  • Patent number: 5526714
    Abstract: A torsional vibration damper for the drive line of a motor vehicle includes an input damper part rotatable about an axis of rotation, an output damper part rotatable about the axis of rotation relative to the input damper part over a limited relative angle of rotation, a spring system coupling the two damper parts together in a rotationally elastic manner, and a friction ring axially clamped between friction surfaces of the damper parts by an axial spring force. The friction ring has a carrier of substantially annular disk-shaped form and consisting substantially of fibrous-material-reinforced synthetic plastic material and friction linings affixed to the carrier. The friction linings are composed of a synthetic plastic material substantially devoid of reinforcing materials and projecting beyond the carrier on both axial sides by a distance corresponding to a predetermined abrasion volume. The carrier of the friction ring is coupled to one of the damper parts.
