Abstract
A clutch disk for a friction clutch, especially for internal combustion engines, with a hub, two friction disks which are arranged concentric to the hub and are connected thereto. A plurality of facing spring elements are connected with the friction disks so as to be rotationally fixed relative thereto, and are provided between the friction disks in the circumferential direction. The facing spring elements are curved in a wavy manner and nested against one another in pairs such that they exert a force on the friction disks in the axial direction. The facing spring elements which are nested against one another are designed so that their ends which are directed in the circumferential direction are located at a distance from one another in the no-load state of the clutch.
