Abstract
A damper used to damp roll vibration of an automotive power unit includes housing in which a disc is immersed in a highly viscous liquid, and a linkage which has universal joints formed at each end thereof. The linkage induces relative rotation between the housing and the disc. A resilient vibration attenuating arrangement is included in one or both of the universal joints for insulating the vehicle chassis from vibration which tends to be freely transmitted through the damper per se and cause cabin reverberation noise.
