A wear adjustor adjusts the wear of brake pads and a brake disc of a pneumatic disc brake having a rotary-lever-actuated brake application device. The adjustor is insertable into an adjusting spindle and attached to a caliper of the disc brake by way of a mounting disc. An axial bearing is formed axially on one side of a drive ring and a ball ramp coupling with a freewheel function is formed axially on the opposite side of the drive ring. The ball ramp coupling has balls, has the drive ring arranged at the drive-input side axially between the axial bearing and the balls thereof, and has a drive-output-side clutch ring. A cone clutch is arranged between the drive-output-side clutch ring and a spring sleeve for a cylindrical spring. A torque-dependent coupling with positive restraint is arranged axially between the cone clutch and the spring sleeve. |
