Abstract
A wear adjustor is provided for adjusting the wear of brake pads and a brake disc of a pneumatic disc brake having a brake application device actuated by a rotary lever. The wear adjustor is preferably inserted into an adjusting spindle of the brake application device. 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 has balls and a drive socket which is arranged axially, on the drive side, between the axial bearing and the balls thereof, a cone clutch being arranged between the clutch ring on the output side and an elastic sleeve for a cylinder spring. The cone clutch has the output-side clutch ring and a cone socket connected to the elastic sleeve, and clamping balls are arranged between the output-side clutch ring and the cone socket.
