摘要： 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.
