Abstract
The invention relates to a torsional damper () in a clutch disc arrangement () arranged to indicate damping performance of the torsional damper (). The torsional damper () comprises a driven plate (), an output hub (), intermediate friction plates () arranged on either side of the driven plate () and a resilient member () arranged to press the intermediate friction plates () against the driven plate () or against the output hub () with a pressure force. The intermediate friction plates () and the resilient member () are rotationally fixed to the output hub () or the driven plate () forming a rotationally fixed stack (). The rotationally fixed stack () comprises a detection friction plate () rotatably decoupled from the rotationally fixed stack () and arranged in the rotationally fixed stack ().
