Automatic slack adjuster for vehicle, braking system and wheelset having an automatic slack adjuster

An automatic slack adjuster (1) for braking systems (100) of automotive vehicles, in particular for drum brakes of commercial vehicles, the slack adjuster (1) comprising:

• a lever (3) configured to be operatively coupled to a push rod (103) of a brake actuator (101), and further configured to pivot about a rotational axis (R) when actuated by the push rod (103), the rotational axis (R) having a predetermined fixed location relative to the vehicle,
• a stroke indicator label (7) arranged on the lever and configured to designate, for the automatic slack adjuster (1), a predetermined zero stroke position, a working stroke range, and an overstroke range, and
• a stroke indicator element (9) that is configured to visually indicate the current stroke level of the automatic slack adjuster (1) between the predetermined zero stroke position (7a), the working stroke range (7b), and the overstroke range (7c) on the indicator label (7) via relative movement between the stroke indicator element (9) and the stroke indicator label (7),
• wherein the stroke indicator element (9) is positioned on the automatic slack adjuster (1) such that the lever (3) pivots relative to the stroke indicator element (9) about the rotational axis (R), and
• wherein the stroke indicator element (9) includes a mounting interface (18) configured to attach the stroke indicator element (9) to a fixed location relative to the vehicle.
