Abstract
The clutch disc for a motor vehicle friction disc clutch comprises a hub part and a disc part mounted rotatably on the hub part. The disc part carries clutch friction linings and is supported through springs with a multi-stage rotational elasticity characteristic on the hub part. Between a side disc of the disc part and a hub disc, an axially resilient control disc is braced. The control disc is supported through a first friction face pair radially within the space defined by the springs on the hub part and through a second friction face pair radially outside this region on the side disc of the disc part. A tab of the control disc couples the control disc with limited rotational play with the hub part. The friction face pairs determine friction torques of different magnitudes and are effective in alternation.
