Abstract:
A clutch disk for a friction clutch in a motor vehicle, comprising:a flywheel having a friction surface;a contact pressure plate having a friction surface arranged opposite the flywheel friction surface;a hub with an internal toothing fittable to a transmission shaft so as to be rotatably fixed relative to the transmission shaft, the transmission shaft having a longitudinal axis;at least one facing carrier connected with the hub so as to be fixed with respect to rotation relative thereto; andat least one friction facing ring arranged perpendicular to the longitudinal axis so as to be axially tensionable between the friction surface of the flywheel and the contact pressure plate for a transmission of torque, the friction surface of the contact pressure plate being configured to be conical in a thermally unloaded state such that a radial outer region of the radial outer region of friction surface of the contact pressure plate is at a smaller distance from the friction surface of the flywheel than a radial inner region of the pressure plate friction surface so that the the contact pressure plate is first contactable with a radial outer region of the friction facing ring and under thermal loading the contact pressure plate completely contacts the friction facing, the friction facing ring having a friction coefficient that is smaller in the radial outer region than in a radial inner region.
