Abstract: Each clutch disk has a hub area designed to be connected nonrotatably to a power takeoff element and a friction surface area designed to be clamped between opposing friction surfaces. Each clutch disk has a torsional vibration damper arrangement including two cover disk elements connected to the hub area for rotation in common, and a central disk element connected to the friction surface area for rotation in common. The central disk element is or can be brought into torque-transmitting connection with the cover disk elements via a damper element arrangement. The central disk element has a damper element interaction area and, radially outside the damper element interaction area, a friction surface carrier area, which is offset with respect to the damper element interaction area in the direction of an axis of rotation.

Abstract: A pressure plate assembly for a friction clutch, which assembly includes a housing; a pressure plate connected to the housing for rotation in common around an axis of rotation and which is free to move axially with respect to the housing; a stored-energy device, which pretensions the pressure plate in the axial direction with respect to the housing; a wear-compensating device which acts in the path of support between the stored-energy device and at least one of the housing and the pressure plate and comprises at least one wear-compensating element which is free to move when wear occurs and/or when wear is compensated; an indicator arrangement, comprising at least one indicator opening in the housing and at least one indicator element on a wear-compensating element.

Abstract: A housing arrangement for a friction clutch, especially for a multi-disk clutch, where the housing arrangement is designed approximately in the shape of a cup and is provided with a bottom area and an edge area for connection to a flywheel. At least one air through-opening is provided in the bottom area, each opening being bounded by a front edge and a rear edge with respect to the direction of rotation, the front edge being axially offset toward the interior of the housing with respect to said rear edge.

Abstract: A transport-securing arrangement for a pressure plate assembly of a multi-disk clutch including a housing arrangement connectable to a flywheel, a pressure plate coupled to the housing arrangement for common rotation therewith, a stored-energy device having one side supported on the housing arrangement and another side supported on the pressure plate arrangement. The pressure plate assembly also includes an intermediate plate connected to the housing arrangement for common rotation therewith and a first clutch disk with a friction surface area positioned between the pressure plate and the intermediate plate. The transport-securing arrangement comprises a plurality of connecting elements, preferably bolt elements, for tightly connecting the intermediate plate to the housing arrangement.

Abstract: A process for adjusting a friction clutch system of the type including a housing arrangement; a pressure plate; a stored-energy device supported against the housing and the pressure plate; a wear-compensating device installed in the path of support between the stored-energy device and one of the housing arrangement and the pressure plate, this device having a detection element on the pressure plate, which in association with a stop element fixed with respect to the housing arrangement, detects the amount of wear which has occurred in the friction clutch; a clutch-release mechanism for exerting force on the stored-energy device in the direction opposite its relaxation direction in order to carry out release operations; and a transmission shaft braking arrangement which is activated when a brake-release position is reached during a clutch-release operation.

Abstract: A pressure plate assembly for a multi-disk clutch includes a housing arrangement, a pressure plate mounted in the housing arrangement with freedom to move in the same direction as an axis of rotation but connected to the housing with essentially no freedom of rotation and an intermediate plate mounted in the housing arrangement with freedom to move in the same direction as the axis of rotation but connected to the housing with essentially no freedom of rotation. A release distance preset arrangement for the intermediate plate includes at least one sensing element on the intermediate plate which rests on an assembly which shifts position during the performance of a releasing movement of the pressure plate. The at least one sensing element allows the intermediate plate to execute a releasing movement corresponding to the shift of this assembly. The at least one sensing element contacting the assembly is pretensioned by an intermediate plate release force-generating arrangement acting on the intermediate plate.
