Abstract:
A torsional vibration damper for use in a clutch, comprising a primary structural unit and a secondary structural unit frictionally engageable with a complementary component of a clutch, said primary and secondary structural units being rotatable relative to one another and connected to each other by a spring arrangement (7) including at least one thrust piston (71), with at least the secondary structural unit (2) interacting with the thrust piston (71) of the spring arrangement via a contact surface with a radially directed surface component, said contact surface (4) being formed on a separate third structural unit (3) situated between the secondary structural unit (2) and the spring arrangement (7) so that the second structural unit interacts with the spring arrangement via the third structural unit and an effective insulation of the spring arrangement from heat generated in the area of the frictional engagement of the secondary structural unit is realized, wherein the third structural unit (3) is so connected to the secondary structural unit (2) as to rotate with the secondary structural unit (2).
