Abstract:
A torsional vibration damper comprising an input member designed to rotate in a first plane, an output member designed to rotate in a second plane, main bearing means supporting the input and output members for relative rotation, and damping means for controlling said relative rotation, said damping means including at least one linkage arrangement having a first link pivotally mounted on one of the members and connected with the other member via a second link, one end of said second link being pivotally connected with the first link and the other end of said second link being pivotally connected with the other member, at least one of the pivotal connections between the first and second links and the pivotal connection of each link with its respective input or output member being in the form of a self-aligning pivot bearing which allows the first and second planes in which the two members rotate to tilt relative to each other during use of the damper.
