Abstract
A pressure plate assembly comprises a housing and a pressure plate that is axially movably arranged therein. A diaphragm spring is positioned between the housing and the pressure plate and rests on the pressure plate via a wear compensation device. A clearance indicator with a wear detection section is inserted through an opening in the pressure plate. The clearance indicator also includes an activating lever section 30 that interacts with the wear compensation device to compensate for wear that has occurred on friction linings during operation. The clearance indicator is biased by a spring part in a friction clamp seat in the opening or a clamping seat section. The spring part produces a force substantially orthogonal relative to a rotational axis A in a radially outward direction.
