Torsional vibration damper with wound wire springs in a driving sheave

摘要

The torsion oscillation damper, or decoupler, has a drive disk (11) with a hub (12) and a disk rim (14) rotating within each other, e.g. for a crankshaft or camshaft at an internal combustion motor. At least two coiled wire springs (15,16) are coaxial to the hub, with one end (18) at the hub and the other end (17) against the disk rim in the direction of rotation. The wire springs are wound in opposite directions, tensed against each other.
