Abstract:
A torsional vibration damping device, comprising:a hub having external splines;first and second cover plates connected together and held apart at an axial distance such that said first cover plate is fixed with respect to rotation relative to said second cover plate, wherein one of said first and second cover plates is mounted on said hub such that said first and second cover plates are rotatable relative to said hub about an axis of rotation and the other one of said first and second cover plates is operatively arranged such that a radial free space is defined between the other one of said first and second cover plates and said hub, said first and second cover plates being axially loaded in opposing directions via a spring force;an internally located part arranged between said first and second cover plates and rotatable within a fixed angular range relative to said first and second cover plates;a torsion spring circumferentially arranged between said internally located part and said first and second cover plates so that said internally located part rotates relative to said first and second cover plates against an urgency of said torsion spring, said first and second cover plates, said internally located part and said torsion spring comprising a main damper;andat least one stop surface arranged on said external splines so that said internally located part is supported against said stop surface for axially securing said hub via said spring force.
