Abstract
A torsional vibration damper includes a drive-side primary element having at least one primary dog, an output-side secondary element having at least one secondary dog, and at least one spring device between the primary and secondary dogs for spring-elastic coupling of the primary element to the secondary element and including a plurality of spring elements. A separator sheet includes a ring element. At least one sliding block extends from the ring element between adjacent spring elements and is arranged circumferentially about the spring elements. The primary element has also an inner part having an external toothing, an outer part on which the primary dog is arranged and having an internal toothing engaging into the external toothing, and at least one damping part arranged between the external and internal toothing for vibration damping between the inner and outer parts.
