A clutch disk includes a hub area and a plurality of friction lining elements, which are supported on the hub area and arranged in sequence in the circumferential direction relative to a clutch disk rotational axis (A). These elements provide at least part of an associated friction surface area, where the friction lining elements are intended to make frictional contact with an associated opposing friction surface of a flywheel, a pressure plate, or the like. At least one friction lining element is supported so that the pressure exerted by its friction surface area against an opposing friction surface can change in response to a change in the sliding frictional interaction between its friction surface area and an opposing friction surface area which is or can be associated with it.

Clutch disk

A multiple plate friction clutch with a hub which has external gearing and a peripheral groove. A ring or a ring segment is placed in this groove and is used to fix the hub in place axially with respect to the clutch plates, which are non-rotationally engaged by means of internal gearing with the external gearing of the hub.

Multiple plate friction clutch with axial stop

The invention relates to the production of a multi-part hub part for a clutch disc, wherein all parts are joined together by a weld. Different designs are possible, depending on the various welding processes. The apertures for damper springs can be produced very exactly in the hub disc owing to the production in individual parts. It is also possible to arrange lubricant reservoirs in a simple manner in the region of the points of separation of the individual components.

Hub part for a clutch disc

A cluch disc of a motor vehicle clutch comprises a clutch disc hub and a hub flange integral therewith. The hub flange is provided with a plurality of coherent windows each of which receives both a helical compression spring and an interconnection bolt interconnecting the cover plates of the clutch disc which are angularly movably mounted on the clutch disc hub. The window is closed at its radially outer side by an uninterrupted web.

Clutch disc arrangement

The clutch disc for a motor vehicle friction clutch comprises a hub (1) and a friction lining carrier mounted rotatably through a limited angle of rotation on the hub (1), with side discs (9, 11) firmly connected into one unit and arranged axially on both sides of a hub flange (7). The friction lining carrier is mounted through a guide ring (15) on the hub (1). The guide ring (15) comprises a ring part (41), which can be a component of a friction damper (29), and a ring extension piece (53) guiding the friction lining carrier radially on the hub (1). The ring extension piece (53) is made radially resilient and centers the friction lining carrier radially without play on the hub (1). The guide ring (15) can comprise axial tongues or a coating of elastic material for the generation of initial radial stress forces.
