Abstract
A torsional vibration damper is capable of neutralizing vibrations with a relatively large amplitude, and includes a pair of strengthened equalizers. The damper transmits a torque between a drive plate operatively connected to a torque input member, and hub operatively connected to a torque output member. The hub has a plurality of hub arms extending outward from its outer periphery with an equal angular. A pair of equalizers is journalled on the outer peripheries of and floating independently of said hub arms, each equalizer including an annular portion and arm portions extending inward from the inner periphery of the annular portion. The arm portions of two equalizers alternate between neighboring hub arms. Compression spring sets are interposed in serial between the arm portions of both the equalizers and between the arm portions and the hub arms. The drive plate engages the groups of the compression spring sets by means of both the side inner edges of arcuate windows which are defined in the drive plate and have the same arclength to that of the neighboring hub arms.
