  • Vibration damper
    Patent number: 5415062
    Abstract: A vibration damper assembly comprises a torsional vibration damper with torsional springs, a mass body, and a resilient drive plate which serves as a bending stress damper. With a bearing on a reinforcement block connected to the crankshaft, the torsional vibration damper has an output member rotatably supported by the crankshaft. The resilient driver plate is operatively disposed in torque transmission relationship between the crankshaft and the mass body in such a manner as to coextend radially outwardly from the crankshaft with the torsional vibration damper.
