Torsionsschwingungsdämpfer mit Wälzkörpern als Koppelelemente

摘要

A torsional vibration damper has a plurality of transmission elements which are rotatable relative to one another about a common axis of rotation. The relative movement of the transmission elements is carried out by the deflection of coupling bodies which are displaceable between the transmission elements along guide paths. A first guide path is provided on at least one of the transmission elements enabling a movement of the respective coupling body in the circumferential direction. The first guide path has a curvature which is formed with a curvature location having the maximum distance from the axis of rotation. A second guide path substantially free of curvature is provided on at least another transmission element allowing a movement of the coupling body in the radial direction. The coupling body is substantially free of curvature at least along a predeterminable portion of a contact zone facing the second guide path.
