Abstract:
A torsional vibration damping apparatus, comprising an input component and an output component, said input and output components being rotatable with and relative to each other about a common axis; at least one damper arranged to oppose said relative rotation comprising input and output elements rotatable respectively with said input and output components, said input and output elements being movable relative with each other along said axis, each of said elements having at least one pocket; and at least one energy storing device deformable in a circumferential direction of said elements and extending into the at least one pocket of said input element and into the at least one pocket of said output element, said elements having surfaces bounding said pockets thereof positioned and configured to locate the at least one energy storing device radially and along said axis, each of said elements further having confining means for said at least one energy storing device and cooperating therewith to couple said elements against movement relative to each other along said axis.
