Abstract:
A torsional vibration damper, comprisinga drive-side damper element rotatable about an axis of rotation and having a plurality of drive-side guide paths, said plurality of drive-side guide paths comprising first drive-side guide paths and second drive-side guide paths;a driven-side damper element rotatable relative to said drive-side element about said axis of rotation and having a plurality of driven-side guide paths, said plurality of driven-side guide paths comprising first driven-side guide paths and second driven-side guide paths, wherein said first drive-side guide paths and said first driven-side guide paths comprise first guide paths extending farther in the circumferential direction than in the radial direction and said second drive-side guide paths and said second driven-side guide paths comprises second guide paths extending farther in a radial direction that in the circumferential direction; anda damping device arranged between said drive-side damper element and said driven-side damper element for transmitting torque between said drive side damper element and said driven-side damper element such that said driven-side damper element is rotatable relative to said drive-side damper element against an action of said damping device,said damping device comprising a plurality of coupling bodies, at least one of said plural coupling bodies being received one of said first guide paths and one of said second guide paths, wherein said coupling body undergoes a deflection in at least one of said first guide path and said second guide path during a relative movement between the drive-side damper element and the driven-side damper element, wherein at least one of said plurality of drive-side guide paths and said plurality of driven-side guide paths is arranged in a succession in which one of said first guide paths is arranged circumferentially adjacent to one of said second guide paths.
