Title:
VIBRATION DAMPING DEVICE HAVING MULTI-STAGE TORSION DAMPER
Document Type and Number:
WIPO Patent Application WO/2023/128634
Kind Code:
A1
Abstract:
The present invention relates to a vibration damping device which comprises two or more damping units which are connected in parallel and coaxially arranged, each comprising at least one input part and at least one output part. An output part of a first damping unit and an input part of a second damping unit are coupled so as to be fixed to each other in the rotational direction, and the output part of the first damping unit and the input part of the second damping unit each have a center hole through which a sliding shaft can pass, wherein the diameters of the center holes are different from each other. When the output part of the first damping unit and the input part of the second damping unit are aligned on the sliding shaft while being coupled to each other, one of the output part of the first damping unit and the input part of the second damping unit having the center hole with a smaller diameter is configured such that the surface of the center hole abuts a sliding surface of the sliding shaft, whereas the other having the center hole with a larger diameter is configured such that the surface of the center hole is radially spaced from the sliding surface.
