    Abstract: Provided is torsion damper for a vehicle including an output side-flywheel coupled to an output shaft of a driving unit in an axial direction, a first drive plate disposed to be relatively rotatable in an axial direction of the output side-flywheel, a second drive plate disposed to be relatively rotatable in an axial direction of the first drive plate, an input shaft of a transmission being coupled thereto in the axial direction, a first damper member installed between the output side-flywheel and the first drive plate and configured to absorb vibration and impact generated in a rotation direction thereof, and a second damper member installed between the first drive plate and the second drive plate and configured to absorb vibration and impact generated in a rotation direction thereof.

    Abstract: A power transmission device includes a flywheel and a damper device. The flywheel includes a plurality of fixation holes. The damper device includes an input rotary member, an output rotary member, and a pair of first elastic members. The input rotary member and output rotary member each include a plurality of assembling holes disposed in corresponding positions to the plurality of fixation holes of the flywheel. The plurality of assembling holes are arranged in a circumferential direction such that two pairs of the assembling holes, each pair including two adjacent assembling holes, are each disposed at a larger interval than remaining assembling holes to produce a pair of accommodation spaces. A pair of first accommodation portions, accommodating the pair of first elastic members, is disposed radially outside the pair of accommodation spaces.

    Abstract: A lock-up device includes a clutch part, an input plate, an outer peripheral side damper part, an output plate, an inner peripheral side damper part, and an intermediate member. The outer peripheral side damper part includes at least two outer peripheral side springs. The outer peripheral side springs are disposed in a circumferential alignment, act in series, and take circular-arc shapes when in a free state. The inner peripheral side damper part includes at least two inner peripheral side springs. The inner peripheral side springs are disposed in a circumferential alignment on an inner peripheral side of the outer peripheral side damper part, and act in series. The intermediate member is rotatable relatively to the input plate and the output plate, and makes the outer peripheral side damper part and the inner peripheral side damper part act in series.

    Abstract: A torsional damper assembly for a vehicle powertrain is provided and is configured to dampen torsional vibration transfer between an engine and a transmission of the vehicle. The assembly includes a hub having a flange defining a window, a biasing mechanism disposed at least partially within the window and configured to absorb a first portion of the torsional vibration from the engine, and a damper body disposed at least partially within the window. The damper body is formed from at least one of a viscoelastic material and a viscoplastic material, and is configured to dampen a second, different portion of the torsional vibration and radial forces from the engine such that the biasing mechanism and the damper body cooperatively dampen the torsional vibration transfer between the engine and the transmission.
