Abstract
A torsional vibration damper, in particular for clutches, includes a primary structural unit and a secondary structural unit which are rotatable relative to one another and connected to each other by a spring arrangement (,) including at least one thrust piston (,). At least the secondary structural unit (,) interacts with the thrust piston (,) of the spring arrangement via a contact surface with a radially directed surface component, wherein the contact surface (,) is formed on a separate third structural unit (,) situated between the secondary structural unit (,) and the spring arrangement (,), thereby ensuring a structurally simple heat insulation for a torsional vibration damper.
