Disk brake and drive element of an adjusting device of a disk brake

The invention relates to a disk brake for a vehicle, preferably a utility vehicle, comprising a brake caliper, which reaches around a brake disk and brake pads on both sides of the brake disk, a brake application device (5), which can be actuated by means of a force element, preferably a pneumatic force element, an adjusting device (20) for compensating the brake-pad wear and the brake-disk wear, which is arranged on an adjustment axis (L) extending in the brake application direction and is provided with a drive element (27) that can be rotated about the adjustment axis (L), a brake lever, which is part of the brake application device (5) and which is composed of a brake application shaft (11), which is supported with respect to the brake caliper and with respect to a pressure piece (8) working against one of the brake pads, and of a lever arm (12), which can be pivoted with the brake application shaft (11) and the pivoting center line of which extends at a right angle to the brake application shaft (11) and which is provided with a support (16) for the force element in the region of the outer end (12A) of the lever arm, wherein the brake lever (10) has, in extension of the lever arm (12) in the inward direction, a clearance (40), through which the adjustment axis (L) extends, and a transmission, which couples the brake lever (10) to the drive element (27) and is composed of a first transmission element (31) on the brake lever (10) and a second transmission element (32) on the drive element (27), which second transmission element interacts with the first transmission element. In order to provide installation space for the brake application shaft, the first transmission element (31) is arranged at the inner end (12B) of the lever arm (12) in the plane (E) defined by the pivoting motion (S) of the lever arm (12).
