DEVICE FOR ABSORBING OSCILLATIONS, ESPECIALLY AN OSCILLATION DAMPER

摘要

The invention relates to a device for oscillation damping in rotating constructional elements, comprising two oscillating masses, a primary and a secondary mass, that can be rotated in a limited manner in relation to each other in the peripheral direction. The primary and the secondary masses can be coupled to each other by means of a damping and spring coupling. The device comprises means for accomplishing spring coupling including at least one spring device. The invention is characterized by the following features: each spring device comprises at least two spring elements; the spring element of the spring device are pretensioned; the spring element of a spring device are allocated to the primary and the secondary masses in such a way that the spring elements are supported against each other.
