Abstract
A torsion isolator assembly (30) for reducing driveline torsionals includes a vane damper (36) including improved valving (40d,40e) for increasing the damping factor of the damper, improved spiral springs (32,34 or 80,82) for reducing spring stress primarily due to centrifugal forces, and cam surfaces (44d,44c) for further reducing spring stress due to centrifugal forces.
