Abstract

A wear adjustor adjusts the wear of brake pads and a brake disc of a pneumatic disc brake having a rotary lever brake application device. The wear adjustor is insertable into an adjusting spindle and attached to a caliper of the disc brake by a bearing disc. An axial bearing is formed axially on a 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 includes balls and a drive socket which is arranged axially, on the drive side, between the axial bearing and the balls thereof, a cone coupling being arranged between the coupling ring on the output side and an elastic sleeve for a cylinder spring. The output-side coupling ring is designed for a working rotational angle defined by at least one fixed abutment.
