Abstract
A torque transmitting and torsion damping apparatus includes a torsion damper and a friction clutch between a first inertia body and a second inertia body that is supported by said first inertia body for relative rotation. The friction clutch includes a friction plate and a pressure plate that is pressed against the friction disc due to the action of a Belleville spring. The pressure plate has bent-free (straight) projections radially outwardly extending into cutout grooves of the first inertia body. This arrangement allows relative axial movement of the pressure plate to the first inertia body.
