Torsional vibration damper arrangement for use at crank shaft of motor vehicle, has elastomer body arranged between primary mass and secondary mass that includes two mass parts rotatably formed around rotational axis relative to each other

摘要

The arrangement (10) has a primary mass (20) rotatable around a rotational axis, and a secondary mass (30) rotatable relative to the primary mass around the rotational axis. An elastomer body is arranged between the primary mass and the secondary mass. The secondary mass includes two L-shaped mass parts having different masses, which are rotatably formed around the rotational axis relative to each other. Measuring rods are arranged between the mass parts, and are supported as sliding-movable in distance to each other.
