Abstract
A torsional vibration damper, which may be in the form of a twin mass flywheel, and which has an input member (11) designed to rotate generally in a first plane (A1), an output member (12) designed to rotate generally in a second plane (A2), relative rotation of the input and output members being possible against the action of a link-type damper (40). The damper is arranged to allow the first and second planes in which the input and output members rotate to tilt relative to each other during use of the damper to relieve internal stresses. This ability to tilt may be provided by self-aligning main bearings (50) or by the use of self-aligning pivot bearings (65) in the link-type damper.
