actuating spindle (7) and screws the adjusting transmission (11) in relation to the actuating spindle. |
